“…In addition, blood was injected at the same lumbar level (L4) in each rabbit, but the AKA is often variable. An autopsy study by Koshino et al ., showed that this artery was located on the left side in 72% and between Th8 and L1 in 91%,[ 38 39 ] and dilatation did not occur same degree in all animals. We stated that bowel and bladder dysfunction occurred in animals with SAH, however bladder dysfunction was not quantified.…”

Context:Somato-sensitive innervation of bowels are maintained by lower segments of spinal cord and the blood supply of the lower spinal cord is heavily dependent on Adamkiewicz artery. Although bowel problems are sometimes seen in subarachnoid hemorrhage neither Adamkiewicz artery spasm nor spinal cord ischemia has not been elucidated as a cause of bowel dilatation so far.Aims:The goal of this study was to study the effects Adamkiewicz artery (AKA) vasospasm in lumbar subarachnoid hemorrhage (SAH) on bowel dilatation severity.Settings and Design:An experimental rabbit study.Materials and Methods:The study was conducted on 25 rabbits, which were randomly divided into three groups: Spinal SAH (N = 13), serum saline (SS) (SS; N = 7) and control (N = 5) groups. Experimental spinal SAH was performed. After 21 days, volume values of descending parts of large bowels and degenerated neuron density of L5DRG were analyzed.Statistical Analysis Used:Statistical analysis was performed using the PASW Statistics 18.0 for Windows (SPSS Inc., Chicago, Illinois). Two-tailed t-test and Mann-Whitney U-tests were used. The statistical significance was set at P < 0.05.Results:The mean volume of imaginary descending colons was estimated as 93 ± 12 cm3 in the control group and 121 ± 26 cm3 in the SS group and 176 ± 49 cm3 in SAH group. Volume augmentations of the descending colons and degenerated neuron density L5DRG were significantly different between the SAH and other two groups (P < 0.05).Conclusion:An inverse relationship between the living neuronal density of the L5DRG and the volume of imaginary descending colon values was occurred. Our findings will aid in the planning of future experimental studies and determining the clinical relevance on such studies.
