Active clinical trials for "Vascular Diseases"

A controlled, randomized, open-label, multicenter study evaluating if early initiation of everolimus and early elimination of cyclosporine in de novo heart transplant recipients can improve long-term renal function and slow down the progression of chronic allograft vasculopathy

The Zilver PTX Registry Study is a prospective, non-randomized, open-label, multicenter single-arm study enrolling patients in Europe, Asia, and North America with de novo or restenotic (including in-stent restenosis) lesions of the above-the-knee femoropopliteal artery (SFA). The primary endpoint of the study is event-free survival (EFS) at 6 months.

The investigators evaluated whether primary implantation of a self-expanding nitinol stent yielded anatomical and clinical benefits superior to those afforded by percutaneous transluminal angioplasty with optional secondary stenting.

To demonstrate equivalence in patency performance of GORE-TEX PROPATEN Vascular Grafts and Thin Walled GORE-TEX Stretch Vascular Grafts in a peripheral bypass application to support a claim of substantial equivalence.

BALI (Bone marrow Autograft in Limb Ischemia) is a randomized double-blind trial comparing implantation of bone marrow - mononuclear cells versus placebo in patients presenting with critical leg ischemia and no surgical option. The main end point is the survival without major amputation 6 months after implantation. Biological studies are performed on bone marrow mononuclear cells (BM-MNC) to evaluate their angiogenic properties.

The STARR network registry consists of a 4 spoke 1 hub system. Which will consist of prospective collection, recording, and regular analysis of telestroke patient consultation and care data for the purpose of quality measure assessment and improvement and benchmarking against other national and international telestroke programs.

This study evaluates the ability of the drug sildenafil to improved exercise capacity, cardiac performance during exercise, and quality of life in patients with moderate to severe CF lung disease. 3/4 of the subjects will receive sildenafil and 1/4 will receive placebo.

The objective of this study is to evaluate the performance of the Zilver PTX stent thumbwheel delivery system.

Comparison of recurrent-restenosis rates 6 months after angioplasty of in-stent restenoses or in-stent reocclusions in the superficial femoral artery (SFA) using either a standard balloon (Admiral Xtreme, Invatec) or a paclitaxel-eluting balloon (In.Pact™ Admiral, Invatec).

Aimed to compare the success in the peripheral intravenous puncture (PIP), progression and placement of PICC in children, according to the use of Doppler vascular ultrasound (DVUS) or traditional method; to identify the influence of the DUVS in the time expended to PICC placement. Methods: Clinical, randomized and controlled trial conducted after ethical merits of research endorsement and the obtaining of consent for those responsible for the children. The sample, calculated in 42 PICC to obtain a power of 0,85, was distributed randomly into two groups, experimental group (EG) and controlled group (CG). To the statistical analyzes Pearson Chi-square, Fisher's Exact Tests, Generalization of Fischer's Exact and Mann-Whitney tests was applied (5%). Of the 42 catheters, 21 (50.0%) were implemented in EG and 21 (50.0%) in CG. The PIP was obtained in the first attempt in 90.5% of the punctures of the EG and in 47.6% of the GC, (p=0.003). PICC were implanted successfully in 18 (85.7%) children of GE and 11 (61.1%) of CG (p = 0.019). The median of the time spent to the procedure was significantly higher (p=0.001) in CG (50 minutes) when compared to EG (median 20 minutes).
