ABSTRACT
Hemosuccus pancreaticus is a rare cause of gastrointestinal bleeding from the pancreatic duct originating from aneurysms or pseudoaneurysms of peripancreatic arteries. It is a life-threatening cause of gastrointestinal bleeding that should always be considered in patients with prolonged or intermittent obscure gastrointestinal blood loss, or both, especially in patients with pancreatic disorders or prior pancreatic surgery. We demonstrate an endovascular treatment strategy in a patient with a common hepatic pseudoaneurysm and upper gastrointestinal tract bleeding, with preserved flow in the hepatic artery. This treatment consisted of a covered stent placement in the hepatic artery, followed by transcatheter coil embolization of collateral feeding arteries.

OBJECTIVE: Endovascular treatment of thoracic aortic disease may be associated with severe neurologic complications. The current study used the data of a multicenter registry to assess of the incidence and the risk factors for paraplegia or paraparesis and intracranial stroke. METHODS: The European Collaborators on Stent/Graft Techniques for Aortic Aneurysm Repair (EUROSTAR) database prospectively enrolled 606 patients. Thoracic pathologies with urgent or elective presentation, which included degenerative aneurysm in 291, aortic dissection in 215, traumatic rupture in 67, anastomotic false aneurysm in 24, and infectious or nonspecified disorders in 9. Study end points included evidence of perioperative spinal cord ischemia (SCI) or stroke. Univariate analysis and multivariate regression models were used to assess the significance of clinical factors that potentially influenced the occurrence of neurological sequelae. RESULTS: Paraplegia or paraparesis developed in 15 patients (2.5%) and stroke in 19 (3.1%); two patients had both complications. At multivariate regression analysis, independent correlation with SCI was observed for four factors: (1) left subclavian artery covering without revascularization (odds ratio [OR], 3.9; P = .027), (2) renal failure (OR, 3.6; P = .02), (3) concomitant open abdominal aorta surgery (OR, 5.5; P = .037) and (4) three or more stent grafts used (OR, 3.5; P = .043). In patients with perioperative stroke, two correlating factors were identified: (1) duration of the intervention (OR, 6.4; P = .0045) and (2) female sex (OR, 3.3; P = .023). A neurologic complication (paraplegia or stroke) developed in 8.4% of the patients in whom left subclavian covering was required compared with 0% of patients with prophylactic revascularization (P = .049). CONCLUSION: Perioperative paraplegia or paraparesis was significantly associated with blockage of the left subclavian artery without revascularization. The clinical significance of this source of collateral perfusion of the spinal cord had not been confirmed previously. Intracranial stroke was associated with lengthy manipulation of wires, catheters, and introducer sheaths within the aortic arch, reflected by a longer duration of the procedure.
