Ischemic monomelic neuropathy (IMN) is an infrequently recognized type of ischemic neuropathy produced by shunting blood or acute noncompressive occlusion of the major proximal limb artery. IMN is seen almost exclusively in diabetic hemodialysis patients. We report a case of ischemic monomelic neuropathy occurring after brachial artery puncture for arterial blood sampling. The patient was a 1-monthold female baby born at 34 weeks gestation. Right brachial artery was punctured for routine arterial blood sampling. After that her right forearm was discovered to be cyanotic. We found decreased brachial artery blood flow by doppler ultrasonography and thus performed emergency angioplasty. Thirteen days after angioplasty, electrodiagnostic study showed multiple peripheral nerve injuries of median, ulnar and radial nerves. Six months later, her forearm was fully recovered clinically and electrophysiologically. |
