Pulmonary sequestration in adulthood: clinical-morphological study.

OBJECTIVES: The aim of the study was to evaluate pulmonary sequestration (PS). We report on location, blood supply, histology, clinical manifestation, and surgical treatment of PS, as well as on postoperative course in patients with PS. BACKGROUND: PS is a rare congenital defect of the lower respiratory tract, it represents locus minoris resistentiae of the body. Occasionally, PS is diagnosed for the first time in adulthood. METHODS: We evaluated 7 cases of PS treated at the Centre of Thoracic Surgery in Vysné Hágy, Slovakia, between years 2013 and 2020. RESULTS: Four of our seven patients were asymptomatic; the PS was found incidentally upon chest imaging. Three patients had recurrent bronchopneumonia related specifically to the intralobar type of sequestration. The most significant complication, observed in a singular patient, was a life-threatening episode of haemoptysis, requiring urgent surgical intervention. In the other 6 cases, the sequestra were surgically resected during the period when they were asymptomatic. and their sputum was confirmed negative upon microbiological examination. Anatomical resection of the affected pulmonary lobe by thoracotomy was the most common type of operation performed (4 cases, n = 7). There was no surgical mortality. CONCLUSION: To prevent complications, it is crucial to perform surgical treatment for pulmonary sequestration in patients who have sufficient functional capacity (Tab. 2, Fig. 4, Ref. 30).

Synchronous computed tomography-guided percutaneous biopsy and microwave ablation for highly suspicious malignant lung ground-glass opacities adjacent to mediastinum.

BACKGROUND: This retrospective study aimed to assess the safety and efficacy of synchronous biopsy and microwave ablation (MWA) for highly suspected malignant lung ground-glass opacities (GGOs) adjacent to the mediastinum (distance ≤10 mm). MATERIALS AND METHODS: Ninety patients with 98 GGOs (diameter range, 6-30 mm), located within 10 mm of the mediastinum, underwent synchronous biopsy and MWA at a single institution from 1 May 2020, to 31 October 2021 and were enrolled in this study. Synchronous biopsy and MWA involving the completion of the biopsy and MWA in a single procedure was performed. Safety, technical success rate, and local progression-free survival (LPFS) were evaluated. The risk factors for local progression were calculated using the Mann-Whitney U test. RESULTS: The technical success rate was 97.96% (96/98 patients). The LPFS rates at 3, 6, and 12 months were 95.0%, 90.0%, and 82.0%, respectively. The diagnostic rate of biopsy-proven malignancy was 72.45% (n = 71/98). Invasion of lesions into the mediastinum was a risk factor for local progression (p = 0.0077). The 30-day mortality rate was 0. The major complications were pneumothorax (13.27%), ventricular arrhythmias (3.06%), pleural effusion (1.02%), hemoptysis (1.02%), and infection (1.02%). Minor complications included pneumothorax (30.61%), pleural effusion (24.49%), hemoptysis (18.37%), ventricular arrhythmias (11.22%), structural changes in adjacent organs (3.06%), and infection (3.06%). CONCLUSIONS: Synchronous biopsy and MWA was effective for treating GGOs adjacent to the mediastinum without severe complications (Society of Interventional Radiology classification E or F). Invasion of lesions into the mediastinum was identified as a risk factor for local progression.

Is VATS suitable for lung diseases with hemoptysis? Experience from a hemoptysis treatment center in China.

BACKGROUND: Surgery is crucial in the treatment of the potentially fatal pulmonary hemoptysis condition. Currently, most patients with hemoptysis are treated by traditional open surgery (OS). To illustrate the effectiveness of video-assisted thoracic surgery (VATS) for hemoptysis, we developed a retrospective study of surgical interventions for lung disease with hemoptysis. METHODS: We collected and then analysed the data, including general information and post-operative outcomes, from 102 patients who underwent surgery for a variety of lung diseases with hemoptysis in our hospital between December 2018 and June 2022. RESULTS: Sixty three cases underwent VATS and 39 cases underwent OS. 76.5% of patients were male (78/102). Comorbidities with diabetes and hypertension were 16.7% (17/102) and 15.7% (16/102) respectively. The diagnoses based on postoperative pathology included aspergilloma in 63 cases (61.8%), tuberculosis in 38 cases (37.4%) and bronchiectasis in 1 case (0.8%). 8 patients underwent wedge resection, 12 patients underwent segmentectomy, 73 patients underwent lobectomy and 9 patients underwent pneumonectomy. There were 23 cases of postoperative complications, of which 7 (30.4%) were in the VATS group, significantly fewer than 16 (69.6%) in the OS group (p = 0.001). The OS procedure was identified as the only independent risk factor for postoperative complications. The median (IQR) of postoperative drainage volume in the first 24 h was 400 (195-665) ml, which was 250 (130-500) ml of the VATS group, significantly less than the 550 (460-820) ml of the OS group (p < 0.05). The median (IQR) of pain scores 24 h after surgery was 5 (4-9). The median (IQR) of postoperative drainage tube removal time was 9.5 (6-17) days for all patients, and it was 7 (5-14) days for the VATS group, which was less than 15 (9-20) days for the OS group. CONCLUSION: VATS for patients with lung disease presenting with hemoptysis is an effective and safe option that may be preferred when the hemoptysis is uncomplicated and the patient's vital signs are stable.

