Additional arterial grafts such as the right internal mammary artery (RIMA) or the radial artery (RA) have been proposed to improve long term outcomes in coronary artery bypass grafting (CABG). RA is largely preferred over RIMA as it is less technically demanding and there is a perception that bilateral IMA usage increases the risk of sternal wound complications. However, there is a paucity of direct comparison of the two conduits to guide surgeons to choose the best second arterial conduit for CABG. ⋯ RIMA as a second conduit did not increase the operative risk including sternal wound complications and improved long term outcomes including overall survival when compared to RA. This advantage was stronger among diabetic and obese patients. These findings strongly support RIMA as the first choice second arterial conduit in CABG. Further randomized studies with angiographic control and long-term follow-up are needed to address this issue.

Although various surgical procedures have been described for pilonidal sinus disease, the best surgical technique is still controversial. Aim of this study was to compare the short term results of modified limberg flap (MLF) and modified elliptical rotation flap (MERF) for pilonidal sinus disease in terms of postoperative complications, recurrence and patient satisfaction. ⋯ Modified limberg flap reconstruction is still one of the most commonly performed procedures for pilonidal sinus disease because of its low complication and recurrence rate and higher postoperative quality of life. This study shows that modified elliptical rotation flap technique is at least effective as modified limberg flap reconstruction. Further prospective clinical trials are needed to show the effectiveness of this technique on long term.
