Objective: To assess associated factors for the effectiveness of partial (PS) and total (TS) saphenectomy performed in patients from the Luis Arias-Schereiber Central Military Hospital (CMH) during 2017. Materials and methods: This is a cross-sectional study. Clinical records from CMH patients who underwent surgery because of peripheral venous insufficiency from January to December 2017 were reviewed. The following variables were assessed: age, gender, comorbidities (type 2 diabetes, high blood pressure, and obesity), time with the disease (in years), surgical location, operative time, occurrence of complications (hematoma, operative site infection, and saphenous nerve lesion), days of hospital stay, and declared clinical improvement. Associations amongst these variables and the type of performed saphenectomy (PS or TS) were sought for by using the Chi-square test, Fisher’s exact test, prevalence rates (PR), and the Mann-Whitney U test. Also, factor associated to a lesion in the saphenous nerve were assessed in the TS group using logistic regression. Results: One-hundred and seven clinical records were reviewed, 43 persons underwent PS (40.2%) and 64 underwent TS (59.8%), their mean age was 58 years, and nearly two-thirds of all patients were male (64.5%). There were no significant differences with respect to presurgical clinical and epidemiological characteristics and the type of surgical procedure performed. There were low rates of postoperative complications (PR (95% CI): 0.06 (0.01- 0.22)), saphenous nerve lesions (PR (95% CI): 0.02 (0.00-0.19)), and days hospitalized (p<0.05) in patients who underwent PS. Conclusion: Patients who underwent PS had better postoperative outcomes (frequency of postoperative complications, saphenous nerve lesions and hospitalization days) compared to those who had undergone TS. Future studies should assess the variables that might lead to these outcomes.
