Epistaxis can be life threatening and may not respond to conventional conservative measures such as packing. In our institution, between 1984 and 1991, we have treated 65 patients with embolization who had epistaxis that did not stop with nasal packing, with a success rate of 90%. This case report illustrates an unusual example of epistaxis due to a right frontal arteriovenous malformation (A V...

OBJECTIVE To analyze our experience with a second radiosurgical treatment for brain arteriovenous malformations (BAVMs) after an unsuccessful first radiosurgical treatment. METHODS Between 1993 and 2000, 242 patients were treated by the Toronto Sunnybrook Regional Cancer Center using a LINAC system. Fifteen of these patients required a second radiosurgical intervention due to the failure of t...

OBJECTIVE To evaluate results achieved with radiosurgery and complications of the procedure when treating arteriovenous malformations with linear accelerator. METHODS This retrospective study was conducted between October 1993 and December 1996. Sixty-one patients with arteriovenous malformations were treated with radiosurgery utilizing a 6MV energy linear accelerator. Ages of the 32 female a...

Multiple pulmonary arteriovenous malformations (PAVM) constitute an uncommon cause of respiratory disability. They may lead to severe hypoxaemia via right-to-left shunts and are sources of substantial mortality and morbidity. Conservative surgical resection has been proposed as the treatment of choice. More recently, percutaneous balloon or coil embolization of the feeding vessels offered an ef...

Arteriovenous malformations of the lung are rare pulmonary vascular disorders which can suddenly lead to life threatening complications. Haemothorax due to rupture of a pulmonary arteriovenous malformation (PAVM) is very rare. We report here a case of a 39 year-old lady who presented with an acute onset of shortness of breath due to right-sided massive haemothorax and was subsequently detected ...

BACKGROUND Paradoxical embolism due to pulmonary arteriovenous malformations is the main mechanism of brain infarction in patients with hereditary hemorrhagic telangiectasia. International Guidelines have recently been published to clarify the performance of screening tests and the effectiveness of treatment for pulmonary arteriovenous malformations. CASE PRESENTATION We present two cases of ...

Arteriovenous malformations have only rarely been implicated as a cause of basal ganglia dysfunction. In four instances where such a lesion was uncovered, abnormal involuntary movements were present. In two, tremor involving the contralateral limbs occurred, while in others the head and neck were involved in dystonic movements and posture. The clinical and angiographic characteristics of these ...

Klippel-Trenaunay-Weber syndrome (KTWS) is a congenital disorder characterized by cutaneous capillary malformations, venous-lymphatic anomalies, hypertrophy of soft tissue and bone in the area of increased vascularity and arteriovenous fistulas with shunting. In this article we report the case of a 25 year old man with KTWS who had multiple surgical operations because of arteriovenous malformat...

Introduction Treatment of recurrent severe gastrointestinal bleeding due to arteriovenous malformations may require complex resections. In some particular locations, extensive surgery is the only way out, as shown in this report. Case Report A 2.5-year-old child suffered repeated episodes of upper gastrointestinal bleeding since the first month of life. After an extensive diagnostic workout, th...
