Massive paediatric pulmonary haemorrhage in Dieulafoy's disease: Roles of CT angiography, embolisation and bronchoscopy.

Acute, major pulmonary haemorrhage in children, is rare, may be life-threatening and at times presents atypically. Dieulafoy's disease of the bronchus presenting with recurrent or massive hemoptysis was first described in adults. Prior to reviewing the literature, we report an illustrative case of bronchial Dieulafoy's disease (BDD) in a child presenting unusually with massive apparent hematemesis. The source of bleeding is a bronchial artery that fails to taper as it terminates within the bronchial submucosa. A high index of suspicion is required to identify such lesions via radiological imaging and the role of bronchial artery embolisation is highlighted with video images of angiography included.

Bronchial Dieulafoy's disease: a retrospective analysis of 73 cases.

BACKGROUND: Bronchial Dieulafoy's disease (BDD) is a rare disease that is known to be a cause of hemorrhage. The characteristics of this disease are still unknown. The present study describes the disorder based on a review of the world's literature, emphasizing the diagnostic and therapeutic views. METHODS: A comprehensive research of BDD of the PubMed, Google Scholar, and Web of Science databases was performed. The following data were collected: patient characteristics; chest imaging, bronchoscopy, vascular angiography, and histopathologic examination findings; and treatment rendered. RESULTS: 73 cases of BDD have been reported from 1995 to 2019. Most of the cases occurred in Asia (52.1%), followed by Europe (31.5%). Chest imaging findings were non-specific. The main bronchoscopy finding was a nodular or protruding lesion (60.9%). 19 patients underwent bronchoscopic biopsies, 17 had bleeding, and 6 died. Four patients were successfully shown to have vascular malformations under mucosal protrusion by endobronchial ultrasound scan (EBUS). Vascular angiography mainly showed tortuous, dilated bronchial arteries. Vascular angiography mainly showed tortuous, dilated bronchial arteries. The arterial supply was mainly provided by bronchial arteries (48 cases) and the pulmonary circulation (4 cases). The lesions were mainly located in the right bronchus (53 cases). Selective bronchial artery embolization (BAE) was attempted in 38 patients and 20 patients underwent lobectomies. Emergency resection was performed in 15 patients, all of whom survived and had no recurrent hemoptysis. CONCLUSIONS: Massive hemoptysis was the common manifestation of BDD. Vascular angiography and EBUS is a very useful examination before biopsy. BAE may be used in stable patients, or patients who cannot tolerate surgery, while surgical resection should be considered in patients who are unstable, patients with uncontrolled hemoptysis, or following BAE failure.

[The computed tomography angiography features of Dieulafoy disease of the bronchus].

Objectives: To summarize the computed tomography angiography(CTA) features of Dieulafoy disease of the bronchus. Methods: The clinical, imaging and pathological data of Dieulafoy disease of the bronchus diagnosed in our hospital from July 4, 2010 to June 20, 2016 were retrospectively analyzed, and the CTA imaging features of the abnormal bronchial arteries were summarized. Results: There were 6 cases of bronchial Dieulafoy disease, 5 males and 1 female, with an average age of (55±15) years. Three cases had smoking history, and 2 cases had underlying diseases such as tuberculosis and acute myeloid leukemia. The common manifestations were hemoptysis, fever and pneumonia. Three patients got CTA examination, and bronchial arteries of Dieulafoy disease of the bronchus were circuitous and dilated, with the vascular diameter lager than 2 mm, no gradual narrowing but sudden truncation. Some circuitous vessels went into bronchial lumen as nodules. The bronchoscopy biopsy of 2 cases of bronchial nodules led to severe hemorrhage, with one death and one survival by successful management. Conclusions: Bronchial arteries of Dieulafoy disease of the bronchus were circuitous and dilated, and some circuitous vessels went into bronchial lumen as nodules, this demonstration can be used to diagnose Dieulafoy disease of the bronchus. For patients with hemoptysis, bronchial biopsy should only be performed after CTA examination if this disease is suspected.

