An early venous abnormality: a potential cause of arteriovenous malformation recurrence

Abstract

In adults, complete surgical resection of arteriovenous malformations (AVMs) is generally curative. Recurrence of AVMs is extremely rare and most often delayed over many years. The authors report the case of a man in his 20s with rapid AVM recurrence and dual blood supply from the dura and intracerebral vessels. Early recurrence of the AVM allowed documentation of the early events associated with this recurrence. This was evidenced by the first appearance of an early vein without any signs of abnormal vasculature, suggesting that abnormality of the venous drainage system might be an inciting event in the recurrence and perhaps genesis of AVMs.

Cerebral Arteriovenous Malformation Recurrence After Complete Surgical Excision in an Adult: Case Report and Review of the Literature

“…Only sporadic case reports/series exist; just 18 cases have been reported in the English literature over the last 30 years (Table 1) [9,[13][14][15][16][17][18][19][20][21][22][23][24]. Age at initial presentation ranged from 19 to 51, recurrence was observed from several months to 16 years after resection with all except one discovered within 10 years.…”
