Editor's Choice - Covered Stents Versus Bare Metal Stents in the Treatment of Aorto-iliac Disease: A Systematic Review and Individual Participant Data Meta-analysis. Eur J Vasc Endovasc Surg 2024; 68:348-358. [PMID: 38876369 DOI: 10.1016/j.ejvs.2024.06.008] [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: 01/07/2024] [Revised: 05/12/2024] [Accepted: 06/06/2024] [Indexed: 06/16/2024]
Abstract
OBJECTIVE To assess the comparative safety and efficacy of covered stents (CS) and bare metal stents (BMS) in the endovascular treatment of aorto-iliac disease in patients with peripheral arterial disease. DATA SOURCES A systematic review was conducted adhering to the PRISMA 2020 and PRISMA for Individual Participant Data 2015 guidelines. REVIEW METHODS A search of PubMed, Scopus, and Web of Science for articles published by December 2023 was performed. The primary endpoint was primary patency. Certainty of evidence was assessed via the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. RESULTS Eleven studies, comprising 1 896 patients and 2 092 lesions, were included. Of these, nine studies reported on patients' clinical status, with 35.5% classified as Rutherford 4 - 6. Overall primary patency for CS and BMS at 48 months was 91.2% (95% confidence interval [CI] 84.1 - 99.0%) (GRADE, moderate) and 83.5% (95% CI 70.9 - 98.3%) (GRADE, low). The one stage individual participant data meta-analyses indicated a significant risk reduction for primary patency loss favouring CS (hazard ratio [HR] 0.58, 95% CI 0.35 - 0.95) (GRADE, very low). The 48 month primary patency for CS and BMS when treating TransAtlantic Inter-Society Consensus (TASC) C and D lesions was 92.4% (95% CI 84.7 - 100%) (GRADE, moderate) and 80.8% (95% CI 64.5 - 100%) (GRADE, low), with CS displaying a decreased risk of patency loss (HR 0.39, 95% CI 0.27 - 0.57) (GRADE, moderate). While statistically non-significant differences were identified between CS and BMS regarding technical success, 30 day mortality rate, intra-operative and immediate post-operative procedure related complications, and major amputation, CS displayed a decreased re-intervention risk (risk ratio 0.59, 95% CI 0.40 - 0.87) (GRADE, low). CONCLUSION This review has illustrated the improved patency of CS compared with BMS in the treatment of TASC C and D lesions. Caution is advised in interpreting overall primary patency outcomes given the substantial inclusion of TASC C and D lesions in the analysis. Ultimately, both stent types have demonstrated comparable safety profiles.

Ann Vasc Surg 2024; 106:426-437. [PMID: 38815915 DOI: 10.1016/j.avsg.2024.03.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 02/20/2024] [Accepted: 03/07/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND Aortoiliac occlusive disease (AIOD) has traditionally been treated with aortobifemoral bypass (ABF). Unibody endograft (UBE) for AIOD, however, has been increasingly utilized in selected patients. We report outcomes of patients undergoing ABF or UBE for AIOD. METHODS Patients (2016-2021) undergoing elective ABF or UBE with a unibody device for AIOD were identified at an academic institution. Chi-square and Kaplan-Meier analysis were used to evaluate outcomes by group. RESULTS One hundred thirty-one patients undergoing UBE or ABF were screened, with 82 included. Twenty-one patients underwent UBE (25.6%) and 61 (74.4%) underwent ABF. UBE patients were older (63.8 vs. 58.2 years; P = 0.01), with a higher prevalence of diabetes (52.4 vs. 19.7%; P = 0.004). Significant differences were seen between UBE and ABF including a shorter surgery length (214 vs. 360 min; P = 0.0001), less blood loss (300 vs. 620 mls; P = 0.001), larger minimum aortic diameter (14.6 vs. 12.6; P = 0.0006), larger common iliac artery (9.5 vs. 7.9; P = 0.005) and lower postoperative ankle-brachial index (0.8 vs. 0.9; P = 0.04). There were no differences in TASC C/D iliac lesions in the UBE than ABF group (66.6% vs. 63.9%; P < 0.82) or Trans-Atlantic Inter-Society Consensus classification femoropopliteal lesions. Unadjusted analysis revealed no significant differences between UBE and ABF for 30-day mortality (0 vs. 1.6%; P = 1), stroke (0 vs. 3.3%; P = 1), or major adverse cardiac events (4.8 vs. 4.9%; P = 1). There were no significant differences in mid-term surgical outcomes over a mean follow-up period of 23.7 months between UBE and ABF groups; specifically endovascular (0 vs. 8.2%; P = 0.3) or open/hybrid reintervention (9.5 vs. 14.8%; P = 0.7) with similar limb occlusion (4.8 vs. 27.8; P = 0.12). Kaplan-Meier estimated primary, primary-assisted, and secondary patency at 36 months were similar with 94%, 100%, and 94% for UBE and 86%, 95%, and 86% for ABF, respectively. Estimated survival at 36 months was 95% for UBE and 97% for ABF (P = 0.8). CONCLUSIONS Equivalent outcomes were seen between AIOD treated with UBE or ABF in similar patient populations. Mid-term outcomes such as reintervention and patency are similar for UBE and ABF. We still recommend ABF over UBE as a primary modality of treatment in surgically fit patients with greater complexity aortoiliac lesions and with smaller arterial diameters, especially women.

