Common features in patients with intracerebral hemorrhage following superficial temporal artery-middle cerebral artery bypass in steno-occlusive cerebrovascular disease.

Mao Z, Li M, Ma Y, Chen Y, Zhang H, Ling F - Neural Regen Res (2012)

Bottom Line: Intracranial cerebral hemorrhage developed within 1-4 days following superficial temporal artery-middle cerebral artery bypass.Transcranial Doppler showed increased middle cerebral artery velocity of 50-100% in the operated hemisphere.These findings suggested that focal hyperperfusion, an ipsilateral ischemic lesion and diminished cerebrovascular reactivity are the important characteristics of intracerebral hemorrhage following superficial temporal artery-middle cerebral artery bypass in patients with steno-occlusive cerebrovascular disease.

ABSTRACT
Five patients treated for intracranial cerebral hemorrhage after superficial temporal artery-middle cerebral artery bypass in Xuwu Hospital, Capital Medical University, Beijing, China, from 2005-2011 were included in this study. Prior to superficial temporal artery-middle cerebral artery bypass, all patients showed diminished cerebrovascular reactivity and an ipsilateral ischemic lesion. Intracranial cerebral hemorrhage developed within 1-4 days following superficial temporal artery-middle cerebral artery bypass. Transcranial Doppler showed increased middle cerebral artery velocity of 50-100% in the operated hemisphere. These findings suggested that focal hyperperfusion, an ipsilateral ischemic lesion and diminished cerebrovascular reactivity are the important characteristics of intracerebral hemorrhage following superficial temporal artery-middle cerebral artery bypass in patients with steno-occlusive cerebrovascular disease.

MRI and CT images of a 47-year-old male patient with intracerebral hemorrhage following superficial temporal artery-middle cerebral artery (STA-MCA) bypass.An ischemic lesion appeared in the left frontotemporal lobe (white arrow) on preoperative MRI (A, B). The time to peak cerebral blood flow velocity in the frontotemporal lobe was delayed compared with the contralateral side (C). CT scan demonstrated left frontotemporal hemorrhage (white arrow) on the first day after STA-MCA bypass (D). L: Left; R: right.

The time to peak cerebral blood flow velocity in the frontotemporal lobe was delayed compared with the contralateral side (C).

Mentions: After STA-MCA bypass, cases 1–3 required blood pressure control with intravenous urapidil. Blood pressure in cases 4, 5 was stable [systolic pressure/ diastolic pressure less than 150/95 mm Hg (1 mm Hg = 0.133 kPa)]. Cases 1 (Figure 1) and 2 (Figure 2) had only temporary high blood pressure (≥ 200 mm Hg systolic pressure, or ≥ 110 mm Hg diastolic pressure) because medication was not used continuously.
