Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Supermicrosurgical lymphaticovenous anastomosis (LVA) can be performed in different configuration such as end-to-end (LVEEA), end-to-side (LVESA), and side-to-end (LVSEA). Each configuration has its own advantages and disadvantages. However, it has remained ambiguous as to which anastomotic o configuration to choose. The aim of this study is to analyze and compare the relative sizes of lymphatic vessel (LV) and recipient vein (RV), in attempts to provide the basis for proper selections of the anastomotic configuration. From March 2016 to October 2018, 100 lymphedema patients with 103 lymphedematous lower limbs (stage I-III) were included. All patients underwent supermicrosurgical LVA. Demographic data and intraoperative findings, including the number and size of the LV/RV, the size discrepancies, and the numbers of LVA performed were recorded. The severity of LVs were classified based on the lymphosclerosis classification (s0, s1, s2, and s3). One-way ANOVA test and post hoc analysis with Bonferroni's correction were performed for size discrepancy analysis. A total 730 LVA were performed with 621 LVs and 468 RVs, averaging 7.1 LVA per limb. Of these, 367 (50.3%) were LVEEA, 333 (45.6%) were LVESA, and 30 (4.1%) were LVSEA. The average LV and RV size was 0.61 ± 0.35 mm and 0.87 ± 0.43 mm, respectively ( p < 0.001). The average LV size in different configuration: LVEEA = LVESA < LVSEA ( p < 0.001); The average RV size: LVEEA = LVSEA < LVESA ( p < 0.001); The size discrepancy: LVESA > LVSEA > LVEEA ( p < 0.001).The LVSEA group has more s1 lymphatic vessels as opposed to LVEEA and LVESA ( p = 0.004). The size and the comparative discrepancy between the LVs and RVs are the determining factors for proper anastomotic configuration selection during LVA. LVESA was more frequently performed when vessel size discrepancy was larger. The efficacy of each anastomotic configuration has yet to be determined.
