Covered endovascular reconstruction of the aortic bifurcation: A systematic review aggregated data and individual participant data meta-analysis. J Vasc Surg 2024; 79:1525-1535.e9. [PMID: 38104677 DOI: 10.1016/j.jvs.2023.12.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 11/26/2023] [Accepted: 12/10/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND We investigated the early and midterm efficacy and safety of covered endovascular reconstruction of the aortic bifurcation (CERAB) in the treatment of aortoiliac disease (AID). METHODS A systematic search on PubMed, Scopus, and Web of Science for articles published by August 2023 was performed. The primary end points were primary patency and secondary patency. RESULTS Eleven retrospective case series, involving 579 patients, were incorporated in the review with 88.9% of the included lesions being categorized as Trans-Atlantic Inter-Society Consensus (TASC) C or D. The pooled primary patency estimates at 12, 24 and 36 months were 94.4% (95% confidence interval [CI], 89.4-99.7), 84.4% (95% CI, 72.3-98.5) and 83.8% (95% CI, 71.4-98.3) respectively. The mean primary patency time, representing the period during which individuals remained event-free, was 51.9 months (95% CI, 43.6-55.4). The pooled 36 months primary patency for studies with a predominantly claudicant patient population (>75% of patients) was 89.4% (95% CI, 78.5-100.0), compared with 71.5% (95% CI, 45.6-100.0) for studies with a mixed population (50% of patients). The pooled 36 months primary patency for studies with a predominantly TASC D patient population (>82% of patients) was 70.4% (95% CI, 46.4-100.0) compared with 91.0% (95% CI, 79.1-100.0) for studies with a more homogenous cohort. The pooled secondary patency estimates at 12, 24, and 36 months were 98.6% (95% CI, 96.2-100.0), 97% (95% CI, 93.1-100.0), and 97% (95% CI, 93.1-100.0), respectively. The pooled technical success, 30-day mortality and 30-day systemic complications estimates were 95.9% (95% CI, 93.7- 97.4), 1.9% (95% CI, 1.0-3.5), and 6.4% (95% CI, 4.4-9.1), respectively. The pooled intraoperative and postoperative 30-day CERAB-related complications estimates were 7.3% (95% CI, 2.0-23.0) and 4.2% (95% CI, 0.7-21.0), respectively. The pooled major amputation and target lesion reinterventions by the end of follow-up were 1.9% (95% CI, 1.0-3.4) and 13.9% (95% CI, 9.9-19.2), respectively. The pooled access site complication estimate was 11.7% (95% CI, 5.9-21.7). CONCLUSIONS Although this review has showcased the safety and feasibility of the CERAB technique in treating AID, it has also highlighted the necessity for a close and prolonged follow-up period extending beyond 1 year. Moreover, the favorable secondary patency estimates predominantly attained via endovascular reinterventions emphasize a potentially advantageous characteristic of the CERAB technique, particularly valuable when addressing late-stage AID disease or anatomically complex lesions.

[PMID: 36058456 DOI: 10.1016/j.avsg.2022.07.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 07/20/2022] [Accepted: 07/21/2022] [Indexed: 11/01/2022]
Abstract
INTRODUCTION Total occlusion of the iliac-femoral tract can cause a variety of life limiting symptoms ranging from mild claudication to chronic limb-threatening ischemia (CLTI). Efforts should be made to revascularize the symptomatic ischemic limb. Currently there are different options in the vascular surgeon's armamentarium to achieve this. The aim of the study was to verify the feasibility and outcomes of inflow hybrid revascularizations combining femoral endarterectomy and recanalization of iliac atherosclerotic occlusion. METHODS A retrospective review was conducted of all hybrid revascularizations involving femoral endarterectomy and endovascular treatment of iliac occlusion. The operations were performed in Helsinki University Hospital between 1/2013-12/2018. Firstly, information about patients' baseline characteristics, indications and details of surgery as well as technical/hemodynamic success, complications and mortality was obtained from the vascular registry and patients records. Secondarily, prospective assessment of mid-term patency was performed through follow-up (FU) in 11/2019. Immediate technical success, 30-day mortality, complications and patency were considered major outcomes. Hemodynamic improvement, amputation rate and overall mortality were also assessed. RESULTS 163 ilio-femoral occlussions were performed on 147 patients during the period studied. Six patients (3.6%) had infrarenal aortic occlusion, 86 (52.7%) had common iliac and 128 (78.5%) external iliac artery occlusion. Technical success rate was 88.3% (n=144 occlusions recanalized). Primary technical success was somewhat lower in lesions >90 mm (87.1%) compared to lesions shorter than 90 mm (95.7%; χ2 p=0.06). Iliac stent was deployed in 141 (94.6%) cases; 51 (34.3%) of which were covered stents. Significant residual stenosis remained in 1.2% of cases. Median operative time was 4 h 34 min (IQR 2h 43min), median estimated blood loss was 743ml (IQR 500ml). Five patients (3.0%) developed a deep groin infection and 12 (8.1%) suffered any major cardiovascular event or stroke perioperatively. Primary patency at 30 day, 6 months, 1 and 2 years was 98.7%, 98.1%, 96.6% and 93.7%, respectively. Hemodynamic success was documented in 107 patients (73%). By the end of the FU 7 iliofemoral tracts (11.1%) re-occluded, 2 limbs (1.2%) required amputation and 50 patients (3.0%) died. CONCLUSIONS Good immediate success rate and mid-term patency can be achieved by hybrid revascularization of ilio-femoral occlusions. Careful patient selection is mandatory since this population often suffers from universal atherosclerosis. The involvement of the aorta represents a significant determinant of worse long-term patency though it did not preclude technical success.

