How is coronary perforation recognized and what are the typical initial treatment options during PCI?

• A. Sudden vessel spasm that responds to nitroglycerin.
• B. Occlusion from a clot treated with antiplatelets.
• C. Dissection without perforation treated with stent.
• D. Extravasation of contrast beyond a vessel with risk of pericardial effusion; treat with balloon tamponade, reversal of anticoagulation if needed, covered stent or coil embolization, and pericardiocentesis.

Answer: (D)

Coronary perforation is identified when contrast leaks outside the coronary vessel into the surrounding space, often visible on angiography as contrast tracking beyond the vessel wall and, if the situation progresses, rapid development of pericardial effusion with or without hemodynamic instability. Initial management focuses on stopping the bleed and preventing tamponade. Start with balloon tamponade by inflating a noncompliant balloon at the perforation site to compress the leak. If anticoagulation was given, reversal (for example, protamine after heparin) helps limit ongoing bleeding. Prepare for definitive sealing of the perforation when feasible: placing a covered stent to seal the breach, or using coil embolization or other methods to occlude the injured vessel if necessary. If signs of tamponade appear or the patient becomes unstable, perform pericardiocentesis to relieve pressure; obtain rapid surgical backup for definitive repair if needed.
