A 58-year-old female patient presented to the hospital with hearing loss. In the chest radiography obtained before her ear surgery, volume decrease in the right hemithorax, elevation of the right diaphragm, and increase of ventilation in the right lung were detected. At the thorax CT-CT angiography, hypoplasia of the main pulmonary artery and its branches and arteriovenous malformation localized in the middle lobe of the right lung were detected. Thus, diagnosis of Swyer-James-Macleod syndrome associated with right lung middle lobe hypoplasia and arteriovenous malformation was made. This kind of association has not been reported earlier, so we are presenting it in the light of the literature knowledge.

Morphometic data of the pulmonary artery in the cat’s right lung are presented. Silicone elastomer casts of cat’s right lung were made, and measured, counted and analyzed. The Strahler system is used to describe the branching pattern of the arterial vascular tree. These data are needed for any quantitative approach to the study of the pulmonary circulation. For all the pulmonary blood vessels of the cat lying between the main pulmonary artery and the capillary beds, there are a total of 10 orders of vessels in the right upper lobe, 9 orders of vessels in the right middle lobe and 11 orders of vessels in the right lower lobe. The ratio of the number of branches in successive orders of vessels or the branching ratio, is 3.58. The corresponding average diameter ratio is 1.72, whereas the average length ratio is 1.81.

Abstract Background Mediastinal branching of the A7a from the right main pulmonary artery (PA) is extremely rare. Herein, we report a patient with an aberrant mediastinal A7a who underwent right basal segmentectomy for lung cancer. Case presentation A 73-year-old man was referred to our department for a right lower lobe nodule measuring 18 mm in diameter on computed tomography (CT). Three-dimensional (3D) CT revealed mediastinal A7a branching from the right main PA. As the patient had undergone colectomy for advanced ascending colon cancer, the nodule was suspected to be a metastasis from the colon primary, and thus, basal segmentectomy of the right lung was performed. Intraoperatively, the A7a was observed behind the V4+5 and middle lobe bronchus. The pathological diagnosis was combined small cell carcinoma with an adenocarcinoma component (p-T1cN0M0, stage IA3). The patient subsequently received adjuvant chemotherapy for colon cancer. At 1-year postoperative follow-up, there was no evidence of disease. Conclusion This is the first report describing an aberrant mediastinal A7a branching from the right main PA. It is important to obtain accurate information about variations of the PA using 3D-CT for safe anatomical pulmonary resection.

A 38-year-old man with a history of polyposis syndrome diagnosed 3 years previously, with poor compliance for follow-up, presented to the emergency department with symptoms of retrosternal chest pain associated with dizziness and shortness of breath. His blood pressure was 94/43 mm Hg, his pulse was 123 beats/min and he had an oxygen saturation of 84% on room air. The patient’s initial laboratory results showed a hemoglobin of 80 g/L and blood gas with a pH of 7.23. He had a normal chest radiograph and electrocardiogram, but had an elevated troponin I at 0.12 μg/L. He was given acetylsalicylic acid for suspicion of acute coronary syndrome. On physical examination, the patient was found to have right calf tenderness. With this finding and the presenting symptoms, he underwent computed tomography angiography (CTA) of the chest. The chest CTA showed a massive saddle embolus with a filling defect completely occluding the right pulmonary artery and extending through the main pulmonary artery segment to involve the left pulmonary artery. There were also diffuse filling defects involving bilateral pulmonary segmental arteries (Fig. 1 and Fig. 2). The patient received alteplase and underwent a workup for a hypercoagulable state. His workup revealed positive anticardiolipin antibodies and factor V Leiden. The Doppler ultrasound of his lower extremities showed an extensive thrombus measuring more than 6 cm extending in the right superficial femoral vein. The patient was then referred for placement of an inferior vena cava filter.

Abstract Introduction Inflammatory myofibroblastic tumor (IMT), also known as plasma granuloma, is a very rare tumor with varying biological behavior, from completely benign to malignant. IMT can occur in virtually every organ, but cardiac origin is extremely rare. IMT occurs mainly in children and young people. The mainstay of treatment is complete surgical resection of the tumor. We present a case of 28 year old white woman with no contributory medical and family history, who was admitted to hospital because of dyspnea and cough. The transthoracic echocardiography (TTE) showed elevated pulmonary artery systolic pressure up to 61 mm Hg and mild dilation of right chambers. Further assessment by computed tomography showed thrombosis of the main pulmonary artery (PA), narrowing its lumen by 90%, with spread to the lobar and segmental arteries of the left lung - signs of massive pulmonary embolism. During thromboendarterectomy revealed a mass, about 4,1 x 3,1 x 1,8 cm in size, with thrombotic overlays, locating at the right ventricular outflow tract (RVOT) and the pulmonary trunk. Histological examination and Immunohistochemistry studies was consistent with IMT with an intermediate potential of malignancy. A year after the operation, the patient became pregnant. Routine TTE showed low density mobile mass narrowing the pulmonary trunk. The transvalvular blood flow velocity was 2.4 m/s. Cardiac magnetic resonance (CMR) was consistent with echo findings. The pregnancy has been preserved, and after 36 weeks it was decided to perform the birth of a girl by means of a Cesarian section. After 2 months, due to an increase in the size of the tumor and the dyspnea, a reoperation was performed to remove the tumor lining the RVOT and intimately connected with the PA valve, excision of the PA valve. A bioprosthesis was installed. The tumor had an identical morphological picture. Conclusion This case report describes a rare recurrent cardiac inflammatory myofibroblastic tumor involving RVOT and PA. The prognosis after surgical treatment of IMT is usually favorable, but it is known that some tumors recur, and rarely they can even metastasize. The long-term outcome is not well established due to the rarity of these tumors. Abstract P1700 Figure.

AbstractTracheobronchial compression of cardiovascular origin is an uncommon and frequently unrecognised cause of respiratory distress in children. The compression may be due to encircling vessels or dilated neighbouring cardiovascular structures. Bronchoscopy and detailed radiography, especially computed tomography and magnetic resonance imaging, are among the most powerful diagnostic tools. Few previous reports have addressed the relationship between bronchoscopic findings and underlying cardiovascular anomalies. The objective of this study was to correlate bronchoscopic and radiographic findings in children with cardiovascular-associated airway obstruction. A total of 41 patients were recruited for the study. Patients with airway obstruction were stratified on the basis of the aetiology of the cardiovascular structures and haemodynamics into an anatomy-associated group and a haemodynamics-associated group. In the anatomy-associated group, stenosis and malacia were found with comparable frequency on bronchoscopy, and the airway obstructions were mostly found in the trachea (71% of patients). In the haemodynamics-associated group, malacia was the most common bronchoscopic finding (85% of patients), and nearly all locations of airway involvement were in the airway below the carina (90% of patients). The tracheal compression was usually caused by aberrant systemic branching arteries in the anatomy-associated group. In the haemodynamics-associated group, the causal relationships varied. Tracheal compression was often caused by lesions of the main pulmonary artery and aorta, whereas obstruction of the right main bronchus was caused by lesions of the main pulmonary artery and right pulmonary artery. The causes of left main bronchus compression were more diverse. In summary, the bronchoscopic presentations and locations are quite different between these two groups.
