Endovascular gamma irradiation for the prevention restenosis after angioplasty of femoropopliteal de novo stenoses.

The purpose of this study was to investigate the effectiveness and detect side effects of centered, overlapped endovascular gamma irradiation after angioplasty of de novo femoropopliteal stenoses. Thirty patients (age 65.3+/-9.

Postcatheterization pseudoaneurysm: results of US-guided percutaneous thrombin injection in 240 patients.

Purpose: To prospectively evaluate ultrasonographically (US) guided percutaneous thrombin injection for treatment of femoral artery and brachial artery pseudoaneurysms.

Materials And Methods: The university institutional review board approved the study. Informed consent was obtained from all patients.

De novo femoropopliteal stenoses: endovascular gamma irradiation following angioplasty--angiographic and clinical follow-up in a prospective randomized controlled trial.

Purpose: To assess and report the follow-up results of a randomized controlled trial on centered endovascular gamma irradiation performed after percutaneous transluminal angioplasty (PTA) for de novo femoropopliteal stenoses.

Materials And Methods: Thirty patients who underwent PTA for de novo femoropopliteal stenoses were randomly assigned to undergo 14-Gy centered endovascular irradiation (irradiation group, n = 15) or no irradiation (control group, n = 15). Intraarterial angiography was performed 6, 12, and 24 months after treatment; duplex ultrasonography (US), the day before and after PTA and 1, 3, 6, 9, 12, 18, and 24 months later.

Femoral pseudoaneurysms: management with percutaneous thrombin injections--success rates and effects on systemic coagulation.

Purpose: To determine the success rate of percutaneous ultrasonographically (US) guided thrombin injection in the treatment of femoral pseudoaneurysms and to evaluate the effects of thrombin injection on systemic coagulation parameters.

Materials And Methods: Fifty femoral pseudoaneurysms (37 simple pseudoaneurysms with one lobe and 13 complex pseudoaneurysms with two or three lobes) were treated with US-guided percutaneous thrombin injections. Pseudoaneurysm size, neck length and width, thrombin dose, outcome of therapy, and complications were documented prospectively.
