What is Splenoportography procedure?
Splenoportography is the radiographic examination of the venous system of the spleen and portal system of the liver after injection of contrast medium directly into the splenic vein or splenic parenchyma. The measurement of splenic pulp pressure before dye injection helps detect portal hypertension.
Why is Splenoportography done?
Splenoportography is a simple and safe diagnostic tool. The information obtained is important for planning an operation to relieve portal hypertension. It may also help in the postoperative evaluation of the patency of certain types of shunt procedures.
What is the portal circulation?
The portal vein drains almost all of the blood from the digestive tract and empties directly into the liver. This circulation of nutrient-rich blood between the gut and liver is called the portal circulation.
How do you investigate portal hypertension?
Clinically, patients with cirrhosis can be diagnosed with portal hypertension by the presence of ascites, varices, or both. Imaging studies such as Doppler ultrasonography, computed tomography, and magnetic resonance imaging also can aid in diagnosing portal hypertension and in defining portal vein anatomical features.
What organ is spleen?
The spleen is a small organ inside your left rib cage, just above the stomach. It’s part of the lymphatic system (which is part of the immune system). The spleen stores and filters blood and makes white blood cells that protect you from infection. Many diseases and conditions can affect how the spleen works.
What is splenectomy surgery?
Splenectomy is a surgical procedure to remove your spleen. The spleen is an organ that sits under your rib cage on the upper left side of your abdomen.
What are the 3 types of circulation?
3 Kinds of Circulation:
- Systemic circulation.
- Coronary circulation.
- Pulmonary circulation.
What are the 3 portal veins?
It is formed by the superior mesenteric vein, inferior mesenteric vein, and splenic vein.
What are the 3 categories of portal hypertension?
With regard to the liver itself, causes of portal hypertension usually are classified as prehepatic, intrahepatic, and posthepatic.
What are 5 The main symptoms of portal hypertension?
What are the symptoms of portal hypertension?
- Enlarged liver and spleen.
- Enlarged veins (varices) of the esophagus and stomach.
- Internal hemorrhoids.
- Weight loss from malnutrition.
- Fluid buildup in the belly (ascites)
- Kidney malfunction.
- Low platelets.
- Fluid on the lungs.
What are 3 diseases that affect the spleen?
Disorders of the spleen include splenomegaly, hypersplenism and splenic rupture.
Can you live without spleen?
The spleen is a fist-sized organ in the upper left side of your abdomen, next to your stomach and behind your left ribs. It’s an important part of your immune system, but you can survive without it. This is because the liver can take over many of the spleen’s functions.
What organ takes over after spleen removal?
If your spleen needs to be removed, other organs, such as the liver, can take over many of the spleen’s functions. This means you’ll still be able to cope with most infections.
What is the most common complication of splenectomy?
The most widely recognized long-term risk of splenectomy is overwhelming bacterial infection. More recently, thrombosis has become appreciated as another potential complication of the procedure.
What are the 4 circulatory systems?
The circulatory system consists of four major components:
- heart.
- arteries.
- veins.
- blood.
What is the largest artery in the body?
the aorta
How large is the aorta? The aorta is the largest blood vessel in your body. It’s more than 1 foot long and an inch in diameter at its widest point.
What size is a normal 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).
Can you live without a portal vein?
When the portal vein is absent, toxic metabolites such as ammonia and bile acids collected from the gastrointestinal tract have to bypass the liver directly drainage into the systemic circulation, thus may initiate hepatic encephalopathy.
Which drug is used in portal hypertension?
Pharmacologic therapy in the management of acute variceal hemorrhage
| Medication | Dosage |
|---|---|
| Vasopressin + Nitroglycerin | Intravenously (40 μg/min) or transdermally (10 mg in 24 h) |
| Terlipressin | Initial 48 h: 2 mg IV every 4 h until control of bleeding |
| Maintenance: 1 mg IV every 4 h for up to 5 d to prevent rebleeding |
What stage of liver disease is portal hypertension?
Portal hypertension is defined as the pathological increase of portal venous pressure, mainly due to chronic end-stage liver disease, leading to augmented hepatic vascular resistance and congestion of the blood in the portal venous system.
What is the most common cause of portal hypertension?
Portal hypertension is elevated pressure in your portal venous system. The portal vein is a major vein that leads to the liver. The most common cause of portal hypertension is cirrhosis (scarring) of the liver.
What foods heal the spleen?
Moderate quantities of cereals and pulses sustain good spleen function. Rice, wheat, quinoa, millet, buckwheat, lentils, dried beans, chickpeas and peas of all kinds should be eaten everyday. They can be accompanied by generous portions of vegetables, and sensible portions of meat or fish.
Where do you feel spleen pain?
Spleen pain is usually felt as a pain behind your left ribs. It may be tender when you touch the area. This can be a sign of a damaged, ruptured or enlarged spleen.
Can a spleen grow back?
Unlike some other organs, like the liver, the spleen does not grow back (regenerate) after it is removed. Up to 30% of people have a second spleen (called an accessory spleen). These are usually very small, but may grow and function when the main spleen is removed.
What is life expectancy after spleen removal?
Survival. When considering all cases, the median survival was 80 months. Following emergency splenectomy, the median survival was 72 months compared with 89 months following elective surgery (p=0.381) (Table 1).
