Insights
Hepatic veno-occlusive disease (HVOD) can be caused by Gynura segetum ingestion. Portal flow reversal on imaging is a key diagnostic sign, and liver transplantation is crucial for severe cases.
Area of Science:
- Hepatology
- Toxicology
- Radiology
Background:
- Hepatic veno-occlusive disease (HVOD), also known as hepatic sinusoidal obstruction syndrome (HSOS), is a severe liver condition.
- It involves damage to liver sinusoidal endothelial cells, leading to blocked hepatic venules and significant mortality.
- The condition can arise from various causes, including toxin exposure.
Observation:
- A case study of HVOD following one month of Gynura segetum ingestion is presented.
- The patient exhibited symptoms of abdominal pain and distension.
- Diagnosis was confirmed using CT and liver ultrasonography.
Findings:
- Portal flow reversal was identified as a characteristic imaging finding in this HVOD case.
- This finding is proposed as a specific diagnostic criterion for HVOD.
- The patient received best supportive care but ultimately succumbed to the disease.
Implications:
- Early recognition of portal flow reversal on imaging can aid in HVOD diagnosis.
- Prompt consideration of liver transplantation is vital for patients with worsening HVOD.
- Understanding toxicological causes like Gynura segetum is crucial for prevention.
Introduction:
Hepatic veno-occlusive disease (HVOD), as known as hepatic sinusoidal obstruction syndrome (HSOS), is an obliterative venulitis of the terminal hepatic venules, which is responsible for considerable mortality. The potential mechanism is destruction of hepatic sinusoidal endothelial cells (SEC), with sloughing and downstream occlusion of terminal hepatic venules. Here, we report a case of HVOD who have a history of ingestion of Gynura segetum for 1 month. The patient presents for abdominal pain and distension. He was diagnosed for HVOD using computerized tomography (CT) and ultrasonography of liver. And then best supportive care was added. However, without liver transplantation for financial reason, he died in 1 month after discharged from hospital.
Conclusions:
We think portal flow reversal was a characteristic imaging findings of HVOD, which can be listed as a specific diagnostic criterion of HVOD. Once the condition was worsening, liver transplantation should be considered as the first choice of treatment planning.

Hepatic Portal System
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...
