Morbidity after procurement of radial arteries in diabetic patients and the elderly undergoing coronary revascularization.

BACKGROUND: The use of radial arteries for coronary revascularization is increasing. There remain concerns regarding alteration of upper extremity function after radial artery procurement. This study evaluates the functional morbidity in higher risk patients. METHODS: Between April 1997 and September 1999, 374 patients underwent unilateral or bilateral radial artery procurement. A questionnaire was used to evaluate symptoms related to motor and sensory function and changes in appearance after radial artery harvest. RESULTS: Two hundred eighty-nine patients were successfully interviewed. The average age was 63 years. Median follow-up was 9.5 months (range, 2 to 23 months). No patient suffered limb loss. Altered gross and fine motor function, residual pain, paresthesias, numbness, pallor, swelling, and altered temperature sensation were compared among diabetic patients, patients older than 70 years, and patients without these characteristics. CONCLUSIONS: Radial artery procurement for elective coronary revascularization can be done with minimal serious morbidity in higher risk patients. The most common symptoms were numbness and paresthesia. Despite the finding of greater residual pain in diabetic patients, we do not believe the use of radial artery conduits is contraindicated in these patients.

Endoscopic radial artery harvesting: results of first 300 patients.

BACKGROUND: With the expanded use of the radial artery as a bypass conduit in patients undergoing coronary artery bypass grafting, an endoscopic radial artery harvesting method was used to improve esthetics and patient acceptance, and possibly, to decrease hand neurologic complications. METHODS: After informed consent and confirmation of adequate ulnar collateral blood flow, 300 consecutive patients undergoing coronary artery bypass grafting had their nondominant radial artery endoscopically removed through a small 3-cm incision just proximal to the radial styloid prominence. Standard endoscopic vein equipment (30-degree 5-mm endoscope, subcutaneous retractor, and vessel dissector) with ultrasonic harmonic coagulating shears were used. After radial artery isolation, the radial artery was proximally clipped and transected 1 to 2 cm distal to the visualized ulnar artery origin to the inferior end of the wrist incision. RESULTS: The mean age was 62.2 years; 23% of the patients were women, 39% had diabetes mellitus, and 28% had peripheral vascular disease. All 300 endoscopic radial arteries were grossly acceptable and used for grafting. Early in the series, 29 patients (9.7%) required a second 3-cm incision proximally for vascular control. Only one wrist incision was required at the last 200 cases. The conduit length varied between 18 and 24 cm. Occurring early in the series, hospital complications were two tunnel hematomas requiring drainage and one brachial artery clipping repaired primarily without sequela. At 30 days postoperative follow-up, 5 patients (1.6%) had been treated with oral antibiotics for incisional cellulitis and 26 patients (8.7%) had objective dorsal thenar sensory numbness. No ischemic hand complication, perioperative myocardial infarction, reintervention in radial artery graft distribution, or numbness in the lateral forearm occurred. All patients expressed marked satisfaction with the small incision and cosmetic result. CONCLUSIONS: In our initial experience, endoscopic radial artery harvesting can be performed safely, with minor, infrequent complications. A full-length radial artery conduit can be obtained with improved esthetics and patient satisfaction and acceptance. Late dorsal thenar paresthesias, although infrequent, continue to be a problem as with the open method.

Lumbar-sacral radiculopathy secondary to intraspinal synovial cyst.

OBJECTIVE: The presentation of a patient with acute low back pain and distal radiation to the lower extremities is often attributed to a herniated nucleus pulposus (NHP). The purpose of this report is to illustrate how an intraspinal lumbar synovial cyst can have a similar presentation. CASE PRESENTATION: A 52-year-old man presented with low back pain with left lower extremity weakness and distal radiation. An electrodiagnostic evaluation was consistent with lumbar-sacral radiculopathy. Computed tomography and magnetic resonance imaging showed a synovial cyst of the L4-5 facet joint. INTERVENTION: The patient underwent a L4-L5 laminotomy, synovial cyst excision, and decompression of the L5 nerve root. RESULTS: There were no postoperative complications. The patient had residual left lower extremity numbness but gradually regained the strength of his left lower extremity. Intraspinal synovial cyst can mimic the clinical pattern of NHP. CONCLUSION: An intraspinal lumbar synovial cyst can present with symptoms of nerve root compression. Given the presentation of lumbar-sacral radicular symptoms such as radiating pain, muscle weakness, and numbness, surgical excision of the lumbar synovial cyst remains the definitive treatment of choice.

Vest restraint palsy.

