Treatment of long-distance intermittent claudication with pentoxifylline: a 12-month, randomized trial.

The efficacy, safety, and cost of pentoxifylline (PXF) in long-range (>400 m interval) intermittent claudication was studied comparing PXF and placebo in a 12-month study. A standardized treadmill test was performed at inclusion and at 6 and 12 months. A training plan based on walking was associated with the control of risk factor levels. Of the 194 included patients, 135 completed the study: 75 in the PXF group and 60 in the placebo group. There were 59 dropouts (due to low compliance). The authors observed a 148% increase in total walking distance (TWD) at 6 months with PXF (vs 110% with placebo; p<0.05); at 12 months, the increase was 170% with PXF (vs 131% with placebo; p<0.02). There was a 38% difference at 6 months and 39% at 12 months in favor of PXF. Treatment was well tolerated. In conclusion, PXF improved walking distance significantly better than placebo.

Intermittent claudication in diabetics: treatment with exercise and pentoxifylline--a 6-month, controlled, randomized trial.

The aims of this study were to evaluate the effect of PXF (1600 mg daily) in diabetic patients with intermittent claudication. Of the 60 included patients, 53 completed the study (27 in the PXF group). There were seven dropouts. The groups were comparable for age, sex distribution, and total walking distance (TWD), and risk factors. There was an increase in TWD at 3 and 6 months in both groups (p<0.05) possibly due to exercise. However the increase (both absolute and percentage) in TWD was significantly larger in the PXF group. At 6 months, PXF produced a 292% increase in TWD (vs 180% produced by placebo) (p<0.02). The excess increase produced by PXF treatment was 112% at 6 months in comparison with placebo (p<0.02). Treatment was well tolerated. Between-group analysis favors PXF considering TWD, and results indicate good efficacy and tolerability.

Treatment of intermittent claudication with pentoxifylline: a 12-month, randomized trial--walking distance and microcirculation.

The efficacy, safety and cost of pentoxifylline (PXF) in severe intermittent claudication was studied comparing PXF and placebo in a 12-month study. A treadmill test and microcirculatory evaluation with laser Doppler flowmetry were performed at inclusion and at the end of 6 and 12 months. A physical training plan (based on walking) and reduction in risk factor levels plan was used in both groups. Of the 120 included patients, 101 completed the study: 56 in the PXF group and 45 in the placebo group. There were 19 dropouts (due to low compliance). The two groups were comparable for age, sex distribution, walking distance, and the presence of risk factors and smoking. Intention-to-treat analysis indicated a 268% increase in walking distance in the PXF group (vs 198% in the placebo group; p<0.05) at 6 months and an increase of 404% (vs 280% in the placebo group; p<0.02) at 12 months. The absolute and percent increase in pain-free walking distance (PFWD) was greater in the PXF group (p<0.05). Treatment was well tolerated. No serious drug-related side effects were observed. Microcirculatory evaluation indicated an increase in flux (p < 0.05) in the PXF group (not significant in the placebo group); the after-exercise flux (AEF) was increased (p<0.05) in both groups at 6 months but the increase in AEF was greater in the PXF group at 12 month. In conclusion, between-group analysis favors PXF considering walking distance and microcirculatory parameters. Results indicate good efficacy and tolerability.

Postprandial rest pain and claudication of the lower extremity: A case report.

Postprandial rest pain and claudication in the lower extremities may occur in arteriosclerotic aortic occlusion when mesenteric and systemic collateral pathways provide inadequate blood flow to the extremity. The symptoms occur as a result of vasodilation of the distal mesenteric vascular bed with a concomitant increase in mesenteric blood flow which leads to a decrease in mesenteric artery to extremity collateral blood flow. This normal physiologic phenomenon, increase in mesenteric blood flow, causes the extremity pain. Such symptoms indicate a quite significant decrease in blood flow to the extremity, and prompt surgical correction is indicated. Aortofemoral reconstruction yields total reflief of the symptom complex.

Intermittent claudication unmasking underlying Fabry's disease.

In a 53-year-old woman, admitted to our Department with leg pain, peripheral arterial occlusive disease (PAOD) was diagnosed. The absence of cardiovascular risk factors in this middle-aged woman, the unexplained burning pain during both effort and rest of the lower extremities mimicking severe ischemia, decreased sweating and cold induced Raynaud's phenomenon raised the suspicion of an underlying predisposing disease. The coexistence of painful acroparesthesias, angiokeratomas, left ventricular hypertrophy (LVH), corneal opacities and lenticular lesions suggested the diagnosis of Fabry's disease, which was confirmed by low serum levels of a-galactosidase-A activity. This case, presented with intermittent claudication due to generalized atherosclerosis, is quite unusual, since Fabry's disease rarely produces symptoms in female carriers.

