Transcatheter Arterial Micro-Embolization (TAME) Using Nexsphere-F in Patients With Chronic Pain in Elbow or Wrist

A Single-arm, Single-center, Open-label, Pilot Clinical Study to Evaluate the Efficacy and Safety of Transcatheter Arterial Micro-Embolization (TAME) Using Nexsphere-F in Patients With Chronic Pain in Elbow or Wrist

In patients with chronic elbow or wrist pain, the pain is controlled by conventional conservative therapy The pain reduction effect of Nexsphere-F embolization in patients who need additional treatment It is intended to demonstrate safety.

This clinical trial is a single cancer, single center, open label, and pilot clinical trial that demonstrates the performance and safety of Nexsphere-F for patients aged 19 to 80 who need additional treatment because their pain is not controlled even after taking existing treatments.

In addition, through this clinical trial, complications of embolization and Nexsphere-F and It checks the safety of side effects. Therefore, in this study, TAME treatment for patients with chronic elbow pain 2 to 7 months, 1 month later, 3 months, 6 wah VAS score reductions and QuickDASH scores, PRTEE score primary 6 Evaluate the reduction rate of medication, discontinuation rate of combination therapy, and occurrence of abnormal cases during the follow-up period. For patients with chronic wrist pain, VAS score after 2 to 7 days, 1 month, 3 months, and 6 months of TAME treatment QuickDASH score reduction rate, drug reduction rate after 6 months, discontinuation rate of combination therapy, and follow-up period the investigators will evaluate the effectiveness and safety of Nexsphere-F by evaluating whether abnormal cases occur during the period.
