Clinical Analysis Of Interventional Therapy For Cockett Syndrome Complicated With Deep Vein Thrombosis Of Lower Extremities

Objective:To observe the clinical efficacy of endovascular treatment in patients with Cockett syndrome combined with deep vein thrombosis of lower extremities,evaluate its safety,and explore its comprehensive treatment plan.Methods:We retrospectively analyzed the clinical data of 39 patients with Cockett syndrome and deep vein thrombosis of the lower extremities admitted to the Department of Vascular Surgery of the First Affiliated Hospital of Chongqing Medical University from July 2019 to March2020,observe the changes in the circumference of the Lower limbs,the improvement of clinical symptoms,and the removal of thrombus before and after the patients receive intracavitary treatment,follow-up stent patency,venous patency,and PTS incidence,and finally evaluate the clinical efficacy.Results : The postoperative follow-up was 6-16 months.After treatment,the symptoms of lower limb swelling and pain were significantly relieved in all patients,and no serious bleeding complications occurred during thrombolysis;The circumference difference between the affected limb and the healthy limb before and after treatment: The thigh 15 cm above the knee is(8.15±3.31)cm before surgery and(1.17±0.77)cm after surgery,the difference was statistically significant(P<0.05).10 cm below the knee is(6.45±2.43)cm before surgery and(1.59±1.85)cm after surgery,the difference was statistically significant(P<0.05);The overall patency rate of the stent was 100%(24/24)at 6 and 9 months after the operation,the patency rate of the lower limb vein was(81.31±16.09)%,(80.21+17.06)%,and the incidence of PTS was 5.13%、17.95%;the clinical efficacy was evaluated 9 months after the operation,the cure was 20.51%,and the improvement was 79.49%.Conclusion : Intracavitary comprehensive treatment is safe and reliable,with high short and medium-term postoperative venous patency rates and high stent patency rates,which can effectively relieve clinical symptoms and reduce the incidence of PTS.The overall effect is significant.It is recommended as the first choice of treatment.