Role of intravascular ultrasound for the technical assessment of endovascular reconstruction of the aortic bifurcation. J Vasc Surg 2024; 80:441-450. [PMID: 38485070 DOI: 10.1016/j.jvs.2024.03.014] [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: 02/02/2024] [Revised: 02/28/2024] [Accepted: 03/05/2024] [Indexed: 04/09/2024]
Abstract
OBJECTIVE The aim of this study was to evaluate the role of intravascular ultrasound (IVUS) for the technical assessment of kissing stents (KSs) and covered endovascular reconstruction of the aortic bifurcation (CERAB) in the treatment of aortoiliac obstructive disease involving the aortic bifurcation. METHODS We conducted a single-center retrospective review of patients undergoing endovascular treatment of severe aorto-iliac obstructive disease (2019-2023). IVUS was performed in patients treated by KSs or CERAB according to preoperative indications, in cases of moderate/severe calcifications, mural thrombus, total occlusions, and lesion extension towards the proximity of renal or hypogastric arteries. Indications for IVUS-guided intraoperative revisions were residual stenosis or compression >30%, incomplete stent-to-wall apposition, or flow-limiting dissection at the landing site. Follow-up assessment was performed at 6 and 12 months, and then yearly. Thirty-day outcomes and 2-year patency rates were evaluated. Logistic regression was used to identify factors associated with significant technical defects detected by IVUS needing intraoperative revision. RESULTS IVUS was used for the technical assessment of 102 patients treated by KSs (n = 57; 56%) or CERAB (n = 45; 44%) presenting with severe intermittent claudication (39%), rest pain (39%), or ischemic tissue loss (25%). Twenty-nine significant technical defects were identified by IVUS in 25 patients (25%) who then had successful intraoperative correction by additional ballooning (n = 23; 80%) or stenting (n = 6; 20%). Patients with a severely calcified chronic total occlusion (odds ratio, 1.85; 95% confidence interval, 1.01-5.27; P = .044) or severely calcified narrow aortic bifurcation with <12 mm diameter (odds ratio, 2.34; 95% confidence interval, 1.10-8.64; P = .032) were at increased risk for IVUS-guided intraoperative revision. There were no postoperative deaths and no major adverse events. Two-year primary patency was 100%. CONCLUSIONS IVUS was used for the technical assessment of KSs/CERAB in a selected cohort of patients with severe aorto-iliac obstructive disease. This allowed the identification and intraoperative correction of a significant technical defect not detected by completion angiogram in one-quarter of patients, achieving optimal 2-year results. IVUS assessment of KSs/CERAB may be considered especially in patients with a calcified total occlusion or narrow aortic bifurcation.

