Massive hemoptysis is a medical emergency and needs immediate treatment. It occurs in a wide variety of pulmonary diseases and typically originates from the bronchial arteries. We herein report a very rare case of a patient bleeding from a right phrenic artery-to-pulmonary artery fistula accompanied with focal bronchiectasis in the right middle lobe of the lung. In this case, multi-detector computed tomography was useful for clarifying the etiology and the abnormal anastomosis and facilitated effective angiographic embolization...

BACKGROUND: Pulmonary hypertension (PH) can be caused by a fistula between the systemic and pulmonary arteries. Here, we report a case of PH due to multiple fistulas between systemic arteries and the right pulmonary artery where the ventilation/perfusion scan showed no perfusion in the right lung. METHODS: A 32-year-old male patient was hospitalised for community-acquired pneumonia. After treatment with antibiotics, the pneumonia was alleviated but dyspnoea persisted...

A 69-year-old woman was referred to our hospital due to dyspnea on exertion and a heart murmur. A chest X-ray showed a bulge at the left 3rd arch and chest computed tomography( CT) revealed a giant mass adjacent to the right ventricular outflow. Multidetector-row CT and coronary angiography showed a giant coronary aneurysm (55×45 mm) and fistulae arising from the left main coronary trunk and entering into the main pulmonary artery (PA). The pulmonary to systemic flow ratio was 1.84. She was diagnosed with coronary-pulmonary artery fistulae with giant coronary aneurysm...

A coronary artery fistula is defined as an abnormal direct communication between any coronary artery and any of the cardiac chambers, superior vena cava, coronary sinus, pulmonary artery, and pulmonary veins. The right coronary artery (RCA) is the most common site of origin, and right heart chambers are the most common site of drainage. However, there are few cases reported in the literature in which the fistulae originate from both the right coronary and the left anterior descending arteries and drain into the pulmonary artery...

Bronchial artery aneurysm (BAA) is a rare vascular phenomenon. This review highlights a case of a BAA that was complicated by the presence of a bronchial artery to pulmonary artery (BA-PA) fistula, consequently presenting a unique challenge to management. BAAs have a strongly reported risk of rupture resulting in life-threatening hemoptysis. Embolization has thus become routine for the management such severe cases. The management of incidentally found anomalies is less obvious, but prophylactic embolization is a generally accepted practice...

We report a case of coronary-pulmonary artery fistula in a hemodialysis patient treated surgically. A 47-year-old man was admitted with chest pain and exertional dyspnea that progressively worsened over the previous 2 months. He had a history of end-stage renal disease and has been on hemodialysis for 5 years. Coronary angiography and computed tomography revealed coronary-pulmonary artery fistula that originated from both the left anterior descending coronary artery and the right coronary artery. Under cardiopulmonary bypass, we opened the pulmonary artery and closed the fistula...

Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe...

We report the case of an 11-year-old girl with heterotaxy syndrome, dextrocardia, and azygos continuation of an interrupted inferior vena cava who had developed pulmonary arteriovenous fistulas after a Kawashima procedure consisting of bilateral superior cavopulmonary anastomoses. She presented with profound cyanosis, fatigue, and failure to thrive. An operative procedure to direct hepatic vein effluent to the pulmonary circulation was performed with placement of an extracardiac conduit between the hepatic veins and the left pulmonary artery...

We report the imaging findings of an uncommon coronary vascular termination anomaly, with fistula to the pulmonary artery. This 70 year old female patient presented unstable angina, showing a coronary artery fistula depicted in coronary angiogram from the left coronary to the pulmonary artery, with no significant atherosclerotic pathology. Due to development of ventricular tachycardia in stress echocardiogram examination, she was proposed for coronary fistula closure. Coronary CT was performed for procedure planning and allowed the identification of a second unsuspected fistula from the right coronary to the right pulmonary artery...

Chih-Hsin Hsu, Jun-Neng Roan, Jyh-Hong Chen, Chen-Fuh Lam
The presence of systemic left-to-right shunt and increased pulmonary blood flow can result in right heart failure and pulmonary arteriopathy. Correction of left-to-right shunt has been shown to improve cardiac function and physical performance. However, the cardiopulmonary remodeling processes following cessation of left-to-right shunt have yet to be reported. In this experimental study, excessive pulmonary flow was restored through ligation of the aortocaval fistula in rats with flow-induced pulmonary hypertension...

Bronchial artery embolization is now a common treatment for massive pulmonary hemoptysis if flexible bronchoscopy at the bedside failed to control the bleeding. Complications of this technique range from benign chest pain to devastating neurological impairments. We report the case of a 41-year-old man who developed an ST elevation myocardial infarction during bronchial artery embolization, presumably because of coronary embolism by injected particles. In this patient who had no previously known coronary artery disease, we retrospectively found a communication between the left bronchial artery and the circumflex coronary artery...
