Purpose: To assess periprocedural results and secondary endovascular procedure outcomes over 5 years in patients aged ≥80 vs <80 years undergoing endovascular aneurysm repair (EVAR). Materials and Methods: Data from the Endurant Stent Graft Natural Selection Global post-market registry (ENGAGE) were used for the analyses. A total of 1263 consecutive patients were enrolled in the prospective, observational, single-arm registry and divided into 2 groups according to age: ≥80 years (290, 22.9%) and <80 years (973, 77.1%). Baseline patient characteristics, risk scores according to the Society for Vascular Surgery (SVS) reporting standards, American Society of Anesthesiologists (ASA) classification, quality of life assessments [EuroQol 5 (EQ5D) index], and treatment outcomes, including all-cause mortality, aneurysm-related mortality, major adverse events, secondary endovascular procedures, and endoleaks were compared between groups. Results: Octogenarians were classified into the highest category of the SVS risk stratification system; however, this did not result in a significant difference in the 30-day mortality [1.4% (4/290) vs 1.2% (12/973) for controls; p=0.85] or major adverse event rates [5.2% (15/290) vs 3.6% (35/973), p=0.23]. Multivariable analysis confirmed that age ≥80 years, pulmonary disease, large aneurysm diameter, and renal insufficiency were significantly associated with all-cause mortality, whereas diameter was the only parameter associated with increased aneurysm-related mortality. The differences in freedom from secondary endovascular procedures over 5 years between octogenarians and controls did not reach statistical significance (88.5% vs 83.2%, p=0.07). Conclusion: EVAR can be performed in individuals aged ≥80 years with no statistically significant difference in midterm aneurysm-related deaths compared with younger patients. The findings in this elderly patient cohort show that EVAR can be safely performed with acceptable morbidity rates in octogenarians.
Infrarenal abdominal aortic dissections (IAAD) are exceedingly rare, accounting for 1-4% of all aortic dissections. The evidence is scarce on how to best manage IAAD when they become symptomatic. Two main interventional approaches exist, open surgery and the endovascular approach. Conventional stent-graft systems make it difficult to treat nonaneurysmal aortic disease due to limb competition in a narrow distal aorta. Thus, we present a novel use of the Endologix Anatomical Fixation 2 (AFX2) Abdominal Aortic Aneurysm (AAA) endograft system for the treatment of four patients with IAAD. We also highlight an individual case study that was treated with an alternative endovascular approach and the complications that followed. This was to highlight and compare our successful experience with Endologix AFX2 AAA endograft system. There were multiple benefits for choosing this stent-graft; however the main advantage is its suitability in the narrow distal aorta. Our aim was to highlight an alternative endovascular approach for the successful treatment of a rare, challenging, and potentially fatal pathology.
Central venous catheter (CVC) insertion with ultrasound guidance is routine clinical practice in the critically ill patient. Arterial malposition is serious and may lead to severe complications such as hemorrhage, stroke, or death. We describe a bail-out technique for removal of right-sided CVC that was mispositioned into the brachiocephalic trunk (BCT) at the origin of the right common carotid artery (CCA). Covered stenting of the BCT extending into the CCA in combination with plug embolization of the right subclavian artery was utilized.
A 55-year-old man of Indian descent, presented to the emergency department with a 2-year history of passing 'milky' white urine, associated with dysuria, urinary retention, bilateral flank pain and 15 kg weight loss. He had migrated to Australia from India at the age of 16, with no overseas travel since, and denied having any fevers, rigours or chills. He was found to have chyluria and nephrotic-range proteinuria with marked hypoalbuminaemia and hypogammaglobulinaemia. Due to his ethnic origin and by diagnostic exclusion, a presumptive diagnosis of filariasis was made. With bilateral lymphorenal disconnection, as definitive management, the patient's chyluria and proteinuria resolved with restoration of normal plasma protein and immunoglobulin levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
