A comparison study of self-expandable stents vs balloon angioplasty alone in femoropopliteal artery occlusions.

In a group of 26 patients percutaneous transluminal (balloon) angioplasty (PTA) and stents (Wallstents) were applied and in another 26 matched patients PTA alone was used as primary treatment for femoropopliteal occlusions of 3 cm or longer. Five patients with stents showed early thrombosis necessitating catheter thrombolysis and/or thrombus aspiration. Ten patients had recurrent stenoses within 12 months, mostly due to neointimal hyperplasia. Following three late catheter reinterventions, a cumulative secondary patency rate of 69% was achieved after 12 months. The group of patients treated by PTA alone showed a 12 months patency rate of 65% without reinterventions. In 8 other patients, stents were inserted for recurrent obstructive or PTA-resistant lesions, and similar results as with the stents above were obtained. Thus, these stents do not improve primary results of PTA in femoropopliteal occlusions but may be useful secondarily after unsuccessful PTA.

Angioplasty of the terminal aorta: follow-up of 20 patients treated by PTA or PTA with stents.

Twenty patients with distal aortic stenosis were treated by PTA for intermittent claudication and, in 3, 'blue toe' syndrome. Additionally, a self-expandable endoprosthesis (stent) was inserted into the aorta in three of the patients. The overall primary success rate (including those with a stent) was 100% with all patients becoming free of symptoms. Mean arm-ankle pressure difference decreased from 48 mmHg to 9 mmHg (P less than 0.01). During a median follow-up period of 15 months no patient had recurrence of claudication, embolism, or deterioration of the non-invasive parameters. Thus, PTA seems suitable for treating stenoses of the abdominal aorta, even in the presence of distal microembolization. Balloon dilatation, with the addition of stents in resistant cases, offers a valuable alternative to surgery in distal aortic stenosis.

Iliac graft access to facilitate endovascular repair of a ruptured thoracic aortic aneurysm -- a case report.

Arterial access for endovascular aortic aneurysm repair is usually gained through a common femoral artery approach. In small femoral arteries this can be difficult or even impossible owing to the large size of the introduction sheath of the delivery system. In such cases the iliac arteries or the abdominal aorta can be used for vascular access, although, in heavily calcified arteries,even this can be hazardous. The authors report an 81-year-old woman with a contained rupture of the thoracic aorta in whom a polyester graft was used to facilitate vascular access to the common iliac artery for a safe two-stage endovascular repair of the aneurysm.
