Summary
Transcatheter arterial embolization (TAE) is effective for controlling postoperative hepatic artery hemorrhage. However, the presence of collateral arteries during TAE can impact patient outcomes.
Area of Science:
- Interventional Radiology
- Vascular Surgery
- Hepatology
Background:
- Postoperative hemorrhage following upper abdominal surgery presents a significant clinical challenge.
- Transcatheter arterial embolization (TAE) is an established endovascular technique for managing arterial bleeding.
Purpose of the Study:
- To evaluate the angiographic findings and clinical outcomes of transcatheter arterial embolization (TAE) for hepatic artery hemorrhage after upper abdominal surgery.
- To assess the effectiveness and safety of TAE in this patient population.
Main Methods:
- Retrospective analysis of ten patients (nine male, one female, mean age 63.5 years) who underwent emergency hepatic artery embolization.
- Review of angiographic findings, embolization procedures, and clinical results.
Main Results:
- Angiography revealed pseudoaneurysms (n=6) and extravasation (n=5). Bleeding originated from various hepatic and related arteries.
- TAE was successful in achieving hemostasis in eight patients. Two patients with unsuccessful TAE died from bleeding.
- Favorable clinical courses were observed in six patients where collateral arteries were visualized, avoiding hypoxic hepatic failure.
Conclusions:
- Transcatheter arterial embolization (TAE) is a valuable treatment modality for postoperative hepatic artery hemorrhage.
- The identification and management of collateral arteries during TAE are crucial for optimizing patient prognosis and preventing complications like hepatic failure.
