Intraluminal shunt placement and off-pump coronary revascularization for coronary artery stab wound

How to mend a broken heart: a major stab wound of the left ventricle

A 28-year-old male admitted with a stab wound under his left nipple, underwent emergency surgery because of confusion, a decreasing blood pressure and increasing tachycardia. A median sternotomy incision was made and after establishing cardiopulmonary bypass, a 7 cm wound in the left ventricle and a smaller wound in the left atrium were repaired. An injured segment of lung was resected and the left anterior descending and circumflex arteries were grafted after weaning from cardiopulmonary bypass was initially unsuccessful. Although the patient suffered a stroke, probably due to prehospital hypoperfusion, he eventually recovered without major sequelae. In addition to the case report we present a literature review of the last 15 years pertaining the management of penetrating cardiac injury.

Management of Traumatic Coronary Artery Injuries: Advantages of Off-Pump Coronary Artery Bypass

Coronary artery injuries are rare but highly lethal. Debate exists as to the best treatment for this complex set of injuries, with historical treatment favoring arterial ligation. Although conventional coronary artery bypass grafting using cardiopulmonary bypass has been used somewhat successfully, enthusiasm for off-pump CABG (OPCAB) has grown more recently. We report two unique cases of left anterior descending coronary arterial injuries managed successfully with OPCAB.

Off-Pump Coronary Artery Bypass is an Alternative to Conventional Cardiopulmonary Bypass When Repair of Traumatic Coronary Artery Injuries is Indicated

Coronary artery injuries after penetrating cardiac trauma are rare. The standard approach to these injuries has traditionally been coronary artery ligation. When cardiac perfusion is profoundly compromised, cardiopulmonary bypass has been used to facilitate revascularization, although with serious morbidity. We report a case of traumatic left anterior descending coronary artery transection repaired off-pump in a young stabbing victim. Penetrating traumatic cardiac injuries are highly lethal injuries. Cardiopulmonary bypass has been used for myocardial revascularization when cardiac perfusion is compromised, although with significant complications. Off-pump coronary artery bypass is a safe alternative in the traumatized patient.

Damage control surgery for thoracic injuries

Damage control of thoracic injuries begins frequently with an emergency department thoracotomy via an anterolateral incision. Bleeding and air leaks are quickly temporised. As opposed to abdominal damage control where most injuries can be temporised, most thoracic injuries require initial definitive repair. Thus, the goal of thoracic damage control is to perform the least definitive repair using the fastest and easiest techniques to shorten the operative time as much as possible. There are some injuries that can be temporised and require re-operation once physiologic normality has been achieved.

Off-pump cardiac revascularization after a complex stab wound

Penetrating cardiac injuries are among the most dramatic and lethal of all injuries. High survival rates in selected reports have given the erroneous impression that the lethality of cardiac injuries has diminished in recent years. In a review of 1,198 cases of penetrating cardiac trauma from South Africa, only 6% of patients arrived at hospital alive. Many patients with proximal coronary artery injuries present without signs of life. Cardiopulmonary bypass is advocated as a means of salvage, but mortality rates are high. We present a case of arterial revascularization using off-pump technology.
