Surgical Intervention for Giant Pulmonary Artery Aneurysm in Behcet Disease: A Case Report.

BACKGROUND Pulmonary artery aneurysm (PAA), defined as a pathologic dilatation of the PA greater than 1.5-fold the normal diameter, is a rare complication of Behçet disease. It is due to a weakening of the vessel wall for a great vessels' vasculitis, often asymptomatic and incidentally diagnosed on imaging studies. However, if ignored, it can lead to life-threatening complications such as rupture and massive hemoptysis. We report the case of a giant fast-growing PAA in a young patient with a history of Behçet disease in which an inadequate follow-up and poor patient information could had led to life-threatening complications. CASE REPORT A 37-year-old man with a history of Behçet disease presented to our Emergency Department with hemoptysis due to a right inferior lobar artery aneurysm measuring 52×33 mm. The aneurysm was detected years before, measuring 18 mm, but the patient and physicians missed the subsequent follow-up. After several attempts at embolization, the multidisciplinary board suggested to proceed with surgical intervention. Surgery was performed with an extracorporeal circulation system kept on stand-by due to the high hemorrhagic risk. By opening the fissure, the dilatation of the inferior lobar artery was clearly identified up to the origin of the middle lobar branch. Thus, a lower-middle bilobectomy was performed after the introduction of a suction cannula in the aneurysm, which facilitated its emptying and the subsequent maneuvers. CONCLUSIONS PAA is a rare disease, generally treated with medical therapy or interventional procedures. However, giant and fast-growing aneurysms are more likely to entail complications and often required immediate treatment. In this case, primary surgical intervention with a pulmonary bilobectomy appeared mandatory to avoid life-threatening events.

Xanthoma of rib: a case report and review of the literature.

BACKGROUND: Xanthomas are well-circumscribed benign proliferative lesions seen mainly in soft tissues. Usually, they are found in hyperlipidemia and familial hyperlipoproteinemia. Histologically, are characterized by macrophage-like mononuclear cells, multinucleated giant cells and abundant foam cells. The bone involvement, however, is notoriously rare and rib localization is extremely rare. CASE PRESENTATION: A 55-year-old man performed a chest X-ray and a subsequent chest Computed Tomography scan showing a rib lesion that was surgically removed and a diagnosis of rib xanthoma was made. The patient presented an unknown condition of hyperlipidemia. CONCLUSION: Rib xanthoma can be discovered accidentally and can be helpful in identifying an unrecognized condition of hyperlipidemia.

Coaxial Drainage versus Standard Chest Tube after Pulmonary Lobectomy: A Randomized Controlled Study.

Chest tubes are routinely inserted after thoracic surgery procedures in different sizes and numbers. The aim of this study is to assess the efficacy of Smart Drain Coaxial drainage compared with two standard chest tubes in patients undergoing thoracotomy for pulmonary lobectomy. Ninety-eight patients (57 males and 41 females, mean age 68.3 ± 7.4 years) with lung cancer undergoing open pulmonary lobectomy were randomized in two groups: 50 received one upper 28-Fr and one lower 32-Fr standard chest tube (ST group) and 48 received one 28-Fr Smart Drain Coaxial tube (SDC group). Hospitalization, quantity of fluid output, air leaks, radiograph findings, pain control and costs were assessed. SDC group showed shorter hospitalization (7.3 vs. 6.1 days, p = 0.02), lower pain in postoperative day-1 (p = 0.02) and a lower use of analgesic drugs (p = 0.04). Pleural effusion drainage was lower in SDC group in the first postoperative day (median 400.0 ± 200.0 mL vs. 450.0 ± 193.8 mL, p = 0.04) and as a mean of first three PODs (median 325.0 ± 137.5 mL vs. 362.5 ± 96.7 mL, p = 0.01). No difference in terms of fluid retention, residual pleural space, subcutaneous emphysema and complications after chest tubes removal was found. In conclusion, Smart Drain Coaxial chest tube seems a feasible option after thoracotomy for pulmonary lobectomy. The SDC group showed a shorter hospitalization and decreased analgesic drugs use and, thus, a reduction of costs.

Left uniportal VATS for lung decortication after chemical pleurodesis under spontaneous breathing in patient with lymphangiomyomatosis.

Pneumothorax can be the first symptom of lymphangioleiomyomatosis. Patients with lymphangioleiomyomatosis have a higher risk of recurrence of pneumothorax. Chemical pleurodesis is a viable option to treat the recurrence, but in rare cases, it is not the solution. We present the case of a patient with lymphangioleiomyomatosis undergoing a talc poudrage via video-assisted thoracoscopic surgery for pneumothorax that failed to reexpand the lung. We proposed to the patient a surgical approach to debride the lung parenchyma with the patient under deep sedation with spontaneous breathing. The patient was discharged on the 5th postoperative day. The chest computed tomography scan showed complete lung reexpansion.    We advocate that video-assisted thoracoscopic surgery in patients who are awake is a feasible surgical option that permits the restoration of physiological lung expansion in selected patients who underwent chemical pleurodesis and minimizes the risk of one-lung ventilation.

Use of Ceftazidime-Avibactam and Ceftolozane-Tazobactam After Lung Transplantation.