Abstract
BACKGROUND Endovascular treatment is nowadays accepted as first-line treatment for most patients with aorto-iliac obstructive disease (AIOD), including those with Trans-Atlantic Inter-Society Consensus II (TASC-II) lesion types C and D. Aim of the study was to evaluate the role of Viabahn VBX (W. L. Gore and Associates, Flagstaff, AZ, USA), in patients with chronic occlusive aorto-iliac disease (ChO). METHODS A retrospective review of patients undergone elective endovascular repair with VBX (W. L. Gore and Associates) for ChO at five referral vascular institutions in Italy from 2018 to 2022 was conducted. Primary endpoints were technical success and the incidence of any early and midterm procedure-related reintervention. Secondary endpoints were clinical success, primary and secondary patency. RESULTS Among 89 included patients, technical success was obtained in 87 patients (97.8%). Postoperative complication requiring early surgical reintervention was necessary in 5 (6%), all but one for arterial bleeding. Clinical improvement of at least 3 classes was observed in 49 (55%). After a mean follow-up of 24.1 months ±14.1, primary patency and freedom from any procedure-related reintervention at 12, 24 and 36 months was 83.0% and 94.8%, 80.0% and 91.5%, 77.9% and 89.3%, respectively. Secondary patency was 100%. TASC-II D lesion (OR=3.67, 95% CI: 1.1289-11.9823, P=0.03) and Grade III iliac calcification (OR=3.41, 95% CI: 1.0944-10.6428, P=0.03) were identified as independent predictors for procedure-related reintervention. CONCLUSIONS Use of VBX (W. L. Gore and Associates) in ChO was safe and effective with low rate of stenosis/occlusion in the early and mid-term follow-up. TASC-II D and Grade III calcifications resulted as independent predictors for procedure-related reintervention.

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.

Abstract
PURPOSE This study aimed to assess the efficacy and safety outcome of covered stents (CSs), as compared with bare-metal stents (BMSs), for the treatment of patients with aortoiliac occlusive disease (AIOD). MATERIALS AND METHODS A systematic literature search was conducted in PubMed, Embase, and Cochrane Library up to August 2023 to identify all studies comparing efficacy and safety outcomes of CSs versus BMSs for treating AIOD. Our outcome was primary patency, secondary patency, technical success, ankle-brachial index (ABI) variation, target lesion revascularization (TLR), limb salvage, complications, and long-term survival. Dichotomous outcomes were pooled as relative risks (RR) or hazard ratio with the 95% confidence interval (CI). Continuous outcomes were pooled as weighted mean differences and 95% CI. Model selection was based on the heterogeneity of the included studies. RESULTS There were 10 studies (2 randomized controlled trials, 8 retrospective cohort studies), comprising 1676 sample size. Compared with BMSs, CSs use was associated with better primary patency of patients with a Trans-Atlantic Inter-Society Consensus II (TASC) D lesion (RR, 1.15, 95% CI, 1.04 to 1.27, p=0.007), TLR (RR, 0.39, 95% CI, 0.27 to 0.56, p<0.001), technical success (RR, 1.01, 95% CI, 1.00 to 1.02, p=0.010), and long-term survival (RR, 1.06, 95% CI, 1.01 to 1.11, p=0.020). There is no difference between CSs and BMSs regarding primary patency of all patients, secondary patency, variation in ABI, limb salvage, and complications. CONCLUSIONS Compared with BMSs, CSs used in AIOD was associated with more favorable primary patency in patients with TASC D lesions, TLR, technical success rates, and patient long-term survival. These results provide evidence of the advantages of using CSs for AIOD treatment. Future studies focusing on long-term variations in ABI, primary patency of different degrees of calcification, vascular segments, and TASC classification are warranted. CLINICAL IMPACT Although several studies evaluated the clinical efficacy of CS in the context of AIOD treatment, the significance and consistency of these findings were not determined to date. We found that CS was used in AIOD associated with better technical success rate, long-term patient survival, lower target lesion revascularization, and higher primary patency of patients with a Trans-Atlantic Inter-Society Consensus II D lesion when compared with BMSs. Our study provides evidence supporting the superiority of CSs over BMSs in the treatment of AIOD, and furnishing clinicians with guidance for treatment decisions.

