introduction: extreme altitude travel has gained popularity globally for adventurous, scientific, and military endeavors. cerebral venous sinus thrombosis (cvst) at extreme altitude is a rare, covert, and emergent condition requiring immediate intervention. case presentation: a case of cvst masqueraded as high altitude cerebral edema (hace) at 6700 m/22000 ft in karakoram himalayas. atypical ol...

background: sildenafil is a selective inhibitor of phosphodiesterase type 5 (pde5) which currently used for the treatment of erection dysfunction (ed). medicine approved by the fda for treatment of pulmonary hypertension. although there is no evidence of hypercoagulation states being associated with the use of pde5 inhibitors, several animal studies suggest that pde5 inhibitors may cause arteri...

Hyperhomocysteinemia can cause cerebral venous thrombosis. Recombinant tissue plasminogen activator is one of the treatment options for cerebral venous thrombosis in selected cases. We present here a 7-year-old boy with homocysteinuria with stroke. MRI of brain showed cerebral venous sinus thrombosis. We successfully treated with intravenous recombinant tissue plasminogen activator. He recovere...

Cerebral venous sinus thrombosis (CVST) is a severe and rare pregnancy complication. The most common symptom headache. However, it less for headaches to be accompanied by seizures. Postpartum eclampsia (PPE) traditionally refers convulsions within seven days, but can occur up 4 weeks after birth. In this case report, we present our patient who developed cerebral thrombosis, which very complicat...

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...

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...

BACKGROUND The purpose of this study is to demonstrate the advantages of gradient echo (GRE) sequences in the detection and characterization of cerebral venous sinus thrombosis compared to conventional magnetic resonance sequences. METHODS A total of 17 patients with cerebral venous thrombosis (CVT) were evaluated using different magnetic resonance imaging (MRI) sequences. The MRI sequences i...

c erebral venous sinus thrombosis is an uncommon condition, which over the past 10 years has been diagnosed more frequently due to greater awareness and the availability of better non-invasive diagnostic techniques. Because of the generally good prognosis and variable clinical signs, many cases remain clinically undetected but some patients suffer complications and die. CVST is slightly more co...

From time immemorial, cerebral thrombosis used to be synonymous with arterial thrombosis. But, cerebral venous thrombosis was not uncommon but neurologists and pathologists were not properly oriented regarding cerebral venous thrombosis(CVT) specially because the anatomical knowledge were not updated and nobody actually believed that thrombosis can occur in low velocity capacitance vessels as o...

Cerebral venous thrombosis is a rare serious neurological disorder that may cause vital or morbid consequences if not diagnosed and treated promptly. It is a unique cerebrovascular disorder that predominantly affects adults in their third and fourth decades. The incidence of CVST in adults is estimated to be 4 cases per million of the population, and 7 cases per million in children. In the last...
