Salem O, El Beyrouti H, Mulorz J, Schelzig H, Ibrahim A, Oberhuber A, Dorweiler B. Predictors for reintervention and survival during long-term follow-up after thoracic endovascular aortic repair for descending thoracic aortic aneurysm. J Vasc Surg 2024:S0741-5214(24)01658-6. [PMID: 39069015 DOI: 10.1016/j.jvs.2024.07.087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2024] [Revised: 07/16/2024] [Accepted: 07/21/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND Several studies have reported short- and intermediate-term outcomes after thoracic endovascular aortic repair (TEVAR) for descending thoracic aortic aneurysm (DTAA); however, reports on long-term (10 years) outcomes are sparse. Therefore, the aim of this study was to analyze predictors impacting long-term outcome after TEVAR for DTAA. METHODS Databases from four academic institutions were reviewed and consecutive cases of TEVAR for DTAA between 1999 and 2021 were included in this retrospective multicenter study (case series). Ethical approval from the institutional review board was obtained and patient demographics and treatment data, as well as follow-up information were retrieved and analyzed. RESULTS We identified 305 patients (mean age, 72 ± 10 years) who were treated with TEVAR for degenerative DTAA with a mean aortic diameter of 64 mm. Altogether 445 endografts were implanted via femoral access (93%) with a technical success of 94%. Operative mortality, stroke rate, and rate of spinal cord ischemia were 6% (5% for intact, 12% for ruptured DTAA), 4%, and 3%, respectively. Kaplan-Meier estimates for overall survival rates were 76%, 59% and 34% at 1, 5 and 10 years and freedom from reintervention rates were 84%, 73% and 58% at 1, 5 and 10 years, respectively. In multivariate analysis, American Society of Anesthesiologists grade 3 to 5 and nonelective case were identified as predictors for death, whereas as fusiform DTAA, proximal landing zone 2, and hypertension, but not device generation, were predictive for reintervention. CONCLUSIONS This study is, to date, the largest reporting long-term (10 years) outcome on TEVAR for DTAA. We found acceptable rates for long-term survival and freedom from reintervention that were independent of endovascular device generation.

Abstract
PURPOSE The objective of this systematic review was to report the cumulative incidence of endograft migration (EM), as well as the morbidity, reintervention rates, and mortality related to EM. This study aimed to provide evidence-based data on patient-relevant sequelae of EM after thoracic endovascular aortic repair (TEVAR) performed using contemporary aortic endografts. MATERIALS AND METHODS A systematic electronic search of literature in MEDLINE (via PubMed), Web of Science, and Cochrane Central Register of Controlled Trials was performed. The pooled synthesis of outcomes was performed using the inverse variance method. RESULTS Seven prospective non-randomized and 4 retrospective studies, including a total of 1783 patients presenting 70 EMs, were considered for the quantitative analysis. The pooled rate of EM was 4% (95% CI, 2%-7%; range, 0.2%-11%; I2=82%); pooled morbidity rate was 31% (95% CI, 12%-59%; range, 0%-100%; I2=64%) and pooled reintervention rate was 32% (95% CI, 15%-56%; range, 0%-100%; I2=55%). The pooled mortality rate due to EM was 5% (95% CI, 1%-21%; range, 0%-40%; I2=24%). CONCLUSION For the first time, this meta-analysis provides pooled reference estimates of EM after TEVAR. Thus, the results hold the potential to further characterize EM after TEVAR. The clinical relevance of EM is underlined by its association with high rates of endoleak-related morbidity, reintervention, and mortality. Close standardized surveillance after TEVAR for early detection of EM and prophylaxis of its sequelae is essential.

