Abstract OBJECTIVES Our objective was to report the outcomes of fenestrated/branched endovascular aneurysm repair of thoraco-abdominal aortic aneurysms (TAAAs) with endografts. METHODS Between January 2010 and April 2018, patients with TAAAs, considered at high surgical risk for open surgery and treated by Cook-Zenith fenestrated/branched endovascular aneurysm repair, were prospectively enrolled and retrospectively analysed. The early end points were 30-day/hospital mortality rate, spinal cord ischaemia and 30-day cardiopulmonary and nephrological morbidity. Follow-up end points were survival, patency of target visceral vessels and freedom from reinterventions. RESULTS Eighty-eight patients (male: 77%; mean age: 73 ± 7 years; American Society of Anesthesiologists 3/4: 58/42%) were enrolled. Using Crawford’s classification, 43 (49%) were types I–III and 45 (51%) were type IV TAAAs. The mean aneurysm diameter was 65 ± 15 mm. Custom-made and off-the-shelf endografts were used in 60 (68%) and 28 (32%) cases, respectively. Five (6%) patients had a contained ruptured TAAA. The procedure was performed in multiple steps in 42 (48%) cases. There was 1 (1%) intraoperative death. Five (6%) patients suffered spinal cord ischaemia with permanent paraplegia in 3 (3%) cases. Postoperative cardiac and pulmonary complications occurred in 7 (8%) and 12 (14%) patients, respectively. Worsening of renal function (≥30% of baseline level) was detected in 11 (13%) cases, and 2 (2%) patients required haemodialysis. The 30-day and hospital mortality rates were 5% and 8%, respectively. The mean follow-up was 36 ± 22 months. Survival at 12, 24 and 36 months was 89%, 75% and 70%, respectively. The patency of target visceral vessels at 12, 24 and 36 months was 92%, 92% and 92%, respectively. Freedom from reinterventions at 12, 24 and 36 months was 85%, 85% and 83%, respectively. CONCLUSIONS The endovascular repair of TAAAs with fenestrated/branched endovascular aneurysm repair is feasible and effective with acceptable technical/clinical outcomes at early/midterm follow-up.

Purpose: This study describes technical success, feasibility, and early results of fenestrated and branched endovascular aortic repair (F/B-EVAR) for treatment of thoracoabdominal aortic aneurysms (TAAAs) or pararenal aneurysms with more than 4 target visceral vessels (TVs) due to renovisceral arterial anatomical variations. Materials and Methods: Patients with TAAAs or pararenal aortic aneurysms who had more than 4 TVs due to renovisceral arterial anatomical variations of renal, celiac, and/or superior mesenteric arteries and received F/B-EVAR between January 2017 and September 2019 at a single aortic center were included in this study. We analyzed technical success, feasibility, and early outcomes. Results: Twelve patients (mean age 70±10 years, 9 males) were included. The anatomical variations included 6 right accessory renal arteries, 8 left accessory renal arteries, and 1 celiac artery variant. Stent-grafts were fenestrated, branched or combined in 6, 5, or 1 patients, respectively. The mean operating time was 346±120 minutes, the mean fluoroscopy time was 80±29 minutes, and the mean radiation dose area product was 430±219 Gy·cm2. The mean contrast volume was 129±45 mL. The total number of TVs was 64; 5 TVs in 9 patients, 6 in 2 patients, and 7 in 1 patient. Technical success was achieved in all cases. The mean intensive care unit stay was 6±5 days, and the mean total hospital stay was 14±10 days. One patient died early (30-day). Early morbidities included respiratory complication in 1 patient, renal insufficiency in 1 patient, and wound infection in 2 patients. No spinal cord ischemia, stroke, or bowel ischemia occurred. Early computed tomography angiography showed 100% patency of the bridging covered stents and TVs. The mean follow-up was 13±4.3 months. No mortality or adverse major event occurred during the follow-up. Two patients with developed type Ic endoleak related to 1 right renal artery and 1 celiac artery covered stent. Patency of the TVs during follow-up was 100%. Conclusion: The use of F/B-EVAR for the treatment of TAAA with more than 4 TVs due to renovisceral arterial anatomical variations in our own experience is feasible and not related to increased morbidity and mortality.

