A causal analysis of intra-abdominal hemorrhage after reduced-size liver transplantation in rats
Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2020Co-Authors: Jiang Li, Sheng-ning Zhang, Zhu Li, Lai-bang Li, Li LiAbstract:To analyze the cause of abdominal hemorrhage after reduce-size liver transplantation in rats. Healthy female SD rats were used as the donors and male SD rats as the recipients (weighing 260-280 g), with the recipients weighing 10 g more than that of the donors. The donor operation was performed by the same surgeon under direct vision, and the liver graft size reduction procedure was completed in the donor operation. The recipient operation was performed by two surgeons under direct vision. A total of 270 SD rats received reduce-size liver transplantation successfully, and 44 of the rats died from intra-abdominal hemorrhage. The abdominal hemorrhages, listed in the order of incidences, included anastomotic hemorrhage of the inferior vena cava of the superior liver (28 cases), subcapsular hemorrhage of the liver (9 cases), ligation hemorrhage of the left outboard lobe, the nipple lobe and the triangle lobe of the liver (9 , 7 and 7 cases, respectively), hemorrhage of the right Suprarenal Vein and lumbar Veins (5 cases), hemorrhage of the mechanical injury (4 cases), cuff hemorrhage of the portal Vein and inferior Vein cava of the inferior liver (both 4 cases). Eight rats had anastomotic hemorrhage of the inferior vena cava of the superior liver and ligation hemorrhage of the left outboard lobe, 5 had hemorrhage of the two ligation points of the reduce-size liver; for management of the hemorrhage, 10 rats received suture or/and ligature, and 6 had washing and hot water bath. The most common cause of hemorrhage after reduce-size liver transplantation in rats is the anastomotic hemorrhage of the inferior vena cava of the superior liver, and this finding may provide clues for improving the success rate of reduced size liver transplantation in rats.

High Origin of Left Testicular Artery Associated with its Peculiar Arched course – A Rare Anatomical Variation
2020Co-Authors: Naveen Kumar, Satheesha B Nayak, Ashwini P Aithal, Ravindra S Swamy, Jyothsna Patil, Surekha D ShettyAbstract:Testicular arterial morphology deviating from its normal anatomy is a serious concern, as diagnostic approaches in male infertility and varicocele can be often linked with its associated vascular anomaly. We report here a case of remarkably high origin and peculiar course of left testicular artery in an elderly male cadaver aged approximately 60 years. The testicular artery arose from abdominal aorta at the level of origin of renal artery deep to renal Vein. In its further course it ascended obliquely upwards and to the left, behind the Suprarenal Vein. At the lateral border of Suprarenal Vein, it descended downwards by arching the renal Vein. It then coursed vertically downwards superficial to renal Vein. This peculiar course of testicular artery is vulnerable for iatrogenic injury during surgical approaches in this region. Prior knowledge of high origin and variant course of testicular artery is noteworthy before planning and performing any surgical and radiological interventions.

terminal bifurcation and unusual communication of left testicular Vein with the left Suprarenal Vein
Jornal Vascular Brasileiro, 2017Co-Authors: Satheesha B Nayak, Ashwini Aithal Padur, Naveen Kumar, Deepthinath ReghunathanAbstract:Variations of the testicular Veins are relevant in clinical cases of varicocele and in other therapeutic and diagnostic procedures. We report herein on a unique variation of the left testicular Vein observed in an adult male cadaver. The left testicular Vein bifurcated to give rise to left and right branches which terminated by joining the left renal Vein. There was also an oblique communication between the two branches of the left testicular Vein. A slender communicating Vein arose from the left branch of the left testicular Vein and ascended upwards in front of the left renal Vein and terminated into the left Suprarenal Vein. The right branch of the testicular Vein received an unnamed adipose tributary from the side of the abdominal aorta. Awareness of these venous anomalies can help surgeons accurately ligate abnormal venous communications and avoid iatrogenic injuries and it is important for proper surgical management.

rare combined variation of left Suprarenal vessels associated with retroaortic left renal Vein
Proceedings of Singapore Healthcare, 2016Co-Authors: Ravindra Swamy Shanthakumar, Naveen Kumar, Deepthinath Reghunathan, Satheesha Nayak Badagabettu, Mohandas Rao Kappettu Gadahad, Jyothsna PatilAbstract:Suprarenal vascular variations should be known to surgeons performing laparoscopic adrenalectomy, partial nephrectomy, living donor nephrectomy and renal transplantation. A rare case of vascular variation of the left Suprarenal gland was observed, in which the left Suprarenal Vein was draining into the inferior vena cava after crossing the abdominal aorta anteriorly, just below the origin of the superior mesenteric artery. The left inferior Suprarenal artery was originating from the left gonadal artery, which originated from the abdominal aorta in front of the left renal artery. Besides this, the left renal Vein passed obliquely downwards behind the abdominal aorta and drained into the inferior vena cava. The retroaortic left renal Vein may lead to unilateral hematuria, left varicocele and could be a cause of infertility in men.

