Background: Most patients undergo uneventful surveillance after endovascular aneurysm repair (EVAR), and therefore, unmodified surveillance protocols are ineffective. An example of a modified follow-up protocol was introduced by the European Society for Vascular Surgery (ESVS) in January 2019. One feature of this protocol is that for the patients with adequate sealing and without any detectable endoleak at 30 days, the next scheduled follow-up could be at 5 years. The purpose of this study was to analyze retrospectively the applicability of this protocol.
Methods: Between 2005 and 2013, 348 patients were treated electively for abdominal aortic aneurysm (AAA) with a standard EVAR. All patients were annually followed and they were retrospectively fitted into the ESVS follow-up protocol based on imaging findings.
Results: The mean follow-up was 74 months (standard error 2.1; range, 0-165 months). Thirty-day mortality was 1.1% (n = 4). Imaging data for those surviving the first 30 days were available for 98.8% (n = 340) subjects. At a 1-month control examination, 79.3% (n = 276) of the patients had no detectable endoleak and sealing was adequate (≥1 cm). Of those patients, with the lowest risk, 11.6% (n = 32) required reintervention for graft-related complication during the next 5 years. In all, complications requiring treatment that would have been missed by following the suggested protocol included type 1A endoleak (n = 7), type 1B (n = 10), type 2 (n = 7), migration (n = 2), thrombosis (n = 10), kinking (n = 1), and ruptured AAA (n = 6). The sensitivity of 30-day computed tomography angiogram was 34.9% (95% confidence interval 21.01-50.93%) and specificity 83.3% (95% confidence interval 78.57-87.41%) for finding significant complications during first 5 years.
Conclusions: Based on our findings, by following the example ESVS follow-up protocol, we would have missed major life-threatening complications. Significant stent-graft failures occur during the first 5 years, even for those with noncomplicated post-EVAR findings in the first computed tomography angiogram at 1 month.

The goal of this study was to determine how radiologists' rating of image quality when using 0.5T Magnetic Resonance Imaging (MRI) compares to Computed Tomography (CT) for visualization of pathology and evaluation of specific anatomic regions within the paranasal sinuses. 42 patients with clinical CT scans opted to have a 0.

Body composition abnormalities are prognostic markers in several types of cancer, including colorectal cancer (CRC). Using our data distribution on body composition assessments and classifications could improve clinical evaluations and support population-specific opportune interventions. This study aimed to evaluate the distribution of body composition from computed tomography and assess the associations with overall survival among patients with CRC.

Engineering plastics are finding widespread applications across a broad temperature spectrum, with additive manufacturing (AM) having now become commonplace for producing aerospace-grade components from polymers. However, there is limited data available on the behavior of plastic AM parts exposed to elevated temperatures. This study focuses on investigating the tensile strength, tensile modulus and Poisson's ratio of parts manufactured using fused filament fabrication (FFF) and polyetheretherketone (PEEK) plastics doped with two additives: short carbon fibers (SCFs) and multi-wall carbon nanotubes (MWCNTs).

The position of the mental foramen is reported to change with age. This study aimed to examine age-related changes in the position of the mental foramen in men and women. Among 200 cases (age 21-100 years; 400 foramina) that underwent postmortem computed tomography, 109 (age 21-93 years; 218 foramina) with mandibular first and second premolars were examined using image analysis software to classify the position of the mental foramen according to Fishel's classification, and the χ² test was performed.

This study aimed to investigate the cutoff values of standardized uptake values (SUVs) and their accuracy using single-photon emission computed tomography-computed tomography (SPECT-CT) for temporomandibular joint (TMJ) osteoarthritis (OA) based on magnetic resonance imaging (MRI) and clinical examination. We included 106 joints of 53 patients with TMJ OA. SUVmax and SUVpeak of each TMJ was measured.
