Spontaneous hemorrhage due to pseudocysts of the pancreas

Hemorrhagic Pancreatic Pseudocysts

“…Sometimes two vessels are involved: for instance, the successive erosion of the gastroduodenal and then the pancreaticoduodenal arteries [ 14] and the portal and splenic veins [15]. Even very large vessels such as the aorta may be implicated [16][17][18], In our two observa tions, the artery concerned was the gastroduodenal ar tery.…”

“…In a few cases, abdominal auscultation revealed a pulsatile sound or murmur. Nevertheless, whether or not the palpated mass is pulsatile does not seem to be of prognostic value, since of 5 patients whose pseudocysts later ruptured into the peritoneal cavity [17,[21][22][23][24], only 1 [17] displayed this sign.…”

“…The pseudocyst may per forate into a hollow viscus or the pancreatic duct [25], or into the bile duct, causing hemobilia [26,27], The hem orrhage may be internal into the peritoneal cavity or the retroperitoneum [17]. Table 1 summarizes the 82 cases in which pseudocyst rupture into viscera or cavities has been observed.…”
