Summary
Embolotherapy is increasingly used for liver cancer management. This review covers neovascularization, embolic agents, and techniques like transarterial chemoembolization for treating hepatic malignancies.
Area of Science:
- Interventional Radiology
- Oncology
- Vascular Medicine
Background:
- Embolotherapy is a key treatment for primary and secondary liver cancers.
- Hepatic artery-based treatments are enabled by tumor neovascularization.
Purpose of the Study:
- To review the role of embolotherapy in managing hepatic malignancies.
- To discuss the principles of neovascularization in hepatic artery-based treatments.
- To provide an overview of embolic agents and therapeutic techniques.
Main Methods:
- Review of current literature on embolotherapy for hepatic malignancies.
- Discussion of the pathophysiology of neovascularization in liver tumors.
- Categorization of embolic agents into three generations.
- Description of techniques including bland embolization, transarterial chemoembolization, drug-eluting beads, and selective internal radiotherapy.
Main Results:
- Embolotherapy offers a range of options for liver cancer treatment.
- Understanding neovascularization is crucial for effective hepatic artery-based embolization.
- Various embolic agents and delivery systems have evolved.
- Different techniques carry specific risks and benefits.
Conclusions:
- Embolotherapy is a rapidly advancing field in interventional oncology.
- The choice of embolic agent and technique depends on tumor characteristics and patient factors.
- Further research is needed to optimize outcomes and minimize complications.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

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...
02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
