背景本研究的目的是确定是否Adamkiewicz动脉（ARM）可以通过磁共振血管造影检测，并确定术前磁共振血管造影评估ARM的有用性。2000年4月至2003年12月，120例患者接受了磁共振血管造影术检测ARM。99例术前检测到ARM的患者中，磁共振血管造影术显示ARM交界处的脊髓前动脉形态分为以下三种类型：脊髓前动脉在ARM交界处以上不延续（A型），脊髓前动脉在ARM交界处上下延续（B型），脊髓前动脉在ARM交界处以下不延续（C型）。在120例患者中，99例（83%）检测到ARMs，总共110例ARMs中，105例（95%）起源于左侧肋间动脉分支，94例（86%）起源于Th.9和Th11之间。在99例检测到ARM的患者中，11例（11%）发现了两种ARM。107例患者接受磁共振血管造影以显示脊髓前动脉在ARM交界处的形态，其中59例患者（55%）的脊髓前动脉类型为A型，21例患者（20%）为B型，3例患者（3%）为C型，24例患者（22%）未分类。术前检测到ARM的患者无脊髓损伤发生。术前通过磁共振血管造影检测ARM是可能的，并且对于降低脊髓缺血性损伤的发生率非常有用。(C)2004年由胸外科医师协会发布。
Background. The purpose of this study was to determine whether the artery of Adamkiewicz (ARM) can be detected by magnetic resonance angiography and to determine the usefulness of preoperative magnetic resonance angiography evaluation of the ARM.Methods. Between April 2000 and December 2003, 120 patients underwent magnetic resonance angiography for detection of the ARM. The morphology of the anterior spinal artery at the ARM junction, as revealed by magnetic resonance angiography, in 99 patients in whom ARM was preoperatively detected was classified into the following three types: noncontinuation of the anterior spinal artery above the ARM junction (type A), continuation of the anterior spinal artery above and below the ARM junction (type B), and noncontinuation of the anterior spinal artery below the ARM junction (type C).Results. The ARMs were detected in 99 (83%) of 120 patients, and from a total of 110 ARMs 105 (95%) originated from intercostal arteries branching from the left side and 94 (86%) originated between Th.9 and Th11. Two ARMs were found in 11 (11%) of 99 patients in whom ARMs were detected. In 107 patients, who underwent magnetic resonance angiography to reveal the morphology of the anterior spinal artery at the ARM junction, the patterns of the anterior spinal artery were type A in 59 patients (55%), type B in 21 patients (20%), type C in 3 patients (3%) and not classified in 24 patients (22%). No spinal cord injury occurred in patients in whom the ARM had been preoperatively detected.Conclusions. Preoperative detection of the ARM is possible by magnetic resonance angiography and is very useful for reducing the incidence of ischemic injury of the spinal cord.