OBJECTIVE: Evaluate by electrophysiologic methods the cause of arm weakness and numbness in an agitated patient who struggled against a vest restraint garment. CASE PRESENTATION: An agitated patient with encephalitis required vest restraint and developed bilateral numbness of hands and weakness of distal upper extremity muscles. He was of thin stature and had abrasions in the axilla from the restraint straps. Routine nerve conduction and needle electromyographic needle studies were used to document bilateral conduction block of ulnar and median nerves between the elbow and Erb's point with minimal denervation. INTERVENTION: After identification of the vest restraint as the cause of neuropraxic palsies, adjustments were made to the vest straps. RESULTS: The symptoms and clinical signs began to resolve with adjustment of the vest restraint straps and completely resolved after the patient was no longer encephalopathic and was discharged from the hospital. CONCLUSIONS: Compressive nerve lesions in the axilla should be recognized as a potential complication of vest restraint, especially in combative patients.

Meralgia paresthetica secondary to limb length discrepancy: case report.

Meralgia paresthetica consists of pain and dysthesia in the lateral thigh caused by entrapment of the lateral femoral cutaneous nerve (L2-L3) underneath the inguinal ligament. Abdominal distension, tight clothing, and hip hyperextension are all described causes of this condition. To our knowledge this has never been attributed to a limb length discrepancy. We present a 51-year-old man with a long-standing history of right sided meralgia paresthetica. History and physical and radiological examination were unrewarding except that his left leg was shorter than the right by 2 cm. Nerve conduction studies of the lateral femoral cutaneous nerve on the left had a normal latency and amplitude but were absent on the right. To prove the hpothesis that the limb length discrepancy was responsible for the condition, a single subject study was performed. The presence or absence of pain and dysesthesia in the right thigh was the observed behavior. Intervention consisted of wearing a 1.5-cm lift in the left or right shoe for 2 weeks each with an intervening 2-week lift-free period. Pain was recorded on a numeric scale and numbness as being present or absent. There was continuing pain without and with the lift in the right shoe but no pain or numbness with the lift in left shoe. It was concluded that the limb length discrepancy was responsible for the meralgia paresthetica. Pertinent literature and possible pathomechanics are discussed.

Emotional response at the time of a potentially traumatizing event and PTSD symptomatology: a preliminary retrospective analysis of the DSM-IV Criterion A-2.

DSM-IV added an emotional response component to the definition of Criterion A for PTSD. The present study investigated the relationship between retrospective reports of emotional responses (fear, helplessness, and horror) and disrupted emotional responses ("numbing") at the time of a potentially traumatizing event and reports of PTSD symptomatology among undergraduate participants. We found that, of the DSM-IV criteria, only helplessness was significantly correlated with post-traumatic symptomatology. Reports of peritraumatic emotional numbing uniquely predicted subsequent PTSD symptomatology beyond coincident emotional responses, suggesting that further research is needed to explore the various dimensions of peritraumatic emotional response relevant to the development of PTSD.

Results of combined Nesbit penile plication with plaque incision and placement of Dacron patch in patients with severe Peyronie's disease.

We treated 9 men with severe curvature of the penis secondary to Peyronie's disease with penile plication and a previously unreported technique of incision of the Peyronie plaque and placement of Dacron patch. All men were potent before penile straightening. At a mean followup of 17.5 months all men achieved good to excellent correction of the deformity and they have remained potent. One patient initially complained of numbness of the glans penis and decreased penile rigidity distal to the Dacron patch but potency returned and the numbness resolved.

Clinical outcomes in patients with Chiari I malformation: a review of 27 cases.

BACKGROUND: Chiari I malformation is a congenital maldevelopment defined as downward herniation of the cerebellar tonsils through the foramen magnum. It has been treated using a variety of surgical procedures. Surgical outcomes have been reported with varying results throughout the literature. METHODS: We retrospectively reviewed 27 patients with Chiari I malformation operated at the University Hospital during a 9-year period from 1988 to 1997. We assessed preoperative and postoperative signs and symptoms in all the patients including headache, neck pain, nystagmus, vertigo, weakness, spasticity, atrophy, numbness, pain and temperature dissociation, diplopia, dysphagia, and sphincter dysfunction. Each patient was analyzed to determine if there was an arrest in the progression of the disease after surgical intervention. RESULTS: Syringomyelia was present in 59% of the patients. Only 1 patient who presented with neck pain improved. One patient reported new onset headache, and one patient described his headache resolved. Vertigo resolved in three patients; two patients stated mild improvement, and one patient reported worsening. Nystagmus improved or resolved in six patients. Weakness improved in only two patients who did not have syringomyelia. Dysphagia improved in two patients, and in the others it remained unchanged. Diplopia, spasticity, atrophy, and numbness remained unchanged. CONCLUSIONS: Our study provides evidence that the main benefit of the surgical management in patients with Chiari I malformation with or without syringomyelia is to arrest the progression of the disease.

