Object. The goal of this study was to document the hazards associated with pseudotumor cerebri resulting from transverse sinus thrombosis after tumor resection. Dural sinus thrombosis is a rare and potentially serious complication of suboccipital craniotomy and translabyrinthine craniectomy. Pseudotumor cerebri may occur when venous hypertension develops secondary to outflow obstruction. Previous research indicates that occlusion of a single transverse sinus is well tolerated when the contralateral sinus remains patent.Methods. The authors report the results in five of a total of 107 patients who underwent suboccipital craniotomy or translabyrinthine craniectomy for resection of a tumor. Postoperatively, these patients developed headache, visual obscuration, and florid papilledema as a result of increased intracranial pressure (ICP). In each patient, the transverse sinus on the treated side was thrombosed; patency of the contralateral sinus was confirmed on magnetic resonance (MR) imaging. Four patients required lumboperitoneal or ventriculoperitoneal shunts and one required medical treatment for increased ICP. All five patients regained their baseline neurological function after treatment. Techniques used to avoid thrombosis during surgery are discussed.Conclusions. First, the status of the transverse and sigmoid sinuses should be documented using MR venography before patients undergo posterior fossa surgery. Second, thrombosis of a transverse or sigmoid sinus may not be tolerated even if the sinus is nondominant; vision-threatening pseudotumor cerebri may result. Third, MR venography is a reliable, noninvasive means of evaluating the venous sinuses. Fourth, if the diagnosis is made shortly after thrombosis, then direct endovascular thrombolysis with urokinase may be a therapeutic option. If the presentation is delayed, then ophthalmological complications of pseudotumor cerebri can be avoided by administration of a combination of acetazolamide, dexamethasone, lumbar puncture, and possibly lumboperitoneal shunt placement.

Dural Arteriovenous Fistulas

The authors report dural sinus thrombosis diagnosed in 2 patients based on noninvasive imaging results, which were revealed to be dural arteriovenous fistulas (DAVFs) diagnosed using digital subtraction (DS) angiography. The first patient was a 63-year-old man who presented with headaches. Magnetic resonance venography was performed and suggested dural sinus thrombosis of the left transverse sinus and jugular vein. He was administered warfarin anticoagulation therapy but then suffered multiple intracranial hemorrhages. A DS angiogram was requested for a possible dural sinus thrombectomy, but the DS angiogram revealed a DAVF. The patient underwent serial liquid embolization with complete obliteration of the DAVF. The second patient, an 11-year-old boy, also presented with headaches and was diagnosed with dural sinus thrombosis on MR imaging. A DS angiogram was also requested for a possible thrombectomy and revealed a DAVF. This patient underwent serial liquid embolization and eventual operative resection. These reports emphasize that different venous flow abnormalities can appear similar on noninvasive imaging and that proper diagnosis is critical to avoid contraindicated therapies.

✓ Cerebral venous sinus thrombosis is often difficult to manage. Treatment options include systemically delivered anticoagulation therapy or chemical thrombolysis. Targeted endovascular delivery of thrombolytic agents is currently a popular option, but it carries an increased risk of hemorrhage. These strategies require significant time to produce thrombolysis, often in a patient with a rapidly deteriorating neurological condition. Rapid mechanical recanalization with thrombectomy is therefore very attractive; this procedure provides rapid recanalization with no increased risk of hemorrhage from use of thrombolytic agents. Nevertheless, the rheolytic catheter is large and stiff and may not be able to navigate tortuous intracranial vascular anatomy. The authors present their experience with direct dural sinus mechanical thrombectomy performed using the rheolytic catheter via a transcranial route. Two patients with dural sinus thrombosis and rapidly deteriorating levels of consciousness underwent unsuccessful attempts at mechanical thrombolysis via the usual transfemoral route. Through a burr hole over the dural sinus, mechanical thrombectomy was subsequently performed using the thrombectomy catheter. Sinus patency was restored following treatment and both patients demonstrated neurological recovery. Hemorrhage or a rapidly deteriorating neurological condition may preclude the use of systemic or locally delivered thrombolytic agents for the treatment of cerebral venous sinus thrombosis. Mechanical thrombectomy may be the treatment of choice in these circumstances. In patients with limited transfemoral access, a transcranial approach may be used to access the cerebral dural sinuses and thrombectomy may be safely and effectively performed. Further evaluation of this therapy is warranted.

Dural Sinus Thrombosis

Dural sinus thrombosis is a rare complication after posterior fossa surgery, particularly in cerebellar tumour surgery. The authors describe the case of a young male patient who presented a postoperative neurological deterioration due to transverse sinus thrombosis after surgery for cerebellar medulloblastoma. He was treated by mechanical clot thrombectomy using an endovascular catch system technique without anticoagulation therapy. Final angiographic recanalization was obtained. This kind of endoluminal mechanical revascularization is an efficacious method to treat dural sinus thrombosis during perioperative time but speed in diagnosis is crucial for clinical outcome.

