To investigate abdominal aortic aneurysm (AAA) screening rates in the 6 months before and after the introduction of updated Canadian Task Force on Preventive Health Care (CTFPHC) guidelines to determine effects on practice patterns, as well as to determine whether certain patient characteristics impact AAA screening rates.
Retrospective chart review.
Academic family health centre in London, Ont.
Male patients between the ages of 65 and 80.
Screening rates for AAA before and after the guideline update were compared using the normal approximation of the binomial distribution. Analysis of demographic characteristic effects on screening rates was completed with the Fisher exact test. Number of visits to the clinic with a primary care provider within the study period and imaging type were collected.
Of the 266 patients included in the study, 160 patients were eligible for screening at the start of the study period, 6 months before publication of the CTFPHC AAA guideline. Individuals eligible for screening visited the clinic an average (SD) of 2.44 (1.82) times in the 6 months before and 2.66 (1.99) times in the 6 months after. Overall, 69 individuals had AAA screening completed and 9 had a discussion of AAA screening without any imaging, for a total uptake rate of 88.5% for those who had screening recommended. The overall imaging rate was 48.9%. There was no statistically significant difference in screening rates between the time periods (P=.337) among those eligible for screening. For demographic characteristics for risk stratification, 7 individuals had a documented family history, of whom 5 had imaging of their abdominal aorta performed, plus 1 additional individual who had screening recommended but not completed. This was not statistically significant relative to the total population (P=.0598). Positive smoking status (active or ex-smoker) was more common, with 135 individuals having a relevant smoking history. Approximately half of these current and former smokers (68 individuals [50.4%]) had any sort of abdominal aortic imaging performed or recommended, which was not statistically significantly different compared with non-smokers (62 of 126 imaging performed or recommended, 49.2%; P=.9016).
Screening practices did not change appreciably with the introduction of the CTFPHC AAA screening guidelines. Further research is needed to improve AAA screening rates. It is worth exploring electronic medical record-based reminders, nursing staff involvement in screening, screening programs via public health, and point-of-care ultrasound screening in a primary care setting.

BACKGROUND: To describe the outcomes of the endovascular reconstruction of TASC C/D lesions involving the infrarenal aorta and aortic bifurcation with different techniques.
METHODS: This is an observational, retrospective, single-center study. In a 5-year period, we selected all the patients treated with an endovascular procedure for an aorto-iliac TASC C/D lesion involving the infrarenal aorta and/or the aortic bifurcation. Early (<30 days) outcomes were mortality, major amputation, and thrombosis. Late mid-term (1 and 3 years) outcomes were primary, assisted primary and secondary patency, limb salvage rate, and freedom from reintervention.
RESULTS: A total of 87 patients were treated during the index period. Kissing covered stent (cKS), covered reconstruction of aortic bifurcation (CERAB), and unimodular bifurcated AFX Unibody stent-graft (Bif-SG) implantation were performed in 35 (40.4%), 26 (29.8%), and 26 (29.8%) cases, respectively. Bif-SG group included 11 (11/26, 42.3%) patients treated for abdominal aortic aneurysm associated with the obstruction of the aortic bifurcation. Technical success was achieved in all cases and no ruptures or conversions to open surgery were recoded. Median follow-up age was 18 months (interquartile range [IQR], 8-34). Overall primary patency rate was 91.2% (95% confidence interval [CI]: 81.3-95.9) at 1 year and 83.5% (95% CI: 69.6-91.4) at 3 years. Assisted primary patency was 96.9% (95% CI: 87.8-99.2) at 1 and 3 years. Secondary patency was 97.8% (95% CI: 85.5-99.6) at 3 years. Limb salvage rate was 98.6% (95% CI: 90.1-99.7) at 1 and 3 years and, freedom from reintervention was 98.4% (95% CI: 88.9-99.7) at 1 year and 87% (95% CI: 66.1-95.4) at 3 years. Univariate analysis did not identify any factor affecting primary patency rate.
CONCLUSIONS: Endovascular reconstruction in severe aorto-iliac obstructions using advanced techniques offered promising mid-term patency rates and profiles of safety. The variety of reconstructive configurations allows surgeons to customize on patients\' anatomies the type of revascularization.

BACKGROUND: Vascular graft infection in the aortoiliac territory (abdominal VGI) is undoubtedly one of the most serious complications in vascular surgery. The treatment is burdened with high mortality and morbidity rates. In 2020, the Guidelines on the Management of Vascular Graft and Endograft Infections were published by the European Society for Vascular Surgery (ESVS). In the light of these guidelines, we decided to review retrospectively all patients who presented to our institution with abdominal VGI.
METHODS: Retrospective observational study of patients presented with abdominal VGI treated in our institution between 20112019 (9 years). The primary goal was to elucidate the rate of vascular graft infection in aortoiliac reconstructions performed between 20112019 and also the mortality rate in the patient cohort operated for this complication. The secondary goals were to evaluate the success rate and the complication rate in different types of reconstructions.
RESULTS: In the defined period between 20112019 we performed 363 open aortoiliac reconstructions. During the same period we treated altogether 15 patients with abdominal VGI, whose primary reconstruction was mostly performed before 2011 (11 patients). In our cohort of patients who underwent reconstruction between 20112019 we observed a graft infection only in 4 cases (1.1%). In the group of 15 patients with abdominal VGI, the male gender prevailed (14 patients). The mean age at the time of primary reconstruction was 61 years. Most of our reconstructions were performed for occlusive disease (14 cases). All infected grafts were aortobifemoral (1 unilateral aortofemoral). They were all late infections with an average presentation time of 61 months since the primary reconstruction (15180 months). Early mortality rate was as high as 27% (4 patients) and overall mortality was 40%. The secondary reinfection rate after primary treatment was 33%.
CONCLUSIONS: Treatment of abdominal VGI is still burdened with high mortality and morbidity rates. The current ESVS guidelines provide valuable guidance for the diagnosis and management of VGI. It nevertheless remains obvious that the treatment needs to be tailored individually in a multidisciplinary team environment.

