PURPOSE To compare the clinical safety and efficiency of two optional inferior vena cava (IVC) filters. MATERIAL AND METHODS Ninety-three consecutive Günther Tulip filters (92 patients) were compared with 83 consecutive OptEase filters (80 patients). Filters were placed at the same institution in patients with high-risk multiple trauma or those undergoing(More)
PURPOSE To present a technique for renal and visceral revascularization allowing complete endovascular treatment of a ruptured type IV thoracoabdominal aneurysm using devices already stocked in most centers performing endovascular aneurysm repair. TECHNIQUE Open arterial access is obtained to both common femoral arteries and the left subclavian artery(More)
OBJECTIVES Prophylactic vena cava filters (VCF) are efficient in preventing pulmonary embolism. Filter retrieval avoids the potential long-term complications of permanent VCF. Clinical evaluation was focused on filter-related complications and feasibility of retrieval in high-risk trauma patients. METHODS Analysis of single-institution consecutive case(More)
We discuss the case of a young man presenting with "renal colic" whose flank pain however, turned out to be the result of renal infarction due to dissection of an accessory renal artery with fibromuscular dysplasia. The condition was diagnosed after exclusion of nephrolithiasis and work-up of new onset arterial hypertension developing in the later course.(More)
This study was designed to assess retrospectively short- and mid-term outcomes of the use of a suture-mediated closure device to close the antegrade access in patients undergoing percutaneous aspiration thrombectomy with large catheters for acute leg ischemia. Between November 2005 and February 2010, a suture-mediated active closure system (ProGlide® 6F,(More)
Lymphatic cysts can either represent lymphatic malformations (LMs) or may occur after trauma or operation. Independent of their etiology lymphatic cysts can cause functional impairment and recurrent skin infections. We report the successful use of OK-432 injected transcutanously to treat lymphatic macrocysts. Treatment of LMs with OK-432 has been reported(More)
PURPOSE Computed tomography (CT)-guided navigation during percutaneous radiofrequency (RF) ablations of liver and kidney lesions is hampered by respiratory motion and time-dependent lesion conspicuity after contrast agent injection. Therefore, target immobilization by general anesthesia with high-frequency jet ventilation (HFJV) instead of conventional(More)
The present report describes a transfemoral, single-access OptEase filter retrieval technique that takes advantage of its particular two-level mirrored umbrella design. By threading a stiff "buddy" guide wire through the device, the filter is aligned to the long vena cava axis. This technique separates the retrieval hooklet from the adjacent venous wall,(More)
The design of the Excluder, which is considered a 3rd generation device for endovascular repair of abdominal aortic aneurysms, is described. Based on a literature search, clinical short- to mid-term results are reviewed. So far, efficacy and safety of the Excluder for elective and emergent aneurysm repair have been demonstrated. In none of the studies(More)
