PREOPERATIVE CONTROL OF SPLENIC ARTERY INFLOW IN PATIENTS WITH SPLENIC VENOUS OCCLUSION

Splenic vein occlusion due to chronic pancreatitis may result in “left-sided portal hypertension,” which is associated with gastric variceal hemorrhage. Intraoperative hemorrhage is also a major problem in this patient group, and it has been suggested that preoperative splenic arterial occlusion offers a means to diminish intraoperative blood loss. In order to assess the benefit of preoperative control of arterial inflow on intraoperative blood loss, we reviewed retrospectively 16 cases of chronic pancreatitis and associated splenic vein occlusion in patients who had splenectomy. There was a significant difference in estimated intraoperative blood loss in the two patient groups (P <.05). Preoperative inflow control was obtained with a wedge balloon catheter or autologous clot embolization with an estimated mean blood loss of 1771 mL in seven patients. Nine patients had splenectomy without inflow control, with a mean estimated intraoperative blood loss of 3332 mL. The mean difference was 1560 mL. Preoperative control of splenic artery inflow can diminish intraoperative blood loss during splenectomy in the presence of splenic vein occlusion associated with chronic pancreatitis. © 1990 Southern Medical Association.