[Validation of a French translation of the Edinburgh claudication questionnaire among general practitioners' patients].

OBJECTIVES: Intermittent claudication is one of the clinical symptoms of peripheral arterial disease (PAD). The presence of PAD is a high risk marker of cardiac events and stroke. The PAD screening can be enhanced by the use of questionnaires. The Edinburgh Questionnaire presents in its English version better diagnostic performances compared to the Rose (WHO) Questionnaire. The aim of this study is to precise the performances of the French version of the Edinburgh Questionnaire among a population consulting general practitioners. METHODS: Four centers instructed 10 general practitioners each to the measurement of ankle pressure with a Doppler stethoscope. The physicians administrated the Questionnaire to 10 consecutive consultants in a same day, and measured the pressure on posterior tibial, dorsalis pedis and humeral arteries. With a second questionnaire they collected data concerning age, weight, height, and the presence of major risk factors. The same protocol was repeated a second day on new patients. The diagnosis of PAD was based on an ankle-arm index lower than 0.85 for at least on limb. RESULTS: The population studied consisted of 727 subjects (351 females and 376 males). The mean age was at 58.3 +/- 16.1 years (ranging from 18 to 83.3 years). The sensitivity of the Questionnaire is at 47% (95% CI: 32.3-61.7%), the specificity at 98.8% (95% CI: 97.5-99.4%), the positive and negative predictive values are respectively at 73.3% (95% CI: 54.1-87.7%) and 94.8% (95% CI: 94.7-97.6%). Among this population of general practitioners consultants, the prevalence of a low ankle-arm index under 0.85 is at 6.7%. DISCUSSION: The French version of the Edinburgh Questionnaire maintains the very good specificity of the English version. The lower sensitivity could be explained by the choice of the gold standard, namely the ankle-arm index which includes asymptomatic patients with authentic PAD. The use of this Questionnaire can be recommended for the screening of this disease as well as in epidemiological studies.

Management of patients with intermittent claudication.

Intermittent claudication, the most common symptomatology of peripheral arterial disease, is characterised by lower-extremity discomfort induced by exercise and relieved by rest. The most serious potential outcome of the condition is increased morbidity and mortality from cardiovascular disease, with which it is often associated, thus prompt diagnosis and management are crucial. Therapy consists of structured exercise and reduction of cardiovascular risk factors, followed by or together with pharmacological interventions with anticlaudicants (cilostazol or pentoxifylline) and specific antiplatelet agents (aspirin, clopidogrel). Revascularisation procedures are indicated in those with limb-threatening or lifestyle disabling disease.

[Treatment of severe intermittent claudication: ORACLE-PGE1 short term study. A randomised 40-week study. Evaluation of efficacy and costs].

BACKGROUND: The efficacy and cost of prostaglandin E1 (PGE1) in severe intermittent claudication was studied comparing a long-term protocol (LTP) with a short-term protocol (STP) in a randomised 40-week study. METHODS: Phase 1 was a 2-week run-in phase (no treatment) for both protocols. In LTP, phase 2 was the main treatment phase. Treatment was performed with 2-hour infusions (60 micro g PGE1, 5 days each week for 4 weeks. In phase 3 (4-week interval period), PGE1 was administered twice a week (same dosage). In phase 4 (40 weeks), no PGE1 were used. In STP, phase 2 treatment was performed in two days by a 2-hour infusion (60 micro g PGE1 twice a day in 2 days). The same cycle was repeated every 4 weeks. A treadmill test was performed at inclusion, at the beginning of each phase and at the end of weeks 12, 16, 20 32 and 40. A progressive training plan (walking) and reduction in risk factors plan was used in both groups. RESULTS: Out of the 1276 included patients 1165 completed the study (606 in LTP group; 559 in the STP). Drop-outs were 111. The two groups were comparable in distribution, risk factors and smoking. Intention-to-treat analysis indicated an increase in pain free walking distance (PFWD). The absolute and percent increase in pain-free walking distance (PFWD) was comparable in both LTP and STP groups with a significative increase in TWD at 4 weeks. At 20 and 40 weeks increase was up to 219% in the LTP and 460% in the STP group (p<0.02). Comparable results concerning PFWD were obtained in the two groups. Both treatments were well tolerated. No side effect was observed. Local effects were observed in 8.5% of the treated subjects in the LTP and 4% in the STP. The average cost of the LTP protocol was 8786 Euro. For STP the costs was 946 (10.8% of LTP). For both protocols the cost of the infusion was 24% of the total for the LTP and 35% in the STP. Therefore 75% of the cost is not drug-related. CONCLUSIONS: In conclusion between-group-analysis favours STP considering walking distance and costs. Results indicate good efficacy and tolerability of PGE1 treatment particularly STP.

