Objective To evaluate the feasibility of dual microcatheter "cross-regional" embolization technique in treating intracranial irregular aneurysms. Methods The clinical data of 19 patients with intracranial irregular aneurysms, who were treated with "cross-regional" embolization technique at authors' hospital during the period from May 2016 to May 2017, were retrospectively analyzed. The embolization strategy formulation, selection of embolization materials, surgical process and embolization effect were summarized. Results Successful treatment of intracranial irregular aneurysm was accomplished in all the 19 patients. In one patient, during the embolization process of the neck of aneurysm the steel coil was over-protruded into the parent artery, and stent implantation had to be carried out to rescue the therapy, and finally successful treatment was achieved. The technical success rate of "cross-regional" embolization was 95％. Complete embolization was obtained in 15 patients and subtotal embolization in 3 patients. Conclusion For the treatment of some specified intracranial irregular aneurysms, dual microcatheter "cross - regional" embolization technique is technically simple, and it is a safe and effective treatment option.