Object. Transvenous embolization is effective in the treatment of an intracranial dural arteriovenous fistula (DAVF). Access to the fistula via the internal jugular vein (IJV) may be limited by associated dural sinus thrombosis; a transcranial approach has been developed for venous embolization in such a situation. The authors report their experiences with the use of a transcranial approach for venous embolization of DAVFs. Methods. Ten patients with DAVFs underwent craniectomy and embolization procedures in which direct sinus puncture was performed. The DAVFs were located inside the dura mater that constituted the walls of the transverse sinus in five cases, the superior sagittal sinus in four cases, and the superior petrosal sinus in one case. All DAVFs drained directly into a sinus with secondary reflux into leptomeningeal veins. In all cases, the fistula could not be accessed from the IJVs. Craniectomy was performed in an operating room and, in seven cases, subsequent enlargement of the craniectomy was required. Sinus catheterization was performed after the patient had been transferred to the angiography room. The DAVFs were embolized using coils only in five patients, glue only in two patients, and both coils and glue in three patients. Angiographic confirmation that embolization of the fistula was successful was obtained in all cases. A transient complication occurred during the first case after sinus catheterization was attempted in the operating room. Conclusions. The transcranial approach allows straightforward access to DAVFs located on superficial dural sinuses that are inaccessible from the IJVs. The effectiveness of this approach is similar to that of the standard retrograde venous approach. The correct location and adequate extent of the craniectomy are essential for success to be achieved using this technique.

✓ Dural sinus thrombosis has been hypothesized as a possible cause of dural arteriovenous fistulas (AVF's). The pathogenesis and evolution from thrombosis to actual development of an AVF are still unknown. To study dural fistula formation, a surgically induced venous hypertension model in rats was created by producing an arteriovenous shunt between the carotid artery and the external jugular vein. The external jugular vein beyond the anastomosis was ligated 2 to 3 months after surgery and angiography was performed to identify any new acquired AVF's. Forty-six male Sprague-Dawley rats, each weighing approximately 300 gm, were used for this study. In Group I, 22 rats underwent a common carotid artery anastomosis to the external jugular vein, which is the largest draining vein from the transverse sinus via the posterior facial vein, followed by proximal external jugular vein ligation. In Group II, 13 rats underwent the same surgical procedure, followed by contralateral posterior facial vein occlusion. Group III served as the control group, in which 11 rats underwent only unilateral external jugular vein occlusion with or without contralateral posterior facial vein occlusion. The shunts in Groups I and II were ligated at 2 to 3 months following surgery, and transfemoral angiography was performed immediately before and after occlusion. New acquired AVF's had developed in three rats (13.6%) in Group I, three rats (23.1%) in Group II, and no rats (0%) in Group III. One of these newly formed fistulas was located at the dural sinus, analogous to the human dural AVF. The other five were located in the subcutaneous tissue, including the face and neck. The dural AVF in the rat was present on follow-up angiography at 1 week after the bypass occlusion. It is concluded that chronic venous hypertension of 2 to 3 months' duration, without associated venous or sinus thrombosis, can induce new AVF's affecting the dural sinuses or the subcutaneous tissue.

Abstract OBJECTIVE Dural sinus thrombosis (DST) is an uncommon cause of stroke. The safest and most effective therapy for DST has not been conclusively identified. METHODS A retrospective chart review of data for 31 patients who were treated for DST at our institution between 1992 and 2001 was performed. Four treatment strategies were identified, i.e., 1) medical observation only, 2) systemic anticoagulation (AC) therapy with heparin, 3) endovascular chemical thrombolysis with urokinase or tissue plasminogen activator and concurrent systemic AC therapy, and 4) mechanical endovascular clot thrombolysis with concurrent systemic AC therapy. Complications and clinical outcomes were assessed for each group. RESULTS Patients treated solely with medical observation fared the worst; four of five patients experienced intracranial hemorrhagic complications, and only two of five exhibited clinical improvement. Patients who received systemic AC therapy experienced no hemorrhagic complications, even when pretreatment hemorrhage was present; 75% (six of eight patients) exhibited improvement with AC therapy alone. Chemical thrombolysis was very effective in restoring sinus patency (90% of patients); however, 30% of patients (3 of 10 patients) experienced hemorrhagic complications. Sixty percent of patients (6 of 10 patients) who underwent chemical thrombolysis exhibited clinical improvement. Patients who underwent mechanical thrombectomies demonstrated a low hemorrhagic complication rate, and most (88%) made good recoveries. CONCLUSION Therapy directed at the underlying clot in DST must begin without delay. Our results suggest that supportive medical management of DST, without therapy directed at the clot or clotting process, is not effective. Systemic AC therapy, even in the presence of intracerebral hemorrhage, seems to be safe. Heparin can be safely titrated to yield partial thromboplastin times of 60 to 70 seconds. Chemical clot thrombolysis is efficacious in opening occluded sinuses but may cause intracranial hemorrhage. We currently recommend either systemic AC therapy or systemic AC therapy in conjunction with mechanical clot thrombectomy as a safe effective treatment for DST.
