Impact of isolated type 2 endoleak on subsequent cardiovascular events and mortality.

OBJECTIVE: Assess subsequent cardiovascular events and all-cause mortality in patients with intact AAA treated by EVAR according to the existence of isolated EL2 at 1 year after EVAR implantation. METHODS: This retrospective, single-centre study included patients treated with EVAR between 2010 and 2017 in the vascular surgery department of the University Hospital of Lyon with a infrarenal AAA > 50 mm. The baseline clinical characteristics collected just before EVAR were retrieved from electronic patient records of our institution. AAA characteristics, procedure and the one-year post-operative CTA were reported. Study endpoints, major adverse cardiovascular events (MACE), major adverse lower extremity events (MALE) and all-cause mortality, were recorded during follow-up. Patients were divided into 2 groups according to the presence of isolated EL2 (EL2 +) or absence (EL2 -) of any endoleak on CTA at 1 year. MACE, MALE and all-cause mortality were compared between both groups. RESULTS: During the study period, 589 patients were treated by endovascular surgery and 207 were included. According to the CTA results at 1 year, 60 patients (29%) were included in the EL2 + group, and 147 patients (71%) in the EL2 - group. A total of 109 patients (53%) experienced a MACE or MALE; significantly fewer patients in the EL2 + than in the EL2 - group did so (p = .009). There were 47 patients (23%) who experienced at least one MALE, and the frequency was significantly lower in the EL2 + group (p = .017). CONCLUSION: Patients with AAA treated by EVAR who did not develop EL2 at one year, were at higher risk of MALE during follow-up. This might be explained by more frequent symptomatic LEPAD at baseline in this group. These patients therefore require a closer follow-up and strict control of cardiovascular risk factors to prevent cardiovascular morbi-mortality.

Dissection of the Celiac Trunk Is a Mild Disease.

BACKGROUND: The purpose of this study was to assess whether the presence of an aneurysmal or dissecting arterial disease was a risk factor of poor prognosis in patients presenting a dissection of the celiac trunk (CT). METHODS: All patients presenting a CT dissection between January 1, 2014, and June 30, 2022, were included. Patients with a CT dissection due to the extension of an aortic dissection were excluded. Les antécédents familiaux de dissection, de maladie anévrysmale, de maladie athéromateuse ou du tissu conjonctif, la pratique d'une activité physique ou sportive, un effort inhabituel les jours précédant la dissection ainsi qu'un traumatisme étaient recherchés. Family history of dissection, aneurysmal disease, atheromatous or connective tissue disease, physical activity or sport, an unusual effort in the days prior to the dissection and trauma were sought after. Ischemic or aneurysmal complications in the acute phase and the evolution of the dissection were evaluated and compared between patients with an isolated dissection and those presenting an aneurysmal or dissecting arterial disease. RESULTS: 45 patients were included in the study. Twenty-three (51.1%) patients presented with symptomatic CT dissection, and 22 (48.9%) with asymptomatic CT dissection. All the patients initially had medical management alone. The mean follow-up was 32 ± 25 months and all patients were asymptomatic at the time last news. 24 (53.3%) presented an isolated CT dissection, and 21 (46.7%) a CT dissection associated with aneurysmal or dissecting arterial disease. There was no significant difference between patients with an isolated CT dissection and those with an associated dissecting or aneurysmal pathology. CONCLUSIONS: CT dissection is a stable disease in the midterm, which makes it a mild arterial pathology, with or without aneurysmal or dissecting anomalies in another territory. The mechanical stress exerted on the CT by the arcuate ligament could be responsible for parietal trauma and favor the occurrence of a CT dissection.

American Society of Anesthesiologists-Physical Status Classification As An Independent Risk Factor of Surgical Site Infection After Infra-Inguinal Arterial Bypass.

OBJECTIVES: The present study aimed to assess whether high-risk American Society of Anesthesiologists (ASA)-Physical Status was an independent risk factor for the development of surgical site infection (SSI) after infra-inguinal lower extremity bypass (LEB). SUMMARY OF BACKGROUND DATA: The ASA-Physical Status Classification System assesses the overall physical status preoperatively. ASA-Physical Status is associated with postoperative morbidity and mortality. However, limited data are available on how ASA-Physical Status Class affects the development of SSI after infra-inguinal LEB. METHODS: Patients who had undergone infra-inguinal LEB from January 1, 2015 to December 31, 2018, for obliterative arteriopathy or popliteal aneurysm at our university hospital were included. SSI risk factors were identified using multivariable logistic regression. The length of hospital stay, major limb events (MALE), major adverse cardiovascular events (MACE), and all-cause mortality were compared for patients with SSI versus those without SSI 3 months and 1- year of follow-up after the index surgery. RESULTS: Among the 267 patients included, 30 (11.2%) developed SSI during the 3-month period and 32 (12%) at 1 year. ASA-Physical Status ≥3 [odds ratio (OR): 3.7, 95% confidence interval CI) 1.5-11.1], emergency surgery (OR: 2.7, 95% CI 1.2-6.0), general anesthesia (OR: 2.8, 95% CI 1.3-6.1), and procedure performed by a junior surgeon (OR: 2.7, 95% CI 1.3-6.0) were independently associated with SSI. At 3 months and 1 year, SSI was significantly associated with MALE (including surgical wound debridement, subsequent thrombectomy, major amputation), length of hospital stay, and all-cause mortality. CONCLUSION: The ASA-Physical Status should be considered in medical management when an infra-inguinal LEB is considered in frail patients, to prevent surgical complications.

Effectiveness of an individualized home-based physical activity program in surgery-free non-endarterectomized asymptomatic stroke patients: a study protocol for the PACAPh interventional randomized trial.

BACKGROUND: Carotid atherosclerotic plaques remain silent until their rupture, which may lead to detrimental ischemic events such as strokes. This is due, in part, to intraplaque hemorrhages (IPH) and the resulting inflammatory processes, which may promote carotid plaque vulnerability. Currently, the benefits of carotid endarterectomy remain unclear for asymptomatic patients. Interestingly, the completion of physical activity (PA) may have beneficial effects; however, the paucity of current data warrants robust longitudinal interventions. We therefore aim to study the effects of a 6-month longitudinal personalized home-based PA program on IPH, biological, and inflammatory markers in asymptomatic stroke patients. METHODS: Eighty patients (≥ 18 years old) will be recruited for the Physical Activity and Carotid Atherosclerotic Plaque Hemorrhage (PACAPh) clinical trial from the Hospices Civils de Lyon. Patients will be eligible if they present with carotid stenosis ≥ 50% and are asymptomatic from any ischemic events for at least 6 months. Recruited patients will be randomized into either a PA or a control group, and assessed at baseline and after 6 months. At both time points, all patients will be assessed using magnetic resonance imaging to assess IPH, blood sampling to measure inflammatory markers and monocytic phenotyping, PA and sedentary behavior questionnaires, 6-min walking test, and maximal isometric quadricep contraction test. The randomized PA intervention will consist of reaching a daily walking step goal individually tailored to each patient. Steps will be collected using a wirelessly connected wristband. The number of steps completed by individuals in the PA group will be re-evaluated bimonthly to encourage walking habits. DISCUSSION: The PACAPh study is the first of its kind representing a feasible, easily accessible therapeutic strategy for asymptomatic stroke patients. We hypothesize that the personalized home-based PA program will reduce IPH and modulate inflammatory and biological parameters in patients presenting with carotid plaques. If the results of the PACAPh study prove to be beneficial on such health parameters, the implementation of such kind of intervention in the daily treatment of these patients would be an advantageous and cost-effective practice to adopt globally.
