Objective The aim of this study was to describe the demographic, clinical and anatomic characteristics of coronary arteriovenous fistulas in adult patients who underwent open cardiac surgery and to review surgical management and outcomes. Methods Twenty-one adult patients (12 female, 9 male; mean age: 56.1±7.9 years) who underwent surgical treatment for coronary arteriovenous fistulas were re...

BACKGROUND AND PURPOSE The diagnosis of spinal vascular malformations may be challenging on conventional MR imaging because neither the location of the signal abnormality in the spinal cord nor the level of the abnormal flow voids correlates with the level of the fistula. We conducted a retrospective evaluation of the utility of using a time-resolved imaging of contrast kinetics sequence in the...

Percutaneous arterial catheterisation is commonly undertaken for a range of diagnostic and interventional procedures. Iatrogenic femoral arteriovenous fistulas are an uncommon complication of these procedures. Most are asymptomatic and close spontaneously, but can rarely increase in size leading to the development of symptoms. We report a case of an iatrogenic femoral arteriovenous fistula, cau...

OBJECTIVE To review the experience with Onyx embolisation of cerebral arteriovenous malformation. DESIGN Prospective study. SETTING A regional neurosurgical centre in Hong Kong. PATIENTS Data of patients with cerebral arteriovenous malformation who underwent Onyx embolisation over a 14-month period were prospectively collected. RESULTS Eleven sessions of Onyx embolisation were performed...

During the last 25 years, 20 patients with cirrhosis of liver with severe cyanosis and gross clubbing simulating congenital cyanotic heart disease were subjected to cardiac catheterization and angiography, splenography, liver function tests, and liver biopsy. No portopulmonary fistulas could be demonstrated. The cyanosis and clubbing were secondary to right to left intrapulmonary shunting acros...

Arteriovenous fistula presents rarely with ascites. Diagnosis, with an elusive clinical presentation, is often incidental or delayed. A 35-year-old woman presented with ascites and cardiac decompensation. Contrast enhanced computed tomography revealed arteriovenous fistula between the left common iliac artery aneurysm and the left common iliac vein. The patient underwent endovascular treatment ...

BACKGROUND Uterine arteriovenous malformation is a rare but potential life-threatening source of bleeding. A high index of suspicion and accurate diagnosis of the condition in a timely manor are essential because instrumentation that is often used for other sources of uterine bleeding can be lead to massive hemorrhage. CASE We describe here a case of uterine arteriovenous malformation. A 32-y...

During the last 26 years, 21 patients with cirrhosis of the liver with severe cyanosis and gross clubbing simulating congenital cyanotic heart disease were subjected to cardiac catheterisation and angiography, splenography, liver function tests and liver biopsy. One patient had tetralogy of Fallot in addition, which was satisfactorily corrected. He continued to be intensely cyanosed and dyspnoe...

Arteriovenous aneurysms may be congenital (arteriovenous malformation, AVM) or acquired (arteriovenous fistula, AVF). AVFs after a renal transplant biopsy are seldom, but well recognized, usually harmless complications [1]. Congenital AVMs are usually of the cirsoid (racemose) type [2], characterized by a tangle of tortuous vessels of small diameter, with multiple varix-like communications betw...

BACKGROUND Arteriovenous malformations (AVM) of the urinary tract are extremely rare. To the best of our knowledge, only three case of AVM of the ureter have been described in the literature so far. CASE PRESENTATION We present an additional, fourth case of an AVM of the ureter, clinically presented as asymptomatic haematuria and an obstructive process in the left ureter. Ureteroscopic evalua...