[Surgical Case of Bronchial Mucoepidermoid Carcinoma Safely Diagnosed by Enucleation Under the Bronchoscopy After Bronchial Arterial Embolization].

A 28-year-old male presented to our hospital with hemoptysis and his chest computerized tomography (CT) showed the right middle and lower lobe atelectasis due to the tumor of right intermediate bronchial trunk. To reduce the blood flow to the tumor, bronchial arterial embolization was performed and the tumor was resected using Cryoprobe with a flexible endobronchial scope. Thus, we could observe the tumor localization and diagnose before the surgical procedure. We performed the right sleeve middle lobectomy and the right lower lobe was safely preserved.

[Peripheral Pulmonary Artery Aneurysm with Internal Thoracic Artery-Pulmonary Artery Shunt].

An 82-year-old woman with past history of pulmonary nontuberculous mycobacterial infection complained of hemoptysis and was pointed out the strongly stained nodule in the middle lobe of the right lung on chest enhanced computed tomography (CT), which was suggested to be peripheral pulmonary artery aneurysm. Angiography of the right internal thoracic artery (RITA) revealed the peripheral pulmonary artery aneurysm with the shunt from the branch of the RITA, which was considered to be the cause of hemoptysis. Transcatheter arterial embolization was performed for the branch of the RITA 2 times, however, the hemoptysis recurred again after 5 months. Therefore, after the third embolization for the RITA, the right middle lobectomy with amputation of the shunt vessel was performed. The patient has been well without hemoptysis for one year and 6 months after the surgery.

Intrapulmonary sequestration with destructive pneumonia and life-threatening hemoptysis in an adult patient: a case report.

The article reports the case of a patient with bronchopulmonary sequestration complicated by destructive actinomycotic inflammation leading to life-threatening hemoptysis. It was an adult patient with the history of repeated right-sided pneumonia the cause of which had not been investigated in detail in the past. Only hemoptysis, which appeared as a complication, led to a closer investigation of the background of repeated right-sided pneumonia. CT scan of the chest revealed a lesion of the middle lobe of the right lung with anomalous vascularization - compatible with intralobar sequestration. Initially, conservative antibiotic treatment of pneumonia was provided at a local clinic. Embolization of the afferent vessels of the sequestrum was indicated due to persistent hemoptysis; this led to a reduction of its blood supply, proven by a follow-up CT examination of the chest. Clinically, the hemoptysis subsided. Three weeks later, the hemoptysis reocurred. The patient was acutely hospitalized at a specialized thoracic surgery department where shortly after admission, hemoptysis progressed to life-threatening hemoptea. Urgent middle lobectomy of the right lung was approached via thoracotomy to treat the source of bleeding. The case describes unrecognized bronchopulmonary sequestration as a possible cause of recurrent ipsilateral pneumonia in adulthood; additionally, it emphasizes the possible risks associated with a pathologically altered tissue microenvironment of pulmonary sequestration, and the need for surgical removal in all indicated cases.

Endometriotic lung cyst causing catamenial hemoptysis; a case report and review of literature.

We report a rare case of an endometriotic lung cyst in a 47-year woman with recurrent catamenial hemoptysis. Chest computed tomography (CT) obtained outside the menstruation in October 2019 revealed a cystic lesion (2.5 cm) located in the right inferior lobe near the distal esophagus and the inferior pulmonary vein. Compared to CT abdomen in May 2019, this lesion had increased with a larger volume and a thicker wall. An endometrial lung cyst was suspected as episodes of hemoptysis no longer occurred after initiating hormonal treatment with nomegestrol acetate. Exploratory video-assisted thoracoscopic surgery with wedge resection of the cyst was performed. Histopathologic examination confirmed the diagnosis of an endometriotic cystic lesion. Postoperative course was uneventful with no further symptoms since then.

