Congenital vascular malformation represents a group of anomalous vascular structures caused by defective development through various stages of embryogenesis. In 1988 a workshop for this unique field of vascular pathology was held in Hamburg, Germany, and new classification was evolved on the basis of consensus through this workshop. Congenital vascular malformations are now classified based on ...
The vast majority of cerebral vascular malformations reported in the antenatal literature are aneurysmal malformations of the vein of Galen. Other types of intracranial vascular malformations are exceptional in fetuses. The authors present a case of prenatal diagnosis of intracranial pial arteriovenous fistula, not involving the vein of Galen and not showing abnormal intracranial anatomic featu...
BACKGROUND Recent radiological studies have shown that arteriovenous malformations with impaired venous drainage may be susceptible to hemorrhage. To evaluate this hypothesis using a hemodynamic approach, we measured intravascular pressure during surgery in three patients with arteriovenous malformation. SUMMARY OF REPORT In three patients we measured intravascular pressures in the draining v...
