ABSTRACT
Objective:To investigate the diagnostic value of bronchial arteriography CT (BA-ACT) combined with bronchoscopy (BS) in bronchial Dieulafoy′s disease (BDD), and the role of bronchial artery embolization (BAE) in the treatment of BDD.Methods:Retrospective analysis was made on the clinical data of 5 patients suspected of being BDD treated by BS in Guangzhou First People′s Hospital or Guangzhou Thoracic Hospital from January 2008 to January 2018 due to hemoptysis. Bronchial arteriography (BAG) and BA-ACT were performed during the operation of interventional embolization. BAG rotary acquisition data were post-processed according to BS findings, and BA-ACT reconstruction images of the diseased bronchi and bronchial arteries were obtained. BS reexamination and clinical follow-up observation were carried out after embolization to analyze the effect of embolization.Results:There were one BDD lesion for the five patients respectively, and the BAG lacked characteristic manifestations. Bronchoscopy revealed BDD foci to present as papillary (case 1-case 3), nodular (case 4), or lirellate (case 5) subbronchial submucosal protrusion lesions. On the BA-ACT reconstruction plot, the BDD lesions of papillary, nodular and carination manifested correspondingly as a bronchial artery branches locally " pointed arch" shaped (cases 1-case 4) or " bead-like" (case 5) fold and protruding toward the bronchial lumen. The BDD lesions of the cases 1-case 4 retraction and disappearance after one BAE were observed by BS examination, and no hemoptysis recurrence during the follow-up period (54-91 months). The ridge like BDD lesion of the case 5 remained unchanged after BAE, and hemoptysis recurred at 71 months after the first BAE; the uncollapsed foci were supplied by two collateral vessels that confirmed by second BAG and BA-ACT, and no hemoptysis for 71 months followed up after second BAE.Conclusions:BA-ACT combined with BS enables a locative and qualitative diagnosis of BDD, and BAE is a very effective treatment method for BDD.
ABSTRACT
ABSTRACT Objective: Massive hemoptysis is one of the most serious complications in patients with cystic fibrosis (CF). This study aimed to evaluate the hemoptysis-free period following bronchial and non-bronchial artery embolization (BAE/non-BAE) in CF patients and to investigate predictors of recurrent bleeding and mortality by any cause. Methods: This was a retrospective cohort study of CF patients ≥ 16 years of age undergoing BAE/non-BAE for hemoptysis between 2000 and 2017. Results: We analyzed 39 hemoptysis episodes treated with BAE/non-BAE in 17 CF patients. Hemoptysis recurrence rate was 56.4%. Of the sample as a whole, 3 (17.6%) were hemoptysis-free during the study period, 2 (11.8%) underwent lung transplantation, and 3 (17.6%) died. The median hemoptysis-free period was 17 months. The median hemoptysis-free period was longer in patients with chronic infection with Pseudomonas aeruginosa (31 months; 95% CI: 0.00-68.5) than in those without that type of infection (4 months; 95% CI: 1.8-6.2; p = 0.017). However, this association was considered weak, and its clinical significance was uncertain due to the small number of patients without that infection. Conclusions: BAE appears to be effective in the treatment of hemoptysis in patients with CF.