Hybrid Management of an Aortobronchial Fistula after Patch Aortoplasty for Aortic Coarctation in a Patient with SARS-CoV-2 Pneumonia: Case Report and Review of the Literature.

Aortobronchial fistula is a rare cause of repeated hemoptysis and a potentially fatal condition if left untreated. We present the case of a 40-year-old man with repeated hemoptysis, excessive cough, and epistaxis ongoing for several days after SARS-CoV-2 pneumonia diagnosis. The patient had a history of patch aortoplasty for aortic coarctation and aortic valve replacement with a mechanical valve for aortic insufficiency due to bicuspid aortic valve at the age of 24. Computed tomography scan performed at presentation revealed a severely dilated ascending aorta, a thoracic aorta pseudoaneurysm at the site of the former coarctation, an aortobronchial fistula suggested by the thickened left lower lobe apical segmental bronchus in contact with the pseudoaneurysm and signs of alveolar hemorrhage in the respective segment. The patient was treated with thoracic endovascular aneurysm repair (TEVAR) after prior hemi-aortic arch debranching and transposition of the left common carotid artery and subclavian artery through a closed-chest surgical approach. Our case report together with a systematic review of the literature highlight the importance of both considering an aortobronchial fistula in the differential diagnosis of hemoptysis in patients with prior history of thoracic aorta surgical intervention, regardless of associated pathology, and of taking into account endovascular and hybrid techniques as an alternative to open surgical repair, which carries a high risk of morbidity and mortality.

[Emergent Treatment for Life-threating Hemoptysis].

Life-threatening hemoptysis results significant airway obstruction, abnormal gas exchange. When a patient presents with life-threatening hemoptysis, the initial steps are to provide adequate oxygenation and ventilation, secure the airway, position the patient lateral decubitus with bleeding side down, and perform initial treatments to control the bleeding. Bronchoscopy is an important early procedure and can be both diagnostic and therapeutic. For patients who are stable, contrast chest computed tomography (CT) provides diagnostic information before angiography. In most cases, initial measures are successful, allowing time for a more detailed diagnostic investigation and generation of a therapeutic plan. For most patients, arteriography is appropriate for identifying and embolizing a responsible lesion. For patients with refractory life-threatening hemoptysis, repeating previous interventions or evaluating for surgery is appropriate. Patients with aneurysms should be evaluated for urgent surgery.

[An Anastomotic Aneurysm Thirty Years After Open Surgery of the Descending Thoracic Aorta:Report of a Case].

An 86-year-old man was hospitalized urgently to our department because of his worsening hemoptysis. He had undergone open thoracic aortic grafting for the Stanford type B chronic aortic dissecting aneurysm 30 years earlier. Contrast enhanced computed tomography (CT) revealed the distal anastomotic aneurysm, leakage of the contrast medium around the distal anastomotic site. We urgently performed thoracic endovascular aneurysm repair( TEVAR) for the distal anastomotic aneurysm. TEVAR was done under local anesthesia because of his poor respiratory condition due to hemoptysis. He recovered well without hemoptysis. Patients after open aortic surgery are expected to survive longer. Thus, special attention should be paid to the occurrence of anastomotic aneurysms.

Management of Significant Airway Bleeding during Robotic Assisted Bronchoscopy: A Tailored Approach.

Robotic assisted bronchoscopy represents a major turning point in bronchoscopic history. The management strategies to address significant airway bleeding in this "robotic era" are not well documented, and further guidance is required. We present a case report that exemplifies our approach and management strategy using a combined and simultaneous flexible/robotic bronchoscopy if this complication is encountered.

Surgical management of chronic pulmonary aspergillosis in Africa: A systematic review of 891 cases.

