Abdominal aortic aneurysm repair by endovascular techniques have gained wide acceptance as a treatment option. A potential well-known complication of endovascular repair includes endoleak. Specifically, type II endoleak, which is described as retrograde flow into the aneurysm sac through collateral vessels, can occur in up to 30% of patients. Certain preoperative factors can predict which patients may develop type II endoleak. This article describes laparoscopic inferior mesenteric artery ligation prior to endovascular abdominal aortic aneurysm repair as a viable treatment option in the prevention of type II endoleak.

Thoracic endovascular aortic repair (TEVAR) is widespread. We report a case of graft migration and dissecting aneurysm rupture after trauma. An 82-year-old man with a history of TEVARs for chronic type B aortic dissection had sudden dyspnea and hemoptysis after falling from a stationary bicycle.

Background: Endovascular abdominal aneurysm repair (EVAR) offers a less invasive approach to treating abdominal aortic aneurysms (AAA) compared to open repair. However, EVAR is associated with higher rates of reintervention. This study investigates the early and mid-term outcomes of patients who underwent late open conversion including aneurysmorrhaphy after EVAR at our institution.

Article Synopsis
- The study evaluates the safety and effectiveness of the Zenith Dissection Endovascular System (ZDES) against traditional stent grafts for repairing acute complicated Type B Aortic Dissection (AcTBAD).
- A retrospective analysis of 32 patients revealed that the ZDES group experienced fewer postoperative adverse events (12 vs. 37), demonstrating better outcomes in false lumen thrombosis at 6 months and lower 3-year mortality rates.
- Despite some patients needing secondary interventions in the ZDES cohort due to aortic growth, overall results suggest the ZDES may offer improved safety and efficacy compared to traditional methods.

In the past 15 years, fenestrated-branched endovascular aortic repair (F-BEVAR) has progressively become the first-line option for management of most complex abdominal aortic aneurysms (AAAs); with increasing experience, as well as persistent technological refinements, F-BEVAR indications have been expanded to include rescue of failures after prior EVAR. Despite the feasibility and effectiveness, F-BEVAR procedures in the presence of prior infrarenal endografts may come with higher technical complexity that should be properly anticipated, and several anatomical challenges can be expected. Among these, presence of suprarenal bare stents from prior EVAR device are certainly a frequent scenario and may sometimes make target vessel cannulation more difficult because of encroachment on the target vessel origins.

Objectives: Embolizing an abdominal aortic aneurysm sac through a transcaval approach is a novel approach to treat type-II endoleaks that occur following aortic endografting. This study reviews the outcomes of this treatment in one of the few centres in Australia that offers this procedure.
Methods: A retrospective cohort study was conducted, including patients who had received transcaval embolisation of type-II endoleak over a 9-year period.