Massive hemoptysis in pregnancy treated by ECMO combined with electronic bronchoscopy: A case report.

Background: Massive hemoptysis during pregnancy is very rare. Dieulafoy's disease is one of the causes of massive hemoptysis. There are few reports of ECMO use to treat massive hemoptysis during pregnancy. Findings: We report for the first time a patient with Dieulafoy's disease diagnosed at 29 weeks of pregnancy. The patient's hemoptysis occurred rapidly with large volumes. The bleeding amount reached 500 ml within half an hour, with the development of asphyxia and respiratory and cardiac arrest due to a blood clot blocking the airway. After successful cardiopulmonary resuscitation, the ventilator could not maintain effective ventilation. Emergency establishment of VV-ECMO was performed to maintain oxygen, and hemostasis was successfully achieved by performing bronchial artery embolization twice. We successfully cleaned blood clots in the airway four times by freezing and using a foreign body retrieval basket with an electronic bronchoscope. At the same time, small and smooth nodular lesions were found under bronchoscopy, and blood vessels with a diameter of 1.5 mm were found under Doppler mode with an ultrasonic bronchoscope, which was consistent with a diagnosis of Dieulafoy's disease. VV-ECMO was successfully stopped on the 3rd day of the disease course, tracheal intubation was successfully removed on the 5th day of the disease course, and the patient was discharged with no complications on the 16th day of the disease course.

Pathological features of vascular wall in Dieulafoy's disease.

AIMS: Although there are many clinical reports on Dieulafoy's disease, there are few studies on the pathological structure of vascular wall in Dieulafoy's disease. METHODS: In this study, the main structural changes of the intima and media of the vascular wall were observed by special staining and immunohistochemical methods in the subjects of Dieulafoy's disease of stomach and intestine. RESULTS: There were many vessels of different sizes in the submucosa, with uneven wall thickness of the vessels. Compared with the normal control group, the content of blue collagen fibers between the vascular smooth muscle cells in the lesion group was increased, the elastic fibers were thickened, and the internal elastic plate was arranged stiff or even interrupted. CONCLUSIONS: The increase of collagen and elastic fibers between the smooth muscle cells of the medium membrane and the destruction of the structure of the inner elastic plate may be the structural basis of vascular lesions leading to Dieulafoy's disease.

Dieulafoy's disease of the bronchus: rare but potentially fatal: a case report and a review of literature.

BACKGROUND: Dieulafoy's disease of the bronchus can cause massive and even fatal hemoptysis. Even though it is rare, it should be considered by physicians all over the world. This paper reports a case of bronchial Dieulafoy's disease and summarizes the data of similar cases reported in literature. METHODS: We report a case of bronchial Dieulafoy's disease (BDD) in Tunisia. We also present a review of literature related to BDD from 1995 to 2022 using the PubMed, Google Scholar, web of science and Chinese National Knowledge Infrastructure Databases. Clinical characteristics, chest imaging, bronchoscopic and angiographic findings were summarized. Treatment courses were identified as well as patients' outcome. RESULTS: We report the case of a 41-year-old man, so far in good health, presenting with massive hemoptysis. Bronchoscopy showed blood clots and a protruding lesion covered by mucosa with a white pointed cap at the entrance of the right upper lobe. Biopsies were not attempted. Embolization of bronchial artery was first realized and was not successful, with post procedure complications. Surgical intervention stopped the bleeding and pathological examination of the resected specimen confirmed Dieulafoy's disease of the bronchus. Ninety cases of BDD were reported from 1995 to 2022. The main symptom was hemoptysis. Chest imaging findings were not specific. The diagnosis of BDD was mainly based on the bronchoscopy, branchial angiography and pathological findings or surgical specimens. Bronchoscopy findings were mostly nodular or prominent lesions (52.4%). Twenty-eight patients underwent bronchoscopic biopsies, 20 had massive bleeding and 10 died. Bronchial angiography mainly showed tortuous and dilation of bronchial artery, and the lesions were mainly located in the right bronchus. Selective bronchial artery embolization (SBAE) was performed in 32 patients and 39 patients underwent surgery. CONCLUSION: To our knowledge, this is the first case of bronchial Dieulafoy's disease to be reported in Tunisia and North Africa. When the diagnosis is suspected, bronchoscopic biopsy should be avoided as it might lead to fatal hemorrhage. Selective bronchial artery embolization can stop the bleeding, but surgery can be required.