Percutaneous trigeminal ganglion balloon compression for treatment of trigeminal neuralgia, part II: results related to compression duration.

OBJECTIVE: The purpose of this study is to find out how different compression time affects the results of percutaneous trigeminal ganglion compression for treatment of trigeminal neuralgia. METHODS: This study includes 80 patients with intractable third-branch trigeminal (V3) neuralgia who had received percutanious trigeminal ganglion balloon compression. All the patients received some treatment protocol except for the duration of compression. Group 1 patients received 60-second and group 2 patients received 180-second compression. A computerized pressure recording system was used for pressure monitoring and analysis. RESULTS: Both groups had 100% immediate pain relief and all patients experienced mastication weakness immediately after the procedure. The facial numbness was severe in group 2 in the first trigeminal (V1) distribution (p<0.05) but not in the second or third trigeminal (V2,3) distribution (p>0.05) in the immediate period after the operation. The recurrence rate in the first year follow-up was higher in group 1 (5%) than in group 2 (2.5%) but did not reach the statistical difference (p>0.05). At 1 year follow-up after the procedure, group 1 and lower incidence of facial numbness over all trigeminal distribution (V1,2,3) than group 2 (p<0.05) mastication weakness all recovered during the first-year follow up. CONCLUSIONS: With accurate monitoring of the balloon pressure during the percutaneous trigeminal ganglion compression, it was found that the shorter duration of compression had less side effect. At one year follow-up, the incidence of recurrrence rate was slightly higher in the patients who received 60-second compressions than in those who received 180-second compressions, but there was no significant statistical difference. Whether patients with first or second branch of trigeminal neuralgia require longer compression duration needs further study.

Hypertrophied cauda equina presenting as intradural mass: case report and review of literature.

BACKGROUND: Hereditary motor and sensory neuropathy types I and III usually lead to enlargement of peripheral nerves. Rarely, spinal nerve roots may also be involved, leading to radiculopathy and/or myelopathy. METHODS: This 44-year-old man with back and lower extremity radicular pain and distal lower extremity weakness and numbness was found to have a nonenhancing intradural mass that caused a nearly complete myelographic block from L1-L4. He underwent a decompressive laminectomy with intradural exploration. RESULTS: Hypertrophic but otherwise normal-looking nerve roots were observed. Subsequent electrodiagnostic testing and sural nerve biopsy confirmed that this patient had a previously unsuspected hereditary motor and sensory neuropathy (HMSN). His pain resolved, but at latest follow-up his weakness and numbness persisted. CONCLUSIONS: Nonenhancing spinal intradural mass lesions may represent enlarged nerve roots, which have a number of potential etiologies. Electrodiagnostic studies and peripheral nerve biopsy are instrumental in establishing the diagnosis of HMSN.

Minimizing upper lip and incisor teeth paresthesias in approaches to transsphenoidal surgery.

Currently popular transsphenoidal approaches to the pituitary include sublabial, external rhinoplasty, alotomy, and transnasal techniques. The conventional sublabial approach remains the workhorse method despite postoperative lip edema, potential difficulty for denture wearers, and troublesome persistent upper lip and incisor teeth numbness. We traced the courses of the nasopalatine, infraorbital, and anterior superior alveolar nerves in 41 cadaveric half-head dissection to determine the exact contribution to upper lip and incisor teeth innervation. We then conducted a retrospective patient survey of 25 sublabial, 28 external rhinoplasty, 23 alotomy, and 12 transnasal approaches to the hypophysis to assess the incidence of upper lip and incisor teeth paresthesias lasting longer than 1 month. We conclude that rhinoplastic techniques are superior to the sublabial approach in limiting upper lip and incisor teeth numbness without compromising neurosurgical exposure for hypophysectomy.

Neurotologic follow-up after radiation of posterior fossa tumors.

