Operative techniques for management of lesions involving the dural venous sinuses.
The basic principles of vascular surgery, adequate exposure, proximal and distal control of hemorrhage, and meticulous approximation of endothelial surfaces should be adhered to in the management of lesions of the dural venous sinuses. Modification of conventional vascular techniques must be made since the major dural venous sinuses are essentially non collapsible and non mobilizable because of the entry of cortical veins at frequent intervals along their course. These problems can be solved by occlusion of the proximal and distal segments of the sinus from within the lumen and by use of a shunt consisting of a siliconized non-collapsible tube with an inflatable balloon cuff at each end. Saphenous vein autografts are used if primary repair is impossible because of loss of tissue. Using these techniques, a patency rate of 91% and a mortality rate of 9% were achieved in eleven cases involving the posterior sagittal and transverse sinuses.
