Calot’S Triangle

BACKGROUND: Lap cholecystectomy is gold standard for cholelithiasis. Earlier the incidence ofmorbidity and mortality was higher. Later on with the understanding of anatomy and fine techniquesboth morbidity and mortality decreased. Understanding of the anatomy of calot’s triangle reduces thecomplications of the procedure.OBJECTIVE: To study the pattern of variations in cystic artery and comparison with Caucasians.MATERIAL AND METHODS: All laparoscopic cholecystectomies performed in Shah MedicalCentre,over a period of 1 year from January 2013 to December 2013,in whom detailed anatomy ofcalot’s triangle was clearly displayed were included in the study. Those laparoscopic cholecystectomiesin whom the detailed anatomy was not clear were excluded from the study.Laparoscopic cholecystectomies were performed under general anesthesia. The anatomy of cystic arteryand its branches were identified, and it was also correlated in relation to cystic duct and common hepaticduct.We performed 240 lap cholecystectomies over a period of 1 year from January 2013 to December 2013.RESULTS: The pattern of cystic artery was studied in 240 laparoscopic procedures. Origin of cysticartery from right hepatic artery was observed in 82% cases. Double cystic arteries were observed in 8%cases. Common hepatic artery gave rise to 6% cystic arteries. Cystic arteries originated fromgastroduodenal artery in 3% cases. Hepatic parenchyma gave rise to 2% cases.CONCLUSION: Percentage of variations in cystic artery as compared to Caucasians are not different inour study.These variations should be kept in mind to reduce complications.KEYWORDS: laparoscopic cholecystectomy, calot’s triangle, hepatic artery, cystic artery.

BACKGROUND Cystic artery originates from right hepatic artery which is a branch of hepatic artery proper of coeliac trunk from abdominal aorta. Variations in the origin and course of cystic artery were observed in this study. Contents of Calot’s triangle were also studied. Knowledge of normal anatomy, variations of the biliary apparatus and the arterial supply to the gallbladder is important for surgeon. METHODS Descriptive cross-sectional study was done from April 2008 to January 2010 in 180 adult specimens and 50 foetal specimens in the Departments of Anatomy, Forensic Medicine and Pathology in Government Medical College, Thiruvananthapuram. The abdominal wall was incised and hepatobiliary region was identified and dissected. The gallbladder and coeliac trunk were identified. Cystic artery and Calot’s triangle were studied. RESULTS More than 90 percent of the cystic artery originates from the right hepatic artery in both sexes. Cystic artery originated from left hepatic artery in 4 cases, common hepatic artery in 5 cases and from middle hepatic artery in 1 case. The cystic artery within Calot’s triangle was observed in 41 %. Right hepatic artery was content in 29.9 %. Both the arteries were content in 19 %. Cystic artery and accessory hepatic duct were content of Calot’s triangle in 2.2 %. Double cystic artery was content of the triangle in 1 cadaver. Artery or duct was seen outside the Calot’s triangle in 16 cadavers. CONCLUSIONS It is important for surgeons to know the variations of cystic artery and Calot’s triangle during surgical interventions of the hepato biliary region. “Cystic artery syndrome” is a condition where cystic artery is seen winding around cystic duct although it originates from right hepatic artery. Knowledge of these variations is important for surgeons and helps in better surgical outcome. KEYWORDS Cystic Artery, Calot’s Triangle, Right Hepatic, Gall Bladder, Coeliac Trunk

