BACKGROUND Celiac trunk (CT) is the first major abdominal branch of the aorta. Anatomic variations and accessory vessels have been reported with variable percentages. We report here a particularly rare variant involving absence of the celiac trunk in association with trifurcation of the common hepatic artery (CHA). The purpose of this study was to report the pattern of the celiac trunk and its anatomic variations in a sample of Mysore population. METHODS Celiac trunk dissection was performed in 10 fresh cadavers and 50 cases of contrast enhanced computed tomography (CECT) images of Mysore based subjects at JSS Medical College and Hospital aged 18 years and above were included. Celiac trunk variations, length, diameter, accessory vessels, and vertebral level of origin were described. RESULTS The branching pattern of coeliac trunk was observed in 60 cases (37 males, 23 females) by dissection and CECT scan method. Type I was found in 48 cases (80 %), Type I form 2a was found in 2 cases (3.3 %). Type II form 1 in 6 cases (10 %). Type III was observed in 1 case and in another case left hepatic artery (LHA) arising from coeliac trunk, Type VII was found in 2 cases (3.3 %). The length and diameter of coeliac trunk were analysed using descriptive statistics and mean ± SD for length was 1.8 ± 0.4 and diameter 0.5 ± 0.2 respectively. CONCLUSIONS Awareness of CT variations is important in surgical resection, transplantation, and interventional radiology procedure.

Abstract Objective: To analyze the prevalence of anatomical variations of celiac arterial trunk (CAT) branches and hepatic arterial system (HAS), as well as the CAT diameter, length and distance to the superior mesenteric artery. Materials and Methods: Retrospective, cross-sectional and predominantly descriptive study based on the analysis of multidetector computed tomography images of 60 patients. Results: The celiac trunk anatomy was normal in 90% of cases. Hepatosplenic trunk was found in 8.3% of patients, and hepatogastric trunk in 1.7%. Variation of the HAS was observed in 21.7% of cases, including anomalous location of the right hepatic artery in 8.3% of cases, and of the left hepatic artery, in 5%. Also, cases of joint relocation of right and left hepatic arteries, and trifurcation of the proper hepatic artery were observed, respectively, in 3 (5%) and 2 (3.3%) patients. Mean length and caliber of the CAT were 2.3 cm and 0.8 cm, respectively. Mean distance between CAT and superior mesenteric artery was 1.2 cm (standard deviation = 4.08). A significant correlation was observed between CAT diameter and length, and CAT diameter and distance to superior mesenteric artery. Conclusion: The pattern of CAT variations and diameter corroborate the majority of the literature data. However, this does not happen in relation to the HAS.

Abstract Objective: To describe the main anatomical variations of the celiac trunk and the hepatic artery at their origins. Materials and Methods: This was a prospective analysis of 100 consecutive computed tomography angiography studies of the abdomen performed during a one-year period. The findings were stratified according to classification systems devised by Sureka et al. and Michels. Results: The celiac trunk was "normal" (i.e., the hepatogastrosplenic trunk and superior mesenteric artery originating separately from the abdominal aorta) in 43 patients. In our sample, we identified four types of variations of the celiac trunk. Regarding the hepatic artery, a normal anatomical pattern (i.e., the proper hepatic artery being a continuation of the common hepatic artery and bifurcating into the right and left hepatic arteries) was seen in 82 patients. We observed six types of variations of the hepatic artery. Conclusion: We found rates of variations of the hepatic artery that are different from those reported in the literature. Our findings underscore the need for proper knowledge and awareness of these anatomical variations, which can facilitate their recognition and inform decisions regarding the planning of surgical procedures, in order to avoid iatrogenic intraoperative injuries, which could lead to complications.

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.

Purpose. To investigate the extrahepatic collateral arteries related to hepatic artery occlusion (HAO) and to determine its benefits in the transarterial management of liver tumors.Methods and Findings. Eleven patients (7 hepatocellular carcinomas, 3 liver metastases, and 1 with hemangioma) with HAO confirmed with digital subtraction angiography (DSA) were admitted to our hospital. Of the 11 patients, 7 were men and 4 were women, with an average age of 41.5 ± 15.5 years (range: 29 to 70 years). DSA was performed to evaluate the collateral routes to the liver. In the 11 patients with HAO, DSA showed complete occlusion of the common hepatic artery in 9 patients and the proper hepatic artery (PHA) in 2 patients. Extrahepatic collateral arteries supplying the liver were readily evident. The collateral arteries originated from the superior mesenteric artery (SMA) in 8 patients, from the gastroduodenal artery in 2 patients, and from the left gastric artery (LGA) in 1 patient. Transcatheter treatment was successfully performed via the collateral artery in all patients except the one who had hemangioma.Conclusions. DSA is an effective method for detecting collateral circulation related to HAO and may provide information to guide transcatheter management decisions.

Introduction Symptomatic hepatic-artery pseudoaneurysm (HAP) after bile-duct injury (BDI) is a rare complication with a varied (but clinically urgent) presentation. Methods A prospectively maintained database of all patients with BDI at laparoscopic cholecystectomy (LC) referred to a tertiary specialist hepatobiliary centre between 1992 and 2011 was searched systematically to identify patients with a symptomatic HAP. Care and outcome of these patients was studied. Results Eight (6 men) of 236 patients with BDI (3.4%) with a median age of 65 (range: 54?6) years presented with symptomatic HAP. Median time of presentation of the HAP from the index LC was 31 (range: 13?16) days. Bleeding was the dominant presentation in 7 patients. One patient presented late (>2 years) with abdominal pain alone. Computed tomography angiography was the most useful investigation. Angioembolisation was successful in 7 patients. One patient died, and another patient developed liver infarction. Three patients (38%) developed biliary strictures after embolisation. Seven patients are alive and well at a median follow-up of 66 months. Conclusions Presentation of HAP is often delayed. A high index of suspicion is necessary for the diagnosis. Computed tomography angiography is the first-line investigation and selective angioembolisation can yield successful outcomes.

PURPOSE: Despite the fact that anatomical variations of the celiac trunk are well explored in the literature, information on these vessels diameters is scanty. The aims of the present study were to describe the arterial diameters of the celiac trunk and its main branches, and to investigate if these diameters are altered in those cases presenting anatomical variations of these vessels. METHODS: Twenty-one formalin fixed adult male cadavers were appropriately dissected for the celiac trunk identification and arterial diameter measurements. Arteries measured included the celiac trunk and its main branches (splenic artery, left gastric artery and common hepatic artery), as the proper hepatic artery, right gastric artery, the left and right hepatic arteries and the gastroduodenal artery. RESULTS: From the 21 cadavers, 6 presented anatomical variations of, at least, one of the above mentioned branches. The average arterial diameter comparisons between groups (normal and variable) clearly showed smaller diameters for variable vessels, but with no significant difference. CONCLUSION: Our data indicates the possibility of a diameter reduction of the celiac trunk main branches in the presence of anatomical variations. This should be taken into account on the selection for the liver transplantation donors.
