Patients with a type II endoleak and aneurysm growth (&gt;5 mm) were included. Patients with a patent inferior mesenteric artery connected to the endoleak were excluded for initial safety reasons. The endoleak cavity was translumbar punctured with cone-beam computed tomography (CT) and software guidance. Angiography of the endoleak was performed, all lumbar arteries connected to the endoleak were visualized, and AneuFix elastomer was injected into the endoleak cavity and short segment of the lumbar arteries. The primary endpoint was technical success, defined as successful filling of the endoleak cavity with computed tomography angiography (CTA) assessment within 24 hours. Secondary endpoints were clinical success defined as the absence of abdominal aortic aneurysm (AAA) growth at 6 months on CTA, serious adverse events, re-interventions, and neurological abnormalities.

Technical success was 100%; it was possible to puncture the endoleak cavity of all treated patients and to inject AneuFix. Clinical success at 6 months was 90%.

Estimating plaque solidity before the procedure may help operators penetrate calcified plaque with a guide wire. The aim of this study was to establish a method of measuring plaque solidity with noncontrast computed tomography (CT).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This retrospective, single-center study included consecutive patients who, between October 2020 and July 2022, underwent noncontrast 5 mm and 1 mm CTs before endovascular therapy to penetrate calcified plaque with a wire in the common femoral, superficial femoral, and popliteal arteries. Three cross-sectional CT slices were selected. To target a calcified plaque lesion, the operator identified a region of interest, which corresponded to 24×24 pixels, and Hounsfield unit (HU) values of each pixel were displayed on the CT image. The average HU values and the ratio of number of pixels of lower values (130-599 HU) represented plaque solidity. We used the Mann-Whitney-Wilcoxon rank-sum test and the chi-square test to compare the solidity of plaques penetrated and not penetrated by the wire.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;We evaluated 108 images of 36 calcified plaque lesions (in 19 patients). The wire penetrated 28 lesions (77.8%) successfully. The average HU value was significantly lower in the lesions that the wire penetrated than in the others, in both the 5 mm CT slices (434.7±86.8 HU vs 554.3±112.7 HU, p=0.0174) and 1 mm slices (497.8±103.1 HU vs 593.5±114.5 HU, p=0.0381). The receiver operating curve revealed that 529.9 and 533.9 HU in the 5 and 1 mm slices, respectively, were the highest values at which wires could penetrate. Moreover, at the lesions that were penetrates successfully, the ratio of number of lower HU value pixels was significantly higher both in 5 mm slice CTs (74.7±13.4 vs 61.7±13.1%, p=0.0347) and 1 mm (68.7±11.8 vs 57.1±11.4%, p=0.0174).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The use of noncontrast CT to evaluate plaque solidity was associated with successful wire penetration of calcified lesions in peripheral arteries.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Clinical impact: &lt;/strong&gt;This study revealed an association between the wire penetration inside calcified plaque and plaque solidity estimated using non-contrasted computed tomography. The mean Hounsfield unit values of three cross-sections in calcified plaques were associated with the successful wire penetration. This wire penetration difficulty is associated with extended procedure time, excessive radiation exposure, usage of extra contrast agents, and increased medical costs. Therefore, estimating calcified plaque solidity before procedure enables us to choose effective and lean procedures.

The mean maximum diameter of AAAs was 54.7±6.6 mm, the mean proximal neck's (PN) diameter was 24.8±2.7 mm, while the relevant length and angulation were 16.0 mm and 21.7°, respectively. Overall, 22 (53.6%) patients presented with shorter and angulated PN, according to the stent-graft's instructions of use, and in 6 (14.6%) patients the PN angulation &gt;60° was combined with concomitant iliac angulation &gt;60°. Eleven (26.8%) EVARs were performed with concomitant enormous iliac artery narrowing and tortuosity. Finally, in 19 (46.3%) AAAs, the distal iliac landing zone was aneurysmatic and they were treated with the bell-bottom technique in 17 patients and with limb extension to the external iliac artery in two cases. We evaluated technical and clinical success of the index procedures, which was based on the combination of five factors: freedom from EVAR-related mortality, from graft-related endoleak of any type, from migration at any part of graft as well the absence of notable increase AAA's sac maximum diameter and the patency of bifurcated stent-graft and of access vessels.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Primary technical and clinical success of index procedures was 100%. During a median 12-month radiological follow-up the clinical success remained 100%. No type I or III endoleak, stent-graft migration, EVAR-related death, AAA rupture, or graft-related adverse events or reinterventions were documented. Four (9.8%) type II endoleaks were detected with stable AAA sac diameter.

Lower extremity peripheral arterial intervention was performed using the endovascular robotic system, which consisted of a bedside unit and an interventional console. The primary endpoints were technical success, defined as the successful manipulation of the lower extremity peripheral arterial devices using the robotic system, and safety. The secondary endpoints were clinical success, defined as 50% residual stenosis at the completion of the robot-assisted procedure without major adverse cardiac events and radiation exposure.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In total, 5 patients with PAD were enrolled in this study (69.2±6.0 years; 80% men). The novel endovascular robotic system successfully completed the entire procedure of endovascular treatment of lower extremity PAD. Conversion to manual operation, including advancement, retracement, rotation of the guidewires, catheters, sheaths, deployment, and release of the balloons and stent grafts, was not necessary. We achieved the criteria for clinical procedural and technical success in all patients. No deaths, myocardial infarctions, or ruptures occurred in the period up to 30 days after the procedure, and no device-related complications were observed.
