Insights
Interventional therapy effectively treats acute hepatic artery occlusion after liver transplantation. Angiography is crucial for diagnosing these complications, ensuring graft patency and avoiding re-transplantation.
Area of Science:
- Vascular Surgery
- Transplant Surgery
- Interventional Radiology
Background:
- Interventional treatment is increasingly used for hepatic artery occlusion.
- Acute hepatic artery occlusion is a significant complication following liver transplantation.
Purpose of the Study:
- To evaluate the diagnostic and therapeutic role of interventional methods for acute hepatic artery occlusion post-liver transplantation.
Main Methods:
- Retrospective analysis of 9 cases with acute hepatic artery occlusion after liver transplantation.
- Diagnosis confirmed by angiography and Doppler ultrasound.
- Interventional treatments included transcatheter thrombolysis and hepatic artery stent placement.
Main Results:
- Angiography diagnosed 9 cases; Doppler ultrasound identified 7.
- Transcatheter thrombolysis restored partial or total patency in 6 cases.
- Hepatic artery stent placement in 5 cases resulted in maintained patency, avoiding re-transplantation.
Conclusions:
- Angiography is vital for diagnosing hepatic artery complications post-liver transplantation.
- Interventional therapy offers a valuable treatment for acute hepatic artery occlusion, preserving liver allografts.
Background:
With the development of the associated technology, interventional treatment has become an important method for the treatment of hepatic artery occlusion in some countries. This study was undertaken to evaluate the role of interventional methods in the diagnosis and treatment of acute hepatic artery occlusion after liver transplantation.
Methods:
The diagnosis and treatment of 9 cases of acute hepatic artery occlusion after liver transplantation were retrospectively analyzed.
Results:
In 109 cases of liver transplantation, 9 were diagnosed by angiography. Among them, 7 were diagnosed by Doppler ultrasound. After transcatheter thrombolysis, the hepatic arteries were partially or totally patent again in 6 cases of hepatic artery occlusion after liver transplantation, and stent placements in the hepatic artery were performed in 5 cases. All stents proved patent and no patient required another liver transplantation.
Conclusions:
Angiography plays an important role in diagnosing hepatic artery complications after liver transplantation. Interventional therapy is a valuable method in the treatment of acute hepatic artery occlusion after liver transplantation.
