摘要
目的:探导非创伤性股骨头缺血性坏死骨髓水肿(BME)的数字减影血管造影(DSA)表现特征,并分析其原因和发生机制。方法:35例(55侧髋关节)经确诊拟行血管内介入治疗的非外伤性股骨头缺血性坏死患者,术前常规行MR I检查,根据有无出现骨髓水肿分为两组,与治疗前DSA表现作对照研究。结果:55例患者中髋关节MR I示骨髓水肿阳性为37个髋关节、阴性为18个髋关节;阳性的37个髋关节中36个于DSA静脉期见水肿相应部位呈淤血改变,1个髋关节未见淤血。阴性的18个髋关节中有3个呈淤血表现,15个未见淤血。结论:股骨头缺血性坏死患者MR I所示的骨髓水肿和DSA所见的淤血表现密切相关,其分级与坏死分期呈正相关,骨髓水肿的形成可能与静脉回流受阻和髓内高压相关。
Objective ：To determine the characteristics on DSA and to discover the pathogenesis of bone marrow edema in patients of non-traumatic avascular necrosis of the femoral head. Methods ：Thirty-five patients with 55 hips showing avasculer necrosis of the femoral head were divieded into two groups according to with or without bone marrow edema pattern on MR images, then compared with the result of DSA accordingly. Results ：Thirty-six of 37 hips with marrow edema around focal osteoneersis on initial MR inages showed congestion on DSA,one showed no congestion; whereas only three of 18 hips without bone marrow edema showed congestion, fifteen showed no congestion. Conclusion：The bone marrow edema around focal osteonecrosis on magnetic resonance images is strongly associated with medullary cavity congestion on DSA and assocoated with the grading of ANFH, the form of bone marrow edema may associated with blockage of the venous outflow or high pressure in bone medullary.
