“…Secondary effects including intracerebral hemorrhage or cerebral edema, particularly not representative of an arterial territory could suggest a cerebral venous sinus thrombosis. A triangular hyperdensity noted in the posterior third of the sagittal sinus or proximal transverse sinus known as the “delta sign,” represents a thrombosis in this area (2,9,55). A CTV with 3-D reconstructions, if preferred, may be helpful in revealing a thrombus in a major draining vein (6).…”

Dural venous sinus thrombosis (DVST) is a rare cause of stroke, which typically affects young women. The importance of identifying pre-disposing factors that lead to venous stasis lies in the foundation of understanding the etiology, pathophysiology and clinical presentation. The precise therapeutic role of interventional therapies is not fully understood though the current data do suggest potential applications. The aim of the study was to perform a systematic review and meta-analysis to evaluate the utility of and short-term 30-day survival after endovascular therapy for patients with DVST. Standard PRISMA guidelines were followed. Data sources included PubMed keywords and phrases, which were also incorporated into a MeSH search to yield articles indexed in Medline over a 5-year period. All RCTs, observational cohort studies, and administrative registries comparing or reporting DVST were included. Sixty-six studies met inclusion criteria. 35 articles investigating treatment in a summation of 10,285 patients were eligible for data extraction and included in the review of treatment modalities. A total of 312 patients were included for statistical analysis. All patients included received endovascular intervention with direct thrombolysis, mechanical thrombectomy or both. 133 (42.6%) patients were documented to have a neurologic decline, which prompted endovascular intervention. All patients who had endovascular interventions were those who were started on and failed systemic anticoagulation. 44 patients were reported to have intracranial hemorrhages after intervention. Regardless of systemic anticoagulation, patients were still reported to have complications of VTE and PE. Primary outcome at 3-6 month follow up revealed mRS<1 in 224 patients. DVST presents with many diagnostic and therapeutic challenges. The utility of invasive interventions such as local thrombolysis and mechanical thrombectomy is not fully understood. It is exceedingly difficult to conduct large randomized trials for this low incidence disease process with large pathophysiological heterogeneity.

Cerebral venous thrombosis is a rare condition which constitutes 0.5% to 2% of all types of stroke and carries a mortality of up to 20% to 50%. It leads to cerebral edema, infarction, hemorrhage and venous hypertension. Clinically the diagnosis is confirmed using enhanced computed tomography (CT) angiography which demonstrates an empty delta sign in cerebral veins, particularly in the superior sagittal sinus. However, postmortem CT (PMCT) findings on cerebral venous thrombosis have not been documented in the literature. We present a case report of a 69-year-old man who on unenhanced PMCT scan showed an empty delta sign in the cerebral veins. The empty delta sign was able to be demonstrated in unenhanced PMCT which can be explained by hyper attenuation of the dural veins at postmortem forming an internal contrast highlighting the thrombus.
