brain abscess/hypoxia

A case of pulmonary arteriovenous malformation and brain abscess is presented. The case report emphasizes the importance of pulmonary arteriovenous malformation which is often seen in hereditary haemorrhagic telangiectasia as predisposing factor for brain abscess formation.

Cerebral abscess is a recognized complication of pulmonary arteriovenous malformations (PAVMs) that allow systemic venous blood to bypass the pulmonary capillary bed through anatomic right-to-left shunts. Broader implications and mechanisms remain poorly explored. Between June 2005 and December

BACKGROUND Causes of brain abscesses are multiple and often unclear. We present the case of a pregnant woman who developed a temporal brain abscess revealed by an epileptic seizure. METHODS Perfusion lung scan was performed because she had a mild hypoxemia: absence of contrast into the pulmonary

Large pulmonary arteriovenous malformations (PAVMs) constitute an uncommon cause of central cyanosis with septic embolism and brain abscess. This large right to left shunt can lead to chronic severe hypoxemia and significant morbidity and mortality if untreated. Conservative parenchyma-sparing lung

Cerebral abscess is a serious neurological condition that is often of unclear etiology. Management is usually medical therapy with or without direct drainage, and when patients have recurrent episodes a structural abnormality should be considered. Persistent left superior vena cava is an uncommon

A case of pulmonary arteriovenous fistula (PAVF) complicated by brain abscess is presented. The incidence of this complication has been quoted to be 1-5%. After reviewing all inpatients in Chang Gung Memorial Hospital from 1977 to 1988, we found a total of 9 cases of PAVF; only one case of PAVF

A 27-day-old boy had convulsion associated with brain abscesses and severe hypoxemia at the age of 3 months. Congenital absence of the portal vein (CAPV) and some associated anomalies were detected by radiological examinations. Brain abscess and hypoxemia were thought to be serious complications

Background: A rare case of cerebral abscess concurrent with pulmonary arteriovenous fistula (PAVF), hyperhemoglobinemia, and hypoxemia was reported. Case presentation: A

We report a rare case of recurrent brain abscess associated with congenital pulmonary arteriovenous fistula. A 52-year-old man was admitted to our hospital in October, 1999 because of a sudden stroke-like onset of right hemiparesis, right hemiparesthesia, dysarthria and sensory aphasia. He had a

Hereditary hemorrhagic telangiectasia is a rare autosomal-dominant condition affecting visceral blood vessel development. Cerebral and most commonly pulmonary arteriovenous malformations are found in the majority of symptomatic patients. The most common complications include embolic strokes and

BACKGROUND Brain abscesses occur in 5 to 13 % of patients with pulmonary arteriovenous malformation (PAVM), more often present in Rendu-Osler-Weber disease or hereditary hemorrhagic telangiectasia (HHT). METHODS A 51-year-old man with a history of transient Parinaud syndrome at 37 years complained

Hemorrhage into the abscess cavity is a complication of brain abscess. It has been reported to be due to inflammation which results in the damage of the fragile neovasculature of the abscess wall. Hypoxia caused by Fallot's tetralogy or other congenital heart diseases facilitates the damage of these

Cerebral abscess is a classical complication of cyanotic congenital heart disease. The authors report 7 cases of cerebral abscess diagnosed since 1982. One asymptomatic patient died of a postoperative cerebral haemorrage. The child was repatriated from Africa for complete correction of his cardiac

As a result of hypoxia following right-to-left shunts, cerebral bacterial spreading and an altered blood-brain-barrier permeability, brain abscesses (BA) are typical complications in patients with cyanotic congenital heart disease. In 483 prospectively followed patients the incidence of BA was

A forty-year-old woman who developed brain abscess was found to Rendu-Osler-weber syndrome with multiple arteriovenous fistulas of the left lung. Therapeutic embolization of pulmonary arteriovenous fistulas was performed for the prevention against brain abscess and improvement of hypoxia.