Abstract
Purpose Kissing stent angioplasty is an established endovascular treatment strategy for stenosis at the aortic bifurcation but not without its detractors. This study aimed to analyze the outcomes of kissing stents with regard to stent occlusion and complications in which an asymptomatic limb was treated. Methods Materials and A total of 106 patients undergoing aortic bifurcation intervention from January 2015 to November 2020 were retrospectively reviewed. Only patients with at least one common iliac artery (CIA) ostium and undergoing bilateral CIA intervention were included in the study.Results: Patients were followed up for a median period of 26 months (interquartile range, 21-51 months). The TransAtlantic InterSociety Consensus (TASC)-II classification of lesions was as follows: A, 49%; B, 41%; C, 6%; and D, 5%. The treatment indication was limited to one side in 53% of patients. Technical and procedural success rates were 99% and 90%, respectively. Ischemic events in an asymptomatic limb occurred in 6% of cases, 3% due to late stent thrombosis >30 days, and 3% due to progression of downstream infrainguinal disease. Primary and secondary patency rates at 1, 3, and 5 years were 98%, 87%, and 85%, and 99%, 94%, and 94%, respectively. Periprocedural mortality developed in two patients with no amputation. Conclusion Kissing stent deployment is a safe and effective strategy for the treatment of aortoiliac bifurcation disease. Unfavorable outcomes due to stenting in the asymptomatic iliac artery are very rare. Long-term surveillance is necessary due to the risk of late thrombosis or downstream disease progression.

Abstract
PURPOSE Despite advances in endovascular management of aorto-iliac occlusive disease (AIOD) including covered endovascular reconstruction of aortic bifurcation (CERAB) techniques, guidelines for management of symptomatic Trans-Atlantic Inter-Society Consensus (TASC II) type C/D lesions favour open surgical revascularisation. This meta-analysis investigates outcomes in patients with TASC II C/D lesions treated with open bypass procedures (OS), standard endovascular treatments (SEV) or CERAB. METHODS Multiple databases (MEDLINE, EMBASE and the Cochrane database) were searched to identify studies reporting endovascular and open treatment of extensive AIOD. Studies were independently assessed. Outcomes reported included 30-day morbidity/mortality and patency rates. RESULTS A total of 9319 patients undergoing intervention for extensive AIOD were identified from 66 studies. Median patient age was 64 years (n = 3204) for SEV, 58 years (n = 240) for CERAB and 59 years for OS (n = 5875). Pooled meta-analysis for 30-day morbidity in patients undergoing SEV, CERAB and OS was 9, 10 and 15%, respectively. Thirty-day mortality rate was 0.79, 0 and 3% in the SEV, CERAB and OS groups, respectively. In these groups, one-year primary and secondary patency was 90, 88, 96 and 96, 97, and 97% whilst three-year primary and secondary patency was 78, 82, 93 and 93, 97, 97% respectively. Five-year primary and secondary patency was 71 and 89% for SEV and 88 and 95% for OS, respectively. CERAB data were only available to 3 years. CONCLUSIONS This meta-analysis shows that thirty-day morbidity and mortality favours endovascular techniques. Primary patency remains better with OS in both early and midterms;; however, secondary patency is comparable in all groups. These findings suggest that SEV/CERAB may be considered as an alternative to OS in higher-risk patients.

Abstract
말초동맥질환은 하지혈관을 흔히 침범하는 폐쇄성 질환이다. 대동맥-장골동맥 부위에서 이를 치료하기 위한 재개통술은 전통적으로 수술적인 접근을 통한 우회술을 근간으로 하였으며, 최근에는 국소적이고 단순한 병변들을 위주로 혈관 내 접근법을 통한 치료법이 우선 권고되고 있다. 혈관 내 접근법은 그 최소침습적인 특성으로 인하여 수술의 위험성이 높은 환자에 대해서 활용하는 것이 일반적이었으나, 근래의 다양한 기법 및 기구의 발전으로 보다 다양한 질병 상태를 가진 환자에서 활용되어 수술적인 치료에 근접하는 결과가 보고되고 있다. 이 종설에서는 말초동맥 질환에 대한 진단 및 대동맥-장골동맥 부위의 혈관 내 재개통술에 활용되는 기법 및 기구들에 대해 살펴보고 그 역할에 대해 살펴보고자 한다.

Abstract
OBJECTIVE Kissing stent (KS) technique has been used as an alternative to aortic bifurcated bypass surgery (ABBS) for aortoiliac occlusive disease (AIOD). We aimed to compare the results of ABBS and KS in AIOD. METHODS Medical records of patients treated with ABBS and KS between March 2011 and December 2016 in a single center were retrospectively analyzed. The patients' characteristics and clinical outcomes were evaluated. RESULTS Patients who underwent ABBS had a more common history of smoking (P = 0.04) and lower body mass index (P = 0.02). A significant difference was observed between the two groups in terms of the TransAtlantic Inter-Society Consensus II classification (P < 0.01). A significant difference was observed between the two groups of improvement in postoperative mean ankle-brachial indexes (ABI) (ABBS: 0.57 ± 0.24 vs KS: 0.41 ± 0.18, P = 0.01). A significant difference was observed between the combined treatments of the two groups (P < 0.01). Primary patency rates of the ABBS and KS groups at 1, 2, and 3 years were 90.1% and 100%, 82.6% and 90.6%, and 82.6% and 90.6%, respectively (P = 0.637). Primary assisted patency rates of the ABBS and KS groups at 1, 2, and 3 years were 90.1% and 100%, 82.6% and 95.7%, and 82.6% and 95.7%, respectively (P = 0.110). Secondary patency rates of the ABBS and KS groups at 1, 2, and 3 years were 93.8% and 100%, 93.8% and 95.7%, and 93.8% and 95.7%, respectively (P = 0.512). CONCLUSION ABBS in AIOD remains an important revascularization option whenever endovascular treatment is not feasible.

