Treatment of bleeding esophageal varices with cyanoacrylate and polidocanol, or polidocanol alone: results of a prospective study in an unselected group of patients with cirrhosis of the liver.

BACKGROUND AND STUDY AIMS: Data concerning the results with emergency and further elective therapy of esophageal varices using polidocanol and cyanoacrylate, or polidecanol alone, in an unselected group of patients with liver cirrhosis have not previously been available. The aim of the present prospective study was to evaluate acute and repeated cyanoacrylate and polidocanol therapy in the emergency and long-term elective management of esophageal varices. METHODS: In accordance with the protocol of the present prospective study, acutely bleeding esophageal varices of grades 1 to 3 were treated endoscopically with polidocanol injection, while grade 4 varices, large solitary varices (over 5 mm) and otherwise uncontrollable cases of variceal bleeding were treated by injection of cyanoacrylate and polidocanol. Over a period of 62 months, 112 patients (65 men, 47 women) with acute bleeding from esophageal varices due to cirrhosis of the liver (69% alcohol-related) underwent a total of 245 treatment sessions in hospital. The average age of the patients was 62.0 +/- 12.3 years (58.1% were 60 or older). Hepatic function corresponded to Child-Pugh class A in 38 patients (33.9%), Child-Pugh class B in 68 patients (60.7%), and Child-Pugh class C in six (4.5%). RESULTS: Sixty-eight patients (60.7%) were treated with polidocanol alone, and 44 (39.3%) with cyanoacrylate and polidocanol. Acute hemostasis was achieved in all cases. In 5.7% of the sclerotherapy procedures, bleeding ulcers were observed, and a pleural effusion was seen in one case. The hospital mortality rate was 24.1%, resulting from the bleeding in 2.7% and due to liver failure in the remaining cases. Recurrent bleeding occurred within 24 hours in four patients (3.6%), and during the later course of the hospital stay in a further 11 patients (9.8%). The mean survival time was 13.7 +/- 17.7 months. Over the entire observation period of 23 +/- 21 months, 67 patients died (59.8%); the cause of death was hemorrhage in 4.5%, the underlying hepatic disease in 65.7%, and non-hepatic causes in 29.8%. Recurrent bleeding occurred in 58 patients (51.7%). The cumulative survival rate in the patients treated with cyanoacrylate and polidocanol was 66 +/- 15% and 26 +/- 32% after one and five years, respectively, and 56 +/- 13% and 33 +/- 19% in those treated with polidocanol alone. CONCLUSIONS: Endoscopic treatment of esophageal varices with cyanoacrylate and polidocanol, or polidocanol alone, is effective in controlling bleeding, and the complication rate is tolerable. The short-term and long-term mortality rates are determined largely by the underlying liver disease.

Single-blind, randomized study comparing chromated glycerin, polidocanol solution, and polidocanol foam for treatment of telangiectatic leg veins.

BACKGROUND: A single-blind, randomized, comparative study was performed to evaluate the efficacy of pure chromated glycerin (CG), polidocanol (POL) 0.25% solution, and POL 0.25% foam (Monfreux technique) for treatment of telangiectasias and reticular leg veins. OBJECTIVE: To determine the relative efficacy and safety of two sclerosing agents and foam. METHOD: Of 150 randomized patients presenting comparable areas (lateral face of thigh) of telangiectasias and reticular leg veins, 147 could be evaluated by photographic assessment, patients' satisfaction score, and pain at injection sites. Internal and external agreement for the photographic assessment was good for two independent blinded experts. RESULTS: CG cleared vessels significantly better than POL solution or foam (p<0.002). The patients' satisfaction score was also higher in the CG group, although the difference did not reach statistical significance. CG was significantly more painful at injection sites. Other side effects were very few, precluding any statistical comparison. Foam was associated with more side effects (microthrombi, matting) than CG or POL solution. Three patients treated with POL foam experienced a transient visual disturbance. CONCLUSION: This study shows that CG is superior to POL solution and foam for sclerotherapy of leg telangiectasias.

Polidocanol at different concentrations for pleurodesis in rats.