Chronic pulmonary aspergillosis (CPA) is an emerging fungal infectious disease of public health importance. We conducted a systematic review of studies reporting the outcomes of patients with CPA managed surgically in Africa. A search of Medline, Embase, Web of Science, Google Scholar and African Journals Online was conducted to identify studies indexed from inception to June 2021 that examined surgical management of CPA in Africa. All articles that presented primary data, including case reports and case series, were included. We excluded review articles. A total of 891 cases (557 males (62.5%), mean age 39.3 years) extracted from 27 eligible studies published between 1976 and 2020 from 11 African countries were included. Morocco (524, 59%) and Senegal (99, 11%) contributed the majority of cases. Active or previous pulmonary tuberculosis was reported in 677 (76.0%) cases. Haemoptysis was reported in 682 (76.5%) cases. Lobectomy (either unilateral or bilateral, n = 493, 55.3%), pneumonectomy (n = 154, 17.3%) and segmentectomy (n = 117, 13.1%) were the most frequently performed surgical procedures. Thirty (4.9%) cases from South Africa received bronchial artery embolisation. Empyema (n = 59, 27.4%), significant haemorrhage (n = 38, 173.7%), incomplete lung expansion (n = 26, 12.1%) and prolonged air leak (n = 24, 11.2%) were the most frequent complications. Overall, 45 (5.1%) patients died. The causes of death included respiratory failure (n = 14), bacterial superinfection/sepsis (n = 10), severe haemorrhage (n = 5), cardiopulmonary arrest (n = 3) and complications of chronic obstructive pulmonary disease (n = 3). The cause of death was either unknown or unspecified in 9 cases. We conclude that surgical treatment had very low mortality rates and maybe considered as first-line management option in centres with experience and expertise in Africa.

The role of computed tomography angiography as initial imaging tool for acute hemorrhage in the head and neck.

OBJECTIVES: Acute hemorrhage in the head and neck (AHNH) is life-threatening due to asphyxiation and hemorrhagic shock. When conservative measures fail, some patients benefit from endovascular therapy (EVT). While CTA is routinely used to localize bleeding and plan EVT in gastrointestinal hemorrhage, the diagnostic value of CTA in AHNH and role of CTA in treatment-planning are uncertain. METHODS: We retrospectively reviewed neck CTAs from June 2015 to October 2018 indicated for AHNH. When performed, digital subtraction angiography (DSA) findings and EVT were documented. Extravasation or pseudoaneurysm on DSA was considered positive for bleed localization. RESULTS: Thirty CTA exams were performed for AHNH in 18 patients (mean age = 56.6, male% = 55.6%). Eleven out of 30 exams (36.7%) had immediate DSA follow-up within 24 h. Etiologies of hemorrhage included malignancy 11/18 (61.1%) and coagulopathy (4/18, 22.2%) among others. CTA reports identified definite or possible source of bleeding in 7/30 (23.3%) exams. Seven out of 7 (100%) patients with definite or possible source of bleeding on CTA underwent DSA and 4/23 (17.4%) patients underwent DSA despite negative CTA. With DSA as the gold standard, CTA had a sensitivity of 70% and a specificity of 100%. CONCLUSIONS: CTA has high specificity and reasonable sensitivity for detecting arterial source of bleeding in patients presenting with AHNH. Patients with negative CTA may avoid catheter angiography in most cases; however, false-negative CTA should not preclude angiography in high-risk patients.

Potential Factors Affected Safety and Efficacy of Transcatheter Plug Closure for Pediatric Hemoptysis with Anomalous Bronchial Arteries.

OBJECTIVE: To evaluate the safety and efficacy of interventional care in pediatric hemoptysis for anomalous bronchial arteries (BAs) and to identify the potential factors resulting in hemoptysis recurrence. METHODS: 20 children complained of hemoptysis were diagnosed with anomalous BAs. All patients received transcatheter plug occlusion in Department of Cardiology, Children's Hospital of Chongqing Medical University. The safety and efficacy were evaluated according to clinical symptoms and images monitoring of enrolled subjects grouped as recurrence group and nonrecurrence group. The potential factors causing hemoptysis recurrence were reviewed and summarized. RESULTS: No deaths were recorded in a follow-up. Otherwise, hemoptysis recurrence was found in 8 subjects for 14 times, accounting for about 40%. Compared with nonrecurrence group, it indicated a statistical significance in hemoglobin levels (P=0.049), mycoplasma pneumonia particle assays (MP-PA) titers (P=0.030), and number of anomalous BAs (P=0.020). Meanwhile, 50% recurrent scenarios were associated with a respiratory infection by microbiological assessment before transcatheter plug occlusion. The repeat occlusion was applied for unclosed BAs leading to visual recurrent hemoptysis, the average interval time of which was 5.4 ± 3.6 mon. CONCLUSION: The data from this retrospective study have shown that transcatheter plug occlusion is a relatively safe procedure with a low mortality. The number of abnormal BAs has been identified as a highly significant predictor of recurrence, and the role of MP and other potential factors should be verified in a multicenter, larger sample size, and randomized controlled trial.

