title: [Difficult hemodialysis induction due to subclavian steal syndrome in a patient with Takayasu's arteritis].
abstract: The patient was a 53-year-old woman who had bilateral renal arterial constriction due to Takayasu's arteritis, and developed end-stage renal failure. When transient loss of consciousness occurred in 2002, she was diagnosed with subclavian steal syndrome (SSS). The renal failure worsened in June 2004, and there was concern that the left SSS could become aggravated as a consequence of creating an arterio-venous (AV) shunt. Although peritoneal dialysis was strongly recommended, she elected to undergo hemodialysis. We confirmed that there was no reduction of cerebral blood flow using brain single photon emission computed tomography (SPECT). Right and left examinations indicated the site at which an AV shunt should be created and subsequently, the AV shunt was created on the left fore-arm. Brain SPECT findings were again confirmed after dialysis, at the time of hemodialysis induction, and again 2 years after hemodialysis induction, showing no reduction in cerebral blood flow. She has no apparent symptoms or signs of left SSS, to date. Although it is known that an SSS could arise after AV shunt creation, there has been no report of the creation of an AV shunt in a case of SSS. The present case suggests that cerebral blood flow measurement using brain SPECT is useful for evaluating cerebral hemodynamics before AV fistula creation among patients with Takayasu's arteritis.
