UNLABELLED INTRODUCTION Although pulmonary arteriovenous malformations are relatively rare disorders, they are an important part of the differential diagnosis of common pulmonary problems, such as hypoxemia, dyspnea on exertion and pulmonary nodules. CASE PRESENTATION An 11-year-old Croatian boy of Mediterranean origin with a history of asthma since childhood was admitted to our hospital f...

HKJGOM 2011; 11 (1) 67 Introduction Pulmonary arteriovenous malformations (PAVMs) are rare vascular disorders known to produce life-threatening complications, including haemoptysis, intrapleural haemorrhage, stroke, brain abscess, and hypoxaemia. Since its first description by Churton in 18971, more than 500 cases have been reported in the literature2. Pregnancy and PAVM are strongly linked wit...

Capillary malformation-arteriovenous malformation (CM-AVM) is a newly discovered hereditary disorder. Its defining features are atypical cutaneous multifocal capillary malformations often in association with high-flow lesions: cutaneous, subcutaneous, intramuscular, intraosseous and cerebral arteriovenous malformations and arteriovenous fistulas. Some patients have Parkes Weber syndrome - a lar...

Background and Purpose Surgical excision of cerebral arteriovenous malformations (AVMs) may be complicated by postoperative breakthrough edema and hemorrhage and by intracranial hypertension. Embolization, staged resection, and meticulous surgical technique have decreased but not completely eliminated this complication. In this study we prospectively assess the prevalence of intracranial hypert...

AIMS We discuss our experience with the surgical management of scalp vascular malformation and review the literature on the subject. SETTINGS AND DESIGN A prospective case-control study of eight patients with scalp vascular malformations admitted to our hospital between 1997 and 2002. METHODS AND MATERIALS All the patients were investigated with selective internal and external carotid angio...

Hereditary haemorrhagic teleangiectasia (HHT) or Rendu-Osler-Weber disease is a genetic autosomal-dominant disorder characterised by the presence of vascular telangiectases in mucocutaneous tissues, visceral organs and the Central Nervous System. Pulmonary arteriovenous malformations have a variable incidence rate ranging between 15-33%, and the safest treatment is transcatheter embolotherapy. ...

PURPOSE To present the treatment outcome after embolization of arteriovenous malformations. METHODS All patients with cerebral arteriovenous malformations treated in 1987 and 1988 (27 patients, group I) and in 1992 and 1993 (35 patients, group II) were compared regarding treatment results and clinical outcome. RESULTS Complications of the treatment occurred in 52% of group I and 22% of grou...

Spinal arteriovenous malformations originate probably by a detention in the normal evolution of the embryonic vessels. By unknow reasons, and about the end of the first month of the embryonic life, the normal differentation toward arteries, veins and capillaries fails, and non-differentiated vesseIs persist in the adult life, mantaining the anatomic and physiologic characteristics of the embryo...

ARTERIOVENOUS MALFORMATIONS AVM Incidence Since only 12% of AVMs cause symptoms, the incidence of AVM in the United States is not fully known. The incidence is thought to be around 1 per 100,000, equaling 300,000 cases. As technology advances and early detection increases, these numbers may rise. The average age of AVM diagnosis is 33 years, with 64% being identified before age 40 (Greenburg, 2...