Abstract
OBJECTIVE We retrospectively compared the clinical outcomes of self-expanding covered stents (CSs) and bare metal stents (BMSs) in the treatment of aortoiliac occlusive disease (AIOD) at a single center between 2016 and 2022. METHODS All patients with AIOD receiving endovascular therapy at a single center from January 2016 to October 2022 were continuously analyzed, including patients with lesions of all classes according to the Trans-Atlantic Inter-Society Consensus II (TASC-II). Relevant clinical and baseline data were collected, and propensity score matching was performed to compare CSs and BMSs in terms of baseline characteristics, surgical factors, 30-day outcomes, 5-year primary patency, and limb salvage. The follow-up results were analyzed by Kaplan-Meier curves. Cox proportional hazard models were used to identify predictors of primary patency. RESULTS A total of 209 patients with AIOD were enrolled in the study, including 135 patients (64.6%) in the CS group and 74 patients (35.4%) in the BMS group. Surgical success rates (100% vs 100%; P = 1.00), early (<30-day) mortality rates (0% vs 0%; P = 1.00), cumulative surgical complication rate (12.0% vs 8.0%; P = .891), 5-year primary patency rate (83.4% vs 86.9%; P = .330), secondary patency rate (96% vs 100%; P = .570), and limb salvage rate (100% vs 100%; P = 1.00) did not exhibit significant differences between the two groups. Patients in the CS group had a lower preoperative ankle-brachial index (0.48 ± 0.26 vs 0.52 ± 0.19; P = .032), more cases of complex AIOD (especially TASC D) (47.4% vs 9.5%; P < .001), more chronic total occlusive lesions (77.0% vs 31.1%; P < .001), and more severe calcification (20.7% vs 14.9%; P < .036). After propensity score matching, 50 patients (25 with CS and 25 with BMS) were selected. The results showed that only severe calcification (32.0% vs 8.0%; P = .034) and ankle-brachial index increase (0.45 ± 0.15 vs 0.41 ± 0.22; P = .038) were significantly different between the groups. In terms of surgical factors, patients in the CS group had more use of bilateral femoral or combined brachial artery percutaneous access (60.0% vs 12.0%; P < .001), more number of stents used (2.3 ± 1.2 vs 1.3 ± 0.7; P < .001), longer mean stent length (9.3 ± 3.3 vs 5.8 ± 2.6 cm; P < .001), and more catheter-directed thrombolysis treatment (32.0% vs 4.0%; P = .009). Multivariate Cox survival analysis showed that severe calcification (hazard ratio, 1.32; 95% confidence interval, 1.04-1.85; P = .048) was the only independent predictor of the primary patency rate. CONCLUSIONS All patients with AIOD who underwent endovascular therapy were included and achieved good outcomes with both CSs and BMSs. The influence of confounding factors in the two groups was minimized by propensity score matching, and the 5-year patency rates were generally similar in the unmatched and matched cohorts. Postoperative hemodynamic improvement was more obvious in patients in the CS group. For more complex lesions, CS is recommended to be preferred. Especially for severe calcification lesions, which is the only independent predictor of primary patency, CS showed obvious advantages. Further studies with more samples are needed to investigate the role of stent types in AIOD treatment.

Abstract
Introduction Pseudoaneurysms of the subclavian artery are a rare complication. Surgical treatment is necessary to prevent potentially lethal complications. This needs adequate planning in cases that require vertebral artery revascularisation. Report A 56 year old man with multiple systemic comorbidities underwent endovascular treatment using a balloon expandable bare metal stent for symptomatic subclavian Steal syndrome. During follow up, computed tomography angiography (CTA) revealed a pseudoaneurysm in the proximal segment of the left subclavian artery. The patient had criteria warranting left vertebral artery revascularisation. The patient underwent scheduled hybrid surgical treatment involving transposition of the vertebral artery to the common carotid artery, endarterectomy of the internal carotid artery, and endovascular therapy for pseudoaneurysm exclusion; all were performed on the left side. The post-operative period was without incident. After 12 months the patient remains asymptomatic, with adequate exclusion of the pseudoaneurysm, and patency of the procedures. Discussion Hybrid surgery could offer a secure, feasible, and less invasive option for treating subclavian artery pseudoaneurysms that require vertebral artery revascularisation.

Abstract
We describe the feasibility of covered endovascular reconstruction of the aortic bifurcation (CERAB) through a single femoral access and a steerable sheath. We present the technique, which we used for a patient with severe aortoiliac calcification and bilateral involvement of the common femoral artery. The patient underwent endarterectomy of the left common femoral artery plus CERAB with an aortic stent graft and bilateral covered stents for the common iliac artery with kissing dilatation with a steerable sheath using only left femoral access. CERAB can be performed using unilateral access with the aid of a steerable sheath, reducing the potential for access site complications.