Abstract
OBJECTIVE This article reports on a retrospective observational study designed to evaluate the incidence, etiology, and clinical implications of aortic neck dilation following thoracic endovascular aortic repair (TEVAR) for aneurysms with landing zones II and III. METHODS The study included 37 patients who underwent TEVAR and had postoperative computed tomography angiography available within 30 days and at least one computed tomography angiography at 1 year postoperatively. The primary end point was proximal aortic dilation (defined as growth ≥5 mm or ≥10% of the original diameter), and secondary end points included annual growth of the aneurysmal sac, device migration, endoleak, and reintervention with additional neck-related adverse events. The measurements taken during follow-up included the maximum diameter of the aneurysm and aortic diameter at various locations relative to the stent graft. RESULTS During follow-up, a significant increase in aortic diameter was observed at the proximal edge of TEVAR. The estimated freedom from 5 mm or 10% proximal aortic neck growth at 1, 2, and 3 years was 81%, 70%, and 65%, respectively. At the proximal edge of TEVAR the type III aortic arch was significantly associated with 5 mm growth during follow-up (P = .047) and this growth (5 mm or 10%) as well as a 10% increase at +20 mm were significantly associated with more aortic-related reinterventions. Moreover, an aortic diameter at the start <36 mm was associated with a greater increase during follow-up (area under curve in receiver operating characteristic >80%; P < .05). CONCLUSIONS The study concludes that proximal aortic dilation after TEVAR is a common and progressive phenomenon, and the management strategies for aortic neck dilation, including surveillance, secondary interventions, and open conversion, should be considered carefully to optimize patient outcomes and improve the long-term success of the procedure.

Abstract
PURPOSE The present study aims to describe a new 2D-3D fusion registration method in the case of endovascular redo aortic repair and compare the accuracy of the registration using the previously implanted devices vs. bones as landmarks. MATERIALS AND METHODS This single-center study prospectively analyzed all the patients that underwent elective endovascular re-interventions using the Redo Fusion technique between January 2016 and December 2021 at the Vascular Surgery Unit of the Fondazione Policlinico Universitario A. Gemelli (FPUG)-IRCCS in Rome, Italy. The fusion overlay was performed twice, first using bone landmarks (bone fusion) and the second using radiopaque markers of a previous endovascular device (redo fusion). The pre-operative 3D model was fused with live fluoroscopy to create a roadmap. Longitudinal distances between the inferior margin of the target vessel in live fluoroscopy and the inferior margin of the target vessel in bone fusion and redo fusion were measured. RESULTS This single-center study prospectively analyzed 20 patients. There were 15 men and five women, with a median age of 69.7 (IQR 42) years. The median distance between the inferior margin of the target vessel ostium in digital subtraction angiography and the inferior margin of the target vessel ostium in bone fusion and redo fusion was 5.35 mm and 1.35 mm, respectively (p ≤ 0.0001). CONCLUSIONS The redo fusion technique is accurate and allows the optimization of X-ray working views, supporting the endovascular navigation and vessel catheterization in case of endovascular redo aortic repair.

Abstract
Background Migration of the stent-graft post-thoracic endovascular aortic repair (TEVAR) is not uncommon; however, it is sparsely reported. The objective of this study was to assess the incidence, risk factors, and complications of stent-graft migration post-TEVAR.
Materials and Methods Thirty-one patients who underwent TEVAR were retrospectively analyzed. The demographic, anatomical, and procedure-related factors were assessed. The measurements were done along the greater curvature of aorta around two fixed anatomic landmarks, that is, left common carotid artery or neoinnominate artery (hybrid repair) proximally and celiac artery distally. Aortic elongation and migration at proximal, distal, as well as at overlapping zone were measured. More than 10 mm of migration was considered significant.
Results Significant migration was observed in six (19%) patients. No significant migration was observed in the overlapping zone. The proximal landing zone 3 (odds ratio [OR] 12.78, p 0.01) was a significant risk factor, whereas landing zone 2 was a protective factor against the migration (OR 0.08, p 0.02). The odds for migration were more in segments I/3 and II/3 compared with I/2 and II/2, respectively, as per Modified Arch Landing Areas Nomenclature. A single complication was seen in the migration group which was treated by an overlapping stent graft.
Conclusion The stent-graft migration after TEVAR is not uncommon. Type 3 proximal landing zone was a significant risk factor for migration with an increased risk toward I/3 and II/3. Proximal landing zone 2 as well as adequate overlapping distance in multiple stent grafts can prevent migration.

