Abstract
PURPOSE To evaluate the morbidity associated with thoracic and abdominal aortic repair using endovascular exclusion alone or combined endovascular and open repair. METHODS Between January 1998 and February 2007, 49 patients (36 men; mean age 70 years) underwent treatment for thoracic and abdominal aorta disease with descending thoracic aortic (DTA) stent-graft and abdominal aortic repair. Thirty-nine patients with coexisting thoracic and abdominal pathologies were classified with multilevel aortic disease (MLAD), whereas 10 patients presented with thoracoabdominal aneurysm. Patients were separated into 3 groups: 1: thoracic stent-grafts and open abdominal repair (n = 18), group 2: thoracic and abdominal stent-grafts (n = 21), and group 3: thoracic stent-grafts with visceral artery debranching (n = 10). Prior carotid-subclavian bypass was performed in 3 (6%) patients with a dominant left vertebral artery. RESULTS Stent-graft deployment was technically successful in all cases. Eight (16%) patients underwent emergent thoracic stent-graft placement. In 9 (18%) patients, the left subclavian artery was covered. No incidence of spinal cord ischemia was observed. The 30-day mortality was 4%, and overall mortality was 6% over a mean 33-month follow-up. The endoleak rate was 6% (1 type I, 1 type II, and 1 type III). CONCLUSION Conventional or endovascular abdominal open repair in combination with DTA stent-grafting is feasible and a safe alternative to traditional open repair. Management of MLAD did not show increased incidence of spinal cord ischemia and was associated with fewer complications and deaths than simultaneous or staged open thoracic and abdominal repairs.

Abstract
OBJECTIVE This study was conducted to determine the efficacy and safety of stent grafts in the treatment of thoracic aortic aneurysms and dissections. METHOD Our health technology assessment method combined a critical review of the literature with experts' opinions. Several databases, useful Web sites, and the gray literature were searched from January 1995 to December 2004. Some manually retrieved major articles published in 2005 were also included. The draft report was submitted to and discussed by a working group of 12 members nominated by relevant medical societies. The amended report was submitted to a multidisciplinary group of 12 peer reviewers for comment. RESULTS Endovascular stent grafting (ESG) repair for lesions of the thoracic aorta, including aneurysms, dissections, and aortic isthmus ruptures, is probably beneficial in terms of operative mortality and severe morbidity, with an incidence of paraplegia of 2.1% (range 0%-7%) for ESG vs 5% (range, 3%-15%) for surgery, provided that there is a rigorous medium-term assessment and that anatomic factors are favorable. A proximal neck length of at least 2 cm is needed to insert the stent graft. Indications for ESG in thoracic aortic aneurysm and dissection are similar to those for surgery. Endovascular stent grafting is particularly appropriate in patients with multiple traumas to the thoracic aorta in whom concomitant lesions are a contraindication to open surgery. Endovascular stent graft repair can only be done in public or private centers with expertise in both endovascular and surgical procedures and with adequate technical facilities. Patients should be informed of the advantages and drawbacks of both methods. A multidisciplinary discussion should address risks of converting to open surgery and possible need for a cardiopulmonary bypass. Patients should be monitored annually by computed tomography scan or magnetic resonance imaging and plain radiographs because long-term results are uncertain (possible stent graft deterioration, onset of aortic disease). They should be told of the need for surveillance and possible further treatment. CONCLUSIONS A prospective registry of all thoracic aorta procedures (endovascular treatment, open surgery, thoracic ESG plus extra-anatomic bypass) needs to be set up. All practitioners and stent graft manufacturers should contribute to this registry. It should include information on patient monitoring in order to (1) select patients who could be treated by ESG repair, (2) assess the feasibility of a randomized controlled study comparing ESG and surgery, (3) assess the medium-term outcome of different devices, and (4) obtain a better understanding of the health economics aspects.

