Single Center Result Analysis Of Lower Extremity Deep Venography In Patients With Venous Variation

Objective: To analyze the classification and incidence rate ofvenous malformations through angiography and analyze the correlation with clinical symptoms and the guiding significance for clinical treatment.Methods: The images and medical records of 4420 patients（5982 affected limbs）who underwent Anterograde Venography of deep veins of lower limbs from June2012 to June 2021 were analyzed retrospectively,and the imaging results were classified and counted.It includes gender,age,first symptom,classification and incidence rate of venous malformations.Results: There were 4420 patients,2874 males,accounting for 65%;1546 women,accounting for 35%.Among the 5982 affected limbs,there were 3089 left lower limbs,2053 right lower limbs and 402 double lower limbs.The youngest is 32 years old,the oldest is 90 years old,and the average age is 62.5 years old.At present,297 cases of venous variation and 20 cases of inferior vena cava variation have been found,including 7 cases of double inferior vena cava variation（0.16% of the total number of patients）,11 cases of left inferior vena cava variation（0.25% of the total number of patients）,2 cases of inferior vena cava stenosis（0.04% of the total number of patients）,and 21 affected limbs of double iliac vein variation（0.35% of the total number of limbs）,There were 208 affected limbs with double superficial femoral vein variation（3.47%）,36 affected limbs with double great saphenous vein variation（0.60%）,and12 limbs with congenital varicose bone hypertrophy syndrome（0.20%）.Among them,8 cases of inferior vena cava variation,10 cases of iliac vein variation,39 cases of femoral vein variation,23 cases of great saphenous vein variation and 5 cases of KTS were found in the affected limbs with superficial varicose veins of the lower limbs as the first symptom;There were 4 cases of inferior vena cava,6 cases of iliac vein,50 cases of femoral vein,8 cases of great saphenous vein and 7 cases of KTS;There were 5 cases of inferior vena cava variation,1 case of iliac vein variation,39 cases of femoral vein variation and 2 cases of great saphenous vein variation;There were 2cases of iliac vein variation,39 cases of femoral vein variation and 2 cases of great saphenous vein variation;There were 3 cases of inferior vena cava variation,2 cases of iliac vein variation,41 cases of femoral vein variation and 1 case of great saphenous vein variationConclusion: The clinical symptoms of patients at the time of treatment were varicose veins and swelling of lower extremities,which should be examined by deep venography of lower extremities;Venography provides a reliable basis for the diagnosis and treatment of vascular variation;Understanding the correlation between venous variation and its clinical symptoms has guiding significance for clinical treatment and effectively reduces misdiagnosis and mistreatment.