Abstract
Objective: The aim of this study was to report 10-year real-world single-center experience with the GORE TAG conformable thoracic aortic graft (CTAG), focusing on rupture-free survival, aortic-related reintervention, and device-related complications during midterm and long-term follow-up (FU). Methods: This retrospective study analyzes results of thoracic endovascular aortic repair (TEVAR) performed between January 2009 and December 2018. Out of 419 TEVAR procedures within this period, 194 patients (male 57.2%, 111/194), with a mean age of 65 ± 13 years, were treated with the CTAG device. Indication for TEVAR was a thoracic aortic aneurysm in 24.7% (48/194), type B aortic dissection in 32.5% (63/194), penetrating aortic ulcer 15.5% (30/194), and miscellaneous 27.3% (53/194). Emergently were operated 43.8% (85/194) patients. Median follow-up (FU) including computed tomography imaging was 43.5 months (Q1-Q3: 8.6–67.0) and was completed in 91.2% (177/194) of patients. Results: Overall survival rates were 75.8% (95% confidence interval [CI] = [0.76–0.70]) and 56.6% (95% CI = [0.57–0.50]) at 12 and 60 months, respectively. Cumulative incidence for aortic rupture was 11.9% (95% CI = [0.07–0.17]) at 60 and 90 months, respectively. Cumulative incidence for aortic-related reintervention was 27.5% (95% CI = [0.21–0.34]) at 60 and 90 months. Cumulative incidence for migration was 2.8% (95% CI = [0.004–0.05]) and 3.9% (95% CI = [0.007–0.07]) at 60 and 90 months, respectively. New endograft infections or material fatigue were not observed. Conclusions: The herein reported 10-year real-world single-center experience with the CTAG observed favorable long-term outcome. Thus, the device demonstrates appropriate persistent safety, efficacy, and clinical durability up to long-term FU in the treatment of diverse thoracic aortic pathologies.

Abstract
Endovascular repair of thoracic aortic aneurysm has become an important treatment modality in patients who are at increased risk for open surgical repair. Since the US Food and Drug Administration (FDA) approved the clinical application of this technology in the thoracic aorta in 2005, there has been a rapid growth in this treatment modality as numerous endovascular devices have been introduced in the application of thoracic aortic pathology. Although thoracic aortic aneurysm is the only FDA-approved treatment indication for endovascular repair, this technology may lead to a broader clinical applicability in other thoracic pathologies. This article reviews the current endovascular devices designed for the treatment of thoracic aortic pathology. These devices are described, and the current clinical results are discussed.

Abstract
BACKGROUND Thoracic aortic aneurysm (TAA) is an uncommon disease with an incidence of 10.4 per 100,000 inhabitants. It occurs mainly in older individuals and is evenly distributed among both sexes. There are no signs or symptoms indicative of the presence of the disease. Progressive but unpredictable enlargement of the dilated aorta is the natural course of the disease and can lead to rupture. Open chest surgical repair using prosthetic graft interposition has been a conventional treatment for TAAs. Despite improvements in surgical procedures perioperative complications remain significant. The alternative option of thoracic endovascular aneurysm repair (TEVAR) is considered a less invasive and potentially safer technique, with lower morbidity and mortality compared with conventional treatment. Evidence is needed to support the use of TEVAR for these patients, rather than open surgery. This is an update of the review first published in 2009. OBJECTIVES This review aimed to assess the efficacy of TEVAR versus conventional open surgery in patients with thoracic aortic aneurysms. SEARCH METHODS For this update the Cochrane Vascular Information Specialist searched the Specialised Register (last searched January 2016) and CENTRAL (2015, Issue 12). SELECTION CRITERIA Randomised controlled trials in which patients with TAAs were randomly assigned to TEVAR or open surgical repair. DATA COLLECTION AND ANALYSIS Two review authors independently identified and evaluated potential trials for eligibility. Excluded studies were further checked by another author. We did not perform any statistical analyses as no randomised controlled trials were identified. MAIN RESULTS We did not find any published or unpublished randomised controlled trials comparing TEVAR with conventional open surgical repair for the treatment of thoracic aortic aneurysms. AUTHORS' CONCLUSIONS Stent grafting of the thoracic aorta is technically feasible and non-randomised studies suggest reduction of early outcomes such as paraplegia, mortality and hospital stay. High quality randomised controlled trials assessing all clinically relevant outcomes including open-conversion, aneurysm exclusion, endoleaks, and late mortality are needed.

