Vertical axillary thoracotomy offers the specific advantages of minimum trauma and maximum preservation of chest wall function. A cosmetically acceptable scar results. The vertical axillary thoracotomy is specifically indicated in patients requiring less than the maximum intrathoracic exposure provided by the most traumatic posterolateral or anterolateral thoracotomy. The surgical technique is presented.
Intra-aortic balloon counterpulsation (IABC) provides effective mechanical circulatory assistance (MCA) in many patients with cardiac disease characterized by low cardiac output and/or myocardial ischemia. The intra-aortic balloon pump (IABP) has been used almost exclusively in the care of patients with cardiac disease as their primary medical disorder. This report presents use of the IABP in three cases where cardiac disease was present, but abdominal pathology necessitating urgent surgical intervention was the primary medical concern. Experience with these three cases suggest that operative and early postoperative use of IABC in patients with documented heart disease undergoing major non-cardiac surgical procedures may reduce the high incidence of cardiac complications.

Intra-aortic balloon counterpulsation (IABC) is the form of mechanical circulatory assistance in widest clinical use today. The clinical results with IABC employed in 63 patients over a four-year period are presented. The clinical conditions necessitating mechanical circulatory assistance were: cardiogenic shock following acute myocardial infarction; myocardial infarction complicated by mitral valyular regurgitation or ventricular septal defect; preinfarction angina syndrome; postcardiotomy cardiogenic shock with pump oxygenator dependence; postcardiotomy cardiogenic shock during the postoperative recovery period; and septic shock. Survival and discharge from hospital occurred with 32 of 63 patients (51%). Evaluations of left ventricular function were studied in 20 patients on IABC by construction of Frank Starling curves, with cardiac output determined by thermodilution techniques. In general, IABC shifted the curves to the left and increased their slope.
