“…Our embryological perspective on the venous anatomy derives principally from early work of Dorcas Padget 1. Key contributions were made by Yun Peng Huang,2 3 Raybaud, Lasjaunias, Berenstein, and Ter Brugge 4. From a surgical perspective, the works of Rhoton are essential and freely available online 5.…”

“…Tributaries of the internal cerebral vein classically are subdivided into medial and lateral groups (with respect to the lateral ventricle) 2. Their angiographic locations are much easier to understand when correlated with cross-sectional imaging—particularly post-contrast volumetric T1 and susceptibility-weighted sequences.…”

“…The developmental venous anomaly (DVA) can be seen as a consequence of disturbance in the balance of medullary drainage between superficial and deep systems 2 13–18. In deep draining DVAs, the normal superficial drainage of the pial system is deficient, and instead routes subcortical drainage via medullary veins into the subependymal system.…”

Meaningful contributions to neurointerventional practice may be possible by considering the dynamic aspects of angiography in addition to fixed morphologic information. The functional approach to venous anatomy requires integration of the traditional static anatomic features of the system—deep, superficial, posterior fossa, medullary veins, venous sinuses, and outflow routes into an overall appreciation of how a classic model of drainage is altered, embryologically, or pathologically, depending on patterns of flow—visualization made possible by angiography. In this review, emphasis is placed on balance between alternative venous networks and their redundancy, and the problems which arise when these systems are lacking. The role of veins in major neurovascular diseases, such as dural arteriovenous fistulae, arteriovenous malformations, pulsatile tinnitus, and intracranial hypertension, is highlighted, and deficiencies in knowledge emphasized.

Background and Purpose: Modern management of acute stroke necessitates early diagnosis. To this end, we sought to delineate the radiographic features of focal hemispheric infarction within 5 hours of ictus.Methods: Fifty patients, ages 54-79, with ischemic strokes productive of at least hemiparesis underwent computed tomographic scanning and cerebral angiography (n=38) or carotid ultrasound (n=12). Radiographic lesions were characterized for location, size, and pathophysiology.Results: Acute abnormalities, hypodensity, and mass effect were seen in 56% of scans and confirmed on a second scan 5-7 days later. Intracranial angiographic abnormalities occurred in 61% of patients: arterial occlusions in 45% and delayed arterial filling in 16%. Hemorrhagic infarctions occurred in 26% of second scans and were associated with mass effect (100%) and arterial occlusions (89%). Infarcts with hemorrhagic transformation were larger on both scans than those without (p=0.001). Of four patients with infarctions in watershed territories on the scans, two had middle cerebral artery occlusions on angiography, thereby questioning the specificity of such scan lesions to low-flow states.Conclusions: We conclude that cerebral infarctions are often visible on early scans, but their locations may not be etiologically determinative. The infarcts associated with intracranial arterial occlusions (45%) were of thromboembolic origin, but, given current controversies as to the pathophysiology of lacunar and watershed infarctions, we cannot ascertain the etiology in the remainder. These findings are relevant to the new stroke therapies that require administration in the first hours after infarction. (Stroke 1991^2:1245-1253)