Abstract
Background Treatment for extensive aortoiliac occlusive disease (AIOD) includes endovascular interventions, hybrid procedures and surgical reconstruction. This study evaluated the short-term outcomes of endovascular and hybrid procedures in patients with Trans-Atlantic Inter-Society Consensus II (TASC-II) D AIOD lesions. Materials and Methods From January 2013 to June 2015, 41 patients with TASC-II D AIOD lesions who underwent revascularization at our institute were retrospectively included. Nineteen underwent endovascular procedures and 22 underwent hybrid procedures with a postoperative surveillance program for at least 1 year. Patient demographics and short-term outcomes were analyzed. Results The procedural success rate in all patients was 100%. The accumulative postoperative complication rate was 20.2%, and the major complication was acute kidney injury (14.6%). The time of freedom from target lesion revascularization was 18.9 months. The primary patency rates in the endovascular group were 89.5% and 84.2% at 1 and 2 years, respectively, compared to 95.5% at 1 and 2 years in the hybrid group; however, the difference was not significant (p = 0.234). The secondary patency rates were 94.7% and 93% at 1 and 2 years, respectively, in the endovascular group, and 95.5% and 94% at 1 and 2 years, respectively, in the hybrid group; however, the differences was not significant (p = 0.916). Conclusions Our study revealed that endovascular and hybrid procedures are favorable treatment choices for patients with TASC-II D AIOD lesions. In patients with multilevel steno-occlusive lesions, hybrid procedures improved distal runoff flow and reduced the complexity of endovascular procedures.

Abstract
Open aortic repair is considered the “gold standard” treatment for aortic occlusive disease. We present the case of an 83-year-old patient with refractory hypertension caused by paravisceral aortic stenosis including both renal arteries and the superior mesenteric artery. We planned an endovascular approach and treated the patient with parallel stent grafts in the paravisceral aorta. At 1.5 years after the operation, the patient was free of hypertensive episodes. Covered endovascular repair of the paravisceral aorta may be a valuable alternative to open aortic repair in patients unfit for open surgery. More research is needed to evaluate the long-term effects of this technique.

Abstract
Complex iliac artery obstructions, particularly bilateral stenosis or total iliac artery occlusions, are usually treated with aortofemoral or aortobifemoral graft surgery. However, surgical treatment is associated with 3% mortality rate and significant morbidity such as intestinal ischemia, spinal cord injury, and ureteral damage. Percutaneous interventions of aortic bifurcation offer a promising alternative to surgery with potentially lower morbidity and mortality risk. We report a case of peripheral artery disease who had underwent right transfemoral iliac angioplasty with femoropopliteal bypass presented again with bilateral lower limb ischemia, who was successfully treated with stent implantation with the kissing balloon technique.

Abstract
OBJECTIVE/BACKGROUND Aorto-bifemoral bypass remains the gold standard for treatment of aortoiliac occlusive disease (AIOD) in patients with advanced (TASC D) lesions, but has significant associated morbidity and mortality. Treatment with a unibody stent-graft positioned at the aortic bifurcation is a potential endovascular option for the treatment of AIOD. The current study examines the safety, efficacy, and early patency rates of the Endologix AFX unibody stent-graft for treatment of AIOD. METHODS A multicenter retrospective review was conducted of patients treated exclusively for AIOD with the AFX device. Primary, assisted primary, and secondary patency rates were noted. Clinical improvement was assessed using Rutherford classification and ankle brachial index. Mean duration of follow-up was 22.2 ± 11.2 months. Ninety-one patients (56 males [62%]) were studied. RESULTS Sixty-seven patients (74%) presented with lifestyle-limiting intermittent claudication and the remaining 24 (26%) had critical limb ischemia. Technical success was 100%. Complications included groin infection (n = 4 [4%]), groin hematoma (n = 4 [4%]), common iliac rupture (n = 4 [4%]), iliac dissection (n = 4 [4%]), and thromboembolic event (n = 3 [3%]; one femoral, one internal iliac artery, and one internal iliac with bilateral popliteal/tibial thromboemboli). Thirty-day mortality was 1% (1/91) resulting from a case of extensive pelvic thromboembolism. At 1 year, 73% of patients experienced improvement in Rutherford stage of -3 or greater compared with baseline. Nine patients (10%) required 16 secondary interventions. At all time points, primary patency rates were > 90%, assisted patency rates were > 98%, and secondary patency rates were 100%. CONCLUSION This is the largest study to examine the use of the Endologix AFX unibody stent-graft for the treatment of AIOD. Use of the AFX stent-graft appears to be a safe and effective endovascular treatment for complex AIOD.

Valve-Like and Protruding Calcified Intimal Flap Complicating Common Iliac Arteries Kissing Stenting. Case Rep Vasc Med 2016; 2015:451962.

Abstract
Endovascular therapy for iliac artery chronic total occlusions is nowadays associated with low rates of procedure-related complications and improved clinical outcomes, and it is predominantly used as first-line therapy prior to aortobifemoral bypass grafting. Herein, we describe the case of a patient presenting with an ischemic left foot digit ulcer and suffering complex aortoiliac lesions, who received common iliac arteries kissing stents, illustrating at final antegrade and retrograde angiograms the early recognition of a blood flow obstructing valve-like calcified intimal flap protruding through the stent struts, which was obstructing antegrade but not retrograde unilateral iliac arterial axis blood flow. The problem was resolved by reconstructing the aortic bifurcation at a more proximal level. Completion angiogram verified normal patency of aorta and iliac vessels. Additionally, a severe left femoral bifurcation stenosis was also corrected by endarterectomy-arterioplasty with a bovine patch. Postintervention ankle brachial pressure indices were significantly improved. At the 6-month and 2-year follow-up, normal peripheral pulses were still reported without intermittent claudication suggesting the durability of the procedure. Through stent-protruding calcified intimal flap, is a very rare, but existing source of antegrade blood flow obstruction after common iliac arteries kissing stents.

