Transient paraplegia after neurolytic splanchnic block in a patient with metastatic colon carcinoma

We present a patient with metastatic colon carcinoma who developed paraplegia following a neurolytic splanchnic block. A 41-year old man with metastatic adenocarcinoma of the colon received a splanchnic neurolytic block using alcohol because of severe abdominal pain. Bilateral motor weakness and a sensorial deficit in both legs developed after the procedure. Diffusion magnetic resonance imaging revealed spinal cord ischemia between T8 and L1. The motor and sensorial deficits were almost completely resolved at the end of the third month. We think that anterior spinal artery syndrome due to reversible spasms of the lumbar radicular arteries using alcohol have resulted in transient paraplegia. The retrograde spread of alcohol to neural structures may have also contributed.

Anterior spinal artery syndrome following coronary artery bypass grafting: a case report

Abstract We present a patient with unstable angina candidate for coronary artery bypass grafting. Saphenous vein graft was used in obtuse marginal and left internal mammary artery to left anterior descending artery properly. After surgery, the patient experienced flaccid paralysis of lower limb and impaired sensation of touch and warmth of knee and below. A computed tomography angiogram of lower limbs and thoracolumbar magnetic resonance imaging showed no abnormality. Based on the symptom, clinical diagnosis of anterior spinal artery syndrome was considered. The artery of Adamkiewicz is an important supplier to the anterior spinal artery. Internal thoracic mammary artery, used in coronary artery bypass grafting, is suspected as a collateral supplier of the artery of Adamkiewicz and has been accused for cause of spinal infarction.

Anesthetic Management in an Established Case of Anterior Spinal Artery Syndrome Posted for Inguinal Hernioplsty.

Anterior spinal artery syndrome (ASAS) is a rare and permanent damage, caused as a neurological complication of spinal anesthesia. In this case study, we have given account of our experience of anesthetic management of a documented case of ASAS, posted for inguinal hernioplasty. We did a thorough pre-anesthetic evaluation and found that patient had paraplegia and confi ned to bed with aspiration pneumonitis. He is a known hypertensive and on control with tablet amlodipine 5 mg/day. He was subjected to antibiotic therapy, mucolytics with respiratory physiotherapy and incentive spirometry. After preparing the patient thoroughly, patient was subjected to general anesthesia. Post-operative analgesia was provided with injection fentanyl, given with a syringe pump. Post-operative period was uneventful.

Leg Weakness After An Automobile Accident Due To Spinal Cord Ischemia: A Case Report

Anterior spinal artery syndrome, also known as Beck's syndrome, is defined as ischemia or infarction of the spinal cord. Beck's syndrome occurs from aortic thrombus, embolism, or dissection blocking the blood flow to the great radicular artery (GRA) of Adamkiewicz. Abdominal artery embolism due to trauma is relatively rare and urgent detection of vascular injury is substantial to fair clinical outcome of the patient, therefore, we report on a case of traumatic artery dissection presenting as lower leg weakness.

Antiphospholipid Syndrome Presented With Anterior Spinal Artery Syndrome

Antibodies to cardiolipin and other phospholipid have been associated with recurrent thrombotic events, including ischemic strokes, especially in children and young adults. Recently it has been shown that anti-beta2-glycoprotein I antibodies may be more specific in predicting thrombosis. We report a case of anterior spinal artery syndrome with elevated titer of antibodies to beta2-glycoprotein I in young adult.

Spinal Cord Infarction Caused by Non-dissected and Unruptured Thoracoabdominal Aortic Aneurysm with Intraluminal Thrombus

Spinal cord infarction, especially anterior spinal artery syndrome, is a relatively rare disease. We report a case of spinal cord infarction caused by thoracoabdominal aortic aneurysm with intraluminal thrombus. A 52-year-old man presented with sudden onset paraplegia. At first, he was diagnosed with cervical myelopathy due to a C6-7 herniated intervertebral disc, and had an operation for C6-7 discetomy and anterior interbody fusion. Approximately 1 month after the operation, he was transferred to the department of rehabilitation in our hospital. Thoracoabdominal aortic aneurysm with intraluminal thrombus was found incidentally on an enhanced computed tomography scan, and high signal intensities were detected at the anterior horns of gray matter from the T8 to cauda equina level on T2-weighted magnetic resonance imaging. There was no evidence of aortic rupture, dissection, or complete occlusion of the aorta. We diagnosed his case as a spinal cord infarction caused by thoracoabdominal aortic aneurysm with intraluminal thrombus.

Pure Motor Function Loss of Bilateral Upper Extremities after Anterior Spinal Cord Infarction: A case report

Anterior spinal artery syndrome refers to the paralysis of the bilateral upper extremities, bladder dysfunction and the sensory deficit of pain and temperature below the level of injury. A 64 year-old female got a cardiac arrest event after stent insertion into the coronary artery. After CPR, she underwent the motor deficit (Z-T) of the bilateral upper extremities without any sensory deficit; proprioception, vibration and pain. The brain MRI showed no abnormality, but high signal intensity was detected in C3-C7 level by T2 sagittal plane and at the anterior horn area of gray matter by axial view of spine MRI. The ventilator has been applied after CPR. By the fluoroscopy, the movement of the diaphragm was decreased, and the nerve conduction study of both phrenic nerves showed no responses.

