The goddess Chinnamastā squirting blood. Blood squirt (blood spurt, blood spray, blood gush, or blood jet) is a projectile expulsion of blood when an artery is ruptured. Blood pressure causes the blood to bleed out at a rapid, intermittent rate in a spray or jet, coinciding with the pulse, rather than the slower, but steady flow of venous bleeding.
The common carotid artery is often used in measuring the pulse, [3] especially in patients who are in shock and who lack a detectable pulse in the more peripheral arteries of the body. The pulse is taken by palpating the artery just deep to the anterior border of the sternocleidomastoid muscle at the level of the superior border of the thyroid ...
The underlying mechanism involves inflammation of the small blood vessels that supply the walls of larger arteries. [4] This mainly affects arteries around the head and neck, though some in the chest may also be affected. [4] [8] Diagnosis is suspected based on symptoms, blood tests, and medical imaging, and confirmed by biopsy of the temporal ...
The head and neck are emptied of blood by the subclavian vein and jugular vein. Right side of neck dissection showing the brachiocephalic, right common carotid artery and its branches The brachiocephalic artery or trunk is the first and largest artery that branches to form the right common carotid artery and the right subclavian artery .
The most common treatments are medications and surgery to repair the damaged blood vessels in your brain. Valvular heart disease Heart valve problems may be treated with medications or surgery.
The jugular vein runs parallel to the carotid artery and operates under much lower pressure, returning deoxygenated blood to the heart, whereas the carotid artery, a high-pressure vessel supplying oxygenated blood to the brain, is far more critical and vulnerable in sustaining cerebral circulation.
Particular blood disorders, especially polycythemia vera and paroxysmal nocturnal hemoglobinuria; Use of estrogen-containing forms of hormonal contraception; Meningitis and infections of the ear, nose and throat area such as mastoiditis and sinusitis; Direct injury to the venous sinuses; Medical procedures in the head and neck area
The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization of the internal jugular vein. It can be useful in the differentiation of different forms of heart and lung disease. Classically three upward deflections and two downward deflections have ...
