The MPV is formed by the superior mesenteric vein and splenic vein
, is located in the right anterolateral of the inferior vena cava (IVC) and connects to the PS lateral and down to the DV origin in an oblique course from left to right (Fig.
aneurysms were first reported in 1953 (1) and they are part of the extrahepatic portal vein aneurysm group (2).
The functionality of splenic circulation was assessed by checking that the organ was bleeding only from the main splenic vein
. Keeping the blood pressure constant at 80 mmHg, the flow rate rapidly increased and became stable between 0.1-0.15 l/min for the duration of the perfusion (Fig.
An increased blood ammonia level and splenic vein
diameter are predictors for the presence of EV and risk factors for bleeding.
In subtype Ia there is no confluence of the SMV and splenic vein
, and each drains separately into a systemic, renal, or iliac vein (there is no anatomic portal vein).
Computed tomography (CT) scans and ultrasonography reports were reviewed; the radiologist's interpretation allowed for the determination of hepatic steatosis and splenic vein
Tumoral occlusion of the splenic vein
is clearly seen (asterisk, c).
Thereafter, the pancreas was then pulled superiorly and anteriorly, further revealing the superior mesenteric vein, the inferior mesenteric vein, and the splenic vein
located within the fusion fascia of Toldt.
Splenomegaly is associated with many diseases, but the etiology requires hematological studies on immune response work hypertrophy, red blood cell (RBC) destruction work hypertrophy, congestive (splenic vein
thrombosis or portal hypertension), myeloproliferative, infiltrative (benign or malignant) or purely neoplastic diseases.
PSE not only increases the platelet counts but also ameliorates portal hypertension and reduces esophageal varices by decreasing blood flow from the splenic vein
The remaining 5 (10%) needed conversion to open (causes being excessive bleeding from the splenic vein
, splenic capsular tear and excessively low platelet counts with gross oozing) (Table 2).