Efficacy of Bronchial Artery Embolization for Clinically Suspected Bronchial Dieulafoy's Disease.

BACKGROUND: The efficacy of bronchial artery embolization (BAE) for bronchial Dieulafoy's disease (BDD) has not been well established. OBJECTIVE: This study aimed to evaluate the safety and efficacy of BAE in patients with clinically suspected BDD presenting with major hemoptysis, and to describe angiographic findings. METHODS: 17 patients (all men; mean age, 53.5 years) diagnosed with clinically suspected BDD by bronchoscopy (n = 7) or CT angiography (CTA) (n = 10) and who underwent BAE after directional and segmental localization of the target bronchus were enrolled. BAE was performed at the culprit bronchial artery traveling toward the target bronchus, regardless of the pathologic angiographic findings. Angiographic findings and clinical outcomes of BAE, including technical and clinical success, complication, recurrent hemoptysis, and follow-up imaging, were retrospectively reviewed. RESULTS: Representative angiographic findings included parenchymal hypervascularity prominent in the lobe where the BDD was located (82.4%), bronchial artery hypertrophy (70.6%), and contrast extravasation into the bleeding bronchus (17.6%). BAE was technically successful in all patients. All hemoptysis ceased within 24 h. No procedure-related complications occurred. During a mean follow-up of 491.9 days, 1 (6%) patient experienced recurrent hemoptysis. Follow-up bronchoscopy or CT performed in 10 (58.8%) patients showed the disappearance of pre-existing lesions (n = 9) or glue cast within the target bronchial artery (n = 1). CONCLUSION: Bronchial angiography showed pathologic findings in most patients with clinically suspected BDD. BAE assisted by bronchoscopy or CTA localization is a safe and effective treatment for patients with clinically suspected BDD with excellent short- to mid-term results.

Recurrent hemoptysis in pediatric bronchial Dieulafoy's disease with inferior phrenic artery supply: A case report.

BACKGROUND: Bronchial Dieulafoy's disease (BDD) is characterized by the erosion of an anomalous artery in the submucosa of the bronchus. The etiology of pediatric BDD is mainly congenital dysplasia of bronchus and pulmonary arteries, which is different from chronic inflammatory injury of the airway in adult patients. The internal thoracic artery, subclavian artery, and intercostal artery are known to be involved in the blood supply to the BDD lesion in children. CASE SUMMARY: We report a case of BDD in a 4-year-old boy with recurrent hemoptysis for one year. Selective angiography showed a dilated right bronchial artery, and anastomosis of its branches with the right lower pulmonary vascular network. Bronchoscopy showed nodular protrusion of the bronchial mucosa with a local scar. Selective embolization of the bronchial artery was performed to stop bleeding. One month after the first intervention, the symptoms of hemoptysis recurred. A computed tomography angiogram (CTA) showed another tortuous and dilated feeding artery in the right lower lung, which was an abnormal ascending branch of the inferior phrenic artery (IPA). The results of angiography were consistent with the CTA findings. The IPA was found to be another main supplying artery, which was not considered during the first intervention. Finally, the IPA was also treated by microsphere embolization combined with coil interventional closure. During the one-year follow-up, the patient never experienced hemoptysis. CONCLUSION: The supplying arteries of the bleeding lesion in children with BDD may originate from multiple different aortopulmonary collateral arteries, and the IPA should be considered to reduce missed diagnosis. CTA is a noninvasive radiological examination for the screening of suspected vessels, which shows a high coincidence with angiography, and can serve as the first choice for the diagnosis of BDD.

Pediatric bronchial Dieulafoy's disease with bronchial artery embolization: two case reports.

