Two cases of complete sagittal sinus occlusion with multiple brain hemorrhages, elevated intracranial pressure, and disseminated intravascular coagulation are described. These patients were successfully managed using pentobarbital-induced coma to ameliorate intracranial pressure elevation. This therapy was combined with monitoring of intracranial pressure and intermittent drainage of cerebrospinal fluid to further control intracranial pressure elevations. Thrombus and coagulopathy resolved with pentobarbital alone in one patient and after pentobarbital plus heparin therapy in the second patient. It is suggested that cases of severe distal sagittal sinus thrombosis with brain hemorrhage and intracranial hypertension may benefit from combined pentobarbital coma and intraventricular drainage. This allows for stabilization of bleeding tendencies before instituting heparin therapy when necessary. Management of sagittal sinus thrombosis with barbiturates or ventricular drainage is best performed in an ...

Background and Purpose We sought to compare the safety and efficacy of direct urokinase thrombolysis with systemic heparin anticoagulation for superior sagittal sinus thrombosis (SSST). Methods At University at Buffalo (NY) and University of Texas (Dallas, Houston), we reviewed 40 consecutive patients with SSST, treated with local urokinase (thrombolysis group) or systemic heparin anticoagulation (heparin group). The thrombolysis group (n=20) received local urokinase into the SSS followed by systemic heparin anticoagulation. The heparin group (n=20) received systemic heparin anticoagulation only. Neurological dysfunction was rated as follows: 0, normal; 1, mild (but able to ambulate and communicate); 2, moderate (unable to ambulate, normal mentation); and 3, severe (unable to ambulate, altered mentation). Results Age (P=0.49), sex (P=0.20), baseline venous infarction (P=0.73), and predisposing illnesses (P=0.52) were similar between the thrombolysis and heparin groups. Pretreatment neurological

Intracranial hemorrhage is a feared and limiting complication of thrombolytic therapy. Three patients in our thrombolysis group had pretreatment hemorrhagic infarcts. No worsening of these hemorrhages or progressive neurological deficits were identified in these patients. Two patients in our thrombolysis group developed hemorrhagic complications (unrelated to the venous thrombosis). We reviewed 96 cases of SSST (including our series) treated with local thrombolysis (urokinase, n=72; tissue plasminogen activator, n=23; streptokinase, n=1), as summarized in Table 3. Eighty-eight of these patients (92%) had a good recovery, 1 patient died, and 5 patients had worsening of intracranial hemorrhage without a fatal outcome (Table 3). Seven patients developed new hemorrhages (retroperitoneal bleed, n=3; intracerebral hemorrhage, n=2; subdural hemorrhage, n=1; hematuria, n=1) (Table 3). Horowitz et al7 described 13 patients, 4 of whom had pretreatment brain hemorrhages (Table 3). No worsening was seen ...

After systemic heparin anticoagulation, a 24-French arterial cannula (Endoarterial Return Cannula, Heartport) was placed atraumatically in the right common femoral artery with direct surgical exposure, and a 28-French venous cannula was advanced into the right atrium from the right femoral vein. A centrifugal pump was placed between the venous cannula and the venous reservoir to increase venous drainage. The pump prime consisted of 1200 cc of Normosol (Abbott Laboratories, North Chicago, IL), 250 cc of 20% mannitol, 500 cc of 6% hydroxyethyl starch, 50 mEq of sodium bicarbonate, and 5000 U of heparin. As CPB was slowly initiated, TEE imaging at 45 cm from the teeth in the horizontal plane immediately demonstrated an echogenic region in the descending thoracic aorta apparently separated from the aortic lumen by a membrane. These TEE findings were believed to strongly suggest an evolving aortic dissection, and CPB was immediately discontinued. The observed TEE evidence of dissection rapidly ...
Although myriad neurologic complications have been reported in patients with HIV infection, thromboembolic phenomena have been limited to scattered reports. Most of these reports have been anecdotal and have implicated lupus anticoagulant, anticardiolipin antibody, and protein S deficiency (Although myriad neurologic complications have been reported in patients with HIV infection, thromboembolic phenomena have been limited to scattered reports. Most of these reports have been anecdotal and have implicated lupus anticoagulant, anticardiolipin antibody, and protein S deficiency (1-3).

