Abstract:
Objective To observe the value of cone-beam CT (CBCT) for identifying whether the suspected responsibility artery found with DSA was the real responsibility artery of massive hemoptysis during emergent arterial embolization. Methods Data of 31 patients with massive hemoptysis underwent emergent arterial embolization were retrospectively analyzed. CBCT was used for qualitative diagnosis of suspected responsibility artery found with DSA. According to whether it was the feeding vessel of the target lesion in lung on CBCT image, the responsibility artery of massive hemoptysis was determined. Embolization was performed on the definite responsibility artery and the indefinite feeding vessel judged with CBCT, while the irresponsible artery judged with CBCT was not embolized. Results In 31 patients, haemoptysis was stopped within 24 h after emergent arterial embolization. There were 37 suspected responsibility arteries found with DSA. A total of 34 (34/37, 91.89%) suspected responsibility arteries in 29 (29/31, 93.55%) patients were definitely judged whether they were responsibility arteries of massive hemoptysis or not with CBCT, including 11 (11/37, 29.73%) of definite responsibility arteries and 23 (23/37, 62.16%) of irresponsible arteries. The other 3 (3/37, 8.11%) suspected responsibility arteries in 2 (2/31, 6.45%) patients were indefinite feeding vessels judged with CBCT which were difficult to determined whether they were responsibility arteries or not. Conclusion CBCT is useful to determine whether a suspected responsibility artery is the real responsibility artery of massive hemoptysis during emergent arterial embolization.
