Bronchial artery aneurysm is a rare entity, detected in less than 1% of all patients undergoing selective bronchial arteriograms. Approximately 50 cases have been reported so far. Computed tomography (CT) reports of mediastinal bronchial artery aneurysms are rare. We report a case of a bronchial artery aneurysm in an 84-year-old male patient, which had been misdiagnosed as lung cancer for 6 years.

Background: Hemoptysis is one of the major symptoms in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD). However, its prevalence, incidence, and impact on long-term prognosis remain uncertain. We evaluated the incidence of clinically significant hemoptysis, and determined its association with mortality in patients with NTM-PD.

Adenosine is extensively utilized in myocardial stress perfusion imaging for the detection and risk stratification of coronary artery disease. It has a well-established safety profile. The majority of the undesirable effects experienced during adenosine infusion are transient (owing to its brief half-life of ~10 s) and arise from the stimulation of receptors in the atrio-ventricular (AV) node (AV block) and bronchial smooth muscles (bronchospasm).

Ann Thorac Surg Short Rep
September 2024
Department of Pediatric Cardiovascular Surgery, Kanazawa Medical University, Ishikawaken, Japan.
Background: The study focuses on vascular compression of the main bronchus in the aortopulmonary space, examining potential contributors within the same axial plane. Its goal is to uncover mechanisms of bronchial compression in patients with intracardiac anomalies and review surgical outcomes, aiming to enhance future results.
Methods: The morphology and topology of structures within the axial plane of the aortopulmonary space were objectively analyzed, including the sternum, ascending aorta, heart, pulmonary artery, descending aorta, and other relevant elements.

Department of Surgery II, Faculty of Medicine, Yamagata University, Yamagata, Japan.
Background: With advancements in minimally invasive thoracic surgery techniques, such as video-assisted thoracoscopic surgery and robotic surgery, the design of vascular staplers has evolved to meet the requirements of these procedures. Consequently, newer generations of automatic staplers with improved handling and reduced size have been introduced, such as two-row staplers, which are more maneuverable and less bulky than their three-row counterparts.
Case Presentation: A 68-year-old man with lung cancer underwent a right middle and lower lobectomy due to tumor invasion into the central middle bronchial trunk, rendering the preservation of the middle lobe impossible.
Endovascular interventions in cancer patients with compromise of the mediastinal vasculature: a review.

The mediastinal vasculature can be affected by various etiologies in cancer patients. Both direct and indirect sequela of cancer may result in life-threatening clinical presentations. Tumor growth may cause vessel narrowing and decreased blood flow from either extrinsic mass effect, invasion into the vascular wall, or tumor thrombus within the lumen.
