Bronchial arteries AND ectopic

SUMMARY: Severe Cushing's syndrome from an ectopic adrenocorticotropic hormone-producing tumour is rare but often demands rapid diagnostics and treatment of hypercortisolism with its comorbidities. Pharmacotherapy of hypercortisolism by ketoconazole, metyrapone and osilodrostat is currently available. If unsuccessful or insufficient a bilateral adrenalectomy is an option. We present a 28-year-old female with severe Cushing's syndrome caused by a bronchial metastatic neuroendocrine tumour (NET)...

BACKGROUND: Drug-eluting beads bronchial arterial chemoembolization (DEB-BACE)/bronchial artery infusion chemotherapy (BAI) have been investigated as treatment options for advanced non-small cell lung cancer (NSCLC), especially for those patients who develop refractoriness to or are intolerant to systemic chemotherapy. This retrospective study aimed to compare the outcomes of DEB-BACE/BAI with and without programmed cell death protein 1 (PD-1) blockade for advanced NSCLC, and to investigate the effectiveness and safety of combination regimens...

Objective: To estimate the value of multidetector computed tomography angiography (MDCTA) and image analysis before bronchial artery embolization (BAE) in the treatment of hemoptysis. Methods: A total of 165 patients with hemoptysis who underwent BAE at the Department of Interventional Radiology of Xiangyang Central Hospital from August 2017 to June 2021 were retrospectively analyzed and divided into two groups: MDCTA group [with preoperative MDCTA, 88 patients,63 males and 25 females,aged 23 to 87(62.6±12...

PURPOSE: To evaluate the outcome of dual-vessel intervention (DVI), including bronchial or pulmonary arterial embolization (B/PAE), in managing massive hemoptysis caused by cavitary lung lesions (with or without aspergilloma) and identify cavitary angiographic features influencing DVI procedures. METHOD: A retrospective analysis of the medical records and angiograms of 15 patients who underwent DVI for massive hemoptysis was performed. RESULTS: The most frequent causes of cavitary lung lesions were tuberculosis (TB) (8/15, 53%) and bronchiectasis (6/15, 40%)...

BACKGROUND: Ectopic bronchial artery and non-bronchial systemic arteries may be the culprit vessels of hemoptysis. The main cause of clinical failure of bronchial artery embolization is incomplete embolization caused by the misidentification of the culprit arteries by conventional angiography. Multidetector computed tomography angiography is useful for visualizing the culprit arteries. CASE PRESENTATION: An 82-year-old man was admitted with hemoptysis. Preprocedural multidetector computed tomography angiography revealed an ectopic bronchial artery branching from the right thyrocervical trunk...

BACKGROUND: Massive hemoptysis due to aspergilloma is a rare but life-threatening complication. Bronchial artery embolization is recommended as a definitive treatment for massive hemoptysis. Polyvinyl alcohol is widely used in bronchial artery embolization. A very small number of studies have reported disrupted polyvinyl alcohol, which may cause ectopic embolism. CASE PRESENTATION: This case highlights an unusual phenomenon in which polyvinyl alcohol fragments appeared on pathological examination in a 61-year-old man, ethnic Han, with massive hemoptysis caused by aspergilloma for whom bronchial artery embolization failed...

To identify and evaluate the spectrum and prevalence of variations in bronchial artery (BA) origin by multidetector computed tomography (MDCT) and digital subtraction angiography (DSA) in a large population with hemoptysis.From July 2008 to June 2015, data from 600 individuals with hemoptysis who underwent MDCT and DSA were retrospectively analyzed. The pattern of BA origin was investigated and classified according to distribution.A total of 1674 BAs were evaluated, 866 were right BA and 808 were left BA. Most BAs originated from the upper descending thoracic aorta, classified as orthotopic origin (n = 1464, 87...

BACKGROUND: Multidetector computed tomography (MDCT) angiography is a useful examination to detect the source of the bleeding in patients with hemoptysis. The aim of the study was to prospectively evaluate the role and clinical efficacy of MDCT angiography before bronchial artery embolization (BAE) for the management of hemoptysis, and to investigate the predictors of early recurrence. METHODS: It is a double-center study which included 57 hemoptysis patients undergoing MDCT angiography prior to BAE from August 2019 to July 2020...

AIM: to compare the antianginal and pulse slowing effects, the impact on the ectopic myocardial activity as well as the safety of the treatment with beta - adrenoblocker bisoprolol, calcium antagonist verapamil and the combination of bisoprolol with amlodipine in patients with stable angina (SA) and bronchial asthma (BA). MATERIALS AND METHODS: The study included 90 patients with SA II-III functional class (FC) having concomitant persistent asthma of moderate severity, controlled, without exacerbation...

