Coarctation and occlusion of the aorta is a rare condition that typically presents with hypertension or cardiac failure. However, neuropathy or myelopathy may be the presenting features of the condition when an intraspinal subarachnoid hemorrhage has compressed the spinal cord causing ischemia. We report two cases of middle-aged males who developed acute non-traumatic paraplegia. Undiagnosed congenital abnormalities, such as aortic coarctation and occlusion, should be considered for patients presenting with nontraumatic paraplegia in the absence of other identifiable causes. Our cases suggest that spinal cord ischemia resulting from acute spinal subarachnoid hemorrhage and can cause paraplegia, and that clinicians must carefully examine patients presenting with nontraumatic paraplegia because misdiagnosis can delay initiation of the appropriate treatment.

We report a case of fatal aortic tumor embolism presenting as acute paraplegia. A four-year-old girl was referred from a local hospital with sudden paraplegia and a poor medical condition. A neighbor had noticed her fall from a bike, and she could not walk. She had no previous illness. Emergency spine MRI revealed no remarkable findings. During the process of evaluation, her general condition deteriorated progressively. Chest and abdominal CT showed a large mass in the left lung field, and a diagnosis of aortic occlusion was made. An emergency transfemoral embolectomy was attempted. However, the patency of the aorta was not recovered. On pathological examination of tissues taken from the embolectomy, a pleuro-pulmonary blastoma was found. The patient died 22 hours after the onset of her symptoms. We describe a possible mechanism for the tumor embolism. To the best of our knowledge, this is the first case report of aortic occlusion caused by an embolic malignancy, presenting as acute paraplegia.

Acute intraabdominal aortic obstruction ends in progressive fatal course or severe permanent disability unless it is diagnosed and treated promptly. However, the incidence of such disease is very rare, so there is very little chance for a neurosurgeon to encounter a patient with acute intraabdominal aortic obstruction. The authors present a case of 62-year-old man with severe low back pain and acute paraplegia caused by acute intraabdominal aortic obstruction.

45세 여자 환자에서 요하지통의 치료를 위해 triamcinolone 40 mg과 0.125% bupivacaine 10 ml를 경막외로 주입한후 24시간에 걸쳐 하지마비 및 해리성 감각소설이 발생하였다. 그 원인은 분명하지 않으나 선행절환의 악화, 급성 횡단성 척수염, 전척수동맥증후군, 그리고 신경독성등이 추정된다.

Spinal cord infarction is uncommon and usually presents with sudden onset of motor and sensory disturbances. We report a case of a 64-year-old women without previous medical history, who presented with acute onset of paraplegia after lifting. However, radiologic examinations did not show any abnormal lesion in the spinal cord. And, cerebrospinal fluid studies also showed no remarkable findings. This case illustrates the cause of spontaneous paraplegia after lifting injury and we consider the presumptive cause of paraplegia as spinal cord infarction.

경추간판탈출증 환자에서 척수조술을 위해 요추천자를 시행한 후에 갑자기 양하지마비가 발생한 1례를 보고 한다. 척추종괴환자에서 요추천자후 합병증으로 나타나는 운동마비는 요추천자후 1~4일째에 서서히 오는 경우가 일반적이며, 수시간내에 급성으로 하지마비를 나타내는 경우는 매우 드물어 현재까지 6례 정도만 보고되고 있을뿐이며 그 원인질환은 대부분 척수종양이다. 경추간판탈출증 환자에서 척수조술을 위해 요추천자를 시행한 후에 갑자기 양하지마비가 발생한 임상보고례는 현재까지 없다. 이러한 합병증을 막기위해서는 척수장애증상을 보이는 경추간판탈출증 환자에게 척수조술대신에 자기공명촬을 시행함이 현명하리라 본다. 이러한 합병증이 올 수 있는 기전과 예방방법에 대해 고찰하다.

