Abstract:
Objective:To compare the application effects and comfort of three downstream thrombolysis through superficial dorsal pedal veins in the treatment of deep venous thrombosis (DVT) of lower extremity.Methods:From January 2014 to October 2018, data of 120 patients with DVT who treated in Nanjing First Hospital of Nanjing Medical University were retrospectively analyzed. They were divided into the non-intervention group (the control group) , silicone tourniquet group (the experimental group I) and limb pressure band group (the experimental groupⅡ) , with 40 cases in every group. The daily thrombolytic drugs were the same in the three groups. No other intervention was carried out in the control group. In the experimental groupⅠ, a tourniquet was ligated 15 cm above the osseous mark of the medial malleolus of the affected limbs, the superficial vein blood flow was completely blocked by the lower limb venography, and the blood flow in the deep vein was fully developed. In the experimental group Ⅱ, limb pressure bands were used 15 cm above the osseous mark of the medial malleolus of the affected limb, DSA angiography was used to determine the optimal airbag inflation pressure value when the superficial vein was completely blocked, and the deep vein was fully developed. For the two experimental groups, ligation (tourniquet) or inflation (limb pressure band) at the same site was performed for 15 min, and relaxation time was 15 min, alternately without interruption. The detumescence rate of affected limb, clearance rate of thrombosis and comfort of affected limb were compared among the 3 groups.Results:In experimental group Ⅱ, the detumescence rate of affected limb was (83.40±8.91) % and the venous patency was (86.25±20.61) %, which were better than those of the control group and the experimental group I, and the differences were statistically significant ( F=3.767, 4.675; P<0.05) . 10 days after treatment, the clearance rate of thrombosis of the experimental groupⅡ, the control group and the experimental group I were respectively (96.50±2.78) %, (83.38±3.77) % and (87.13±2.71) %. The differences among the three groups were statistically significant ( F=13.019, P<0.01) . The limb comfort of the experimental groupⅡ was 87.5% (35/40) , and that of the experimental group I was 20.0% (8/40) , and the difference was statistically significant (χ 2=36.656, P<0.01) . Conclusions:In the downstream thrombolytic treatment of lower limb DVT through dorsal pedal veins, the use of a timed, constant pressure limb pressure band to block the superficial vein blood flow can achieve better thrombolytic curative effects and higher comfort degree of patients
