Covered Stents for Late Postoperative Arterial Hemorrhage after Pancreaticoduodenectomy
Journal of Vascular and Interventional Radiology, 2009
The use of covered stents in treating delayed postoperative hepatic artery hemorrhage after pancreaticoduodenectomy may preserve hepatic arterial flow. The authors report two cases of massive hemorrhage after pancreaticoduodenectomy that were successfully treated with covered stents. Computed tomographic angiography demonstrated postprocedure patency of the hepatic arteries at 13 and 15 months, respectively. When technically feasible, percutaneous placement of stent-grafts may be used as a first-line intervention in delayed hemorrhage after pancreaticoduodenectomy.

The purpose of this study was to evaluate the clinical and long-term outcome of patients who underwent covered stent treatment because of late-onset postpancreatectomy hemorrhage in a greater number of patients. A secondary study goal was to compare embolization techniques with covered stents regarding differences in early and late clinical outcome, rebleeding, and vessel patency. Between December 2008 and June 2015, 27 consecutive patients suffering from major hemorrhage after pancreatic surgery underwent either covered stent placement or embolization of the affected visceral artery. The patients' medical reports and radiologic images were retrospectively reviewed. The main study end point was technical and clinical success, including survival and complications; the secondary end points were perfusion distal to the target vessel and, for covered stent placement, patency of the affected artery. Covered stent placement was successful in 14 of 16 patients (88%); embolization was s...

Postoperative hemorrhage is one of the most severe complications after pancreaticoduodenectomy. While detection of bleeding from adjacent arteries via conventional angiography and treatment with endovascular arterial coil embolization has been well established, to date no reports of percutaneous therapy for mesoportal hemorrhage have been published. This article describes an unusual case of delayed post-pancreaticoduodenectomy hemorrhage detected on a fluoroscopic drain check and treated with percutaneous transhepatic covered stent placement.
Successful embolization assisted by covered stents for a pseudoaneurysm following pancreatic surgery
World journal of gastrointestinal surgery, 2010
Delayed intra-abdominal hemorrhage after pancreatic surgery is a potentially lethal complication. Transarterial coil embolization and/or the placing of an endovascular stent are minimally invasive and effective procedures. An artery that is extensively eroded and rendered friable due to operative skeletonization or postoperative inflammation sometimes contributes to delayed intra-abdominal hemorrhage or rebleeding after coil embolization. This report presents a case of successful management of postoperative hemorrhage in a-74-year-old Japanese male. He experienced bleeding from a pseudoaneurysm of the brittle hepatic artery following total pancreatectomy. Initially the pseudoaneurysm was successfully treated with covered coronary stent-grafts, but rebleeding occurred 1 mo later due to the brittleness of the artery. Rebleeding was definitively managed by the complete packing of the stent by coil embolization. He remains stable at 18 mo following the final embolization. A stent graft ...

Background Delayed postpancreatectomy hemorrhage (PPH) is a fatal complication caused by arterial erosion. This study reports a single-center experience of managing delayed PPH with different endovascular treatment approaches. Methods We reviewed the data of patients who had delayed PPH due to hepatic artery or gastroduodenal artery stump perforation and underwent endovascular treatment between 2003 and 2018. We categorized endovascular treatment approaches involving hepatic artery sacrifice, superselective pseudoaneurysm embolization with hepatic artery preservation, and covered stent placement. Technical success rates, hemorrhage recurrence rates, major and minor hepatic complication rates, and 30-day and 1-year mortality rates were assessed. Results A total of 18 patients were reviewed; 11 (61%), 4 (22%), and 3 (17%) delayed PPH cases were managed through hepatic artery sacrifice, superselective pseudoaneurysm embolization, and hepatic artery stenting, respectively. Multidetector...

