Background: AIOD (Aorto-Iliac Occlusive Disease) may affect any of the arteries from the distal aorta to the common femoral arteries. CERAB (Covered Endovascular Reconstruction of Aortic Bifurcation) is a minimally invasive method used to treat significant and/or recurring aortoiliac occlusive disease. Bare-Metal stents are both effective and safe for treating AIOD. Bare-Metal stents had a statistically substantial greater risk of primary patency in both the general cohort and more complicated TASC C/D lesions.

Background: Hemodialysis (HD) seems to be the most often used Renal Replacement Therapy (RRT) modality worldwide, and it is the primary modality in the majority of instances with extended RRT. The ability to provide our patients with high-quality HD treatment while also increasing their chances of survival is heavily reliant on the functionality of the vascular access (VA). Despite the fact that it is a very necessary component of all clinical practise standards, it is the most expensive individual component of RRT.Objectives: This study was aimed at comparing between the group with Angio access failure and group without Angio access failure and predicting Angio access failure among end stage renal failure patients in Southern Egypt.Subjects and Methods: a prospective cohort study among 125 patients with end stage renal failure at Aswan University. The research comprised patients who had NCVA placement [intra-atrial catheter (IAC) and trans-lumbar catheter (TLC)] between January 1, 2020, and December 31, 2020. Results:The duration of previous RRT was significantly higher among the Angio access failure than the group without Angio access failure. In multivariate analysis using logistic regression, the age, duration of previous RRT, diabetes, IHD (ischemic heart disease), PVD (peripheral vascular disease) and CVD (cardiac vascular disease) were significantly direct predictors of the Angio access failure in the first one year. Conclusion:In conclusion the failure of Angio access was positively associated with age, previous RRT and other comorbidities.
