Nitinol stent insertion for post-pneumonectomy syndrome.
Post-pneumonectomy syndrome is an unusual condition, that can occur a variable period of time after a patient has had a pneumonectomy. Management of this syndrome has been described using a number of different techniques, often with considerable mortality. We present a case report where this condition was treated successfully by insertion of an expandable Nitinol stent. This is the first time this technique has been described to treat this condition, and we feel it may be the procedure of choice in managing these patients.

A novel anatomy-conforming metallic stent for tracheobronchial stenosis.
A metallic stent for tracheobronchial stenosis provides a possible solution for poststenting complications such as sputum retention. We describe our experience with a novel anatomy-conforming metal stent placement at the carina.. A windowed stent was designed to match the tracheobronchial anatomy. The lateral window was used as a passage from the trachea to the contralateral main bronchus.. Six windowed stents were placed in 6 patients (mean age, 52.3 years). Two patients received an additional short straight stent placed in the contralateral bronchus, forming an overall Y stent at the carina. All patients had immediate relief from respiratory distress, and no sputum retention or stent migration occurred during the subsequent treatment period. Follow-up data showed that 4 patients are still alive. One patient died 2 months after stent placement of postradiation hemoptysis, and another died of metastasis 14 months after stent placement.. This anatomy-conforming metal stent has several advantages and its application in carinal stenosis is both effective and safe.

Malignant tracheobronchial strictures: palliation with covered retrievable expandable nitinol stent.
To evaluate the safety and clinical effectiveness of a covered retrievable expandable nitinol stent for the treatment of malignant tracheobronchial stricture and/or esophagorespiratory fistula (ERF).. With fluoroscopic guidance, stents were placed in 35 symptomatic patients with malignant tracheobronchial stricture and/or ERF in most cases caused by lung or esophageal cancer. The site of stricture was most commonly at the trachea or left main bronchus. If there were complications, the stent was removed with a retrieval set. Nine patients had combined symptomatic ERF.. A total of 47 tracheobronchial stents were placed and were technically successful and well-tolerated in all patients. Improvement of dyspnea was achieved in 92% of the patients (24 of 26 patients). Associated ERF in nine patients was effectively treated with tracheobronchial stent placement with or without esophageal stent placement. Stent migration, tumor overgrowth, symptomatic sputum retention, and hemoptysis occurred in 17% (6/35), 6% (2/35), 20% (7/35), and 17% (6/35) of patients, respectively. There were no documented cases of tumor ingrowth. Stent removal was performed easily in five patients when stent migration (n = 2), severe pain (n = 1), tumor overgrowth (n = 1), or persistent gastrobronchial fistula (n = 1) developed. All patients died 2 days to 26 weeks (mean, 9.62 weeks) after stent placement because of disease progression (n = 18), pneumonia (n = 9), hemoptysis (n = 5), or unknown cause (n = 3).. Use of a covered retrievable expandable nitinol stent is a safe and effective method for relieving dyspnea. This procedure contributed to improved quality of life for patients with malignant tracheobronchial stricture and/or ERF. Stent retrievability was useful in resolving stent-related complications.
