Computed Tomography as an Objective Measurement Tool for Secondary Lymphedema Treated With Extracorporeal Shock Wave Therapy

Two patients with stage three secondary lymphedema of the upper extremities underwent treatment for breast cancer, including surgery, chemotherapy, and radiotherapy. They were examined with computed tomography (CT) before and after extracorporeal shock wave therapy (ESWT). We used a manual tracing method using PiViewSTAR software to calculate the volume of the upper extremities. There was a decrease in the volume of the subcutaneous compartment measured by CT before and after ESWT. CT may be helpful in determining the treatment target area of ESWT and to monitor the effect of treatment by measuring the changes in volume before and after ESWT in patients with lymphedema. Therefore, CT may have good clinical potential for treatment and follow-up in the management of lymphedema.
