Right Ventricular Perforation From a Floating Rib Following Deep Sternal Wound Infection Debridement and Application of a Vacuum-Assisted Closure Device: A Case Report and Literature Review.

Introduction: Deep sternal wound infection following major cardiac surgery is a deleterious complication with sequelae that can be life threatening. The use of vacuum-assisted closure therapy in management of sternal wounds with resultant right ventricular rupture has been documented in the cardiothoracic and to a lesser extent in the reconstructive literature. Methods/Case Report: We present a case of a 67-year-old male patient who suffered from right ventricular perforation from a floating rib following debridement of a deep sternal wound infection and placement of a vacuum-assisted closure device. Results: Despite meticulous debridement and ensuring the release of all retrosternal adhesions, massive bleeding was encountered shortly after application of the vacuum-assisted closure device. Fortunately, quick identification of the complication and the application of direct manual pressure allowed for swift return to the operating room for repair of the defect. The patient secondarily underwent definitive closure of the mediastinal wound with an omental flap and bilateral pectoral advancement flaps. Discussion: Following the conclusion of this article, the reconstructive surgeon should be able to (1) identify patients at risk for ventricular perforation, (2) exhaust all means intraoperatively to prevent cardiac perforation when using vacuum-assisted closure therapy, (3) comprehend the physiology associated with vacuum-assisted closure use in this patient population, (4) have protocols in place for the management of patients with deep sternal wound infection with vacuum-assisted closure therapy postoperatively, and (5) understand basic tenets of ventricular rupture treatment should this occur to ensure prompt repair and survival.
