| description | To evaluate blood supply in the anal canal, rectal wall and mesorectal fat of men and women, using color Doppler endorectal sonography to establish normal ranges for vascular parameters.
A prospective cross-sectional study conducted at a tertiary-care hospital recruited asymptomatic volunteers (≤50 years). Vascularity percentage and index were calculated for defined regions.
Vascularity percentage and index were significantly higher in the puborectalis, mid-level external and upper internal anal sphincter compared to the low anal canal; these parameters were higher in men than in women at upper and middle levels of the inner anal canal structures. At mid-level, vascularity was greater in the external compared to the internal anal sphincter in both sexes; however, at the upper level it was greater in the puborectalis compared to the internal anal sphincter in women. Vascularity was greater in the rectal wall compared to the mesorectal fat, with no difference between middle and lower levels.
Blood supply is highest at upper levels of the anal canal; however, inner structures are better irrigated in men. Moreover, the rectal wall is better irrigated than the mesorectal fat. Establishing normal ranges may permit future comparisons of the studied structures in disease states as well as the hormonal and age related changes.
Avaliar vascularização do canal anal, parede retal e gordura mesorretal em homens e mulheres, usando ultrassonografia endorretal com Doppler colorido para estabelecer parâmetros vasculares de normalidade.
Estudo prospectivo transversal incluindo voluntários assintomáticos com até 50 anos. Medidos os valores da porcentagem e do índice de vascularização foram calculados para regiões escolhidas.
Valores da porcentagem e do índice foram significativamente maiores no puborretal, esfíncter externo (canal anal médio) e o esfíncter interno (canal anal superior) comparado ao canal anal inferior; esses parâmetros foram maiores em homens que em mulheres no canal anal médio e alto. No médio, a vascularização foi maior no esfíncter externo comparado ao interno em ambos os sexos; contudo, no canal anal superior, foi maior no puborretal comparado ao esfíncter anal interno em mulheres. A vascularização foi maior na parede retal comparada à gordura mesorretal, sem diferenças entre os níveis.
O suprimento sanguíneo é maior nos níveis altos do canal anal. As estruturas internas são mais irrigadas nos homens. A parede retal é mais irrigada que a gordura mesorret |
