In the present study, we investigated the origin and course of the gonadal arteries and clinical implications of variant gonadal arteries are discussed.

In the remaining 5 cases, gonadal artery of renal origin was present in 3 cases, two on right and one on left side and of middle suprarenal origin was present in 2 cases on the left side. The present study agreed with the text book account i.e. right testicular artery passing anterior to inferior vena cava in majority of the cases i.e. 27 (90%). In the remaining 3 cases (10%), the right testicular artery was posterior to inferior vena cava. In our study, out of a total of 60 dissections, 57 dissections confirmed to type I pattern (95%). In 2 cases (3.3%) (11 M, 16 M) a type II pattern was seen on the right side. In 1 case (1.7%) (20 M), the left testicular artery arose directly from the aorta and arched over the renal vein giving a type III pattern.

In the 20th century they were perhaps too frequently performed whereas the 21st century has witnessed a steep decline in hysterectomy numbers. It is therefore an opportune time to review the indications for hysterectomies, hysterectomy techniques and the present and future status of this surgical procedure. There is a widespread consensus that hysterectomies are primarily to be performed in cancer cases and obstetrical chaos situations even though minimal invasive surgical technologies (MIS) have made the procedure more patient friendly than the classical abdominal opening. Today, minimally invasive hysterectomies are performed as frequently as vaginal hysterectomies and the vaginal approach is the first choice if the correct indications are given. It is no longer necessary to open the abdomen; this procedure has been replaced by laparoscopic surgery. Laparoscopic and robotic-assisted laparoscopic surgery can also be indicated for hysterectomies in selected patients with gynaecological cancers. For women of reproductive age, laparoscopic myomectomies and numerous other uterine- preserving techniques are applied in a first treatment step of meno-metrorrhagia, uterine adenomyosis and submucous myoma. These interventions are only followed by a hysterectomy if the pathology prevails.","PeriodicalId":44130,"journal":{"name":"Clinical Medicine Insights-Reproductive Health","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4137/CMRH.S2980","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70697695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