PURPOSE: We previously found that 0.5% polidocanol was more effective than tetracycline for pleurodesis in rats. Thus, we conducted the present study to evaluate the efficacy of different concentrations of polidocanol for pleurodesis in rats. METHODS: We divided 54 albino Wistar rats into six groups. Groups 1, 2, and 3 were given isotonic saline, 35 mg/kg tetracycline, and 0.6 mg of diluted polidocanol, respectively, being the daily recommended dose for humans. Groups 4, 5, and 6 were given 0.5%, 1%, and 2% polidocanol, respectively. All solutions were given intrapleurally in a volume of 0.5 ml. We examined the rats for macroscopic pleural adhesions and compared the mean values of macroscopic scoring among the six groups. RESULTS: The rats given polidocanol and tetracycline had significantly more adhesions than the control group, and polidocanol at concentrations of 0.5%, 1%, and 2% was more effective for pleurodesis than tetracycline. The diluted polidocanol was not more effective than tetracycline. There was no difference between the effects of the 0.5% and 1% concentrations, but the 2% polidocanol group had significantly more adhesions than the other groups. CONCLUSIONS: Polidocanol at concentrations of 0.5%, 1%, and 2% was a more effective sclerosing agent than tetracycline for pleurodesis. While 2% polidocanol was the most efficient sclerosing agent, the daily maximum recommended dose of polidocanol for humans was not more effective than tetracycline.

The Australian polidocanol (aethoxysklerol) study. Results at 2 years.

BACKGROUND: An ongoing study of the safety and effectiveness of polidocanol by 98 investigators in Australia infecting 16,804 limbs over 2 years. OBJECTIVE: To evaluate the complications of polidocanol and compare its effectiveness and complications with sodium tetradecyl sulphate (STD) and hypertonic saline. METHODS: A single-arm prospective study of polidocanol complications and its effectiveness as a sclerosant was performed. This was compared with each investigator's previous experience with other sclerosing agents. Patients had either varicose veins or venule ectasias and/or spider veins (telangiectasia). A total of 16,804 limbs were injected by 98 investigators. Sclerotherapy was performed with 0.5% or 1% polidocanol for telangiectasias or spider veins, and with 3% polidocanol for varicose veins. The effectiveness of the sclerotherapy and any complications were reported during a 2-year period. RESULTS: There were very few complications reported with polidocanol. There were no reported deaths or anaphylaxis. The investigators with previous experience of other sclerosants considered that the effectiveness of polidocanol was superior to STD (85%) and hypertonic saline (84%). Ninety percent of investigators considered that polidocanol had less frequent complications than STD, and 80% considered that these were less severe. Seventy-four percent considered that polidocanol had fewer side effects than hypertonic saline, and 74% considered that these were less severe. CONCLUSIONS: Polidocanol is an effective sclerosant that has few complications.

Hepatotoxic effects of polidocanol in a model of autologously perfused porcine livers.

Polidocanol is an effective sclerosing agent that consists of 95% hydroxypolyethoxydodecane and 5% ethyl alcohol and is known to have a low risk of complications. However, since the compound has been proposed for the local treatment of liver diseases, the potential for topical hepatic side effects should be examined. Therefore, the new model of normothermic-hemoperfused isolated porcine slaughterhouse livers was used to examine polidocanol-hepatotoxicity encompassing the advantages of slaughterhouse organs to reduce animal experiments and autologous blood as an optimal perfusate. Polidocanol was administered via the hepatic artery and portal vein and the effects of the sclerosant on organ function parameters were compared with those in an untreated control group. In contrast to the untreated control organs, significant differences were found in the polidocanol group for parameters such as alanine aminotransferase or organ weight after perfusion. The most striking differences were found for hepatic bile flow, which dropped in the polidocanol group to 0.24+/-0.02 ml/min per 1000 g after administration of the compound compared with 3.80+/-1.08 ml/min per 1000 g in the control group. In summary, the present observations indicate a risk of hepatotoxic effects of polidocanol. Clinicians should be aware of this problem and the use of polidocanol for intrahepatic sclerosing should be restricted to specialized centers.

Randomised trial of single and repeated fibrin glue compared with injection of polidocanol in treatment of bleeding peptic ulcer.