[Intermittent claudication in a young patient. A case of isolated fibromuscular dysplasia of the external iliac artery].

Effort-linked intermittent claudication of arterial origin in sportsmen is often attributed to endofibrosis of the external iliac artery. Some knowledge of possible differential diagnoses, in particular the fibrodysplasia, is of importance regarding the therapy involved. Angioplasty treatment of external iliac endofibrosis may be controversial. However, the same does not apply to fibrodysplasia angioplasty, particularly if the latter is accomplished by inserting an endoprothesis. A case of fibromuscular dysplasia of external iliac artery in a 37 year old woman, treated with endoluminal angioplasty and stent, is reported.

[Lipoprotein(a) and Apo-A isoforms in patients with intermittent claudication].

AIM: To study a correlation between lipoprotein(a) [LP(a)], as well as the phenotype of apoprotein(a) [apo(a)] and the presence of intermittent claudication (IC). MATERIALS AND METHODS: The study included 25 patients (9 females, 16 males; mean age, 63.4 +/- 8.2 years) and 50 individuals (21 females, 29 males; mean age, 61.3 +/- 6.1 years) of a control group. RESULTS: In the patients, the level of LP(a) was 3 times higher than in the controls (median 39 and 13 mg/dl, respectively; p < 0.01). The low molecular-weight phenotypes of apo(a) occurred significantly more frequently in the patients than those in the controls (62 and 28%, respectively; p = 0.02). CONCLUSION: Multifactorial analysis has shown that the level of Lp(a) is an independent and important factor associated with the presence of IC.

Baastrup's disease as a cause of neurogenic claudication: a case report.

STUDY DESIGN: A rare case of Baastrup's disease as a cause of spinal canal stenosis in a patient with double-level spondylolisthesis is reported. OBJECTIVES: To report an intraspinal synovial cyst as an extension of neoarthrosis of Baastrup's disease causing spinal canal stenosis, and to review the relevant literature. SUMMARY OF BACKGROUND DATA: Baastrup's disease, more commonly known as kissing spines, has been implicated as a cause for low back pain. Neoarthrosis between the spinous processes has been described, but this is the first report in the literature of an extension of the synovial cavity to the intraspinal space resulting in extradural compression. METHODS: A 50-year-old woman with double-level spondylolisthesis and symptoms of instability and neurogenic claudication was evaluated and treated using spinal decompression and fusion. RESULTS: Radiographs showed a double-level spondylolisthesis at L3-L4 and L4-L5 levels, and magnetic resonance imaging showed the presence of a neocyst formation in the interspinous region and another cyst in the posterior epidural space at the same level causing dural compression. There was a suggestion of continuity between the two cysts that was confirmed at surgery. The neoarthrosis and the cyst were excised, and spinal decompression and fusion were performed. The patient had good relief of symptoms. CONCLUSIONS: Baastrup's disease leading to neoarthrosis formation with synovial cavity and causing low back pain has been reported previously. The cyst can enter into the epidural space through the midline cleft of the ligamentum flavum to result in extradural compression.

Hip pain caused by buttock claudication. Relief of symptoms by transluminal angioplasty.

Two patients with severe hip pain proved to have buttock claudication resulting from isolated stenosis of the hypogastric artery. This diagnosis may be elusive if distal pulses are palpable, directing the clinician's suspicion away from vascular pathology. Diagnosis requires angiography. The patients were successfully treated by transluminal angioplasty. Angioplasty is the initial treatment of choice for these patients because the hypogastric artery is usually readily and safely accessible from either the femoral or axillary artery.

Exercise: the best therapy for intermittent claudication?

The prophylactic value of physical activity for arteriosclerotic diseases is generally accepted. Regular exercise is also the most effective therapy for intermittent claudication although drug treatment is more popular in general practice. Recent findings show that exercise and drug treatments complement each other.

[Principle of treatment of intermittent claudication due to arteriosclerosis obliterans--reconstruction or conservative treatment].

