BACKGROUND The most appropriate approach to anatomic pulmonary resection has been debated with the advance of minimally invasive techniques and especially the common use of mechanical staplers. Video assisted surgery and muscle-sparing thoracotomy are established options of surgical approach for lung resection. We utilize a combined technique of vertical(More)
OBJECTIVE We evaluated focused training in coronary artery anastomosis with a porcine heart model and portable task station. METHODS At "Boot Camp," 33 first-year cardiothoracic surgical residents participated in 4-hour coronary anastomosis sessions (6-7 attending surgeons per group of 8-9 residents). At beginning, midpoint, and session end, anastomosis(More)
BACKGROUND High-energy phosphate metabolism is altered in the ischemic myocardium. We investigated the effects of in vivo administration of phosphocreatine (PCr) in a transient ischemic rat model to emulate off-pump myocardial revascularization. STUDY DESIGN Rats received either PCr (100 mg/kg) or saline intravenously 1 hour before surgery. Regional(More)
PURPOSE To report 5-year contrast-enhanced magnetic resonance imaging findings of the REST trial recruits who underwent either uterine artery embolization (UAE) or myomectomy. METHODS A total of 157 patients were randomized to UAE or surgery (hysterectomy or myomectomy). Ninety-nine patients who had UAE and eight patients who had myomectomy were analyzed.(More)
Severe mitral valve regurgitation due to systemic lupus erythematosus is a rare cause of valvular heart disease, necessitating valve surgery. Currently, there are 36 case reports in the world medical literature of mitral valve replacement or repair in patients who have lupus. The current trend in mitral valve surgery is toward anatomic valve repair. In(More)
Thoracotomy is not infrequently performed in patients with suspected pulmonary carcinoma but with no histological or cytological confirmation of malignancy. The intraoperative decision to proceed with major pulmonary resection (lobectomy or pneumonectomy) is difficult if a large or central lesion precludes total excisional biopsy. Incisional or needle(More)
Periodic review of clinical results is essential to ensure that high-quality patient care is maintained. To that end, we reviewed the morbidity and operative mortality in a consecutive series of 369 pulmonary lobectomies performed between January 1, 1970, and December 31, 1983. There were 251 male and 118 female patients with a mean age of 50.6 years. The(More)
Little is known about the strength of suture lines and stapled closures of the bronchus, pulmonary arteries, and pulmonary veins. This experiment tested and compared the hydrostatic leakage point of each of these structures when closed by either sutures or staples. Fourteen fresh mature porcine cadavers and 8 human cadavers of age greater than 50 years were(More)
Bioelectric properties and ion transport of excised human segmental/subsegmental bronchi were measured in specimens from 40 patients. Transepithelial electric potential difference (PD), short-circuit current (Isc), and conductance (G), averaged 5.8 mV (lumen negative), 51 microA X cm-2, and 9 mS X cm-2, respectively. Na+ was absorbed from lumen to(More)
BACKGROUND Obesity is epidemic in the United States and afflicts 97 million adults. Prior single center studies have been contradictory as to obese patients having higher risks with coronary artery bypass operations. Our objective was to assess the independent effect of both moderate (body mass index [BMI], 35 to 39.9) and extreme (BMI > or = 40) obesity on(More)
