“…2 a A 58- prosthesis may not completely expand in very indurated tracheal stricture since they have no self-expanding force. Self-expandable metallic stents, including Gianturco stent and Wallstent [1,2,3,4,5,6,7], have also been widely used for this condition since they were first applied to treat tracheobronchial stricture by Wallace et al in 1986 [1]. Of these stents, the Gianturco stent is the most popular since it is easy to manufacture.…”

Covered Gianturco stent for tracheal stricture: application of polychlorovinylidene and polyurethane as covering materials

et al. 2001

The aim of this study was to assess the efficacy and safety of thin membranes of polychlorovinylidene (PCV) or polyurethane (PU) as covering materials for Gianturco stents in the treatment of severe tracheal stricture caused by intraluminal tumor. Manufactured Gianturco stents covered with PCV or PU membrane were used to treat six malignant and one benign tracheal stricture. The initial results, complications, clinical follow-up, bronchoscopic findings, and three autopsy microscopic examinations were reviewed. Informed consent was obtained after the nature of the treatment had been fully explained before every procedure. The stents successfully dilated the tracheal strictures, providing immediate relief of respiratory symptoms in all patients with no major complications. During the follow-up period, the covering materials prevented tumor ingrowth until death or intraluminal granuloma formation. Autopsies proved that no histological change occurs in the tracheal mucosa in response to the presence of PCV or PU; however, ulcer formation occurred in one patient and penetration of the stent struts into the tracheal wall in two. Bloody sputum with ulcer formation, minimal granuloma formation at the distal end of the stent, and abnormal bacterial load in the sputum were long-term complications. The Gianturco stent covered with PCV or PU membrane is a useful option as a palliative treatment for malignant and an emergent salvage for benign tracheal stricture, because both materials are thinner and less voluminous than the others. However, the indications for its use are limited to patients with poor prognoses, because hemoptysis, granuloma formation, and bacterial propagation remain problematic.

“…5,6 Numerous authors 4,[7][8][9][10][11] have subsequently reported using this stent clinically, most often in the lower airway. However, metallic expandable stents are not amenable to temporary intraluminal placement since fixation of their stent hooks to the mucosal wall makes their removal difficult.…”

“…If surgical treatment for benign or malignant tumors may be difficult in a patient with tracheobronchial stenosis, stent placement can prevent respiratory failure [1][2][3][4][5][6][7][8][9]. In addition, with advances in subsequent adjuvant therapy, including radiotherapy and chemotherapy, opportunities for surgery and anesthesia are expected to increase in patients after tracheobronchial stent placement, with disappearance or reduction of primary lesions.…”

One-lung ventilation in a patient with stenting for tracheobronchial stenosis caused by esophageal cancer

We have provided general anesthesia for a 53-year-old man scheduled to undergo lymph node removal for right mediastinal lymph node metastases caused by esophageal cancer. One year prior, acute respiratory failure occurred because of stenosis of the carinal bifurcation resulting from advanced esophageal cancer with tracheal invasion. The patient underwent placement of tracheobronchial stents (Spiral Z Stent) in two locations (left main bronchus and trachea/right main bronchus), followed by radiotherapy and chemotherapy. In the present case, after an 8.5-mm-ID tracheal tube was placed under bronchoscopic guidance, a 7.0 Fr. bronchial blocker (Arndt Endobronchial Blocker; Cook, Bloomington, IN, USA) was carefully inserted into the stent in the right main bronchus. Next, 3 ml air was injected into the blocker cuff, and left-sided one-lung ventilation was performed. After surgery was completed, the bronchial blocker was removed under bronchoscopic guidance. We confirmed there was no tracheobronchial injury nor stent displacement or deformation, then removed the tracheal tube. Even in patients with tracheobronchial stent placement, one-lung ventilation can be safely and reliably performed by selecting an appropriate bronchial blocker, along with careful insertion into the stent and frequent checking of the blocker position.
