Delayed-Onset Paraplegia after Type A Dissection Repair / 日本心臓血管外科学会雑誌

ABSTRACT

We present the case of a 53-year-old man who developed delayed-onset paraplegia after type A dissection repair. He was referred to our hospital with a diagnosis of type A dissection, for which we performed total arch replacement. Although the patient started walking on postoperative day 4, on postoperative day 5, he developed lower limb paraplegia without any precipitating episodes. Computed tomography showed that the false lumen was thrombosed in the upper descending thoracic aorta and hypoperfused in the lower descending thoracic aorta. The cerebrospinal fluid was immediately drained to maintain the spinal pressure at 14 cm H₂O for four days. Although the patient began to move his legs immediately after treatment, he remained paraparetic, and was transferred to another rehabilitation hospital on postoperative day 40.
