Arteriovenous Access Thrombosis. A fistula can thrombose either early or late after its creation. Early thrombosis of a fistula is most often due to an inflow problem (juxta-anastomosis stenosis or accessory vein) while late thrombosis tends to be due to an outflow stenosis.

2016年9月27日 · Early thrombosis of a fistula is most often due to an inflow problem (juxta-anastomosis stenosis or accessory vein) while late thrombosis tends to be due to an outflow stenosis. If either of these lesions is left untreated, this results in thrombosis of the fistula.

2019年6月28日 · (i) When left untreated, stenosis in a hemodialysis access can lead to the formation of a blood clot, also known as thrombosis. The risk of stenosis can be minimized by properly caring for your dialysis access and receiving quality dialysis access care.

The most important complications of fistulae for HD are lymphedema, infection, aneurysm, stenosis, congestive heart failure, steal syndrome, ischemic neuropathy and thrombosis. In HD patients, the most common cause of vascular access failure is neointimal hyperplasia.

2022年5月17日 · Leg blood clots may lead to a condition called deep vein thrombosis (DVT). deep vein thrombosis (DVT) can be life-threatening if the clot travels to the lungs (pulmonary embolism). Depending on where the fistula is, it may lead to a stroke.

Arteriovenous fistula (AVF) complications are classified based on fistula outcomes. This review aims to update colour Doppler (CD) and pulse wave Doppler (PWD) roles in managing early and late complications of the native and prosthetic AVF.

Fistula thrombosis should be treated as soon as possible or within 48 h. The duration and site of AV fistula thrombosis as well as the type of access are important determinants of treatment outcome. Timely declotting allows immediate use without the need for a central venous catheter.

2024年11月25日 · This topic provides an overview of general issues regarding arteriovenous (AV) fistula maintenance, including measures to prevent AV fistula thrombosis and management of the high-risk fistula. These same considerations with respect to AV grafts are reviewed separately.

Arteriovenous fistula thrombosis is a condition characterized by the formation of a blood clot within an arteriovenous fistula, which is an abnormal connection between an artery and a vein. This can lead to reduced blood flow, complications in dialysis treatment, and potential damage to the affected blood vessels.

2022年7月5日 · What is an arteriovenous fistula? An arteriovenous fistula is a medical condition where an artery and vein connect directly, causing blood to flow between them. It can happen at virtually any place in your body where an artery and vein are close together, especially inside of your organs and limbs (arms and legs).