MATERIALS AND METHODS: Two hundred and one patients of arteriosclerosis obliterans (ASO) with intermittent claudication (IC) were studied. Improvement of IC, score of return to social life, change of life condition and prognosis were compared between the two groups of reconstructive and conservative treatment. RESULTS: Improvement of IC was seen in 88.0% of the patients in the group of reconstruction and only 30.4% in the conservative treatment group. In the reconstructive group, the score of return to social life improved from 2.10 to 1.31 and the score of life condition also improved from 2.71 to 1.66. However in the conservative treatment group these score showed no significant improvement. Moreover the long term mortality rate was lower in the treatment group of reconstruction. CONCLUSION: The arterial reconstruction for IC is significant for improving the quality of life and exerts a favorable effect on life prognosis.

[Indication and results of surgical treatment of intermittent claudication].

In order to clarify the propriety of surgical treatment for intermittent claudication caused by arteriosclerosis obliterans (ASO), indication for vascular reconstruction and efficacy of surgery on patient's quality of life were investigated. Bypass surgery or laser angioplasty (PTLA) was undertaken in 149 of 188 ASO patients. Because of high risk factors (renal failure, ischemic heart disease, cerebro-vascular disturbance or malignant tumor), 39 patients were treated conservatively. Intellectual dysfunction in aged patient was evaluated by Okabe's brief mental scale test. Coronary artery disease was revealed by coronary angiography performed next to routine dipyridamole-loaded ECG in 19 to 78 patients. CABG or PTCA was performed prior to peripheral vascular reconstruction in 3 patients with serious coronary disease. Extra-anatomical bypass or PTLA was indicated mainly in patients with coronary artery disease or intellectual dysfunction. The anatomical bypass and the extra-anatomical bypass were undertaken in 88 and 61 patients respectively. Graft occlusion was observed in 8 cases. Patency rate of the anatomical bypass was 96.6% and that of the extra-anatomical bypass was 91.8%, at 32 months of postoperative mean follow-up period. The operative mortality rate was 2.7%. There was no major amputation due to graft occlusion.

Hematocrit dependent changes of muscle tissue oxygen supply in the lower limb muscle of patients with intermittent claudication.

Hematocrit dependent changes of muscle tissue oxygen supply at rest and after exercise were detected in 23 patients with chronical arterial occlusive disease stage IIb according to Fontaine. In these patients with a concomitant high hematocrit a stepwise isovolemic hemodilution by vena esection and subsequent infusion of 10% hydroxyethylstarch solution (200/0.5%) was achieved intraindividually. Measurements of muscle tissue oxygen pressure (pO2) values in the lower limb muscle using a standardized pedalergometric exercise test as well as pain free walking distance with a treadmill were performed. Improvement of muscle tissue pO2 supply after pedalergometric exercise as well as muscular performance on the treadmill were found at an average hematocrit value of 40.50%, whereas muscle tissue oxygen supply and pedalergometric performance were markedly reduced at hematocrit 50.60% as well as 33.75%. Thus it is likely that an improvement of muscle tissue oxygen supply in severe intermittent claudication can be achieved by isovolemic hemodilution to hematocrit values about 40-41%.

[Bilateral brachial claudication as the initial manifestation of giant cell arteritis. Case report and review of the literature].

A 69-year-old woman presented with bilateral arm claudication caused by segmental occlusions of both brachial arteries. Bilateral retrograde ring-desobliteration resulted in restauration of full pulses. Microscopic examination of the resected specimen revealed giant cell arteritis. No other manifestations of the disease could be detected. At autopsy affection of the aortic arch and of the arm arteries is found in about 70% of patients with giant cell arterities. Symptoms occur in only about 5% of them. Arterial stenoses are successfully treated with corticosteroids. In case of chronic occlusion, however, ischemia-induced symptoms may necessitate an operation. Endarterectomy (i.e. total dissection of the destroyed inner arterial wall layers) should be preferred to bypass procedures. Subsequent long-term corticosteroid therapy should be instituted in order to treat the underlying disease, and to prevent reocclusions.

Intermittent claudication in a professional rugby player.

Intermittent claudication in a professional rugby player is described. The typical features of a delayed and difficult diagnosis of an external iliac artery stenosis were found. The noninvasive diagnostic protocol used to investigate this young patient with a minimal arterial lesion enabled accurate localization and angioplasty to be performed at the same time as diagnostic angiography. The patient was symptom free with normal arterial pressures on follow-up. It is suggested that appropriate noninvasive investigations should be performed before angiography in young people with minimal lesions.
