RESUMO
Thoracic aortic endovascular repair (TEVAR) is increasingly preferred as a treatment of choice in thoracic aortic diseases. Intravascular foreign body is one of the TEVAR-related complications similar to the other endovascular operations. Here, to the our best knowledge for the first time in the English literature, this report presents an extremely rare complication of a broken and stuck tip part of aortic stent-graft in the intravascular space and successful removal by using the coaxial technique. Thoracic aortic endovascular repair (TEVAR) has been increasingly preferred as the treatment of choice in thoracic aortic diseases (1). Endovascular treatment has been gaining popularity compared with open surgery due to its less invasive approach and rapid application, and allows the patient to easily return to daily life (2). However, TEVAR is associated with several specific complications including paraplegia, stroke, vascular injuries and local complications. These complications depend on vascular or nonvascular comorbidities, vascular anatomy, equipment, and experience of the provider (3-6). Intravascular foreign body could be among TEVAR-related complications similar to other endovascular operations (7). Several types of equipment, including guidewire, vascular sheath, or suboptimally uncoiled stents may get stuck in the intravascular space, causing complications (8). Herein, to the best of our knowledge, we present the first report in the English literature of broken and stuck tip part of an aortic stent-graft in the intravascular space and its successful removal using the coaxial technique.

Aortic arch pseudoaneurysms are rare but quite fatal when ruptured. Owing to its less morbidity and mortality compared with the surgical approach, endovascular and hybrid treatment methods are increasingly preferred. In this report, we present a 58-year-old male patient who has a ruptured saccular aortic arch pseudoaneurysm treated by endovascular approach using parallel grafts.

Parallel endografts such as "chimney" and "periscope" are being increasingly used to maintain blood flow to visceral and supra-aortic branches in patients with different aortic disorders. We present a new technique, "iliorenal periscope graft", in a patient with abdominal aortic aneurysm undergoing endovascular aortic repair. In this case, left accessory renal artery flows were provided by an iliorenal periscope graft that extends from the left accessory renal artery to the right common iliac artery in a retrograde fashion.

BACKGROUND: This study aimed to present our experience in patients with acute traumatic thoracic aortic transection treated by endovascular stent-graft. METHODS: From October 2011 to October 2014, eleven patients were brought to our hospitals after suffering motor vehicle accident or fall from height. Computed tomography revealed acute traumatic transection of the thoracic aorta at the aortic isthmus just distal to the left subclavian artery in nine patients, at the middle or distal thoracic aorta in two, and both aortic isthmus and middle thoracic aorta in one. Endovascular technique was preferred as the treatment modality. All patients, except one, were treated within twelve hours of diagnosis. RESULTS: Deployment of stent-grafts was successful in all cases. The stent-grafts were oversized between 10% and 20%. The origin of left subclavian artery was covered with stent-graft in six patients to achieve adequate proximal landing zone. In two of them, carotico-subclavian bypass and periscope graft placement were applied to maintain subclavian artery blood flow. There were no procedure related deaths, paraplegia or ischemic complications. A patient with cardiac arrest, on whom cardiopulmonary resuscitation and transient aortic balloon occlusion within the aorta were applied in the angiography suit died at the postoperative twelve hours. Mean hospital stay after procedures was 14.8 days (range, 4-60 days). Mean follow-up time of ten patients was 16.6 months (range, 1-36 months). CONCLUSION: Our study supports that thoracic endovascular aortic stenting for acute transection is promising in terms of short- and mid-term results similar to other studies in the literature.