Abstract
BACKGROUND To retrospectively analyze the early and the midterm results of endovascular management of aortoiliac obstructive disease with the kissing stent technique. METHODS From January 2005 to September 2012, 229 consecutive endovascular interventions for aortoiliac obstructive disease were performed; data from all the interventions were prospectively collected in a dedicated database. In 41 patients, the kissing stent technique at the level of aortic bifurcation was performed (group 1), whereas in the remaining 188 it was not (group 2). Perioperative results were compared with chi-squared test. Follow-up results were analyzed with Kaplan-Meier curves and compared with log-rank test. RESULTS Trans-Atlantic Inter-Society Consensus II C and D lesions were present in 66% of patients in group 1 and in 28.5% in group 2 (P < 0.001), whereas iliac occlusion rather than stenosis was detected in 78% of patients in group 1 and in 50% in group 2 (P = 0.001). The mean number of placed stents was 2.5 in group 1 and 1.4 in group 2 (P < 0.001). Technical success was 100% in group 1 and 98% in group 2 (P = 0.3). The rate of perioperative complications was 7.3% in group 1 and 4.2% in group 2 (P = 0.4). At 30 days, neither deaths nor major cardiovascular complications occurred. There was no thrombosis or significant restenosis at the early postoperative follow-up visit. Mean duration of follow-up was 22 months. Primary patency rates at 4 years were 70.5% (standard error [SE], 0.09) in group 1 and 75.5% (SE, 0.06) in group 2 (P = 0.7). At the same interval, assisted primary and secondary patency and survival rates were also similar; reintervention rates were 15.5% in group 1 (SE, 0.1) and 19.5% in group 2 (SE, 0.06; P = 0.6). CONCLUSIONS The kissing stent technique provided satisfactory results in patients with obstructive aortoiliac diseases, without an increase in immediate and midterm complications, representing an effective solution in complex anatomies.

Abstract
The management of aortoiliac insufficiency has been improved considerably since the introduction of balloon-expandable stents in 1991. Although numerous studies have shown the safety and efficacy of balloon-expandable iliac artery stent placement, the procedure is not without potential complication. We report here a very unusual case of iliac artery stenting being complicated by deformation and elongation of the stent following balloon rupture at initial deployment with retention of the distal balloon marker and our successful approach to subsequent management with combined acetylsalicylic acid and clopidogrel. In conclusion, this conservative approach may be an alternative treatment of a partially deployed aortoiliac stent with a retained foreign body when further intervention is considered to be of high risk.

Abstract
BACKGROUND To evaluate the long-term results in a multicentric continuous series of narrowing lesions of the aortic bifurcation treated with a kissing stent. METHODS From January, 1st 1999 to the December, 31st 2001, all of the patients (n = 80) presenting with stenosis of the aortic bifurcation (n = 15) and/or the 2 common iliac arteries (n = 65), treated with a kissing stent, in 8 teaching hospitals were collected retrospectively. The risk factors were smoking (91%), dyslipidemia (60%), arterial hypertension (42%) and diabetes (27%). In 84% of cases, the indication for treatment was claudication. The lesions were stenotic < 70% (n = 76) and/or thrombotic (n = 18). The associated lesions were external iliac stenoses (n = 21), common femoral stenoses (n = 19), femoro-popliteal stenoses (n = 42), arteriopathy in the leg (n = 35). Follow-up was clinical examination and Doppler US scan. RESULTS The success rate of the technique was 89%. There were 4 cases (5.3%) of residual stenosis and 4 cases (5.3%) of dissection. The length of the lesions treated in the aorta and the iliac arteries was respectively 17.1 ± 7 and 17.3 ± 9 mm. The stents were all placed as kissing stents, and had a mean diameter and a mean length of 13.75 mm and 56 mm in the aorta and 9 mm and 48 mm in the iliac arteries, respectively. At 5 years, 19 patients had required repeat angioplasty in the treated area, and 13 had undergone open surgery. Primary and assisted primary patency at 5 years were 64.5% and 81.8%, respectively. CONCLUSION Long-term follow-up of endovascular treatment with kissing stents for stenosis of the aortic bifurcation shows that this technique gives good results, though it does not justify doing away with classical revascularisation surgery, in a population with major cardiovascular risk factors.

Abstract
Aortobifemoral bypass is a durable arterial reconstruction with well-defined failure modes. Management of graft limb thrombosis requires restoration of inflow and correction of any causative outflow lesions. Successful, minimally invasive inflow restoration with catheter thrombectomy can become problematic if assessment of technical adequacy is deficient or reveals causal lesions within the graft body. We describe a case illustrating the potential shortfall of retrograde graft limb completion angiography in depicting neointimal flaps, the benefit of antegrade angiography in depicting these flaps, and a novel utilization of a standard endovascular method to correct flaps that involve the graft body.

Abstract
A 64-year-old female with chronic hemodialysis complained of a worsening of bilateral intermittent claudication. Computed tomographic angiography (CTA) demonstrated severe calcified bilateral aortoiliac occlusions. The kissing stent placement was therefore attempted: A 10 × 60 mm SMART stent was placed into the right aortoiliac lesion at the 1st session, and a 10 × 60 mm SMART stent was placed into the left aortoiliac lesion parallel with the previous SMART stent at the 2nd session, thus completing the "staged" kissing stent placement. CTA indicated the penetrating point in the calcified plaque clearly, and this case suggested the usefulness of CTA guided percutaneous peripheral intervention.

