Acute type B aortic dissection (ATBAD) with malperfusion is a devastating complication. Especially, the spinal cord ischemia with ATBAD is very rare (3% of total malperfusion cases). Despite the possibility of various arterial involvement in ATBAD, cases of monoplegia due to spinal cord ischemia are extremely rare. Furthermore effective treatments for malperfusion induced spinal cord ischemia have not been established yet. We presented a case of a 62-year-old man with a sudden onset of chest pain and numbness and weakness of the left lower extremity. Follow up CT demonstrated ATBAD starting from below the left subclavian artery to the level of iliac bifurcation without distal reentry, involving malperfusion of the left renal, left intercostal and left lumbar arterial branches. Deciding on endovascular fenestration approach under considering his condition and comorbidity, the right common femoral artery was catheterized and a 5Fr sheath catheter was positioned into the true lumen (Cook Medical, IN, USA). After confirming the catheter was within the compressed true lumen, then aortic fenestration ballooning was performed to enlarge a tearing site by using 12-mm and 20-mm diameter balloons (Boston Scientific, Natick, Mass). The final angiography was demonstrated increased flow in the true lumen of descending aorta with good patency of the left renal artery where no flow had been observed. And enhanced CT confirmed the recovery of flow to the left intercostal and left lumbar branches. Finally the patient achieved the complete recovery of sensory and motor function of his left leg (His preoperative motor grade was 5/0). On postoperative day 3, he walked using a q-cane and now is being followed up on an outpatient basis without no complications. So, we would like to introduce this rare care of left lower monoplegia with ATBAD and suggest endovascular fenestration can be an effective treatment option to treat spinal cord ischemia in ATBAD.

Acute aortic dissection (AD) is a life-threatening emergency. The most common symptom of AD is chest pain, more frequently associated with Type-A AD per the Stanford classification, while Type-B AD is associated with back and abdominal pain. Conversely, monoplegia is an uncommon symptom of AD. We encountered a case of transient monoplegia caused by Stanford type-B AD. A 75-year-old man presented with acute-onset lumbar back pain with monoplegia. Lumbar radiography revealed multiple compression fractures and spinal-canal stenosis, and accordingly acute spinal-cord compression was suspected. Monoplegia subsided after a diclofenac suppository was administrated to reduce his pain. However, the patient's right lower-extremity pain and paralysis worsened at rest during the stay. Computer tomography angiography revealed Stanford type-B AD and the false lumen obstructing the right common iliac artery. Monoplegia in type-B AD can develop due to spinal-cord or lumbosacral-plexus ischemia. Malperfusion, determined by the balance of the pressure in the false and true lumens and subsequent end-organ ischemia, may produce transient or persistent symptom patterns. Emergency physicians need to suspect AD when a patient presents with monoplegia or transient symptom patterns of unknown etiology.
