Randomized Controlled Trial Multicenter Study
Evaluation of the topical hemostatic efficacy and safety of TISSEEL VH S/D fibrin sealant compared with currently licensed TISSEEL VH in patients undergoing cardiac surgery: a phase 3, randomized, double-blind clinical study.
TISSEEL VH is the only commercially available fibrin sealant indicated as an adjunct to conventional methods of hemostasis during cardiac surgery. A next generation fibrin sealant (TISSEEL VH S/D) has been developed in frozen, ready-to-use form with an added virus inactivation step (solvent/detergent [S/D] treatment) to provide added safety and convenience to the currently licensed product. This study was performed to compare efficacy and safety of the two products. ⋯ TISSEEL VH S/D is safe and effective for use as an adjunct to hemostasis in patients undergoing cardiac surgery.

The aim of the study was to demonstrate the utility of endovascular stent-graft repair for emergency management of aorto-iliac surgery complications. Between 1997 and 2004, in our institute, 201 patients underwent transluminal endovascular graft placement. In 3 patients (1.4%), previously submitted to conventional aortic surgery, endovascular treatment was carried out due to the occurrence of late complications: 1 secondary aortocaval fistula, 1 impending rupture of aortic pseudoaneurysm and 1 secondary aorto-enteric fistula. ⋯ The 3(rd) patient, with secondary aorto-enteric fistula, was submitted 2 months later to aortic graft removal and axillo-bifemoral bypass because of infection development. For the treatment of abdominal aortic surgery complications in high risk patients, particularly in emergency situations, endovascular approach is a feasible and safe alternative to conventional open repair. Further evaluation of this technique and longer follow-up will determine its exact role in the management of these life-threatening complications.

Considerable controversy surrounds mortality from non-neoplastic diseases during the postoperative follow-up of patients with non-small cell lung cancer (NSCLC) and chronic obstructive pulmonary disease (COPD). This study investigated the incidence of mortality from cardiovascular and respiratory (CVR) causes in patients with COPD submitted to follow-up after lung resection for NSCLC, and identified preoperative and postoperative risk factors. ⋯ The findings suggest that postoperative CVR death may be expected in patients with COPD and advanced stage NSCLC or in those undergoing completion pneumonectomy or partial resection of the other lung for a second primary tumor. Other risk factors are previous coronary artery disease and/or heart failure, exertional dyspnea and predicted postoperative FEV1 <1000 mL.

Morbidity and mortality after surgical interventions are influenced by different preoperative factors. We investigated the impact of body mass index (BMI) on outcome after coronary artery bypass grafting (CABG). ⋯ The results suggest that low BMI is associated with increased morbidity and mortality after CABG. Overweight is associated with more postoperative complications and longer hospitalisation but not with an increased early or long-term mortality.

Aortic valve replacement (AVR) after previous coronary artery bypass grafting (CABG), particularly in a patent left internal thoracic artery (ITA), is a challenge. Avoidance of injuring the patent graft and ensuring myocardial protection are important issues in the management of these patients. The aim of this study was to evaluate a simplified surgical approach to these reoperations. ⋯ We believe that the indication for AVR in patients scheduled for CABG should be re-evaluated. In those in which Redo-surgery for new or increased valve stenosis is indicated, a simple and safe surgical option is presented.
