Comparative Study Clinical Trial
Continuous intravenous insulin infusion reduces the incidence of deep sternal wound infection in diabetic patients after cardiac surgical procedures.
Diabetes mellitus is a risk factor for deep sternal wound infection after open heart surgical procedures. We previously showed that elevated postoperative blood glucose levels are a predictor of deep sternal wound infection in diabetic patients. Therefore, we hypothesized that aggressive intravenous pharmacologic control of postoperative blood glucose levels would reduce the incidence of deep sternal wound infection. ⋯ Use of perioperative continuous intravenous insulin infusion in diabetic patients undergoing open heart surgical procedures significantly reduces major infectious morbidity and its associated socioeconomic costs.

The incidence of mediastinitis after cardiac surgical intervention is reported to be between 0.15% and 5% and is a major cause of postoperative morbidity. A number of risk factors have been identified, most of which are not modifiable. It is our contention that this complication can be reduced to a minimum by the consistent application of good operative technique and postoperative management. ⋯ In a large patient series we found a low incidence of mediastinitis (0.25%) and an even lower incidence of required reoperation (0.19%). Except for the use of bone wax and the use of bilateral mammary arteries in diabetic patients, none of the previously identified risk factors are modifiable. We believe that with strict adherence to perioperative aseptic technique, attention to hemostasis, and precise sternal closure, a very low incidence of mediastinitis can be achieved.

Tumor debulking can greatly improve quality of life for patients with malignant carcinoid syndrome, but hepatic cytoreduction is confounded by carcinoid heart disease, which can cause postsinusoidal portal hypertension, thereby increasing the risk of death from hemorrhage during hepatic resection. We describe a patient with metastatic carcinoid syndrome and carcinoid heart disease who had repair of his carcinoid heart disease and, after improvement of right-sided heart function, had successful hepatic debulking of carcinoid metastases.

Review Comparative Study
Pericardial effusion: subxiphoid pericardiostomy versus percutaneous catheter drainage.
Optimal management of cardiac tamponade resulting from pericardial effusion remains controversial. ⋯ Benign and malignant pericardial tamponade can be safely and effectively managed with subxiphoid pericardiostomy. Percutaneous catheter drainage should be reserved for patients with hemodynamic instability.

A 34-year-old man had development of an aortobronchial fistula 17 years after patch aortoplasty for correction of aortic coarctation and 5 years after blunt chest trauma, an unusual combination of predisposing factors. The clinical presentation, characterized by dysphonia and recurrent hemoptysis, and the surgical findings suggested the posttraumatic origin of the fistula, which was successfully managed by aortic resection and graft interposition under simple aortic cross-clamping, associated with partial pulmonary lobectomy. When hemoptysis occurs in a patient with a history of an aortic thoracic procedure, the presence of an aortobronchial fistula should be suspected. Early diagnosis offers the only possibility of recovery through a lifesaving surgical procedure.
