Biondetti P, Fumarola EM, Ierardi AM, Carrafiello G. Bleeding complications after pancreatic surgery: interventional radiology management. Gland Surg. 2019 Apr;8(2):150-163. doi: 10.21037/gs.2019.01.06.
Surgical intervention in the pancreas region is complex and carries the risk of complications, also of vascular nature. Bleeding after pancreatic surgery is rare but characterized by high mortality. This review reports epidemiology, classification, diagnosis and treatment strategies of hemorrhage occurring after pancreatic surgery, focusing on the techniques, roles and outcomes of interventional radiology (IR) in this setting. We then describe the roles and techniques of IR in the treatment of other less common types of vascular complications after pancreatic surgery, such as portal vein (PV) stenosis, portal hypertension and bleeding of varices.
Hassold N, et al. Effectiveness and outcome of endovascular therapy for late-onset postpancreatectomy hemorrhage using covered stents and embolization. J Vasc Surg. 2016 Nov;64(5):1373-1383.
RESULTS: Covered stent placement was successful in 14 of 16 patients (88%); embolization was successful in 10 of 11 (91%) patients. For the embolization group, the overall 30-day and 1-year survival rate was 70%, and the 1- and 2-year survival rate was 56%; for the covered stent group, these rates were 81% and 74%, respectively. The 30-day patency of the covered stent was 84%, and 1-year patency was 42%; clinically relevant ischemia was observed in two patients. Infarction distal to the embolized vessel occurred in 6 of 11 patients (55%).

One discussion this week involved etiologies of postpancreatectomy hemorrhage.
Reference: Yekebas EF, et al. Postpancreatectomy hemorrhage: diagnosis and treatment: an analysis in 1669 consecutive pancreatic resections. Annals of Surgery. 2007 Aug;246(2):269-280. doi:10.1097/01.sla.0000262953.77735.db
Summary: With the purpose of creating algorithms for managing postpancreatectomy hemorrhage (PPH), Yekebas et al (2007) restrospectively analyzed more than 1669 pancreatic resections conducted between 1992 and 2006. They concluded that the prognosis of postpancreatectomy hemorrhage (PPH) is primarily dependent on the presence of “preceding pancreatic fistula” (p.269).
