Thoracic endovascular aortic repair (TEVAR) has emerged as an effective therapy for a variety of thoracic aortic pathologies. However, various types of endoleak remain a major concern, and its treatment is often challenging. We report a case of type I endoleak occurring 19 months after zone II hybrid TEVAR. The endoleak was successfully repaired by the frozen elephant trunk technique, without removal of a previous stent graft, combined with ascending aorta and total arch replacement.

PURPOSE: Endoleak is a common complication following endovascular aortic aneurysm repairs (EVAR). The aim of this study was to discover the frequency and characteristics after EVAR with on-label use. METHODS: A retrospective review was performed on 25 patients who underwent EVAR in Inha University Hospital between December 2005 and February 2009. The data included in this study accounted for patient characteristics, anatomic features, operative technical details, and types of devices used. The results of EVAR were analyzed for clinical success, technical success and endoleak. RESULTS: Endoleaks were observed during 11 (47.8%) procedures. Type I endoleaks were observed in 2 (18.2%) cases. A total of 6 type II intraoperative endoleaks (54.5%) were observed. 3 type III endoleaks (27.3%) occurred. But all endoleaks were resolved without additional intervention CT scan after 6 months. CONCLUSION: Although the endovascular management of AAAs is less invasive than open surgery, many complications including endoleak were still the most common adverse event during the first postoperative month. However, observation may be a good treatment for minor endoleak after EVAR.

Endovascular aneurysm repair (EVAR) has been a revolutionary development in the treatment of abdominal aortic aneurysms (AAAs) since its introduction in the early 1990s. The result of the two randomized controlled trials comparing EVAR versus open repair for the treatment of AAAs has provided some insight to the advantages and limitations of EVAR technology. Endoleaks continue to be a challenge for EVAR and most endoleaks can now be successfully managed by endovascular techniques. Fenestrated and branched stent-graft technology is increasingly applied to patients with complex AAA anatomies. This paper outlines some of the concepts and discusses the controversies and challenges facing clinicians involved in EVAR today and in the future.

BACKGROUND: Conventional open repair is a suboptimal therapy for blunt traumatic aortic injury (BTAI) due to the high postoperative mortality and morbidity rates. Recent advances in the thoracic endovascular repair technique may improve outcomes so that it becomes an attractive therapeutic option. MATERIALS AND METHODS: From August 2003 to March 2012, 21 patients (mean age, 45.81 years) with BTAI were admitted to our institution. Of these, 18 cases (open repair in 11 patients and endovascular repair in 7 patients) were retrospectively reviewed and the early perioperative results of the two groups were compared. RESULTS: Although not statistically significant, there was a trend toward the reduction of mortality in the endovascular repair group (18.2% vs. 0%). There were no cases of paraplegia or endoleak. Statistically significant reductions in heparin dosage, blood loss, and transfusion amounts during the operations and in procedure duration were observed. CONCLUSION: Compared with open repair, endovascular repair can be performed with favorable mortality and morbidity rates. However, relatively younger patients who have acute aortic arch angulation and a small aortic diameter may be a therapeutic challenge. Improvements in graft design, delivery sheaths, and graft durability are the cornerstone of successful endovascular repair.

In current era, thoracic endovascular aortic repair (TEVAR) has gained popularity. But, it bears the risk of serious complications such as treatment failure from endoleak, retrograde aortic dissection caused by injury of aortic wall at landing zone, or aortic rupture resulting from stent graft infection. We report two cases of surgical repair of retrograde aortic dissection after TAVAR applied to acute Stanford type B aortic dissection or traumatic aortic disruption.

The aetiology, incidence and management of type II endoleaks in standard infrarenal endovascular aortic aneurysm repair is well described. Far less data is available for thoracic stent grafting. We present a rare and interesting case of a type II endoleak post thoracic aortic stenting and highlight the aberrant anatomy that can cause this phenomenon in such cases.

BACKGROUND AND OBJECTIVES: To evaluate the feasibility and the short- and mid-term follow-up outcomes of endovascular stent-graft implantation in patients with Stanford type B aortic dissection. SUBJECTS AND METHODS: Twenty-eight patients with Stanford type B aortic dissection were evaluated. An aortogram was performed immediately after the procedure and a follow-up computed tomography (CT) scan was performed within one week, between 3 and 6 months, and annually thereafter. Clinical status was also evaluated at the same time. RESULTS: Endovascular stent-graft implantation at the target site was successful in 27 patients (96.4%). There were primary endoleaks in 6 patients and one case of procedure failure owing to migration of the stent-graft; and no procedure-related mortality. The number of patients with early complications requiring treatment was 2 (2/27, 4%). Fourteen patients experienced postimplantation syndrome (14/27, 52%). The average follow-up period was 22.1+/-17.5 months. Complete resolution or thrombosis of the false lumen was achieved in 14 patients and partial thrombosis was achieved in 10 patients. Operative treatments were required in three patients due to a progressing dissection or new dissection. There were no deaths and no instances of aneurysm or aortic rupture during the follow-up period. CONCLUSION: Endovascular stent-graft implantation for Stanford type B aortic dissection is a feasible, safe, and effective treatment modality. All patients who underwent surgery had a persisting leak. Therefore, regular evaluation of the aortic dissection and management of endoleaks were crucial for a favorable outcome in endovascular stent-graft implantation for a Stanford type B aortic dissection.

Herein, we present a case of a successful treatment of persistent type 2 endoleaks associated with aneurysmal sac enlargement after endovascular aneurysm repair in an elderly patient. We confirmed the diagnosis by abdominal computed tomography and selective angiography revealing an 11.0-cm aneurysm sac with type 2 endoleaks. An attempt for the endovascular embolization of collateral arteries was unsuccessful due to anatomic variations and their multiple complex communications. Instead, transperitoneal sacotomy and direct suturing on the feeding target vessels was successfully performed without any endograft damage. In conclusion, sacotomy appears to be a feasible therapeutic substitute where endovascular or other techniques have a high risk of failure and lead to unsuccessful results.

Endovascular aneurysm repair (EVAR) has become prevalent and is expanding beyond conventional indications. A type I endoleak in the aortic neck is one of the main complications after EVAR, which limits long-term survival and requires immediate intervention. We experienced three cases of successful treatment of a type I endoleak after EVAR with adjunctive procedures and report them with a literature review.

Endovascular aneurysm repair (EVAR) has progressively become the preferred method for abdominal aortic aneurysm repair. Controlled studies have indicated that EVAR is related to decreased perioperative morbidity and mortality compared with open repair. However, long-term complications are more common. The most common complication following EVAR is an endoleak. Few studies on delayed type Ib endoleak with aortic rupture have been found in the literature. We report a case of a 92-year-old man with a delayed type Ib endoleak with aortic rupture that developed 7 years after EVAR. Lifelong surveillance after EVAR is mandatory.
