Hepatic Artery Occlusion

Possible causes of a liver arterial occlusion include thrombosis (z. B. at hypercoagulability, severe atherosclerosis or vasculitis), emboli (z. B. in endocarditis, tumors, therapeutic embolization or chemoembolization), iatrogenic events (z. B. accidental intraoperative ligature), vasculitis (about nichtthrombotische mechanisms), structural defects of the vessel (z. B. neurysma the hepatic artery), eclampsia, cocaine and sickle cell crisis.

(See also overview of vascular diseases of the liver.) Possible causes of a liver arterial occlusion include thrombosis (z. B. at hypercoagulability, severe atherosclerosis or vasculitis), emboli (z. B. in endocarditis, tumors, therapeutic embolization or chemoembolization), iatrogenic events (z. B. accidental intraoperative ligature), vasculitis (about nichtthrombotische mechanisms), structural defects of the vessel (z. B. neurysma the hepatic artery), eclampsia, cocaine and sickle cell crisis. Typically, this results in a hepatic infarction. In patients with a pre-existing liver oil Plant or portal vein thrombosis, the thrombosis of the hepatic artery leads to ischemic hepatitis. Due to the dual blood supply to the liver this is partially protected from ischemic hepatitis and heart attacks. A closure of the hepatic artery is usually asymptomatic until it comes to a liver infarction or ischemic hepatitis. A liver infarction may be asymptomatic or cause pain in the right upper abdomen, fever, nausea, vomiting and jaundice. Leukocytosis and high transaminases are common. Diagnostic imaging Vascular Diagnosis of liver artery occlusion is confirmed by imaging with ultrasound Doppler sonography, usually followed by angiography. The choice between CT angiography, magnetic resonance angiography and selective angiography depends largely on the availability and expertise. In CT in liver parenchyma, a wedge-shaped area with a slight signal degradation may be recognizable. Causal therapy aligned Treatment depends on the particular cause.