Acute paraplegia attributable to disc herniation is known to occur most frequently at the thoracic level. A 50-year-old male presented with progressive limb weakness and hypoactive deep tendon reflexes. On the basis of clinical features and neurological findings, the diagnosis of Guillain-Barre syndrome was suspected. Spinal MRI showed cervical disc herniation. He underwent emergency surgery consisting of removal of herniated disc and anterior fusion. We emphasize that there is a possibility of acute progression of paralysis secondary to nontraumatic enlargement of cervical disc herniation.

Authors report a case of a painless acute dissecting aneurysm of the descending aorta in a patient who presented with unexplained hypotension followed by simultaneous paraplegia and right arm monoparesis. To our knowledge, case like this has not been reported previously. Magnetic resonance imaging of the brain and spine revealed hemodynamic cerebral infarction and extensive cord ischemia, respectively. Computerized tomography angiography confirmed a dissecting aneurysm of the descending aorta. The cause of the brain infarction may not have been embolic, but hemodynamic one. Dissection-induced hypotension may have elicited cerebral perfusion insufficiency. The cause of cord ischemia may be embolic or hemodynamic. The dissected aorta was successfully replaced into an artificial patch graft. The arm monoparesis was improved, but the paraplegia was not improved. In rare cases of brain and/or spinal cord infarction caused by painless acute dissecting aneurysm of the aorta, accurate diagnosis is critical because careless thrombolytic therapy can result in life-threatening bleeding.

Background: We aimed to evaluate the incidence, predictive factors, and impact of acute kidney injury (AKI) after thoracic endovascular aortic repair (TEVAR). Methods: A total of 53 patients who underwent 57 TEVAR operations between 2008 and 2015 were reviewed for the incidence of AKI as defined by the RIFLE (risk, injury, failure, loss, and end-stage kidney disease risk) consensus criteria. The estimated glomerular filtration rate was determined in the perioperative period. Comorbidities and postoperative outcomes were retrospectively reviewed. Results: Underlying aortic pathologies included 21 degenerative aortic aneurysms, 20 blunt traumatic aortic injuries, six type B aortic dissections, five type B intramural hematomas, three endoleaks and two miscellaneous diseases. The mean age of the patients was $61.2{\pm}17.5years$ (range, 15 to 85 years). AKI was identified in 13 (22.8%) of 57 patients. There was an association of preoperative stroke and postoperative paraparesis and paraplegia with AKI. The average intensive care unit (ICU) stay in patients with AKI was significantly longer than in patients without AKI (5.3 vs. 12.7 days, p=0.017). The 30-day mortality rate in patients with AKI was significantly higher than patients without AKI (23.1% vs. 4.5%, p=0.038); however, AKI did not impact long-term survival. Conclusion: Preoperative stroke and postoperative paraparesis and paraplegia were identified as predictors for AKI. Patients with AKI experienced longer average ICU stays and greater 30-day mortality than those without AKI. Perioperative identification of high-risk patients, as well as nephroprotective strategies to reduce the incidence of AKI, should be considered as important aspects of a successful TEVAR procedure.

Chondrosarcoma is a very uncommon malignant primary bone tumor, especially, it occurs extremely rare in the spine. A 52-year-old man was admitted to the emergency room with sudden paraplegia. Twelve hours prior to a paraplegic event, he visited an outpatient clinic with discomfort and tenderness around the medial border of the right scapular, and his neurologic status was absolutely intact. Magnetic resonance imaging showed a lobulated soft tissue mass from T3 to T5, which extended to the epidural space. Computed tomography scans showed soft tissue mass on the spinal posterior arch and osteolytic change of the adjacent bony structures. Emergent surgery was performed and the lesion was removed. Dark reddish blood and gel-like material were encountered around the dura and posterior arch during the operation. Multiple pulmonary nodules were found on a chest CT scan and a biopsy of one of them had been proven to be a metastasis of chondrosarcoma. The histologic examination showed dedifferentiated chondrosarcoma. The patient's neurologic deficit was improved slowly from ASIA A to ASIA D. Chondrosarcoma in the spine is extremely rare, even more with acute hemorrhage and sudden expansion into the epidural space. We named it chondrosarcoma apoplexy. We should consider the possibility of a hemorrhagic event when the patient's neurologic deficit worsens suddenly with spinal bone tumor.
