“…TVE of AVMs and venous varices has been reported. 8,17,18 Although TVE is originally performed to ensure complete obliteration of an AVM, it can also be applied to treat venous varices. In TVE, coils are placed in the venous varix to promote thrombosis of the varix; thus, a mass effect may occur due to the coils.…”

Background: Venous varices in the draining vein of arteriovenous malformations (AVMs) can result in compression symptoms. This condition is extremely rare, and its treatments and long-term outcomes are unresolved. Herein, we describe the treatment of a thrombosed venous varix in a draining vein and review the relevant literature. Patient: The patient presented with progressive right-sided hemiparalysis and aphasia. Magnetic resonance imaging revealed flow void accumulation from the corpus callosum to the left ventricle and a 30-mm mass in the left putamen. The patient underwent targeted transarterial embolization to reduce the blood flow to the venous varix and relieve the neurological symptoms. The patient had recovered completely from the right hemiparesis and aphasia 4 years after treatment, with a modified Rankin Scale score of 0. Conclusion: Targeted transarterial embolization for symptomatic venous varix is a palliative treatment that may improve long-term functional outcomes.
