Placement of hemoparin-coated stents in the iliac arteries: early experience and midterm results in 28 patients.

Purpose: Aim was to determine immediate results and mid-term outcome of the hemoparin-coated (HC) stainless-steel stent (camouflage coating) in the treatment of occlusive lesions of the iliac arteries.

Materials And Methods: Twenty-eight patients were prospectively treated with the use of a HC stent between January 2007 and March 2010. Clinical examination and color-doppler ultrasound were performed at 1, 3, 6 and 12 months, CT angiography (CTA) or MR angiography (MRA) at 12 months.

Secondary aortic dissection after endoluminal treatment of an intramural hematoma of the thoracoabdominal aorta: endovascular extension with two stent grafts and scarce distal landing.

Secondary dissection in the descending aorta after endovascular therapy may demand subsequent interventional procedures. This can set a particularly significant challenge for the endovascular specialist. When implanting an aortic prosthesis, a sufficient contact between the covered segment and the healthy vessel wall is advisable.

Covered stents in transjugular portosystemic shunt: healing response to non-porous ePTFE covered stent grafts with and without intraluminal irradiation.

The aim of this study was to evaluate the healing response to a new commercially available ePTFE-covered stent graft used to create transjugular intrahepatic portosystemic shunts (TIPS) in an animal model with and without intraluminal irradiation. The study was designed for ten domestic normotensive pigs. The TIPS was created using a ePTFE-covered stent graft (Viatorr, Gore, Flagstaff, Ariz.

Early experience and midterm follow-up results with a new, rotational thrombectomy catheter.

Purpose: To assess the efficacy and safety of the Rotarex rotational thrombectomy catheter in treating occlusions of the femoropopliteal arteries.

Methods: The Rotarex catheter (Straub Medical, Switzerland) is a rotational thrombectomy device which is supposed to be able to remove fresh and partially organized clot material from an acutely or subacutely occluded vessel. Nineteen limbs of 18 patients (10 women, 8 men; mean age 72.
