Background
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.
However,
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,
infarctions,
vascular thrombosis,
biliary lesions,
visceral ( abdominal or thoracic) lesions,
bowel or stomach injuries,
infections and others of unclear origin and less reported as massive tumor intrahepatic,
peritoneal or biliary seeding that may question the use of these techniques in certain cases.
Adequate choice of candidates by analyzing the number,
size and location of lesions are critical to decide the type of needle,
access route and ablative technique.
We analyze the major complications related to these procedures,
establishing action keys to avoid them as much as possible.
