Abstract:
Coronary perforation is a rare but potentially lethal complication of percutaneous coronary intervention. Management of coronary perforations is mainly conditioned by the extension of coronary rupture and location of the perforation. Successful treatment is highly affected by the operator's familiarity with tools and dedicated techniques to achieve prompt sealing of the disruption. We report a case of an epicardial collateral channel perforation occurred during a retrograde chronic total occlusion revascularization procedure that was promptly managed with bilateral coils embolization in the target and in the donor vessel. Based on medical literature an overview of the most helpful techniques to treat these complications is provided.

Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...
