The patients with SpVO had significantly larger splenic volumes and lower platelet counts. Compared to the patients with patent splenic veins (SpVs), the patients with SpVO underwent significantly longer operations (<jats:italic>p<\/jats:italic>\u2009=\u20090.006), with a higher incidence of postoperative complications (<jats:italic>p<\/jats:italic>\u2009=\u20090.002). We classified the collateral routes associated with SpVO into five patterns. The most common pattern was the left gastroepiploic vein type, which was associated with a tumor of the pancreatic body. In patients with PDAC, SpVO was associated with larger tumors, microscopic vascular permeation, and peritoneal recurrence. However, the differences between overall and recurrence\u2010free survival rates in the patients with SpVO vs those with patent SpVs were not significant.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>SpVO causes left\u2010sided portal hypertension, which can be a risk for perioperative complications in DP.
