Purpose The aim of the study is to assess the safety and clinical effectiveness of direct percutaneous embolization of visceral artery pseudoaneurysms.
Materials and Methods Retrospective analysis of patients who had undergone direct percutaneous embolization of visceral artery pseudoaneurysms between January 2012 and May 2017 was performed. The study included 26 patients with a mean age of 36 years (range 10–71 years). The indications for direct percutaneous embolization included the inability to catheterize endovascularly (n = 24) or prior embolization (n = 2) of the feeding artery. Patient demographics, details of the procedure, complications, and outcomes were evaluated. Patients were followed for a mean of 15 months to assess for recurrence of the pseudoaneurysms on ultrasound.
Results Splenic artery (n = 13), gastroduodenal artery (n = 4), right hepatic artery (n = 3), pancreaticoduodenal arteries (n = 3), left gastric artery (n = 2), and left hepatic artery (n = 1) were the embolized arteries. Etiology for pseudoaneurysm were pancreatitis (n = 20), trauma (n = 2), postoperative (n = 2), and few were incidentally detected (n = 2). N-butyl cyanoacrylate (NBCA) with lipiodol was used in 23 (88.4%) patients, coil in one (3.8%), and both coil and NBCA in two patients (7.7%). Embolization of the pseudoaneurysm was successful in all cases. No procedure-related complication was observed. Follow-up showed no recurrence of the pseudoaneurysm. Self-limiting splenic infarct was seen in six patients. Self-limiting abdominal pain was seen in all the patients with embolization with NBCA. One patient developed liver infarct and subsequent liver abscess requiring percutaneous drainage.
Conclusion Direct percutaneous embolization is safe and effective in the treatment of visceral artery pseudoaneurysms and should be considered as an alternative in patients with a failed endovascular approach.
Purpose The main purpose of this article is to assess the outcomes of endovascular management of pancreatitis-related hemorrhage.
Materials and Methods Retrospective analysis of patients referred for endovascular management of pancreatitis-related bleeding from January 2010 to December 2017 was performed. Patients’ demographics, clinical presentation, etiology, laboratory findings, angiography findings, details of the endovascular procedure, technical outcome, clinical outcome, and complications were assessed.
Results One hundred and five patients with a mean age of 37 years were included in this study. Splenic artery (41.7%) was the most commonly involved vessel. Middle colic, left colic, superior mesenteric, jejunal, left inferior phrenic, and left renal subcapsular arteries were the less commonly involved vessels. Embolization was performed using coils in 72 (68.5%) patients, n-butyl cyanoacrylate (n-BCA) in 21 (20%) patients, both coil and n-BCA in 8 (7.6%) patients, and 4 (3.8%) patients underwent stent graft placement. Technical success was achieved in 98% (n = 103) and clinical success in 93.2% (n = 96) of patients. Rebleeding was seen in 6.8% (n = 7) of patients. Six patients with rebleeding were managed by reintervention. Four patients had rebleeding from the same vessel, and two patients had rebleeding from a different vessel. One patient died due to massive rebleeding. Minor complications were seen in 14.2% (n = 15), major complications were seen in 3.8% (n = 4), and mortality rate was 0.9% (n = 1).
Conclusion Endovascular treatment is effective in the management of pancreatitis-related bleeding and is associated with low rebleeding rate and low mortality rate.
