radioablation (photodynamic ablation)

Introduction

Ablation of tissue with radiofrequency radiation.

Pathology

• results in coagulation necrosis

Indications

• tumor ablation for non-resectable cancers
• cardiac radioablation
  • ablation of cardiac conduction system anomalies
• volume reduction of tongue base for obstructive sleep apnea

Radiology

performed in association with imaging guidance

Complications

• cardiac radioablation may be complicated by pericardial tamponade
  • results from perforation of myocardium
  • bedside echocardiography confirms diagnosis
  • management includes pericardiocentesis

More general terms

• ablation; extirpation

More specific terms

• cardiac radioablation (photodynamic cardiac ablation)
• radioablation for obstructive sleep apnea
• radioablation of renal neoplasm
• radioablation, tongue
• radioactive iodine-131 (I-131) ablation
• radiofrequency catheter ablation
