Hereditary telangiectasia and multiple pulmonary arteriovenous fistulas. Clinical deterioration during pregnancy.
نویسندگان
چکیده
We describe the effect of pregnancy on a woman with multiple pulmonary arteriovenous fistula. Pregnancy was terminated at 35 weeks' gestation because of severe hypoxemia. During the early postpartum period, the intrapulmonary shunt fraction enlarged, and hypoxemia worsened, necessitating emergency resection of the A-V fistula. Pregnancy may increase the intrapulmonary shunt fraction in patients with multiple pulmonary arteriovenous fistula through its effect on plasma volume and produce life-threatening hypoxemia near term or in the early postpartum period.

Pulmonary arteriovenous malformations (PAVM) expand during pregnancy because of increases in blood volume, cardiac output, and venous distensibility. More than half of the cases reported during pregnancy are associated with hereditary telangiectasia. In this case a 36-year-old primigravida presented at 24 weeks of gestation with new onset hemoptysis and dyspnea. A PAVM was noted in the right lo...

متن کاملRecurrent brain abscess: manifestation of pulmonary arteriovenous fistula and hereditary hemorrhagic telangiectasia.
A unique case of recurrent brain abscess as the primary manifestation of pulmonary arteriovenous fistula is presented. In the absence of hematologic abnormalities and characteristic physical findings, the diagnosis of pulmonary arteriovenous fistula is particularly elusive. Patients with brain abscess must be carefully evaluated for the presence of pulmonary arteriovenous fistula or hereditary ...

Hereditary hemorrhagic telangiectasia (HHT) is a familial angiodysplastic disorder. Dermal, mucosal, and visceral vascular lesions of this disorder are well known. However, central nervous system (CNS) manifestations, occurring in as many as one-third of patients, have not been well appreciated until recently. The etiology of neurologic symptomatology includes hypoxemia or ischemia secondary to...
