[Interventional angiography].

Percutaneous transluminal angioplasty (PTA) by balloon catheters is the standard method in interventional angiology. It is recommended in the aorto-iliac region for arterial stenoses, and in the femoro-popliteal arteries for stenoses and short occlusions. Due to progress in technology of catheters and guide wires, a primary success rate of more than 90% is to be expected with favorable angiographic conditions. The long-term patency rate of some 90% on the aorto-iliac level exceeds that of 70-90% on the femoro-popliteal level, with the patency rate decreasing with increasing complexity of the lesions. Subacute/acute occlusions of the femoro-popliteal arteries are treated successfully in 80% by catheter-thrombolysis and/or thrombus aspiration. Several new techniques are under clinical evaluation, such as laser angioplasty, rotational catheters, atherectomy catheters and stents. Their application in clinical routine has up to now not been justified except for special situations such as obtaining biopsy material by Simpson catheter or maintenance of patency in balloon resistant lesions by stents.

[Choleperitoneum following Kehr's T-tube removal: conservative treatment with culdocentesis associated with sphincterotomy and endoscopic drainage of the bile ducts].

The Authors present a case of bile peritonitis due to a biliary fistula developed after T tube removal from the common bile duct. Highlighting poor clinical manifestations they report an alternative conservative treatment, by drainage of the bile leakage with culdocenthesis and successive endoscopic spincterotomy and transpapillary drainage.

[Vascular endoprosthesis of femoro-popliteal occlusive disease].

A self-expanding vascular endoprosthesis (wall stent) was implanted in 26 patients with femoropopliteal occlusive disease following recurrent stenosis or occlusion after percutaneous angioplasty. Implantation was successful in all cases and there were no complications. Five of the 26 patients developed a thrombosis in the first nine days; in four of these, thrombolysis was successful. Patency rate after one month was 96%, after three months 95%, after six months 85% and after nine months 87%. In order to prevent thrombosis after implantation, anticoagulant therapy is indicated. Poor distal flow encourages intimal hyperplasia and therefore recurrences.
