PTA and stenting of benign venous stenoses in the pelvis: long-term results.

Purpose: To provide follow-up data on endovascular intervention for venous stenoses in the pelvis.

Methods: Between 1985 and 1995, 35 patients presented with 42 stenoses of the pelvic veins after operative thrombectomy and creation of an arteriovenous fistula, combined with intraoperative venous angioscopy. All patients underwent angioplasty and, if unsuccessful, percutaneous insertion of an endovascular stent (n = 7).

Purpose: Retrospective analysis of the results after infrapopliteal PTA of isolated crural limb artery stenoses in patients with critical crural limb ischaemia.

Patients And Methods: Between 1989 and 1994 70 infrapopliteal dilatations of isolated crural limb artery stenoses in 44 patients (47 PTA procedures) were done with small diameter balloon catheters. 45 patients were stage IV according to Fontaine's classification, two patients were stage III.

In a prospective study, the results following PTA of 30 short stenoses > 70% in 17 infrainguinal arterial bypass grafts were examined. The stenoses were detected after a mean follow-up of 7.2 months by Duplex-ultrasound.

[Percutaneous balloon dilatation of isolated lesions of the calf arteries in critical ischemia of the leg].

Between 1990 and 1993 we performed 42 percutaneous transluminal balloon angioplasties (PTA) in 30 patients with isolated lesions of crural arteries and limb threatening ischaemia. The average age of the patients was 70.5 years, 90% were diabetics.

Gas formation after renal artery embolisation: genesis and clinical relevance.

Preoperative embolisation of renal carcinomas has several pros and cons for the patient. The negative aspects can be summarized as 'post-infarction' syndrome'. Radiologically, intrarenal gas formation is always evident.
