•Active bleeding or bleeding diathesis.
Plasminogen activator inhibitor-1 (PAI-1) deficiency is a rare inherited autosomal recessive bleeding disorder.

Esophageal varices are dilated blood vessels within the wall of the esophagus. Patients with cirrhosis develop Portal Hypertension. When Portal Hypertension occurs, blood flow through the liver is diminished. Thus, blood flow increases through the microscopic blood vessels within the esophageal wall. As this blood flow increases, the blood vessels begin to dilate. This dilation can be profound. The original diameter of the blood vessels is measured in millimeters while the final, fully established, esophageal varix may be 0.5 to 1.0 cm or larger in diameter. Bleeding varices are a life-threatening complication of portal hypertension (increased blood pressure in the portal vein caused by liver disease). Increased pressure causes the veins to balloon outward. The vessels may rupture, causing vomiting of blood and bloody stools or tarry black stools. If a large volume of blood is lost, signs of shock will develop. Any cause of chronic liver disease can cause bleeding varices.
Although overall survival may be improving, mortality is still closely related to failure to control hemorrhage or early re-bleeding.
Factors that influence this failure include severity of liver disease and active bleeding during endoscopy.
In addition increased portal pressure has been proposed as a prognostic factor of early re-bleeding.

This patient has lager esophageal varices as well as gastric varices.
These blood vessels then continue to dilate until they become large enough to rupture. When esophageal varices rupture, patients become acutely ill. In fact, 50 percent of patients with esophageal varices will eventually bleed from the varices. The mortality rate for esophageal variceal bleeding, on the first event, is between 40 and 70 percent. Mortality is due to multiple factors.
Esophageal varices are distended submucous veins that project into the esophageal lumen. They are part of the collateral circulation that develops between the portal vein and vena cava in response to portal hypertension. They develop from the plexus of esophageal veins that drain into the azygos and hemiazygos veins. They receive blood from the left gastric vein and its esophageal branches and also from the short gastric veins via the splenic vein.
Heterologous expression of STIM1 p.R304W results in constitutive activation of the CRAC channel in vitro, and spontaneous bleeding accompanied by reduced numbers of thrombocytes in zebrafish embryos, recapitulating key aspects of Stormorken syndrome.

Red wale marks (longitudinal red streaks on varices)
Cherry-red spots (red, discrete, flat spots on varices)
Hematocystic spots (red, discrete, raised spots)
Esophageal varices are enlarged veins in the esophagus — usually the lower part of the esophagus. They're often due to obstructed blood flow through the portal vein, which carries blood from the intestine and spleen to the liver.

Incidence of PAI-1 deficiency: The incidence of PAI-1 deficiency is unknown. This is in part due to the lack of sensitive diagnostic assays and the rarity of the disease. A survey within the Federally Recognized Hemophilia Treatment Centers in the United States revealed few patients with documented PAI-1 deficiency. Another study compared 586 individuals known to have a bleeding tendency with 200 controls and found that 23% of the individuals with a bleeding tendency had low PAI-1 activity as compared with 10-13% of controls When 66 blood donors were evaluated, 14.6% of the females and 21% of the males had a PAI-1 activity As the number of case reports of PAI-1 deficiency are small, true incidence and prevalence cannot be determined.

Hereditary plasminogen activator inhibitor-1 (PAI-1)deficiency is considered an extremely rare disorder characterizedby hyperfibrinolysis due to decreased PAI-1 activity that resultsin frequent bleeding episodes. Five variants of PAI-1 polymorphismshave been identified: two common polymorphisms −765 4G/5G and −844A>G in the promoter; and three less common, Ala15Thr, Val17Ileat the signal peptide and Asn195Ile (). To date, only two types of mutationsare clearly associated with PAI-1 deficiency. One is the Ala15Thrmutation (), and the second isthe frame-shift mutation in exon 4 of the PAI-1 gene, which resultsin complete PAI-1 deficiency ().In this study, we present the case of a woman with PAI-1 functionaldeficiency having a heterozygous Ala15Thr mutation.

History of PAI-1 deficiency: The first published link between an altered PAI-activity associated with a hemorrhagic tendency was reported in 1989. The report documented a lifelong history of severe bleeding following surgery or trauma and evidence of hyperfibrinolysis in an elderly man. Upon analysis, it was demonstrated that his PAI-1 antigen levels were normal with reduced PAI-1 activity, likely representing a qualitative defect. Additional cases of qualitative PAI-1 deficiency have subsequently been identified.,

The first quantitative PAI-1 defect was described in 1991 and detailed a 36 year old female with lifelong epistaxis and a history of bleeding after minor surgery. She had no detectable PAI-1 antigen or activity. The first genetic defect linking a bleeding diathesis to a homozygous PAI-1 mutation was reported in 1992. Since that time, two other specific genetic mutations have been identified that are associated with the bleeding disorder,, (Please refer to the ‘’ section for more detailed information).

First we try to perform rubber bands ligation but Although the exact site of bleeding was identified, with the ligating apparatus it was more difficult to identify the bleeding, because this one darkens the visibility so sclerotherapy was used.
Therapeutic aims in acute variceal bleeding The important point is to treat the patient and not just the source of bleeding. The specific aims are:
Correct hypovolaemia; Stop bleeding as soon as possible; Prevent early rebleeding; Prevent complication associated with bleeding; Prevent deterioration in liver function.
