Preduodenal portal vein, malrotation, and high jejunal atresia: a case report

Incomplete duodenal obstruction: a rare and late presentation

“…Since its first description 8 less than 100 patients of PDPV has been reported in the literature. 9 PDPV usually associated with other anomalies. Yi et al 10 reviewed the largest series of PDPV cases yet, with multiple associated anomalies reported including; intestinal malrotation in 64%, situs inversus in 26%, duodenal and pancreatic anomalies in 26% & 22% of them.…”

Duodenal obstruction due to a preduodenal portal vein

“…In PDPV, the portal vein passes anterior to the duodenum rather than posterior to it. [1][2][3][4][5][6][7][8] It is generally asymptomatic, but may co-exist with situs inversus and other anomalies like midgut malrotation, duodenal web, pancreatic, splenic or cardiac anomalies. [1][2][3][4][5][6]8] PDPV was first described in 1921 by Knight, and the majority of the reported cases in the literature are children presenting with duodenal obstruction.…”

“…[1][2][3][4][5][6]8] PDPV was first described in 1921 by Knight, and the majority of the reported cases in the literature are children presenting with duodenal obstruction. [1][2][3][4][5][6][7][8] The portal vein arises during foetal life by a systematic absorption of the interconnecting veins of the vitelline venous system. The two parallel vitelline veins are joined by three interconnecting veins-the cephalad branch within the liver, the middle branch posterior to duodenum, and the caudal branch anterior to duodenum.…”

“…[9] The presence of PDPV should alert the radiologist to look for other associated anomalies that can lead to duodenal obstruction, and this will direct further imaging studies. [1][2][3][4] The preferred treatment of duodenal obstruction caused by PDPV is duodeno-duodenostomy. [1][2][3]7,8] This procedure was performed in our patient.…”