OBJECTIVE: Stereotactic radiation treatment, also known as gamma knife surgery or radiosurgery, has come into acceptance as a treatment alternative to surgical removal for posterior fossa tumors. The purpose of this article is to describe the role of the neurotologist in the optimal management of neurotologic complications after stereotactic radiation, as illustrated by five patients. STUDY DESIGN: Retrospective chart review. PATIENTS: Five patients who underwent stereotactic radiation of posterior fossa tumors. MAIN OUTCOME MEASURES: Presence or absence of neurotologic complications (tumor growth, hearing loss, imbalance/ataxia, vertigo, and facial paralysis) or neurosurgical complaints (facial numbness, motor weakness, headache, hydrocephalus, and subarachnoid cysts). RESULTS: Postradiation neurotologic complaints included vertigo, imbalance/ataxia, and progressive hearing loss in four of the five patients. Continued tumor growth occurred in two patients; two patients had no growth; in one patient the tumor became smaller. The complications of facial nerve paralysis, facial numbness, motor weakness, headache, hydrocephalus, cerebellar edema, and posterior fossa arachnoid cyst formation occurred less frequently. CONCLUSIONS: Stereotactic radiation of posterior fossa tumors can produce significant neurotologic problems. It is imperative that neurotologists remain involved in the follow-up care of patients with posterior fossa tumors to offer optimal treatment alternatives for the neurotologic disorders.

Analysis of facial and trigeminal nerve function after arthroscopic surgery of the temporomandibular joint.

PURPOSE: This study analyzes facial and trigeminal nerver function after arthroscopic surgery. PATIENTS AND METHODS: Eighty-one consecutive patients (81 joints) who underwent unilateral temporomandibular joint (TMJ) arthroscopic surgery were assessed postoperatively for facial and trigeminal nerve function. RESULTS: Twenty-four of 81 patients (29.6%) had some degree of sensory or motor nerve dysfunction. Two patients (2.5%) showed signs of facial nerve dysfunction, which completely resolved in one patient in 11 weeks, but persisted mildly in the other at the 1-year follow-up examination. CONCLUSIONS: Auriculotemporal syndrome was not detected in any of the 40 patients tested. However, transient numbness over the distribution of the auriculotemporal nerve was present in 19 of 81 patients (23.4%). This numbness persisted for 3 days to 3 months with a mean duration of 14 days. Three of the 81 patients (3.6%) showed signs of inferior alveolar and lingual nerve involvement, which returned to normal in 4 to 12 weeks in all 3 patients.

Comparison of two techniques of dermal graft harvest for temporomandibular joint reconstruction.

PURPOSE: The purpose of our study was to compare the healing characteristics of two common techniques of obtaining a dermal graft and the patient's perception of the aesthetics of the donor site scar. MATERIALS AND METHODS: Fifty-two female patients (60 sites) were evaluated by means of questionnaire, interview, and chart review. The mean follow-up time was 4.08 years after temporomandibular joint reconstructive surgery. Comparisons were made between the two primary harvest techniques: the dermatome (trapdoor) and the elliptical excision methods. Of the 60 sites, 32 involved the elliptical method and 28 the trapdoor method. RESULTS: Common findings in both groups included prolonged discomfort (6.6%), altered contour (50%), color change (58.3%), prolonged numbness (10%), and itching (21.6%). There were few healing complications (5.0%). Aesthetically, 45% of patients thought their scars were noticeable, and 8.3% thought that they were bothersome. The elliptical method showed significantly less discomfort, texture change, numbness, and itching. The scars were concealed better and less noticeable. Although 60.7% of the patients with the trapdoor method considered the wounds to be noticeable, only four patients reported that the scars were bothersome. CONCLUSIONS: Both techniques were used successfully with minimal complications. Although the elliptical technique appeared to have cosmetic advantages, larger grafts produced longer wounds, which may be more difficult to conceal. The trapdoor method is a simple technique that is used effectively with good patient acceptance. The results of this study are useful in properly informing patients about what to expect after having a dermal graft.

200 mg daily of lamotrigine has no analgesic effect in neuropathic pain: a randomised, double-blind, placebo controlled trial.

Anticonvulsant drugs are commonly used in neuropathic pain. There is anecdotal evidence of an analgesic effect of the anticonvulsant lamotrigine in neuropathic pain, but this is verified by few randomised controlled trials. This randomised, double-blind, placebo controlled trial of examined the effect of lamotrigine in a dose increasing to 200 mg in 100 patients with neuropathic pain. Eight patients failed to attend for review, 18 withdrew early and 74 provided results. There was no statistical difference in age, sex or duration pre-treatment pain in the two groups. Total pain, the character of the pain, sensitivity, numbness, paraesthesia, sleep, mobility, mood, quality of life and analgesic consumption were measured. There was a correlation between burning and numbness (P<0. 01), shooting pain and total pain (P<0.01) and between analgesic consumption and mobility (P<0.05) throughout the study period. There were no correlation between any other measured variable. There was no significant change in any variable measured over the eight week period when lamotrigine was used. It is concluded that at the dose used and using the dose escalation regime described, lamotrigine had no effect on either pain, component pain symptoms or quality of life variables.

