Reconstruction of cerebral cortical veins using silicone tubing

Abstract

A technique for reconstruction of a cerebral cortical vein which has been sacrificed during an interhemispheric or subtemporal surgical approach is described. The method involves the use of silicone tubing. The author's clinical experience in six patients is summarized.

“Squeeze Maneuver” Assisted by Indocyanine Green Videoangiography: Simple Technique to “Resuscitate” Partially Occluded Bridging Veins During Microneurosurgical Operations

“…When the integrity of the vein wall is damaged, on the basis of the size of the defect, methods for definitive repair include wrapping, microsuture, venous reconstruction using the silicone tubing technique or saphenous vein bypass graft, and vein anastomosis. 1,[15][16][17][18][19][20] However, all of these procedures are not useful for collapsed veins with uninjured walls. In these circumstances, a profuse irrigation with isotonic saline solution may be useful to rehydrate the vein wall in order to restore its normal diameter.…”

Retinotopy with coordinates of lateral occipital cortex in humans

“…Note that the lateral occipital cortex can also be used for artificial vision in patients with lesions in the medial occipital cortex or the development of bridging veins. 21 When instruments for extracranial stimulation, such as a transcranial magnetic stimulator, and retinotopy of the lateral occipital cortex become more precise, artificial vision through the extrastriate cortex would be possible without invasiveness.…”

Reconstruction of the superior sagittal sinus with silicone tubing

“…Marks, et al, 5 performed an SSS bypass operation in 1986. In 1987 Sakaki, et al, 8 succeeded for the first time in reconstructing cortex veins with silicone tube. Since that time, reconstruction of the SSS and its main drainage veins has occasionally been reported.…”

“…Since that time, reconstruction of the SSS and its main drainage veins has occasionally been reported. 2,8,10,11 At present, the main materials used to repair vessels are the autogenous great saphenous vein, neck superficial veins, and artificial blood vessels such as Dacron and polytetrefluoroethylene, which are suitable for the larger diameter of arterial system, whereas silicone tubing is suitable for dural venous sinuses and veins. Silicone is a form of high polymer with an elastic body, which is formed by inorganic and organic molecules.…”
