Paul Castellanos, Manjunath Mk, Ihab Atallah
The management of tracheobronchomalacia is a very challenging problem with few treatment options. This study aims to evaluate the outcomes of a novel surgical treatment for membranous tracheobronchomalacia. A consecutive series of patients with tracheobronchomalacia were treated with two to three holmium laser scarring surgeries of the hyperdynamic tracheal and bronchial walls for the purpose of stiffening them through fibrosis. Patients filled out a Dyspnea Index questionnaire before and after treatment. Ten patients were treated for their tracheobronchomalacia with a mean age of 54 years...

The prevalence of subjects with colorectal cancer is expected to grow in the next future decades and surgery represents the most successful treatment modality for these patients. Anyway, currently elderly subjects undergo less elective surgical procedures than younger patients mainly due to the high rates of postoperative morbidity and mortality. Some authors suggest extensive surgery, including multistage procedures, as carried out in younger patients while others promote less aggressive surgery. In older patients, laparoscopic-assisted colectomy showed a number of advantages compared to conventional open surgery that include lower stress, higher rate of independency after surgery, quicker return to prior activities and a decrease in costs...

Intravascular ultrasound (IVUS) can provide valuable information regarding endoluminal morphology. We present the first description of IVUS-guided intracranial and extracranial carotid artery stent placement for arterial dissection. A 41-year-old female with a sudden-onset headache and blurred vision underwent a computed tomography (CT) angiogram imaging that revealed bilateral carotid artery dissections (BCAD) and a left vertebral artery dissection (VAD). Endovascular treatment (EVT) of a long segment right carotid artery dissection (CAD) was performed employing two Carotid WALLSTENT™ Monorails™ (8 x 36 mm, 10 x 31 mm) (Boston Scientific, Marlborough, MA)...

Full-thickness gastrointestinal defects such as perforation, anastomotic leak, and fistula are severe conditions caused by various types of pathologies. They are more likely to require intensive care and a long hospital stay and have high rates of morbidity and mortality. After intentional full-thickness opening of hollow organs for natural orifice transluminal endoscopic surgery, safe and secure closure is urgently required. The currently available advanced endoscopic closing techniques have a major role in the treatment of full-thickness gastrointestinal defects...

INTRODUCTION: Cavernous carotid aneurysms can cause significant symptomatology through mass effect and may rupture, resulting in carotid-cavernous fistula or epistaxis. Traditional treatment options included endovascular or surgical parent vessel occlusion, or embolization; in the last decade, the development of flow-diverting stents has changed the management paradigm for these lesions. AREAS COVERED: In this review, we summarize the natural history, clinical presentation, and evolution of treatment options for cavernous carotid aneurysms and discuss developments likely to influence treatment strategies in the future...

OBJECTIVE: Combined disease of the aortic arch and the proximal descending aorta remains a surgical challenge. The Thoraflex Hybrid graft (Vascutek, Inchinnan, United Kingdom) consists of a 4-branched graft with a stent graft at the distal end allowing a total aortic arch replacement, including the origins of the supra-aortic vessels combined with endoluminal treatment of the proximal descending aorta. We present the midterm results of our first 100 patients who were treated with this frozen elephant trunk prosthesis...

BACKGROUND: Neoplastic involvement of the mediastinum can contribute to both airway and esophageal pathology. That can manifest as combined esophageal and airway stenosis, or tracheobronchoesophageal fistula. Conventional palliative treatment of these problems consists of endoluminal stent insertion. The double stenting approach consists of insertion of a tracheobronchial and an esophageal stent in parallel and allows concomitant symptomatic relief of both the airway and esophageal pathology...

Conventional endovascular coiling remains the mainstay of treatment for most aneurysms; however, it may not be suitable for aneurysms with a complex geometry and there remains the risk of recanalization. Aneurysms with an unfavorable morphology are difficult to treat through both endovascular and surgical means. Progress in endovascular technology has allowed for the emergence of newer strategies to treat aneurysms with a complex geometry. Better packing density in wide-necked and large aneurysms can be achieved through the balloon remodeling technique...

BACKGROUND: A carotid web can be defined as an endoluminal shelf-like projection often noted at the origin of the internal carotid artery (ICA) just beyond the bifurcation. Diagnosis of a carotid web as an underlying cause of recurrent ischemic stroke is infrequent and easily misdiagnosed as an atheromatous plaque. Surgery has traditionally been used to resect symptomatic lesions while there is no enough evidence supporting medical therapy as the sole management. To our knowledge there is only one report about carotid artery stenting (CAS) as a definite management of carotid web and no previous reports of acute large-vessel occlusions undergoing mechanical thrombectomy in the setting of carotid web as the etiology...

BACKGROUND: Intracranial infectious aneurysms (IAs) are rare cerebrovascular lesions that represent only 1%-6% of all intracranial aneurysms. IAs are rare cerebrovascular lesions and pose a significant therapeutic challenge because of their angiographic and pathophysiologic features. We describe a patient with an intracranial IA treated by the use of reconstructive endovascular methods using a balloon-expandable covered stent and discuss the pathophysiologic characteristics of IA based on serial brain imaging findings...

BACKGROUND: Endobronchial metastases (EBM) are rarely observed, but they are caused by a number of different tumors. Bronchoscopy is the main approach for both differential diagnosis and to maintain endoluminal palliation. In this study, consecutive EBM cases that had been diagnosed and treated were evaluated in a retrospective cohort. METHODS: In total, 18 pathologically verified patients with EBM originating from extrathoracic tumors who were referred to our interventional pulmonology unit with respiratory symptoms were retrospectively evaluated...
