Abstract

Venous thromboembolism (VTE) is a significant complication in patients after undergoing major surgery. The type of surgery is believed correlated with the incidence of VTE. This study aimed to evaluate the correlation between type of surgery and incidence of VTE among patients who underwent major surgery. It was a retrospective study conducted in Dr. Sardjito General Hospital, Yogyakarta using medical record data of patients who underwent major surgery and were diagnosed with VTE between 2016 and 2020. Patients were grouped by surgery type, and length of stay (LoS). All caused deaths were also analyzed. Among 29,120 patients who underwent major surgery, 76 (0.26%) experienced VTE with females patients accounting for 75%. The mean age of the patients was 55 yr. All VTE cases had the mean LoS of 25 d. The highest proportion of patients who experienced VTE were patients who underwent tumor removal (67.0%) followed by trauma patients (18.4%). A significant difference in the incidence of mortality between the surgical groups was reported (p = 0.02). Post-cardiology had the highest risk of mortality (OR=7.46; 95% CI: 0.322 - 172.61) while age had the lowest risk of mortality (OR=1.01; 95% CI: 0.953 - 1.071). In conclusion, surgery type is correlated with the incidence of VTE. Surgery due to cancer and trauma has a higher risk of VTE compared to the others.

Abstract

Venous thromboembolism (VTE) is a significant risk, especially for older individuals. Indonesian studies found 37.1% VTE incidence in bedridden patients over 40 and 2.1% in major surgeries. Surgery, like hip fractures, raises the risk temporarily. Diagnosis relies on tests like ultrasound with Doppler, Wells score, and neutrophil-to-lymphocyte ratio (NLR). This study aimed to evaluate the laboratory findings of postoperative VTE. A retrospective analysis was conducted in Dr. Sardjito General Hospital, Yogyakarta using medical record data of VTE patients who underwent major surgery. The laboratory data, including complete blood count characteristics for every month for three months after postsurgery and DVT presentation when it occurred on the diagnostic day were collected. In total of 27 patients involved in this study, VTE cases were more common in digestive (41.2%) and obstetric gynecology surgeries (29.4%) for females, and nervous (44.4%) and cardiovascular surgeries (22.2%) for males. Females had a higher prevalence of Well Score ≥3 (82.4% vs 40%; p=0.058) and longer VTE therapy durations (65.50 ± 46.51 vs 39.60 ± 41.04 d; p=0.172). Males had more unilateral VTE occurrences (90.9 vs 56.3%; p=0.070) and a higher proportion of total occlusion cases (60 vs 37.5%; p=0.422). NLR exhibited a significant decrease from the 1st to the 2nd month (10.52 vs 3.64; p=0.009), followed by an insignificant increase in the 3rd month (3.64 vs 3.98; p=0.878). Notably, NLR trended downward in the 2nd month examination. In conclusion, VTE occurs in 0.21% of postoperative patients, with the highest incidence observed in post-gynecological surgery patients. The NLR can serve as a diagnostic tool for VTE in extremities, as an elevated NLR indicates the presence of a more proximal thrombus.
