Step 10. Post-Procedure Doppler Arterial Patency Confirmation

At the end of the procedure, again confirm that arterial patency is maintained to exclude inadvertent intra- or extra-arterial tamponade (Figure 5). Sudden onset of pain distally suggests this may have occurred. Remember that with increasing doses per site (0.5-1.0 mL), the risk of extra-arterial tamponade increases. In this circumstance, hyaluronidase should be administered immediately (eg, Hylenex or recombinant hyaluronidase) to dissolve the injectate, along with other supportive measures to ensure restoration and maintenance of arterial blood flow.

Step 11. Patient Follow-up and Expected Pain Relief

After the procedure, the patient should be contacted at 24 hours and 1 week to assess pain relief and the need for additional treatment. Expected pain relief should result in a VAS pain score of 0-4 out of 10, with a duration from 8 weeks to 4 months—and, in some cases, permanently—depending on the underlying pathology.