BACKGROUND: Although injection treatments for ulcer haemostasis seem to be effective, recurrent bleeding remains a serious problem. Large randomised clinical trials are required to show differences between treatment modalities for gastrointestinal bleeding. The aim of this study was to compare the safety and efficacy of repeated endoscopic injection of fibrin glue (FG) with that of single endoscopic injection of polidocanol in the prevention of recurrent bleeding. METHODS: 854 patients with active gastroduodenal bleeding (spurting, oozing), or ulcers with a visible non-bleeding vessel, were randomly assigned one of three endoscopic treatments: single application of polidocanol 1%, single application of FG, or daily repeated application of FG until the visible vessel had disappeared. All patients were pretreated with local injection of epinephrine (1/10,000), and had daily repeat endoscopies until the vessel observed at initial endoscopy was no longer visible. FINDINGS: Recurrent bleeding rates among the 790 patients in whom the rates could be assessed were 58 (22.8%) of 254 in the polidocranol group, 51 (19.2%) of 266 in the FG-single group, and 41 (15.2%) of 270 in the FG-repeated group. The difference between FG-repeated treatment and polidocanol was significant (p = 0.036). Treatment failed, making other treatments (including surgery) necessary, in 34 (13.0%) of 261 in the polidocanol group, 34 (12.4%) of 274 in the FG-single group, and 21 (7.7%) of 274 in the FG-repeated group. The difference between FG-repeated treatment and polidocanol was significant (p = 0.046). The 30-day-mortality rates were low in all three treatment groups (polidocanol 4.7%; FG-single treatment 5.3%, FG-repeated treatment 4.3%). The safety profiles of the three treatment strategies were similar. INTERPRETATION: Repeated injection with FG glue is significantly more effective than injection with polidocanol 1% in the treatment of bleeding from gastroduodenal ulcers.

Comparison of polidocanol and tetracycline in the sclerotherapy of testicular hydrocele and epididymal cyst.

OBJECTIVE: To compare the effects and side-effects of polidocanol and tetracycline when used as sclerosants for testicular hydrocele and epididymal cyst. PATIENTS AND METHODS: Forty-five men (median age 67 years, range 42-81) with 46 hydroceles or epididymal cysts were assessed. After puncture and aspiration, the empty sac was instilled with either polidocanol or tetracycline, assigned randomly. Patients recorded any treatment-associated pain on a visual analogue scale. RESULTS: At 9 months of follow-up, nine of 17 men were cured after sclerotherapy with polidocanol compared with 17 of 20 men treated with tetracycline (P < 0.05). Tetracycline produced some pain for 3 days after treatment while polidocanol therapy was almost pain-free. Re-instillation should be considered for recurrences. At the follow-up after 35 months, 16 of 18 men treated with polidocanol and 20 of 22 men treated with tetracycline were satisfied with the outcome. CONCLUSION: Both polidocanol and tetracycline are useful sclerosants for treating testicular hydrocele and epididymal cyst. We prefer polidocanol as a first choice in older patients because there were few short-term side-effects.

Endoscopic injection sclerotherapy in non-variceal upper gastrointestinal bleeding. A comparative study of polidocanol and thrombin.

To date several agents have been used to achieve haemostasis in patients with non-variceal upper gastrointestinal bleeding using endoscopic sclerotherapy techniques. Polidocanol has been widely used but local complications have been reported after treatment. We have compared the efficacy and safety of thrombin and polidocanol in 82 consecutive patients with ongoing or recent bleeding from duodenal, gastric, or anastomotic ulcers. Primary control of haemostasis from spurting vessels was achieved in 90% of cases using polidocanol and in 86.6% using thrombin. Definitive haemostasis was obtained in 80% of patients in both groups. When a non-bleeding vessel was visible, injection of polidocanol or thrombin effectively prevented rebleeding in 90.9% and 85.7% of cases, respectively. When a non-bleeding sentinel clot was present, injection of polidocanol or thrombin provided definitive haemostasis in 100% and 92.8% of cases, respectively. No statistically significant difference was evident between the two agents. In the polidocanol group, one local haemorrhagic complication was noted. No general or local complications were recorded in the thrombin group.

The efficacy of polidocanol in pleurodesis in rats.