Abstract
PURPOSE To evaluate our experience of thoracic endoluminal graft (ELG) repair of various thoracic aortic pathologies using a commercially available device approved by the Food and Drug Administration. Our patient population includes patients eligible for open surgical repair and those with prohibitive surgical risk. METHODS From March 1998 to March 2006, endovascular stent repair of the thoracic aorta was performed on 406 patients with 324 patients (median age 72; 200 male) receiving the Gore Excluder endograft. Patient demographics, procedural characteristics, complications, including endoleak, spinal cord ischemia, and mortality, were retrospectively reviewed during follow-up. All patients were followed with chest computer tomography at 6 months and yearly. Statistical analysis was performed utilizing the SPSS Windows 11.0 program. Logistic regression (univariate) analysis used to identify risk factors for paraplegia; analysis of variance (ANOVA) for endoleak distribution; and chi(2) used to analyze variables. Survival analysis was done using SAS version 9.1 (SAS Institute, Cary, NC). RESULTS Three hundred twenty-four patients were treated with Gore Excluder graft between March 1998 and March 2006. One hundred fifty-seven patients (48.5%) had atherosclerotic aneurysms, 82 (25.3%) had dissections type B (DTB), 34 (10.5%) had penetrating ulcers (PU), 26 (8.0%) with pseudoaneurysms (PSA), 11 (3.4%) had transections (MVAT), 9 (2.8%) aorto-bronchial fistulas (AoBF), 4 (1.2%) embolization, and 1 (0.3%) aorto-esophageal fistula (AoEF). Preoperative aneurysm sac size in TAA ranged from 5 to 12 centimeters, average size 6.3 cm. Sac shrinkage occurred in 65% (102 of 157) of patients. Average postoperative sac size of 5.4 cm in a mean follow-up of 20.4 months. One hundred cases (31.5%) were nonelective; 49 (15.1%) were ruptures. Overall complication was 22.7%, 14.2% (46) in elective cases and 8.5% (28) in nonelective cases. Paraplegia occurred in five (1.5%) patients and paresis in three (0.9%); two of the latter improved and one resolved completely prior to discharge. Incidence of paraplegia was statistically significant (P value < .05) with retroperitoneal approach, perioperative blood loss greater than 1000 cc, and aortic coverage greater than 40 cm. Early endoleaks included 18 (5.5%) type I, four (1.2%) type II, and two (0.6%) type III. Thirty-day mortality was 5.5% (18 related deaths, including three intraoperative deaths). A log rank test did not find statistical differences in actuarial survival with 30-day related mortality between TAA and other pathologies (P = .29) or between DTB and other pathologies (P = .97). Late mortality was 9.6% with 31 unrelated deaths. Follow-up ranged between 1 month and 70 months, average 17 months. CONCLUSIONS Endoluminal grafting is a feasible alternative to open surgical repair for thoracic aortic pathologies. After more than 300 cases, 30-day morbidity and mortality compares favorably with open repair. Paraplegia remains low as a complication and increases in incidence with retroperitoneal approach, increased perioperative blood loss, and increased aortic coverage.

Abstract
A 75-year-old man was referred to our hospital because of sudden thoracic pain. A saccular aneurysm of the aortic arch extending on the anterior surface of the aortic arch was found on computed tomographic arteriography. The patient was hemodynamically stable and he was programmed for a staged surgical and endovascular approach (hybrid approach). As a first stage and in order to prevent major cardiac complications due to the overstenting of the left subclavian artery (LSA) with the occlusion of the aortocoronary bypass, the patient underwent a polytetrafluoroethylene bypass graft (GORE-TEX, W.L. Gore & Associates, Flagstaff, AZ) between the LSA and the left carotid artery. Intraoperative arteriography revealed a good patency of the left carotid-subclavian bypass and of the left internal mammary bypass on the left anterior descending artery. As a second stage the endovascular procedure was accomplished 5 days later in the operating room. A Gore TAG stent graft (W.L. Gore & Associates) was deployed in the aortic arch 20 mm proximally to the aneurysmatic segment covering the ostium of the LSA. The postoperative course was uneventful and the patient was discharged on the fifth postoperative day in good general conditions. Hybrid procedures for treatment of aneurysms of the aortic arch or of the descending thoracic aorta are a promising alternative to open surgery especially in high-risk patients, with lower early morbidity and mortality rates. Long-term effectiveness remains to be fully elucidated.

