  • Abdominal aortic aneurysm (AAA) can be defined as an abnormal, progressive dilatation of the abdominal aorta, carrying a substantial risk for fatal aneurysmal rupture. Endovascular aneurysmal repair (EVAR) for AAA is a minimally invasive endovascular procedure that involves the placement of a bifurcated or tubular stent-graft over the AAA to exclude the aneurysm from arterial circulation. In contrast to open surgical repair, EVAR only requires a stab incision, shorter procedure time, and early recovery. Although EVAR seems to be an attractive solution with many advantages for AAA repair, there are detailed requirements and many important aspects should be understood before the procedure. In this comprehensive review, fundamental information regarding AAA and EVAR is presented.

  • Aortobronchial fistula may cause a massive fatal hemoptysis. Recently prosthetic aortic graft insertion or endovascular stent graft is a cause of aortobronchial fistula. We report a rare case of hemoptysis from a fistula between an aortic arch aneurysm and the left main bronchus in a patient who had undergone an endovascular stent graft in pseudoaneurysm of descending thoracic aorta one year before.

  • Vascular injuries of the extremities are associated with a high mortality rate. Conventionally, open surgery is the treatment of choice for peripheral vascular injuries. However, rapid development of devices and techniques in recent years has significantly increased the utilization and clinical application of endovascular treatment. Endovascular options for peripheral vascular injuries include stent-graft placement and embolization. The surgical approach is difficult in cases of axillo-subclavian or iliac artery injuries, and stent-graft placement is a widely accepted alternative to open surgery. Embolization can be considered for arterial injuries associated with active bleeding, pseudoaneurysms, and arteriovenous fistula and in patients in whom embolization can be safely performed without a risk of ischemic complications in the extremities. Endovascular treatment is a minimally invasive procedure and is useful as a simultaneous diagnostic and therapeutic approach, which serve as advantages of this technique that is widely utilized for vascular injuries of the extremities.

  • We report a case of concurrent saccular aneurysms caused by a penetrating atherosclerotic ulcer of the thoracic and abdominal aorta that were successfully treated by staged endovascular repair. Even though surgical open repair or endovascular repair is the treatment option, use of endovascular repair is now accepted as an alternative treatment to surgery in selected patients. To prevent contrast medium-induced nephropathy and spinal cord ischemia caused by a simultaneous endovascular procedure, a saccular aneurysm of the descending thoracic aorta was excluded by stent graft, followed by the placement of a bifurcated stent graft in the infrarenal abdominal aorta one month later.

  • Background: The endovascular approach to aortic disease treatment has been increasingly utilized in the past 2 decades. This study aimed to determine the long-term results of using the Seal thoracic stent graft. Methods: We retrospectively reviewed the outcomes of patients who underwent thoracic endovascular aortic repair or a hybrid procedure using the Seal thoracic stent graft (S&G Biotech, Seongnam, Korea) from January 2008 to July 2018 at a single institution. We investigated in-hospital mortality and the incidence of postoperative complications. We also investigated the mid-term survival rate and incidence of aorta-related complications. Results: Among 72 patients with stent grafts, 15 patients underwent the hybrid procedure and 21 underwent emergency surgery. The mean follow-up period was $37.86{\pm}30.73$ months (range, 0-124 months). Five patients (6.9%) died within 30 days. Two patients developed cerebrovascular accidents. Spinal cord injury occurred in 2 patients. Postoperative renal failure, postoperative extracorporeal membrane oxygenation support, and pneumonia were reported in 3, 1, and 6 patients, respectively. Stent-related aortic complications were observed in 5 patients (6.8%). The 1- and 5-year survival and freedom from stent-induced aortic event rates were 81.5% and 58.7%, and 97.0% and 89.1%, respectively. Conclusion: The use of the Seal thoracic stent graft yielded good mid-term results. Further studies are needed to examine the long-term outcomes of this device.

  • A 57-year-old man presented with a 2-day history of left oculomotor palsy. Digital subtraction angiography revealed a pseudoaneurysm of the left cavernous internal carotid artery (ICA) measuring $37{\times}32mm$. The pseudoaneurysm was treated with a balloon expandable graft-stent to occlude the aneurysmal neck and preserve the parent artery. A post-procedure angiogram confirmed normal patency of the ICA and complete sealing of the aneurysmal neck with no opacification of the sac. After the procedure, the oculomotor palsy improved gradually, and had completely resolved 3 months after the procedure. A graft-stent can be an effective treatment for a pseudoaneurysm of the cavernous ICA with preservation of the parent artery.

  • Endovascular treatment of the aortic aneurysm with a stent graft is rapidly evolving. We describe here a case of hybrid TEVAR (thoracic endovascular aortic repair) in which the stent grafts were placed in the aortic arch after debranching of the arch vessels. The patient had undergone ascending aorta replacement for acute type I aortic dissection 2.5 years earlier. The aneurysmal change of the distal dissection progressed with time. A provisional bypass surgery from the ascending aorta to the innominate artery and left carotid artery was performed and then stent grafts were inserted via an antegrade route that covered the whole aortic arch and proximal descending thoracic aorta.

  • Thoracic endovascular aortic repair has become a widespread alternative treatment option for thoracic aortic aneurysm. The debranching of arch vessels may be required to provide an acceptable landing zone for an endovascular stent graft. We report a case where the bypass graft used in the thoracic endovascular aortic repair procedure compressed the left internal jugular vein, causing acute thrombotic occlusion.

  • Endovascular stent grafting is regarded as a promising alternative approach to open surgical repair for treating various aortic diseases in high risk patients. We report here on a case of a 79-year-old female who underwent endovascular stent-graft insertion in the ascending aorta for treating a complicated ascending aortic rupture that occurred secondary to radiation necrosis during the treatment of recurrent breast cancer.
