Agenesis of the inferior vena cava (IVC) is a rare congenital anomaly that is associated with the development of extensive collateral circulation with the aim of compensating for the inadequate return of blood to the right ventricle. This collateral circulation predisposes to the emergence of venous hypertension with stasis and thrombus formation. Most cases are asymptomatic and are diagnosed incidentally. We report the case of a 28-year-old man who presented with bilateral deep vein thrombosis (DVT) as the first manifestation of agenesis of the IVC. We decided to maintain anticoagulation for an indefinite period of time after a multidisciplinary discussion. IVC agenesis should be considered a cause of DVT in young men, with bilateral and proximal thrombosis and without other risk factors. The rarity of the condition makes its therapeutic approach complex.
下腔静脉发育不全是一种罕见的先天性异常,与广泛的侧支循环形成有关,目的是补偿回流入右心室的血液不足。这种侧支循环易导致静脉高压伴血流淤滞和血栓形成。大多数病例无症状,是偶然诊断出来的。我们报告一例28岁男性,其首发表现为双侧深静脉血栓形成,为下腔静脉发育不全。经过多学科讨论后,我们决定无限期维持抗凝治疗。对于年轻男性出现双侧及近端血栓形成且无其他危险因素的深静脉血栓形成,应考虑下腔静脉发育不全为病因。该疾病的罕见性使其治疗方法较为复杂。