Abstract
OBJECTIVES The presented study reveals the single centre experiences with the minimally invasive endovascular repair for acute traumatic thoracic aortic lesions in the care of multitrauma patients. METHODS We reviewed ten patients with acute traumatic thoracic aortic lesions treated with a thoracic aortic stent graft between April 2001 and December 2006. The prospective collected data included age, sex, injury severity score, type of endovascular graft, endovascular operation time, length of stay, length of stay in the intensive care unit, and mortality. Followup data consisted of contrast-enhanced spiral computed tomography at regular intervals. RESULTS All patients (m:f 5:5; median age, 46 years; interquartile range [IQR], 29-68.5 years) suffered severe traumatic injury, the median Injury Severity Score was 39.5 (IQR 37.3-43). All endovascular procedures were technically successful, and the median operating time for the endovascular procedure was 90 min (IQR, 65-120 min). The overall hospital mortality was 20% (n = 2), and all deaths were unrelated to the aortic rupture or stent placement. No incidence of paraplegia was present. No intervention-related mortality occurred during a median follow-up of 14.7 months (IQR, 9.7-55.8 months). CONCLUSION The endovascular approach to acute traumatic thoracic aortic lesions is feasible, safe, and effective in multitrauma patients. The low endovascular therapy-related morbidity and mortality in the postoperative period is encouraging. The results seem to be favorable to those published of open emergency repair.

Abstract
BACKGROUND In this study we evaluate published and personal experience of Endovascular Repair (EVAR) of penetrating atherosclerotic ulcers (PAU). PATIENTS AND METHOD In 12 patients (mean 74 years, 58-87 years) PAU was diagnosed with computer tomography (CT). Symptomatic ulcers were treated by vascular surgeons using stentgrafts via a femoral access route. Patients were followed up clinically and with CT for an average of 849 days (186-1968 days). RESULTS 11 patients had severe acute thoracic pain, one patient presented with hemoptysis. CT showed well outlined ulcer, intramural hematoma, and contrast enhancement of the aortic wall (n=12), pseudoaneurysm (n=11), intimal calcification adjoining the ulcer (n=10), pleural (n=9) and mediastinal fluid (n=4). Mean duration of surgery was 68min (32-120min). Primary technical success was achieved in all patients. There was no perioperative complications except one acute hemorrhage from an intercostal artery and one iliac dissection. 3 months after stentgraft application owing to a severe stenosis of the right common femoral artery, an iliofemoral bypass was performed in one patient. All patients were free of symptoms after the procedure. There was incomplete sealing of PAU in 2 of 12 patients, but no re-intervention was needed. All patients were alive during follow-up. CONCLUSION Symptomatic PAU is a potentially fatal lesion. Considering the low morbidity and mortality of EVAR, this option might be first choice.

Abstract
It still remains undetermined whether endovascular stent-graft placement (ESGP) is the optimal initial treatment for elective cases of thoracic aortic disease because of unknown long-term results. However, it is also recognized that ESGP contributes to better outcome as an initial treatment for aortic emergency, such as rupture, aortic injury, and complicated acute type B aortic dissection. Despite the fact that most patients are elderly, early mortality rates of ESGP are reportedly around 10% in cases of ruptured degenerative thoracic aortic aneurysm. Postoperative morbidity is also superior in ESGP compared with conventional open repair. Postoperative paraplegia has rarely occurred with ESGP. In cases of blunt aortic injury (BAI), other complications may also be present because of other serious injuries. ESGP has changed the surgical strategy for BAI and partially resolved some of the clinical dilemmas. Early mortality rate is almost zero when a stent graft can be placed before re-rupture. While BAI is a very good indication for ESGP, young patients need careful management and attention because of the unknown long-term outcome. In cases of complicated acute type B aortic dissection, the two main determinants of death, shock from rupture and visceral ischemia, could be managed by ESGP with or without conventional endovascular interventions. Recent reports disclosed less than 10% early mortality with ESGP for complicated acute aortic dissection. Even if the possibility of endotension remains, ESPG seems to be beneficial for these critical patients as the preferable initial treatment. The importance of close follow-up should be stressed to avoid some devastating late complications following ESGP.

