Nevertheless, the existing effective drugs for AAA treatment are limited, necessitating a pressing exploration for novel therapeutic medications.MethodsAAA-related transcriptome data were downloaded from GEO, and differentially expressed genes (DEGs) in AAA tissue were screened for GO and KEGG enrichment analyses. Small molecule compounds and their target proteins with negative connectivity to the AAA expression profile were predicted in the Connectivity Map (CMap) database. Molecular docking and molecular dynamics simulation were performed to predict the binding of the target protein to the small molecule compound, and the MM/GBSA method was used to calculate the binding free energy. Cluster analysis was performed using the cluster tool in the GROMACS package. An AAA cell-free model was built, and CETSA experiments were used to demonstrate the binding ability of small molecules to the target protein in cells.ResultsA total of 2244 DEGs in AAA were obtained through differential analysis, and the DEGs were mainly enriched in the tubulin binding biological function and cell cycle pathway. The CMap results showed that Apicidin had a potential therapeutic effect on AAA with a connectivity score of -97.74, and HDAC4 was the target protein of Apicidin. Based on literature, HDAC4-Apicidin was selected as the subsequent research object. The lowest affinity of Apicidin-HDAC4 molecular docking was -8.218 kcal/mol. Molecular dynamics simulation results indicated that Apicidin-HDAC4 could form a stable complex. MM/GBSA analysis showed a total binding free energy of -55.40 ± 0.79 kcal/mol, and cluster analysis showed that there were two main conformational clusters during the binding process, accounting for 22.4% and 57.8%, respectively. Apicidin could form hydrogen bonds with surrounding residues for stable binding.

Treatment entails placing an endograft across the neck of the saccular aneurysm followed by coiling of the aneurysm through an extraluminal catheter. Debranching procedures of the aortic arch were performed when necessary in order to create a sealing zone of >5 mm. Data collected included demographics, anatomical features of the lesions and sealing zones, indication for intervention, method of treatment and technical success, sac expansion, and reinterventions.Results17 patients (median age 69, 14 males) were treated for saccular aneurysms with short, suboptimal sealing zones (aortic arch 13, distal thoracic aorta 2, celiac trunk 1, brachiocephalic artery 1). Among the aortic arch aneurysms, six required preoperative debranching procedures of the aortic arch in order to create a short landing zone of 5 mm, making them eligible for the procedure. Technical success was obtained in all patients. One perioperative mortality occurred. Mean follow-up among those treated for arch aneurysms was 32 months (range 1-71 months). One patient who was treated for an aortic arch aneurysm had a persistent endoleak. No sac enlargement was observed. None of the patients required interventions and none experienced aneurysm related mortality.ConclusionThe jailed coiling technique is a safe and effective method to treat saccular arterial aneurysms with suboptimal, short sealing zones. It can be utilized for saccular aneurysms located within the aortic arch and for aneurysms located in other locations where coiling or stent grafting is not an option.

While previous studies have established that vascular surgery patients with malnutrition had poorer outcomes, the impact of nutritional status in patients undergoing endovascular aneurysm repair (EVAR) has not yet been investigated. Therefore, this study aimed to assess the effect of malnutrition on 30-day outcomes following non-ruptured EVAR.MethodsPatients who had infrarenal EVAR were identified in the ACS-NSQIP targeted database from 2012-2022. Exclusion criteria included age less than 18 years, ruptured aneurysm, and emergency. Malnutrition was defined as patients with preoperative weight loss of greater than 10% decrease in body weight in the 6 months immediately preceding the surgery. A 1:5 propensity-score matching was used to match demographics, baseline characteristics, aneurysm diameter, distant aneurysm extent, anesthesia, and concomitant procedures between patients with and without malnutrition. Thirty-day postoperative outcomes were examined.ResultsThere were 154 (0.94%) patients with malnutrition who went under non-ruptured EVAR. Meanwhile, 16,309 patients without malnutrition went under intact EVAR, where 737 of them were matched to all malnutrition patients. Malnourished patients had more comorbidity burdens. After propensity-score matching, patients with malnutrition had elevated but non-significant 30-day mortality (5.92% vs 2.99%, <i>p</i> = .09).

Hemodynamics were quantified at the suprarenal aorta (SupAo), bilateral renal arteries (RRA and LRA), and infrarenal aorta (InfAo). Cardiac phase-resolved blood flow values (BFVs), relative flow distribution (RFD), and flow change rates (FCRs) were assessed. Estimated glomerular filtration rate (eGFR) was measured pre- and postoperatively.ResultsA total of 16 patients were analyzed after excluding two outliers. Pre-EVAR BFVs were 23.1 ± 8.3, 3.7 ± 1.3, 3.4 ± 1.2, and 15.1 ± 5.9 mL/cycle, while post-EVAR BFVs were 20.9 ± 6.9, 3.8 ± 1.1, 3.2 ± 0.9, and 12.1 ± 4.3 mL/cycle in SupAo, RRA, LRA, and InfAo, respectively.