Abstract
PURPOSE Covered stents and bare metal stents (BMS) have been regarded as viable treatment options for aortoiliac arterial diseases. We performed this systematic review and meta-analysis to compare the efficacy of covered stents with BMS for aortoiliac arterial diseases. MATERIALS AND METHODS The Cochrane Library, Embase, and Medline databases were searched by 2 authors (C.Z. and Z.W.) to retrieve all studies comparing the outcomes of covered stents vs BMS for aortoiliac arterial diseases. The Cochrane tool and the Newcastle-Ottawa scale were used to assess the risk of bias in randomized controlled trials and observational studies, respectively. The outcomes at the same stage reported in at least 2 studies were pooled together. The fixed effects model combined the data when I2<50%, otherwise the random effects model was applied. The results for dichotomous variables were presented as odds ratio (OR) or risk difference and 95% confidence interval (CI); continuous variables were reported as mean difference and 95% CI. RESULTS Herein, 10 studies with a total of 1695 limbs were included. The covered stents significantly increased the freedom from target lesion revascularization (OR 2.85, 95% CI: 1.28-6.33, p=0.010) compared to the BMS during a 24-month follow-up. However, no statistically significant difference was found in the technical success, primary patency, secondary patency, major adverse events (MAEs), ankle-brachial index (ABI) improvement, limb salvage, and survival between the two groups. CONCLUSION Compared to BMS, covered stents appear to have similar technical success, primary patency, secondary patency, MAEs, ABI improvement, limb salvage, and survival but may have advantages in reducing target lesion revascularization. More well-designed, prospective studies are warranted to determine such findings. CLINICAL IMPACT Covered stents may increase freedom from target lesion revascularization (TLR) compared to bare metal stents (BMS) in the treatment of aortoiliac arterial diseases. However, technical success, primary patency, secondary patency, major adverse events (MAEs), ABI improvement, limb salvage, and survival were similar. The aforementioned results are still not sufficient to draw a solid conclusion about the selection of stents for aortoiliac arterial diseases. More well-designed, prospective studies are warranted to determine such findings.

Ann Vasc Surg 2023:S0890-5096(23)00111-5. [PMID: 36870565 DOI: 10.1016/j.avsg.2023.02.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 01/30/2023] [Accepted: 02/05/2023] [Indexed: 03/06/2023]
Abstract
BACKGROUND We sought to investigate the midterm results of kissing self-expanding covered stents (SECSs) for the reconstruction of aortic bifurcation in complex aortoiliac occlusive disease. METHODS Data of consecutive patients who had undergone endovascular treatment for aortoiliac occlusive disease were screened. Only patients with TransAtlantic Inter-Society Consensus (TASC) class C and D lesions treated by bilateral iliac kissing stents (KSs) were included. Midterm primary patency, risk factors, and limb salvage rates were analyzed. Follow-up results were analyzed using the Kaplan-Meier curves. Cox proportional hazards models were used to identify the predictors of primary patency. RESULTS A total of 48 patients (95.8% men; mean age, 65.3 ± 10.2 years) were treated with kissing SECSs. Of them, 17 patients had TASC-II class C lesions and 31 had class D lesions. There were 38 total occlusive lesions, with a mean occlusive lesion length of 108.2 ± 57.3 mm. The overall mean lesion length was 140.3 ± 60.5 mm, and the mean length of implanted stents in the aortoiliac arteries was 141.9 ± 59.9 mm. The mean diameter of the deployed SECSs was 7.8 ± 0.5 mm. The mean follow-up time was 36.5 ± 15.8 months, and the follow-up rate was 95.8%. At 36 months, the overall primary patency, assisted primary patency, secondary patency, and limb salvage rates were 92.2%, 95.7%, 97.8%, and 100%, respectively. Univariate Cox regression analysis revealed that stent diameter ≤7 mm (hazard ratio [HR]: 9.53; 95% confidence interval [CI] 1.56-57.94, P = 0.014) and severe calcification (HR: 12.66; 95% CI 2.04-78.45, P = 0.006) were significantly associated with restenosis. Multivariate analysis showed severe calcification to be the only significant determinant of restenosis (HR: 12.66; 95% CI 2.04-78.45, P = 0.006). CONCLUSIONS Kissing SECSs provide good midterm results for the treatment of aortoiliac occlusive disease. A stent diameter >7 mm is a potent protective factor against restenosis. Because severe calcification appears to be the only significant determinant of restenosis, patients with severe calcification require close follow-up.

