Objective: Endovascular aortic repair (EVAR) for elective and emergency infrarenal aortic pathologies is the primary approach for treatment nowadays. During such procedure, the suture-mediated closure device (SMCD) (Perclose ProGlide^TM, Abbott Laboratories, Chicago, IL, USA) is commonly used. This study aimed to identify potential contributors for SMCD failure in a patient cohort of elective and emergency EVAR.

Methods: Archived medical records from patients who underwent EVAR for aortic pathologies in elective and emergency setting at the University Hospital Düsseldorf, Germany were included. Patient's co-morbidities, access vessel morphologies and hemostasis-related blood parameters were evaluated on their association with SMCD failure applying different statistical methods.

Results: A total of 71 patients (139 femoral accesses) was included. The mean age was 73.5 ± 8.4 years. Overall SMCD failure rate was 4.3%, 4.1% for elective and 5.9% for emergency cases, respectively. Total procedure time was longer for the SMCD failure group (323 ± 117.8 min vs 171 ± 43.7 min). The calcification status of the common femoral artery (CFA), the diameter of the aortic bifurcation, and dual anti-platelet therapy (DAPT) on the medication plan prior to the procedure were associated with SMCD failure. Univariate binary logistic regression analysis nominated several potentially relevant predictors for SMCD failure who underwent subsequent multivariable binary logistic regression analysis. Here, DAPT on the medication plan was identified as being promising in predicting SMCD failure (OR 30.5), while anterior plaque formation in the CFA maintained as only statistically relevant determinant (OR 44.9).

Conclusions: This study confirms the CFA calcification status to be associated with SMCD failure. Although discontinued prior to endovascular treatment, DAPT was also found to be associated with SMCD failure. Our results may advocate to perform obligatory platelet testing prior to EVAR to maximize patient safety.

Aim: The impact of technical differences in cannulation technique for tunnelled haemodialysis catheter insertion is undetermined. We aimed to assess clinical outcomes of the low posterior approach for internal jugular vein tunnelled catheter placement.

Methods: A retrospective audit was undertaken on consecutive tunnelled catheter procedures performed at a single centre between January 2016 and June 2022. Only catheters specifically placed with a low posterior internal jugular approach were included. The study's primary outcome was 12-month catheter survival, evaluated using the Kaplan-Meier survival curve and log-rank test. Secondary outcomes included catheter performance and procedure-related complications.

Results: During the study period, 391 tunnelled internal jugular haemodialysis catheters were inserted in 272 patients using the low posterior technique. The 12-month primary patency rate was 68%. Catheter insertion was successful in 96% of cases. Peri-procedural complications occurred in 4% of cases, most frequently bleeding. The most common reasons for catheter loss were dysfunction (10%) and bacteraemia (6%). The best predictors of catheter failure were advanced age (HR 1.02, 95% CI 1.00-1.04) and in-centre dialysis treatment locality (HR 2.04, 95% CI 1.19-3.45).

Conclusion: The low posterior approach for internal jugular vein tunnelled catheter insertion is effective and safe. We demonstrated a 12-month catheter survival rate of 68%. Further research comparing the low posterior approach with other internal jugular vein cannulation techniques is warranted.

Background: Aortic aneurysms represent a chronic degenerative disease with life-threatening implications. In order for patients to comprehend health related information, it must be written at a level that can be readily understood.

Study design: In January 2023, we searched "aneurisma aorta" and "endoprótesis aorta" terms on Google, Yahoo and Microsoft/Bing. The 31th websites provided by each search engine were analyzed. Four readability measures were used to evaluate websites regarding aortic aneurysm and their endovascular treatment in Spanish language: Flesch Index, Flesch-Szigriszt Index, Fernández-Huerta Index and grading Inflesz scale. The quality on information was evaluated by the HONcode seal, the DISCERN instrument and the JAMA benchmark criteria.

Results: 180 websites containing the terms "aneurisma aorta" and "endoprótesis aorta" were analyzed. Among the websites retrieved, the mean Flesh index score (53.12 ± 6.09 and 47.48 ± 7.12, respectively; P = .019), the Flesch-Szigriszt index (56.39 ± 5.72 and 48.10 ± 8.33; P = .000), and the Fernández Huerta index (61.30 ± 5.59 and 53.19 ± 8.21; P = .000), corresponding to a "somewhat difficult" readability level. In addition, the Inflesz scale (2.62 ± .59 and 2.07 ± .61; P = .000) reported a "somewhat difficult" readability, higher for the websites regarding aortic aneurysm. The HONcode seal was only presented in websites regarding aortic aneurysm (16.7%), whereas none of the websites relating to aortic endoprostheses presented it (0%) (P = .000). Websites that presented the HONcode seal obtained higher DISCERN score (P = .000, 95% CI = 6.42-16.84) and JAMA score (P = .000, 95% CI = 3.44-11.32).

Conclusion: Internet information on aortic aneurysms and aortic endoprostheses is too difficult to read for the general Spanish-speaking population and is lacking in quality.

41-year-old lady, known case of Takayasu arteritis with pulmonary arterial involvement, presented with multiple episodes of haemoptysis (maximum 50 mL) in a week. She had undergone descending thoracic aorta angioplasty and stenting 3 years ago due to uncontrolled hypertension, left ventricular systolic dysfunction and approximately 70% stenosis of descending thoracic aorta. This lady was treated with embolization of hypertrophied bronchial artery as well as left internal mammary artery branch for management of haemoptysis. Embolization of hypertrophied bronchial artery in the setting of Takayasu arteritis with pulmonary arterial involvement presenting with haemoptysis is rare. Hypertrophied bronchial artery detected in post stenting computed tomography raises suspicion whether descending thoracic aorta stenting promotes the hypertrophy of bronchial artery. Literature of bronchial artery embolization in the setting of Takayasu with post DTA stenting is scarce.
