Background:
Microsurgical techniques for the treatment of lymphedema rapidly increased in popularity. Although surgical success with vascularized lymph node (VLN) transfer has been demonstrated, limited studies have investigated the influence of microsurgical treatments on health-related quality-of-life (HRQoL) parameters. The aim of this study was to prospectively evaluate changes in HRQoL following VLN transfer for upper- and lower-extremity lymphedema using a validated instrument.
Methods:
An Institutional Review Board-approved prospective study was performed of patients who underwent VLN transfer for symptomatic upper- or lower-limb lymphedema. A validated lymphedema-specific questionnaire-lymphoedema quality-of-life study-was utilized to assess specific quality-of-life parameters at multiple time points during the 12-month perioperative period. For a comparison with HRQoL metrics, limb circumference measurements were obtained to assess circumference differentiation.
Results:
Twenty-five patients met the study criteria. Limb circumference analysis revealed significant early improvements following VLN transfer, with continued improvement during the study period (upper-limb lymphedema: 24.4 %; lower-limb lymphedema: 35.2 %). These improvements were mirrored by improvements in all HRQoL domains and overall quality of life (p < 0.01). The function, body appearance, symptom, and mood domains were all found to be significantly improved during the postoperative evaluation, with continued improvement being reported throughout the study period (p < 0.01 within each domain).
Conclusions:
Microsurgical treatment of lymphedema with VLN transfer procedures effectively decrease limb circumference. This improvement is mirrored by improvements in patient-reported outcomes and quality of life. These changes can be observed as soon as 1 month postoperatively, and continued steady improvement can be expected.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
01:15Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