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.

Pulmonary alveolar hemorrhage in a patient with a temporary external ventricular assist device and extracorporeal membrane oxygenation.

Mechanical circulatory support is increasingly used and may bring about unique challenges. Most support systems require systemic anticoagulation and the need for anticoagulation must be balanced against the increased risk for bleeding. We report the case of a young man awaiting heart retransplantation, who was supported with a temporary extracorporeal ventricular assist device with the addition of an oxygenator. He developed hemoptysis that forced the cessation of anticoagulation exposing to increased thromboembolic risk. We discuss this distinct clinical scenario with no clearly defined solution and explore the risks and benefits of the different treatment options.

Outcomes of Pulmonary Artery Embolization and Stent Graft Placement for the Treatment of Hemoptysis Caused by Lung Tumors.

PURPOSE: To evaluate the safety and efficacy of endovascular management of pulmonary artery lesions caused by lung tumors. MATERIALS AND METHODS: Nineteen patients (15 men, 4 women; average age: 60.3 years, range, 51-86 years) treated for massive or recurrent hemoptysis with transarterial pulmonary artery embolization between 2010 and 2016 were included in this multicenter, retrospective study. Inclusion criteria were: patients with lung cancer and at least 1 episode of hemoptysis with a pulmonary artery lesion detected by computed tomography (CT) angiography or after failed bronchial artery embolization. No patient undergoing pulmonary embolization for a lung tumor was excluded. Technical success, clinical success, and complications were recorded. The survival curve was estimated using the Kaplan-Meier method RESULTS: Mean follow-up was 188.1 days (range, 0-1440 days). Primary and assisted technical success rates were 73.7% (14/19) and 84.2% (16/19), respectively. Two patients died during the procedure due to massive hemoptysis and cardiac arrest, and 1 patient was treated with surgery. All patients with technical success achieved clinical success without further bleeding. No complications were noted, and no pulmonary infarction was detected on CT scan during follow-up. Survival rates after embolization at 1 and 3 months were 67% (95% confidence interval [CI]: 40%-90%) and 46% (95% CI: 23%-80%), respectively, with 36.8% (n = 7) of the patients still alive at the end of the study. CONCLUSIONS: Embolization is an effective and safe treatment of lung tumors with pulmonary arterial bleeding.

Pharyngeal Papilloma: a Rare Non-Pulmonary Cause of Hemoptysis.

The most common benign neoplasm of the pharynx is papilloma. It is characterized by bulging brittle lesions, which are pedicled or sessile, whitish-grey or pinkish colour. Progressive hoarseness is the main clinical feature. When the papillomata spread throughout the tracheobronchial tree symptoms such as chronic cough, stridor, dyspnea or acute respiratory distress are mostly present. Hemoptysis as a presenting symptom is exceptionally rare in patients with pharyngeal papillomatosis. Herein, we report a case of pharyngeal papillomatosis in which hemoptysis was the primary clinical manifestation. The clinical and therapeutic aspects of the disease are briefly discussed.

Endobronchial Valve Used as Salvage Therapy in a Mechanically Ventilated Patient with Intractable Life-Threatening Haemoptysis.

Treatment options for intractable life-threatening haemoptysis in mechanically ventilated patients with structural lung disease who do not respond to bronchial artery embolisation (BAE) and who are deemed unfit for surgery are limited. A 26-year-old HIV-positive male with a poorly preserved CD4 count and active pulmonary tuberculosis was intubated and mechanically ventilated for persistent life-threatening haemoptysis. Two attempts at BAE failed, and life-threatening haemoptysis recurred daily for 14 days despite antituberculous therapy. He was deemed unfit for surgery during that period. We proceeded to identify the source of bleeding endoscopically and implanted an endobronchial valve in the left upper lobe bronchus. Following the collapse of the affected lobe, haemoptysis ceased and the patient was promptly liberated from mechanical ventilation. He remained haemoptysis free for the duration of his hospitalisation. Endobronchial valves, therefore, may be a viable option in patients mechanically ventilated with persistent life-threatening haemoptysis in whom all other conventional measures fail and who are considered unfit for surgery.
