A case of intracerebral and spinal vascular malformations in a patient without hereditary haemorrhagic telangiectasia is presented. The spinal vascular malformation was cryptic and its true nature was only revealed by MRI.

One hundred patients with mallet finger injuries were reviewed and examined three to five years after injury. Twenty nine patients still had symptoms consisting mainly of pain and cold intolerance. The degree of residual deformity, presence of a fracture, or delay in treatment were not related to symptoms.
Balloon-expandable, intraluminal stenting of the iliac arteries with the Palmaz stent was the subject of a multicenter study for 4 years. A total of 486 patients underwent 587 procedures. Four hundred and five patients had unilateral and 81 had bilateral iliac stent placements. Follow-up ranged from 1 to 48 months (mean 13.3 +/- 11 months). Sustained clinical benefit of the treated patients was obtained in 90.9% at 1 year, 84.1% at 2 years, and 68.6% at 43 months. Angiographic patency rate was 92%. Diabetes mellitus and poor runoff had significant negative influence on the clinical outcome. The 10% incidence of procedural complications was not altered by operator experience.
PURPOSE: To assess, in a multicenter setting, safety, technical results, and restenosis rate of the Palmaz stent for treatment of atherosclerotic ostial renal artery stenosis. METHODS: Ten centers enrolled 106 patients (120 treated renal artery stenoses) in the study. Patient selection was based on unsuccessful percutaneous transluminal renal angioplasty (residual stenosis >/= 20%) performed for treatment of ostial stenosis >/= 50%, in patients with hypertension and/or impaired renal function. Safety was assessed by means of the complication rate, and technical results by the number of successful stent placements and occurrence of restenosis (>50%) at intraarterial angiographic follow-up. RESULTS: Stent placement was successful (n = 112) or partially successful (n = 5) in 117 (98%) arteries. Complications occurred in 19 procedures; seven were of serious clinical significance. Angiographic follow-up was performed in 89 of 117 (76%) cases, at a mean of 8 months (range 2. 5-18 months). Fifteen stents (16.9%) showed restenosis (at a mean of 8.5 months), of which 10 were successfully redilated. CONCLUSION: Renal artery stenting has a high technical success rate, a complication rate comparable to percutaneous transluminal renal angioplasty, and a low rate of restenosis at 8 months angiographic follow-up.
PURPOSE: To demonstrate that proximal esophageal stenoses and tracheoesophageal fistulas can be adequately palliated with use of metallic stents without significant foreign-body sensation. MATERIALS AND METHODS: Between June 1994 and March 1999, 22 patients with lesions within 3 cm of the cricopharyngeus were treated by placement of metallic stents. The series was reviewed retrospectively. Twenty patients had surgically unresectable malignant lesions, two patients had benign disease. Ten patients had associated tracheoesophageal fistulas. In all, the upper limit of the stent was between C5 vertebral body inferior endplate and the T2 vertebral body superior endplate. The case-notes were reviewed until patient death (range, 6-198 days), or to date in the two surviving patients with benign disease. RESULTS: Immediate technical success was 93% (27 of 29). Dysphagia scores improved from a median of 3 to 2 after stent placement. Eighteen of 22 (82%) patients reported no foreign-body sensation. There have been no cases of proximal migration, periprocedural perforation, or deaths. The two patients with benign disease experienced significant complications. CONCLUSION: Lesions in proximity to the cricopharyngeus can be successfully palliated without significant foreign-body sensation in the majority of patients with use of metallic stents. The authors urge caution in placing stents in patients with benign disease.
