Percutaneous dilatational tracheostomy (PDT) is preferred over conventional surgical tracheostomy for prolonged airway protection and mechanical ventilation. However, despite its advantages, severe PDT-related complications have been reported, including catastrophic hemorrhage from common carotid artery laceration and innominate artery pseudo-aneurysm. PDT can typically be applied to the trachea, which is the focal point for the transverse course of great vessels (e.g., the anomalous brachiocephalic trunk, which overlaps with the targeted lesion anteriorly); therefore, to improve patient outcomes, an alternative method using aortic debranching may be considered.
Background To overcome communication obstacles between medical students and trainers, we designed serial learning activities utilizing a smartphone and web-based instruction (WBI) on the Moodle platform to provide clear and retrievable trainer feedback to students on an objective structured clinical examination (OSCE) item.
Methods We evaluated students’ learning achievement and satisfaction with the new learning tool. A total of 80 fourth-year medical students participated. They installed the Moodle app (the WBI platform) on their smartphones and practiced an endotracheal suction procedure on a medical simulation mannequin while being evaluated by a trainer regarding competence in clinical skills on the smartphone app. Students’ competency was evaluated by comparing the scores between the formative assessment and the summative assessment. The degree of satisfaction and usefulness for the smartphone and WBI system were analyzed.
Results The means (standard deviations, SDs) of the formative and summative assessments were 8.80 (2.53) and 14.24 (1.97) out of a total of 17 points, respectively, reflecting a statistically significant difference (P<0.05). The degree of satisfaction and perceived usefulness of the smartphone app and WBI system were excellent, with means (SDs) of 4.60 (0.58), and 4.60 (0.65), respectively.
Conclusion We believe that the learning process using a smartphone and the Moodle platform offers good guidance for OSCE skill development because trainers’ written feedback is recorded online and is retrievable at all times, enabling students to build and maintain competency through frequent feedback review.

A 33-year-old man who had undergone bypass from the distal aortic arch to the proximal descending thoracic aorta with a Dacron graft to treat coarctation of the aorta 20 years prior presented to the emergency department with massive hemoptysis. He was diagnosed with a graft-to-bronchial fistula. After thoracic endovascular aneurysm repair through the coarctation, aortic replacement was performed 3 weeks later. Therefore, emergency-rescue thoracic endovascular aneurysm repair can be considered for preventing aortic rupture.
