A 27-year-old man was admitted to hospital for the investigation of hemosputum. He is a serving member of the Japan Self-Defense Forces. Chest radiography showed absence of the right hilar component, and the ipsilateral hemithorax was smaller than that of on the left side. Pulmonary arteriography demonstrated complete absence of the right pulmonary artery. Right cardiac catheterization did not show any concomitant cardio-vascular malformation. Therefore, this case was diagnosed as an isolated absence of the right pulmonary artery. Bronchial arteriograms demonstrated showed vascular enlargement and proliferation of the right bronchial artery. Bronchofiberscopic examination showed obvious bronchial mucosal vascular enlargement with submucosal eruption and swelling of the right bronchi. We also re-examined the chest radiographs of this patient from the previous 9-years. Those revealed a chronological decrease of the right lung volume and an increase of the cardio-thoracic ratio. Isolated absence of the right pulmonary artery is generally considered to have preferable survival, but close observation is necessary to monitor the pulmonary hemodynamics. 相似文献

A 40-year-old woman was admitted to our hospital for investigation of an abnormal chest roentgenogram. She had been well with normal exercise tolerance and had no history of pneumonia. The chest roentgenogram showed decreased vascularity of the right lung, ipsilateral small hemithorax, and shift of the mediastinum toward the right. In the right lung field, hazy and confluent micronodular shadows were seen, and the left lung was emphysematous and hyperlucent. Herniation of the left lung into the contralateral thorax was seen. Although lung perfusion scintigrams showed no detectable blood flow to the right lung, a krypton ventilation study revealed diminished but homogeneous ventilation of the ipsilateral lung. A bronchogram showed normal structure of the bronchi. Cardiac catheterization revealed normal pulmonary arterial pressure. A pulmonary angiogram showed no right pulmonary artery, and absence of other cardiovascular anomalies. Therefore, the diagnosis of isolated absence of the right pulmonary artery was confirmed. An aortic angiogram demonstrated collateral vessels originating from one of the bronchial arteries, the infradiaphragmatic artery, and the right coronary artery. Chest CT disclosed cystic changes in the right lung field. 相似文献

Idiopathic dilatation of the pulmonary artery (IDPA) is a rare anomaly presenting with enlargement of the pulmonary artery in the absence of an identifiable cause. The natural history of this silent but potentially life‐threatening disease can be unpredictable. We report a case of IDPA in an 80‐year‐old female with a massively dilated pulmonary artery. 相似文献

Hemoptysis was the presenting symptom in a 4-year, 11-month-old male who had had a Mustard operation for hemodynamic correction of transposition of the great vessels at the age of five months. Chest roentgenography demonstrated hyperlucency of the left lung and tomography showed compression and narrowing of left main stem bronchus. Angiography documented the absence of antegrade flow in the left pulmonary artery and no pulmonary venous drainage on the left. The left lung was supplied by bronchial collateral arteries which drained by retrograde filling of the left pulmonary artery. It is surmised that pulmonary venous drainage on the left was compromised at surgery and that the dilated main pulmonary artery compressed the left main stem bronchus. This combination promoted bronchial collateral ingrowth. Hemoptysis is a complication of enlargement of bronchial collateral vessels. 相似文献

Unilateral absence of the pulmonary artery (UAPA) is a rare congenital cardiovascular malformation that can present as an isolated lesion or may be associated with other congenital heart malformations. Several studies have reported UAPA after birth. To our knowledge, the absence of the right pulmonary artery in the fetus has not been reported. Here, we report a rare case of fetal right pulmonary artery absence with aortic coarctation, which was confirmed by postpartum ultrasound and computed tomography angiography (CTA). Our case demonstrates that fetal echocardiography, especially the three‐vessel view, is beneficial for the prenatal diagnosis of pulmonary artery malformations. 相似文献

A seven-month-old girl, born prematurely (birth weight 1000 g) from a twin pregnancy, was admitted to hospital due to recurrent pneumonia and atelectasis. She experienced cough and respiratory distress during feeding. The right hemithorax was smaller than the left, with diminished breath sounds and dullness. Chest x-rays revealed decreased lung volume and multiple radiolucent images in the right lung, as well as overdistention of the left lung. An esophagogram revealed three bronchial branches arising from the lower one-third of the esophagus, corresponding to the right lung and ending in a cul-de-sac. A diagnosis of esophageal lung was established. On bronchography, the right lung was absent and the trachea only continued into the left main bronchus. Echocardiography and angiotomography revealed agenesis of the pulmonary artery right branch. The surgical finding was an esophageal right lung, which was removed; the histopathological diagnosis was type II congenital pulmonary airway malformation in an esophageal lung. 相似文献

We describe the imaging features of a 48‐year‐old woman with primary sarcomatoid carcinoma originating from right ventricular outflow tract (RVOT) and isolated absence of right pulmonary artery (RPA). Computed tomography pulmonary angiography (CTPA) demonstrated the absence of RPA. Both transthoracic echocardiography (TTE) and CTPA revealed multiple masses filling and obstructing the RVOT. A palliative operation was performed on the patient, and the postoperative histopathology and immunohistochemical examination confirmed primary sarcomatoid carcinoma originating from the RVOT. The operation also confirmed the absence of RPA. 相似文献

