Ultrasound guidance for vascular cannulation has been proposed to increase success rates for vascular access and decrease complications.1,2 Ultrasound is also a tool for choosing the optimal target vessel: identifying size, position, and patency is especially important under certain conditions (peripheral vascular disease, obesity, hypotension). However, studies vary by methodology, patient pop...

SUMMARY Measurement of systemic vascular resistance in man currently requires arterial and venous cannulation, so that cardiac output and mean arterial blood pressure may be simultaneously determined. This report describes a noninvasive technic for determining systemic vascular resistance (SVR.), utilizing an ultrasonic method for cardiac output measurement, and a combination of sphygmomanometr...

PURPOSE To evaluate our results of stent-graft implantation for the endovascular treatment of peripheral vascular lesions. MATERIALS AND METHODS Seventeen patients underwent repair of iatrogenic, traumatic, or spontaneous vascular lesions by means of endovascular stent-grafts. The study cases consisted of 10 cardiac catheterization-induced femoral arteriovenous fistulas (AVFs) located between...

To determine whether hypertensive disorders of pregnancy (HDP) are associated with cardiovascular (CV) morbidity and mortality within 10-20 years following delivery. Retrospective cohort study including all women who delivered ≥1 at ≥20 weeks’ gestation a single health system from 1996-2008. Women were excluded if they had CV risk factors prior to their first delivery or no follow-up the after ...

In the basal state, approx. 60-70% of the insulin released from the pancreas is extracted by the liver; the remaining 30-40% is extracted by extrasplanchnic organs. Carbohydrate ingestion is known to stimulate pancreatic insulin release and to inhibit whole-body insulin extraction. The present study was undertaken to obtain a quantitative assessment of the degree to which early postprandial ins...

background central venous catheterization is done frequently in cardiac surgery and intensive care settings. faulty positioning of the catheter can cause many complications. objectives the aim of our study was to study the average depth of insertion and formulate a general guideline through the right internal jugular vein (ijv). patients and methods the right ijv was cannulated over a period of...

background: fenestration in the modified fontan operation allows right-to-left shunting, which reduces the fontan pathway pressure and improves cardiac output. however, on account of the fact that persistent right-to-left shunting results in cyanosis and paradoxical emboli, fenestration closure is recommended after recovery from the fontan operation. methods: this study recruited 3 patients who...
