What is tortuous splenic vein?

What is tortuous splenic vein?

Splenic artery also called as the lienal artery, is the largest branch of celiac trunk. Branches of splenic artery supply the stomach, pancreas, and spleen. The difference in the increasing length of the artery and the distance between its origin and the splenic hilum makes the artery tortuous.

What causes dilated splenic vein?

The main cause of splenic vein stenosis is splenic vein thrombosis and thrombus formation accompanying the spread of inflammation from acute pancreatitis or chronic pancreatitis.

What causes splenic vein thrombosis?

The most common cause of isolated thrombosis of the splenic vein is chronic pancreatitis caused by perivenous inflammation. Although splenic vein thrombosis (SVT) has been reported in up to 45% of patients with chronic pancreatitis, most patients with SVT remain asymptomatic.

What is the normal size of portal vein?

The normal portal vein diameter (PVD) can vary normally between 7 to 15 mm while normal portal venous pressure lies between 5 and 10 mmHg (14 cm of H2O) (12). If portal venous pressure is more than 15 mmHg (30 cm of H2O), then it might indicate portal hypertension (12).

Where does the splenic vein go?

The splenic vein, here called the “lienal vein”, travels from the spleen, above the pancreas, and ends in the portal vein. The splenic vein (formerly the lienal vein) is a blood vessel that drains blood from the spleen, the stomach fundus and part of the pancreas. It is part of the hepatic portal system.

What does the splenic vein do?

The splenic vein drains the spleen, part of the pancreas, and part of the stomach.

How serious is splenic vein thrombosis?

Depending on the site of thrombosis, patients are at risk of developing liver insufficiency, portal hypertension, or bowel infarction and may experience recurrence in both the splanchnic veins and other vein segments.

How is splenic vein thrombosis treated?

Treatment of choice for bleeding gastric varices from splenic vein thrombosis is splenectomy [19]. Splenectomy at time of distal pancreatic resection is an accepted modality of treatment.

Is the splenic artery straight or tortuous?

– Spleen is a sub-diaphragmatic organ, so it moves with respiration. If the artery wasn’t tortuous, it would rupture. Yes, the splenic vein (of which the inferior mesenteric vein is the tributary) is straight. Veins, in general, are of less importance. Their rupture does not cause massive haemorrhage.

Why is the shape of the spleen tortuous?

In addition, the splenic artery gives rise to the left gastroepiploic artery, which runs along the greater curvature, and anastomoses with the right gastroepiploic artery . Maybe the Combination of those anatomical structures and functions had caused it shape to be tortuous. The fact is spleen moves with respiration and abdominal movements.

How can you tell if your splenic vein is dilated?

Splenomegaly due to splenic vein thrombosis. The dilated splenic vein (arrow) can be identified at the hilum (adjacent to the artery) containing echogenic thrombus and showing absence of colour flow.

Is the splenic vein superior to the pancreas?

It is a tortuous artery, running superiorly to the pancreas with the splenic vein inferoposteriorly before turning forward into the splenorenal ligament to the hilum of the spleen.

Which is the initiating event in splenic vein thrombosis?

Pancreatitis is found to be the initiating event that leads to the discovery of isolated splenic vein thrombosis in up to 65% of cases.46 Splenic vein thrombosis has also been described in association with abdominal trauma and after abdominal surgery.
