Abstract
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.

Abstract
Surgical treatment of pancreatic diseases is always associated with a large number of complications. Postoperative hemorrhage is a specific complication of pancreatic surgery requiring a clear classification and surgical strategy. According to literature data, postoperative hemorrhage occurs in 3-30% of cases. Incidence of hemorrhages depends on intraoperative, anamnestic, histological and postoperative factors. Early postoperative hemorrhage (within 24 hours after surgery) is usually a consequence of technical errors in intraoperative hemostasis, perioperative coagulation disorders. The mechanism of delayed bleeding is more complex and often associated with various arrosive factors: pancreatic fistula, biliary fistula, abscess. Currently, there is no a single treatment algorithm for patients with postpancreatectomy hemorrhage. According to various researchers, contrast-enhanced CT is preferred for diagnosis. In recent years, the role of endovascular hemostasis has significantly increased. This problem requires further study and development of a single treatment and diagnostic algorithm that will reduce mortality in these patients.

Abstract
PURPOSE To evaluate the outcomes of emergency endovascular treatments for delayed bleeding after pancreaticobiliary surgery. METHODS We retrospectively evaluated 21 patients (M:F = 13:8, median age = 64 years) undergoing 23 endovascular treatments, performed from 2010 to 2017 in a single center. Data collected were patient characteristics; surgery; pathology; incidence of postoperative pancreatic fistulas (POPF); bleeding signs on CT and angiography; damaged artery; endovascular tools used; technical and clinical success; intervals between surgery, endovascular treatment, and discharge; survival rates. RESULTS Sixteen patients had pancreatoduodenectomy, three hepaticojejunostomy, two distal pancreatectomy. Indications for surgery were mainly biliary (33%), pancreatic (19%), or duodenal (10%) malignancies. Seventeen patients had "grade C" POPF, three suffered a biliary leak, one had no POPF. Active bleeding was present in 17/23 CTs and in 22/23 angiographies, mostly from hepatic (43%), gastroduodenal (22%), and splenic (13%) arteries. The endovascular treatments were performed with coils (26%), glue (22%), stent-graft (22%), and their combinations (30%). Sixteen patients had a single endovascular treatment, one underwent a second embolization, three had subsequent surgery, one had repeat embolization followed by surgery. Relaparotomy rate was 19%. Median hospital stay was 37 days (range 12-75); median intervals among pancreaticobiliary surgery, endovascular treatment, and discharge were 21 (2-36) and 12 (8-47) days, respectively. We observed 4/21 intrahospital deaths (median: 31 days from endovascular treatment, 4-53); 1-year survival rate of discharged patients was 71%. CONCLUSIONS Endovascular treatment using embolization and/or stent-graft placement is a useful first-line intervention to halt postoperative hemorrhage after pancreaticobiliary surgery and decreases the need for urgent relaparotomy.

Abstract
OBJECTIVE To explore the role of interventional radiology (IR) in the management of late postpancreaticoduodenectomy hemorrhage (PPH). MATERIALS AND METHODS Patients who had late PPH (occurring >24 h after index operation) managed by the IR procedure in our institution between 2013 and 2018 were retrospectively analyzed. RESULT Hired patients who were diagnosed with grade B (n = 10) and C (n = 22) late PPH underwent 40 transcatheter arterial angiographies (TAA). The overall positive rate of angiography was 45.0% (18/40). Eighteen transcatheter arterial embolizations (TAEs) were performed, and the technical success rate was 88.89% (16/18). The rebleeding rate after embolization was 18.8% (3/16), and no severe procedure-related complications were recorded. The overall mortality of late PPH was 25.0% (8/32). CONCLUSION Nearly half of hemorrhagic sites in late PPH could be identified by TAA. TAE is an effective and safe method for the hemostasia of late PPH in patients with positive angiography results.

