Implanted venous access device (IVAD) late dysfunction is commonly caused by fibrin sheath formation. The standard method of endovascular fibrin sheath removal is performed via the femoral vein. However, it is not always technically feasible and sometimes contraindicated. Moreover, approximately 4-6 h of bed rest is necessary after the procedure. In this article, we describe an alternative meth...

BACKGROUND The femoral vein is an important site for central venous access in newborns and infants. The objectives of this study are to determine whether age or weight can be used clinically to predict the size of the femoral vein in newborns and infants, and to compare the size of the vein in each individual in both the supine and reverse Trendelenburg positions. RESULTS Analysis was done in...

The basic form of renal replacement therapy is haemodialysis. The duration and efficacy of this treatment depends on well-functioning vascular access. Short-term or long-term catheters are used if the arterial-venous fistula placement is not possible or not indicated. According to the recommendations of the NKF DOQI (National Kidney Foundation Disease Outcomes Quality Initiative), the first cho...

Introduction The standard approach to contemporary atrial fibrillation ablation involves obtaining trans-septal access to the left atrium from an inferior approach using percutaneous femoral venous access. Rarely, access to the heart from the inferior approach is not possible due to vascular anomalies or venous occlusions. In these unusual cases, a superior approach to pulmonary vein isolation ...

Transcatheter device closure was performed under general anesthesia in all the patients. The interventional treatment modality was approved by the ethics committee of our hospital, and informed consent was obtained before the procedure. Femoral artery and vein was routinely punctured. Left ventricular angiography was performed at 60° left anterior oblique and 20° cranial tilt position. The entr...

BACKGROUND Recurrent deep vein thrombosis (DVT) risk factors include a first idiopathic DVT, strongly suggesting the existence of undiagnosed and/or unidentified prothrombotic abnormalities. OBJECTIVES To evaluate the impact of locally increased red blood cell (RBC) aggregation on DVT pathogenesis in a rabbit model. METHODS DVT presence, flow and aggregation were measured in situ with ultra...

Effect of YM-12617, a selective and potent alpha 1-adrenoceptor antagonist on dose-response curves of alpha 1-adrenoceptor agonists, norepinephrine, phenylephrine and naphazoline, was tested in isolated rabbit vascular smooth muscles such as the femoral vein, portal vein and aorta. YM-12617 shifted the dose-response curves for norepinephrine and phenylephrine to the right and also declined the ...

Catheter insertion for intravenous hyperalimentation is a commonly and widely used clinical technique. When compared with the incidence of complications associated with insertions into the internal jugular vein or the subclavian vein, complications associated with insertions into the femoral vein are less frequent. In this paper, we describe a very rare complication of femoral vein catheter ins...

OBJECTIVE We report our initial experience with our newly developed percutaneous right-ventricular assist device (VAD) with CentriMag (perc CM-RVAD). METHODS A flexible outflow cannula placed from the right internal jugular vein to the pulmonary artery and an inflow cannula placed from the femoral vein to the right atrium constituted the perc CM-RVAD. When needed, biventricular support was pr...

Case presentation: A 39-year-old male smoker with a 2-year history of calf discomfort on ambulation culminating in left femoral-to-peroneal artery bypass presented with right leg discomfort and recurrent painful subcutaneous nodules on his feet and calves. Biopsy of a nodule from his right foot was interpreted as vasculitis with thrombosis and fibrinoid necrosis in subcutaneous vessels, and the...