The case of a patient with pulmonary veno-occlusive disease associated with systemic sclerosis is reported. The patient presented with progressive dyspnoea. Echocardiography and cardiac catheterization study demonstrated right-sided heart failure. The CXR suggested pulmonary hypertension and interstitial pulmonary oedema. We suspected pulmonary veno-occlusive disease based on radiological and haemodynamic findings. Treatment with prednisolone resulted in a reduction in pulmonary arterial pressure and CXR findings improved 2 months later, but no further effect was observed. The patient died 7 months later and at autopsy the lungs showed prominent thickening of the interlobular septa and small branches of pulmonary veins showed intimal thickening. 相似文献

A 29-year-old woman was admitted to our hospital because of hemoptysis and dyspnea. A chest radiographic study revealed an enlargement of the right lung hilum, and the left pulmonary artery could not be clearly visualized on contrast-enhanced CT scan. Both perfusion scintigraphy and pulmonary angiography confirmed the absence of the left pulmonary artery, and agenesis of the right upper pulmonary artery. Her clinical status has been stable for the previous two years of follow-up, even though she required long-term oxygen therapy. This is a rare case of a young woman with the unilateral absence of the left pulmonary artery incidentally found after an episode of hemoptysis. 相似文献

A 33-year-old man was investigated for dyspnea on exertion and the presence of a pansystolic murmur. Physical examination revealed dextrocardia confirmed by chest radiograph, which also showed oligemic right lung field. Subsequent cardiac catheterization revealed secundum atrial septal defect, persistent left sided superior vena cava, and severe mitral valve prolapse causing severe mitral regurgitation with pulmonary hypertension. The right pulmonary artery was absent. It is the first report of the association between severe mitral valve prolapse and absent right pulmonary artery. 相似文献

目的通过探讨红细胞分布宽度(RDW)与简化肺栓塞严重指数(s PESI)的关系来预测急性肺栓塞危险程度。方法将90例急性肺栓塞患者分为s PESI低危组和高危组,比较两组患者在基本资料、血常规、凝血功能、肝肾功能、胸部影像学及心脏彩超等方面的差异。结果 s PESI高危组与低危组比较,在心率、收缩压、凝血酶原时间、国际标准化比值、中性粒细胞、RDW、累及主肺动脉及右心室增大等方面,差异有统计学意义(P0.05);logistic单因素回归分析发现收缩压、INR、RDW、累及主肺动脉、右心室增大与s PESI分组有关(P0.05);logistic多因素回归分析发现累及主肺动脉是影响s PESI分组的独立危险因素(P0.05)。结论 RDW在s PESI高危组与低危组差异有显著性,但不是预测s PESI分组的独立危险因素,对急性肺栓塞危险程度的判断有一定价值。 相似文献

Case. A 54-year old woman was found to have an abnormal shadow in a regular checkup chest X-ray film. We suspected a bronchial artery aneurysm based on a contrast-enhanced chest CT. Aortography, bronchial arteriography and pulmonary arteriography showed a bronchial artery aneurysm, 2 cm in diameter, connecting the right bronchial artery, inferior phrenic artery, and pulmonary artery. Bronchoscopy revealed dilatation and hypervascularity of moniliform submucosal vessels below the right truncus intermedius. She underwent bronchial artery embolization several times, but new feeding vessels developed each time. We considered this case required surgical resection. Bronchoscopy after aneurysmectomy revealed decrease of moniliform submucosal vessels. Histological examination revealed a three-layer structure leading to both the pulmonary and bronchial arteries. Conclusion. We diagnosed idiopathic bronchial artery aneurysm connecting to a pulmonary artery. 相似文献

We report a case of racemose hemangioma of the right bronchial artery complicated with an atrial septal defect (ASD) and ground-glass opacity localized in the right upper lung lobe. A 42-year-old woman was admitted for the pre-operative assessment of ASD. Aortography and selective angiography revealed that the right bronchial artery was markedly dilated and convoluted, draining into the right intercostal arteries and the right upper pulmonary vein. The patient was suffering from exertional dyspnea, but produced no bloody sputum. Since videobronchoscopy showed normal mucosal findings without bronchiectasis, primary racemose hemangioma of the right bronchial artery was diagnosed, and was treated by ligation of the bronchial artery and patch-closure of the ASD. The ground-glass opacity observed preoperatively in the periphery of the right upper lung lobe vanished after surgery. This opacity was considered to have been localized pulmonary congestion due to augmented hydrostatic pressure in the right upper pulmonary vein, induced by increased pulmonary blood flow through the ASD and the drainage route of the racemose bronchial artery into right upper pulmonary vein. 相似文献

Occlusion of the pulmonary artery is a rare complication of mediastinal tuberculosis. We report on a 10-year-old girl who presented with a tuberculous pericardial effusion in whom subsequent imaging showed a totally occluded right pulmonary artery from tuberculous lymphadenopathy. Diagnosis was confirmed by polymerase chain reaction from a lymph node biopsy. Failure of medical therapy necessitated surgical reconstruction of her right pulmonary artery. Postoperatively she has normal perfusion of the right lung and normal lung function. 相似文献
