Perioperative Ultrasound for Endothermal Ablation: Necessary or Superfluous?

Our standard protocol for endothermal venous ablation is to perform a perioperative ultrasound. This step affords our treatment team with a wealth of information: determine the appropriate site for percutaneous access, assess the presence of communicating pathologic perforators, and locate any communicating varicosities. However, the most significant indication for perioperative ultrasound is to assess whether new thrombus has developed in the axial vein to be treated. The purpose of our review was to determine how often new thrombus was demonstrated on perioperative ultrasound. Methods
