Combined transhepatic and transsplenic recanalization of chronic splenic vein occlusion to treat left-sided portal hypertension: A cases report.

RATIONALE: This report describes a unique case of a combination transhepatic and transsplenic recanalization of chronic splenic vein occlusion to treat left-sided portal hypertension (LSPH).

PATIENT CONCERNS: In this case report, we report a 49-year-old male who was admitted due to LSPH causing black stools for 2 days and vomiting blood for 1 hour.

DIAGNOSES: The patient has a history of multiple episodes of pancreatitis in the past. After admission, abdominal contrast-enhanced CT scan showed the appearance of pancreatitis, with extensive splenic vein occlusion and accompanied by gastric varicose veins, indicating the formation of LSPH.

INTERVENTION: The patient received treatment with a combination of splenic and hepatic splenic venoplasty.

OUTCOMES: Follow up for 1 year, CT and gastroscopy showed disappearance of gastric varices.

LESSONS: Splenic venoplasty is an effective method for treating LSPH. When it is difficult to pass through the occluded segment of the splenic vein through a single approach, percutaneous double approach splenic venoplasty can be attempted for treatment.