PURPOSE: Pleurodesis is used to treat pleural effusions, and a number of agents with varying degrees of efficacy and systemic toxicity have been trialed. This study was conducted to evaluate the efficacy and systemic toxicity of polidocanol in pleurodesis. METHODS: Thirty albino Wistar rats were divided into three groups of ten rats each. Group 1 (control) was given isotonic saline, group 2 was given 35 mg/kg tetracycline, and group 3 was given 2.5 mg 0.5% polidocanol, all intrapleurally in a total volume of 0.5 ml. The rats were killed on postoperative day 30 and the macroscopic pleural adhesions and microscopic evidence of inflammation were evaluated. Hepatic, renal, and pancreatic function tests were done and various tissues were microscopically examined to detect systemic toxicity. The mean values of macroscopic and microscopic scoring and biochemical parameters were compared among the three groups. RESULTS: The polidocanol- and tetracycline-treated rats had significantly more adhesions than the control group rats, and polidocanol was more effective for pleurodesis than tetracycline (P = 0.027). Microscopic scoring was similar in the polidocanol- and tetracycline-treated rats, being significantly higher than that in the control rats. No significant difference was found in the biochemical parameters among the three groups. There were no signs of toxicity in any of the tissues studied microscopically. CONCLUSIONS: Polidocanol was found to be a more effective sclerosing agent than tetracycline for pleurodesis. Systemic toxicity was not shown by the biochemical parameters and histopathologic findings.

Transcervical polidocanol as a nonsurgical method of female sterilization: a pilot study.

We have studied the effects of transcervically administered polidocanol on uterine and fallopian tube morphology in Wistar rats and Rhesus monkeys. Polidocanol is a synthetic, long-chain fatty acid that is widely used as a sclerosing agent in Europe. The goal of the study was to determine whether polidocanol would safely cause tubal occlusion in an animal model. Twenty female Wistar rats and three female Rhesus monkeys underwent transcervical injection of polidocanol or physiological saline. The animals were followed for 30 days and then a lower laparotomy was performed, with excision of the entire upper reproductive tract. Specimens were subsequently examined for macroscopic and microscopic changes. Only cyclic changes were observed in the control animals of both species. Fifteen macroscopic and 37 microscopic changes were observed in the uterine horns of the 10 rats treated with polidocanol. There was no observed effect in the monkey fallopian tube. These results suggest that species differences that exist between rodents and primates may influence the effects of transcervical polidocanol. Experiments using a primate model are needed as proof of concept prior to human studies of candidate agents for transcervical tubal sterilization.

Treatment of essential telangiectasia: effects of increasing concentrations of polidocanol.

A double-blind, double-paired comparison study was performed to evaluate the effects of increasing concentrations of polidocanol in the sclerotherapy of essential telangiectasias of the legs. Polidocanol 0.25%, 0.50%, 0.75%, and 1.0% were compared with regard to clinical effectiveness, safety, and patient acceptance. All dosages were well tolerated by the patients. There were no allergic reactions to polidocanol and no cases of superficial ulceration nor necrosis. Among those whose veins cleared, there was little difference in time to clearing for the four concentrations, which averaged three to four treatment sessions. No statistically significant differences existed among the four dosages with respect to level of improvement, itching, or neovascularization. Polidocanol 0.75% and 1.0%, however, caused more side effects noted by patients and induced more hyperpigmentation than did the lower concentrations. Polidocanol 0.25% yielded the lowest percentage of patients whose veins cleared. The 0.50% solution was the most effective concentration for total overall clearing of the types of vessels treated in this study. From this information it appears that 0.50% polidocanol may be the sclerosing agent of choice.

Allergic reactions to polidocanol for vein sclerosis. Two case reports.

BACKGROUND: Polidocanol is a sclerosing solution that is highly valued by clinicians and patients for its painlessness, high efficacy, excellent safety profile, low incidence of side effects, and for the rarity of its allergic reactions. Previous estimates of the incidence of allergic reactions have ranged from 0 to 0.06%. OBJECTIVE: Improved recognition of systemic allergy to polidocanol is desirable for both clinicians and for patients. We have attempted to describe two cases recently observed in our population and to provide an improved upper-bounds estimate for the true population incidence of allergy to polidocanol. RESULTS: We report two recent cases of mild systemic allergic reaction to polidocanol in a population of 689 exposed patients, for an observed incidence of 0.3% in our patient population. We have calculated a 95% confidence upper-bound estimate of 0.91% for the incidence of polidocanol allergy in the general population. CONCLUSION: Allergy to polidocanol may be more common than previously recognized. Careful questioning of previously treated patients and more prolonged observation of patients after treatment may yield a larger number of recognized cases.

Suppression of intrinsic resistance to penicillins in Staphylococcus aureus by polidocanol, a dodecyl polyethyleneoxid ether.