Abstract
PURPOSE To review the outcomes with the use of balloon-expandable covered iliac kissing stents as compared with bare metal stents in the treatment of atherosclerotic disease at the aortic bifurcation. MATERIALS AND METHODS A review of consecutive patients from a single institution with atherosclerotic occlusive disease at the aortic bifurcation treated with balloon-expandable kissing stents was performed between January 1, 2002, and September 1, 2007. Fifty-four patients were identified and divided into two groups: those with bare metal stents and those with covered stents. Technical and clinical success (Fontaine classification), complications, and patency at follow-up were documented. RESULTS Twenty-six patients (17 men, nine women; mean age, 61 years; age range, 39-79 years) received covered stents and 28 patients (15 men, 13 women; mean age, 61 years; age range, 38-82 years) received bare metal stents. Technical success was achieved in 100% of patients in both groups. Major complications occurred in three of the 26 (11%) with covered stents (P = .66) and two of the 28 patients (7%) with bare metal stents. The median follow-up was 21 months (20 months for covered stents vs 25 months for bare metal stents; range, 1-62 months). Twenty-two of the 26 patients (85%) with covered stents had sustained improvement in clinical symptoms during the follow-up period compared with 15 of the 28 patients (54%) with bare metal stents (P = .02). Primary patency rates at 1 and 2 years were 92% and 92%, respectively, for covered stents and 78% and 62% for bare metal stents (P = .023). CONCLUSIONS The use of covered balloon-expandable kissing stents for atherosclerotic aortic bifurcation occlusive disease provides superior patency at 2 years as compared with bare metal balloon-expandable stents.

Abstract
To evaluate medium-term technical and clinical success after endovascular treatment of stenosis or occlusion at the aortoiliac bifurcation with a distal aortic stent or kissing stents. Between 1995 and 2004, 25 patients were included in the study. Nine patients were treated with an aortic stent, and 16 patients were treated with kissing stents. Clinical and radiologic findings were retrospectively reviewed, and statistical analysis was performed. In all cases, the procedure was technically successful. Hemodynamic success was observed in 22 patients (88%), and clinical success was observed in 23 patients (92%). After a median follow-up of 21 months, 8 patients developed a restenosis (n = 6) or occlusion (n = 2). Two patients with restenosis were treated successfully with aortic bifurcation grafts, and 4 patients underwent endovascular reintervention. No risk factors for restenosis were identified. Primary patency was 87% after 1 year and 65% after 2 years. Secondary patency was 90% after 1 year and 72% after 2 years. At the last outpatient control, 22 patients (88%) were free of symptoms. Endovascular treatment of symptomatic aortoiliac atherosclerosis at the aortoiliac bifurcation by means of a distal aortic stent or kissing stents can be used successfully with durable improvement in the majority of patients. We recommend it as the initial treatment modality.

Abstract
PURPOSE To present the early and long-term results of aortoiliac kissing stents implantation and evaluate the risk factors affecting patency. METHODS The data were retrospectively reviewed on 68 patients (64 men; mean age 55+/-11, range 32-77) who underwent kissing stents implantation during a 12-year period. The majority of patients (64, 94%) had claudication; 4 patients had rest pain. All were smokers. There were bilateral or unilateral stenoses in 42 (62%) patients, and unilateral occlusion and contralateral stenosis in 26 (38%). Lesions were treated with simultaneous implantation of self-expanding (n=52) or balloon-expandable (n=16) stents. After the procedure, patency was determined with Doppler ultrasonography or angiography at 1, 3, 6, and 12 months and annually thereafter. Primary, assisted primary, and secondary patency rates were calculated with Kaplan-Meier analysis on an intention-to-treat basis, and risk factors affecting the patency rates were determined with the Cox regression analysis. RESULTS All procedures were technically and clinically successful. Complications occurred in 12%, but none required surgery. The follow-up period was 35+/-31 months. Primary, assisted primary, and secondary patency rates, respectively, were 76%, 90%, and 94% at 1 year; 63%, 86%, and 92% at 3 years; and 63%, 64%, and 81% at 5 years. In multivariate analysis, age <50 years and presence of iliac occlusion were identified as risk factors for reduced primary and assisted primary patency; a crossed configuration of kissing stents was identified as a risk factor for reduced primary patency. CONCLUSION Implantation of kissing stents is a safe and effective alternative in the treatment of aortoiliac obstructions. However, overall primary and assisted primary patency rates are inferior to those reported for surgery. Long-term patency comparable to surgery may be obtained in patients >50 years and in those without an iliac occlusion, particularly if a favorable stent configuration is achieved.

Abstract
We examined the proximal conformation of three commonly used self-expanding stents when the stents were deployed adjacent to one another in a tubular model, simulating a "kissing" stent technique. The stent pairs were evaluated by computed tomogrphy to determine the cross-sectional area excluded by the stents within the model. The mean areas associated with each stent pair were compared and significance evaluated by a t-test. A statistically significant difference was found when the area excluded by adjacent Wallstents was compared with both the Luminexx and SMART stents (p < 0.001 and p < 0.002, respectively). The difference in the area excluded and differences in conformation might play a role in the lower patencies that have been observed in "kissing" stent series.

Abstract
PURPOSE To determine if the position of kissing stents in the distal aorta has any influence on the patency rate. METHODS A retrospective review was conducted of 41 patients (22 men; median age 60.8 years, range 44-86) electively treated for atherosclerotic aortoiliac occlusive disease with angioplasty and kissing stents between January 1997 and January 2005. Two patient groups were defined by reviewing postinterventional anteroposterior radiograms: (1) patients in whom the proximal end of the kissing stents overlapped more than half of their angiographic width within the aorta ("crossing" group) and (2) patients in whom the proximal ends of the stents overlapped half of their width or less ("non-crossing" group). RESULTS At 2 years, the primary and assisted primary patency rates by life-table analysis were 60.8% and 69.4%, respectively, for the 35 patients included in the life-table analysis. There was no significant difference between the 16-patient "crossing" group and the 19-patient "non-crossing" group in terms of the baseline demographic, morphological, and procedural variables. The primary and assisted primary patency rates at 2 years for the "non-crossing" group were significantly higher (94.1% and 100%, respectively) compared to 33.2% and 45.3%, respectively, for the "crossing" group (p=0.01). CONCLUSIONS Failure of kissing stents in the aortic bifurcation may be significantly increased by the overlap of the free proximal stent ends in the distal aorta.

