Application of CTA in the diagnosis of aortic dissection

Objective To evaluate the clinical application of CT angiography(CTA) in the diagnosis of aortic dissection. Methods 35 cases of aortic dissection underwent CTA and all cases were confirmed by operation. Results CTA images could clearly show the lesions of aortic dissection and its complicated anatomic relationship. The aortic double lumen, the intimal flap and the affected area was showed on all cases. The CTA diagnosis coincided will with the operative findings in 100%. Conclusions CTA is helpful in correct diagnosis and guiding operation and may replace conventional angiography in aortic dissection in future.
