acquaintance with the different anatomical variations of the arterial supply of the gallbladder is of great importance in hepatobiliary surgical procedures. a rare variation of the hepatobiliary arterial system was found during anatomical dissection of a female iranian cadaver. two cystic arteries were present, the first arising directly from the right hepatic artery and the second from the gas...

Background: To evaluate the present status of blood utilization and develop practice guidelines in teaching hospitals in Northern Iran. Methods: We retrospectively analyzed the amount of blood prepared and used preoperatively for 11 elective procedures, from March 2010 to March 2011 in teaching hospitals in Northern Iran. Study variables included the crossmatch transfusion ratio, the transfusi...

In 44 consecutive patients undergoing elective open heart surgery (OHS), serial electrocardiograms (ECG), vectorcardiograms (VCG), serum CPK, cardiac isoenzymes (CPKMB), and myocardial images using Tc-99m pyrophosphate were obtained, before and after the operation, for the detection of acute myocardial infarction (AMI). Twenty-nine patients developed one or more positive tests postoperatively. ...

Rib grafts in facial plastic surgery are becoming more frequently used. Small animal models, although not ideal may be used to emulate costal cartilage-based procedures. A surgical characterization of this tissue will assist future research in the selection of appropriate costal segments, based on quantitative and qualitative properties. The objective of this study is to assess the surgical ana...