Abstract
AIMS Since the late 1980s, endovascular stents have been used in the treatment of several vascular lesions. In the last decades, stent implantation has been proposed as a reliable option for the treatment of coarctation of the aorta. In this setting, it seems to have some advantages, rendering it superior to angioplasty alone. METHODS AND RESULTS Between December 1997 and December 2004, 71 consecutive patients (44 males and 27 females) underwent cardiac catheterization for native or recurrent coarctation of the aorta. Seventy-four stents were implanted. All discharged patients were enrolled in a follow-up programme. Every patient underwent clinical evaluation, echo-colour Doppler studies, and exercise ECG at 1 and 6 months after the stent implantation. Peak systolic gradient dropped from 39.3 +/- 15.3 to 3.6 +/- 5.5 mmHg (P = 0.0041). The diameter of the coarcted segment increased from 8.3 +/- 2.9 to 16.4 +/- 3.8 mm (P = 0.037). In our series, one death occurred in a 22-year-old girl with a recurrent coarctation of the aorta, just after stent implantation. The rate of minor complications was <2%. Re-dilatation of a previously implanted stent was performed in three patients. CONCLUSION In our experience (the largest reported to the best of our knowledge), stenting of a coarctation/re-coarctation of the aorta represents a safe alternative treatment without a significant mid-long-term complication.

Abstract
PURPOSE To evaluate short and medium-term results of endovascular repair of the aortoiliac bifurcation for occlusive disease by the kissing stent technique. METHOD Twenty patients were included in this retrospective study between May 1999 and November 2002 (13 men, mean age 58 years, range 42-86). Fifteen were treated for bilateral common iliac artery stenosis (75%), four for unilateral common iliac artery occlusion with or without controlateral stenosis (20%), and one for bilateral common iliac artery occlusion (5%). Each patient had a clinical examination and dupplex-scan prior to discharge, at three months, twelve months then yearly. RESULTS All procedures were successful. Forty balloon expandable stents were deployed in the kissing position (mean length and diameter, 45 mm and 9 mm). Nine other stents were also deployed either in the abdominal aorta (one patient) either in the lower portion of the common iliac artery. Intra-operative complications were represented by one hematoma of the groin region treated surgically, one emboli of the femoral bifurcation treated by Forgarty balloon embolectomy, three dissections of the common iliac arteries treated by stenting, and one internal iliac artery occlusion not treated. Mean follow-up was 21 months (range 3-36). Three significant restenoses (>50%) were diagnosed during this period and one patient had an additional transluminal procedure. No intra-stent occlusion was found. Primary and secondary cumulative patencies at 12 and 36 months were respectively 94.7%, 84,4% and 100%, 89%. CONCLUSION We confirm the feasibility, and the reliability of endovascular aorto-iliac kissing stent reconstruction in occlusive disease for selected patients.

Abstract
PURPOSE To report our initial experience with a bifurcated endoprosthesis in the management of aortoiliac occlusive disease. METHODS From May 2001 to February 2004, 112 patients were referred to our institution for the management of aortoiliac disease. Among these, 5 (6%) patients (3 men; mean age 57.8 years) with severe ischemia owing to TASC C or D iliac occlusions were selected for endovascular treatment with a bifurcated stent-graft. An Excluder stent-graft was placed after preliminary recanalization (thrombolysis and/or balloon dilation) the day before. The patients were followed clinically and ultrasonographically every 3 months during the first year and semiannually thereafter. RESULTS Technical success was achieved in all patients. Endovascular aortoiliac bifurcation reconstruction restored iliac artery flow immediately in all cases. There were no procedure-related complications. The mean ankle-brachial index (ABI) was significantly improved, from 0.66+/-0.04 before the procedure to 0.94+/-0.06 immediately after the procedure (p<0.01). The aortoiliac reconstructions remained patent during the mean 17-month follow-up (range 3-36), and the ABIs were stable. There was no mortality or amputation required in this series. CONCLUSIONS Endovascular placement of a bifurcated stent-graft appears to be technically feasible, effective, and safe in the management of aortoiliac occlusive disease.

Abstract
OBJECTIVE We conducted a retrospective analysis of short- and mid-term results of endoluminal treatment of obstruction lesions involving the terminal aorta and the initial portions of the iliac arteries in 28 patients. PATIENTS AND METHODS Twenty-eight patients (9 women, 19 men, mean age 57.5 Years) presented 52 obstructive atheromatous lesions of the aorto-iliac bifurcation. The lesions were divided into three topographic groups (9 unilateral lesions, 19 bilateral ostial lesions, 5 widespread lesions of the terminal aorta) and identified as simple (44%) or complex (56%, more than 2 cm in length and/or calcified and/or eccentric). RESULTS Technical success was achieved in 93% of the cases with only one hematoma of the puncture site. Primary and secondary patencies were 78.9% and 93% after a mean follow-up of 50 Months (range 4-85). Clinical outcome remained good at this term for all cases of technical success but complete resolution of the symptoms was more frequent when a stent was used (84%) than for simple balloon dilatation (49%). CONCLUSION Percutaneous treatment of obstructive lesions of the aorto-iliac bifurcation may be proposed when possible as a first-line treatment.

Abstract
Endovascular intervention deploying a kissing stents (KS) technique has been used as an alternative to surgical intervention in treating symptomatic aortoiliac occlusive disease. However, the long-term results on high-risk patients are unknown. We retrospectively analyzed data on high-risk patients who underwent endovascular intervention using the KS technique at our institution. Fifty high-risk patients aged 62 +/- 6.4 years with severe aortoiliac stenosis underwent stent-supported angioplasty using the KS technique. Thirty percent of the patients had total occlusion of the distal aorta and/or the iliac arteries. Twelve patients received thrombolytics prior to stenting. The procedure was successful in all 50 patients. There was a 4% acute complication rate (distal embolization). However, there were no vascular complications, myocardial infarction, or perioperative death. Primary patency during follow-up of 20 +/- 12.3 months was 92%, while secondary patency rate was 100%. Amputation-free survival was 100%. Ninety-two percent remained free of lifestyle-limiting claudication.