With polidocanol, it was possible to reduce the MIC as well as the MBC of methicillin, oxacillin, penicillin G, and ampicillin against resistant staphylococci. The strongest effects were obtained with methicillin and oxacillin. All strains tested could be resensitized to these penicillins independent of the original resistance levels. Polidocanol was not inhibitory by itself for Staphylococcus aureus. Furthermore, it did not inhibit the activity of staphylococcal beta-lactamase. This permits the conclusion that an intrinsic resistance mechanism is affected by this substance. Its action cannot be simply explained by an improved accessibility of the penicillin targets as uptake, and binding of methicillin and penicillin G in resistant cells was not changed by polidocanol. On the other hand, the lysis induced by combinations of this substance with small amounts of a penicillin was antagonized by chloramphenicol. This suggests that autolytic enzymes are involved in the polidocanol effect and possibly in the intrinsic resistance mechanism itself. Before polidocanol can trigger lysis, the penicillin must act first in some way. As could be seen with a susceptible strain, the resulting lysis did not exceed that obtained with penicillins alone. Thus, polidocanol does not exhibit an independent lytic mechanism but obviously is able to substitute penicillins in their lytic action.

Prospective randomized comparison of sodium tetradecyl sulphate & polidocanol for oesophageal variceal sclerotherapy.

BACKGROUND & OBJECTIVE: A number of sclerosing agents have been tried for sclerotherapy of oesophageal varices. However, none of them have emerged as an ideal agent. Hence, this study was designed to compare the efficacy and safety of sodium tetradecyl sulphate and polidocanol for sclerotherapy of oesophageal varices. METHODS: A total of 100 consecutive patients with bleeding oesophageal varices were included in the study. Patients with associated gastric varices and hypersplenism were excluded. Of the 100 patients, 50 received emergency sclerotherapy with either 3 per cent sodium tetradecyl sulphate or 3 per cent polidocanol, randomized using the sealed envelope technique. Following control of bleeding, these patients were included in the elective sclerotherapy schedule. The remaining 50 patients with past history of bleeding varices received elective sclerotherapy. Thus all 100 patients received elective sclerotherapy at 4 weekly intervals. RESULTS: There was no significant difference between the sodium tetradecyl sulphate and polidocanol groups with respect to the control of acute variceal bleeding (100% vs 96%), the mean number of injection sessions (4.5 +/- 0.3 vs 4.7 +/- 0.4) and the mean amount of scleroscent required (33.3 +/- 2.7 ml vs 37.0 +/- 3.3 ml) per patient for variceal eradication. The cost of polidocanol required for variceal obliteration was significantly higher than that of sodium tetradecyl sulphate (P < 0.001). The use of sodium tetradecyl sulphate in contrast to polidocanol was associated with a significantly higher incidence of variceal recurrence (11% vs 0%) and other complications such as oesophageal ulcer (14% vs 2%), retrosternal pain (22% vs 2%), fever (16% vs 4%), tachycardia (14% vs 2%) and dysphagia (20% vs 6%). Rebleeding rate and mortality rate were not significantly different between the two groups. INTERPRETATION & CONCLUSION: Polidocanol is superior to sodium tetradecyl sulphate as it has lower incidence of complications, even though the drugs are similar in efficacy in the control of bleeding and obliteration of varices in long-term.

Efficacy of endoscopic clipping for actively bleeding peptic ulcer: comparison with polidocanol injection therapy.

BACKGROUND/AIMS: The use of hemostatic clips is conceptually attractive for achieving definitive hemostasis in peptic ulcer bleeding. There are only a few clinical trials comparing clipping with other endoscopic hemostatic methods. The aim of this study is to assess the efficacy and safety of endoscopic clipping with that of injection of polidocanol for hemostasis from actively (spurting or oozing) bleeding peptic ulcer. METHODOLOGY: 61 patients with active (spurting or oozing) bleeding gastroduodenal ulcers were randomly assigned to one of two endoscopic treatments: injection therapy with polidocanol 1% (injected in 0.5-1.0 mL increments at three to five sites around the bleeding vessel to a total of 5 mL) (n=30), or endoscopic clipping using a clipping device and clips (n=31). All patients from the polidocanol group and 22 (68.8%) patients from the clipping group received pretreatment with epinephrine. Hemostatic rates, rebleeding rates, amounts of blood transfusion, and durations of hospital stay were analyzed. RESULTS: The initial hemostatic rate was 96.8% in the clipping group, and 96.7% in the polidocanol group, respectively. Mean transfusion requirements, mean number of hospital days and percentage needing surgery were comparable in both groups. Recurrent bleeding rates were higher, although not statistically significant in the polidocanol group than in the clipping group (13.3% vs. 6.5%, respectively). CONCLUSIONS: Our data suggest that injection therapy with polidocanol and endoscopic hemoclips seems to be equivalent for actively (spurting and oozing) bleeding peptic ulcer.