Background: Bronchial Dieulafoy's disease (BDD) is a vascular malformation characterized by the presence of a dysplastic artery in the bronchial submucosa. It is very rare in children but potentially fatal due to life-threatening hemoptysis. Case Description: An 8-year-old boy and a 6-year-old girl were referred to our hospital with recurrent moderate to massive hemoptysis. Intraluminal protrusions with a tendency to bleed were found by bronchoscopy in both patients. Computed tomography angiography (CTA) revealed an abnormal bronchial artery in one patient and a small intraluminal nodule with contrast enhancement in the other. An enlarged bronchial artery and bronchial-to-pulmonary fistulae corresponding to the lesion site were detected by bronchial arteriography in both patients. Based on the radiological findings, the diagnosis of BDD was established. Subsequent bronchial artery embolization (BAE) was successful, and no recurrence of hemoptysis was observed during the 15- to 18-month follow-up. Conclusions: Our cases highlighted the importance of considering BDD in the context of hemoptysis and endobronchial protrusion in children. Bronchial arteriography plays a critical role in diagnosis, especially in cases where CTA does not reveal vascular malformations. Early identification is essential as biopsy is contraindicated. BAE may be an appropriate treatment to improve the prognosis of children with BDD.

Dieulafoy's Lesion of the Duodenum: A Rare and Fatal Cause of Gastrointestinal Bleed.

Dieulafoy's lesion (DL) is an unusual cause of recurrent gastrointestinal bleeding that can be fatal. It can occur in various parts of the gastrointestinal (GI) tract, most commonly located in the stomach, especially at the level of lesser curvature; however, it can occur in other parts, including the colon, esophagus, and duodenum. A duodenal Dieulafoy lesion is characterized by the presence of a larger-caliber artery that protrudes through the GI mucosa and can lead to massive hemorrhage. The exact cause of DL is yet to be determined. Clinical presentation includes painless upper GI bleeding, including melena, hematochezia, and hematemesis, or rarely iron deficiency anemia (IDA); however, most of the patients are asymptomatic. Some patients also have non-gastrointestinal comorbidities such as hypertension, diabetes, and chronic kidney disease (CKD). The diagnosis is established by esophagogastroduodenoscopy (EGD), which includes the presence of micro pulsatile streaming from a mucosal defect, the appearance of a fresh, densely adherent clot with a narrow point of attachment to a minute mucosal defect, and the visualization of a protruding vessel with or without bleeding. Initial EGD can be non-diagnostic due to the relatively small size of the lesion. Other diagnostic modalities include endoscopic ultrasound and mesenteric angiography. The treatment of duodenal DL includes thermal electrocoagulation, local epinephrine injection, sclerotherapy, banding, and hemoclipping. We present here a case of a 71-year-old female who had a history of severe IDA requiring multiple blood transfusions and intravenous iron in the past and was found to have duodenal DL.

Endobronchial lesion in an adolescent with hemoptysis biopsy or not to biopsy?

An 11-year-old girl was brought with complaints of recurrent massive hemoptysis. A computerized tomography (CT) of the chest showed ground glass opacities on the right lower lobe, and a CT angiography showed hypertrophied right pulmonary artery. Flexible bronchoscopy revealed a sessile friable lesion in the right lower lobe, raising suspicion of either a tumor or a vascular malformation. An endobronchial ultrasound (EBUS) revealed a cystic lesion in the submucous plane, with vascularity noted on Doppler mode. This confirmed the diagnosis of bronchial Dieulafoy disease. A bronchial angiography revealed a vascular malformation overlying the lesion with a bronchopulmonary shunt, which was ligated. This case demonstrates the importance of EBUS in endobronchial lesions, to avoid biopsy of a vascular malformation.

A case of bronchial Dieulafoy disease and literature review.

