[Interventional procedures in patients after vascular reconstructive surgery of the lower extremities].

This study reports the results and complications of local thrombolysis therapy of recently occluded grafts manifested by acute ischemia in comparison with transluminal angioplasty of graft stenoses. Stenoses were diagnosed by means of ultrasound (asymptomatic patients) or manifested by claudications. The aim of our study is to emphasize the difference between efficacy of these two kinds of treatment and their difficulties.

[Revascularization of the aortoiliac arteries using stents].

The authors summarised their three year experience with endovascular treatment of the aortoiliac artery obstructive lesions using stents and transluminal angioplasty. Fifty-seven patients (61 limbs) underwent stent implantation to treat claudications (n = 50 limbs), rest pain (n = 6), non-healing defects (n = 4) and one patient was asymptomatic (n = 1). After stent placement patients were followed-up using clinical and duplex ultrasound examinations at 3 months and 6 months thereafter.

[Transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of symptomatic portal hypertension].

Background: A transjugular intrahepatic portosystemic shunt (TIPS) is the creation of a percutaneous portosystemic anastomosis which is used as an alternative method of surgical portosystemic shunts and endoscopic treatment in the therapy of complications of portal hypertension. The objective of the present work was to summarize experience with TIPS in 100 patients.

Methods And Results: In 1992-1995 the authors treated 100 patients with symptomatic portal hypertension by TIPS.

[Transjugular intrahepatic portosystemic shunt].

The transjugular intrahepatic portosystemic shunt (TIPS) is a relatively new method of creating a portosystemic shunt using a needle, angioplasty balloon catheters and expandable metallic stents. During a 6-month period, the authors have performed TIPS, using the spiral Z-stent--another modification of the Gianturco-Rósch stent--in 13 patients with portal hypertension. The procedure was technically successful in all patients.
