Lung resections combined with vena cava replacement.

Resection and reconstruction of the superior vena cava in patients with lung cancer is still considered a surgical challenge; the numerous problems related to patient selection, the choice of the most appropriate surgical strategy and technique, the most suitable material for replacement, and the number of potential complications definitively show an impact on short-term outcome and long-term prognosis. However, with the appropriate indications and surgical technique, a clear benefit has been documented in a select group of patients with lung cancer.

Left atrial size predicts the onset of atrial fibrillation after major pulmonary resections.

Objectives: Atrial fibrillation (AF) is a frequent complication after pulmonary resections. Notwithstanding prevention and early treatment it may show a negative impact on the outcome. We assessed the role of echocardiographic variables to predict the onset of this complication.

Anterior approach to the thoracic spine.

An anterior approach affords the spine surgeon excellent visualization and access to the anterior thoracic spine, the vertebral bodies, intervertebral disks, spinal canal, and nerve roots. This approach is currently used in the surgical treatment of thoracic disk disease, vertebral osteomyelitis or discitis, fractures and tumors of the vertebral bodies, allowing for proper decompression of neural elements and spine stabilization. Over a 10-year period in a single institution, a total of 142 patients with a mean age of 49.

Thymoma and thymic carcinoma.

Thymoma and thymic carcinoma are an extremely heterogeneous group of neoplastic lesions with an exceedingly wide spectrum of morphologic appearances. They show different presentations with a variable and unpredictable evolution ranging from an indolent non-invasive attitude to a highly infiltrative and metastasising one. Prognosis can be predicted on the basis of a number of variables, mainly staging, the WHO histological pattern and diameter of the tumour.

Thoracoscopic resection of mediastinal bronchogenic cysts in adults.

Objective: Bronchogenic cysts are uncommon congenital anomalies of foregut origin usually located within the mediastinum and the lung and rarely diagnosed in adults. Surgical excision is recommended to establish diagnosis based on histologic examination, alleviate symptoms if present, and prevent future complications. Thoracoscopic approach is becoming the primary therapeutic option.

Long-term Doppler echocardiographic evaluation of the right heart after major lung resections.

Objective: The effects of major lung resections on cardiac function in the medium and long term have not been thoroughly evaluated. We have studied right heart function with serial Doppler echocardiography in patients undergoing lobectomy and pneumonectomy during 4 years of follow-up after surgery.

Methods: Thirty-six patients undergoing lobectomy and 15 receiving pneumonectomy were evaluated with one- and two-dimensional Doppler standard transthoracic echocardiography before surgery and 1 week, 3 months, 6 months, 1 year, and 4 years postoperatively.

Pleurodesis with an autologous blood patch to prevent persistent air leaks after lobectomy.

Objective: Air leakage after pulmonary lobectomy is a well-known problem often contributing to extended hospitalization. Many techniques have been proposed to prevent and treat air leakage, but none have been proved incontrovertibly effective. We evaluated the role of an autologous blood patch after pulmonary lobectomy.

Successful treatment with one-way endobronchial valve of large air-leakage complicating narrow-bore enteral feeding tube malposition.

Tracheopulmonary intubation is the most common misplacement site for narrow-bore feeding tube and it might be associated with severe pleuro-pulmonary complications. A 38-year-old female with a severe bilateral pneumonia and acute respiratory insufficiency was admitted in the ICU, intubated, and mechanically ventilated. Few hours after the insertion of a narrow-bore feeding tube the patient's oxygen saturation dropped with hypotension and tachycardia.

Laminin alpha2 chain-positive vessels and epidermal growth factor in lung neuroendocrine carcinoma: a model of a novel cooperative role of laminin-2 and epidermal growth factor in vessel neoplastic invasion and metastasis.

Capillaries expressing the laminin alpha2 chain in basement membranes may be considered early developing vessels in normal and neoplastic human tissues. Therefore, we investigated whether up-regulation of this extracellular matrix protein favors transendothelial migration of neoplastic cells and then metastasis. In lung small and large cell neuroendocrine carcinomas, which exhibit a stronger metastatic tendency among carcinomas, laminin alpha2 chain-positive vessels were more numerous than in carcinoid tumors and supraglottis, breast, and lung non-small cell carcinomas, suggesting a direct relationship between these vessels and metastasis.

Operative endoscopy of the airway with the old-fashioned esophageal dilators.

Bronchial dilation is usually required to treat a number of disorders; the most frequent are complications after airway surgery, including lung transplantation, stenosis after radiotherapy, and compression by an extraluminal mass. The procedure is performed by forcing the tip of a rigid bronchoscope through the stenosis using barrels of increasing size; however, when there is a clear discrepancy between the caliber of the rigid instrument and the stenosis, the first step may be difficult. In such cases, we have successfully employed two types of old-fashioned esophageal dilators rescued from the armamentarium of our endoscopy unit.

Transsternal thymoma resection.

Thymomas are traditionally regarded as tumours arising from the epithelial cells of the thymus. They are the second most frequent mediastinal tumour in the adult and show a variable clinical presentation and clinical course. Complete surgical resection should be the gold standard.

Operative and non-operative treatment of benign subglottic laryngotracheal stenosis.

Objective: Surgery is the first line of treatment for laryngotracheal stenosis; Montgomery tube or permanent tracheostomy have been so far the only alternatives. Nd-YAG laser resection and indwelling endotracheal stents have rarely been used in subglottic stenosis for anatomic and technical reasons. We have used the latter approach to optimize the timing of surgery or to achieve palliation without tracheostomy.

Bullectomy is comparable to lung volume reduction in patients with end-stage emphysema.

Objectives: Emphysema is one of the most prevalent disabling diseases, not modified by current medical treatment and physical rehabilitation. Lung transplantation is an effective clinical option in end-stage emphysema but it is available only for a limited number of patients. Bullectomy and lung volume reduction represent other surgical options to improve symptoms and exercise tolerance in selected patients.