OBJECTIVE: Bronchial Dieulafoy's disease (BDD) is a rare disease that causes massive hemoptysis. This paper reports a case of BDD treated surgically. At the same time, we summarize the data of BDD patients reported in domestic and foreign literature to improve the understanding, diagnosis and treatment of this disease. METHODS: A case of BDD with hemoptysis during bronchoscopy was reported. In addition, we searched for "bronchial Dieulafoy disease" through Pubmed, Web of Science, CNKI and Wanfang databases, covering the literature related to BDD that was definitely diagnosed or highly suspected from January 1995 to December 2021, and summarized the clinical characteristics, chest imaging, bronchoscopic manifestations, angiographic characteristics, pathological characteristics, treatment and outcome of patients. RESULTS: The patient was a 68 year old male. Tracheoscopy revealed nodular and mass like changes in the basal segment of the left lower lobe, which appeared massive hemorrhage when touching the surface. The computed tomography angiophy of the bronchial artery confirmed that the branches of the left bronchial artery were tortuous and dilated, and then the left lower lobe of the lung was resected. During the operation, 3 thick tortuous nutrient artery vessels were sent out from the descending aorta, and 1 thick tortuous nutrient artery was sent out from the autonomic arch. All of them were ligated and cut. The pathology after the operation was in accordance with BDD; The patient did not have hemoptysis after discharge and is still under follow-up. The database identified 65 articles from January 1995 to December 2021. After removing repeated reports, meetings, incomplete information and nursing literature, 60 articles were included to report 88 cases of BDD. BDD can occur at all ages, with a male to female ratio of about 1.6:1. It mainly starts with hemoptysis, and can also be seen due to cough, infection, and respiratory failure; Inflammatory changes such as pulmonary patch shadow, exudation shadow and ground glass shadow of pulmonary hemorrhage were more common in chest imaging; The diagnosis of BDD is mainly based on the bronchoscopy, bronchial angiography and pathological findings of surgical or autopsy specimens. Bronchoscopic findings were mostly non pulsating, smooth nodular or mucosal processes. Bronchial angiography mainly showed tortuous dilatation of bronchial artery, and the lesions were mainly located in the right bronchus, more from the bronchial artery; Diagnosis depends on pathology, showing submucosal expansion of bronchus or abnormal artery rupture and bleeding; 54 cases underwent selective bronchial artery embolization, 39 cases underwent pulmonary lobectomy, 66 cases improved, and 10 cases died (all of them were caused by massive hemorrhage during bronchoscopic biopsy). CONCLUSION: BDD is rare, but may cause fatal massive hemoptysis. Bronchial angiography is considered to be an effective method to diagnose BDD. Since pathological biopsy may lead to fatal bleeding, the necessity of pathological diagnosis remains controversial. Interventional and surgical treatment plays an important role in patients with cough accompanied by massive hemoptysis.

Research advances in Dieulafoy's disease of the bronchus (Review).

Dieulafoy's disease is characterized by abnormal submucosal arteries and results in acute luminal hemorrhage. Dieulafoy's lesions can also be found in the submucosa of the bronchus. Due to its low incidence rate and non-specific clinical symptoms, Dieulafoy's disease is easy to overlook, but can lead to massive bleeding and high rates of mortality. Therefore, improvements in the understanding of the disease are necessary. The awareness of the disease and associated diagnostic and treatment techniques have continued to improve, and thus, an increasing number of cases of Dieulafoy's disease of the bronchus have been reported. In the present review, 74 cases of Dieulafoy's disease are summarized. New technologies such as endobronchial ultrasound, narrow-band imaging, angiography and argon plasma treatment have been found to be increasingly applied to diagnose and treat Dieulafoy's disease of the bronchus. Therefore, the primary focus of this systematic review is to highlight advances in the diagnosis and treatment of bronchial Dieulafoy's disease.

Hemorrhage in a patient with Bronchial Dieulafoy's disease and associated pulmonary fibrosis: A case report.