Abstract
OBJECTIVES to determine medium term technical and clinical success of kissing stents for aortoiliac occlusive disease. DESIGN retrospective study. SUBJECTS twenty-five patients presenting with intermittent claudication (IC) or critical limb ischaemia (CLI) due to aortoiliac disease (41 complex stenoses, 8 occlusions). METHODS balloon- or self-expanding kissing stents, with or without predilatation depending upon the nature of the disease, were inserted via bilateral retrograde femoral artery punctures. Clinical examination, ABPI, exercise testing and duplex ultrasound were performed at 1, 3, 6, and 12 months, and then annually. RESULTS technical success was achieved in 86% segments. All patients with CLI improved and 6 of 7 ulcerated limbs showed complete healing. During follow-up, 7 patients died and two patients required major amputation at 7 and 8 months. The primary assisted patency rate was 94, 91 and 65% at 6, 12, and 24 months, respectively. CONCLUSIONS despite acceptable short-term technical and clinical success, as the medium term patency rates are clearly inferior to those of bypass surgery, the kissing stent technique should be reserved for high risk patients with a limited life expectancy.

Abstract
Intravascular stents play an increasingly important role in the treatment of iliac artery occlusive disease and their use has expanded the indications for percutaneous endoluminal therapies. The past several years have seen a sharp increase in the number of commercially available covered and uncovered stents. Knowledge of their design and mechanical properties is crucial for selecting the appropriate stent for a particular type of lesion. In this article, the indications for and results of iliac artery stent placement are reviewed and the various characteristics of the currently available stents that may influence operator choice for use in specific lesions are discussed.

Abstract
Approximately 20% of patients are unable to receive an intra-aortic balloon pump (IABP) due to aorto-iliac atherosclerotic disease. Aorto-iliac stenoses can be managed with angioplasty or stent placement; however, there are limited data about this strategy to facilitate IABP placement. Thirty-seven IABPs were placed in 35 patients. A total of 45 revascularization procedures were performed. With revascularization, the minimal lumen diameter increased from 2.78 +/- 1.46 to 6.75 +/- 2.36 mm (P < 0.0001). Limb ischemia occurred following 2/37 (5%) IABP insertions. Limb ischemia was managed with IABP removal and angioplasty. The mortality rate was 32%. Mortality was more common with chronic renal insufficiency (8/11, 73%; P = 0.0014), dialysis-dependent renal failure (3/3, 100%; P = 0.028), and presentation with acute myocardial infarction (8/15 patients, 53%; P = 0.036). Although no patients required vascular surgery for limb ischemia, one patient required surgery for bleeding. Angioplasty or stenting to facilitate IABP placement in patients with peripheral vascular disease is safe and effective.

Abstract
Atherosclerotic aorto iliac occlusive disease are not the most frequent lesions in the lower limbs. Isolated aortic iliac lesions are often associated with intermittent claudication; critical ischemia with proximal aorto iliac lesions can be due to acute occlusion or associated femoropopliteal occlusive lesions. Preoperative explorations need Duplex Scan, Arteriography and CT Scan to define extensive lesions and wall' calcifications. Endovascular procedures are, in this lesion, safe, effective and permit to delay conventional surgery. The best strategy, today, needs to known endovascular procedures and surgical procedures to obtain the most efficient anatomic result.

Abstract
BACKGROUND We report the first series of simultaneously delivered stents used to treat stenosis of the aortic bifurcation. Surgical treatment of aortoiliac occlusive disease carries up to a 3% mortality rate. Percutaneous balloon techniques to treat aortic bifurcation stenosis, although safer, are still associated with up to a 9% incidence of dissection, thrombosis, or significant residual stenosis. Kissing stent insertion should decrease the incidence of these complications. METHODS Twenty patients underwent kissing stent insertion. Suitable candidates included patients with symptoms of lower limb ischemia and significant atherosclerotic lesions in both ostial common iliac arteries (n = 15) or with extremely complex single ostial iliac stenoses (n = 5). Palmaz stents were delivered simultaneously to both limbs of the aortic bifurcation. RESULTS Kissing stent insertion was successfully performed in all 20 patients without acute complications. Mean percent stenosis decreased from 46.2%+/-24.8% to -6.8%+/-13.3% (P = .0001) in the right iliac artery, 42.3%+/-22.8% to -1.6% +/-18.1% (P = .0001) in the left iliac artery, and 19.1%+/-16.6% to 2.3%+/-16.4% (P= .0008) in the distal aorta. Intermittent claudication symptoms were improved in 18 (95%) of 19 patients with 12 (63%) of 19 patients becoming totally asymptomatic. The strongest predictor of clinical outcome after kissing stent insertion was the preprocedural extent of femoropopliteal disease: 8 (89%) of 9 patients with femoropopliteal narrowing <75% bilaterally became completely asymptomatic at follow-up compared with only 3 (30%) of 10 patients with more severe stenoses (P = .02). CONCLUSIONS We have demonstrated in 20 patients that stenoses of the aortic bifurcation can be treated effectively with kissing stents with few serious adverse events.

Abstract
OBJECTIVES In this study we report our preliminary results and intermediate-term follow-up (up to 3.5 years) of stent implantation for coarctation of the aorta (COA). BACKGROUND Balloon angioplasty has gained acceptance as a modality of treatment for COA. Some patients do not respond optimally to balloon angioplasty alone. Balloon-expandable stents have been used in pulmonary arteries and large systemic arteries such as the femoroiliac vessels, with a significant improvement in vessel patency and a reduction in the pressure gradient compared with balloon angioplasty alone. METHODS Nine patients (>10 years old) with COA in whom balloon dilation alone was thought to be ineffective underwent stent implantation. Seven patients had a previous operation or balloon dilation, or both, to relieve their coarctation but had a significant residual/recurrent gradient. RESULTS At the time of stent implantation, the systolic and mean gradients decreased from a mean (+/-SEM) of 37 +/- 7 and 14 +/- 3 mm Hg to 4 +/- 1 and 2 +/- 0.6 mm Hg, respectively (p < or = 0.002). The coarctation diameter increased from a mean of 9 +/- 1 to 15 +/- 1 mm (p < 0.002). The patients have been followed for up to 42 months (mean 18, median 13) with no complications; the stents remain in position with no fracture. One patient underwent further successful dilation 3 years after stent implantation because of an exercise-induced gradient. No other intervention has been required. The systolic gradient at latest follow-up is 7 +/- 2 mm Hg. Only two (a 44-year old with diabetes and a 50-year old with long-standing hypertension) of five patients previously requiring antihypertensive treatment still remain on medications for blood pressure control. CONCLUSIONS The use of stents in COA is a feasible alternative to surgical repair or balloon angioplasty in selected patients with an effective gradient reduction. Intermediate-term follow-up shows excellent gradient relief, with no complications in this group of patients.