Does increased nerve length within the treatment volume improve trigeminal neuralgia radiosurgery? A prospective double-blind, randomized study.

PURPOSE: To test the hypothesis that increasing the nerve length within the treatment volume for trigeminal neuralgia radiosurgery would improve pain relief. METHODS AND MATERIALS: Eighty-seven patients with typical trigeminal neuralgia were randomized to undergo retrogasserian gamma knife radiosurgery (75 Gy maximal dose with 4-mm diameter collimators) using either one (n = 44) or two (n = 43) isocenters. The median follow-up was 26 months (range 1-36). RESULTS: Pain relief was complete in 57 patients (45 without medication and 12 with low-dose medication), partial in 15, and minimal in another 15 patients. The actuarial rate of obtaining complete pain relief (with or without medication) was 67.7% +/- 5.1%. The pain relief was identical for one- and two-isocenter radiosurgery. Pain relapsed in 30 of 72 responding patients. Facial numbness and mild and severe paresthesias developed in 8, 5, and 1 two-isocenter patients vs. 3, 4, and 0 one-isocenter patients, respectively (p = 0.23). Improved pain relief correlated with younger age (p = 0.025) and fewer prior procedures (p = 0.039) and complications (numbness or paresthesias) correlated with the nerve length irradiated (p = 0.018). CONCLUSIONS: Increasing the treatment volume to include a longer nerve length for trigeminal neuralgia radiosurgery does not significantly improve pain relief but may increase complications.

Fractionated stereotactic radiotherapy for the treatment of vestibular schwannomas: combined experience of the Toronto-Sunnybrook Regional Cancer Centre and the Princess Margaret Hospital.

PURPOSE: To evaluate the efficacy and toxicity of fractionated stereotactic radiotherapy (FSRT) for vestibular schwannomas in patients treated at two university-affiliated hospitals. METHODS AND MATERIALS: Thirty-nine patients were treated between April 1996 and September 2000. The median age was 56 years (range: 29-80), and median maximal tumor diameter was 20 mm (range: 9-40). A total of 11 patients had fifth and/or seventh cranial nerve dysfunction before irradiation; 2 patients had only facial weakness, 5 patients had only facial numbness, and 4 patients had both facial weakness and numbness. Thirty-three patients were treated with primary FSRT, and 6 patients were treated for recurrent or persistent disease after previous surgery. All patients were treated with 6-MV photons using a stereotactic system with a relocatable frame. The 39 patients received 50 Gy in 25 fractions over 5 weeks. Median follow-up was 21.8 months (range: 4.4-49.6). RESULTS: Local control was achieved in 37 patients (95%). Two patients experienced deterioration of their symptoms at 3 and 20 months as a result of clinical progression in one case and tumor progression in the other and underwent surgery post FSRT. A total of 19/28 (67.9%) patients preserved serviceable hearing after FSRT. Deterioration of the facial and trigeminal nerves was observed in only 2 patients who were treated with surgery post FSRT. CONCLUSION: FSRT provided excellent tumor control with minimal morbidity and good hearing preservation in this cohort of patients. Longer follow-up is required to confirm long-term control rates.

Severe carpal tunnel syndrome potentially needing surgical treatment in a general population.

PURPOSE: To estimate the prevalence of severe carpal tunnel syndrome (CTS) that potentially needs surgical treatment in a general population. METHODS: A health-status questionnaire was mailed to a random general population sample of 3,000 subjects (ages, 25-74 y). The responders who reported numbness and/or tingling in the median nerve distribution in the hands were asked to attend a clinical evaluation at which they completed the validated CTS questionnaire and underwent physical examination and nerve conduction tests. The CTS questionnaire measures the severity of symptoms and disability on a scale from 1 (none) to 5 (most severe). The potential need for surgery was defined as CTS symptom severity score of 3.2 or greater or functional status score of 2.5 or greater (corresponding to median preoperative scores for surgical patients in previous reports). RESULTS: The response rate for the survey was 83%. Of the responders who reported numbness and/or tingling in the median nerve distribution in the hands 81% attended the clinical evaluation. Of the 94 subjects diagnosed with clinically certain CTS, 19 (20%; 12 with electrophysiologically proven median neuropathy) had previously undiagnosed CTS that potentially needed surgical treatment, yielding a population prevalence of 7 per 1,000 (95% confidence interval, 4-11 per 1,000). CONCLUSIONS: In a general population there was a 0.7% prevalence of undiagnosed CTS with a severity similar to that of patients undergoing surgery. The degree to which variable numbers of this group are drawn into a medical system could account for variations in the rate of surgery performed.
