Can high blood pressure cause enlarged spleen?

Can high blood pressure cause enlarged spleen?

This syndrome is characterized by abnormal enlargement of the spleen (splenomegaly) due to obstruction of blood flow in some veins and abnormally increased blood pressure (hypertension) within the veins of the liver (e.g., hepatic or portal veins), or the spleen (splenic veins).

What blood tests show problems with the spleen?

Blood tests, such as a complete blood count to check the number of red blood cells, white blood cells and platelets in your system and liver function. Ultrasound or CT scan to help determine the size of your spleen and whether it’s crowding other organs. MRI to trace blood flow through the spleen.

What is the most common cause of massive splenic enlargement in adults?

Contributing factors include: Viral infections, such as mononucleosis. Bacterial infections, such as syphilis or an infection of your heart’s inner lining (endocarditis) Parasitic infections, such as malaria.

What can cause a mass on the spleen?

Spleen cancers are typically secondary, meaning that they originate elsewhere and then spread to the spleen. The most common causes of spleen cancer are lymphomas and leukemias. On occasion, other cancers, such as breast, lung, stomach, pancreatic, liver, or colon, are the source of the malignancy.

Does the spleen affect blood pressure?

By pursuing this hypothesis, we found that the spleen has an unprecedented role in hypertension, whereby the brain is connected to this secondary lymphoid organ to prime immune cells subsequently recruited to target organs crucial for blood pressure regulation.

Is there a blood test for spleen function?

Doctors can often tell if you have an enlarged spleen by feeling your abdomen. A blood test, CT scan or MRI scan can confirm the diagnosis. The spleen is not usually removed if it’s just enlarged. Instead, you’ll receive treatment for any underlying condition and your spleen will be monitored.

What autoimmune disease causes enlarged spleen?

Felty’s syndrome (FS), also called Felty syndrome, is rare autoimmune disease characterized by the triad of rheumatoid arthritis, enlargement of the spleen and low neutrophil count.

Can a mass in the spleen be benign?

Most common primary tumours of the spleen are benign and originate from the vascular endothelium and include haemangioma, hamartoma, littoral cell angioma, lymphangioma, haemangioendothelioma, haemangiopericytoma. Non-vascular tumours comprise the inflammatory pseudotumour, fibroma and lipoma [1–6].

Are spleen masses common?

Cysts of the spleen are the most common benign focal splenic masses. They are typically asymptomatic, but may enlarge and become painful. There are two types of cysts: true cysts and pseudocysts. Pseudocysts are much more common, representing 80% of all splenic cysts.

How does the spleen regulate blood pressure?

The spleen also helps to control the amount of blood circulating through the body by creating a reserve pool of blood that can be released during severe bleeding to help improve circulation, oxygenation and blood pressure in dire circumstances.

How does splenomegaly cause portal hypertension?

In this condition, splenomegaly is not only caused by portal congestion, but it is mainly due to tissue hyperplasia and fibrosis. The increase in spleen size is followed by an increase in splenic blood flow, which participates in portal hypertension actively congesting the portal system.

Does CT scan show portal hypertension?

Conclusions. Multi-slice CT serves as an important non-invasive imaging modality in the diagnosis of collaterals in cases of portal hypertension. CT portography can replace endoscopy in the detection of high-risk varices.

Can ultrasound detect portal hypertension?

Splenomegaly, ascites, and anatomy of intra- and extrahepatic portal vessels can reliably be detected by ultrasound in case of portal hypertension. The increased diameter of the portal vein and its roots is a not sufficient sensitive and specific finding in portal hypertension.

What are tests on the spleen function?

How is Feltys diagnosed?

Felty syndrome is usually diagnosed as a result of a thorough clinical evaluation, a detailed patient history, and the identification of the classic triad of physical findings (i.e. the presence of rheumatoid arthritis, low white blood count, and splenomegaly).