Abstract Purpose To report the technical details and outcomes of the endovascular repair of two cases of de novo post-stenotic aortic coarctation aneurysms complicated by complex collateral supply. Case presentations Two patients with thoracic aortic aneurysms complicated by complex aneurysm sac collaterals distal to a previously untreated thoracic aortic coarctation have been treated at our institution. Open surgical intervention was deemed to carry a high risk of haemorrhage due to the degree and complexity of arterial collateralisation. In the first case, selective embolisation of collateral vasculature was performed prior to successful exclusion of the aneurysm with a thoracic endovascular stent-graft and then balloon-expandable stent dilatation of the coarctation stenosis. In the second case, the additional technique of using a jailed sheath within the aneurysm sac allowed for selective embolisation of previously inconspicuous collaterals after deployment of the stent-graft and stent combination. Results Technical success was achieved in both patients with successful occlusion of the aneurysm, with no recorded complications or aneurysm sac perfusion in the long and medium term follow up periods respectively. Conclusion De novo post stenotic aortic coarctation aneurysms are rare. Endovascular repair is a safe and durable technique that provides a less invasive alternative to open surgical repair. The use of a jailed sheath allows for complete selective embolisation of complex collaterals avoiding a type II aneurysm endoleak.

Objectives Revascularization according to the angiosome concept is of proven importance for limb salvage in chronic limb threatening ischaemia but it is not always practicable. Bifurcated bypasses could be considered as an option when an endovascular approach is not feasible or has already failed and a single bypass would not allow direct revascularization of the ischaemic area. Bifurcated bypasses are characterized by landing on two different arteries, the main artery (in direct continuity with the foot vessels) and the secondary one (perfusing the angiosome district). The aim of this study is to evaluate the safety and effectiveness of bifurcated bypass in chronic limb threatening ischaemia. Methods Thirty-five patients were consecutively treated with a bifurcated bypass for chronic limb threatening ischaemia from January 2014 to December 2019 in a single vascular surgery centre. Data from clinical records and operative registers were collected prospectively in an electronic database and retrospectively analysed. Primary and primary assisted bypass patency, amputation-free survival, morbidity and mortality rates at 12 and 24 months were analysed. Results Mean follow-up period was 25.1 months (range 2–72 months). Thirty-six bifurcated bypasses were performed on 35 patients (age 75.3 ± 7.2 years; 69.4% were male). According to Wound, Ischemia, foot Infection classification 22.2% belonged to stage 3 and 77.8% to stage 4 and the mean Rutherford’s class was 5.1 ± 0.7. Immediate technical success was 100%. Early mortality and morbidity rates were respectively 5.5%, and 33.3%; foot surgery was performed in 50% of cases with wound healing in all patients. Primary patency and primary assisted bypass patency were 96.7% and 100% at 6 months; 85.2% and 92% at 12 months, 59.9% and 73.4% at 24 months, respectively. Amputation-free survival at 12 and 24 months was, respectively, 95.6% and 78.8%. Overall survival rates at 12 and 24 months were respectively 94.4% and 91.6%. Conclusions Bifurcates bypass can provide good results in patients with chronic limb threatening ischaemia without endovascular option, especially in diabetic ones. Bifurcated bypass is a complex surgical solution, both to be planned and performed, and it is quite invasive for frail patients that should be accurately selected.

Purpose: To evaluate the efficacy of the Active Seal technology employed in the AFX endovascular aortic aneurysm system (AFX), during endovascular aneurysm repair (EVAR) in patients with abdominal aortic aneurysms (AAAs) having a conical proximal neck. Materials and Methods: A retrospective analysis of the EVAR for AAA with a conical proximal neck using the AFX was performed at 17 Japanese hospitals between January 2016 and August 2020. The conical proximal neck was defined as a cone-shaped proximal neck, with more than 10% diameter increase within a 15 mm length at the proximal landing zone. All anatomical analyses were performed in the core laboratory, and cases with parallel walls within the proximal neck adequate for the landing zone were excluded from the study. Results: This study included 53 patients, but only 39 patients (mean age, 76.6 ± 6.7 years; 87.0% males; mean aneurysm diameter, 52.0 ± 8.0 mm) were analyzed after being characterized as having a pure conical neck by the core laboratory. The mean proximal neck diameters at the lower renal artery and proximal edge of the aneurysm were 20.0 ± 2.9 mm and 27.5 ± 4.9 mm, respectively. The mean proximal neck length was 21.5 ± 6.0 mm. Instructions for use violations other than the conical neck were observed in 15 patients (38.5%). The VELA cuff was used in all cases; however, additional proximal cuff was required in 9 more cases (23.1%). The Active Seal technology was able to significantly extend the proximal sealing zone from 21.5 ± 6.0 to 26.0 ± 12.2 mm ( p = .047). Thirty-six patients completed the 12-month follow-up (one patient was lost to follow-up, and 2 patients died from causes unrelated to the aneurysm), and there were no type-1a and 3 endoleaks with only one reintervention (2.6%) related to type 1b endoleak in the 12-month period. Furthermore, there was no significant enlargement of the proximal neck diameter at 12 months (at 1 month: 20.6 ± 3.4 mm and at 12 months: 21.3 ± 3.8 mm; p = .420). Conclusion: The Active Seal technology of the AFX significantly extended the proximal seal zone and no type-1a endoleak and proximal neck dilation was observed in patients with conical proximal neck at 12 months.

