Priapism is caused by an imbalance between penile blood inflow and outflow. There are two types of priapism: low-flow priapism due to venous occlusion and high-flow priapism due to uncontrolled arterial flow to the veins. High-flow priapism most frequently occurs as a result of penile trauma in which the intercavernosal artery disruption causes an arteriocavernosal fistula. It is rarely encountered in the pediatric and prepubertal population. Clinically, it manifests as a painless, prolonged erection after perineal trauma. Treatment ranges from expectant management to open surgical exploration with vessel ligation. We report the successful treatment of high-flow priapism in a 12-year-old prepubertal boy with superselective embolization.
阴茎异常勃起是由阴茎血液流入和流出之间的不平衡引起的。阴茎异常勃起有两种类型：因静脉闭塞导致的低流量阴茎异常勃起和因静脉动脉血流不受控制导致的高流量阴茎异常勃起。高流量阴茎异常勃起最常见于阴茎创伤后，其中海绵体间动脉破裂导致动静脉瘘。在儿科和青春期前人群中很少见。临床上，它表现为会阴创伤后无痛性、持续性勃起。治疗方法从观察处理到开放性手术探查并结扎血管不等。我们报告了一例12岁青春期前男孩通过超选择性栓塞成功治疗高流量阴茎异常勃起的病例。