Summary: We present a novel application of a transvascular rheolytic thrombectomy system in the treatment of symptomatic dural sinus thrombosis in a 54-year-old woman with somnolence and left-sided weakness. The diagnosis of bilateral transverse and superior sagittal sinus thrombosis was made and the patient was treated with anticoagulant therapy. After an initial period of improvement, she became comatose and hemiplegic 8 days after presentation. After excluding intracerebral hemorrhage by MR imaging, we performed angiography and transfemoral venous thrombolysis with a hydrodynamic thrombectomy catheter, followed by intrasinus urokinase thrombolytic therapy over the course of 2 days. This technique resulted in dramatic sinus thrombolysis and near total neurologic recovery. Six months after treatment, the patient showed mild cognitive impairment and no focal neurologic deficit. Our preliminary experience suggests that this technique may play a significant role in the endovascular treatment of ...
OBJECTIVE To explore the controversial issue of anticoagulant therapy and indications for surgery in association with severe sinus thrombosis. METHODS During the last 4 years, we have treated three patients with severe sinus thrombosis of the dural sinuses. All three patients received systemic anticoagulant therapy and, after experiencing neurological deterioration, underwent open thrombectomy and local thrombolysis. After the operation, aggressive intensive care was given and included cerebral perfusion monitoring, barbiturate administration, hyperventilation, and osmotherapy. The treatment was guided by repeated neuroradiological investigations. RESULTS All three patients returned to their normal lives. CONCLUSION Intracranial sinus thrombosis, even in the worst neurological state, should be treated aggressively. A cornerstone in treatment is systemic anticoagulant therapy and repeated neuroradiological studies. When, despite adequate anticoagulant therapy and intensive care, neurological
A 15-year-old adolescent was admitted to the emergency department after a car accident because of severe traumatic brain injury. Upon arrival, he was sedated and intubated because of a Glasgow Coma Scale score below 8. He had isocoria with reactive pupils. An occipital puncture wound (diameter 2 cm) was profusely bleeding. His blood pressure was 85/45 mm Hg. Laboratory values identified a haemoglobin level of 4.6 mmol/l. A CT scan of the brain demonstrated a comminuted-depressed fracture of the parietal bone in the midline with a rupture of the superior sagittal sinus (SSS) and secondary thrombosis (figure 1). After prompt resuscitation including packed blood cells, a large biparietal decompressive craniectomy was performed centred at the skull fracture anticipating on intracranial hypertension due to venous oedema or infarction. The sinus haemorrhage was initially packed with haemostatic material and manually compressed with cottonoids and spatula until the roof of the sinus was reconstructed ...
Migraine is a debilitating neurological disorder involving abnormal trigeminovascular activation and sensitization. However, the underlying cellular and molecular mechanisms remain unclear. A rat model of conscious migraine was established through the electrical stimulation (ES) of the dural mater surrounding the superior sagittal sinus. Using patch clamp recording, immunofluorescent labelling, enzyme-linked immunosorbent assays and western blot analysis, we studied the effects of ES on sensory neuronal excitability and elucidated the underlying mechanisms mediated by voltage-gated ion channels. The calcitonin gene-related peptide (CGRP) level in the jugular vein blood and the number of CGRP-positive neurons in the trigeminal ganglia (TGs) were significantly increased in rats with ES-induced migraine. The application of ES increased actional potential firing in both small-sized IB4-negative (IB4−) and IB4+ TG neurons. No significant changes in voltage-gated Na+ currents were observed in the ES-treated
A rheolytic thrombectomy is a procedure designed to remove clots. A special pump delivers high-pressure saline to the tip of the catheter.
In cases of advanced-stage temporal bone carcinoma, both extensive resections and high-dose irradiation are recommended (6). Although the prognosis of a patient with a T4/stage 4 lesion is grim, survival is better when clear surgical margins can be achieved (5). When an individual situation is assessed, the justified use of radical surgery must be weighted against potential morbidities that may result from facial nerve or ICA resection or the need to sacrifice the dominant sigmoid sinus, as in the present case.. If a dural sinus is completely occluded because of tumor invasion, adequate venous collaterals have developed and the affected sinus can be excised without ensuing venous complications (7). If the affected sinus is still patent, however, the risk of sinus occlusion is high, especially in the posterior two-thirds of the superior sagittal sinus and the dominant transverse or sigmoid sinus; this situation entails the risk of intracranial hypertension and venous infarction (3, 4, 7). ...
Cerebral venous sinus thrombosis (CVST) is the presence of acute thrombosis (a blood clot) in the dural venous sinuses, which drain blood from the brain. Symptoms may include headache, abnormal vision, any of the symptoms of stroke such as weakness of the face and limbs on one side of the body, and seizures. The diagnosis is usually by computed tomography (CT/CAT scan) or magnetic resonance imaging (MRI) employing radiocontrast to demonstrate obstruction of the venous sinuses by thrombus. Treatment is with anticoagulants (medication that suppresses blood clotting), and rarely thrombolysis (enzymatic destruction of the blood clot). Given that there is usually an underlying cause for the disease, tests may be performed to look for these. The disease may be complicated by raised intracranial pressure, which may warrant surgical intervention such as the placement of a shunt. Nine in ten people with sinus thrombosis have a headache; this tends to worsen over the period of several days, but may also ...
Commencing at the foramen cecum, through which it receives emissary veins from the nasal cavity, it runs from anterior to posterior, grooving the inner surface of the frontal, the adjacent margins of the two parietal lobes, and the superior division of the cruciate eminence of the occipital lobe. Near the internal occipital protuberance, it drains into the confluence of sinuses and deviates to either side (usually the right). At this point it is continued as the corresponding transverse sinus. The superior sagittal sinus is usually divided into three parts: anterior (foramen cecum to bregma), middle (bregma to lambda), posterior (lambda to confluence).[1] It is triangular in section, narrow in front, and gradually increases in size as it passes backward. Its inner surface presents the openings of the superior cerebral veins, which run, for the most part, obliquely forward, and open chiefly at the back part of the sinus, their orifices being concealed by fibrous folds; numerous fibrous bands ...
Central venous sinus thrombosis (CVT) and venous cerebral infarction are important differentials for the causes of headache or seizure in the young person, particularly in the young woman who is/has recently been pregnant. It is probably the most rare form of stroke, but - when it happens - the patient usually will end up in ICU, and the critical care trainee will probably see more of this than any other specialty. This has come up in Question 26 from the second paper of 2015. Dural sinus thrombosis in that question was associated with pregnancy (as typically they are) and the question could easily be shoved into the O&G section, but the specific information requested from the candidates (outline the management priorities, etc) was more neurological/neurosurgical in nature.
... occurs when a blood clot forms in the brains venous sinuses. This prevents blood from draining out of the brain. As a result, blood cells may break and leak blood into the brain tissues, forming a hemorrhage. This chain of events is part of a stroke that can occur in adults and children of all ages.

