Objective：To explore the value of multi-slice spiral computed-tomography angiography in the design of complicated abdoninal operation scheme for space-occupying lesions that involve major intraabdominal vessels.
Methods：Thirty-one patients underwent multi-slice spiral computed-tomography angiography before operation. Then, individualized operation scheme was made according to the result of multi-slice spiral computed-tomography angiography.
Results：Multi-slice spiral computed-tomography angiography accurately revealed the complicated relationship between a variety of severe intraabdoninal lesions and major intraabdoninal vessels. Individualized operation scheme for the 31 patients was made according to the result of multi-slice spiral computed-tomography angiography. Based on individualized operation schemes, all of the 31 patients successfully underwent operation without injury of major intraabdominal vessels, and were satisfactorily discharged.
Conclusions：Multi-slice spiral computed-tomography angiography is safe, convenient, authentic, accurate, high resolution, fast and non-invasive. It is very useful in planning rational individualized operation scheme for complicated intraabdominal operations that involve major intraabdominal vessels, and can help to direct and improve the effect of surgical treatment.
