P Gailloud, L Gregg, M S Pearl, D San Millan
Thoracic vertebral arteries are anastomotic chains similar to cervical vertebral arteries but found at the thoracic level. Descending thoracic vertebral arteries originate from the pretransverse segment of the cervical vertebral artery and curve caudally to pass into the last transverse foramen or the first costotransverse space. Ascending thoracic vertebral arteries originate from the aorta, pass through at least 1 costotransverse space, and continue cranially as the cervical vertebral artery. This report describes the angiographic anatomy and clinical significance of 9 cases of descending and 2 cases of ascending thoracic vertebral arteries...

BACKGROUND: Doppler images of pulmonary vessels in pulmonary diseases associated with subpleural consolidations have been described. Color Doppler easily identifies such vessels within consolidations while spectral Doppler analysis allows the differentiation between pulmonary and bronchial arteries. Thus, Doppler helps in diagnosing the nature of consolidations. To our knowledge, Doppler analysis of pulmonary vessels within anesthesia-induced atelectasis has never been described before...

Non-typeable Haemophilus influenzae (NTHi) is a common opportunistic bacterial pathogen that primarily infects the respiratory mucosa. This study was conducted to assess clinical and microbiological data related to disease severity in patients with lower respiratory tract infections caused by NTHi in a tertiary care hospital in Mexico. NTHi isolates were subjected to serotyping, antimicrobial susceptibility evaluation, and analyses of β-lactamase production, genetic relatedness, and biofilm formation. Clinical and demographic data were retrieved from patients' records...

Surgical treatment for central bronchogenic carcinoma with invasion of the main bronchus and pulmonary artery often include bronchial anastomosis and pulmonary angioplasty. As a technique, video-assisted thoracoscopic surgery (VATS) lobectomy has proven to reduce the rate of occurrence of complications, and thereby obtain improved survival rates. In the present case study, its use in treating central bronchogenic carcinoma with invasion of the main bronchus and pulmonary artery is reported. A case study of a 68-year-old man with a history of smoking 15-20 cigarettes per day for 40 years is described, who presented with a cough and hemoptysis...

Semi-invasive or invasive aspergillosis occurring following chemotherapy with sunitinib is a rare condition with unknown incidence and prognosis. Here, we report a case involving a 59-year-old male who had a history of underlying stable aspergilloma and was newly diagnosed with metastatic renal cell carcinoma. Following surgical resection for renal cell carcinoma and adjuvant chemotherapy with sunitinib for 8 months, the patient presented with hemoptysis. Chest computed tomography revealed an increased soft tissue mass and air crescent sign of the underlying aspergilloma, combined with consolidation and bronchial artery hypertrophy around the lesion...

The purpose of this study was to clarify the recognizable computed tomography (CT) features of small cell lung carcinoma (SCLC).Contrast enhanced CT scans were reviewed retrospectively for mass location, mediastinal extension, and other concomitant findings in 142 patients with pathologically proven SCLC. SCLC was classified into hilar mass only (type I), hilar mass with ipsilateral mediastinal extension (type II), hilar mass with bilateral mediastinal extension (type III), and peripheral mass (type IV). When mediastinal lymphadenopathy (m-LAP) was indistinguishable from a hilar mass, we defined it as a mediastinal conglomerate mass (m-CM)...

BACKGROUND: Bronchiectasis is frequent in smokers with COPD, however there is only limited data on objective assessments of this process. OBJECTIVE: To objectively assess bronchovascular morphology, calculate the ratio of the diameters of bronchial lumen and adjacent artery (BA ratio), and identify those measurements able to discriminate bronchiectasis. METHODS: We collected quantitative computed tomography (QCT) measures of BA ratios, peak wall attenuation, wall thickness (WT), wall area, and wall area percent (WA%) at matched 4(th)-6(th) airway generations in 21 ever smokers with bronchiectasis (cases) and 21 never-smoking controls (control airways)...

PURPOSE: To reveal the patterns of the mediastinal course of the bronchial arteries (BAs). METHODS: The BAs were dissected to determine the positional relationships of their mediastinal courses with the tracheobronchus and the esophagus in 72 adult cadavers. RESULTS: The mediastinal courses of the 227 BAs found in this study were classified into 4 types. There were 61 and 163 BAs passing the right side (Type I) and the left side (Type II reaching dorsal surface (n = 98), or Type III reaching ventral surface (n = 65) of the tracheobronchus) of the esophagus, respectively...

