By preservingthese macular lesions, the creation of larger defects during excision is avoided.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:AIM: To characterize the macular lesions associated with spinal dysraphism and to determine the outcomes of cases in whichmacular lesions are not excised.MATERIAL and METHODS: The patient cohort comprised 17 patients with spinal dysraphism who were treated at Mersin UniversityHospital from 2005 through 2007.
📊
Key Findings & Data:Blood and tissue samples were obtained from these patients.RESULTS:Electron microscopy results of tissue samples obtained from macular lesions are not consistent with those of hemangiomas.Increased numbers of vessels and significant dilatation was noted upon examination by light microscopy.
💡
Conclusion & Impact:By preservingthese macular lesions, the creation of larger defects during excision is avoided.

AIM: To characterize the macular lesions associated with spinal dysraphism and to determine the outcomes of cases in whichmacular lesions are not excised.MATERIAL and METHODS: The patient cohort comprised 17 patients with spinal dysraphism who were treated at Mersin UniversityHospital from 2005 through 2007. Blood and tissue samples were obtained from these patients.RESULTS:Electron microscopy results of tissue samples obtained from macular lesions are not consistent with those of hemangiomas.Increased numbers of vessels and significant dilatation was noted upon examination by light microscopy. The number of mast cellnumbers, blood estradiol levels, expression of tissue inhibitor matrix metalloproteinase-1 (TIMP-1) and vascular endothelial growthfactor (VEGF), and dermal collagen fiber diameter were within normal range. Estrogen receptor-β was not expressed. The numberof endothelial cells expressing Von-Willebrand factor was higher in the macular lesions.CONCLUSION: The characteristics of macular lesions associated with spinal dysraphism are consistent with those of capillarymalformations. We believe that the preservation of these macular lesions during soft tissue reconstruction of spinal dysraphismdefects, either by mobilization on a flap or primary closure, does not compromise the viability of the macular region. By preservingthese macular lesions, the creation of larger defects during excision is avoided.
