Filter by: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).
The objective of this study is to evaluate the safety and effectiveness of the clinical and technical performance of the CorPath® 200 System in the delivery and manipulation of coronary guidewires and stent/balloon systems for use in percutaneous coronary interventions (PCI).
To determine whether complement factor H (CFH) and age-related maculopathy susceptibility 2 (ARMS2) genotypes have a pharmacogenetic effect on the treatment of polypoidal choroidal vasculopathy (PCV) with ranibizumab.
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 purpose of this study is to confirm the safety and performance of the 25 cm GORE® VIABAHN® Endoprosthesis with PROPATEN Bioactive Surface when used in the Superficial Femoral Artery.
This is a prospective, observational, single-arm, open-label, multicenter, postapproval registry study in China. The purpose of this study is to: - Evaluate the continued safety and effectiveness of the XIENCE V EECSS in a cohort of real-world patients receiving the XIENCE V EECSS during commercial use - Evaluate patient compliance to dual antiplatelet therapy (DAPT)
The purpose of this research study is to determine the frequency and severity of iron overload in patients with Sickle Cell Anemia and its relationship to blood vessel function. The investigators hypothesize that intermittent transfusions that these patients receive during hospitalizations produces significant iron overload and impairs blood vessel relaxation.
Currently, dorsal hand rejuvenation is an upcoming issue as patients seek plastic surgeons to address this highly visible area, although no specific statistics concerning the number of patients undergoing dorsal hand rejuvenation have been published yet. The solitary use of fillers, fat, sclerotherapy, skin excision, resurfacing and combinations of the above mentioned therapies have been reported in the literature, but still there is a lack of scientific literature about functional microcirculation of the dorsum of the hand. Furthermore, there is a lack of scientific data about functional microcirculation of the plantar foot in healthy subjects compared to patients suffering from Diabetes mellitus or peripheral arterial occlusive disease. Consequently, the aim of this study is the evaluation of the functional microcirculation of hands and feet in healthy subjects as well as patients suffering from the above mentioned diseases.
An abdominal aortic aneurysm (AAA) is a weakened and enlarged area in the abdominal aorta, which is a large blood vessel in the abdomen. Large AAAs (>55 mm diameter) carry a high risk of rupture, a surgical emergency that often leads to death due to severe internal bleeding. It has been suggested that regular exercise training might limit the rate at which AAAs develop. However, little is known about the safety and effectiveness of exercise training in these patients. This pilot study will examine the feasibility of supervised aerobic exercise training for patients with small AAAs (30 to 49 mm diameter). The investigators hypothesize that exercise training will be safe and useful for patients with small AAAs.
