Bronchial artery aneurysm (BAA) is a rare entity that requires early diagnosis and immediate treatment due to the possibility of a life-threatening massive hemorrhage through rupture. The standard treatment is a surgical resection of the aneurismal artery. However, various embolization techniques, including coil embolization, are currently used as the optimal treatment because they are less invasive. A 65-year-old woman was referred for the treatment of intermittent hemoptysis. A chest CT scan showed an approximately 2 cm sized vascular mass with strong contrast enhancement originating from the right bronchial artery on the bronchiectatic parenchyma. On the angiogram, the inferior portion of the bronchial artery with a hypertrophic aspect and a huge bronchial artery aneurysm was detected on the left side branch. The bronchial artery aneurysm was embolized successfully with coils at the proximal and distal portion of the aneurysm. After coil embolization, the selective bronchial angiogram confirmed complete occlusion. We report this case of a bronchial artery aneurysm that was treated successfully with coil embolization.

Spontaneous bleeding due to vascular involvement of neurofibromatosis type 1 is rare but potentially fatal. Herein, we report a case of a lethal spontaneous hemomediastinum in a patient with neurofibromatosis type 1. The bleeding was caused by rupture of an aberrant bronchial artery arising from the ipsilateral subclavian artery, which was successfully treated using transarterial embolization with coils and N-butyl-2-cyanoacrylate.

Background: Massive hemoptysis is a major clinical and surgical problem related to high motality. Bronchial and nonbronchial systemic arteries are considered to be the main source of hemoptysis. Embolization of these arteries has become an accepted treatment in the management of massive hemoptysis. Herein we evaluate the effect of arterial embolization in immediate control of massive hemoptysis and investigate the clinical and angiographic characteristics and the course of patients with recurrent hemoptysis after initial successful embolization. Method: 21 patients (15 men & women, aged 21 to 74 years) underwent transcatheter arterial embolization for the treatment of life-threatening massive hemoptysis from Jan 1988 to July 1991. Seven patients had inactive residual pulmonary tuberculosis, 5 cases aspergilloma, 4 cases active pulmonary tuberculosis, 3 cases bronchiectasis and 2 case lung cancer. Arteriography was done by percutaneous catheterization via the femoral artery, and at the same time, arterial embolization was done with gelfoam particle. Result: Immediate control of massive hemoptysis was achieved in all 21 cases by arterial embolization. Hemoptysis recurred in nine of 21 patients. Four cases were aspergilloma, two inactive tuberculosis, two lung cancer, and one bronchiectasis. The initial angiographic findings revealed that nonbronchial systemic arterial supply, bronchial-pulmonary arterial shunt, and marked vascularity were more frequently, but statistically insignificant, in recurred patients. The following complications occured: fever, chest pain, cough, voiding difficulty, paralytic ileus, paraplegia, and splenic infarction. The course of the recurred patients was as follows: Three patients were died due to recurred massive hemoptysis. one was aspergilloma and two lung cancer. Surgical resection could be performed successfully in two patient with relatively good lung function, one aspergilloma and the other inactive tuberculosis. In 4 patients with poor lung function, repeated embolization or medical conservative treatment was continued. Conclusion: Arterial embolization as initial treatment of massive hemoptysis is most useful and relatively safe, although this is a palliative procedure and the potentiality for recurrence exists. Repeated embolization in inoperable patient with recurrent bleeding may improve the lengthening of life.

Systemic arterialization of lung with/without sequestration (Sequestration/Anomalous Origin of Left Pulmonary Artery, AOLPA) is a rare form of congenital anomalous systemic arterial supply to the lungs. In this anomaly, the arterial supply of one or more arteries of the basal segments of the lower lobe derives from an aberrant vessel arising from the aorta. We report two adult cases of systemic arterialization of normal basal segments of left lower lobe lung with/without sequestration. The one (AOLPA) was treated by left lower basal segmentectomy and the other (Sequestration) by therapeutic angiographic embolization. Based on the favorable follow-up result in our patients, although lobectomy (segmentectomy) is the basic treatment modality, embolotherapy could also be a mode of treatment that could be selectively applied to elderly, infirm patients or high risk patients with poor pulmonary function.

Background: Massive hemoptysis is a major clinical problem with high mortality. Bronchial artery embolization is well accepted and widely used for treatment of massive and recurrent hemoptysis, especially in patients with chronic diffuse pulmonary disease who are poor candidates for surgery. We evaluated the therapeutic effect of transcatheter arterial embolization for immediate control and prevention of recurrent hemoptysis. Method: We reviewed 20 cases(M:F=13:7) of bronchial artery embolization for the management of massive hemoptysis from Jun 1989 to Aug 1992 retrospectively. Results: Underlying causes of hemoptysis were pulmonary tuberculosis(n=14), bronchiectasis(n=3), aspergilloma(n=2) and paragonimiasis(n=1). Embolization material was choosed randomly gelfoam(n=7) or Ivalon(n=11) and in 2 cases both were used simultaneously. Target arteries of embolization were bronchial artery only in 15 cases, non-bronchial systemic arteries with or without bronchial artery in 5 cases. After the arterial embolization, immediate cessation of hemoptysis was achieved in 17 cases(85%) and total recurrence rate including 3 cases of immediate treatment failure was 50%. Among recurrences 3 cases were achieved lobectomy, 1 case was expired by asphyxia due to massive hemoptysis and remained 6 were managed by medical conservative treatment with no further recurrence of hemoptysis during follow up periods. Conclusion: Bronchial artery embolization for treatment of massive or recurrent hemoptysis was effective in immediate bleeding control. Despite high recurrence rate the rebleeding after embolization was less severe and controllable by conservative management. Bronchial artery embolization is valuable as primary trial to massive hemoptysis.

