Of these, 22 patients (age, 63\u2009\u00b1\u200910 years) with jejunal variceal bleeding caused by portal vein obstruction after surgery were included in this study. Computed tomography (CT) findings before and after treatment and the rates of technical and clinical success, complications, and clinical outcomes were retrospectively evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Stent placement was successful in 19 of 22 patients. Additional variceal embolization was performed in five cases. Clinical success, defined as the cessation of bleeding without recurrence within 1 month, was achieved in 18 of 19 patients with technical success. One patient developed recurrent bleeding 4 days after stent placement and was successfully treated with additional variceal embolization. There were no procedure-related complications. A regression of the jejunal varices was noted in 14 of 19 patients on follow-up CT scans. During the follow-up period (258 days; range, 7\u20131196 days), stent occlusion and recurrent bleeding occurred in six and four patients, respectively, of the 19 patients who achieved technical success. Statistical analyses revealed no significant differences regarding stent patency between benign and malignant strictures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
