vessel perforation
Iatrogenic breach of vessel wall integrity during endovascular procedures, classified by severity and hemodynamic impact.
Full Definition
Vessel perforation is a serious procedural complication involving disruption of arterial or venous wall integrity, typically caused by guidewires, catheters, balloons, or other interventional devices. Perforations are classified according to severity, from small wire perforations with minimal contrast extravasation to large ruptures with significant hemorrhage. Management depends on perforation size, location, and hemodynamic consequences, ranging from conservative observation to emergency covered stent placement or surgical intervention. Prevention strategies include careful wire manipulation, appropriate device sizing, and recognition of high-risk anatomy such as severely calcified or tortuous vessels.
Usage
Usage note: Specify anatomical location, severity grade, and immediate management when documenting.

- "Wire manipulation resulted in small vessel perforation that sealed spontaneously without hemodynamic compromise." — Complication report
- "Management of coronary vessel perforation required immediate covered stent deployment to control bleeding." — Emergency procedure documentation
