BACKGROUND: Bronchial artery aneurysm (BAA) is an uncommon but potentially life-threatening disease, and multiple BAAs are even rarer. Clinically, the tortuous and short neck of a BAA may present significant challenges for invasive intervention. METHODS: This report describes the detailed process of diagnosis and treatment and includes a literature review of the etiology, clinical presentation, and therapeutic management of BAA. RESULTS: A rare case of multiple BAAs, with one having an inflow artery arising from the brachiocephalic trunk, was referred to our hospital...

We present the case of a 50-year-old man with Cushing syndrome caused by an ectopic adrenocorticotropic hormone (ACTH)-secreting tumor. A small nodule was located in close association with the lateral segmental branch of the pulmonary artery in the left upper lobe. Blood samples were obtained from various branches of the pulmonary artery by balloon-occluded retrograde sampling for the measurement of location-specific serum ACTH levels. After confirmation that the pulmonary nodule was responsible for the increased ACTH secretion, lobectomy was performed...

Bronchial artery aneurysm (BAA) is an uncommon disease, and spontaneous rupture of an ectopic BAA can be difficult for diagnosis and life-threatening. This case study describes a 52-year-old man who presented with acute onset of right chest pain, mild tachycardia, and hypertension. The initial diagnosis of acute myocardial infarction was made, and the patient was given nitroglycerin prior to admission to our hospital. However, the patient's symptoms deteriorated. An enhanced computed tomography scan revealed a ruptured 25-mm diameter mediastinal aneurysm under the tracheal bifurcation when he was admitted to our hospital...

Mujtaba Ali, David A Kumpe
Ectopic parathyroid adenomas in the aortopulmonary window (APW) are extremely rare, constituting only 1% of ectopic mediastinal adenomas and 0.24% of all parathyroid adenomas. The authors have encountered three patients with ectopic adenomas in the APW. In each case, the primary arterial supply to the APW adenoma arose from the bronchial artery. In addition, there was a small anastomotic arterial channel connecting the bronchial artery supplying the adenoma to the left inferior thyroid. All three adenomas were treated with transcatheter embolization, with control of hyperparathyroidism in two of three patients...

A 4-year-old boy presented with pneumonia. Computed tomography demonstrated a multicystic mass at the posteromedial bilateral lower lobe segments, which were connected by a bronchus behind the heart. Enhanced computed tomography revealed that an anomalous artery arose from the left gastric artery and inserted into the left sequestrated lung and branched to the right one. The diagnosis of bilateral intralobar sequestration (ILS) with a bridging isthmus was made. After removal of the bilateral ILS, radiologic and pathologic approaches were undertaken to reconstruct the vascular and bronchial architectures...

Life-threatening hemoptysis is a severe condition that requires rapid diagnosis and treatment. One of the treatments of choice is embolization. The initial assessment aims to locate the origin and cause of bleeding. The technological advance of the development of multidetector computed tomography (MDCT) has changed the management of patients with life-threatening hemoptysis. MDCT angiography makes it possible to evaluate the cause of bleeding and locate the vessels involved both rapidly and noninvasively; it is particularly useful for detecting ectopic bronchial arteries, nonbronchial systemic arteries, and pulmonary pseudoaneurysms...

Bronchial arteries arise normally directly from the descending thoracic aorta, at the level between the fourth and sixth thoracic vertebra. However the anatomical variations are very frequent regarding the origin or the number of branches. We present a rare cadaveric finding of an ectopic right bronchial artery originating from the right subclavian artery through common stem with the right internal thoracic artery and we discuss the clinical significance of this finding. A 72-year-old formalin-embalmed male cadaver was dissected during a routine anatomical course...

OBJECTIVE: Resistin-like molecule (RELM) β is a secretory protein homologous to resistin and reportedly contributes to local immune response regulation in gut and bronchial epithelial cells. However, we found that activated macrophages also express RELMβ and thus investigated the role of RELMβ in the development of atherosclerosis. APPROACH AND RESULTS: It was demonstrated that foam cells in atherosclerotic lesions of the human coronary artery abundantly express RELMβ...

Clenbuterol is a long-lasting β-adrenoceptor (β-AR) agonist and was once medicated as a bronchial dilatator, and is also used by body-building enthusiasts and athletes and in livestock breeding because of its anabolic effect on skeletal muscles and ability to promote lipolysis. Though prohibited from pharmacological uses, clenbuterol intoxication cases are frequently reported, and most of the cardiac symptoms are tachyarrhythmia. Here, we reported a different cardiovascular toxic response to clenbuterol. Using a rabbit model, we tested the dose-response pattern of the cardiovascular system to intravenous administration of clenbuterol...

Among patient with ACTH-dependent Cushing's syndrome, about 10-20% of those with ectopic ACTH syndromes (EAS) have occult or unknown tumors. Despite the intensive search for the culprit tumors by dynamic endocrine tests and imaging tests, it is often difficult to localize and confirm the source of occult ectopic ACTH secretion. We report a patient with EAS caused by a small bronchial carcinoid tumor, which was successfully localized by a selective pulmonary arterial sampling for the first time. A 69-year-old woman presented with typical Cushingoid features and elevated plasma ACTH and cortisol levels, which showed lack of circadian rhythm, no suppression by high-dose dexamethasone, and no response to CRH stimulation...

BACKGROUND: Bronchial artery (BA) embolization (BAE) is recommended as a minimally invasive therapy for hemoptysis, though some patients recover after only conservative treatment. OBJECTIVES: The purpose of our study was to assess the characteristics of BAs using multidetector row computed tomography (MDCT) and identify BAs requiring BAE without BA angiography (BAG). METHODS: We retrospectively studied 41 patients and classified the visualized BAs into groups based on their BAE and bleeding statuses...

The purpose of this study was to determine non-invasively the frequency of ectopic bronchial arteries (BA) (i.e., bronchial arteries originating at a level of the descending aorta other than T5-T6 or from any aortic collateral vessel) on multidetector-row CT angiograms (CTA) obtained in patients with hemoptysis. Over a 5-year period (2000-2005), 251 consecutive patients with hemoptysis underwent multidetector-row CT angiography of the thorax. From this population, 37 patients were excluded because of a suboptimal CTA examination (n = 19), the presence of extensive mediastinal disease (n = 15) or severe chest deformation (n = 3) precluding any precise analysis of the bronchial arteries at CTA...

OBJECTIVE: In this pictorial essay, we show the usefulness of MDCT angiography for visualization of the bronchial and nonbronchial systemic feeder vessels responsible for hemoptysis. CONCLUSION: By providing thin-section transaxial, multiplanar reconstruction, and 3D images, CT angiography using MDCT allows comparable or better images than conventional angiography with respect to the depiction of bronchial or nonbronchial systemic arteries. CT angiography is particularly useful for visualizing the ectopic origin of bronchial arteries and nonbronchial systemic collateral arteries...

Differentially Expressed Nucleolar TGF-beta1 Target (DENTT) is a new member of the TSPY/TSPY-like/SET/NAP-1 (TTSN) superfamily whose mRNA is induced by TGF-beta1 in TGF-beta1-responsive human lung cancer cells. Monkey DENTT mRNA contains a 2085-bp open reading frame that encodes a predicted polypeptide of 695 amino acids with five nuclear localization signals, two coiled-coil regions, and a domain that shows significant identity to a region that defines the TTSN superfamily. RT-PCR amplification and Western blot analyses showed DENTT mRNA and protein in adult monkey tissues, including the adrenal gland, cerebral cortex, and ovary...
