Most of the venous problems in MS patients have been reported to be truncular venous malformations, including azygous stenosis, defective jugular valves and jugular vein aneurysms. Problems with the innominate vein and superior vena cava have also been reported to contribute to CCSVI. [27] A vascular component in MS had been cited previously ...
Vascular causes of pulsatile tinnitus include venous causes (e.g., high riding or dehiscent jugular bulb, sigmoid sinus diverticulum), arterial causes (e.g., cervical atherosclerosis, potentially life-threatening conditions such as carotid artery aneurysm [56] or carotid artery dissection), or dural arteriovenous fistula or arteriovenous ...
It usually drains into either the sigmoid sinus, or the jugular bulb. It communicates with the basilar venous plexus anteriorly, and the occipital sinus posteriorly (the posterior union of the left and the right marginal sinus usually representing the commencement of the occipital sinus [ 2 ] ); it may form extracranial communications with the ...
The internal jugular vein is a paired jugular vein that collects blood from the brain and the superficial parts of the face and neck. This vein runs in the carotid sheath with the common carotid artery and vagus nerve. It begins in the posterior compartment of the jugular foramen, at the base of the skull.
This is treated with surgery to embolise of the fistula. [1] It may also be affected by a thrombus. [1] This can be treated with anticoagulants. [1] It may be injured by a variety of major trauma. [3] It may also be damaged during surgery, such as that to remove a meningioma. [3] The confluence of sinuses can be imaged with radiology. [1]
External Manual Carotid Compression is Effective in Patients with Cavernous Sinus Dural Arteriovenous Fistulaetreatment. The patients were instructed to compress the carotid artery and jugular vein with the contralateral hand for ten seconds several times each hour (about 6 to 15 times per day).
The cranial nerves of the jugular foramen may be compressed, resulting swallowing difficulty, or ipsilateral weakness of the upper trapezius and sternocleiodomastoid muscles (from compression of the spinal accessory nerve). These patients present with a reddish bulge behind an intact ear drum. This condition is also known as the "Red drum".
Venous hum is a benign auscultatory phenomenon caused by the normal flow of blood through the jugular veins. [1] At rest, 20% of cardiac output flows to the brain via the internal carotid and vertebral arteries; this drains via the internal jugular veins.
