Summary: This study based on the Japanese Committee for Stentgraft Management registry reveals a correlation between persistent type II endoleak (p-T2EL) and late adverse events, including aneurysm sac enlargement, reintervention, rupture, and abdominal aortic aneurysm-related mortality following endovascular aneurysm repair. Apart from p-T2EL, older age, female sex, chronic kidney disease, and dilated proximal neck were associated with sac enlargement.

Summary: This study investigated the impact of the number of patent lumbar arteries (LAs) on sac enlargement after endovascular aneurysm repair (EVAR). The results showed that when the inferior mesenteric artery (IMA) was patent pre-operatively, a high number of patent LAs significantly promoted sac enlargement with type II endoleak (T2EL). However, when the IMA was occluded pre-operatively, a high number of patent LAs had limited influence on sac enlargement.

Summary: This study investigated the incidence and complexity of type II endoleaks after F/B-EVAR. The results showed that nearly half of the patients experienced endoleaks, with the majority being type II and nearly a fifth associated with sac expansion. Treatment of type II endoleaks often led to increased complexity, with the presence of significant type I or III endoleaks. Further research is needed to determine the treatment goal for complex aneurysm repair and the management of type II endoleaks.

Summary: This study investigated the evolution of the shortest apposition length (SAL) post-EVAR and found that a declining SAL during follow-up may be an indicator for the development of late type 1a endoleaks (T1aELs). It is important to include apposition analysis during follow-up as SAL < 10mm is an indicator for T1aEL.

Summary: This study compared the long-term survival of patients with stable aneurysm sacs and those with sac regression after endovascular aneurysm repair (EVAR) and identified independent risk factors for sac regression and mortality after EVAR. The results showed that a stable aneurysm sac after EVAR was associated with increased mortality. Age, ischemic heart disease, neck thrombus, and a type II endoleak were independent risk factors for a stable aneurysm sac.

Summary: This study assessed the association of thrombus burden (TB) with persistent type II endoleaks after infrarenal endovascular aneurysm repair (EVAR). The results showed that low TB was associated with increased rates of persistent type II endoleak, while high TB was associated with increased sac regression and reduced reintervention rates. TB could be used for risk stratification in the planning of infrarenal EVAR and designing a post-EVAR surveillance regimen.

Summary: Late endoleaks were more common in patients treated with anticoagulation after EVAR. No difference in late endoleak frequency was detected between anticoagulation with warfarin and novel oral anticoagulants. Patients on anticoagulation and those with an index endoleak were at a higher risk of having a late endoleak.

Summary: Significant sac regression during early surveillance is crucial for predicting long-term surveillance after endovascular aneurysm repair. Persistent endoleaks are associated with worse outcomes. This study evaluated the differences between different stent grafts regarding sac regression and the presence of type II endoleaks, and how these differences may affect patient categorization for surveillance.

Summary: This study aimed to investigate the mid-term outcomes of embolization procedures for type II endoleak after endovascular abdominal aortic repair and identify the risk factors for aneurysm enlargement. The results showed that embolization procedures were generally ineffective in preventing further expansion of abdominal aortic aneurysms in patients with type II endoleaks, especially in those with a large abdominal aortic aneurysm and/or a presence of a Moyamoya endoleak.

Summary: This study evaluated the incidence and long-term outcomes of postoperative Type 1a endoleak (PT1a) following endovascular aortic aneurysm repair (EVAR). The study found that PT1a incidence was 8.2% with an average onset time of 52 months. Patients who developed PT1a were more likely to be female and had higher mortality rates. Patients with successful intervention for PT1a showed no significant difference in median survival.

Summary: Although surgical outcomes of total arch replacement (TAR) have improved over the last decades, advanced age and severely reduced cardiac function present challenges for conventional TAR. Endovascular and hybrid treatments have shown lower mortality and morbidity rates for patients with extended aortic aneurysms, but can be challenging for patients with slightly dilated ascending aortas.

Summary: The study found that there was no significant impact of endovascular repair (ER) on chronic renal decline (CRD) compared to open repair (OR) up to 4 years after surgery. However, CRD was more common in the ER group during follow-ups exceeding 4 years. Analysis also showed no significant differences in CRD between different fixation groups and the OR group.

Summary: The study revealed that two-thirds of CLTI patients had asymptomatic contralateral limbs, with about half of them experiencing severe ischemia. Older age, dialysis-dependent renal failure, WIfI I-3 in the index limb, and loss of pressure sensation in the contralateral limb were independently associated with severe ischemia in asymptomatic contralateral limbs. Major adverse limb events commonly occurred in these asymptomatic contralateral limbs, particularly those with WIfI I-2/3.

Summary: This study found that the functions of endothelium-derived nitric oxide and hyperpolarizing factor were reduced but partly maintained in autogenous carotid artery grafts under poor runoff conditions. Unlike vein grafts, these artery grafts did not exhibit intimal hyperplasia caused by surgical operation, potentially explaining the improved patency of artery grafts compared with vein grafts.

Summary: This study examined the ambulatory status over time after revascularization and predictors of ambulation loss in CLTI patients. The results found that mobility in the overall population gradually decreased, while the number of deceased patients increased. Factors such as advanced age, impaired mobility before CLTI onset and at revascularization, renal failure on dialysis, and WIfI stage 4 were associated with ambulation loss at almost all points after revascularization.

Summary: This study reviewed patients with persistent type 2 endoleaks (T2ELs) after endovascular aortic aneurysm repair (EVAR) to identify factors associated with spontaneous sac shrinkage (SpS) within 5 years. The results showed that patients with fewer patent lumbar arteries were more likely to experience SpS, even in the presence of persistent T2ELs. Therefore, earlier follow-up imaging studies are advisable even after SpS.
