Fogarty-assisted flow redirection during conventional transarterial chemoembolization for caudate lobe hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy. Approximately 8% of patients with HCC are not suitable candidates for curative options. Caudate lobe HCC presents technical challenges for interventional radiologists. Caudate lobe HCC has higher local recurrence and poorer survival rate than other segments. Transarterial treatments of caudate HCC are difficult due to extreme variation of arterial supply. We present a case of a caudate lobe HCC with supply from the proper hepatic artery, which underwent successful conventional transcatheter arterial chemoembolization (cTACE) by utilizing a Fogarty catheter to direct the embolic material. The patient presented 5 days following the procedure with duodenitis and pancreatitis, which were managed conservatively. Follow-up imaging at 1 month showed significant improvement of the ischemic duodenitis/pancreatitis with successful cTACE.

Transarterial embolization for traumatic splenic injury in a patient with a variant origin of splenic artery from the proper hepatic artery

A 57-year-old male patient was diagnosed with grade 2 spleen laceration and other multiple organ injuries after a rollover car accident. The patient was hemodynamically stable. Thus, transarterial embolization was performed to the splenic artery (SA). In angiography, the patient’s SA arised from a proper hepatic artery. The embolization finished successfully and the patient was discharged from the hospital on day 12 without any complications. Transarterial SA embolization may be feasible in patients who have varying SA origins even though the procedure is technically more challenging and a longer catheter may be needed compared to those of the usual case.

Anatomical variation in arterial supply of liver – Case study

The variations of blood supply of liver is of great importance for general surgery, particularly hepatic surgery. Blood supply of liver is significant for liver transplantations, radiological procedures, and laparoscopic method of operation and for the healing of penetrating injuries, including the space close to the hepatic area.The pattern of the normal vascular system of the liver comes from the common hepatic artery (CHA), originating from the celiac trunk. The gastroduodenal artery (GDA), right gastric artery (RGA) and proper hepatic artery (PHA) are the main branches of the CHA. After that, the division of the PHA composes the left and right hepatic branches.During a routine dissection with medical students from the Department of Anatomy, Parul institute of Medical sciences and research Vadodara, We found on one cadaver that the blood supply of the liver differed from a normal blood supply of liver.In one cadaver we found that liver is supplied by a direct branch from celiac trunk and in same cadaver liver is also supplied by proper hepatic artery. The knowledge about the variations in hepatic arterial anatomy is very important for surgical gastroenterologists and interventional radiologists for preoperative planning and intraoperative imaging during procedures like liver transplantation, cholecystectomy, gastrectomy, hiatal hernia repair, trans-arterial chemotherapy and hepatic arteriography.

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.

Complete embolisation of the proper hepatic artery for delayed haemorrhage after pancreaticoduodenectomy: a case report

Postpancreatectomy haemorrhage (PPH) is a rare and life-threatening complication that can occur after pancreaticoduodenectomy (PD). Recently, radiological intervention has become a first-line approach for the diagnosis and treatment of late PPH in haemodynamically stable patients. Surgical intervention should be performed in haemodynamically unstable patients. We report the case of a 54-year-old man who underwent PD for ampullary carcinoma. On postoperative day (POD) 20, he developed a late PPH in the context of pancreatic fistula that was accompanied by hypotension and tachycardia. Therefore, emergency relaparotomy was performed, but the bleeding site was not detected due to severe adhesions in the surgical field. Thus, urgent angiography was performed immediately, and active bleeding was detected from the distal part of the proper hepatic artery. Coil embolisation of the proper hepatic artery trunk was successfully performed. No intrahepatic abscess or liver failure was subsequently observed, and the patient left our hospital on POD 27. This case shows that radiological intervention is a first choice for the diagnosis and treatment of haemodynamically stable late PPH and that it also might still be a first choice and also be safer and more effective than surgical intervention even with unstable haemodynamics.
