Recently, noninvasive imaging modalities such as electron-beam computed tomography, magnetic resonance angiography, and single-slice helical computed tomography (CT) have emerged as ways to visualize the coronary arteries. With regard to internal mammary artery grafts, however, conventional 3D imaging techniques have failed to demonstrate consistently satisfactory performance. We overcame these...

To evaluate the safety and efficacy of a novel, reverse thermo-sensitive polymer (LeGoo™) for its ability to provide temporary coronary occlusion and hemostasis during minimally invasive direct coronary artery bypass (MIDCAB) surgery. Between January 2009 and March 2009, 20 consecutive MIDCAB patients were studied. Ten patients received a conventional MIDCAB procedure using proximal vessel loop...

CONTEXT Left ventricle diastolic dysfunction (LVDD) is gaining importance as useful marker of mortality and morbidity in cardiac surgical patients. Different algorithms have been proposed for the intraoperative grading of DD. Knowledge of the particular grade of DD has clinical implications with the potential to modify therapy, but there is a paucity of literature on the role of diastolic funct...

introduction: esophageal cancer is a common gastro intestinal malignancy. one of the most common techniques of surgery in esophageal cancer is transhiatal esophagectomy with esophagogastric anastomosis in the neck. this technique is accompanied by complications like chronic gastero-esophegeal reflux and late stenosis. this study was designed to compare the risk of complications after two surgic...

abstract   background : although, different studies on end-to-side nerve repair, results are controversial. the importance of this method in case is unavailability of proximal nerve. in this method, donor nerves also remain intact and without injury. in compare to other classic procedures, end-to-side repair is not much time consuming and needs less dissection. overall, the previous studies in ...

Background: : Radiotherapy is an important factor which results in increase of anastomosis leakage. Diverting loop ileostomy has been usually performed after colorectal anastomosis with history of neo-adjuvant radiotherapy to decrease the chance of leakage. Considering this effect, we assessed the feasibility and outcome of human amniotic membrane in rectal anastomosis in dogs previously treate...

introduction drought stress is one of the most yield reduction factor of lima bean where effects on the more than 60% of bean world production. in this regard, solutions that help increase productivity with high water efficiency in this region can change the agricultural crop production. one of the solutions is using organic materials (acid humic). humic acid with linkage of water molecules and...

Background: Radiotherapy is one of the most important factors which results in negative effects on wound healing and increases anastomosis leakage. Diverting loop ileostomy has been usually performed after colorectal anastomosis in cases of colorectal cancer with a history of neoadjuvant radiotherapy to decrease the chance of leakage. Considering the side effects of diverting loop ileostomy, th...
