Following a review of the literature it is possible to demonstrate the "normality" of the so called venous angiomas. They should be named Developmental Venous Anomaly (DVA). They illustrate in their two extreme types (superficial and deep) the hemodynamic equilibrium of the transcortical venous drainage in the periependymal zones. Venous ectasias and varices which can be encountered, associated with DVA constitute an acquired feature in relation to a venous outlet obstacle. The sinus pericranii represents an extracerebral DVA, but also corresponds to a normal variation. As any extreme anatomical variant, each DVA corresponds to a weak situation which may express itself clinically; only rare situations justify a radical treatment.

“…The notion that a DVA can produce symptoms by itself is controversial, but isolated reports have described either obstructive hydrocephalus, venous infarction, hemorrhage, or other symptoms arising from a DVA without another associated vascular abnormality [3,[5][6][7][8][9][10][11][12][13][14][15]. Based on our case and these other isolated reports, it would appear that stenosis or occlusion of one of the venous radicles or the main trunk of the lesion could result in venous hypertension or ischemia.…”

Objective and Importance: Developmental venous anomalies (DVAs) are common congenital anomalies of intracranial venous drainage. In general, it is felt that DVAs replace the normal venous drainage system and, unless associated with another lesion such as a cavernous malformation, should not produce symptoms. The present case raises important questions regarding the potential for DVAs to become symptomatic and the role of venous hypertension in this process.Clinical Presentation: We present the case of a 23-year-old woman who presented with rapidly progressive hemi-parkinsonism consisting of unilateral tremor, micrographia, gait difficulty, and cogwheel rigidity. MRI demonstrated a large DVA draining the region of the contralateral basal ganglia with associated high signal intensity on T2-weighted MR imaging and gadolinium enhancement. Arteriography demonstrated only the DVA with the trunk of the angioma draining forward toward the inferior petrosal sinus instead of into the deep venous system. A focal stricture of the main venous trunk was noted. Retrograde venography confirmed a tight stricture at the entrance of the venous trunk into the cavernous sinus.Conclusions: Although DVAs are generally considered benign variants of normal venous drainage, it is possible that in select cases, venous outflow restriction may result in symptomatic venous hypertension. This may be particularly problematic in the setting of a large DVA when multiple radicular veins drain into a single large venous channel.

“…Considerable risks were involved. We also find these indications in the rather rare new publications (1,2,3,5). We ourselves, referring back to the indications of Norldn (19), would like to expand the indication in this group of patients with a tumour in the posterior cranial fossa.…”

Experience with the Leksell drainage (interventriculostomy) in 21 patients is reported. Apart from an account of the technical details and the diagnostic requirements, the indications are also discussed. Apart from the "classic" indications are in a stenosis or restoration of the aqueduct in non-tumourous processes, we see a second reasonable field of application in subtotally resected posterior fossa tumours, when there is the possibility of a recurrence. In these cases the timely use of drainage can save a further operation. In addition, it can be used to forestall an immediate postoperative occlusion of the aqueduct due to oedema in cases in which a tumour was removed from the rostral part of the fourth ventricle. Compared to the common internal shunt procedures, the Leksell drainage shows a definitely greater functional security, equivalent to the Torkildsen drainage.
