BACKGROUND AND PURPOSE Stent placement has been applied in small case series as a rescue therapy in combination with different thrombolytic agents, percutaneous balloon angioplasty (PTA), and mechanical thromboembolectomy (MT) in acute stroke treatment. These studies report a considerable mortality and a high rate of intracranial hemorrhages when(More)
PURPOSE The latest-generation Amplatzer vascular plug (AVP), the AVP 4, is designed for embolization of smaller vessels without a sheath or guiding catheter. This study evaluated the AVP 4 in peripheral vascular embolization. MATERIALS AND METHODS Embolization with the AVP 4 was attempted in 13 patients (11 men) for trauma (n = 7) and other indications (n(More)
PURPOSE To prospectively evaluate the midterm outcome after balloon angioplasty or surgical profundaplasty of the deep femoral artery (DFA) as an isolated procedure in chronic critical limb ischemia (CLI). METHODS Between 1995 and 2001, 21 limbs in 20 patients (mean age 77+/-8 years) were treated by revascularization of the deep femoral artery (DFA) as an(More)
The optimal management of patients with symptomatic severe ostial vertebral artery stenosis (OVAS) is currently unclear. We analyzed the long-term outcome of consecutive patients with OVAS who received either medical treatment (MT) or vertebral artery stenting (VAS). Thirty-nine (>70%) patients with severe OVAS were followed for a mean period of 2.8 years.(More)
Falsely high ankle-brachial index (ABI) values are associated with an adverse clinical outcome in diabetes mellitus. The aim of the present study was to verify whether such an association also exists in patients with chronic critical limb ischemia (CLI) with and without diabetes. A total of 229 patients (74 +/- 11 years, 136 males, 244 limbs with CLI) were(More)
AIMS No standardized local thrombolysis regimen exists for the treatment of pulmonary embolism (PE). We retrospectively investigated efficacy and safety of fixed low-dose ultrasound-assisted catheter-directed thrombolysis (USAT) for intermediate- and high-risk PE. METHODS AND RESULTS Fifty-two patients (65 ± 14 years) of whom 14 had high-risk PE (troponin(More)
PURPOSE To report an angiographic investigation of midterm atherosclerotic disease progression in below-the-knee (BTK) arteries of claudicants. METHODS Angiograms were performed in 58 consecutive claudicants (35 men; mean age 68.3+/-8.7 years) with endovascular treatment of femoropopliteal arteries in 58 limbs after a mean follow-up of 3.6+/-1.2 years.(More)
PURPOSE To assess the extent of early recoil in patients with critical limb ischemia (CLI) undergoing conventional tibial balloon angioplasty. METHODS Our hypothesis was that early recoil, defined as lumen compromise >10%, is frequent and accounts for considerable luminal narrowing after tibial angioplasty, promoting restenosis. To test this theory, 30(More)
