摘要
ABSTRACT BACKGROUND Agenesis of the inferior vena cava (IVC) is an extremely rare congenital malformation. Although IVC dysplasia can present with symptoms, because of the low prevalence of this disease, it is often omitted from routine examination. Most reports on this topic have described the absence of the IVC; the absence of both a deep venous system and the IVC is even rarer. Chronic venous hypertension and varicosities leading to venous ulcers have been reported in patients with absent IVC that could be surgically bypassed; however, the absence of iliofemoral veins precluded any bypass procedure in the present patient. CASE PRESENTATION The authors report a case of IVC below renal vein hypoplasia in a 5-year-old girl who presented bilaterally with venous stasis dermatitis and ulcers in the lower extremity limb area. Ultrasonography revealed no clear IVC and iliofemoral venous system under the renal venous plane. Magnetic resonance venography subsequently confirmed the same findings. The patient’s ulcers were healed by compression therapy and routine wound care. CONCLUSIONS This is a rare case of venous ulcer in a pediatric patient stemming from congenital IVC malformation. With this case, the authors demonstrate the etiology of the appearance of venous ulcers in children.