Abstract
Long-term outcomes of elective thoracic endovascular aortic repair (TEVAR) for degenerative thoracic aortic aneurysms (TAA) are not well defined. A review of the literature on the follow-up outcomes of elective TEVAR for degenerative TAA resulted in 22 relevant articles. Two- and five-year freedom from aneurysm-related death varied between 93.0% and 100.0%, and 82.4% to 92.7%, respectively. Two-year and five-year all-cause survival ranged between 68.0% and 97.2% and 47.0% to 78.0%, respectively. Follow-up ranged between 17.3 and 66.0 months. Most common endograft-related complication was endoleak, with reported rate between 1.4% and 14.8% during six months up to five years of follow-up. Endovascular reinterventions were reported in 0.0–32.3%, secondary open surgery was needed in 0.0% to 4.7% during follow-up. Aneurysm-related survival rates after elective TEVAR for degenerative TAA are acceptable. However, reported incidences of endograft-related complications vary considerably in the literature, but the majority can be managed with conservative treatment or additional endovascular procedures.

Abstract
OBJECTIVE We evaluated early and long-term results of atherosclerotic aneurysm repair with custom-made endografts. MATERIALS AND METHODS Eighty-one consecutive patients underwent thoracic endovascular aortic repair with custom-made endografts. Fenestrated grafts were used in 37 patients (45.7%) to maintain blood flow of the neck and a landing zone for as long as possible for distal arch or proximal descending aneurysms. The rates of perioperative mortality, stroke, paraplegia, and primary endoleaks were assessed to evaluate in-hospital safety. The rates of endoleak development, survival, and freedom from aortic-related death were assessed to evaluate long-term efficiency. RESULTS Twenty-four patients (29.6%) underwent urgent operations, and 38 (46.9%) underwent distal arch or proximal descending aortic aneurysm repair. There was one case (1.2%) of in-hospital mortality and no cases of stroke. Permanent spinal injury occurred in one patient (1.2%). Early and late endoleaks occurred in one and 16 patients, respectively. The actuarial survival rates were 88.9%, 64.9%, and 51.7% at 1, 5, and 10 years, respectively. The actuarial rates of freedom from endoleaks were 90.1%, 81.3%, and 68.6% at 1, 5, and 10 years, respectively. CONCLUSION Early results of custom-made endografts were excellent, and fenestrated endografts were safe for distal arch and proximal descending aortic aneurysms.

Abstract
BACKGROUND Thoracic aortic aneurysm (TAA) is an uncommon disease with an incidence of 10.4 per 100,000 inhabitants. It occurs mainly in older individuals and is evenly distributed among both sexes. There are no signs or symptoms indicative of the presence of the disease. Progressive but unpredictable enlargement of the dilated aorta is the natural course of the disease and can lead to rupture. Open chest surgical repair using prosthetic graft interposition has been a conventional treatment for TAAs. Despite improvements in surgical procedures perioperative complications remain significant. The alternative option of thoracic endovascular aneurysm repair (TEVAR) is considered a less invasive and potentially safer technique, with lower morbidity and mortality compared with conventional treatment. Evidence is needed to support the use of TEVAR for these patients, rather than open surgery. OBJECTIVES The aim of this review is to assess the efficacy of TEVAR versus conventional open surgery in patients with TAAs. SEARCH METHODS For this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched March 2013) and CENTRAL (2013, Issue 2). SELECTION CRITERIA Randomised controlled trials in which patients with TAAs were randomly assigned to TEVAR or open surgical repair. DATA COLLECTION AND ANALYSIS Two review authors independently identified and evaluated potential trials for eligibility. Excluded studies were further checked by another author. We did not perform any statistical analyses as no randomised controlled trials were identified. MAIN RESULTS We did not find any published or unpublished randomised controlled trials comparing TEVAR with conventional open surgical repair for the treatment of thoracic aortic aneurysms. AUTHORS' CONCLUSIONS Though stent grafting of the thoracic aorta is technically feasible and non-randomised studies suggest reduction of early outcomes such as paraplegia, mortality and hospital stay, high quality randomised controlled trials assessing all clinically relevant outcomes including open-conversion, aneurysm exclusion, endoleaks, and late mortality are needed.

