Preservation of deep inferior epigastric artery at kidney transplantation prevents atrophy of lower rectus abdominis muscle.

Abstract

BACKGROUNDS:

The deep inferior epigastric artery (DIEA), which feeds the lower rectus abdominis muscle (lower RAM), is usually transected in kidney transplantation. In this study, we investigated whether preservation of DIEA can prevent lower RAM atrophy.

METHODS:

Two hundred and forty-five kidney transplant recipients (150 men and 95 women) were enrolled in the study (mean age 39.9 years) and were divided into two groups according to whether DIEA was transected (group A, n = 175) or preserved (group B, n = 70). The extent of lower RAM atrophy calculated in computed tomography (performed 1 year after transplantation) and incidence of lower RAM atrophy were compared between the two groups. The most predictive factors for lower RAM atrophy were assessed using a multivariate logistic regression model.

RESULTS:

The extent of lower RAM atrophy was significantly lower in group B (15.0 ± 18.5%) than that in group A (38.9 ± 25.4%, P = 0.003). The incidence of lower RAM atrophy was less prevalent in group B (20.0%) compared with that in group A (62.9%, P < 0.001). The sacrifice of DIEA was the only independent predictive factor for lower RAM atrophy (P < 0.001).

CONCLUSIONS:

Preservation of DIEA during kidney transplant can prevent lower RAM atrophy.