Cerebral venous sinus thrombosis (CVST) is a rare clinicopathological entity. The incidence of CVST in children and neonates has been reported to be as high as 7 cases per million people, whereas in adults the incidence is 3-4 cases per million. The predisposing factors to this condition are mainly genetic and acquired prothrombotic states and infection. The clinical picture of CVST is nonspecific, highly variable, and can mimic several other clinical conditions. Diagnosis of CVST is established with the implementation of neuroimaging studies, especially MR imaging and venography. Identification and elimination of the underlying cause, anticoagulation, proper management of intracranial hypertension, and anticonvulsant prophylaxis constitute cornerstones of CVST treatment. Newer treatment strategies such as endovascular thrombolysis and decompressive craniectomy have been recently used in the treatment of patients with CVST with variable success rates. Further clinical research must be performed to
Cerebral venous sinus thrombosis in children is increasingly recognized as diagnostic tools and clinical awareness has improved. It is a multifactorial disease where prothrombotic risk factors and predisposing clinical conditions usually in combination constitute the underlying etiology. Clinical features range from headache, seizures to comatose state. Although symptomatic treatment involving control of infections, seizures and intracranial hypertension is uniform, use of anticoagulation and local thrombolytic therapy is still controversial. Morbidity and mortality can be significant and long-term neurological sequelae include developmental delay, sensorimotor and visual deficits and epilepsy.

N2 - PURPOSE: To gain a preliminary understanding of the role of thrombolytic therapy for the thrombosed dural sinus, we retrospectively reviewed our initial experience. METHODS: Seven patients, ages 25 to 71, who presented with symptomatic dural sinus thrombosis and who failed a trial of medical therapy were treated with direct infusion of urokinase into the thrombosed sinus. Patients received urokinase doses ranging from 20 000 to 150 000 U/h with a mean infusion time of 163 hours (range 88 to 244 hours). RESULTS: Patency of the affected dural sinus was achieved with antegrade flow in all patients. Six patients either improved neurologically over their prethrombolysis state or were healthy after thrombolysis; one of them required ...
Dural venous sinus thrombosis is a rare and potentially devastating disease. Several predisposing factors exist, including oral contraceptive therapy and colitis. First-line therapy consists of systemic anticoagulation. If first-line therapies fail, more aggressive endovascular therapies may be performed. We report our initial experience with the Solitaire FR device for treatment of refractory symptomatic dural venous sinus thrombosis.. ...
Venous thrombosis may occur in any or all of the following venous structures: the venous sinuses, superficial cortical veins, or the deep venous system. Typically, superficial cortical vein thrombosis is only seen in the seen in the setting of venous sinus thrombosis, and thrombosis of the deep venous system is relatively rare (albeit very serious). Approximately 1% of all strokes occur secondary to venous sinus thrombosis, and the most frequently thrombosed sinuses are the superior sagittal sinus, followed by the transverse, sigmoid and cavernous sinuses. There are numerous conditions associated with venous sinus thromboses and broadly speaking, these tend to be divided into septic or non-septic etiologies. One fourth of cases are of unknown cause. It is common for hemorrhage to be present within areas of venous infarction, whereas it is relatively uncommon to occur with arterial occlusion and infarction. In general, hemorrhagic cerebral infarctions are classified as primary or secondary with ...
Cerebral venous thrombosis is rare and often under diagnosed in children with nephrotic syndrome. MRI with venography is an essential tool in its diagnosis. Both early diagnosis and the commencement of anticoagulation are paramount for a good outcome. An 8 year old boy diagnosed with steroid dependent nephrotic syndrome with 12 relapses in the 2 years since diagnosis, presents and is admitted for another relapse following an intercurrent illness. Symptoms and signs at the time of admission are lethargy, cough, vomiting, abdominal pain, headache, generalised oedema and ascites. He is treated with high dose steroids and goes into remission within the next 3 days. However, he continues to complain of a headache not improved with analgesia. Magnetic Resonance Imaging (MRI) followed by venography are performed and the diagnosis of a dural sinus thrombosis is made. Initial neurology is intact, however, he develops signs of raised intracranial pressure and requires transfer to a tertiary centre. He is ...
