Using a bifrontal trans-interhemispheric approach, we have performed direct operations on 206 cases of aneurysm of the anterior communicating artery, 44 of which (21.4%) had vascular anomalies associated with the aneurysm. Those anomalies included 27 cases (13.1%) with median artery of the corpus callosum, 20 cases (9.7%) with duplication of the anterior communicating artery and one case (0.5%) with duplication of the A1 portion. Preoperative diagnosis of the duplications was not possible on the basis of angiograms. Moreover, preoperative diagnosis of the median artery using angiography was unambiguous in only 11 of the 27 cases (41%). The majority (81.5%) of the aneurysms of the anterior communicating artery in cases with a median artery of the corpus callosum were found to develop at the trifurcation of the anterior communicating artery, the A2 portion and the median artery of the corpus callosum.
采用双额经半球间入路，我们对206例前交通动脉瘤患者进行了直接手术，其中44例（21.4%）动脉瘤伴有血管异常。这些异常包括27例（13.1%）胼胝体正中动脉、20例（9.7%）前交通动脉重复以及1例（0.5%）A1段重复。根据血管造影术前无法诊断重复情况。此外，27例中仅11例（41%）通过血管造影对正中动脉进行的术前诊断明确。在伴有胼胝体正中动脉的病例中，大多数（81.5%）前交通动脉瘤位于前交通动脉、A2段和胼胝体正中动脉的三叉处。
