(2017a) stated: "Starting at 5 weeks, the portal (right vitelline vein), portal sinus and umbilical veins (intrahepatic portion) sprouted portal vein
branches that, at 6.5 weeks, have been pruned to 3 main branches inside the right hemi-liver, whereas all (>10) persisted in the left hemi-liver.
Unexpectedly, augmented collaboration of the portal vein
was demonstrated at the Calot triangle and the bed of the gallbladder during a laparoscopic cholecystectomy (LC) [Figure 1]a.
Sonographic imaging findings are nonspecific, but reversal of flow in portal veins
may be detected in some patients (21, 22).
Portal hypertension (PH) refers to a group of clinical syndromes characterized by abnormal changes of hemodynamics in portal vein
Croisille, "Post-partum thrombosis of the superior mesenteric and portal veins
, presenting as an abdominal mass," Journal de Radiologie, vol.
Abdominal computed tomography revealed intramural gas in the bowel and free gas in the mesenteric veins and portal vein
. Cranial computed tomography, which was performed due to impaired consciousness, demonstrated cerebral air embolism with the appearance of a gyriform pattern.
His portal vein
pressure was found to be only 16 mmHg, which did not indicate the need for a TIPS procedure.
In our patient, the imaging studies before splenectomy showed patent portal veins
. Previous studies have shown more than 30 causes of PSMVT, with pancreatitis being the most common [8, 9].
In the context of TACE, LPD that was delivered via the hepatic artery (HA) route could be almost always found in the portal vein
(PV) of the nontumorous liver [7-9].
Formation of portal vein
is by the confluence of the splenic vein with the superior mesenteric vein and its formation mostly occurs behind the pancreas in the retro peritoneum.
There was poor opacification of segmental branches of left portal vein
in segment II and III.
Sections of liver stained with haematoxylin and eosin, Van Gieson and Gomori's reticulin argentation revealed increased portal collagenous tissue, sclerosis and thrombosis of small branches of portal veins
, arterialisation of portal vein
and regenerative hyperplastic nodules (Figure 3 a & b).