Transient quadriplegia after fluoroscopic-guided selective cervical nerve root block in a patient who received cervical interbody fusion: A case report / 대한마취과학회지

Selective cervical nerve root block is executed for patients who have symptoms of cervical radiculopathy for diagnostic and therapeutic purposes. However several catastrophic complications caused by this procedure have been reported including neurological complications. A 43-year-old male received a C5 selective cervical nerve root block procedure due to continuous radiating pain even after cervical discectomy and interbody fusion was performed. At the time of the procedure, the contrast outline revealed reflux of the nerve root and epidural space. But after the procedure was performed, the patient experienced decreased sensation in the upper and low extremities as well as motor paralysis of both extremities. Our sspecting diagnosis was anterior spinal artery syndrome but both sensory and motor functions were subsequently recovered within a few hours after the procedure was completed. Due to the difficult nature of this case, we reported these complications and reviewed current literature related to this study.

La arteria de Adamkiewicz y su papel en la irrigación medular. Una actualización bibliográfica basada en internet / The artery of Adamkiewicz and its role in medullar irrigation. Bibliographic update based on internet

La médula espinal tiene una irrigación sanguínea mucho más compleja pero menos efectiva que el cerebro, ya que depende de vasos de diámetro muy pequeño procedentes de las arterias vertebrales. En general, la circulación suplementaria de los vasos medulares proviene de las arterias radiculares, que ingresan a la médula aprovechando las raíces nerviosas que emergen o llegan a ella. La más importante de todas es la arteria de Adamkiewicz, cuya localización ha sido motivo de muchos estudios. El origen de la arteria se da frecuentemente (en el 45 por ciento de los casos) entre los espacios T8 y T12 para las intercostales, llegando en algunas oportunidades por la L1. La mayoría de las veces son arterias intercostales o lumbares del lado izquierdo. De todas maneras, la posición exacta de la radicular magna en el hombre no permite diseñar una estrategia absolutamente confiable que descarte, por ejemplo, la posibilidad de una isquemia medular durante el clampeo de la aorta. Se han descrito alteraciones de la circulación medular que por distintos mecanismos (embolias, arterioesclerosis, anestesia regional central, etc.) pueden llevar a la isquemia de la médula con sus consecuencias clínicas.

Paraplegia Following Percutaneous Nephrolithotomy under General Anesthesia: A case report / 대한마취과학회지

We present a case of paraplegia, compatible with spinal cord ischemia, following percutaneous nephrolithotomy in a 58-year-old male under the diagnosis of left renal stone. After retroperitoneal operative procedures in the prone position, sensory loss below the level of T4, paraplegia and transient loss of visual acuity were developed. These clinical findings reflect ischemia of the anterior spinal cord with complete motor paralysis and sensory loss to T4 dermatomal level resulting from an anterior spinal artery syndrome. The initial treatment was started with intravenous heparin and corticosteroid. At present, sensory loss is almost recovered and motor deficit is remarkably improved to a level of ambulation with cane. The patient is still treated with oral coumadine and neuromotor rehabilitation. The cause of spinal cord ischemia is unknown, but we speculate ischemia of the spinal cord was associated with embolism and spasm or trauma of feeding artery (ies) of Adamkiewicz.

Anterior Spinal Artery Syndrome Associated With Cervical Spinal Stenosis

BACKGROUND: The anterior spinal artery infarction constitutes a classical syndrome of vascular myelopathy. The causes of the anterior spinal artery syndrome are various, but most episode probably occur as the result of atherosclerosis or dissection of the aorta and its branches. However, few cases reported developed with spinal structural abnormalities. CASE: A 65-year-old man presented with sudden paraparesis. There was no evidence of hypertension, diabetes and smoking. Motor weakness was more prominent on the left side and progressed. Loss of pain and temperature senses were shown at the level of 71 with preservation of touch, joint perception and vibration senses. The DTR's of legs were depressed and extensor toe signs were presented. A C-spine MRI showed high signal intensity on 72 weighted image and low signal on 71 weighted image(C6-71) with cervical spinal stenosis at the C4-C7 spinal level and mild cervical disc protrusion (C6-C7, C7-T1). After three months later, follow up cervical MRI showed somewhat decreased size of high signal intensity on 72 weighted image and more prominent low signal on 71 image. DISCUSSION: In our case, we could not find any usual cause of anterior spinal artery infarction. However only cervical spinal stenosis associated with mild cervical disc protrusion was present. In stenotic cervical canal, the anterior spinal artery can be more vulnerable to extrinsic compression and the infarction may early develop with insignificant trigger event, such as disc protrusion. We concluded that the ischemic change of anterior two thirds of cervical spinal cord might develop due to the compression of the anterior spinal artery by cervical stenosis and mild cervical intervertebral disc protrusion.
