| Abstract: |
Lymphaticovenular anastomosis (LVA) using supermicrosurgical techniques is effective for treating and preventing progression of lymphedema. We analyzed the influence of pregnancy on LVA in five patients from a total 2179 LVA cases. Previous studies offer conflicting reports on whether pregnancy worsens pre-existing lymphedema. This is the first report on the influence of pregnancy on lower limb lymphedema previously treated by multisite LVA (mLVA). Five patients with primary (n=4) and secondary (n=1) lower leg lymphedema were analyzed for this study. Patient age ranged from 18 to 31 (average 22.6) years old with 4 right and 1 left extremities involved. Duration of symptoms ranged from one to 19 (average 7.4) years and the periods of compression therapy were from 1 to 19 years (6.6 years). Four patients had single pregnancies and one patient was multiparous with 3 pregnancies. Final follow-up ranged from 5.8 to 18 years (average 8.9 years) after the primary mLVA. All patients had normal pregnancy, birth, and no serious complications after surgeries. Following pregnancy three patients had complete functional recovery (limb volume reduction and no compression requirement), one with functional improvement (limb volume reduction but required compression), and one with no change in symptoms (not worse and continued need for compression). There were no occurrences of infection following pregnancy. Based on this case series, it is suggested that pregnancy does not worsen the pre-existing lymphedema in patients who had previously undergone mLVA. Further studies with larger number of patients are needed to confirm these results. Copyright by International Society of Lymphology. |