RESUMO Objetivo: A hemoptise maciça é uma das complicações mais graves em pacientes com fibrose cística (FC). O objetivo deste estudo foi avaliar o período livre de hemoptise após a embolização arterial brônquica/não brônquica (EAB/não EAB) em pacientes com FC e investigar preditores de sangramento recorrente e mortalidade por qualquer causa. Métodos: Trata-se de um estudo retrospectivo de coorte de pacientes com FC com idade ≥ 16 anos submetidos a EAB/não EAB para o tratamento de hemoptise entre 2000 e 2017. Resultados: Foram analisados 39 episódios de hemoptise tratada por meio de EAB/não EAB em 17 pacientes com FC. A taxa de recidiva da hemoptise foi de 56,4%. Do total de pacientes, 3 (17,6%) permaneceram sem hemoptise durante o estudo, 2 (11,8%) foram submetidos a transplante de pulmão e 3 (17,6%) morreram. A mediana do período sem hemoptise foi de 17 meses. A mediana do período sem hemoptise foi maior em pacientes com infecção crônica por Pseudomonas aeruginosa (31 meses; IC95%: 0,00-68,5) do que naqueles sem esse tipo de infecção (4 meses; IC95%: 1,8-6,2; p = 0,017). No entanto, essa associação foi considerada fraca, e sua importância clínica foi considerada incerta em virtude do pequeno número de pacientes sem essa infecção. Conclusões: A EAB parece ser eficaz no tratamento de hemoptise em pacientes com FC.

Objective: To explore the preventive effect of bronchial artery embolization (BAE) for bleeding during bronchoscopy thermal ablation (BTA) in patients with central lung cancer. Methods: Clinical data of 49 patients with central lung cancer with airway stenosis treated by BTA were retrospectively analyzed. The patients were divided into two groups according to the method of treatment, in Group A (n=25) received only BTA, while in group B (n=24) received BAE before BTA. Then intraoperative bleeding of BTA was compared between 2 groups. Results: Among 25 patients in group A, 16 underwent successful BTA, 9 with mild bleeding in cases, 7 with moderate bleeding, whereas BTA had to be terminated due to massive bleeding in 9 cases. All 24 patients in group B underwent successful BAE, among them 22 underwent completed BTA, 18 with mild and 4 with moderate bleeding, and BTA was terminated in 2 cases due to massive bleeding. The intraoperative bleeding in group B was less than that in group A (P=0.02). Conclusion: BAE before BTA in patients with central lung cancer is safe and feasible, which can significantly reduce the risk of massive bleeding during BTA.
ABSTRACT
Objective To investigate the clinical effect of selective bronchial artery infusion chemotherapy for central squamous cell carcinoma of the lung.Methods 93 cases of central lung squamous cell carcinoma patients who were treated in our hospital from February 2015 to February 2017 were enrolled in the study.They were divided into the observation group (n =45) and the control group (n =48) according to the patients'final treatment.The observation group was treated with bronchial artery perfusion chemotherapy,and the control group was treated with systemic venous chemotherapy.The short-term effect and the improvement of lung function in the two groups were observed,and the prognosis of the patients was followed up.Results The short-term effect of the observation group was better than that of the control group (P ＜0.05),and the total effective rate of the observation group was 95.56％;The forced vital capacity (FVC)and forced expiratory volume in the first second (FEV,) of the observation group were (75.39 ± 6.88)％and (78.19 ± 7.79)％,respectively,which were significantly higher than those in the control group (P ＜0.05).The reoperation ratio of the observation group was 44.44％ after chemotherapy,which was significantly higher than that of the control group,with statistically significant difference (P ＜ 0.05).The median total survival time of the observation group was 17 months,which was significantly higher than that of the control group,with statistically significant difference (P ＜ 0.05).The incidence of adverse reaction in the observation group was 6.67％,which was significantly lower than that in the control group,with statistically significant difference (P ＜ 0.05).Conclusions Selective bronchial artery infusion chemotherapy for central lung cancer is effective and worthy of clinical application.
