Disease relevance of Arteriovenous Fistula

• Thirty-eight of these patients had chronic obstructive airways disease; 13, primary pulmonary hypertension; seven, recurrent pulmonary embolism; four, the Eisenmenger syndrome; and one, multiple pulmonary arteriovenous fistula [1].
• Two were for residual atrial septal defects, one for an atrial septal defect and an intrapulmonary arteriovenous fistula, and one for a residual ventricular septal defect [2].
• We hypothesized that the TGF-beta1 genotype, by influencing the development of arteriovenous fistula stenosis, determines the risk for vascular access failure [3].
• Increased renin secretion in this instance supports the proposed mechanism of diastolic hypertension with renal arteriovenous fistula [4].
• Endothelin-secreting angiosarcoma occurring at the site of an arteriovenous fistula for haemodialysis in a renal transplant recipient [5].

High impact information on Arteriovenous Fistula

• Hyperparathyroidism vs arteriovenous fistula as cause of 'clubbing' [6].
• Necrosis of the hand after daunorubicin infusion distal to an arteriovenous fistula [7].
• Before deactivation of smooth muscle with EDTA, cross-sectional areas of the vessel wall and pulse pressures in sham pial arterioles were significantly greater (P < .05) in arteriovenous fistula rats than in control rats (cross-sectional area, 1468 +/- 100 versus 1129 +/- 104 microns 2; pulse pressure, 26 +/- 1 versus 14 +/- 1 mm Hg) [8].
• The role of hyperparathyroidism, erythropoietin therapy, and CMV infection in the failure of arteriovenous fistula in hemodialysis [9].
• PURPOSE: To evaluate polyethylene terephthalate and polyurethane as coatings of vascular endoprostheses in the treatment of experimental arteriovenous fistulas (AVFs) [10].

Chemical compound and disease context of Arteriovenous Fistula

• Coronary arteriovenous fistula as a cause for reversible thallium-201 perfusion defect [11].
• A combination of stainless steel coil and compressed Ivalon: a new technique for embolization of large arteries and arteriovenous fistulas [12].
• Grafts with a low peak systolic velocity less than 30 to 40 cm/s and high outflow resistance (absent diastolic flow) underwent procedures (distal arteriovenous fistula, sequential bypass grafting) to augment flow; if this was not possible, the grafts were treated with an antithrombotic regimen, including heparin, dextran, and antiplatelet therapy [13].
• A distal arteriovenous fistula and aspirin (300 mg) and dipyridamole (50 mg orally every day) starting 3 days before surgery were used to protect early patency of all grafts [14].
• All patients had transfemoral venous thrombectomy with construction of an inguinal arteriovenous fistula and perioperative anticoagulation with heparin with a switch to warfarin sodium for at least 12 postoperative months [15].

Biological context of Arteriovenous Fistula

• A case of arteriovenous fistula in the brain detected by the combined use of maternal serum alpha-fetoprotein (AFP) and ultrasound in the third trimester of pregnancy is described [16].
• In a time control series in dogs with arteriovenous fistula (n = 4), indomethacin vehicle did not alter ANF-induced natriuresis or renal hemodynamic function [17].
• METHODS: Using a cross-sectional design in this study, the relationship between arteriovenous fistula (AVF) obstruction and the MTHFR C677T point mutation was examined in 337 HD patients [18].
• The aim of this study was to investigate the possible influence of arteriovenous fistula (AVF) on nerve conduction velocity in patients on intermittent hemodialysis and its relevance to the pathogenesis of carpal tunnel syndrome (CTS) [19].

Anatomical context of Arteriovenous Fistula

• Blood flow was increased by construction of an arteriovenous fistula between the right iliac artery and vein in six cynomolgus monkeys fed a diet containing 2% cholesterol and 25% peanut oil [20].
• INTERVENTION: Cerebral angiography demonstrated a high-flow arteriovenous fistula between the junction of the petrous and laceral portions of the right internal carotid artery and right IPS, with rapid filling of both cavernous sinuses [21].
• The term 'aneurysm of the vein of Galen' encompasses a range of different midline arteriovenous fistula malformations [22].
• Angiography revealed a congenital arteriovenous fistula of the vertebral artery at C2 level being fed by a left ascending cervical artery [23].
• Brachial plexus block with ropivacaine and bupivacaine for the formation of arteriovenous fistula in patients with end-stage renal failure [24].

Gene context of Arteriovenous Fistula

• Iatrogenic arteriovenous fistulas between the aorta or its major branches and the vena cava or its tributaries resulting from lumbar disc operations are uncommon but serious problems for the vascular surgeon [25].
• Congenital arteriovenous fistula producing carpal tunnel syndrome [26].
• Hypertension and post-traumatic renal arteriovenous fistula: demonstration of unilaterally elevated renin secretion [4].
• Patients with a ventricular or an atrial septal defect or a probable pulmonary arteriovenous fistula were excluded [27].
• Preservation of the vasa vasorum does not maintain wall compliance and complete mobilization of the vein relieves any uneven tension and ensures that all venous tributaries are ligated, removing the risk of arteriovenous fistulas [28].

Analytical, diagnostic and therapeutic context of Arteriovenous Fistula

• Decreasing thrombogenicity by wetting the grafts with heparin and increasing the blood flow by constructing an arteriovenous fistula helps in overcoming failure of venous vascular prostheses [29].
• Experience with central high flow arteriovenous fistulas in patients requiring chronic parenteral chemotherapy or hemodialysis [30].
• Combined use of alpha-fetoprotein and ultrasound in the prenatal diagnosis of arteriovenous fistula in the brain [16].
• Use of a partially deployed wallstent to act as an inferior vena cava filtration device during coil embolization of a high-flow arteriovenous fistula [31].
• Home parenteral nutrition via arteriovenous fistula [32].
