INTRODUCTION Arteriovenous fistula of the superior mesenteric blood vessels is a rare complicaton in abdominal surgery. CASE REPORT We presented a 49-year-old man with cramp-like abdominal pain, abdominal distension and weight loss symptoms, with a history of previous small bowel resection and right colectomy, due to Crohn disease, 16 years ago. Clinical examination revealed a paraumbilical p...

PURPOSE To determine the potential and limitations of MR angiography in the evaluation of spinal vascular malformations. METHODS Eleven consecutive patients with spinal vascular malformations proved with spinal selective arteriography underwent two-dimensional phase-contrast MR angiography. RESULTS Abnormal vessels within the spinal canal were identified with MR angiography in 10 patients. ...

PURPOSE To evaluate the feasibility and safety of Guglielmi detachable coils for endovascular treatment of extracranial aneurysm and arteriovenous fistula. MATERIALS AND METHODS Embolization with Guglielmi detachable coils delivered through Tracker-18 microcatheters was performed in 16 patients. This patient group had eight renal artery aneurysms and 11 arteriovenous fistulas (three cases of ...

The number of end stage of renal disease patients that need dialysis or renal transplantation increased in the world. Insertion and maintenance functional vascular access remain the challenging problem. Arteriovenous fistula is the common access for dialysis but complication and its failure is the main problem. The aim of this study is to evaluate patients with arteriovenous fistula during 4 ye...

Twenty-three out of thirty-six patients using a forearm arteriovenous fistula for dialysis reported symptoms of carpal tunnel syndrome in the fistula hand during dialysis. By contrast with other reported groups of patients with the syndrome, symptoms were common in male patients, and confined to the non-dominant (fistula) hand. Predialysis venous pressure in the hand and hand volume were increa...

Communication between the coronary arteries and the cardiac chambers is a rare event. In the 22,500 post-mortems performed at the General Hospital, Singapore, over the past decade, there were some 520 cases of congenital heart disease. In this material there were three examples of this unusual anomaly, all occurring in infants of Chinese race. As about 30 cases of this anomaly have now been des...

The combination of coronary arteriovenous fistula to the coronary sinus (CS), dilatation of the entire length of coronary artery, coronary aneurysm and persistent left superior vena cava (PLSVC) is very rare. We present the case of a 63-year-old female admitted for dyspnea on exertion, orthopnea, and facial edema. Echocardiography detected a giant coronary artery with shunt flow, dilated CS and...

BACKGROUND Arteriovenous fistulas are critical for haemodialysis, but maturation rates remain poor. Experimental and anecdotal evidence has supported the use of transdermal glyceryl trinitrate (GTN) patches. The aim of this RCT was to determine whether use of a GTN patch aids arteriovenous fistula maturation. METHODS Patients referred for arteriovenous fistula formation were eligible. The GTN...

Coronary arteriovenous fistulas are among rare anomalies of coronary arteries. Role of X-ray angiography is well established in identification and characterization of these anomalies, however there accurate course and termination is often not defined. We demonstrate role of routine cardiovascular MRI in non-invasively diagnosing and characterizing the course and termination of these anomalous c...
