We report a case of a patient with thromboembolic arterial occlusion of the right lower extremity, which was misconceived as foraminal stenosis at the right L3-4 level. A 75-year-old man underwent paramedian microdecompression at the right L5-S1 level for far lateral disc herniation. Six weeks after the operation, he complained of sudden severe pain in the right anterior thigh. Physical examination did not reveal any symptoms and signs suggesting vascular ischemia in the right leg. Foraminal stenosis at the L3-4 level was initially considered the causative pathology. Since conservative treatment did not work, we planned a second spine operation at the right L3-4 level. However, preoperative Doppler ultrasonography and computed tomography angiogram of bilateral lower extremities revealed total occlusion of arteries from the right common iliac artery to the common femoral artery. The patient was transferred to the vascular center of the university hospital and he underwent a vascular operation to remove the embolus. After the vascular operation, his leg symptoms improved. |