ABSTRACT
Objective To evaluate the efficacy difference of different embolization agents in transcatheter embolization for treating massive hemoptysis caused by systemic pulmonary circulation shunt(SPS). Methods The clinical and imaging data in 98 patients with hemoptysis complicating SPS,including bronchodilator in 72 cases,pulmonary tuberculosis in 18 cases and lung carcinoma in 8 cases. All cases were treated with bronchial arterial embolization (BAE). According to different used embolization agents, the cases were divided into the gelfoam group and polyvinyl alcohol(PVA)grains embolization group. All cases were followed up at postoperative 1 d,1,3,6 months as well as 1,2 years. The data were analyzed by using Ridit test. Results Ninety-eight cases of massive hemoptysis were confirmed by DSA,among them,84 cases were complicating pulmonary artery fistula, 18 cases were pulmonary venous fistula and 2 cases were mixed fistula; 32 cases were simple BPS, 62 cases were pulmonary circulation fistula existed in the bronchial arteries and non-bronchial artery and 4 cases were simple non-BPS. The two groups had no complications such as embolism,paraplegia,esophagus-trachea fistula and skin ischemic necrosis. The follow up on postoperative 1 d, at postoperative 1, 3,6 months and at postoperative 1,2 years indicated that among 48 cases in the gelfoam group, 20 cases were cured, 18 cases were significantly effective,6 cases were effective and 4 cases were ineffective,the effective rate was 91.7 % ;among 50 cases in the PVA grain embolization group, 38 cases were cured, 8 cases were significantly effective,4 cases were effective and O case was ineffective, the effective rate was 100%. Moreove no severe complications such as ectopic embolism, paraplegia, esophagus-trachea fistula and skin ischemic necrosis occurred. The difference between the two groups had statistical significance by Ridit analysis. Conclusion Transcatheter embolization for treating massive hemoptysis caused by SPS is safe and reliable,has small trauma, using PVA grains embolization can reduce the long term recurrence rate of hemoptysis.
ABSTRACT
A 71-year-old male with known bronchiectasis and atrial fibrillation was admitted to Seoul St. Mary's Hospital with recurrent transient ischemic attack. Radiofrequency ablation was performed to resolve the patient's atrial fibrillation, but failed. However, a fistula between the left circumflex artery and the bilateral bronchial arteries was found on computed tomography. Fistula ligation and a left-side maze operation were planned due to his recurrent symptom of dizziness, and these procedures were successfully performed. After the operation, the fistula was completely divided and no recurrence of atrial fibrillation took place. A coronary-bronchial artery fistula is a rare anomaly, and can be safely treated by surgical repair.

ABSTRACT
Hematemesis is a rare manifestation of a ruptured bronchial artery aneurysm (BAA) in the mediastinum. It is difficult to diagnose a ruptured BAA presenting as hematemesis, because it can be confused with other diseases, such as Boerhaave's syndrome, variceal disease, or a perforated ulcer. In this report, we describe a case of BAA resulting in hematemesis and mediastinal hemorrhage.

Objective To investigate imaging features and clinical characteristics of the small coronary-bronchial artery fistula (CBF). Methods By retrospective analysis of image data from May 2007 to November 2011 for coronary angiography in 30 284 patients without chronic lung or pulmonary vascular disease patients, 13 cases of small CBF (diameter of the end of fistula near coronary artery< 2 mm) were detected. Incidence of CBF was counted, its morphology was described, and its clinical features were preliminarily analyzed and summarized. Independent sample t test and χ2 test were used to compare diameters and incidences of CBF originatng from left and right coronary arteries. Results In this study primary CBF detection rate was 0.043%(13/30 284). The ends of CBFs near coronary arteries were slender and their diameter average was (1.57 ± 0.75) mm. In this study all of the CBF were from the right coronary artery and left circumflex coronary artery, finding no cases starting from the left anterior descending coronary artery. There was no significant difference between incidence of CBFs originating from the right coronary artery and left circumflex coronary artery coronary and the diameters of CBFs. In 13 cases of CBF, 9 cases of myocardial ischemic symptoms were caused by coronary artery stenosis, which was proven by angiography;Four cases without myocardial ischemic symptoms or with very atypical symptoms were finally diagnosed as cardiac neurosis. After branching, the CBF diameters of these coronary arteries were seen no evindently reduced, which suggested that the coronary bypass had less blood flow, and therefore had no significant hemodynamic significance. Conclusions Congenital CBF can exist in populations without chronic lung or pulmonary vascular disease. The main image features are that their diametes were small and all originate from the right coronary artery and left circumflex coronary artery. The most fundamental clinical features are that there're no symptoms of myocardial ischemia due to coronary artery steal and no obviously hemodynamic significance. It is important to well recognize this type of CBF for enriching radiographic knowledge, identifying various anatomic variations, and carrying out clinical diagnosis and treatment.
