Assessment of tracheal stenoses, infra-renal aortic aneurysms, and colorectal polyps

چکیده
Many conditions can lead to laryngotracheal stenosis (LTS), most frequent endotracheal intubation, followed by external trauma, or prior airway surgery. Clinical management of these stenosis requires exact information about the number, grade, and the length of the stenosis. We have developed a method for assessment of LTS. The cross-sectional profiles (based on the central path) of the upper respiratory tract (URT) were calculated for 30 patients with proven LST on fiberoptic endoscopy (FE). Locations of LTS were determined on axial S-CT slices and compared to findings of fiberoptic endoscopy (FE) by Cohen's kappa statistics. Regarding the site of LTS an excellent correlation was found between FE and S-CT (z=7.44, p<0.005). Site of LTS, length and degree could be depicted on the URT cross-sectional charts in all patients.

متن کاملFrequency of Complications Following Endovascular Repair of Abdominal Aortic Aneurysm in Tehran Sina Hospital, 2011-2019
Background and purpose: Abdominal aortic aneurysms (AAA) is a localized enlargement of infrarenal abdominal aorta. Endovascular aneurysm repair (EVAR) is a surgical method introduced for AAA repair. This study, for the first time in Iran, investigated the complications and mortality rate associated with EVAR. Materials and methods: In this cross-sectional study, medical records were reviewed...
متن کاملTreatment of co-existing thoracic and abdominal aortic aneurysms using combined endoluminal stent grafts and conventional surgery.
We report three patients with a descending thoracic aortic aneurysm (DTAA) and a separate infra-renal abdominal aortic aneurysm (AAA) who had initial endovascular repair of the DTAA followed by repair of AAA. Endovascular stent repair of DTAA avoids the significant morbidity associated with thoracotomy and open repair. Hence more patients with multilevel aortic aneurysm may be eligible for surg...
متن کاملInfra-renal abdominal aortic calcification volume does not predict small abdominal aortic aneurysm growth.
BACKGROUND Vascular calcification is a common finding in abdominal aortic aneurysms (AAA) however whether it predicts aneurysm expansion is controversial. OBJECTIVES 1) To establish a reproducible method of assessing AAA calcification using computed tomography (CT); 2) To investigate the association between AAA calcification and growth. METHOD Patients were identified from a prospectively m...
