To evaluate and reconstruct three-dimensional images of vascularization along the fallopian tube (FT), as well as to determine its relationship with the ovary and ovarian fimbria, and to quantify the blood vessels along the FT according to its anatomical segments, using confocal microtomography (micro-CT).
Nine specimens (six FTs and three FTs with ovaries) were fixed in a solution of 10% formalin for > 24 h at room temperature. Iodine staining was performed by soaking the specimens in 10% Lugol's solution for 24 h. All specimens were evaluated using micro-CT. A morphometric analysis was performed on the reconstructed images to quantify the vascular distribution along the FT.
In the FTs evaluated, the density of blood vessels was significantly greater in the fimbrial segments than in the isthmic segments ( < 0.05). The ovarian fimbria was clearly identified, demonstrating the important relationship between these vessels and the FT fimbriae.
We believe that the vascularization in the fimbriae is greater than and disproportional that in the other segments of FT, and that the ovarian fimbria plays an important role in the development of that difference.
利用共聚焦显微断层扫描技术（显微CT）评估并重建输卵管（FT）的血管三维图像，确定其与卵巢及卵巢伞的关系，并根据FT的解剖节段对其血管进行量化分析。
9个标本（6条输卵管及3条带卵巢的输卵管）在室温下于10%福尔马林溶液中固定超过24小时。通过将标本浸泡在10%卢戈氏溶液中24小时进行碘染色。所有标本均采用显微CT进行评估。对重建图像进行形态计量分析，以量化FT上的血管分布。
在所评估的输卵管中，伞部血管密度明显高于峡部（<0.05）。卵巢伞清晰可见，表明这些血管与输卵管伞之间存在重要关系。
我们认为，输卵管伞部的血管化程度高于且不成比例于输卵管的其他节段，并且卵巢伞在这种差异的形成中起重要作用。
