Sinovac is an inactivated virus COVID 19 vaccine given emergency authorization for Pandemic. Different adverse reactions have been seen in after marketing of vaccines. Here we present a case patient who developed cerebral venous sinus thrombosis two weeks the first dose SINOVAC vaccine.

The location of the original sites of the lesions was studied in 22 non-traumatic and 21 traumatic intracavernous carotid aneurysms in which the neck of the aneurysm was confirmed, and also in 23 traumatic carotid-cavernous fistulas in which the location of the fistula was identified. In the cavernous sinus, common sites of non-traumatic and traumatic carotid aneurysms as well as traumatic caro...

BACKGROUND AND PURPOSE Transverse sinus stenosis is common in patients with IIH. While the role of transverse sinus stenosis in IIH pathogenesis remains controversial, modeling studies suggest that stent placement within a transverse sinus stenosis with a significant pressure gradient should decrease cerebral venous pressure, improve CSF resorption in the venous system, and thereby reduce intra...

BACKGROUND AND PURPOSE A positive correlation between HCT and CT attenuation of intravascular blood has long been assumed but has never been established by using substantial patient numbers and modern CT equipment. The purpose of this study was to determine whether apparent increased attenuation on CT in cerebral venous sinuses can be attributed to hemoconcentration alone and to assess whether ...

Cerebral venous sinus thrombosis is a challenging condition because of its variability of clinical symptoms and signs. It is very often unrecognised at initial presentation. All age groups can be affected. Large sinuses such as the superior sagittal sinus are most frequently involved. Extensive collateral circulation within the cerebral venous system allows for a significant degree of compensat...

A 44 year old male patient, non smoker, hypertensive was admitted with loss of consciousness followed by transient weakness of the right side of the body. He gave a past history of recurrent TIAs. On admission, he was fully conscious and oriented. Pulse 60/mt, BP 120/80 mm Hg. There were no cutaneous telangiectasias. There was no carotid bruit. CVS S1 S2 heard normally. Central nervous system e...

We evaluated the ability of dynamic CT scanning to accurately demonstrate the laterosellar extradural venous spaces. Careful examination of 680 consecutive patients with this technique has permitted us to describe four main venous groups: the veins of the lateral wall (present in 98% of cases), the vein of the inferolateral group located beneath cranial nerve VI (present in 92% of cases), the m...

OBJECTIVE Deep venous stenting has become the primary treatment option for chronic venous obstructive disease, both for iliac vein compression and post-thrombotic venous lesions. Until recently, only stents aimed at arterial pathology were used, because no dedicated venous stents were available. However, three such stents have now become available. These venous stents are characterized by incre...

BACKGROUND AND PURPOSE Thrombosis of the cerebral venous sinus may cause venous congestion, cerebral edema, and infarction. The role of cerebrovenous disorders in arterial ischemic stroke is unknown. The objective of this study was to examine the contribution of ipsilateral cranial venous abnormalities to the development of cerebral edema in middle cerebral artery infarction. METHODS This is ...

BACKGROUND A comprehensive assessment of various vascular anomalies and variants associated with venous pulsatile tinnitus (PT) by radiography is essential for therapeutic planning and improving the clinical outcome. This study evaluated the incidence of various vascular anomalies and variants on the PT side and determined whether these lesions occurred as multiple or single entities. METHODS...