Rationale . Hemoptysis is a rare but often life-threatening condition in pediatric patients. Massive hemoptysis can easily lead to asphyxia, respiratory failure, shock, and even death. The most common causes of severe hemoptysis are lower respiratory tract infection, vascular malformation, and bronchial foreign body. We present an unusual case of massive hemoptysis caused by malformation of the bronchial artery, which includes bronchial artery hypertrophy, bronchial-pulmonary artery fistula, and ectopic bronchial artery...

Primary hyperparathyroidism (PHPT) is the most common cause of hypercalcemia in the clinical setting and affects 0.3% of the population. Parathyroidectomy is the only definitive cure. Unfortunately, even in the most experienced hands, persistent primary hyperparathyroidism (P-PHPT) occurs in 4.7% of the patients. Ectopic adenomas are difficult to localize before and during operation and usually end up with P-PHPT. Herein, we presented a case with P-PHPT due to mediastinal parathyroid adenoma that was successfully ablated with selective arterial embolization...

PURPOSE: To evaluate the influence of ectopic origin of bronchial arteries (BAs) on bronchial artery embolization (BAE) for hemoptysis. METHODS: CT and angiography images of 50 consecutive sessions in 39 patients (aged 26-93 years; mean, 70.6 years) who underwent BAE for hemoptysis from April 2010 to December 2019 were reviewed. We defined ectopic BA as a systemic artery originating from other than the T5-T6 vertebral level of the descending aorta with course along the major bronchi...

OBJECTIVE: To investigate the clinical effect of endovascular embolization (EVE) in the treatment of hemoptysis of systemic arterial origin in children. METHODS: A total of 20 children with hemoptysis of systemic arterial origin who underwent EVE from January 2016 to November 2017 were enrolled. The method for embolization was analyzed and the clinical outcome was evaluated. RESULTS: Offending vessels were bronchial artery (BA) in 14 children, non-bronchial systemic artery (NBSA) in 1 child, and BA and NBSA in 5 children...

OBJECTIVES: To compare the average number of culprit arteries per patient, clinical success rate, and hemoptysis-free survival rate between hemoptysis patients with multidetector computed tomography (MDCT) angiography prior to bronchial artery embolization (BAE) and those without preprocedural MDCT angiography METHODS: This retrospective study was approved by the institutional review board with waiver of patient informed consent. From September 2012 to March 2017, 157 consecutive hemoptysis patients had been undergoing BAE...

BACKGROUND: Cushing's syndrome due to ectopic ACTH secretion has been associated with many cancers; most commonly small cell carcinoma of the lung and bronchial carcinoid tumors. Usually, patients who confer this diagnosis have poor prognosis. CASE PRESENTATION: A 66-year-old female presented with worsening shortness of breath and weakness over three days. Initial laboratory derangements included severe hypokalemia and metabolic alkalosis. Treatment included high amounts of potassium chloride and acetazolamide...

BACKGROUND: We have routinely performed three-dimensional computed tomography (3-D CT) prior to video-assisted transmediastinal esophagectomy to evaluate the small arteries in the mediastinal operative field. This evaluation would be helpful in performing mediastinoscopic esophagectomy. METHODS: Thirty-one patients who underwent transmediastinal esophagectomy with preoperative evaluations by 3-D CT were the study subject. The bronchial arteries depicted by the 3-D CT were classified by their origin and laterality...

PURPOSE: To retrospectively assess the value of computed tomographic (CT) bronchial arteriography (BA) with 320-row multidetector CT in the management of patients with recurrent hemoptysis immediately after bronchial artery embolization (BAE). MATERIALS AND METHODS: Among 135 consecutive patients treated with BAE between April 2014 and March 2016, recurrent hemoptysis developed in 15, and 10 subsequently underwent multidetector CT. Vascular abnormalities and associated anatomy were evaluated to determine the potential cause of BAE failure, and the clinical impacts of CT BA were analyzed...

Bronchial arteries commonly originate from thoracic aorta between T5 and T6. Ectopic origins from aortic arch, supraortic trunks and their branches, coronary arteries, and even abdominal aorta have been described in the literature. In some circumstances, such as pulmonary artery malformations, chronic embolism, or inflammatory diseases of the lung, the bronchial arteries become hypertrophied and eventually could be the only supply of pulmonary circulation. Here, we describe a case of an elderly man who presented an unusual pattern of bronchial arteries of the right lung combined with severe bilateral hypertrophy of bronchial vessels...