Prospective randomized comparison of sodium tetradecyl sulfate and polidocanol as variceal sclerosing agents.

A prospective randomized controlled study was designed to evaluate differences in efficacy and complication rate between the two most commonly used sclerosing agents, sodium tetradecyl sulfate (STD) and polidocanol. Of 52 patients with esophageal variceal bleeding, 26 were randomized to receive sclerotherapy with 1.5% STD and 26 to receive 1% polidocanol at weekly intervals. Eradication of varices was achieved in 88% patients each of the STD and polidocanol group. There was no significant difference between patients injected with STD and polidocanol with regard to re-bleeding (27% vs. 15%) and mortality (11.5% in both). The use of STD, in contrast to polidocanol, was associated with a higher incidence of complications in terms of severe retrosternal pain (27% vs. 4%), deep ulceration (53% vs. 23%), dysphagia (88% vs. 46%), and stricture formation (27% vs. 8%). It was concluded that these two agents were similar in efficacy. However, polidocanol was superior due to a lower incidence of complications.

Sclerosing agents in the treatment of telangiectasia. Comparison of the clinical and histologic effects of intravascular polidocanol, sodium tetradecyl sulfate, and hypertonic saline in the dorsal rabbit ear vein model.

A 0.25-mL quantity of 0.25%, 0.5%, and 1.0% polidocanol (Aethoxysclerol [France]), 0.5% sodium tetradecyl sulfate (Sotradecol injection), and 23.4% hypertonic saline was injected into the dorsal marginal rabbit ear vein; clinical and histologic thrombosis resulted that lasted between four and eight days. The lowest concentration of polidocanol (0.25%) demonstrated immediate thrombosis; however, no clinical or histologic changes occurred eight days after injection. With all other agents, histologic fibrosis of the vessel correlating with clinical disappearance occurred after eight days. However, 0.5% polidocanol and sodium tetradecyl sulfate developed recanalization through the initially sclerosed vessel between eight and 14 days, with clinical reappearance of the 0.5% polidocanol-injected vessel at 30 days, after injection. Cutaneous necrosis was noted clinically and histologically in three of ten vessels injected with 1.0% polidocanol and in two of ten vessels injected with hypertonic saline. Clinical and histologic evidence of necrosis occurred with and without extravasation of the sclerosants.

Sclerosing polidocanol injections to treat chronic painful shoulder impingement syndrome-results of a two-centre collaborative pilot study.

The histological changes found in the supraspinatus tendon have similarities with the findings in Achilles-, patellar- and extensor carpi radialis brevis (ECRB)-tendinopathy. In recent studies, we have found a vasculo-neural ingrowth in chronic painful Achilles and patellar tendinopathy, and demonstrated good short-term clinical effects with injections of the sclerosing substance polidocanol. In this collaborative two-centre pilot study, 15 patients (10 males and 5 females, mean age 46 years) with a long duration of shoulder pain (mean 28 months), and given the diagnosis chronic painful shoulder impingement syndrome, were included. They had tried rest, traditional rehabilitation exercises and multiple subacromial corticosteroid injections, without effect. We found vascularity (neovessels) in chronic painful, but not in pain-free, supraspinatus tendons, and prospectively studied the clinical effects of ultrasound (US) and colour Doppler (CD)-guided injections of polidocanol, targeting the area with neovessels. The patients evaluated the amount of shoulder pain during horizontal shoulder activity on a visual analogue scale (VAS), and satisfaction with treatment. Two (median) (range 1-5) polidocanol treatments (with 4-8 weeks in between) were given. In four patients (considered treatment failure), cortisone was injected into an inflamed subacromial bursa at one separate occasion weeks after the last polidocanol injection. At follow-up, 8 (median) (range 4-17) months after the treatment, 14 patients were satisfied with the result. Using the visual analogue scale evaluation (VAS), the pain dropped from 79 before treatment to 21 at follow-up (P < 0.05). In the short-term perspective, sclerosing polidocanol injections targeting the neovessels in the supraspinatus tendon and/or bursa wall seems to have a potential to reduce the pain during shoulder loading activity.