Abstract
BACKGROUND Despite recent improvements in surgical technique, some patients with descending thoracic aortic pathologies are unable to undergo open surgical repair due to significant comorbidities and/or unfavorable thoracic aortic anatomy. Some of these patients might be able to tolerate a less invasive approach, such as endoluminal grafting. We reviewed our consecutive clinical experience with the Gore TAG endoprosthesis (W. L. Gore & Assoc, Flagstaff, AZ) for the endovascular exclusion of assorted descending thoracic aortic pathologies in higher surgical risk patients. METHODS After obtaining institutional review board approval, 158 high surgical risk patients underwent attempted delivery of a Gore TAG thoracic endoprosthesis between February 2000 and July 2004. Indications for study enrollment were atherosclerotic aneurysm (n = 76), aortic dissection (n = 36), penetrating aortic ulcer (n = 15), contained rupture (n = 11), pseudoaneurysm (n = 10), traumatic aortic injury (n = 5), aortobronchial fistula (n = 4), and aortic coarctation (n = 1). RESULTS The device was successfully delivered in 156 (98.7%) patients. Mean patient age was 72 +/- 12.1 years. Three (1.9%) patients developed transient paraparesis after graft deployment and 1 (0.6%) patient developed paraplegia. While postimplantation endoleaks were observed in 18 (11.5%) patients, only 12 patients required reintervention. Thirty-day mortality was 3.8% (6 of 156). Mean follow-up was 21.5 +/- 18.8 months, and the overall mortality was 17.3% (27 of 156). CONCLUSIONS Endoluminal grafting of multiple types of descending thoracic aorta pathologies with the Gore TAG thoracic endoprosthesis is feasible and safe in higher surgical risk patients. Additional studies and long-term follow-up of these patients are warranted.

Abstract
Recent US Food and Drug Administration (FDA) approval of a thoracic endograft has created explosive interest among physicians to learn to use this minimally invasive technology. The level of interest is similar to the period more than a decade ago, following FDA approval of infrarenal abdominal endografts, which initiated the "endo" revolution among vascular specialists. Many physicians view the descending thoracic aorta as a simple, straight tube and, thus, technically less challenging than endografts for infrarenal abdominal aortic aneurysm. However, the thoracic aorta presents certain unique features that make this a challenging procedure. Technical challenges posed by the thoracic aorta have resulted in a significant time-lag (since release of abdominal aortic aneurysm endografts), testing the ability of engineers and physicians to devise and complete trials successful enough for FDA approval of thoracic endografts. This article addresses the various procedural steps and tips on avoiding pitfalls.

Abstract
The purpose was to review outcome data following endovascular repair of the descending thoracic aorta from reports published between 1994 and 2004. To accomplish this task, 1,518 patients underwent endovascular repair for thoracic aortic disease; 810 thoracic aortic aneurysms, 500 type B thoracic aortic dissections, and 106 traumatic ruptures. The 30-day mortality rate was 5.5% and 6% for late postoperative deaths. The primary technical success rate was 97%, with only 15 patients requiring open conversion. Neurologic deficits occurred in 29 patients. In total, 118 endoleaks were reported; 29 were restented, and the remainder required surgical intervention. Graft infection occurred in 6 cases, and migrations were detected in 10. The conclusion reached is that endovascular repair of descending thoracic aortic disease is feasible and can be achieved with low rates of perioperative morbidity and mortality. As few long-term data exist on the durability of thoracic stent grafts, lifelong surveillance remains necessary.
