“…PV-1 was formed by the normal development and junction of the SMV and the SV, while PV-2 was independently derived from the SV. Such duplication of PV was consistent with previous reports [ 2 , 5 ]. However, this case has far more complex malformations in the PV system.…”

Background Duplication of the portal vein is a rare type of anatomic variant of the portal vein (PV) system that can be incidentally found and can lead to various challenges and consequences. Herein, we report an unusual case to increase our understanding of such anatomic variants. Case presentation A 67-year-old asymptomatic woman was diagnosed with a liver space-occupying lesion by ultrasonography on a routine physical examination. The laboratory examinations from a local hospital suggested that her liver function tests were normal. The liver appeared normal on pre-contrast enhanced CT images. However, there were multiple complex abnormalities of PV found on contrast-enhanced CT scans, including two independent sources of PV (duplication), preduodenal PV, circum-portal pancreas, mimic cavernous transformation, abnormal branches of PV, and transient abnormal perfusion in the left lobe of the liver. MRI showed fatty infiltration in the left lobe of the liver. Conclusion This case extends our current understanding of the anatomical variations of the PV system. Knowledge of these complex and rare anatomical variations will help clinical doctors make a confident diagnosis or assist with proper planning of a surgical procedure.

“…Therefore, the duplication of the portal vein is an uncommon, but a real developmental anomaly exemplifies how the portal vein malformation might occur during the embryological period to obtain the variation observed in this case (Figure ). The portal vein duplication has been described as a cause of portal hypertension and gastrointestinal (GI) bleeding . Although this complication did not occur in our patient, signs of hypertension mainly on the left portal system were identified in the pretransplant CT scan.…”

Portal vein malformations might occur during the embryonic period, as a consequence of abnormal remodeling of vitelline veins during embryonic life. Patients suffering from biliary atresia are particularly prone to have vascular malformations; although being the most frequent indication for liver transplantation in the pediatric age, portal vein duplication has not been so far associated with biliary atresia, and to the best of our knowledge, there is no‐written evidence describing how to manage it when it is first diagnosed while performing a pediatric liver transplant. Therefore, we present a recent case from our group, describing the intraoperative diagnosis of a double portal system in a patient with biliary atresia and failed Kasai. We aim to describe its surgical management, understanding that it is a real challenge to find them unexpectedly during the surgical procedure in the setting of cirrhosis and portal hypertension, particularly in small patients; therefore, by reporting this case, we aim to make readers aware about the chance of finding it, and how to managed it, to include this approach as part of the surgical armamentarium.

“…As far as we know, no literature or case reports have described a complete DPV which courses separately without any con uence to form a main trunk and supply the liver without tra c branches. Several types of DPV have been reported presenting with con uence or portal main trunk between the splenic and superior mesenteric veins [4][5][6]. Additionally, stenosis located in the distal potion of the residual ventral anastomosis, along with transient inhomogeneous perfusion and hypoplasia of segmental PV, were observed in this case.…”

A real and rare type of complete duplication of portal vein: a case report and literature review

Duplication of the portal vein is a rare type of congenital anomaly of the portal system. Herein, we present a rare type of complete portal vein duplication in a 71-year-old female patient complaining of longstanding abdominal distension and dyspepsia and illuminate the mechanism underlying severe complication in embryonic portal vein development. Interventional radiological procedures excluded other probable pathological alternations. Understanding the embryonic development of the portal vein and timely intervention are essential to manage such patients.
