Varicose vein embolization and portal vein stenting in a patient with sinistral portal hypertension-induced gastrointestinal hemorrhage: a case report.

INTRODUCTION AND IMPORTANCE

Massive gastrointestinal hemorrhage is a severe hemorrhage that occurs in the gastrointestinal tract and is a life-threatening condition. Sinistral portal hypertension is a common etiology for massive gastrointestinal hemorrhage, whose occurrence might be derived from pathological changes induced by obstruction and/or increased blood flow to the portal vein system. However, there is a rare study reporting pancreatic disease-induced sinistral portal hypertension.

CASE PRESENTATION

An 80-year-old female pancreatic cancer patient was admitted to our hospital on 22 January 2022 due to a massive gastrointestinal hemorrhage with shock after receiving radio-chemotherapy. Abdominal enhanced computerized tomography showed that the patient presented with pancreatic cancer-causing sinistral portal hypertension with massive collateral circulation, intrahepatic bile duct dilation, and the formation of massive ascites. Subsequent portography interventional procedure revealed the esophageal and gastric varix. Then, the varicose vein was embolized, and the stent was implanted at the lumen of the superior mesenteric vein accessing the portal vein. The patient recovered from pancreatic cancer-causing sinistral portal hypertension, and a normal direction of blood flow was observed in the superior mesenteric vein with a decreasing amount of ascites. In addition, a transfusion was also carried out, and the massive gastrointestinal hemorrhage was alleviated.

CLINICAL DISCUSSION AND CONCLUSION

This study emphasizes the successful treatment of massive gastrointestinal hemorrhage induced by pancreatic cancer-causing sinistral portal hypertension by varicose vein embolization and portal vein stenting, which could be considered an alternative opinion for these patients.
