To review the main complications in the percutaneous thermoablative treatment of liver tumors. Establish action keys to avoid them and decrease morbidity and mortality.
Thermoablative percutaneous radiofrecuency and microwaves (RF and MW) treatments are accepted as safe therapeutic methods with complete response rates very similar to surgery in lesions <2 cm.
its use is generalized in lesions of increasing size,
which leads to increasingly demanding procedures that are not risk-free. We analyzed the main complications,
especially when performing large hepatic ablations (hemorrhages,
Findings and procedure details
Liver Ablation The liver has been the most common target organ for ablative percutaneous treatment of both primary and secondary neoplasms.
The ablation of hepatic lesions from the beginning has been considered very safe with very low mortality rates and major complications; oscillating generally from 0.7 to 1.4%.
Some recent series says a slightly higher mortality rates of up to 2% (Wong et.
Causes of death includes bowel perforation,
portal vein thrombosis,
Percutaneous ablative treatments of liver lesions are increasingly used in larger lesions.
Secondary complications in large ablations are also more frequent.
Their knowledge allows us to avoid them by increasing the safety of the procedures.
