Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is now a standard of care to sample mediastinal lymph nodes and masses with high diagnostic accuracy and low complication rates. However, the procedure has potential complications that might be life-threatening. Here, we present the first case of Propionobacterium acnes (P. acnes) causing mediastinitis following EBUS-TBNA of a subcarinal lymph node.

Histological Data

Abstract Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a standard method for obtaining specimens of mediastinal and hilar lesions, and several types of needle of various sizes and materials are available. This study aimed to compare the utility and safety of two needles, cobalt chromium (CC) and stainless steel (SS), for EBUS-TBNA. Methods: This retrospective study included data of patients who underwent EBUS-TBNA with a 22-gauge needle made from either SS (38 patients, 121 punctures) or CC (39 patients, 145 punctures), and procedure time, histological data, complication rates were compared. Results: There were no significant differences between the groups in the baseline characteristics of the patients or lesions or in the complication rates. Although diagnostic yields in each patient who underwent EBUS-TBNA with the two needle types were similar, significantly shorter procedure time (22 min vs. 26 min, p = 0.007), diagnostic histologic sampling yield in each sample (71.0% vs. 58.7%, p = 0.039), fewer samples with cartilage alone (1.4% vs. 6.6%, p = 0.047) and fewer samples containing cartilage (7.6% vs. 16.5%, p = 0.034) were seen in the CC group compared with that in SS needle group. Conclusion: Compared with SS needles, CC needle for EBUS-TBNA showed significant shorter procedure time and higher ratio of getting diagnostic histological specimens in each sample. This might be because of better ability of CC needle to puncture through the trachea and bronchial cartilage to get appropriate lymph node sampling.

Endobronchial ultrasound-guided transbronchial needle aspiration is becoming the standard of care for mediastinal sampling to diagnose and stage lung cancer. It is considered to be safe and rivals the gold standard, mediastinoscopy, in safety and accuracy. The present article describes a mucosal airway laceration and pneumothorax associated with the procedure.

Abstract Background Endobronchial ultrasound-guided transbronchial needle aspiration is a standard method for obtaining specimens of mediastinal and hilar lesions. Several types of needles of various sizes and materials are available. This study aimed to compare the quality of specimens collected using two needles, cobalt chromium and stainless steel for endobronchial ultrasound-guided transbronchial needle aspiration. Methods This retrospective study included data of patients who underwent EBUS-TBNA with a 22-gauge needle made from either stainless steel (41 lesions, 121 punctures) or cobalt chromium (47 lesions, 145 punctures). Histological data per puncture, diagnostic yield per lesion, procedure time and complication rates were compared. Results There were no significant differences between the groups in the baseline characteristics of the patients or lesions or in the complication rates. The rate of diagnostic histological specimens in each sample (71.0% vs. 58.7%, P = 0.039), fewer samples with cartilage alone (1.4% vs. 6.6%, P = 0.047) and fewer samples containing cartilage (7.6% vs. 16.5%, P = 0.034) were seen in the cobalt chromium needle group than in the stainless steel needle group. In both groups, the rate of specimens that only contained blood clots in each sample and diagnostic yield per lesion were similar, but the procedure time was significantly shorter (22 min vs. 26 min, P = 0.007) in the cobalt chromium needle group. Conclusion Compared with stainless steel needles, cobalt chromium needle for EBUS-TBNA showed lower cartilage contamination and a higher ratio of obtaining diagnostic specimens in each sample. Bronchoscopists should consider using the optimal needle gauges and materials for collecting adequate specimens.

First Case

Abstract Background Primary malignant tumors of the aorta are extremely rare. They are frequently located in the abdominal aorta, followed by the thoracic aorta. Sarcomas are the most common histological type. These tumors originate from the middle or intimal layer, the latter being the most common. Symptoms and radiological findings are generally nonspecific. Since their growth is endovascular, embolic phenomena can occur leading to occlusive signs and symptoms. Case presentation We describe the case of a 75-year-old Hispanic man, a former tobacco smoker, with a history of pain and epigastric tenderness, dysphagia, and weight loss of approximately 6 kg. A thorax computed tomography scan showed a mass within the posterior mediastinum with poorly defined borders and heterogeneous density, located between thoracic vertebra 5–8, with a size of 78 × 53 × 76 mm, with left main bronchus compression. Endobronchial ultrasound-guided transbronchial needle aspiration was performed; it found an extrinsic posterior compression of the left main bronchus with no endobronchial injury. An intimal angiosarcoma of the thoracic aorta was diagnosed. Conclusion Tumors of the aorta are rare and difficult to diagnose; they are a challenge during the diagnosis, since they usually require open surgical procedures. Endobronchial ultrasound-guided transbronchial needle aspiration associated with rapid on-site examination offered, in this case, the possibility of a successful diagnosis, avoiding major procedures. This is the first case reported in the literature of an intimal angiosarcoma of the thoracic aorta diagnosed using endobronchial ultrasound-guided transbronchial needle aspiration.

Acute Pericarditis

A 27-year-old man was diagnosed with inflammatory myofibroblastic tumor, and multiple lymph node and subcutaneous metastases. After several administrations of anti-tumor therapy, he underwent mediastinal lymph node biopsy using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to confirm tumor relapse. Five weeks later, he complained of chest pain, then rapidly developed shock due to acute pericarditis. Although he was treated with antibiotics for anaerobic bacterial infection and cardiac drainage, mediastinal lymph node abscess and pericarditis did not improve. After the surgical procedure, his physical condition dramatically improved and he was treated with another molecularly targeted therapy. Pericarditis associated with EBUS-TBNA is extremely rare. In this case, salvage was achieved by surgical drainage of the lymph node abscess and pericarditis, and long survival was obtained with further administration of anti-tumor treatment.
