Background & Aims: This study was done in hem dialysis patients who referred to Imam Khomeini hospital of Urmia for insertion of arterial -venous fistula with Gore-tex, in whom there was not possibility of natural fistula. Objectives were assessment and comparison of complications and patency of arterial-venous fistulas was done with 6 and 8 mm Gore-tex graft in the upper limb and comparison of...
Background: Brucellosis is a zoonotic disease that is common in developing countries such as Iran which is a serious medical impact. Vascular complications, including arterial and venous associated with Brucella infection, have rarely been reported. In a review of articles, it is clear that , only five cases of deep venous thrombosis (DVT) of the lower extremities and just one case of cerebra...
Introduction: Recent studies show that exposure to heavy metals can affect thyroid function. This study aimed to assess heavy metals in breast milk during the first few days postpartum and their relationships with hyperthyrotropinemia in neonates. Materials and Methods: In this case-control study, 82 mother-infant pairs, consisting of 21 pairs (neonates with hyperthyrotropinemia) in the case gr...
OBJECTIVE Venous function contributes to the pathogenesis of thrombophlebitis, venous thrombosis, and possibly to arterial hypertension. Venous disease is presumably heritable; however, the genetic variance of venous function is unknown. METHODS AND RESULTS We determined the heritability of venous function in 46 twin pairs (24 monozygotic, age 35+/-11 years, 14 men, 34 women; 22 dizygotic, ag...
The relationship of arterial blood flow and venous volume to venous flow velocity was studied in normal subjects. The effects of current modes of treatment in venous thrombosis and of a vasodilator drug on venous flow velocity were also investigated. Total calf flow and venous volume were measured by venous occlusion plethysmography while venous flow axial velocity was determined by the transit...
Venous leg ulcers are extremely common in the United States. They affect between 500,000 and 2 million people annually, and are responsible for over 50 percent of all lower extremity ulcers.1 Elevated venous pressure, turbulent flow, and inadequate venous return are the common causes of venous leg ulcers. Risk factors for chronic venous disease include underlying conditions associated with poor...
OBJECTIVES The vast majority of ICU patients require some form of venous access. There are no evidenced-based guidelines concerning the use of either central or peripheral venous catheters, despite very different complications. It remains unknown which to insert in ICU patients. We investigated the rate of catheter-related insertion or maintenance complications in two strategies: one favoring t...
The present study aims to investigate and compare the diagnostic and prognostic value of cavernosography with 320-row dynamic volume computed tomography (DVCT) versus conventional cavernosography in men with erectile dysfunction (ED) caused by venous leakage. A total of 174 patients diagnosed with ED were enrolled and received cavernosography with 320-row DVCT (DVCT group) and conventional cave...
Anomalous Pulmonary venous connection is drainage of one or more pulmonary veins outside left atrium. Venous Connection most common on Left side upper vein drains directly into innominate to ultimately drain right Right Partial can be Superior Vena Cava, Atrium, Innominate rarely Inferior Cava.
