Peripheral embolism to the lower extremities may mimic disc prolapse with severe consequences.
A 71-year-old male with a history of chronic alcoholism developed low back pain radiating to both lower extremities in a nonradicular distribution and bilateral dysesthesias of the distal lower legs after lifting a heavy weight. Given that magnetic resonance imaging (MRI) of the lumbar spine showed disc herniation in L3/4 and L4/5, he was scheduled for laminectomy but was unable to undergo surgery due to thrombocytopenia. After transfer to another hospital, persistence of symptoms and signs, absent pulses on the distal lower legs, and rhabdomyolysis with temporary renal insufficiency, peripheral embolism with compartment syndrome was suspected. Magnetic resonance angiography revealed occlusion of the right superficial femoral artery and long high-grade stenosis of the left superficial and profound femoral arteries and distal arteries. He successfully underwent embolectomy and fasciotomy.
If lumbar pain is not radicular, peripheral pulses are minimally palpable, and distal limbs are cold and show livid decolorization, peripheral embolism is much more likely than disc herniation, particularly if the patient's history is positive for atrial fibrillation. MRI of the lumbar spine must be interpreted in conjunction with clinical presentation.
下肢周围性栓塞可能酷似椎间盘突出,后果严重。
一名71岁男性,有慢性酒精中毒史,在搬重物后出现下背部疼痛,呈非根性分布放射至双下肢,以及双小腿远端感觉异常。鉴于腰椎磁共振成像(MRI)显示L3/4和L4/5椎间盘突出,他被安排进行椎板切除术,但因血小板减少症无法接受手术。转至另一家医院后,症状和体征持续存在,小腿远端脉搏消失,伴有横纹肌溶解和暂时性肾功能不全,怀疑为伴有骨筋膜室综合征的周围性栓塞。磁共振血管造影显示右股浅动脉闭塞,左股浅动脉和股深动脉及远端动脉存在长段高度狭窄。他成功接受了栓子切除术和筋膜切开术。
如果腰痛不是根性的,周围脉搏难以触及,远端肢体发凉且呈青紫色脱色,则周围性栓塞比椎间盘突出的可能性大得多,特别是如果患者有房颤病史。腰椎MRI必须结合临床表现进行解读。
