Objective: To determine mean cerebral blood flow in anemia secondary to chronic renal failure by doppler ultrasound and to compare the results with data gathered from healthy control subjects.
Study Design: Case control study.
Place and Duration of Study: Combined Military Hospital, Lahore, from Jan 2011 to Jun 2011.
Patients and Methods: A total of 60 subjects were included who were divided into two groups. Group I had 30 patients with anemia due to chronic renal failure while group II consisted of 30 healthy control subjects. Doppler for both groups was performed with a 7.5-MHz transducer of color doppler machine ALOKA SSD-5500 in a dimly lit room with a comfortable temperature (22°C–24°C) after an adaptation period of at least 15 minutes rest, in supine position. The internal carotid and vertebral arteries on both sides were examined in both groups and
Results: Patients with anemia due to chronic renal failure were found to have increased cerebral blood flow as compared to normal healthy individuals.
Conclusion: Cerebral blood flow increases in patients with anemia due to chronic renal failure.
