The experience of simultaneous endovascular occlusion of arteriovenous malformation and saccular aneurism in a parturient woman

Abstract

The clinical case of simultaneous endovascular bloodstream exclusion of arteriovenous malformation and saccular aneurysm in parturient woman is presented. Onyx liquid adhesive composition and monospiral aneurysm occlusion technique were used. Patient X., 31, was hospitalized to the clinic on the 10th day of the postpartum period. From the anamnesis: twice (at 20th and 27th weeks of pregnancy) patient suffered intraventricular hemorrhage due to the rupture of arteriovenous malformation in the posterior third of the corpus callosum, left lateral ventricle and left parietal lobe of the brain. After the first hemorrhage a conservative treatment tactic was determined, given the high risk of complications associated with the surgical intervention for the mother and fetus. After the second hemorrhage endovascular embolization of malformation was suggested, however, the patient and her husband refused surgery, preferring conservative therapy with subsequent surgical treatment after delivery. In addition to the malformation, according to the data of selective cerebral subtraction angiography multiple cerebral saccular aneurysms of the left Anterior Cerebral – Anterior Communicating Artery and 2 Anterior Cerebral Artery aneurysms (A2-A2, A3-A4-segments) on the right side were diagnosed. Endovascular subtotal embolization of arteriovenous malformation and occlusion of the right Anterior Cerebral Artery (A2-A3-segment) saccular aneurysm were performed during the operation. A control angiographic examination after 3 months showed a complete exclusion of these arteriovenous malformation and saccular aneurysm and disappearance of all aneurysms of the left Anterior Cerebral Artery – Anterior Communicating Artery and right Anterior Cerebral Artery (A3-A4-segment).