Abstract
Stent-grafts for endovascular repair of thoracic aortic aneurysms have been commercially available for more than ten years in the West, whereas, in Japan, a manufactured stent-graft was not approved for the use until March 2008. Nevertheless, endovascular thoracic intervention began to be performed in Japan in the early 1990s, with homemade devices used in most cases. Many researchers have continued to develop their homemade devices. We have participated in joint design and assessment efforts with a stent-graft manufacturer, focusing primarily on fenestrated stent-grafts used in repairs at the distal arch, a site especially prone to aneurysm. In March 2008, TAG (W.L. Gore & Associates, Inc., Flagstaff, Arizona, USA) was approved as a stent graft for the thoracic area first in Japan, which was major turning point in treatment for thoracic aortic aneurysms. Subsequently, TALENT (Medtronic, Inc., Minneapolis, Minnesota, USA) was approved in May 2009, and TX2 (COOK MEDICAL Inc., Bloomington, Indiana, USA) in March 2011. Valiant as an improved version of TALENT was approved in November 2011, and TX2 Proform as an improved version of TX2 began to be supplied in October 2012. These stent grafts are excellent devices that showed good results in Western countries, and marked effectiveness can be expected by making the most of the characteristics of each device. A clinical trial in Japan on Najuta (tentative name) (Kawasumi Labo., Inc., Tokyo, Japan) as a line-up of fenestrated stent grafts that can be applied to distal arch aneurysms showing a high incidence, and allow maintenance of blood flow to the arch vessel was initiated. This trial was completed, and Najuta has just been approved in January of 2013 in Japan, and further development is expected. In the U.S., great efforts have recently been made to develop and manufacture excellent stent grafts for thoracic aneurysms, and rapid progress has been achieved. In particular, in the area of the aortic arch, in which we often experience aneurysmal change, but there are no commercially available devices which are urgently needed. Companies are competing keenly to develop devices. To our knowledge, more than 4 manufacturers are involved in the development of functionally new stent grafts in this area. The introduction of branched stent grafts may not be faraway.

Abstract
Research has shown that thrombus, stenosis, aneurysm, atherosclerosis and other vascular diseases are likely to occur in curved arteries such as aortic arch, coronary artery and cerebral artery. It is found that fatigue damage and failure of arteries are closely associated with the dynamic physiological environment where the arteries are situated. Based on these considerations, the behaviour of curved arteries subjected to a physiological environment is presented in this paper. The fluid-structure interaction (FSI) effect is considered. Wall stress distribution and its variation over time are investigated. Artery deformation regularity throughout the cardiac cycle has been analysed. It is believed that this study may provide insights into clinical research in the future.

Abstract
Studies showed that vascular diseases were prone to occur in curved arteries. In this paper, biomechanical behaviors of curved artery with flexible wall subjected to physiological flow were presented. Fluid-structure interaction effect was considered. The Von Mises stress variation and distribution patterns, the influence of artery curvature and flexibility on peak wall Von Mises stress, diameter change and cross sectional shape variation of the curved artery in the cardiac cycle were studied in detail. We believe that the findings may provide important implications for individualized treatment for patients with cardiovascular disease.

Abstract
Although endovascular repair of descending thoracic aneurysm has been increasingly utilized as a minimally invasive alternative to open repair, the availability of late results remains quite limited, and what exists does not yet completely reflect the rapid evolution of devices, refinement in delivery systems and maturation of both institutional and general learning curves. Durability of endografts in the thoracic aorta continues to be defined as more long-term data emerge from the major device regulatory trials. This review describes the currently available published long-term results and describes some of the anecdotally reported modes of late failure associated with the technique.

Abstract
BACKGROUND Endovascular technology has revolutionised the management of abdominal aortic aneurysmal disease but the less frequent occurrence of pathology in the thoracic aorta has meant that evidence demonstrating the primacy of endovascular treatment strategies in this portion of the vessel is less convincing. Herein we summarise the best available evidence to date. METHODS A comprehensive search of the surgical and radiological literature using the search term 'endovascular thoracic aorta' was conducted. FINDINGS AND CONCLUSIONS The vast majority of patients treated by thoracic aortic stent grafting have had their treatment outside the context of a randomised trial. While it would seem that endovascular repair is the treatment of choice for the thoracic aorta, the present evidence is based on single centre case series and is anecdotal at best.

