Stroke and Transient Ischemic Attacks of the Brain and Eye

Deep venous drainage occurs via the internal cerebral, basal, or precentral cerebellar veins through the vein of Galen, as opposed to cortical (superficial) venous outflow. In about 20% of AVMs, saccular aneurysms occur on the feeding arteries or within the nidus itself. AVMs with one or more aneurysms are more likely to (re)rupture: the annual risk of bleeding is as high as 7%, against the usual rate of 2–3% per year for AVMs without associated aneurysm.

Veins of the cerebellum: The cerebellar veins constitute the superior and inferior cerebellar veins. The superior group of veins drain into the straight, transverse, and superior petrosal venous sinuses. The inferior cerebellar veins drain into the straight or sigmoid sinus (median vessels), or the inferior petrosal and occipital sinuses (lateral vessels).

Veins draining the cerebral hemisphere consist of superficial and deep veins. Superficial veins drain the cerebral cortex and end in the neighboring venous sinuses, which are superior cerebral veins, inferior cerebral veins, and superficial middle cerebral veins. Deep veins drain the deeper structures (such as the thalamus, hypothalamus, caudate nucleus, putamen, internal capsule, corpus callosum, and choroid plexus) and join to form two internal cerebral veins and two basal veins. These veins drain into the great cerebral vein (great vein of Galen) that ends in the straight sinus. The cerebellum is drained by the superior and inferior cerebellar veins into the straight sinus and other neighboring venous sinuses.1 The veins from the brain stem drain into the adjoining venous sinuses and inferiorly the veins from the medulla are continuous with the veins of the spinal cord.

Remote cerebellar hemorrhage (RCH) is a rare complication after supratentorial surgery, with an incidence around 0.6%1. Although various risk factors have been investigated to explain the occurrence of RCH after supratentorial surgery, including intra-operative or post-operative cerebrospinal fluid (CSF) loss, hypertension, jugular venous compression during surgery and coagulopathy, the exact mechanisms remain uncertain.1–4 However, most authors suggest removal of the supratentorial mass, or massive CSF loss intra-operation or post-operation causing caudal displacement of the cerebellum, which damaged the cerebellar veins, leading to RCH.2
