intraluminal thrombus

Full Definition

Intraluminal thrombus refers to blood clot formation within the lumen or interior cavity of a blood vessel. This can occur due to various factors including altered blood flow patterns, endothelial injury, or hypercoagulable states. In vascular surgery, intraluminal thrombus is particularly relevant in aneurysm management, where it can affect sizing for endovascular repair, and in acute arterial occlusion where it may indicate the need for emergent thrombectomy.

Usage

Usage note: Distinguish from mural thrombus, which forms along vessel walls rather than within the lumen.
