INTRODUCTION Seizure involves less than 1% of pregnancies; however it is associated with increased maternal and fetal complications. Cerebral venous sinus thrombosis is a rare, but potentially life-threatening cause of seizure during pregnancy, presenting primarily as seizure in 12% - 31.9% of cases. Pregnancy and puerperium are known as the risk factors of cerebral venous sinus thrombosis. C...

BACKGROUND Cerebral venous-sinus thrombosis is an uncommon form but important cause of stroke, especially in young-aged women. METHODS We performed a retrospective descriptive-analytical study in which 124 patients with cerebral venous-sinus thrombosis, who referred to Nemazee Hospital, Shiraz University of Medical Sciences from January 2000 to March 2008, were included, and their demographic...

BACKGROUND The high pressures documented in the intracranial venous sinuses in idiopathic intracranial hypertension (IIH) could be the result of focal stenotic lesions in the lateral sinuses obstructing cranial venous outflow. OBJECTIVE To explore the relation between venous sinus disease and IIH. METHODS 12 patients with refractory IIH had dilatation and stenting of the venous sinuses afte...

Cerebral venous thrombosis is a potentially lethal disease. Early diagnosis is essential to improve its prognosis. However, its early diagnosis based on conventional imaging modalities remains a challenge in clinical settings. The purpose of this study was to evaluate whether bright sinus appearance on arterial spin-labeling perfusion-weighted image (ASL-PWI) could help identify cerebral venous...

The association of spontaneous intracranial hypotension with cerebral venous sinus thrombosis is rare. We report here a case of extensive cerebral venous sinus thrombosis involving three sinuses following spontaneous intracranial hypotension. The patient presented no other thrombotic risk factors except for spontaneous intracranial hypotension. This case adds to the evidence that spontaneous in...

BACKGROUND Cerebral dural sinus thrombosis is a rare clinical entity. Symptoms may be vague, and left untreated thrombus progression may be fatal because of venous congestion and infarction. METHODS We report a case of post-traumatic dural sinus thrombosis treated with selective transfemoral, transvenous catheterization and infusion of urokinase. RESULTS Urokinase infusion into the dural ve...

-----------------------------------.... Retrograde coronary sinus perfusion may provide equal if not better myocardial protection than antegrade cardioplegia during certain heart surgeries. The coronary venous system can be divided into the greater and lesser systems and veno-venous and arterio-venous anastomoses. Venous drainage varies greatly and retrograde coronary sinus perfusion depends on...

Background: Food-born botulism is caused by ingestion of contaminated food with clostridium botulinum neurotoxin. Case: In food-born botulism, due to acetylcholine release blockade, neuromuscular signs and symptoms are common, but in this case report we present a food-born botulism with papiledema and venous sinus thrombosis. Conclusion: Papiledema and fever could not rule out the diagnosis...

RATIONALE Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH) is characterized by a pattern of extravasated blood restricted to the perimesencephalic cisterns, normal angiographic findings, and an excellent prognosis with an uneventful course and low risks of complication. The precise etiology of bleeding in patients with PNSAH has not yet been established. The most common hypothesi...
