Two Decades Using Stentless Porcine Aortic Root in Right Ventricular Outflow Tract Reconstruction.

Background: The stentless porcine aortic root prosthesis (SPAR) has been described as a suitable valve for right ventricular outflow tract reconstruction (RVOTR). Indiana University Methodist Hospital in Indianapolis, Indiana began using this valve for RVOTR in 1998. This study reports medium-term to late- term outcomes of the valve in the pulmonary position.

Timing and perioperative risk factors for in-hospital and post-discharge venous thromboembolism after colorectal cancer resection.

Introduction: We postulated that the risk of venous thromboembolic disease (VTE) may persist after discharge and tested this hypothesis in patients undergoing colorectal resection for cancer.

Methods: The American College of Surgeons National Surgery Quality Improvement Program database was queried for patients undergoing colorectal resections for cancer from 2005 to 2009. The outcome analyzed was a 30-day deep vein thrombosis (DVT) and/or pulmonary embolism (PE).
