Deep vein thrombosis (DVT) is rare in pediatric patients. Congenital inferior vena cava (IVC) anomalies are asymptomatic; however, these can cause DVT in younger patients rarely.
In this case, a 14-year-old male patient was referred to our hospital for lower abdominal pain.
At the first hospital he visited, computed tomography revealed a thrombus in the veins of the abdomen and lower extremities; however, an accurate diagnosis could not be made because the thrombus was thought to be inconsistent with abdominal pain. Close examinations revealed swelling of the lower extremities and pain while walking. Contrast-enhanced computed tomography revealed the absence of IVC (AIVC), resulting in DVT at the external iliac, gonadal, inferior mesenteric, and collateral veins of the right pelvic cavity.
The patient received anticoagulation therapy.
At a follow-up 6 months later, his symptoms improved, and a thrombus was not found. AIVC could cause DVT.
DVT is rare in pediatric patients and is difficult to diagnose when the initial symptoms are vague. Conservative treatments are the most commonly used treatment; long-term follow-up is needed.
小儿深静脉血栓形成（DVT）较为罕见。先天性下腔静脉（IVC）异常通常无症状；然而，这些异常在年轻患者中极少会导致DVT。
在本病例中，一名14岁男性患者因下腹部疼痛被转诊至我院。
在他最初就诊的医院，计算机断层扫描显示腹部和下肢静脉有血栓形成；然而，由于认为该血栓与腹痛不符，无法做出准确诊断。进一步检查发现下肢肿胀且行走时疼痛。增强计算机断层扫描显示下腔静脉缺如（AIVC），导致右侧盆腔髂外静脉、性腺静脉、肠系膜下静脉及侧支静脉出现DVT。
患者接受了抗凝治疗。
6个月后的随访中，其症状有所改善，未发现血栓。AIVC可导致DVT。
小儿DVT罕见，初始症状不明确时难以诊断。保守治疗是最常用的治疗方法；需要长期随访。
