Management of Septal Branch Perforation and Septal Hematoma During Retrograde Treatment of Coronary Chronic Total Occlusion Using Fat Embolization.

Septal vessel perforation followed by septal hematoma is a rare complication of retrograde approach for treatment of coronary chronic total occlusions, possibly leading to septal rupture. We report 2 cases of patients with septal vessel perforation and subsequent hematoma successfully treated with autologous fat embolization. Such technique is inexpensive, omnipresent, and relatively easy to perform.
