Research paper thumbnail of An Algorithm for Abdominal Wall Reconstruction

The correction of complex defects is a challenge to both plastic and reconstructive and general surgeons. The anatomy of the abdominal wall, as well as considerations in patient assessment and surgical planning, are discussed. A simple classification of abdominal wall defects based on size, depth, and location is provided. Publications regarding the various abdominal reconstruction techniques are reviewed and summarized to familiarize the reader with the treatment options for each particular defect. Finally, an algorithm is presented to guide the surgeon in selecting the optimal reconstructive technique.

From 1981 to 1991, 118 consecutive patients with ejection fraction less than or equal to 0.25 underwent isolated coronary artery bypass grafting at Duke University Medical Center. Operative mortality was 11%. Ventricular arrhythmia requiring treatment was the most common postoperative complication (27%), followed by low cardiac output state (22%). Median length of postoperative hospitalization was 9 days. Kaplan-Meier estimate of survival at 1 year and 5 years was 77.2% and 57.5%, and was better than estimated survival with medical therapy alone. Survivors experienced significant improvement in angina class (p < 0.0001), congestive failure class (p < 0.0001), and follow-up ejection fraction (p < 0.005). Of 22 preoperative factors evaluated by univariate survival analysis, five were associated with significantly greater mortality: other vascular disease (p < 0.005), female sex (p < 0.005), hypertension (p < 0.005), elevated left ventricular end-diastolic pressure (p < 0.05), and depressed cardiac index (p < 0.05). Considering length of hospitalization, three factors showed significant adverse effect in a multivariate Cox model: time on cardiopulmonary bypass (p < 0.005), acute presentation (p < 0.005), and female sex (p < 0.01). These data and review of the literature suggest that patients with coronary artery disease and severely depressed ejection fraction benefit from coronary artery bypass grafting, and specific preoperative factors may help determine optimal treatment.

This technique was used in 9 patients and allowed minimal dissection, reducing the risks of hemorrhage and injury to previously placed patent grafts. Cardiopulmonary bypass was used in 4 patients in whom myocardial protection was accomplished with systemic hypothermia. Right atrial cannulation provided adequate venous return, with arterial inflow established via the femoral artery (n = 2) or edo coronary artery bypass grafting is becoming com-

Research paper thumbnail of Neovascularization after transmyocardial laser revascularization in a model of chronic ischemia

Annals of Thoracic Surgery, 1998

Background. The mechanism of clinical improvement after transmyocardial laser revascularization (... more Background. The mechanism of clinical improvement after transmyocardial laser revascularization (TMR) is unknown. One hypothesis holds that TMR causes increased myocardial perfusion through neovascularization. This study sought to determine whether angiogenesis occurs after TMR in a porcine model of chronic myocardial ischemia.
