Summary
Hepatic vein embolization, combined with portal vein embolization, can enhance future liver remnant hypertrophy before major liver surgery. A case report details managing an unintended glue cast migration during this procedure.
Area of Science:
- Interventional Radiology
- Hepatobiliary Surgery
- Vascular Embolization
Background:
- Major hepatectomy necessitates adequate future liver remnant (FLR) volume.
- Ipsilateral liver venous deprivation via hepatic vein embolization (HVE) alongside portal vein embolization (PVE) aims to maximize FLR hypertrophy.
- HVE is an emerging technique with potential complications.
Purpose of the Study:
- To present a case of HVE complicated by glue cast migration.
- To describe the endovascular management of glue cast embolization in the inferior vena cava (IVC).
- To discuss the role and risks of HVE in liver surgery preparation.
Main Methods:
- The study describes a case involving HVE combined with PVE prior to major hepatectomy.
- A glue cast used for hepatic venous occlusion migrated into the IVC.
- Endovascular retrieval of the misplaced glue cast was performed.
Main Results:
- The case highlights a rare complication of HVE: unintended migration of embolic material.
- Successful endovascular retrieval of the glue cast from the IVC was achieved.
- The management strategy for this specific complication is demonstrated.
Conclusions:
- HVE is a technique that can augment FLR hypertrophy but carries risks.
- Complications such as embolic material migration require prompt and effective endovascular management.
- Further understanding of HVE's role and safety profile is warranted in the context of major hepatectomy.

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

1.5K
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...
