deep venous collateral angiography

Objective: To investigate the clinical significance of preoperative lower extremity venography in patients with varicose veins.Methods: From February 2019 to July 2023, 498 patients (583 diseased lower limbs) with lower limb varicose veins as the first symptom were selected and admitted to the Seventh People’s Hospital of Chongqing. Paracentesis of the deep veins of the lower extremities was performed in all affected limbs to observe the morphology of the deep veins from the ankle to the pelvis, the patency of the deep veins, and the reflux of contrast medium when the patients performed the Valsalva manoeuvre. The aetiology of varicose veins was analysed according to the imaging manifestations and individualised treatment plans were formulated according to the different aetiologies.Results: The imaging success rate of 583 diseased lower limbs was 100%, of which 285 (48.9%) were primary lower limb deep vein valve insufficiency, 186 (32%) were simple superficial varicose veins, 63 (10. 8%) were iliac vein compression syndromes, 41 (5%) were post-thrombotic syndromes of the deep veins of the lower limbs and the others (primary deep vein avascularity of the lower limbs, bifemoral venous malformations, congenital varicose vein osteohypertrophy syndrome, tumour compression, etc.) 8 articles (1.37%).Conclusion: The advantages of lower extremity deep vein bypass angiography are simple operation, low trauma, and high specificity, which can help to diagnose the aetiology of lower extremity varicose veins and guide the clinical treatment.
