Objective: To report the surgical results obtained with the surgical correction of fistulae of coronary arteries in the pulmonary artery branch. Method: From 1995 to 1999, three female patients with diagnoses of isolated fistulae of coronary arteries confirmed by cinecoronariography underwent surgery. Results: No other associated heart diseases were observed in the patients. The main symptom of...

Pseudoaneurysms (PsA) and arteriovenous fistulae (AVF) of the thyrocervical trunk and its branches are rare complications of traumatic or iatrogenic arterial injuries. Most such injuries are iatrogenic and are associated with central venous catheterization. Historically, thyrocervical trunk PsA and AVF have been managed with open surgical repair; however, multiple treatment modalities are now a...

Interventional neuroradiology continues to play an increasing role in the treatment of intracranial aneurysms, the treatment of vasospasm related to subarachnoid hemorrhage, and the treatment of vascular malformations and fistulae of the brain and spine. New techniques for aneurysm embolization are examined, such as detachable coil systems, as are reports of intracranial angioplasty and superse...

BACKGROUND In hemodialysis, extracorporeal blood flow (Qb) recommendation is 300-500 mL/min. To achieve the best Qb, we based our prescription on dynamic arterial line pressure (DALP). METHODS This prospective study included 72 patients with catheter Group 1 (G1), 1877 treatments and 35 arterio-venous (AV) fistulae Group 2 (G2), 1868 treatments. The dialysis staff was trained to prescribe Qb ...

An increasing number of renal dialysis-dependent patients with Arterio-Venous fistulae are undergoing cardiac surgery.The fistula has important effects on systemic hemodynamics in dialysis patients. The flow is significantly and positively related to cardiac output and cardiac index, and inversely related to pulmonary vascular resistance.Few problems are encountered on cardiopulmonary bypass de...

−− Long-term vascular accesses are usually performed in patients submitted to renal replacement therapy using autologous vessels. When arterio-venous fistula creation is impossible, animal conduits have been used in order to obtain high patency rates. Bovine vessel heterograft has been introduced as a substitute for the construction of arterio-venous fistulas. However, when experimental researc...

BACKGROUND Haemodialysis vascular access dysfunction is currently a huge clinical problem. Although arteriovenous (AV) fistulae are the preferred mode of dialysis access, they have significant problems with both early (failure to mature) and late fistula failure. Both are characterized radiologically as a stenosis of the venous segment. Despite the magnitude of the clinical problem, the exact p...