Background: Bronchial Dieulafoy's disease (BDD) is a rare vascular anomaly that was first described in 1995. The main symptom is recurrent hemoptysis. It can be diagnosed through angiography, bronchoscopy, and sometimes histology and endobronchial ultrasound scan (EBUS). Treatment includes embolization and surgery. Case presentation: A 77-year-old male with dyspnea and CT scan revealing an interstitial pattern underwent bronchoscopy for bronchoalveolar lavage (BAL). During bronchoscopy, a protruding white non-pulsatile lesion was biopsied. The biopsy triggered a massive hemorrhage, which required an embolization procedure. Bronchial Dieulafoy's disease was diagnosed. There was no need for surgery in this case. The interstitial pattern was diagnosed as idiopathic pulmonary fibrosis. Conclusions: This report describes a novel case of BDD leading to bronchial hemorrhage. Considering the endoscopic differential diagnosis, including rather frequent carcinoid tumor and broncholithiasis, we highlight the need for extreme caution when considering endoscopic biopsy of protruding white lesions. Indeed, biopsy - or even contact - with a BDD lesion is frequently associated with massive hemorrhage. According to our review, BDD is the most hemorrhage-prone lesion when biopsied, associated with significant bleeding in 90% of cases and 30% mortality, compared with significant bleeding in only 2.6% of carcinoid tumors and 3.1% of broncholithiasis cases.This case of BDD is also original since associated with idiopathic pulmonary fibrosis. It is to our knowledge the first time that such an association has been reported.

Massive gastrointestinal haemorrhage caused by pancreatic pseudocyst complicated with Dieulafoy's disease in a child: A case report and review of the literature.

Background: Pancreatic pseudocyst (PPC) with massive gastrointestinal bleeding is rare, especially in children. Inadvertent intraoperative examination and damage to the gastric mucosa and malformed blood vessels by the fluid content of PPC can lead to massive bleeding, which may endanger the patient's life. Case presentation: Here, we present a case of an 8-year-old boy who was diagnosed with a massive gastrointestinal haemorrhage caused by PPC complicated with Dieulafoy's disease. At his first admission, his complaint was being hit to the stomach by the handlebar while riding bicycle 24 h before admission. After being hospitalized, he was diagnosed with pancreatic injury by abdominal CT. Conservative treatment lasted for 1 month in the Department of Pediatric Surgery. Then, a pancreatic pseudocyst was formed. Under the guidance of ultrasonic endoscopy, cyst puncture and drainage of pseudocysts through the gastric wall were performed. Unexplained hematemesis occurred 8 days after surgery. Emergency gastroscopy was performed, and abnormal submucosal vascular haemorrhage was found at the gastric fundus. Gastric Dieulafoy's disease was diagnosed. The boy underwent gastroscopic titanium clipping of abnormal arteries. He had no complications during the 3-month follow-up. Then, the patient returned to the hospital, and the stent was removed under endoscopy. No bleeding was found, and the patient was discharged. The patient recovered smoothly and was followed up for half a year without any complications, and hematological indicators were normal. Conclusion: Endoscopic ultrasonography-guided gastric puncture and internal drainage of cysts is a safe and effective surgical method for the treatment of pancreatic pseudocysts. However, at the same time, it is necessary to thoroughly and carefully explore the stomach cavity to prevent adverse consequences caused by a missed diagnosis of gastric Dieulafoy's disease or other abnormal abnormalities.

Huge racemose hemangioma of the bronchial artery with arterial supply via the right coronary artery and left internal thoracic artery.

A 79-year-old male with bronchiectasis was referred to our clinic because of mild chest tightness on exertion. He had no history of hemoptysis. An electrocardiogram showed ST segment depression in leads V5-6. Multi-detector contrast-enhanced computed tomography revealed no significant stenosis in either coronary artery; however, a huge racemose hemangioma of the bronchial artery (RHBA) was detected. In addition, arterial supply to the RHBA via the right coronary artery (RCA) and the left internal thoracic artery (LITA) was suspected. Adenosine-loading myocardial scintigraphy images revealed segmental hypo-perfusion in the left ventricular inferior wall. Selective bronchial artery angiography revealed the huge RHBA. In addition, both the RCA and LITA provided arterial supply to the RHBA. To the best of our knowledge, this case is the first to show multiple arterial supply resulting in a huge RHBA.

Case Report: A Case of Infant Bronchial Dieulafoy's Disease and Article Review.

