✓ In this study of 110 cranial cavities from adult cadavers, the superior sagittal sinus was found to divide into two channels. In most cases, the division was associated with a dural partition. Essentially, the variations as observed in this study could be grouped into three types: Type 1 includes those specimens in which the sagittal sinus drains into one lateral sinus and the straight sinus into the other, with no connection between the two. Type 2 includes those specimens in which the superior sagittal sinuses and the straight sinus fork, and the forks from both sinuses join to form the lateral sinuses. Type 3 includes those specimens in which a confluence of sinuses exists, varying from a common pool to merely a potential confluence, depending upon the presence of pads, incomplete partitions, and complete partitions of dura mater. Rare findings previously not reported consist of double straight sinuses draining into one transverse sinus; the superior sagittal sinus dividing into three channels with two transverse sinuses on one side; a transverse sinus originating from a tentorial vein; and drainage of a tentorial vein into the confluence of sinuses.

✓ During an anatomical study of 295 cerebral dural sinuses obtained from cadavers, polypoid nodules were found in the superior sagittal sinus in two specimens. In 23 additional specimens, similar but smaller nodules were encountered in the transverse sinuses. The polyps in the superior sagittal sinuses were of sufficient size to cause a dilatation of the sinuses at the level of the masses. The histological evidence indicates their origin to be Pacchionian granulations.

Transverse Sinuses

The superior sagittal sinus is the largest of the venous sinuses. It receives blood from the frontal, parietal, and occipital superior cerebral veins and the diploic veins, which communicate with the meningeal veins. The superior sagittal sinus drains into the transverse sinuses. Central nervous system tumors like meningioma, glomus tumor, and meduloblastoma, often directly compress the veins and sinuses of the brain. Major sites of the occlusion include superior sagittal sinus (SSS) and transverse sinus. Initial days cerebral venous sinus thrombosis (CVST) was diagnosed only on autopsy. Since the advent of modern investigative modalities like magnetic resonance Imaging (MRI), Computerised Tomography Angiography (CTA) and Magnetic Resonance Venography (MRV), more and more cases are being diagnosed confidently.

Subacute Thrombosis

Cerebral venous sinus thrombosis is an important pathology with various clinical symptoms. Early detection of thrombosis is very important for the improvement of the prognosis. The aim of this study was to calculate the diagnostic value of T2-weighted sequences of magnetic resonance imaging (MRI) in detecting subacute thrombosis. All patients that were suspected of having subacute cerebral venous sinus thrombosis and were referred to the emergency center of Kashani hospital (between September 2018 and September 2019) were entered into the study. Magnetic resonance venography (MRV) and T2-weighted MRI were accomplished for each patient. The sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of MRI using MRV as the reference method were calculated. A total of 630 patients were entered into the study. A positive subacute venous sinus thrombosis was detected in the MRV of 53 patients; consequently, the sensitivity of 60%, the specificity of 80%, the PPV of 21%, and the NPV of 96% were calculated. MRI was highly specific for detecting the subacute thrombosis of superior sagittal sinus, transverse sinuses, sigmoid sinuses, and straight sinus (specificity>94%). A substantial agreement was detected between MRI and MRV in distinguishing thrombosis of superior sagittal sinus, transverse sinuses, sigmoid sinuses, and straight sinus (kappa>0.6). T2-weighted MRI is a specific method in detecting cerebral venous sinus thrombosis. In a patient with signs of thrombosis in the T2-weighted sequence, additional workups are highly suggested to rule out the pathology.

✓ There is a wide variety of disorders associated with thrombosis of the superior sagittal sinus (SSS), including infectious disease, noninfectious conditions such as vasculitis and hypercoagulable states, and complications arising from pregnancy or use of oral contraceptive medications. Despite these well-defined associations, approximately 25% of the cases remain idiopathic. In this article the authors describe a patient who was found to have SSS thrombosis while experiencing a thyrotoxic phase of Graves disease. The patient presented with intracerebral hemorrhage, subarachnoid hemorrhage, seizure, coma, a raised fibrinogen concentration, low protein C activity, and atrial fibrillations. Thrombolysis was successfully performed despite the coexistence of thrombosis and intracranial hemorrhage. Patients with thyrotoxicosis and a diffuse goiter may be predisposed to the development of SSS thrombosis, as a result of hypercoagulation and stasis of local venous blood flow. In the present case, a patient in whom thrombosis coexisted with intracranial hemorrhage was successfully treated using thrombolytic therapy.

AbstractDural arteriovenous fistulas (DAVFs) located within superior sagittal sinus (SSS) wall with direct cortical venous drainage are rare. They are also known as variant DAVF (vDAVF) and form a special subgroup of DAVFs. Their chance of presenting with aggressive features is high compared with transverse sigmoid sinus fistula. They drain directly into cortical veins (Borden type 3, Cognard type III and IV). A systematic English literature review of SSS vDAVF was made. Systematic literature review revealed a total of 31 published cases. These were commonly seen in male population, (24 males, 77.41%, 24/31). Average age of patients was 54 years. A total of 24 patients (77.41%, 24/31) had aggressive clinical presentations with 13 patients (41.93%, 13/31) having intracranial hemorrhages (ICH). Two patients had rebleeding (15.38%, 2/13). Middle portion of SSS was commonly involved (15 cases, 75%). A total of 25 (96.15%, 25/26) cases had patent SSS. Most of the fistulas were idiopathic (65.38%, 17/26), with trauma being a frequent etiological factor (26.92%, 7/26). Venous ectasia was seen in 19 patients (59.37%, 19/32). Middle meningeal arterial (MMA) supply was seen in all patients (100%, 26/26), with bilateral MMA supply in 21 cases (80.76%), and unilateral in 5 cases (19.23%). Twenty patients (62.50%, 20/32) received only endovascular treatment (EVT), while four patients had EVT followed by surgery (12.5%, 4/32). Transarterial route via MMA was the preferred treatment option (79.16%). Complete obliteration of fistulas was noted in all cases (100%, 30/30). No immediate complication was noted after EVT. As much as 92.30% patients showed good recovery. Thus, SSS vDAVF forms a special subgroup of DAVF, with aggressive presentation, and warrants urgent treatment. EVT is effective treatment option and can produce complete obliteration.