Abstract
OBJECTIVE We sought to determine the midterm results of endovascular repair of atherosclerotic aneurysms of the thoracic descending aorta by using second-generation, commercially available stent grafts. METHODS Between 1996 and 2005, 45 patients (mean age, 68 +/- 11 years) with aneurysms of the descending thoracic aorta underwent endovascular repair. Aortic dissections, penetrating ulcers, and traumatisms were excluded. The mean follow-up was 24.7 +/- 21.6 months (maximum, 6.7 years). RESULTS No patients died, and no conversion to surgical intervention was required during the procedures. Three (6.7%) patients died during the first month, and 6 (14.7%) died later on. The main complications were strokes (13.3%), vascular access complications (8.9%), aortic complications (6.6%), paraplegia (4.4%), and sudden deaths (4.4%). Nineteen (42%) primary endoleaks were encountered: 3 required reinterventions, 15 spontaneously thrombosed, and 1 patient died. Except for 2 sudden unexplained deaths, no aortic complications were observed after 1 month. Actuarial survival estimates at 1, 3, and 5 years were 87.6% +/- 5.3%, 76.9% +/- 7.4%, and 70.6% +/- 9.2%, respectively. Actuarial freedom from death related to the treated aortic disease was 94.3% +/- 4.0%, 94.3% +/- 4.0%, and 86.4% +/- 8.4% at 1, 3, and 5 years, respectively. Aspirin status of greater than 3 (P = .005), high aortic diameter (P = .007), and long covered lengths (P = .02) were determinant for mortality. Actuarial freedom from complication was 62.6% +/- 7.7%, 58.9% +/- 8.1%, and 58.9% +/- 8.1% at 1, 3, and 5 years, respectively. The location of the aneurysm (P = .05) and a high aortic diameter (P = .04) were both determinants for endoleaks. CONCLUSIONS Stent grafting of atherosclerotic aneurysm of the thoracic descending aorta is safe and effective. Further studies are mandatory to determine the most relevant indications and the long-term efficacy of such treatment.

Abstract
OBJECTIVE To validate a means by which migration of thoracic stent grafts can be reliably detected and quantified. METHODS Patients treated for thoracic aneurysms (without dissections) with either the Cook Zenith TX1/TX2 or the Gore TAG device were retrospectively reviewed. Patients with digital imaging data at a baseline study (discharge or 1-month computed tomographic scan) and a minimum of 6 months' follow-up were evaluated on a three-dimensional workstation. Centerline of flow (CLF) calculations were used to determine length measurements to establish distances from native vascular landmarks (left common carotid artery, left common carotid artery, and celiac artery) to the proximal and distal aspects of the fixation systems of stent grafts. Patients with evidence of fixation system migration (>10 mm of movement) or increasing thoracic aortic lengths (left common carotid artery to celiac artery distance) were subjected to more detailed reviews. RESULTS Of 194 patients evaluated (133 Zenith and 61 TAG), 46 were treated for dissections and excluded. Fifty-seven patients did not have a digital baseline study and available DICOM data for follow-up imaging at 6 months or later or had died before such follow-up imaging. The remaining 91 patients underwent assessment for device migration. Analyses were conducted on 19 patients at 6 months, on 42 at 12 months, on 12 at 24 months, on 13 at 36 months, and on 5 at 48 months. CLF analysis noted more than 10 mm of caudal movement of the proximal device in 10 patients and cranial movement of the distal device in 3 patients. When this subset was further scrutinized with regard to morphologic changes remote from the prosthesis and in the context of the overall aortic repair (such as elephant trunk grafts), only four patients had movement of the proximal or distal fixation system with respect to the initially deployed location. Two-dimensional axial image analysis identified migration in only one of the four patients with CLF-detected fixation system movement. CONCLUSIONS The importance of early migration detection cannot be overstated given the potential to avert consequences as evidenced by analyses of counterpart abdominal aortic aneurysm devices. In vivo thoracic device analysis is more complex than that for devices used for infrarenal aneurysms. Distance calculations based on CLF measurements may overestimate the frequency of true migration, yet they serve as a reasonable initial screening tool. The resultant subset of patients then must undergo a more detailed evaluation of device position in the context of the aortic morphology to differentiate true migration from devices that maintain stable fixation system positions.
