“…Among these cases, 5 procedures were unsuccessful and were succeeded immediately with surgical intervention or a second TAE. [3–6] After temporal success in another 5 patients, refilling of the aneurysm on follow-up imaging and recurrence of symptoms was documented. [7–11] The reasons for failure of a TAE were complicated, but may be related to the greatly enlarged bronchial artery and revascularization by collateral arteries.…”

Background:Bronchial artery aneurysm (BAA) is an uncommon but potentially life-threatening disease, and multiple BAAs are even rarer. Clinically, the tortuous and short neck of a BAA may present significant challenges for invasive intervention.Methods:This report describes the detailed process of diagnosis and treatment and includes a literature review of the etiology, clinical presentation, and therapeutic management of BAA.Results:A rare case of multiple BAAs, with one having an inflow artery arising from the brachiocephalic trunk, was referred to our hospital. The patient was successfully treated with coil embolization and brachiocephalic artery stent placement. In addition, we conducted a literature review involving 63 cases of BAA. BAA was most commonly associated with bronchiectasis and was located predominantly in the mediastinum. There was no significant difference between the diameters of the ruptured aneurysms and those of the nonruptured aneurysms (P = 0.115). Transcatheter arterial embolization was the most commonly adopted technique to treat BAA, while thoracic aortic endovascular repair was selected if the neck between the aneurysm and the aorta was short. Subgroup analysis suggested that patients with > 1 BAA were significantly more likely to be female than male (χ2 test, P = 0.034).Conclusion:Transcatheter coil embolization combined with stent placement could be a reasonable treatment option for BAAs with a tortuous and short neck. According to our literature review, patients with multiple BAAs display distinctive clinical characteristics compared with patients with a single BAA.

“…[3,10,17,20–28] These patients were slightly younger (mean age, 50.7 years) than cases of single BAA reported in the literature (mean age, 59.3 years). We also observed that patients with >1 BAA were significantly more likely to be female (80%) than male ( χ 2 test, P = 0.034).…”

“…21 The presentations of BAA are related to the size, location, and complications. The most common symptom of multiple BAAs is hemoptysis, 10 -12,14,17,18 found in 50% of the cases. Other symptoms include cough, 5 dyspnea, 12 chest pain, 7 dysphagia, 5 back pain, 16 and hoarseness.…”

Bronchial artery aneurysm (BAA) is a rare entity. Ruptured BAA can cause life-threatening hemorrhage. It is recommended that treatment should be initiated immediately after diagnosis. We present the case of a 56-year-old female with multiple BAAs and interstitial lung disease. Aortic computed tomography angiography demonstrated that the largest aneurysm at the right hilum was fed by right subclavian artery and right bronchial artery. A fistula between the pulmonary trunk and the aneurysm was also revealed. The patient underwent transcatheter embolization. Coils were placed in the feeding vessels instead of the aneurysms to avoid nontarget embolization of the pulmonary arteries through the fistula. The procedure achieved reduction in aneurysmal blood flow. The patient’s cough resolved at 6-month follow-up.