ABSTRACT
Objective To explore main technical points and clinical efficacy of individualized stepwise multiple embolization treatment for refractory hemoptysis. Methods To retrospectively analyze materials of 103 patients treated by individualized stepwise multiple embolization. According to disease categories, individualized stepwise multiple embolization treatment with polyvinyl alcohol and loaded sodium alginate microspheres as basic embolization agent were performed, after the type, number, abnormal branches, pulmonary circulation and systematic pulmonary shunt of targeted vessels were confirmed through radiography. To judge short(less than 3 months), medium(3 to 6 months) and long term(more than 6 months) efficacy, resolution of hemoptysis after operation were assessed. To evaluate efficacy of individualized stepwise multiple embolization treatment for refractory hemoptysis, Kaplan-Meier survival curves were used. According to the features of target vessels to supply blood, patients were classified into with SPS and without SPS. By using Log-Rank test, the effective rates of one-year were compared between them. Results Out of 103 patients, 215 target vessels were demonstrated, among which individualized stepwise multiple embolization was for 196 target vessels, peripheral embolization for 8 vessels, and main trunk embolization in 11 patients. The visits after operation were made to 103 patients after 6 to 50 months, with the medium of 21 months. Hemoptysis was instantly resolved in 97.1%(100/103). The effective rates were 94.5%,93.2%, 89.7%,88.9%,85.2%and 76.6%for one, three, six months and one, two and three years after operation. In 103 patients, patients with SPS were 22 and without SPS were 81. One-year effective rates with and without SPS were (69.50 ± 0.11)% and (98.30 ± 0.03)% , respectively (χ2=11.662,P<0.01). Conclusion Individualized stepwise multiple embolization treatment shows excellent short-term and mid-long term efficacy in the treatment of refractory hemoptysis.
ABSTRACT
Systemic arterial supply from the descending thoracic aorta to the basal segment of the left lower lobe without a pulmonary arterial supply is a rare congenital anomaly within the spectrum of sequestration lung disease. The most common pattern of anomalous systemic artery to the lung arises from the descending thoracic aorta and feeds the basal segments of the left lower lobe. We report an extremely rare case of a 29-year-old woman who underwent a successful left upper lobectomy for the treatment of recurrent massive hemoptysis from anomalous bronchial arterial supply to the lingular segment of left upper lobe.

BACKGROUND: Hemoptysis due to pulmonary tuberculosis (TB) frequently develops in Korea where the prevalence of TB is intermediate. The effect of bronchial artery embolization (BAE) on the control of massive hemoptysis has been well known. This study is designed to identify the risk factors contributing to rebleeding after BAE in patients with TB. METHODS: We retrospectively evaluated risk factors and the time for rebleeding after BAE in 72 patients presenting with hemoptysis. RESULTS: The overall immediate success rate of BAE was 93.1% (67 of 72 patients). Of the 29 patients (40.3%) who showed rebleeding after BAE, 13 patients experienced rebleeding within 1 month, and 14 patients between 1 month to 1 year. The existence of a shunt in angiographic finding, aspergilloma, and diabetes mellitus were risk factors of rebleeding after BAE in multivariate analysis. CONCLUSION: BAE was very effective for obtaining immediate bleeding control in hemoptysis associated with active TB or post-TB sequelae. It is important to observe whether or not rebleeding occurs up to 1 year of BAE especially in TB patients with aspergilloma, DM, or a shunt. Even rebleeding can be managed well by second BAE.

