The right hepatic artery is an end artery and contributes sole arterial supply to right lobe of the liver. Misinterpretation of normal anatomy and anatomical variations of the right hepatic artery contribute to the major intraoperative mishaps and complications in hepatobiliary surgery. The frequency of inadvertent or iatrogenic hepatobiliary vascular injury rises with the event of an aberrant anatomy. This descriptive study was carried out to document the normal anatomy and different variations of right hepatic artery to contribute to existing knowledge of right hepatic artery to improve surgical safety. This study conducted on 60 cadavers revealed aberrant replaced right hepatic artery in 18.3% and aberrant accessory right hepatic artery in 3.4%. Considering the course, the right hepatic artery ran outside Calot’s triangle in 5% of cases and caterpillar hump right hepatic artery was seen in 13.3% of cases. The right hepatic artery (normal and aberrant) crossed anteriorly to the common hepatic duct in 8.3% and posteriorly to it in 71.6%. It has posterior relations with the common bile duct in 16.7% while in 3.4% it did not cross the common hepatic duct or common bile duct. The knowledge of such anomalies is important since their awareness will decrease morbidity and help to keep away from a number of surgical complications.

Vasculobiliary Injury

The frequency and significance of right hepatic artery injury associated with bile duct injury after laparoscopic cholecystectomy is unknown. Many reports suggest that a concomitant arterial injury worsens the outcome and prognosis of the bile duct injury even after an initially successful biliary repair. The optimal management of this complicated injury is controversial. We report a surgical technique to repair the right hepatic artery injury in these cases. We believe this technique is useful for surgeons who opt to repair the arterial injury at the time of biliary reconstruction, especially if it is performed soon after the injury occurred, before permanent damage to the liver and biliary system is established. To the best of our knowledge, this technique was not reported in the literature previously.

<p><strong>Objective. </strong>The aim of this study was to evaluate the utility of the Pulsatility Index (PI) of the right hepatic artery, measured by color Doppler sonography, in the diagnosis of acute cholecystitis.</p><p><strong>Methods. </strong>Seventy-five subjects were included in this study and divided into three groups, each consisting of 25 subjects: the cholecystitis group, the asymptomatic cholelithiasis group, and normal controls. Patients with acute cholecystitis fulfilled all the diagnostic criteria as stated in the latest Tokyo Guidelines. In all patients, the right hepatic artery was detected by color Doppler ultrasound and the PI was measured.</p><p><strong>Results</strong>. Patients with acute cholecystitis were found to have significantly higher PI values compared to both normal controls and cholelithiasis patients. Regression analysis revealed a significant positive correlation between the PI and the cholecystitis outcome.</p><p><strong>Conclusion. </strong>Measurement of PI by color Doppler ultrasound represents a useful aid in the diagnostic process of acute cholecystitis. More studies are needed before this method is incorporated in the relevant guidelines.</p>

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.
