Objective To investigate the effect of warming needle moxibustion combined with traditional Chinese medicine Hot Election Bag intervention on the risk of postoperative lower extremity deep venous thrombosis（LEDVT） in patients with greater saphenous vein varicosity（GSVV）. Methods A total of 93 patients with GSVV admitted to a hospital in Nanyang from December 2019 to December 2020 were selected as the subjects. All patients received high ligation and stripping for GSVV and were assigned to the control group（n=46） and the observation group（n=47） according to different postoperative nursing intervention regimens. The patients in the control group received routine western medicine nursing intervention

and the patients in the observation group warming needle moxibustion in combination with traditional Chinese medicine Hot Election Bag intervention in addition to the routine nursing. Patients in both groups received consecutive interventions for 2 weeks. The rehabilitation of patients in the two groups was compared. The prothrombin time（PT）

activated partial thromboplastin time（APTT）

thrombin time（TT）

and fibrinogen（FIB） levels before and after the intervention were compared between the two groups. The mean blood flow velocity

maximum blood flow velocity

and lumen diameter of common femoral vein of lower limbs before and after intervention were compared between the two groups. The incidence of LEDVT was compared between the two groups. Results The disappearance time of subcutaneous hematoma

ulcer surface and lower leg numbness in the observation group were significantly different from those in the control group（P<0.05）. After the intervention

PT and APTT in both groups were longer than those before the intervention

and the observation group was longer than the control group

and the differences were statistically significant（P<0.05）. After the intervention

TT in both groups was shorter than those before the intervention

with the observation group shorter than the control group

and the differences were statistically significant（P<0.05）. After the intervention

FIB levels in both groups were lower than those before the intervention

with the observation group lower than the control group

and the differences were statistically significant（P<0.05）. After the intervention

the mean blood flow velocity and maximum blood flow velocity of the common femoral vein in the two groups were higher than those before the intervention

with the observation group higher than the control group

and the differences were statistically significant（P<0.05）. After the intervention

the diameter of the common femoral vein of lower limbs in the two groups was smaller than that before the intervention

with the observation group smaller than the control group

and the differences were statistically significant（P<0.05）. The incidence rate of LEDVT in the observation group during the intervention was 8.51%

which was lower than that in the control group（30.43%）

and the difference was statistically significant（P<0.05）. Conclusion Warming needle moxibustion in combination with traditional Chinese medicine Hot Election Bag plays an effective role in the postoperative rehabilitation of patients with GSVV. It can improve the coagulation parameters and blood flow level and reduce the risk of LEDVT. These advantages justify a wider application of this procedure in clinical practice.
