Summary
Portal vein thrombosis can occur after liver resection, particularly when the right portal vein branch is ligated during right hepatectomy. Hepatic angiography helps identify this complication and guide surgical decisions.
Area of Science:
- Hepatobiliary surgery
- Vascular surgery
- Diagnostic imaging
Background:
- Liver resection, a common surgical procedure, carries risks including vascular complications.
- Portal vein thrombosis (PVT) is an uncommon but serious complication following liver resection.
Observation:
- A case of PVT occurred after right hepatectomy due to ligation of the right portal vein branch.
- The patient presented with an atypical portal vein anatomy, lacking bifurcation.
Findings:
- Hepatic angiography is crucial for diagnosing PVT in this context.
- Angiography can visualize the specific abnormality caused by portal vein ligation.
Implications:
- Accurate diagnosis via hepatic angiography influences surgical management strategies.
- Understanding atypical venous anatomy is vital for preventing PVT during hepatectomy.