Background: Bronchial Dieulafoy's disease (BDD), characterized by constant diameter arterial malformation, is rare, especially among infants. The pathogenesis and clinical features of pediatric patients are unknown. Misdiagnosis and biopsy operations may lead to potential massive hemorrhage, which endangers the patient's life. Case Presentation: Here, we present a case of a 9-month-old boy who was diagnosed with BDD with massive hemoptysis. The boy was cured by embolization of the bronchial artery and was in good health at the 1-year follow-up. In addition, we searched PubMed, Google Scholar, and Web of Science databases using keyword "Bronchial Dieulafoy's Disease (BDD)" and found six additional cases of pediatric BDD. Conclusion: It is still insufficient to draw a conclusion about the origin of the disease. Bronchial angiography and endobronchial ultrasonography are considered promising methods to diagnose Dieulafoy's disease of the bronchus. Bronchoscopy with transbronchial biopsy should not be deployed due to the high risk of fatal hemorrhage. Explicit clinical case reports of BDD are needed to enhance the understanding of this rare disease.

A rare cause of massive hemoptysis in a child: Bronchial Dieulafoy's disease - the first report of transcatheter treatment in pediatric age.

We report a case of bronchial Dieulafoy's disease in the pediatric age. Angio-computed tomography scan and arteriography addressed us to diagnosis. Bronchial endoscopy with biopsy was avoided due to the high risk of developing a life-threatening hemorrhage. Transcatheter embolization of the bleeding bronchial artery was achieved with a MicroPlex® 10 HyperSoft 3D 3.5 mm × 80 mm System (MicroVention, Tustin, CA, USA). Dieulafoy's disease is an extremely rare lesion in the pediatric age, and the small diameter of the bleeding vessels may complicate the percutaneous approach with procedural failure. Currently, the novel thin and soft detachable coils allowed to widen the transcatheter embolization in the pediatric age.

Endoscopic full-thickness resection to treat active Dieulafoy's disease: A case report.

BACKGROUND: At present, minimally invasive endoscopic treatment is mostly used for patients with actively bleeding Dieulafoy's lesions, , as it has the advantages of minimal trauma, short operation time and good hemostatic effect, although bleeding can easily recur postoperatively. Recently, extensive gastric cuneiform resection has been advocated for use in these patients because the constant-diameter artery follows a long path to the gastric mucosa. CASE SUMMARY: A 47-year-old man was admitted to the hospital for repeated hematemesis and black stool, and he was diagnosed with Dieulafoy's disease. We chose a method that not only simulates surgical gastric cuneiform resection but also reduces trauma. We performed enlarged local endoscopic full-thickness resection of the gastric wall and abdominal constant-diameter artery and sutured the gastric wall. Postoperative follow-up showed that the constant-diameter artery had been resected from the gastric wall, which was confirmed to have no blood flow signals by endoscopic ultrasonography. CONCLUSION: Endoscopic full-thickness resection of the gastric wall and abdominal constant-diameter artery with suturing of the gastric wall has demonstrated potential as a new treatment for Dieulafoy's disease.

A rare and fatal respiratory disease: bronchial Dieulafoy's disease.

A 66-year-old woman had two severe episodes of massive hemoptysis without any premonitory symptoms, with approximately 400-500 ml blood each time. Bronchoscopic exam revealed a smooth and pulsatile protrusion that was approximately 8-10 mm in diameter found at the beginning of the right middle lobe bronchus in the bronchial lumen. The protrusion arose from the surface with absolutely normal mucosa. Selective bronchial arteriography showed that elongated, tortuous, and dilated branches of the bronchial artery in the region of the middle lobe bronchus. Further bronchial arterial embolization (BAE) is recommended, although the patient currently has no active bleeding. Bronchial Dieulafoy's disease (BDD) is a rare and life-threatening disease. Selective bronchial arteriography is a diagnostic tool to detect and locate abnormal arteries. There is no unified guideline or expert consensus on the treatment of BDD. Selective BAE or surgical resection is usually used as a first-line treatment to control hemoptysis. The reviews of this paper are available via the supplemental material section.
