This study evaluates the role of an implanted ultrasonic fiducial marker and automated Duplex for evaluating the maturation of peripheral arteriovenous fistulae created for the purpose of establishing long term hemodialysis access in patients with end stage renal disease.

40000 patients are hemodialysis each year in France . In the case of chronic care, 78% of patients have an arteriovenous fistula. In order to perform the hemodialysis session, 2 technique...
A well-functioning vascular access is essential for effective hemodialysis. The native arteriovenous fistula (AVF) is the preferred vascular access because of the lower thrombosis and infe...
Isometric exercise has been shown to increase the diameter and the blood flow rate of forearm veins.At present, more studies focus on the perioperative period to promote the maturation of ...
The purpose of this study is assessment of safety, efficacy, and short-term outcome of SQUID™ in the embolization of Dural Arteriovenous Fistula
Arteriovenous fistula (AVF) is now the optimal method of obtaining vascular access for dialysis. Measures such as systemic anticoagulation have been proposed as means of increasing patency...
Intraorbital arteriovenous fistula is a rare vascular disease characterized by an acquired arteriovenous communication without direct cavernous sinus involvement. Intraorbital arteriovenous fistula ma...
Initial hemodialysis access with arteriovenous fistula (AVF) is associated with superior clinical outcomes compared with arteriovenous graft (AVG) and should be the procedure of choice whenever possib...
Intracranial dural arteriovenous fistulas (DAVFs) are an uncommon pathology, and a sphenoparietal drainage pattern is certainly rare. We present a case of a de novo sphenoparietal dural arteriovenous ...
Renal arteriovenous fistula with renal artery aneurysms and dilated renal veins presents as an infrequent lesion. Endovascular therapy has recently been considered the first-line treatment for these c...
This video demonstrates the diagnosis and surgical ligation of a C1 dural arteriovenous fistula via a far lateral, transcondylar approach. The patient's dural arteriovenous fistula was identified by M...
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
A vessel that directly interconnects an artery and a vein, and that acts as a shunt to bypass the capillary bed. Not to be confused with surgical anastomosis, nor with arteriovenous fistula.
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).
An abnormal anatomical passage that connects the VAGINA to other organs, such as the bladder (VESICOVAGINAL FISTULA) or the rectum (RECTOVAGINAL FISTULA).