Abstract
In the present report, we have described the use of intravascular lithotripsy angioplasty for heavily calcified occlusions of the infrarenal aorta and its bifurcation in two patients. In the first patient, two lithotripsy balloons in kissing conformation were simultaneously used to allow for dilatation of the distal aorta and its bifurcation with preservation of accessory renal artery patency, followed by stenting of the iliac arteries. For the second patient, the infrarenal aorta occlusion was first treated with a single lithotripsy balloon, followed by covered stenting. Intravascular lithotripsy could represent a valid endovascular adjunct to optimize outcomes in the treatment of coral reef aortas and aortic bifurcation occlusion.

Abstract
PURPOSE To describe the early results and mid-term patency rates of external iliac artery (EIA) stenting using self-expanding covered stents. METHODS We conducted a multicenter retrospective study (2015-2021), including patients receiving primary endovascular treatment of external iliac artery occlusive disease with self-expanding covered stents. All patients were treated with the Viabahn (W.L Gore & Associates, Inc., Flagstaff, AZ-USA) stent. Patency and limb salvage rates were estimated with Kaplan-Meier curves. RESULTS Ninety-three patients (mean age, 69 ± 9 years; 81% males) were treated for disabling claudication in 44%, rest pain in 28%, and tissue loss in 28%. TASC C/D lesions were present in 72% and iliac complete occlusion in 30%. Mean lesion length was 6.9 ± 2.4 cm; 30% had moderate/severe EIA calcifications; and the mean iliac tortuosity index was 1.17 ± 0.13. Technical success was 100%. There was one perioperative death (1.4%) and procedural complication rate was 6.5%. At 42 months (mean, 25 months), primary patency was 89.8% (95%CI 83-98); the presence of EIA tortuosity (tortuosity index > 1.25, 87.7 ± 11% vs 89.9 ± 8%; P = .6) or severe calcifications (87.6 ± 9% vs 96.0 ± 8%; P = .400) had no significant impact. After univariate analysis, the use of a stent with diameter < 8 mm (HR 8.5, 95%CI 3.24-14.22; P < .001) was negatively associated with primary patency. CONCLUSIONS The use of self-expanding covered stents provided excellent early and mid-term results in the treatment of obstructive disease of the EIA, also in cases of high EIA tortuosity and high grade of calcifications. The use of a < 8 mm-diameter stent was associated with a reduced primary patency.

Abstract
Objectives: To analyze outcomes following endovascular treatment of total occlusion of the infrarenal aorta and aorto–iliac bifurcation in a multicenter Italian registry. Methods: It is a multicenter, retrospective, observational cohort study. From January 2015 to December 2018, 1306 endovascular interventions for aorto–iliac occlusive disease were recorded in the vascular registry. For this analysis, only patients treated for total occlusion of the infrarenal aorta and aorto–iliac bifurcation were included. Early (<30 days) primary outcomes of interest were technical success and mortality. Late major outcomes were primary and secondary patency and freedom from conversion to open aortic surgery. Results: A total of 54 (4.1%) patients met the inclusion criteria. Total percutaneous revascularization was possible in 41 (75.9%) patients and hybrid (endo plus open) intervention in 13 (24.1%) patients. The kissing-stent-graft technique was used in 45 (83.3%) cases, covered endovascular reconstruction of the aortic bifurcation (CERAB) in 5 (9.2%), and a unibody endograft deployed in 4 (7.4%). Technical success was 98.1% (n = 53). There were no episodes of intraoperative or perioperative vessel rupture. Conversion to open surgery was not necessary, and there were no in-hospital deaths. The median patient follow-up time was 16 months (interquartrile range [IQR], 6-27). The estimated primary patency rate was 95.8% ± 0.03 (95% confidence interval [CI]: 85.5-98.9) at 1 year, 91.4% ± 0.05 (95% CI: 76.2-97.2) at 2 years, and 85 ± 0.08 (95% CI: 64.5-94.6) at 3 years. Cox regression analysis demonstrated that sex (hazard ratio [HR]: 0.96; 95% CI: 0.15-6.23, p = 0.963), extent of the occlusion (HR: 0.28; 95% CI: 0.05-1.46, p = 0.130), calcium score (HR: 1.88; 95% CI: 0.31-11.27, p = 0.490), or type of endovascular reconstruction (HR: 0.80; 95% CI: 0.13-5.15, p = 0.804) did not affect primary patency. Secondary patency was 95.5% ± 0.04 (95% CI: 78.4-99.2) at 3 years. No patients required late conversion to open surgical bypass. Conclusions: Endovascular reconstruction for total occlusion of the infrarenal aorta and aorto–iliac bifurcation was successful using a combination of percutaneous and hybrid revascularization techniques. Estimated patency rates at 3 years of follow-up are promising and are unaffected by the extent of occlusion or type of revascularization.