BACKGROUND: In uncontrolled hemoptysis patient, bronchial arteriography and bronchial artery embolization (BAE) is a important procedure in diagnosis and treatment. The aim of this study is to assess the incidence of contrast-induced nephropathy and the risk factors of contrast-induced nephropathy (CIN) after bronchial arteriography and BAE. METHODS: We retrospectively reviewed the medical records of the patients who underwent bronchial arteriography and BAE in two university hospitals from January 2003 to December 2011. CIN was defined as rise of serum creatinine more than 25% of baseline value or 0.5 mg/dL at between 48 hours and 96 hours after bronchial arteriography and BAE. We excluded patients who already had severe renal insufficiency (serum creatinine> or =4.0) or had been receiving dialysis. RESULTS: Of the total 100 screened patients, 88 patients met the enrollment criteria. CIN developed in 7 patients (8.0%). The mean duration between the exposure and development of CIN was 2.35+/-0.81 days. By using multivariate analysis, serum albumin level was found to be significantly associated with the development of CIN (p=0.0219). CONCLUSION: These findings suggest that the incidence of CIN was higher than expected and patients with hypoalbuminemia should be monitored more carefully to prevent the development of CIN after bronchial arteriography and BAE.

Objective To evaluate subclavicular angiography with brachial-axillary artery externally and temporally occluded in depicting hemoptysis-related ectopic arteries originating from shoulder, neck and chest wall in the interventional treatment of hemoptysis. Methods A retrospective analysis of the medical records and angiograms of 103 patients who underwent transarterial procedures for hemoptysis was carried out. The arteries originating from the subclavicular arteries supplying the shoulder, the neck and the chest wall, ectopic bronchial arteries (EBA) as well as non bronchial systemic arteries (NBSA), were depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. The number and distribution of the responsible aberrant arteries were investigated. Results Of the hemoptysis-related arteries(n=372) depicted and embolized in the studies, 51.9% was normally-originated bronchial arteries(n=193),6.7% was ectopic bronchial arteries (n=25),41.4% was NBSA(n=154).Both anomalous and NBSA arising from subclavicular-axillary area(n=80) were accounted for 21.5% (80/372) of all aberrant arteries, and 44.7%(80/179) of all anomalous and NBSA (n=25+154=179).Of those arising from subclavicular-axillary arteries,56.3%(45/80) were found to be originated from the internal thoracic artery (n=45),98.2%(112/114)of responsible internal thoracic arteries and their distal branches were well depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. Conclusion Subclavicular-axillary artery is a very important vessel where EBA and NBSA originate. Subclavicular angiography with brachial-axillary artery externally and temporally occluded could help to determine the abnormal arteries in the region quickly. The method should be taken as a routine procedure for interventional treatment of hemoptysis.
ABSTRACT
Objective To discuss the characteristics of multiple blood supplies and the significance of multiple intra-arterial embolization in massive hemoptysis. Methods Forty-four patients with massive hemoptysis underwent digital subtraction angiography (DSA) and intra-arterial embolization after ineffective medical treatment. The characteristics of blood supply of lesions,the methods of intra-arterial embolization and the clinic efficacy were retrospectively analyzed. Results All the patients, one artery was embolized in 9 patients,2 arteries were embolized in 18,3 in 14 and 4 in 3. The hemoptysis decreased or ceased immediately after intra-arterial embolization in 43 patients and recurrence within lweek in 2,which were controlled with additional emblization. 1 patient died in surgery. Conclusion The lesions of massive hemoptysis had complicated blood supplies,and multiple intra-arterial embolization was very important.
