Today’s topic is bleeding varices bleeding varices is a condition characterized by bleeding in abnormal vessels varices are abnormal connections between the systemic and portal circulation present in the body the system circulation takes blood to and from the heart to supply all other organs in the body while the portal circulation drains blood from the small

Intestine to pass through the liver before the rest of the body the abnormal connections are weak and prone to rupture which is usually a medical emergency and can be life-threatening varices commonly occur in the venous system but they may sometimes occur in arterial or lymphatic vessels the most common sight of varices is the esophagus although they can

Appear at other sites in the gastrointestinal tract such as the stomach rectum or around the belly button if the bleeding is not controlled fast a person may go into shock and eventually die serious complications such as coma pneumonia kidney failure and liver failure may occur even after the bleeding has been stopped causes bleeding varices is a life-threatening

Complication of high blood pressure in the portal vein a condition referred to as portal hypertension an increased pressure occurs in the portal vein as a result of blockage of blood flow throughout the liver this causes the development of large swollen veins or bera sees within the esophagus and stomach normally blood pressure in the portal vein is only about 5 to 10

Millimeters of mercury however this blockage can cause pressures to exceed 10 millimeters of mercury causing the blood vessels to dilate and form varices between different vessels this happens so the blood can bypass the obstruction and flow back to the systemic circulation and the heart if the blood pressure continues to increase and rise beyond 12 millimeters of

Mercury bleeding will occur at the varices because they have weaker walls as compared to normal blood vessels the common cause of portal hypertension is cirrhosis or scarring of the liver cirrhosis is caused by excessive consumption of alcohol or serious infections such as hepatitis 90% of cirrhosis patients will develop varices and about 30% will have a bleeding

Varices another condition that causes portal hypertension is portal vein thrombosis a condition where blood clots inside the portal vein symptoms excessive thirst vomiting which may contain blood paleness lightheadedness black-tar ii or bloody stools reduced urine output low blood pressure shock in some cases rapid heart rate diagnosis it is generally recommended

That patients with cirrhosis undergo screening for varices at the time of diagnosis and periodically some more small bera c’s are detected to make a diagnosis the doctor may perform an endoscope exam of the upper gastrointestinal tract to look for dilated veins if found the doctor will check for red streaks and red spots which may be indicative of a significant

Risk of bleeding imaging tests such as ct scans and ultrasounds treatment the goal of treatment options is to stop bleeding and prevent future bleeding treatment options may include banding in which elastic bands are used to tie off bleeding varices transjugular intrahepatic portosystemic shunt or tips a procedure in which x-ray is used to guide the placement of

A tubular device or shunt between the portal and hepatic vein creating a diversion for blood flow liver transfer for cases of an end-stage liver disease distal splenorenal shunt or d srs procedure to connect the splenic vein to the left kidney vein to control bleeding d vasculature to remove the bleeding varices blood transfusion to replace lost blood and clotting
