Key result
Maxillofacial oncologic surgery carries a 0.14% VTE incidence, linked to lower extremity deep venous cannulas.
Why the study?
Venous thromboembolism is a leading cause of death in cancer patients, and risk factors in oral and maxillofacial oncologic surgery are not well defined.
What are the clinical characteristics and potential risk factors for VTE in patients undergoing oral and maxillofacial oncological surgery?
Observational (n=9,724)

What are the clinical characteristics and potential risk factors for VTE in patients undergoing oral and maxillofacial oncological surgery?
Lower extremity deep venous cannulation during prolonged oral and maxillofacial oncologic surgery may be a significant risk factor for perioperative VTE.
May support preferring upper extremity access in oral oncologic surgery; leaves open prospective confirmation before practice change.
BACKGROUND: Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) is a leading cause of death in cancer patients. The aim of this study was to explore the potential risk factor of VTE in oral and maxillofacial oncological surgery. MATERIAL AND METHODS: The data of patients who received operation in our institution were gathered in this retrospective study. A diagnosis of VTE was screened and confirmed by computer tomography angiography (CTA) of pulmonary artery or ultrasonography examination of lower extremity. Medical history and all perioperative details were analyzed. RESULTS: 14 patients were diagnosed as VTE, including 6 cases of PE, 7 cases of DVT, 1case of DVT and PE. The mean age of these patients was 62.07 years. Reconstruction was performed in 12 patients of these cases, most of which were diagnosed as malignance. Mean length of surgery was 8.74 hours, and lower extremity deep venous cannula (DVC) was performed in all these patients. CONCLUSIONS: We analyzed several characters of oral and maxillofacial surgery and suggested pay attention to lower extremity DVC which had a high correlation with DVT according to our data.

Wang et al. (2016) conducted an observational in Oral and maxillofacial tumors (n=9,724). Oral and maxillofacial oncologic surgery and lower extremity deep venous cannula was evaluated on Incidence of venous thromboembolism (VTE). Among 9,724 patients undergoing oral and maxillofacial oncologic surgery, the overall incidence of venous thromboembolism was 0.14%, with lower extremity deep venous cannula identified as a potential risk factor.