Introduction We performed a single-center nonrandomized study on patients who underwent endovascular aneurysm repair using polymer-filled or other self-expanding endografts. Methods Consecutive patients with asymptomatic infrarenal abdominal aortic aneurysms who underwent endovascular repair were retrospectively reviewed. They were divided into a polymer-filled ( n = 20) or self-expanding group ( n = 42). Baseline characteristics, operative mortality and morbidity, and follow-up data were compared. Results Aneurysm diameter, neck and iliac morphologies did not differ between the two groups. Technical success was 100%. The 30-day mortality was 0% and 2.4% in the polymer-filled and self-expanding group, respectively. At a mean follow-up of 17 months, the changes in sac size were −2.1 mm and −5.1 mm ( p = 0.144) at one year, and −3.5 mm and −7.7 mm ( p = 0.287) at 2 years in the polymer-filled and self-expanding group, respectively. The polymer-filled group had 7 (35%) type II endoleaks, and the self-expanding group had 1 (2.4%) type Ia and 13 (31%) type II endoleaks. Neck diameter remained stable in the polymer-filled stent-grafts whereas there was progressive neck degeneration in the self-expanding group. The rates of reintervention and overall survival were similar in both groups. The presence of an endoleak was the only predictor of non-regression of the aneurysm (odds ratio = 17.00, 95% confidence interval: 4.46–64.88, p < 0.001). Conclusion Polymer-filled endografts had similar safety, effectiveness, and durability to other self-expanding endografts. The major advantage is the small iliofemoral access. They also have the potential long-term benefit of a more stable neck.

INTRODUCTION Some studies have considered abdominal aortas of 2.6–2.9 cm diameter (ectatic aortas) at age 65 years as being abnormal and have recommended surveillance, whereas others have considered these normal and surveillance unnecessary. It is, therefore, not clear how to manage patients with an initial aortic diameter between 2.6–2.9 cm detected at screening. The aim of this study was to evaluate growth rates of ectatic aortas detected on initial ultrasound screening to determine if any developed into clinically significant abdominal aortic aneurysms (AAAs; > 5.0 cm) and clarify the appropriate surveillance intervals for these patients. PATIENTS AND METHODS Data were obtained from a prospective AAA screening programme which commenced in 1992. The group of patients with initial aortic diameters of 2.6–2.9 cm with a minimum of 1-year follow-up were included in this study (Group 2). This was further divided into two subgroups (Groups 3a and 3b) based on a minimum follow-up interval obtained from outcome analysis. Mean growth rate was calculated as change in aortic diameter with time. The comparison of growth rates in Groups 3a and 3b was performed using the t-test. The number and proportion of AAAs that expanded to ≥ 3.0 cm and ≥ 5.0 cm in diameter were also calculated. RESULTS Out of 999 patients with AAA ≥ 2.6 cm with minimum 1-year follow-up, 358 (36%) were classified as ectatic aortas (2.6–2.9 cm) at initial ultrasound screening with the mean growth rate of 1.69 mm/year (95% CI, 1.56–1.82 mm/year) with a mean follow-up of 5.4 years. Of these 358 ectatic aortas, 314 (88%) expanded into ≥ 3.0 cm, 45 (13%) expanded to ≥ 5.0 cm and only 8 (2%) expanded to ≥ 5.5 cm over a mean follow-up of 5.4 years (range, 1–14 years). No ectatic aortas expanded to ≥ 5.0 cm within the first 4 years of surveillance. Therefore, the minimum follow-up interval was set at 4 years and this threshold was then used for further analysis. The mean growth rate in Group 3a (< 5.0 cm at last scan) was 1.33 mm/year (95% CI, 1.23–1.44 mm/year) with a mean follow-up of 7 years compared to Group 3b (≥ 5.0 cm at last scan) with the mean growth rate of 3.33 mm/year (95% CI 3.05–3.61 mm/year) and a mean follow-up of 8 years. The comparison of mean growth rates between Groups 3a and 3b is statistically significant (t-test; T = 13.00; P < 0.001). CONCLUSIONS One-third of patients undergoing AAA screening will have ectatic aortas (2.6–2.9 cm) and at least 13% of these will expand to a size of ≥ 5.0 cm over a follow-up of 4–14 years. A threshold diameter of 2.6 cm for defining AAAs in a screening programme is recommended and ectatic aortas detected at age 65 years can be re-screened at 4 years after the initial scan. A statistically significant difference was found in the growth rates of ectatic aortas with minimum 4 years follow-up, expanding to ≥ 5.0 cm compared to those less than 5.0 cm at last surveillance scan. Further studies are required to test the hypothesis of whether growth rate over the first 4 years of surveillance will identify those who are most likely to expand to a clinically significant size (> 5.0 cm).

