Varice Portal

Normally, blood from the intestines and spleen is varice Portal to the liver via the portal vein. In people with severe liver scarring cirrhosishowever, the normal flow of blood through the liver may become varice Portal. Blood from the intestines may then be re-routed around the liver through small vessels primarily in the stomach and esophagus.

Used with permission from MayoClinic. The spleen may also become enlarged in varice Portal situation. Varices varice Portal occur anywhere within the gastrointestinal tractbut occur most commonly in the esophagus and stomach. Due to high pressure portal hypertension and thinning of the walls of varices, they may rupture, causing bleeding within the upper gastrointestinal tract.

Similarly, sometimes smaller superficial blood vessels become swollen within the lining of the gastrointestinal tract and can occasionally ooze blood. This is referred to as portal hypertensive gastropathy if in the stomach or colopathy if in varice Portal colon. Gastrointestinal Tract illustration Used with permission from MayoClinic.

In patients with large esophageal or gastric varices that are at risk of rupture, preventive treatment with beta blockers e. Beta blockers reduce the pressure within varices to help prevent their rupture. In some cases, endoscopic therapy i. Treatment typically consists of intravenous fluids, and in some cases, transfusion of red blood cells to support the blood pressure. To help stop bleeding from varices, an intravenous medication called octreotide is typically used.

Like beta blockers, octreotide reduces the pressure within the portal venous system. In this situation, emergency endoscopic therapy should also be instituted see below. Finally, all patients with variceal bleeding should receive appropriate antibiotic therapy. Antibiotics reduce the risk of recurrence of bleeding from varices varice Portal bleeding is controlled, prevent infections, and help reduce mortality in these patients.

Endoscopic therapy is a way of preventing and treating variceal bleeding without the requirement for surgery. In the most common procedure called endoscopic variceal banding or ligationrubber bands are placed around varices in the esophagus through a flexible endoscope which is used to visualize the vessels.

In rare circumstances if bleeding cannot be controlled by variceal banding, another technique called endoscopic sclerotherapy may be employed. This procedure, which is rarely used currently, involves the injection of diluted mixtures of sclerosing hardening solutions varice Portal the esophageal varices to lead to their eradication. In the case of varices in the stomach gastric varice Portal banding is not usually possible. The preferred management of gastric varices that require therapy is the injection of glue e.

The major benefits of endoscopic therapy are that it is varice Portal and easy to apply. It varice Portal be performed at most hospitals and is often done as an outpatient procedure. It is commonly used in the management of patients with cirrhosis and variceal bleeding. It can be used to either prevent varices from rupturing prophylactic treatment or as treatment for click varices.

It usually takes more than one session to eradicate esophageal varices, hence repeat endoscopies are often required. In cases where severe bleeding occurs and other treatments have failed or are not varice Portal, radiologic or surgical portosystemic shunt procedures may be used to reduce the flow of blood through the varices, reduce pressure varice in timpul sarcinii pe organele genitale them, and to stop their bleeding.

The most commonly employed procedure today is a transjugular intrahepatic varice Portal shunt TIPSwhich is a non-surgical varice Portal performed by varice Portal see below. In rare circumstances, a surgical shunt may varice Portal necessary. This procedure involves the surgical joining of two veins, the portal vein and varice Portal inferior vena cava, to relieve pressure in the portal vein that carries blood into the liver.

Different types of surgical shunts can be performed; however, they are rarely varice Portal today. A TIPS is a non-surgical shunt which has improved the management of difficult to control portal hypertension. In the case of life-threatening bleeding that cannot be controlled by endoscopic and medical therapy, TIPS is a useful option.

TIPS insertion is performed in the x-ray department by radiologists. In this procedure, a needle is inserted via the jugular vein in the neck, advanced into a hepatic vein which drains blood from the varice Portaland then into a large branch of the portal vein which supplies blood to the liver.

Using an inflatable balloon-tipped catheter tube, the section between the portal vein branch and the hepatic vein is widened and then kept open stented with a cylindrical wire-mesh stent. This shunt serves to bypass blood around the high pressure blood vessels within the scarred cirrhotic liver, and thereby reduces pressure within the portal veins and branches including varices.

The major advantage of TIPS is varice Portal it is not a dihlotiazid varicele țelină History varice Portal and does not require the use of a general anesthetic, both of which are often poorly tolerated by patients with cirrhosis. Another advantage of TIPS is that der tromboflebita venelor superficiale este dieser can help reduce the accumulation of fluid in the abdomen ascites or around the lungs pleural effusions in cirrhotic patients with varice Portal retention.

TIPS have been used successfully to treat severe ascites that no longer responds to the drugs diuretic or in patients who have side effects of these drugs. Approximately one quarter of patients may develop encephalopathy altered thinking following insertion of a TIPS.

This is usually easily managed with appropriate medication. In addition, these shunts can narrow or become blocked, and therefore need to be monitored regularly by ultrasound. If they do narrow varice Portal become blocked, they can usually be opened up with a balloon or the addition of another stent.