Abstract Background and aims : The right hepatic artery occasionally forms a sinuous tortuousity called as caterpillar hump or Moynihan's hump, which occupies the major portion of Calot's triangle. Due to this variation, inadvertent injury to right hepatic artery may occur during surgical procedures. The aim of the study is to find out the incidence of Caterpillar hump of right hepatic artery in cadavers and to correlate with surgical significance. Materials and methods : Sixty cadavers allotted for the purpose of teaching undergraduate students from the period of 2006 to 2011 were used for this study. Branches of coeliac trunk were traced and right hepatic artery was observed for the presence of caterpillar hump. Results : Caterpillar hump was noted in three out of 60 cadavers (5%). Out of three specimens with caterpillar hump, right hepatic artery passed posterior to common hepatic duct in two specimens and anterior to it in one specimen. The presence of dual loops of right hepatic artery was noted in two specimens and single loop was observed in one specimen. Conclusion: The presence of this variant course of right hepatic artery may lead to the formation of short cystic artery. Thereby, right hepatic artery can be mistaken for cystic artery and may be injured during surgical procedures. The knowledge of caterpillar hump of right hepatic artery is essential for the surgeons to avoid the risk of ischemic necrosis of right lobe of liver.

Percutaneous Trans-Hepatic Embolization of an Iatrogenic Extra-Hepatic Pseudoaneurysm of the Right Hepatic Artery in a Patient With Previous Occlusion of the Proper Hepatic Artery: An Endovascular Procedure to Avoid a Difficult Surgical Repair

We report a case of successful percutaneous transhepatic, embolization of an iatrogenic extra-hepatic pseudoaneurysm (PsA) of the right hepatic artery (RHA) under combined fluoroscopic and ultrasonographic guidance. A 73-year-old man underwent percutaneous transhepatic biliary drainage placement in another hospital, complicated by haemobilia and development of a RHA PsA. Endovascular embolization was attempted, resulting in coil embolization of the proper hepatic artery, and persistence of the PsA. At this point, the patient was referred to our hospital. Computed tomography and direct angiography confirmed the iatrogenic extra-hepatic PsA of the RHA, refilled by small collaterals from the accessory left hepatic artery (LHA) and coil occlusion of the proper hepatic artery. Attempted selective catheterization of these vessels was unsuccessful due to the tortuosity and very small caliber of the intra-hepatic collaterals, the latter precluding endovascular treatment of the PsA. Percutaneous trans-hepatic combined fluoroscopic and ultrasound-guided embolization of the PsA was performed with Lipiodol® and cyanoacrylate-based glue (Glubran®2). Real time fluoroscopic images and computed tomography confirmed complete occlusion of the pseudoaneurysm. Surgical repair, although feasible, was considered at high risk. In our patient, we decided to perform a percutaneous trans-hepatic combined fluoroscopic and ultrasound-guided embolization of the PsA using a mix of Lipiodol® and Glubran®2 because of the fast polymerization time of the glue allowing the complete occlusion of the PsA in few seconds, thus eliminating the risk of coil migration, reducing the risk of PsA rupture and avoid a difficult surgical repair.

The arterial supply of the gallbladder usually arises from the right hepatic artery. Other origins include the left, proper, and common hepatic arteries. We report cases of the cystic artery arising from the superior mesenteric artery and arising from the dorsal pancreatic artery originating in turn from the superior mesenteric artery, as demonstrated by angiography and computed tomography.

An 80-year-old male patient presented with sepsis secondary to infected central line which was placed for native aortic valve endocarditis. He also had melena and abdominal pain prior to his presentation. Abdominal computed tomography (CT) was done, which showed cholelithiasis. Esophagogastroduodenoscopy was also done with no source of bleeding identified. Later, he developed hemodynamic instability requiring aggressive fluid resuscitation and multiple packed blood cell transfusions. In view of his hemodynamic instability, a repeat abdominal CT scan showed air droplets within the gallbladder pneumobilia, ascites, diverticulosis, and a bleeding infrahepatic hematoma measuring 6 × 10 cm, which was not on his prior scan 2 days prior. A mesenteric arteriogram was performed that identified an aneurysm of the right hepatic artery with no active bleeding; therefore, it was coiled. Due to his continued clinical decompensation, he underwent an urgent open cholecystectomy, in which serosanguineous fluid, cholecystocolic fistula, and old clot related to his previous bleed were encountered. However, control of bleeding was difficult, and the patient expired. We report this case of right hepatic artery aneurysm that we believe its etiology was related to eroding cholecystitis.