INTRODUCTION: After lung transplantation (LTx), infections caused by multidrug-resistant (MDR) bacteria are frequent and difficult to treat. Some new antibiotics seem to be effective in treating these infections. MATERIAL AND METHODS: We describe our experience in treatment of Klebsiella pneumoniae MDR and Pseudomonas aeruginosa MDR infections with ceftazidime-avibactam (CEF-AVI) and ceftazidime-tazobactam (CEFT-TAZ) in patients who underwent LTx. RESULTS: In 3 patients who underwent double LTx and in 4 patients who underwent single LTx, strains of K. pneumoniae and P. aeruginosa were isolated from bronchoalveolar lavage. All patients showed worsening of respiratory functions, increasing in inflammation indexes, and, in some cases, onset of pulmonary consolidation. P. aeruginosa was treated with CEFT-TAZ for 10 days average (7-15 days) and K. pneumoniae with CEF-AVI for 14 days average (4-24 days). One patient developed a septic state caused by K. pneumoniae, requiring 24 days of therapy. None had shown side effects caused by drugs administration. One patient died after 15 days from lung transplant owing to primary graft dysfunction. CONCLUSIONS: CEF-AVI and CEFT-TAZ seems to be effective in treatment of infections caused by MDR bacteria after lung transplant.

Inflammatory Myofibroblastic Tumor After Lung Transplant-A Rare and Aggressive Complication: A Case Report.

INTRODUCTION: Malignant diseases are well-known complications after lung transplantation (LT). Among these, inflammatory myofibroblastic tumor (IMT) is a rare neoplasm with a not well-known and often aggressive biological behavior. MATERIAL AND METHODS: We hereby describe 2 cases of cystic fibrosis patients who underwent bilateral sequential LT (BSLT) complicated by IMT. RESULTS: A 26-year-old man presented a right endobronchial lesion 6 months after BSLT. Two consecutive fiber bronchoscopic biopsies showed granulation tissue. For the persistent lesion growth, the patient underwent a transthoracic biopsy showing histologic diagnosis of IMT. Therefore, he underwent to right pneumonectomy that was unfortunately complicated after 6 months with a late bronchopleural fistula and empyema with exitus 6 months later. A 31-year-old woman 1 year after BSLT presented with a left voluminous pleural-parenchymal lesion; the histologic examination after biopsy revealed an IMT. She underwent a removal of the lesion with a macroscopic R0 resection. Histologic, immunophenotypic, and cytogenetic examinations showed a strong overexpression of anaplastic lymphoma kinase requiring biological adjuvant therapies; however, the patient refused it. Four years later, she presented a recurrence treated with debulking procedure and adjuvant radiotherapy. At last follow-up, the patient was alive with stable disease and optimal graft function. CONCLUSIONS: Although IMT is a rare complication after lung transplant, to obtain a careful diagnosis, an early and aggressive treatment is mandatory.

[Stratification of cardiovascular risk in patients with non-traumatic chest pain in the emergency department. Perspectives of the Heart Risk Score in patients with acute coronary syndrome.] / Stratificazione del rischio cardiovascolare nei pazienti con dolore toracico non traumatico nel dipartimento d'emergenza.

INTRODUCTION: Acute chest pain (CP) is a potentially related both to acute coronary syndrome and to other morbidities; this means that 2%-10% patients with cardiogenic CP are improperly discharged from the Emergency Room (ER). In order to identify risk to develop cardiovascular (CV) events in patients admitted to ER with CP, we used Heart Risk Score (HRS). MATERIALS AND METHODS: We included 165 patients referred to the ER for non-traumatic acute CP. We retrospectively analyzed clinical records from ER and Chest Pain Unit (CPU). We calculated HRS, then we analyzed HRS sensitivity and specificity, and correlated raw data of all variables with Spearman's analysis. RESULTS: Diagnosis of ischemic heart disease was made in 53.9% patients referring CP. The remaining patients were affected by other non-ischemic heart disease (35.5%), gastro-esophageal disease (32.3%), pleuro-pulmonary pathology (15.8%), musculoskeletal disorders (10.5%), and panic attacks (6.6%), respectively. Patients affected by coronaropathy had hypertension (80.9%), history of cardiopathy (61.8%), chronic smoking (49.4%), hypercholesterolemia (37.0%) , diabetes (33.7%) and obesity (24.7%). Low, medium and high HRS patients were 15.7%, 59.4% and 24.8%, respectively. Risk of CV events increased with the increase of the score. The negative predictive value (NPV) in low score was 92.3%. In high score, sensitivity and specificity were 94.7% and 82.7%, respectively. Finally, the following positive Spearman's correlations were found: HRS vs its risk variables, including individual risk variables, ischemic heart disease vs CV risk factors, history of ischemic cardiac disease vs risk factors, number of stenotic vessels vs risk factors (significance values: p <0.05). DISCUSSION: HRS contains history of all risk factors for coronary artery disease and considers mild ECG and troponin alterations, giving the possibility to undertake the most appropriate path for the patient. CONCLUSIONS: Our work evidences relevance, reliability and ease of use of HRS in CV risk stratification in the emergency department, giving an important contribution in the evaluation of individuals who are likely to experience ischemic heart disease.