Abstract
Severe aortoiliac peripheral vascular disease (PVD) is considered a contraindication for the placement of an intraaortic balloon pump (IABP) because of a high risk of limb ischemia. Recent advances in percutaneous transluminal angioplasty (PTA) and stenting have altered the treatment of iliac stenoses such that the results of PTA with stenting compare favorably with surgery. We reviewed our experience with placement of IABP between July 1994 and February 1996. Of 64 patients receiving IABP, 17 had known or suspected peripheral vascular disease. Severe iliac or distal aortic stenoses were present in 9. These 9 patients underwent PTA with or without stenting prior to 10 IABP insertions. Limb ischemia occurred in 10% of PVD patients treated with percutaneous revascularization, compared to 11% in patients without PVD. No patient had a serious vascular complication or required vascular surgery. We conclude that percutaneous revascularization in patients with severe aortoiliac PVD, for whom this IABP insertion had previously been considered contraindicated, results in a low rate of limb ischemia.

Abstract
OBJECTIVES We sought to determine the basis for restenosis within superficial femoral arteries (SFAs) and hemodialysis conduits treated with balloon-expandable stents. BACKGROUND Use of stents within coronary and peripheral vessels continues to increase exponentially. The mechanism of restenosis within stents placed at various vascular sites is not well understood. In particular, the implications of deploying a balloon-expandable stent in a compressible site are not well understood. METHODS After the serendipitous detection of stent deformation during intravascular ultrasound (IVUS) examination of a restenosed dialysis fistula, we evaluated a consecutive series of patients with stents placed in compressible vascular sites, including the SFA (six patients) and hemodialysis fistulae (five patients). Clinical, angiographic and IVUS examinations were performed to evaluate mechanisms of restenosis. RESULTS Stent compression was identified as the principal cause of restenosis in all dialysis conduits and SFAs. Stent deformity was not reliably identified by angiography; however, IVUS identified compression of two forms: eccentric deformation, implicating two-point compressive force, and complete circumferential encroachment of stent struts around the catheter, suggesting multidirectional compressive force. Despite redilation, secondary restenosis resulting from recurrent compression recurred in most sites. CONCLUSIONS Restenosis within balloon-expandable endovascular stents may occur as a result of stent compression, a phenomenon readily detected by IVUS, but often not by angiography. These findings have significant implications for the use of balloon-expandable stents within vascular sites subject to extrinsic compression, such as hemodialysis conduits, the adductor canal segment of the SFA and carotid arteries.

Abstract
The aim of this report is to review the current state of the art with respect to noncoronary vascular stenting. A review of the literature was performed, examining the historical aspects of stent design and usage, as well as the currently available designs and their respective functions. When appropriate, we note our personal experience with stent placement in each anatomic site. Currently available stents take many forms: balloon-expandable, self-expanding, and shape-memory alloy. Varied design modifications have been made to maximize the open area, to limit the surface area of the prosthesis, to increase (or decrease) flexibility, and to increase (or decrease) stent plasticity and elasticity. Modifications to minimize thrombogenicity are also underway. The clinical uses of the currently available stents in multiple anatomic locations will be discussed. Intravascular stents are an addition to the arsenal available for prolonging blood vessel patency.

Abstract
Percutaneous balloon angioplasty and endovascular stent placement are becoming common techniques intended to reduce the need for surgical bypass procedures that may be more expensive or have higher morbidity rates. Prophylactic antibiotics are not currently used before stent placement in most centers even when implanted via the femoral route. Infectious complications have been rare. In the case presented here an infected common iliac pseudoaneurysm occurred after percutaneous balloon angioplasty and stent placement. The literature is reviewed.

Abstract
We present a patient who developed endarteritis and pseudoaneurysm formation complicating iliac artery stent placement. Blood cultures grew Staphylococcus aureus. Three weeks after antibiotic treatment, the aortic bifurcation and the stents were removed, together with the left common iliac artery pseudoaneurysm. As with any other implantable device, septic complications are dreaded and should be recognized and treated early. Consideration may be given to the use of appropriate prophylactic antibiotics.

Abstract
PURPOSE We retrospectively evaluated balloon angioplasty with intraluminal stenting to define applicability, early results, cost, and length of stay. METHODS Seventy-three patients underwent 94 aorto-iliac angioplasties with intraluminal stents from October 1991 through July 1993. All had disabling claudication or rest ischemia. RESULTS Mean follow-up was 10.2 months and was 90.4% complete. Ninety percent of procedures were immediately successful. There were no deaths within 30 days of surgery. Complications occurred in 13%. The ankle:brachial indices improved in all groups. Functional class improved in all groups. In class 4, limb salvage or a benefit on level of amputation was universal. Length of stay ranged 33% to 82% less than when aorto-iliac or aortofemoral bypass were undertaken (diagnosis-related group 39.25). Hospital charges for stent procedures ranged 25% to 66% less than for aorto-iliac or aortofemoral bypass (diagnosis-related group 39.25). CONCLUSION The procedure is widely applicable, with an apparent initial advantage in mortality, morbidity, charges, and length of stay. Durability is unproven.
