Multidisciplinary Approach to Pseudoaneurysms Complicating Pancreatic Pseudocysts

Abstract

Before endoscopic drainage of a pancreatic pseudocyst, a thin-section, high-speed, dynamic-contrast computed tomographic scan is essential. If there are findings consistent with the development of a pseudoaneurysm, angiography must be performed. This allows delineation of the arterial anatomy, as well as the option of performing angiographic embolization. While patients with pseudoaneurysms in the body and tail of the pancreas underwent resection, angiographic embolization alone was an acceptable alternative when the lesion was located in the head of the pancreas.

Endovascular Treatment of Arterial Bleeding in Patients with Pancreatitis

“…High clinical success rates at the 3-month follow-up as well as low morbidity and mortality rates confirm the results reported in the literature ( table 4 ) [8,31] . Comparing our results with surgical ones in the literature, endovascular treatment appears to be less invasive and at least as successful as surgery.…”

“…It is extremely difficult to collect a sufficient number of cases in the same center and conduct a prospective comparative clinical trial. In order to reduce the impact of this bias, we compared our results with other reports in the literature, both surgical and endovascular [5,10,25,[29][30][31][32][33][34][35] ( table 4 ).…”

Unusual locations of pseudo aneurysms as a sequel of chronic pancreatitis

“…5 The highlight of this case series is uncommon locations of pseudoaneurysms involving SMA and IPA in the setting of chronic pancreatitis. SMA pseudoaneurysm has been reported in literature in different clinical settings like post pancreatic surgery and acute or chronic pancreatitis.…”

Minute Splenic Pseudoaneurysm Causing Hemorrhage within a Pancreatic Pseudocyst: The Utility of CT during Splenic Arteriography

“…In the same series [11], contrast-enhanced CT detected a false aneurysm in 16 of 73 cases (22%). Marshall [12] discussed the detection of false aneurysms in five cases with bleeding pancreatic pseudocysts as follows: two cases (40%) in dynamic CT and four cases (80%) in angiography. Kin-Chun [13] performed CT for a close inspection of bleeding from false aneurysms complicated with chronic pancreatitis, and he reported false aneurysms in only four of seven patients (57%).…”