Abstract: Between 2015 and 2017 there was a 40% increase in daily hemodialysis, according to the REIN database. This increase concerns 1% of patients and the private sector remains under-represented. Our retrospective study aims to describe the clinical features, the organizational and medico-economic specificities of this technique in a private hemodialysis center. Methods: We included 12 dialyzed patients trained on Nx Stage® machine from February 2020 to April 2021. Data were retrospectively obtained through review of our electronic medical records (EUCLID®). Results: Of the 12 patients trained, 11 dialyzed from home, with an average follow-up of 9 months (1-14). The average age was 45 with a sex ratio of 4/8 (M/W), and a median Charlson score of 3 (2-4). The average residual urinary output was 700 mL/24h, and 50% of patients were anuric. 100% of patients had an arteriovenous fistula and were cannulated using the buttonhole technique. 9 patients are on a transplant list. One patient needed anticoagulants. The mean training time was 35 days (28-35). 83% of patients were dialyzed 6 days a week with an average duration of 210 minutes (130-150) per session. The average volume of dialysate was 24.85 liters. One patient developed an allergy to the PUREMA® membrane. Pre-dialytic hemoglobin, serum creatinine, urea, phosphoremia and B2-microglobuline are stable at 9 months with improvement in metabolic acidosis. Conclusion: DHHD allowed a better socio-professional integration. One patient received a transplant and 3 patients resumed professional activity.

Statin Use

Background: Management of lipids is vital in patients with underlying coronary artery disease (CAD). According to the American College of Cardiology (ACC) guidelines, all patients with CAD should have low density lipoproteins (LDL) goals to be less than 100 mg/dl with the therapeutic option of treatment to less than 70 mg/dl. This can be achieved using multiple lipid lowering agents, however statin use is encouraged in CAD patients due to its multiple beneficial effects. Methods: We conducted a retrospective cohort study focusing on lipid management and statin use in 857 veterans undergoing percutaneous coronary intervention (PCI) between September 2004 and December 2009 at the Jesse Brown Veterans Hospital in Chicago, IL. Values were collected both pre-intervention as well as at six month follow up. Results: Both pre and post PCI, focus was maintained on the total cholesterol as well as the LDL levels. The mean total cholesterol prior to intervention was 166mg/dl and decreased to150mg/dl at six month follow up. The LDL mean pre-PCI was 98mg/dl and at six months the mean LDL decreased to 86mg/dl. With regards to ACC guidelines, the percent at goal for LDL less than 100mg/dl increased from 59% pre-PCI to 74% post-PCI Furthermore, treatment to less than 70mg/dl increased from 22 to 32% at six months. Lastly, the use of statins increased from 72 to 89%. Conclusions: There were in improvements in both total cholesterol and LDL values at six months post-PCI. There were also improvements in the percentage of patients who met the ACC recommended goal of LDL cholesterol less than 100mg/dl and the suggested goal of 70mg/dl. At six months, there was also an increase in usage of statin therapy.