Abstract
INTRODUCTION Surgical approach of aortoiliac occlusive disease (AOD) with aorto-bi-femoral graft or endarterectomy, has been the first line treatment with patency rates up to 90%. Nevertheless, this procedure has an early mortality rate of 4%. Vascular complications of aorto-bi-femoral graft have an average incidence of 5-10% and development of incisional hernia in 10% of the cases. The Covered Endovascular Reconstruction of Aortic Bifurcation or CERAB technique, as a new approach is shaping up to be a promising approach. However, there are few studies in Latin America and the Caribbean. MATERIALS AND METHODS Retrospective multicenter study. All patients treated with the CERAB technique between February 2015 and June 2021 in three hospitals. RESULTS A total of 9 patients (5 male and 4 female) were treated with the CERAB technique. Only one patient died. Of the total number of patients, 41.2% had a TASC II - C classification, and 58.8% had a TASC II - D classification. Complications included dissection in only 2 patients, massive bleeding in 1 patient and hematoma in 3 patients. The average number of days in critical care was 1.2 days and 2.6 in hospitalization. Two patients required endovascular reintervention. Primary patency was present in 66.7% of the patients. DISCUSSION The CERAB technique presents a low morbidity and mortality with an 88.9% of technical success rate. None of our patients needed Chimney CERAB procedure. Our results are similar to those reported in the literature, where they report primary patency rates between 82% and 97%.

Abstract
PURPOSE The gold standard for the treatment of complex (TASC II C and D) atherosclerotic aortoiliac lesions is still open surgical repair. Endovascular techniques have a lower mortality and morbidity rate but this comes at the cost of worse patency rates when compared with open repair. Improved short- and mid-term results have been reported using the covered endovascular reconstruction of aortic bifurcation (CERAB) technique. The aim of this study was to report our initial experience with the CERAB technique and report long-term patency rates. MATERIALS AND METHODS All patients treated with the CERAB technique between 2012 and 2018 were prospectively registered in an institutional database and included in this study. Patient demographics, characteristics, symptoms, procedural, and follow-up details were collected and analyzed retrospectively. Perioperative complications and reinterventions were also identified. The Kaplan-Meier survival method was used to assess cumulative rates of patency. RESULTS A total of 44 patients were treated with the CERAB technique and included in this study. The majority of the treated aortoiliac occlusions were classified as complex: TASC II C (n=7; 15.9%) or TASC II D (n=25; 56.8%). Primary patency rate at 60 months was 83.3%, assisted primary patency was 90.9% and secondary patency 95%. No significant differences were found in patency rates comparing noncomplex (TASC II A and B) and complex (TASC II C and D) aortoiliac lesions. Seven patients (15.9%) required at least one additional procedure to maintain either assisted primary patency or secondary patency during follow-up. The 30-day complication rate in this series was 20.5% (n=9), of which 55.6% (n=5) were minor complications. All major 30-day complications (n=4) occurred during or directly after the CERAB procedure. Thirty-day mortality was 0%. No limb occlusions occurred within 30 days of the procedure. CONCLUSION Good long-term patency rates can be achieved with the CERAB technique to treat aortoiliac stenosis or occlusions while maintaining advantages associated with endovascular interventions. This remains true even when a CERAB is used to treat complex aortoiliac lesions. An endo-first approach to treat complex aortoiliac lesions seems viable.
