angioembolization
Pronunciation: AN-jee-oh-em-bol-ih-ZAY-shun
Minimally invasive procedure using catheter-guided coils or particles to stop internal bleeding.
Full Definition
A radiological intervention where a catheter is guided through blood vessels to the site of hemorrhage, and embolic materials (coils, plugs, or particles) are deployed to occlude the bleeding vessel. This technique is particularly valuable in trauma surgery for controlling hemorrhage from solid organs like the liver, spleen, or pelvis when surgical intervention carries high risk. The procedure can be performed while the patient remains hemodynamically stable and often serves as a bridge to definitive surgical repair.
Usage
Usage note: Often abbreviated as TAE (transcatheter arterial embolization) in trauma contexts.
