Summary
Hepatic infarction, a rare but fatal complication of interventional procedures, occurred in 0.5% of cases. Emergency embolization for hemorrhagic shock was a frequent cause.
Area of Science:
- Interventional Radiology
- Hepatology
- Vascular Surgery
Background:
- Hepatic infarction is a serious complication following interventional procedures.
- Understanding its incidence and risk factors is crucial for patient safety.
Purpose of the Study:
- To determine the incidence, background, and progression of hepatic infarction after interventional procedures.
- To identify risk factors and outcomes associated with post-interventional hepatic infarction.
Main Methods:
- Retrospective review of 1982 abdominal angiography and interventional procedures.
- Analysis of clinical records and abdominal CT scans for hepatic infarction.
- Identification of nine cases of hepatic infarction over a decade.
Main Results:
- Nine episodes (0.5%) of hepatic infarction were identified in 8 patients.
- Commonly associated with emergency embolization for postoperative bleeding and hemorrhagic shock.
- Hepatic arterial occlusion and portal venous flow abnormalities were observed.
- Impaired baseline liver function correlated with mortality, not CT findings.
Conclusions:
- Hepatic infarction following interventional procedures is rare but can be fatal.
- Emergency embolization in hemorrhagic shock is a significant risk factor.
- Multiple risk factors, including arterial insufficiency, contribute to its occurrence.
