外伤致真假性动脉瘤在临床上较少见,病因多为外伤所致动脉血管壁的破裂或损伤。现将我们所见并经手术证实的真、假性动脉瘤报告如下。例1 男性,26岁。从2.5米高处坠落,摔伤下肢,行左股骨干骨折切开复位,髓内针固定术。术后大腿仍肿胀,造影示股深动脉远端周围椭圆形浓染色。呈囊状改变,内造影剂密度不均匀,边界清,周围可见渗出性改变。后术见股骨干内侧有一包块状瘤 Trauma caused by true and false aneurysms are less common in clinical practice, mostly due to trauma caused by arterial wall rupture or injury. Now we see and surgically confirmed true and false aneurysms are reported below. Example 1 male, 26 years old. Fall from 2.5 meters high, fell lower limbs, left femoral shaft fracture open reduction, intramedullary nail fixation. Postoperative thigh is still swollen, angiography showed deep distal femoral artery thick oval thick staining. Changes were cystic, uneven contrast medium density, clear boundary around the exudate changes can be seen. See the medial femoral shaft after a pack of massive tumor