We report a case of mature cystic teratoma of the anterior mediastinum that ruptured into the pulmonary artery requiring an emergent surgical treatment. A 39-year-old woman presented an episode of massive hemoptysis and treated with bronchial artery embolization (BAE). On the 10th day after BAE, however, she developed sudden massive hemoptysis and had a deteriorated mental status. For a definitive treatment, she underwent the left pneumonectomy and the tumor resection in the anterior mediastinum. On histologic examination, the tumor disclosed cystic structures composed of mature squamous epithelium, pilosebaceous glands, mature fat tissue, cartilage and bone tissue. Also, there was intrapulmonary hemorrhage due to left pulmonary artery invasion of the tumor.

Hemoptysis which is comparatively common symptom in respiratory disease patients is a clinical symptom which has high risk of death in spite of many curative means. Bronchial tube embolization is a very useful medical procedure when hemoptysis does not stop for treatment of internal medicine or surgery and in addition to the purpose of instant hemostasis, for patients for whom surgical operation is impossible or for the purpose of gaining time to improve the state of the patient before surgical operation. In relation to this, this study is to know of the usefulness of bronchial tube artery embolization. The objects were 60 persons for whom bronchial tube artery embolizations are conducted because of large hemoptysis occurred from March 2007 to December 2009 in J hospital. They had large hemoptysis of 400ml or more per day and 200ml or more at a time or though the quantity of hemoptysis was less than 400ml they did not respond to the treatment of internal medicine for 10 days or longer. The average age was 60.5 years and cause diseases were tuberculosis, bronchiectasis, and pneumonia and lung cancer. Embolus parts were Rt bronchial artery 19 examples, Lt bronchial artery, both bronchial artery, Rt Intercostobronchial artery, and they were the case where embolization for many blood vessels were simultaneously carried out. As embolus materials, PVA (conteour) and microcoil were used. In 76.6% of 60 persons of patients hemorrhage stopped with the lapse of time after the procedure and in 4 examples (6.6) re-embolization was carried out due to re-bleeding after the procedure. Bronchial tube artery embolization has high early success rate and effectively controls hemoptysis in the treatment of hemoptysis and is an effective emergency remedy for hemorrhage due to large hemoptysis and will be a good medical procedure which reduces death rate. In addition, primarily if it is conducted together with the treatment of internal medicine it will be, as an effective curative means for hemorrhage due to large hemoptysis, a good mediate radial rays medical procedure which reduces death rate.

Bronchial artery aneurysm (BAA) is a rare disease, and multiple aneurysms of a single bronchial artery are rarer. Regardless of the size of the lesion, it is at risk of rupture and can cause massive hemoptysis or severe pain. We report a rare case of bronchial artery embolization (BAE) of multiple aneurysms of a single bronchial artery. During medical examination, a 64-year-old female was diagnosed with multiple BAAs and endobronchial lesions in the right lower lung on CT 10 years prior to presentation to our hospital. Further evaluation of the lesions was recommended; however, the patient was lost to follow-up. The patient complained of dyspnea and visited our hospital, and the size of the BAA had increased on CT. BAE was done successfully using N-butyl-2-cyanoacrylate and detachable coils. Follow up CT after BAE showed significant decrease in extent of inflammatory lesion in the right lung.

A 42 year-old male with a history of multidrug-resistant pulmonary tuberculosis suddenly developed massive hemoptysis. Embolization of a bronchial artery branch and the collateral systemic arteries did not resolve the recurrent bleeding. Spiral computerized tomography(spiral CT) of the chest showed contrast enhanced nodules within a large cavity at the left lower lobe in the arterial phase suggesting a Rasmussen aneurysm. A pulmonary angiogram showed abnormal vascular nodules at that site. Coils were deployed at both the proximal and distal vessels of this aneurysmal sac for embolization. Transcatheter arterial embolization is a safe and effective means of controlling bleeding from this pulmonary arterial pseudoaneurysm. Here we report a case of a Rasmussen aneurysm diagnosed by spiral CT, which was successfully treated by pulmonary arterial embolization with a coil.

Massive and untreated hemoptysis is associated with a mortality of greater than 50 percents. Since the bleeding was from a bronchial arterial source in the vast majority of patients, embolization of the bronchial arteries has become an accepted treatment in the management of massive hemoptysis because it achieves immediate control of the patients. We have controlled massive hemoptysis in a case with selective bronchial arteral embolization with Gelfoam.