A 28-year-old woman presented with 3-month history of fever of unknown origin and progressively increasing cough. She was diagnosed with pulmonary tuberculosis on bronchial lavage cultures. A chest X-ray performed on follow-up showed a new opacity in the left apical area of the chest. Computed tomography scan of chest showed a large 10 cm pseudoaneurysm of the left subclavian artery 1 cm from its take off from the arch of the aorta. The pseudoaneurysm was approached through a left posterolateral thoracotomy and opened following a proximal and distal control...

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...

OBJECTIVE: Despite technical advances of fenestrated and branched endografts, endovascular exclusion of aneurysms involving renal, visceral, and/or supra-aortic branches remains a challenge. In situ fenestration (ISF) of standard endografts represents another endovascular means to maintain perfusion to such branches. This study aimed to review current indications, technical descriptions, and results of ISF. METHOD: A review of the English language literature was performed in Medline databases, Cochrane Database, Web of Science, and Scopus using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines...

We present two interesting cases of isolated left subclavian artery from the pulmonary artery with symptoms of upper airway obstruction. The first patient had tetralogy of Fallot, pulmonary artery sling, bilateral superior caval veins, and left bronchial isomerism, suggesting heterotaxy syndrome. The second patient had a right aortic arch, isolated left subclavian artery, and bilateral arterial ducts. These two cases are interesting because of their rarity and uncommon presentation.

Occurrence of bronchial artery aneurysm is rare, and it has been detected in less than 1 % of all selective bronchial arteriography cases. Here, we present a case of a bronchial artery aneurysm caused by a tracheal stent migration. A 59-year-old man was operated on for esophageal cancer, where an esophageal-tracheal fistula occurred 1 week after operation. Surgical repair of the esophageal-tracheal fistula was performed using a muscle flap, but this not results in fistula closure. Consequently, a self-expanding covered metallic tracheal stent was implanted for rescue, and this resulted in fistula closure...

RATIONALE: Hypoxic pulmonary vasoconstriction (HPV) is the response of the pulmonary vasculature to low levels of alveolar oxygen. HPV improves systemic arterial oxygenation by matching pulmonary perfusion to ventilation during alveolar hypoxia, and is impaired in lung diseases such as the acute respiratory distress syndrome (ARDS) and in experimental models of endotoxemia. Epoxyeicosatrienoic acids (EETs) are pulmonary vasoconstrictors, which are metabolized to less vasoactive dihydroxyeicosatrienoic acids (DHETs) by soluble epoxide hydrolase (sEH)...

OBJECTIVES: Haemoptysis occurring in a Behçet's syndrome (BS) patient with pulmonary artery involvement (PAI) during follow-up is usually regarded as PAI relapse. However, bronchial artery enlargement (BAE) may be the source of haemoptysis in some patients. METHODS: A chart review at the end of December 2014 revealed 118 patients with PAI in our centre since 1979. Nine (all men) had recurrent haemoptysis during follow-up which could not be explained with relapse of PAI...

Objective: To observe if arterial traffic ambient PM2.5 (TAPM2.5) and wood smoke PM2.5(WSPM2.5) exposure can induce epithelial-mesenchymal transition (EMT) in human bronchial cells (HBEC). Methods: PM2.5 was collected from an arterial traffic road and a typical southern kitchen, and then the collections were extracted by DMSO. The viability of HBEC was measured by Cell Counting Kit (CCK-8) after culture with PM2.5-DMSO extracts for 24 hours. The expressions of EMT markers, including E-cadherin, cytokeratin, α-smooth muscle actin (α-SMA), vimentin and collagen typeⅠ (COL-Ⅰ) in HBEC were assayed by cell immunofluorescence and Western blot analysis after exposed to two different sources of PM2...

Angiographic findings in tuberculosis patients presenting with hemoptysis include hypervascularity, hypertrophy of systemic arteries, aneurysm, systemic to pulmonary anastomosis, and rarely, contrast extravasation. Bronchial arteries are the source of hemorrhage in majority of cases with non-bronchial systemic or pulmonary arteries being less common as the source. Rasmussen's Aneurysm is a very rare sequalae of Pulmonary Tuberculosis. We present one such case of Rasmussen's aneurysm and review of the relevant literature...

Purpose: The aim of the study was to evaluate safety, effectiveness, recurrence rate and 10-year survival after bronchial artery embolization (BAE) in benign and malignant etiologies. Methods: The retrospective study includes 100 BAE procedures in 88 patients. Underlying disease was classified as benign (n = 67) and malignant (n = 21) etiologies. Immediate bleeding control and procedure safety were evaluated in all patients. In 51 (58 %) patients, follow-up data with a median follow-up time of 1015 days (range, 494 to 3727 days) were acquired to assess overall survival, time-to-recurrence of bleeding and recurrence-free survival, using Kaplan-Maier estimates to compare differences between both subgroups...
