Objective To evaluate the clinical effects of bronchial artery embolization ( BAE) for massive hemoptysis due to bronchiectasis.Methods 205 patients with massive hemoptysis were treated with bronchial artery embolization using coils, polyvinyl alcohol ( PVA) microspheres, line segmen, and gelatin sponge after the site of bleeding or the abnormal arteries were identified by arteriography. Super selective bronchial artery embolization was performed with a coaxial microcatheter inserted into the bronchial artery. Results BAE was successfully performed in 205 cases with massive hemoptysis ( left and right bronchial artery embolization in 35 cases, left bronchial artery embolization in 20 cases, right bronchial artery embolization in 126 cases, common bronchial artery embolization in 22 cases, right inferior phrenic artery embolization in 2 cases) . Of 205 patients, 169 were cured, 24 were relieved with a success rate of 94.1% . Long termcumulative hemoptysis nonrecurrence rates was 82.4% . 23 patients developed post embolization syndrome characterized by mild fever and chest pain and ended with spontaneous recovery without special management. No severe complications including spinal cord injury or dystopia embolization were observed. Conclusions Bronchial arterial embolization interventional therapy is a rapid, safe and effective method in the treatment of massive hemoptysis due to bronchiectasis.
Objective To summarize the diagnosis and treatment of spontaneous rupture of bronchial artery aneurysm in mediastinum.Methods Two cases diagnosed as bronchial artery aneurysmby methods of enhanced-CT plus independent post-procedure techniques and bronchial artery selective angiography were cured by different intervention surgeries in our hospital. The clinical data of these two patients and different interventional treatments were summarized.Results Case 1 was a 38-year old male.He was given coils and PVC micro-particles, and bronchial artery selective angiography showed distal vascular occlusion and aneurysmsize decreased. Case 2 was a 59-year old female. She was also given coils, but digital subtraction angiography showed bleeding of bronchial artery whose opening was near to the aorta.Then a stent was implanted in the descending aorta to isolate the bleeding bronchial artery, and bronchial artery selective angiography showed blood flow was completely blocked. Conclusions Enhanced-CT plus vascular three-dimensional reconstruction and bronchial artery selective angiography is a chief method to diagnose bronchial artery aneurysm. Bronchial artery embolization and/ or isolating surgery with covered stent are minimally invasive, efficient, trustworthy treatment for spontaneous rupture of bronchial-artery aneurysmin mediastinum. Different techniques of interventional treatment are selected depending on lesion.
