Purpose : Clinical course of delayed spinal cord injury had not been completely understood. Therefore, we investigated about the prevalence and clinical course of delayed SCI.
Methods : We identified 167 patients who underwent open thoracoabdominal aorta replacement between 1996 and 2020. Of this group, 19 patients (12.1%) suffered spinal cord injury after the surgery, including 8 patients (8/167, 4.8%) showed delayed paraplegia or paraparesis occurring after a period of the normal neurologic function. We analyzed the clinical course of the delayed SCI patient to compare with patients who do not have SCI.(8 patient vs 149 patients)
Results : The mean age was 55±16.2 years in total group and median follow up period was 40.5 (range: 0~252) months. The median duration for onset of delayed SCI was 2 (range: 1~32) days. Six patients (75%) were recovered after adequate treatment. One patient (12.5%) were able to walk with a cane at discharge and recovered gradually. Meanwhile, one patient (10%) was transferred for rehabilitation with persistent paraparesis. (Table1.)
The patients in the delayed SCI group had more underlying hypertension significantly. (60.8% vs 100 %, p=0.022) In operative data, CPB time (175.3 vs 237.6min, p=0.029) and ACC time is longer in the delayed SCI group. (145.3vs189.3min, p=0.026)
Conclusion : In our cases, most of patients with delayed spinal cord injury were recovered with adequate treatment. Closed observation should be necessary to the patients who have factors such as underlying hypertension or longer CPB and ACC time during operation.
