As with the mesenteric veins, there is no direct and simple method to opacify the splenic and portal veins. A greater range of options is available to opacify these veins, however.65,67 Arterial portography is the most widely used method in which celiac (or selective splenic) and superior mesenteric arterial injections are performed, with high contrast volumes and filming carried into the venous phase. Other methods include percutaneous splenoportography and transhepatic or transjugular portography. Details of these techniques are given in the references.

A 48-year-old man with a history of alcohol excess is admitted with a variceal bleed. Regarding upper gastrointestinal varices, which of the following statements is correct? They are the result of hepatopetal blood flow from the left gastric vein and splenic vein to the superior mesenteric vein.Oesophageal varices tend to bleed more severely than gastric varices.Splenic portography is the first-line investigation for assessment.Barium studies can detect gastric varices in approximately 75% of cases evidenced by lobulated folds and polypoidal fundal masses.Gastric varices bleed more frequently than oesophageal varices.

o The timing of the images depends on whether the arterial or the portal phase is being investigated. Late-phase imaging is called indirect portography. The portal vein is visualized 60 s after contrast injection into the splenic or coeliac artery.

The SAE procedure has been described in detail previously [17,19]. All procedures were performed by the same interventional radiologist. After local disinfection and anesthesia, percutaneous right femoral artery puncture by the modified Seldinger technique was then performed. Next, a 5 F Yashiro catheter (Terumo, Tokyo, Japan) was used to perform arteriography of the celiac trunk, the superior mesenteric artery, and the splenic artery. Indirect portography was performed to observe the manifestations of the portal vein, the splenic vein, and the collateral circulation. Subsequently, a catheter was introduced into the main trunk of the splenic artery. After avoiding the feeding vessels of the pancreas, partial splenic embolization was performed to achieve infarction of up to 60–70% of the splenic volume using polyvinyl alcohol (PVA) particles (300–1000 μm) (Cook Incorporated, USA). The above was the first step.

All patients underwent standard preoperative investigations which included physical examination; double contrast-enhanced computed tomography (CT) scans of the chest, abdomen and pelvis; and CT portography or primovist magnetic reasonance imaging of the liver. Positron emission tomography was performed in all patients in addition to the stating laparoscopy to assess the PCI if the scans showed borderline results.

Potential surgical candidates underwent preoperative investigations which included physical examinations, blood tests, computed tomography (CT) scans of the chest, abdomen and pelvis. Additionally, patients with high-grade appendiceal tumors or raised tumor markers underwent either CT portography or MRI primovist and PET scan.