Circumaortic left renal Vein and double right renal Vein: A case report
2015Co-Authors: Naveen Kumar, Satheesha B Nayak, Ashwini P Aithal, Ravindra S Swamy, Jyothsna PatilAbstract:Venous malformation of the kidney is not uncommon. However, bilateral variation of renal Veins is of rare occurrence and is clinically significant. In the present case, left renal Vein divided into left pre and retro-aortic renal Veins which passed in front and behind the abdominal aorta respectively, together forming a circumaortic renal Vein. The retro-aortic limb received left testicular Vein at a distance of 5.8 cm from inferior vena cava and pre-aortic Vein received left Suprarenal Vein at a distance of 4.2 cm from inferior vena cava. Pre-aortic and retro-aortic Veins drained into IVC separately about 4 cm apart from each other. On the right side, two separate renal Veins (superior and inferior) were present. Both of them drained into inferior vena cava separately and about 2.6 cm apart from each other. This aberrant pattern of renal Vein may affect the venous drainage of kidney and testis leading to renal hypertension and varicocele. Such variations should be known to urologists and surgeons before commencing any surgical and interventional procedures.

Anatomic bases for liver transplantation
Surgical and Radiologic Anatomy, 1991Co-Authors: Jm Chevallier, L. HannounAbstract:This study gathers the anatomic implications for a good liver transplantation. During hepatic removal a left hepatic a.exists in 20% of cases; a right hepatic artery originating from the superior mesenteric a. (SMA) can be the only arterial supply in 9% of cases; the whole lesser omentum has to be removed and the SMA from 6 cm to its origin. The SMA must be freed from the celiac ganglia and its ostium removed with the celiac trunk in an aortic patch cut on the anterior side in order to avoid the renal ostia. During total hepatectomy, dissection of the portal triad is often difficult because of portal hypertension dilating accessory portal Veins (parabiliary arcade) and pedicular lymphatics. Nerve plexuses are thick in front of the hepatic artery or behind the portal triad. Transection of triangular ligaments leads to the retrohepatic inferior vena cava (IVC) that must be freed from its posterior tributaries (right Suprarenal Vein and inferior phrenic Veins flowing either into the IVC or into the hepatic Veins). One big problem during hepatic replacement is the biliary anastomosis which must be well irrigated. In the recipient, dissection up to the hilum preserves hepatic and pancreatico-duodenal pedicles. The biliary tract of the graft must be cut low, behind the pancreas, and several centimeters of the gastroduodenal artery must be preserved to save hepatic and gastroduodenal pedicles.

Anatomic bases for liver transplantation
Surgical and Radiologic Anatomy, 1991Co-Authors: Jm Chevallier, L. HannounAbstract:Ce travail rassemble les notions anatomiques nécessaires au bon déroulement d'une transplantation hépatique. Le prélèvement du greffon doit enlever tout le petit omentum contenant une éventuelle a. hépatique gauche née de l'a. gastrique gauche (20%) et emporter l'a. mésentérique supérieure jusqu'à 6 cm de son origine pour ne pas oublier une a. hépatique droite née de cette dernière: son ostium est pris avec le tronc cœlique dans un patch aortique découpé sur la face antérieure. Lors de l'hépatectomie totale, la dissection du pédicule hépatique est rendue délicate par l'hypertension portale qui dilate les Veines portes diets accessoires (arcade parabiliaire) et les lymphatiques pédiculaires. Les plexus nerveux sont riches devant l'artère hépatique et derrière le pédicule. La section des ligaments triangulaires droit et gauche amène à la Veine cave inférieure (VCI) rétro-hépatique qu'il faut libérer de ses afférences postérieures (en particulier la Veine surrénale principale droite toujours haut située et les Veines phréniques inférieures qui s'abouchent soit dans la VCI soit dans les Veines hépatiques du carrefour). Lors du remplacement, l'anastomose biliaire doit être vascularisée. Chez le receveur la dissection jusqu'au hile permet de conserver les pédicules. La voie biliaire du greffon doit être coupée bas derrière le pancréas et les premiers centimètres de l'artère gastro-duodénale conservés pour préserver les pédicules hépatique et pancréaticoduodénal.
