Lower Limb Varicose Vein or Swelling Secondary to Cockett Syndrome / 中国微创外科杂志

Objective To explore the treatment method and curative effect for lower limb varicose vein or swelling secondary to Cockett syndrome. Methods From March 2014 to March 2015,a total of 25 cases of lower limb varicose vein (22 cases)or swelling (3 cases)secondary to Cockett syndrome were treated with percutaneous transluminal angiography (PTA).Stents were placed in the veins in 19 cases,and 22 patients with varicose veins were treated with the great saphenous vein high ligation and point type stripping at secondary stage. Results The operations were successful.The iliac vein PTA was performed in all the 25 patients.The iliac vein stent implantation was performed in 17 cases of varicose veins and 2 cases of lower limb swelling.The saphenous vein high ligation and point type stripping was performed in 22 cases of varicose veins of lower extremity at 1 month after the interventional treatment.Postoperatively,no complications such as lower limb swelling,infection,or deep vein thrombosis occurred.Follow-up at the first postoperative month showed 20 cases of cured and 5 cases of alleviated.Follow-up for 3 -15 months (mean,12.4 months)in the 25 cases showed no lower limb swelling,recurrence of varicose vein,or deep vein thrombosis. Conclusions Cockett syndrome patients can be treated with iliac vein PTA.Whether or not a stent placement is required is determined according to the extent of vein stenosis.Postoperatively,lower limb swelling can be significantly alleviated.For patients with secondary varicose vein of lower extremity,saphenous vein ligation and point type stripping is recommended after 1 month.

Risk factors leading to pulmonary embolism in patients of lower extremity deep vein thrombosis with iliac vein compression / 中华普通外科杂志

Objective To evaluate risks of symptomatic pulmonary embolism (PE) in deep vein thrombosis (DVT) patients complicating iliac vein compression syndrome (IVCS).Methods Between January 2010 and January 2015,patients diagnosed with lower extremity DVT and IVCS at our institution were included.The odds of symptomatic PE versus lower extremity DVT complicated with IVCS were assessed using Logistic regression models.Its association with age,gender,thrombophilic risk factors,degree of stenosis,filter implantation and symptomatic PE were assessed.Results Of 759 patients,410 patients had inferior vena cava (IVC) filters implanted and 349 had not.In filter placement group,3 patients suffered from symptomatic PE among 32 with thrombi intercepted in IVC filters.In the group with no IVC filters placement,39 cases suffered from symptomatic PE.Symptomatic PE was in positive correlation to respiratory disease and right lower extremity DVT,and negative correlation to IVC filter implantation.Conclusions In lower extremity DVT patients complicated with IVCS,the right lower extrenity DVT and respiratory disease are risk factors of symptomatic PE.IVC filter implantation prevents symptomatic PE from happening in most patients.
