The inferior vena cava agenesis (IVCA) is a rare and often asymptomatic malformation due to the abundant development of the collateral circulation. However, it is frequently found in young people and carries a significant risk of deep venous thrombosis (DVT). It is estimated that about 5% of patients under 30 years of age presenting with DVT have this condition. We report a case of a previously healthy 23-year-old patient presenting with signs of acute abdomen and hydronephrosis due to the thrombophlebitis of an unusual iliocaval venous collateral, which developed secondary to IVCA. After treatment, the iliocaval collateral and hydronephrosis completely regressed on a 1-year follow-up. To our knowledge, this is the first such case reported in the literature.
下腔静脉发育不全（IVCA）是一种罕见的、通常无症状的畸形，因为侧支循环发育丰富。然而，它在年轻人中经常被发现，并且具有深静脉血栓形成（DVT）的重大风险。据估计，在30岁以下出现DVT的患者中，约5%患有这种疾病。我们报告一例23岁既往健康的患者，因IVCA继发的异常髂腔静脉侧支血栓性静脉炎，出现急性腹痛和肾积水症状。治疗后，在1年的随访中，髂腔侧支和肾积水完全消退。据我们所知，这是文献中报道的首例此类病例。
