Pulmonary Arteriovenous Malformations and Coronary Artery Fistulas
P ulmonary arteriovenous malformations (PAVMs) and coronary artery fistulas (CAFs) are infrequent clinical problems but can potentially cause significant morbidity and mortality. They are usually congenital, but acquired forms do occur. Treatment of these vascular abnormalities has evolved considerably during the last 2 decades. Percutaneous transcatheter closure of PAVMs and CAFs is now consid...
متن کاملEffects of Pentoxifylline on Oxygenation and Exercise Tolerance in Patients with Severe Chronic Obstructive Pulmonary Disease
Background: It was hypothesized that the use of Pentoxifylline would increase arterial O2 saturation and increase exercise tolerance in patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: We tested this hypothesis in 23 patients with COPD and pulmonary hypertension. Patients were randomized to receive Pentoxifylline or placebo, each for a 12-week period, in a prospectiv...
متن کاملEmbolisation of pulmonary arteriovenous malformations: no consistent effect on pulmonary artery pressure.
Increasing evidence supports the use of embolisation to treat pulmonary arteriovenous malformations (AVMs). Most pulmonary AVM patients have hereditary haemorrhagic telangiectasia (HHT), a condition that may be associated with pulmonary hypertension. The current authors tested whether pulmonary AVM embolisation increases pulmonary artery pressure (P(pa)) in patients without baseline severe pulm...
متن کاملPulmonary Arteriovenous Malformations
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...
متن کاملManagement of pulmonary arteriovenous malformations in pulmonary hypertensive patients: a pressure to embolise?
P ulmonary arteriovenous malformations (PAVMs) carry significant risks [1, 2]. Pulmonary arterial blood passing through these right-to-left shunts cannot be oxygenated, leading to hypoxaemia, with arterial oxygen tension and arterial oxygen saturation (Sa,O2) inversely related to the size of the shunt fraction. The fragile wall of the PAVM sac may rupture, leading to haemoptysis or haemothorax ...
