flush occlusion
Complete arterial blockage extending to the vessel origin without visible stump for catheter engagement.
Full Definition
Flush occlusion describes a complete arterial blockage that extends proximally to the vessel origin or major branch point, leaving no visible arterial stump or entry point for catheter advancement. This finding presents significant technical challenges for endovascular intervention, as there is no angiographically visible target for guidewire or catheter engagement. Flush occlusions are commonly encountered at vessel origins such as the celiac axis, superior mesenteric artery, or major branch vessels. The term is critical in procedural planning as it indicates the need for alternative revascularization approaches or specialized recanalization techniques.
Usage
Usage note: Emphasize implications for procedural planning and intervention approach.