Abstract
Objective To explore the diagnostic value of digital subtraction angiography (DSA) and the effectiveness of endovascular treatment for a post-pancreaticoduodenectomy hemorrhage (PPH). Results During the DSA examination, positive results were found in 29 patients, yielding a positive rate of 69.0%. The manifestations of the DSA examination included contrast medium extravasation, pseudoaneurysm, and artery walls coarse. All 29 patients with positive results underwent endovascular treatment, including transartery embolization (TAE) in 28 patients and covered stents placement in one patient. The technical success and clinical success rates were 100% and 72.4%, respectively. Re-bleeding occurred in 8 of the 29 patients after the first treatment (27.6%). The mortality of PPH was 17.2% (5 of 29). Two of the five PPH patients died following severe infections, and three died from multiple organ failure. Materials and Methods A DSA examination was conducted using clinical and imaging data of 42 patients, and endovascular treatment for delayed PPH was retrospectively analyzed. Conclusions DSA examination is a minimally invasive and rapid method for the diagnosis of delayed PPH. For patients with positive DSA results, endovascular treatment can be performed rapidly, safely, and effectively. Therefore, the DSA examination and endovascular treatment could be considered a preferred treatment approach for delayed PPH.

Abstract
BACKGROUND AND AIMS Hemorrhage is a rare but dreaded complication after pancreatic surgery. The aim of this study was to examine the incidence, risk factors, management, and outcome of postpancreatectomy hemorrhage in a tertiary care center. MATERIALS AND METHODS A retrospective observational study was conducted on 500 consecutive patients undergoing major pancreatic resections at our institution. Postpancreatectomy hemorrhage was defined according to the International Study Group of Pancreatic Surgery criteria. RESULTS A total of 68 patients (13.6%) developed postpancreatectomy hemorrhage. Thirty-four patients (6.8%) had a type A, 15 patients (3.0%) had a type B, and the remaining 19 patients (3.8%) had a type C bleed. Postoperative pancreatic fistula Grades B and C and bile leakage were significantly associated with severe postpancreatectomy hemorrhage on multivariable logistic regression. For patients with postpancreatectomy hemorrhage Grade C, the onset of bleeding was in median 13 days after the index operation, ranging from 1 to 85 days. Twelve patients (63.2%) had sentinel bleeds. Surgery lead to definitive hemostatic control in six of eight patients (75.0%). Angiography was able to localize the bleeding source in 8/10 (80.0%) cases. The success rate of angiographic hemostasis was 8/8. (100.0%). The mortality rate among patients with postpancreatectomy hemorrhage Grade C was 2/19 (10.5%), and both fatalities occurred late as a consequence of eroded vessels in association with pancreaticogastrostomy. CONCLUSION Delayed hemorrhage is a serious complication after major pancreatic surgery.Sentinel bleed is an early warning sign. Postoperative pancreatic fistula and bile leakage are important risk factors for severe postpancreatectomy hemorrhage.

Abstract
PURPOSE Hepatic artery pseudoaneurysms are a rare but potentially life-threatening complication of major pancreaticobiliary surgery. We evaluated the safety and efficacy of endovascular stentgraft implantation for the management of such vascular lesions. MATERIALS AND METHODS Between May 2013 and October 2015, ten patients with postoperative hepatic artery pseudoaneurysm, of which eight presented with active hemorrhage, were treated with endovascular stentgraft implantation. All patients had undergone major pancreatic or hepatic surgery before (pylorus-preserving pancreaticoduodenectomy, pancreatectomy, hemihepatectomy, extended hemihepatectomy). The pseudoaneurysms were diagnosed 13-202 days after surgery and were associated with postsurgical complications (e.g., leakage of pancreaticojejunal anastomosis). RESULTS In 9/10 patients, the pseudoaneurysm was completely excluded via stentgraft implantation. In 1/10 patient, the pseudoaneurysm ruptured during the procedure and was successfully treated by immediate open surgery. In 1/10 patient, a second intervention was performed after 6 days because of rebleeding; this was successfully treated by implantation of a second overlapping stentgraft. Mean follow-up time is 51 days. None of the patients died due to stentgraft- or aneurysm-related complications. Further episodes of hemorrhage were not observed. In one patient, clinically asymptomatic complete occlusion of the stentgraft was discovered at follow-up imaging. CONCLUSION Stentgraft implantation is a safe and effective technique to treat hepatic artery pseudoaneurysms related to major pancreatic or hepatic surgery, especially in the setting of acute hemorrhage.