Massive arterial hemorrhage is, although unusual, a life-threatening complication of major pancreatobiliary surgery. Records of 351 patients who underwent major surgery for malignant pancreatobiliary disease were reviewed in this series. Thirteen patients (3.7%) experienced massive hemorrhage after surgery. Complete hemostasis by transcatheter arterial embolization (TAE) or re-laparotomy was achieved in five patients and one patient, respectively. However, 7 of 13 cases ended in fatality, which is a 54% mortality rate. Among six survivors, one underwent selective TAE for a pseudoaneurysm of the right hepatic artery (RHA). Three patients underwent TAE proximal to the proper hepatic artery (PHA): hepatic inflow was maintained by successful TAE of the gastroduodenal artery in two and via a well-developed subphrenic artery in one. One patient had TAE of the celiac axis for a pseudoaneurysm of the splenic artery (SPA), and hepatic inflow was maintained by the arcades around the pancreatic head. One patient who experienced a pseudoaneurysm of the RHA after left hemihepatectomy successfully underwent re-laparotomy, ligation of RHA, and creation of an ileocolic arterioportal shunt. In contrast, four of seven patients with fatal outcomes experienced hepatic infarction following TAE proximal to the PHA or injury of the common hepatic artery during angiography. One patient who underwent a major hepatectomy for hilar bile duct cancer had a recurrent hemorrhage after TAE of the gastroduodenal artery and experienced hepatic failure. In the two patients with a pseudoaneurysm of the SPA or the superior mesenteric artery, an emergency relaparotomy was required to obtain hemostasis because of worsening clinical status. Selective TAE distal to PHA or in the SPA is usually successful. TAE proximal to PHA must be restricted to cases where collateral hepatic blood flow exists. Otherwise or for a pseudoaneurysm of the superior mesenteric artery, endovascular stenting, temporary creation of an ileocolic arterioportal shunt, or vascular reconstruction by re-laparotomy is an alternative.

In recent years, even if the associated with pancreaticoduodenectomy mortality has been reduced still remains high. Delayed arterial hemorrhage after pancretoduodenectomy is defined as bleeding 5 or more days postoperatively. Pancreatic fistula and pseudoaneyrysm are the most common complications following pancreaticoduodenectomy and are present in most cases of delayed arterial hemorrhage. Most patients presented to ER with episodes of melena and hematemesis. Upper abdominal control by computer tomography, selective angiography of the celiac trunk and the evaluation of superior mesenteric artery set the diagnosis of pseudoaneurysm of the gastroduodenal of arterial stump. Delayed hemorrhage has more complex pathophysiology and requires a multiple management approaches. In this paper, we review the related to postoperative hemorrhage articles after major pancreatic surgery. Initial management, both diagnostic and therapeutic, should be done by angiographic control and trans-catheter ...

The objective of this study was to evaluate the effectiveness of endovascular treatment in patients presenting with late hemorrhage after pancreatectomy (LPPH). Material and method: Between 2008 and 2012, 53 percutaneous arterial procedures were performed in 42 patients with LPPH. There were 27 men and 15 women (mean age, 61.8 years ± 14.5 [SD]; range: 19-81 years). Clinical and technical success along with frequency of complications associated with the use of different endovascular techniques in patients with and without arterial anatomical variation were assessed. Results: Clinical success was observed in 35/42 patients (85%). The technical success was 37.5% in patients with anatomical variation versus 82.8% for those with modal anatomy (P = 0.003). Repeat bleeding (P = 0.029), complications (P = 0.013) and mortality (P = 0.045) were more frequent in patients with variation of celiac artery than in those with modal anatomy. For hepatic and gastroduodenal artery stump bleeding, the rate of complications was higher (60%) in the group treated by hepatic artery embolization (P = 0.028) by comparison with gastroduodenal artery stump selective embolisations or treatments by covered stent. A significant difference in mortality rate was found between patients with anatomical variations of celiac artery (36.4%) and those with normal anatomy (6.5%) (P = 0.032).

Objective The aim of the study was to assess the safety and efficacy of endovascular management for postpancreaticoduodenectomy hemorrhage. Materials and Methods A retrospective analysis of patients who underwent endovascular management for hemorrhage after pancreatic surgery between January 2015 to December 2020 was performed. Patient demographics, clinical presentation, angiography findings, endovascular procedure, technical success, clinical success, and complications were assessed. Results Seventeen patients, comprising 14 (82.4%) males and 3 (17.6%) females, aged 37 to 68 years underwent endovascular management for postpancreatectomy hemorrhage. Patients presented with hemorrhage on their postoperative days 4 to 22 (mean: 9.8th day; median: 8th day); the presentation was with extraluminal hemorrhage in 11 patients (64.7%) and intraluminal hemorrhage in 6 patients (35.2%). The gastroduodenal artery (GDA) stump (10 patients, 58.8%) was the most commonly involved artery. The major...
