Abstract: | For malignant cerebral venous sinus thrombosis (CVST) complicated with cerebral hernia, decompressive craniectomy may be life-saving, and thrombectomy combined with thrombolysis may obtain better outcomes. This report describes an approach performed on 2 patients diagnosed with CVST combined both thrombectomy and thrombolysis with decompressive craniectomy through incising the superior sagittal sinus. The general procedure of the operation is as follows. The anterior part of the superior sagittal sinus was exposed firstly. After cutting the dura matter for decompression, a superior sagittal sinus incision was taken to detect sinus thrombus. In order to facilitate hemostasis during detecting the sagittal sinus, 2 silk sutures were sutured along the incision. The incision was 5 millimeters long approximately along the middle line of the front third of the superior sagittal sinus. A silicone intubation was inserted in the sinus through the incision. Thrombus was seen in the suction tube. At a depth of about 10 cm, while it is difficult to penetrate the tube, we used the gelatin sponge to cover the sinus incision and fixed the suture lines after cross-knotting. The silicone intubation was drawn out through the forehead and connected to external micro pump for injecting anticoagulant drugs, then cut the dura mater into star-shaped and discard bone flap for decompression. Absorbable artificial dura mater was used to repair bilateral dura mater, respectively. At last, connect the catheter to the micro pump for pumping anticoagulant. After operation, the 2 patients received thrombolysis through the catheter placed in the sinus. Both of them recovered well. There was no incision-related bleeding occurred after surgery. Both the patients achieved incredibly good outcomes. For patients with malignant cerebral venous sinus thrombosis, acute cerebral hernia or cerebral hernia tendency, it may be an effective approach combined both thrombectomy and thrombolysis with decompressive craniectomy through incising the superior sagittal sinus. |
