Bronchial arteries

A K Singh, Varun Gupta, Bindu Rani, Manish Kumar, Saurabh Kaushik
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...

OBJECTIVES: Surgery for vascular anomalies can occasionally fail to relieve symptoms, especially when severe tracheobronchial malacia persists. We studied outcomes in children who underwent airway stenting for severe post-surgical airway malacia and tested known clinical and surgical prognostic factors. METHODS: Among 257 children evaluated for tracheobronchial vascular compression, we reviewed the clinical charts for the 59 patients (23%) who underwent surgery...

Inhaled nitric oxide (iNO) is commonly used in the treatment of very ill pre-term newborns. Previous studies showed that exogenous NO could affect endothelial NO synthase (eNOS) activity and expression in vascular endothelial cell cultures or adult rat models, but this has never been fully described in newborn rat lungs. We therefore aimed to assess the effects of iNO on eNOS expression and activity in newborn rats. Rat pups, post-natal day (P) 0 to P7, and their dams were placed in a chamber containing NO at 5 ppm (iNO-5 ppm group) or 20 ppm (iNO-20 ppm group), or in room air (control group)...

Cystic fibrosis (CF) patients are at risk for life-threatening hemoptysis, sometimes necessitating bronchial arterial embolization (BAE). Spinal artery embolization and pulmonary infarction are commonly cited procedural risks, yet respiratory failure and death are underappreciated. We conducted a retrospective institutional review of our outcomes after BAE for hemoptysis in CF and present three cases highlighting this complication. From 2007 to 2015, 12 patients underwent 17 BAE procedures for hemoptysis at our institution...

PURPOSE: Thoracoscopic lobectomy for congenital cystic lung disease has become an accepted and in many institutions the preferred technique. However, the technical challenges are many. Previous endoscopic staplers (12 mm) used commonly in adults are too large for use in infants This study evaluates the safety and efficacy of using a 5 mm stapling device to seal and divide major pulmonary structures. METHODS: From July 2014 to March 2016, 26 patients of age 6 weeks to 13 months underwent thoracoscopic lobectomy for CPAM or sequestration...

PURPOSE: To evaluate the use of the 64-slice spiral computed tomography (CT) with perfusion-weighted imaging in the early diagnosis of ground-glass opacity lung cancers. METHODS: 412 patients with ground-glass opacities found by conventional CT scan in our hospital, and deemed highly suspected of being lung cancers, were enrolled in the study between February of 2012 and February of 2015. Sixty four-slice spiral CTs with perfusion-weighted imaging were carried out on all patients, and the latest nodular contrast analysis software, MPR2D, 3D reconstruction technology, MIP technology and perfusion scanning technology were used to analyze lesion types, density, blood supply, peripheral signals, doubling time and tissue perfusion characteristics...

OBJECTIVES: Bronchial lumen to pulmonary artery diameter (BA) ratio has been utilized to investigate pulmonary pathology on high-resolution CT images. Diseases affecting both the bronchi and pulmonary arteries render the BA ratio less useful. The purpose of the study was to establish bronchial lumen diameter to vertebral body diameter (BV) and pulmonary artery diameter to vertebral body diameter (AV) ratios in normal cats. METHODS: Using high-resolution CT images, 16 sets of measurements (sixth thoracic vertebral body [mid-body], each lobar bronchi and companion pulmonary artery diameter) were acquired from young adult female cats and 41 sets from pubertal female cats...

BACKGROUND: Although there have been several large reviews documenting the complications following intraoperative transesophageal echocardiography (TEE), most of these prior reports are almost 2 decades old and may not reflect current practices. The purpose of this study was to determine the incidence and types of complications following TEE in a contemporary cardiac surgical population. METHODS: We conducted a retrospective analysis of all cardiac surgical patients having undergone an intraoperative TEE between April 1, 2004, and April 30, 2012...

We report a male patient who underwent bronchoscopic instillation of glue to control moderate hemoptysis which later led to the development of postobstructive pneumonia and extensive foreign body reaction in the bronchial wall and the lung distal to the glue application. He continued to have intermittent hemoptysis and underwent bronchial artery embolization. However, recurrent moderate hemoptysis eventually led to pneumonectomy, which showed severe foreign body reaction in bronchi- and post-obstructive changes in the lung parenchyma and the draining lymph nodes...

BACKGROUND: Hemoptysis is common in pulmonary aspergilloma. Current treatment modalities such as surgical resection or bronchial artery embolization (BAE) are limited by lack of technical expertise and risk of recurrence, respectively. We describe our experience of treating aspergilloma and hemoptysis with bronchoscopic instillation of voriconazole. METHODS: We retrospectively reviewed records of patients with symptomatic aspergilloma undergoing bronchoscopic voriconazole instillation...

BACKGROUND: Single-port video-assisted thoracoscopic surgery (VATS) left upper lobectomy is difficult amongst all the lobes. At the beginning of single-port lobectomies, the upper lobes were believed not to be amenable for single-port approach due to the difficult angulation for staplers. Gonzalez reported the first single-port VATS left upper lobectomy in 2011. METHODS: We report a new technique of single-port VATS left upper lobectomy with the concept of "reverse direction"...

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...

Absent pulmonary valve syndrome (APVS) is a rare congenital heart disease with severe pulmonary insufficiency, characterized with aneurysmal dilation in the pulmonary artery and one or both of its branches. We presented a rare case with APVS and literature review in this letter. Prenatal USG examination of the fetus at the 26th week of gestation revealed severe polyhydramnios, dilatation at right ventricle, and abnormal appearance of the heart. At the 31st gestational week, the baby was born with cesarean section...

Chronic thromboembolic pulmonary hypertension (CTEPH) is a late sequel of venous thromboembolism that cannot be completely reproduced in animal models. The prevalence of CTEPH in humans is estimated at roughly 17-20 per million; however, partly because up to 50% of patients with CTEPH never experience symptomatic pulmonary embolism, precise numbers on the incidence and prevalence are not known. Because CTEPH is diagnosed at a median age of 63 years in patients who often have other concomitant cardiovascular disease or lung disease, assessment of pathophysiology in patients can be challenging, We do know that CTEPH is a dual vascular disorder...

Angiogenesis is vital for tumor growth but in well-vascularized organs such as the lung its importance is unclear. This situation is complicated by the fact that the lung has two separate circulations, the pulmonary and the systemic bronchial circulation. There are few relevant animal models of non-small cell lung cancer, which can be used to study the lung's complex circulations, and mice, lacking a systemic bronchial circulation cannot be used. We report here a novel orthotopic model of non-small cell lung cancer in rats, where we have studied the separate contributions of each of the two circulations for lung tumor growth...