UNASSIGNED: To assess the appropriateness of abdominal aortic aneurysm (AAA) screening with ultrasound (US) and potential cost savings by adhering to guidelines and reviewing prior imaging.
UNASSIGNED: Screening aortic US performed in Nova Scotia from January 1 to April 30, 2019, were reviewed. Patient sex, age, risk factors, and study result (negative, <2.5 cm; ectatic, 2.5-2.9 cm; positive for AAA, ≥3 cm) were recorded. Previous imaging tests were reviewed for the presence/absence of aortic ectasia or aneurysm. Appropriateness was based on the Canadian Task Force on Preventive Health Care (CTFPHC) and the Canadian Society of Vascular Surgery (CSVS) guidelines. The number of potentially averted US, subsequent missed positive findings, and cost savings (over the 4-month period) were calculated according to: 1) each guideline; and 2) each guideline combined with review of imaging done 0 to 5 years and 0 to 10 years previously.
UNASSIGNED: There were 17 (4.6%) of 369 ectatic aortas and 18 (4.9%) of 369 AAAs. The number of potentially averted examinations, missed ectatic aortas, missed AAAs, and cost savings were as follows, respectively: CTFPHC, 222 (60.2%) of 369, 8, 7, and CAD$20 501.70; CSVS, 117 (31.7%) of 369, 4, 2, and CAD$10 804.95. The model that would yield the greatest cost savings and fewest missed positive findings was the combination of CSVS guidelines with review of prior imaging within 5 years; this would avert 189 (51.2%) of 369 examinations, save CAD$17 454.15 over 4 months, and miss only 2 AAAs and 2 ectatic aortas.
UNASSIGNED: Over half of aortic US screening tests can be safely averted by adhering to CSVS guidelines and reviewing imaging performed within 5 years.

BACKGROUND: Endovascular aneurysm repair (EVAR) is currently accepted as an alternative to open repair for the treatment of abdominal aortic aneurysm (AAA). Approximately 40-60% of AAA patients are not considered eligible for EVAR due to unfavorable anatomy. There is currently no consensus on the definition of \"hostile\" aortic neck for EVAR procedure.
METHODS: An Expert Panel (EP), made up of 9 Italian vascular surgeons from high-volume centers (>50 EVAR procedures/year), was assembled to share their opinion about the definition of hostile aortic neck anatomy for EVAR procedure. The process included a review of the current literature by the EP, a face-to-face meeting, and an on-line survey completed by the EP prior to and following the face-to-face meeting, using the Delphi method.
RESULTS: Of the 66 reviewed studies, only 38 (58%) reported at least 1 aortic neck hostility criterion. Five anatomic parameters were identified, namely, aortic neck length, aortic neck angulation, aortic neck diameter, conical neck, and presence of circumferential calcification. Based on the results of the first survey round, these criteria and related definitions were discussed in depth during the face-to-face meeting. For 3 parameters (aortic neck diameter, aortic neck angulation, conical neck), the agreement among the EP members was already high during the first survey round while for the remaining 2 (aortic neck length, circumferential calcification) it remarkably increased from the first to the second survey round. For each of these criteria, as well as combinations of at least 2 of these criteria, specific threshold values were identified above or below which a standard EVAR approach was not considered ideal by the EP due to high/moderate risk of complications.
CONCLUSIONS: EP agreed on the definition of 5 aortic neck hostility criteria, according to which they gave their opinion on the feasibility and risks of a standard EVAR approach. Further agreement will be needed and examined on the best nonstandard EVAR technique which may be offered in the presence of different combinations of hostility criteria.

BACKGROUND: To further strengthen the evidence base on the use of Resuscitative Endovascular Balloon occlusion of the Aorta (REBOA) we performed a Delphi consensus. The aim of this paper is to establish consensus on the indications and contraindications for the use of REBOA in trauma and non-trauma patients based on the existing evidence and expertise.
METHODS: A literature review facilitated the design of a three-round Delphi questionnaire. Delphi panelists were identified by the investigators. Consensus was reached when at least 70% of the panelists responded to the survey and more than 70% of respondents reached agreement or disagreement.
RESULTS: Panel members reached consensus on potential indications, contra-indications and settings for use of REBOA (excluding the pre hospital environment), physiological parameters for patient selection and indications for early femoral access. Panel members failed to reach consensus on the use of REBOA in patients in extremis (no pulse, no blood pressure) and the use of REBOA in patients with two major bleeding sites.
CONCLUSIONS: Consensus was reached on indications, contra indications, physiological parameters for patient selection for REBOA and early femoral access. The panel did not reach consensus on the use of REBOA in patients in pre-hospital settings, patients in extremis (no pulse, no blood pressure) and in patients with 2 or more major bleeding sites. Further research should focus on the indications of REBOA in pre hospital settings, patients in near cardiac arrest and REBOA inflation times.

The \"new\" and updated European Society for Vascular Surgery (ESVS) 2019 Clinical Practice Guidelines on the Management of Abdominal Aorto-iliac Artery Aneurysm, published in the 2019 January issue of the European Journal of Vascular and Endovascular Surgery, is an extensive document offering 125 recommendations of clinical importance on the management of AAA, accompanied by a comprehensive supporting text that summarizes the literature and motivates the positions made. Several new topics, not addressed in the previous guidelines, are included. Here we summarize the most important news in the new ESVS 2019 clinical practice guidelines on the management of abdominal aorto-iliac artery aneurysm.
