Transjugular intrahepatic portosystemic stent shunt placement and embolization for hemorrhage associated with rupture of anorectal varices

Combination of Percutaneous Transhepatic Balloon-Assisted Transjugular Intrahepatic Collateral Caval Shunt and Embolization for Successful Hemostasis of Lower Gastrointestinal Bleeding Associated With Extremely Enlarged Anorectal Varicose Veins

Ectopic varices may frequently occur in the rectum in the context of portal hypertension. Although rectal variceal bleeding is not a frequent bleeding situation, it can be life-threatening unless diagnosed and treated immediately. However, there is no specific treatment strategy established so far. We report a case of a man with extrahepatic portal hypertension and severe hematochezia due to rectal variceal bleeding. The patient was diagnosed in the past with portal vein thrombosis, in the context of myelodysplastic syndrome/myeloproliferative neoplasm overlap syndrome, with ectopic varices in the small intestine, colon, rectum and anal canal, peritoneum and perisplenic veins, treated with mesorenal shunt placement and an oral beta-blocker. After the initial stabilization with fluid replacement and red blood cell transfusion, he underwent endoscopic injection sclerotherapy, with no effect on bleeding episodes, while the large size of the varices precluded the option of endoscopic band ligation. Due to the presence of large collateral veins next to the inferior vena cava, the patient underwent combination therapy with Percutaneous Transhepatic Balloon-Assisted Transjugular Intrahepatic Collateral Caval shunt placement, to decompress portal pressure, followed by angiographic embolization of the feeding vessels resulting in successful hemostasis. Hematochezia ceased, hemoglobin was stabilized and the patient was safely discharged from the hospital. Controlling and treating rectal varices can be a challenging task indicating the need of a multidisciplinary approach. In the absence of well-established treatment guidelines for rectal varices, we highly recommend treatment of refractory ectopic variceal bleeding, non-responsive to endoscopic treatments, with portocaval shunt placement in combination with embolization.

Endoscopic treatment of esophagogastric variceal bleeding with rectal variceal bleeding: Report of two cases

BACKGROUND

Esophagogastric variceal bleeding is one of the most common and serious complications of portal hypertension in patients with decompensated cirrhosis. However, esophagogastric variceal bleeding with rectal variceal bleeding is clinically rare. If not treated timely or properly, it will cause fatal consequences.

CASE SUMMARY

This paper reports two cases of esophagogastric variceal bleeding complicated with rectal varices bleeding. The bleeding was stopped successfully using endoscopic sclerotherapy and ligation method on the basis of drug treatment.

CONCLUSION

Clinicians should broaden their thinking and consider the occurrence of such a situation during the treatment of gastrointestinal bleeding.

Treating Untreatable Rectal Varices

Background

Rectal varices are portosystemic collaterals that arise as a complication of portal hypertension. Despite their significant prevalence among cirrhotic patients, clinically important bleeding occurs only in a minority. Various treatment options are available, with endoscopic therapies being widely used, and both interventional radiology and surgery being considered for refractory bleeding rectal varices.

Case

We report the case of a 61-year-old male with hepatic cirrhosis and bleedingrectal varices refractory to endoscopic therapy, successfully managed with a combination of transjugular intrahepatic portosystemic shunt (TIPS) and selective variceal embolization.

Conclusions

Radiological techniques are effective options for refractory bleeding. Adding embolization to TIPS implantation could represent a valid adjunctive measure for haemostasis of recurrent rectal variceal bleeding.
