Öğe The arterial distribution and size of greater omentum(1996) Govsa F.; Aktan Z.A.; Arisoy Y.; Aktas E.O.; Ozgur T.The greater omentum (omentum gastrocolica) is a filmy apron draped over the transverse colon and coils of the small intestine. Clinical importance of the omentum have increased in recent years as it is a unique structure being highly vascular. Intact omentum has been used for a variety of clinical reasons which included attempts to increase blood flow to the ischemic heart, brain and legs; to prevent or repair vesicovaginal fistulas; to protect at operation previously irradiated pelvic organs at operation; to treat lymphedema and hydrocephalus; to repair radionecrosis of the chest wall or flexion creases for reconstruction of the breast and to protect a previously irradiated carotid artery after radical neck dissection. The arterial structure of omentum influences the manner in which the omentum can be a lengthened. Also, it is important to know the omental limits before laparotomy. The main aim of this research was to determine the range of lenght and width of omentum and then to correlate them with the height of the the person present. Thus one is able to predict the size and limits of omentum laparotomy. In this study, involving a series of 107 cases, the size of omentum was determined and the types of vascularity were assessed. Correlations between height and omental width, patients' height and omental length were calculated.Öğe The identification of the cystic artery(1997) Aktan Z.A.; Govsa F.; Arisoy Y.; Senyilmaz Y.; Ozgur T.The gallbladder is supplied by the cystic artery. There are several alternative patterns, however, of great interest to the surgeon, including an cystic artery arising from the arteria hepatica propria and passing anterior to the common hepatic artery. A study of the arterial supply of the gallbladder in 75 autopsies and in 50 cadavers is presented. The arteries were visualized and the relations of the cystic artery were found comparable with previous studies.Öğe Variations in the union of the ductus cysticus with the ductus hepaticus communis(1996) Govsa F.; Aktan Z.A.; Varol T.; Uckan H.; Arisoy Y.; Senyilmaz Y.Cholecystectomy is one of the most commonly performed abdominal operations in general surgery. A knowledge of the variable anatomy of the extrahepatic biliary tree is important for the general surgeon, because failure to recognize anatomic variations may result in a significant ductal injury. In this research, the ductus cysticus and types of union of the ductus cysticus with the ductus hepaticus communis were studied in 150 human livers. We observed different forms of the union of these ductus. Angular union was demonstrated in 66 specimens, parallel union was demonstrated in 60 specimens, ductus hepaticus accessorious in 8 specimens and subvesicular duct in 2 specimens. High fusion of the ductus hepaticus dexter and sinister with the ductus cysticus was evident in 8 specimens. In 6 specimens ductus cysticus entered the ductus hepaticus dextra. Abnormal patterns of the ductus cysticus may occur with sufficient frequency to be of importance during cholecystectomy. Based on this findings, it was concluded that knowledge of anatomic variations may enhance success during surgery.
