The bronchial artery-pulmonary vein malformation should be called the systemic artery-to-pulmonary vein arterioveonus malformation in the lung. Although pulmonary arteriovenous malformation has been well documented in intrapulmonary arteriovenous malformation, the systemic artery-to-pulmonary vein arteriovenous malformation is rare. Most patients with systemic artery-to-pulmonary vein arteriovenous malformation is asymptomatic and the diagnosis of these anomaly may be done by continuous murmur or abnormal chest X-ray on the physical examination. The pathogenesis of this condition is congenital malformation which explains these anastomoses between the pulmonary vein and accessory brachial arteries and acquired malformation which explains development of new blood vessel to supply large enough to cause significant systemic-pulmonary shunts due to inflammation secondary to infection, trauma, or previous surgery. We experienced a case of the bronchial artery-pulmonary vein malformation which was detected on angiography in 20-year-old women whose chief complain is hemoptysis. This massive hemoptysis was controlled by selective brachial artery embolization with Gelfoam and Ivalon particles.

Background : Bronchial artery embolization has been established as an effective means to control hemoptysis, especially in patients with decreased pulmonary function and those with advanced chronic obstructive pulmonary disease. We evaluated the effect of arterial embolization in immediate control of massive hemoptysis and investigated the clinical and angiographic characteristics and the course of patients with reccurrent hemoptysis after initial succeseful embolization. Another purpose of this study was to find predictive that cause rebleeding after bronchial artery embolization. Method : We reviewed 47 cases that underwent bronchial artery embolization for the management of massive hemoptysis, retrospectively. We analyzed angiographic findings in all cases before bronchial artery embolization and also reviewed the angiographic findings of patients that underwent additional bronchial artery embolization for the control of reccurrent hemoptysis to find the clauses of rebleeding. Results : 1) Underlying causes of hemoptysis were pulmonary tuberculosis(n=35), bronchiectasis(n=5), aspergilloma(n=2), lung cancer(n=2), pulmonary A-V malformation(n=1), and unknown cases(n=2). 2) Overal immediate success rate was 94%(n=44), an6 recurrence rate was 40%(n=19). 3) The prognostic factors such as bilaterality, systemic-pulmonary artery shunt, multiple feeding arteries and degree of neovascularity were not statistically correlated with rebleeding tendency (p value>0.05). 4) At additional bronchial artery embolization, Revealed recannalization of previous embolized arteries were 14/18cases(78%) and the presence of new deeding arteries was 8/18cases(44%). 5) The complications(31cases, 66%) such as fever, chest pain, cough, voiding difficulty, paralytic ileus, motor and sensory change of lower extremity, atelectasis and splenic infarction were occured. Conclusion : Recannalization of previous embolized arteries is the major cause of recurrence after bronchial artery embolization. Despite high recurrence rate of hemoptysis, bronchial artery embolization for management of massive hemoptysis is a effective and saute procedure in immediate bleeding control.

A 71-year-old male with known bronchiectasis and atrial fibrillation was admitted to Seoul St. Mary's Hospital with recurrent transient ischemic attack. R adiofrequency ablation was performed to resolve the patient's atrial fibrillation, but failed. However, a fistula between the left circumflex artery and the bilateral bronchial arteries was found on computed tomography. Fistula ligation and a left-side maze operation were planned due to his recurrent symptom of dizziness, and these procedures were successfully performed. After the operation, the fistula was completely divided and no recurrence of atrial fibrillation took place. A coronary-bronchial artery fistula is a rare anomaly, and can be safely treated by surgical repair.

Between January 1990 and June 1993, the retrospective analysis was done in 48 consecutive patients with hemoptysis. According to clinical condition of patients, managements were divided into 3 subgroups; group 1[percutaneous bronchial artery embolization, group 2[operation after percutaneous bronchial artery embolization],group 3[delayed and emergency operation]. It was characterized that recurrence of hemoptysis was very frequent and most frequent underlying cause was pulmonary tuberculosis. In 40 patients[83%] urgent examination with flexible broncoscope was done and localization of the bleeding source was possible only in 24[60%] patients. The amount of hemoptysis was variable but there are no difference between groups and 22 patients[45%] had a prior episode of hemoptysis usually within 3 months of their admission. The recurrence was limited only in group 1[3/22] and the mortality rate was 6%[3/48]. We suggest that percutaneus bronchial artery embolization may be effective in recurrent massive hemoptysis but definitive management was operation.

The anomalous systemic arterial supply to the lung without sequestration is an uncommon congenital anomaly characterized by the presence of a part of lung tissue which supplied by an aberrant artery from the aorta or its branch and normal communication with the normal bronchial tree, and it was reported by Huber in 1777 first. It differs from bronchopulmonary sequestration in having normal bronchial communication from the remainder lung and normal lung histology. We experienced a case of anomalous systemic arterial supply to the lung without sequestration, which was confirmed preoperatively. The patient was 16 year old male and came to us with complaints of mild fever and profuse sputum with coughing. Chest film showed a ring-like soft tissue shadow in Rt. middle lung field. Aortogram revealed an aberrant artery originated from abdominal aorta at 12th thoracic vertebral level and supplying a part of Rt. lower lobe of lung. At. the time of operation, an aberrant systemic artery which originated from the abdominal aorta supplying the Rt. lower lobe was noted, and the bronchial communications were normal. After division and ligation of the aberrant artery, Rt. lower lobectomy was performed The postoperative courses were uneventful and the patient was discharged with good condition.

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 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.

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.

Several stresses are known to induce synthesis of heat shock protein The present study was performed to see whether pulmonary ischemia, induced by the bronchial artery occlusion, produced HSP70 in cat lung. To This aim, we compared experimental and control groups of cats with respect to the HSP70 production in the lung. Experimental animals were subjected to 10-min bronchial artery occlusion followed by reperfusion. The interval between the end of the occlusion and the end of the reperfusion was 1 hour, 4 hours and 8 hours, whereas control animal was not subjected 10 any manipulation except anesthesia. According to the interval differences, experimental animals were divided into 1HR, 4HRs and 8HRs groups. To determine The induction of HSP70 in each group, total proteins of lung tissues were extracted and separated by PAGE electrophoresis. Immunoblotting with a mouse monoclonal anti -HSP70 IgG antibody revealed that HSP70 was not detected in the pulmonary tissues resected from control, 1HR or 4HRs groups. In contrast. HSP70 expression in 8HRs group was marked. These results suggest that pulmonary ischemia by the bronchial artery occlusion produces HSP70 in a delayed manner.

Systemic arterial supply from the descending thoracic aorta to the basal segment of the left lower lobe without a pulmonary arterial supply is a rare congenital anomaly within the spectrum of sequestration lung disease. The most common pattern of anomalous systemic artery to the lung arises from the descending thoracic aorta and feeds the basal segments of the left lower lobe. We report an extremely rare case of a 29-year-old woman who underwent a successful left upper lobectomy for the treatment of recurrent massive hemoptysis from anomalous bronchial arterial supply to the lingular segment of left upper lobe.