ABSTRACT
A bronchial artery aneurysm (BAA) is uncommon and usually associated with chronic inflammatory lung disease or a systemic vascular condition, which is rarely the etiology of mediastinal hemorrhage. A middle-aged person presented with spontaneous hemothorax and hemomediastinum. A diagnostic evaluation identified a bronchial artery aneurysm as the source. To prevent further rupture, we performed a bronchial artery embolization. In the absence of trauma or other causes for hemothorax and mediastinal hemorrhage, the possibility of a BAA should be considered. A bronchial artery aneurysm can be managed by interventional techniques as well as surgery.

Objective To explore the long-term effect of bronchial artery, embolization (BAE) in patients with massive hemoptysis and the factors associated with prognosis. Methods Ninety six patients underwent BAE from 2002 to 2008 for the management of mass hemoptysis were retrospectively analyzed. Of them, BAE was successfully performed in 94 patients (mean age 43 years, age range 21 to 80 years), including active or inactive tuberculosis (89 cases), bronchiectasis (2 cases) and pulmonary carcinoma (5 cases). Results BAE resulted in an immediate cessation of hemoptysis in 94 of the initial 96 patients (97.9%). The rate of hemoptysis controlling at 30 d, 90 d, 1 year and 2 year after the BAE was 93.6% (88/94), 86. 2% (81/94), 81.9% (77/94) and 78.7% (74/94) respectively. Haemoptysis recurred in 9 patients in 30 days after the BAE due to missing of target vessel or recanalization. Five patients had recurrence of haemoptysis after 30 days and 2 patients recurrent after 90 days due to development of systemic collateral, progress in primary lesions and secondary infection. Conclusion BAE is an effective technique in the emergency treatment of massive hemoptysis. Avoiding missing target vessel, selecting the appropriate embolic material, paying attention to treatment of the primary disease after BAE, and preventing infection would improve the effects of BAE for massive hemoptysis.
ABSTRACT
Objective To present one case of bronchial artery aneurysm successfully treated with endovascular interventional procedure and review literature. Methods A 67-year-old man was diagnosed with mediastinal bronchial artery aneurysm accompanied with tuberculous pleurisy by chest imaging. The aneurysm was treated via transcatheter bronchial artery embolization combined with endovascular stent-graft placement in the thoracic aorta under DSA guidance. Results Postprocedural angiography showed satisfactory exclusion of the aneurysm and no endolead. Conclusion Interventional therapeutic management of bronchial artery aneurysm is feasible and accurate.
ABSTRACT
BACKGROUND: Recently, many institutions have acquired multi-detector computed tomography (MDCT) systems. This made it easier and more convenient to use MDCT as a initial diagnostic modality for hemoptysis. The purpose of this study was to evaluate the usefulness of MDCT before bronchoscopy and/or bronchial arterial embolization (BAE) for hemoptysis. METHODS: We studied a total of 125 patients with hemoptysis who underwent, between 2006 and 2008, MDCT in a routine protocol before bronchoscopy and/or BAE. One hundred two patients underwent bronchoscopy and 29 patients underwent BAE. We compared the usefulness of MDCT and bronchoscopy for detecting the bleeding site and identifying the cause. We also evaluated our ability, using MDCT, to detect instances where the bronchial artery caused hemoptysis. RESULTS: The rate of detection of a bleeding site was 75.5% on MDCT and 50.9% on bronchoscopy. MDCT and bronchoscopy detected the bleeding site in agreement in 62.7% of patients. MDCT alone found the bleeding site in 27.5% of cases. MDCT identified the cause of hemoptysis in 77.5% and bronchoscopy in 11.8%. In 29 patients who underwent BAE, we detected a total of 37 hypertrophied bronchial arteries that were causing hemoptysis. Of 37 bronchial arteries, 23 (62.2%) were depicted on MDCT. CONCLUSION: MDCT is superior to bronchoscopy for detecting the bleeding site and identifying the cause of hemoptysis. MDCT can also predict the side of affected bronchial artery with depiction of hypertrophied bronchial artery and localizing the bleeding site. Doing MDCT before bronchoscopy and BAE can provide a guideline for the next step.
