Summary: The study on outcomes after endovascular abdominal aortic aneurysm repair (EVAR) stent graft explantation in various Canadian centers showed an increasing trend in Canada. Patients undergoing elective explantation for endoleak had lower mortality compared to those treated for infection or rupture. Patients with an indication for explantation should be offered surgery before symptoms or rupture has occurred.

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.

Summary: The study aimed to investigate the impact of long-term anticoagulation therapy on endoleak development and sac regression in patients undergoing EVAR, revealing a potential association between long-term anticoagulation and persistent type II endoleaks, as well as a lack of aortic sac reduction without an increased risk for subsequent reintervention.

Summary: The study compared two surgical strategies (EXP and F-EVAR) for treating type IA endoleak after EVAR. Results showed lower major adverse events at 30 days in the F-EVAR group compared to the EXP group, with similar one-year survival rates. F-EVAR was associated with decreased early morbidity.

Summary: This study aimed to investigate the long-term use of Endologix AFX endografts and found a high rate of type III endoleaks in early generation devices, with a freedom rate of less than 50% at 8-year follow-up. Most of these endoleaks were not detected until several years after initial implantation, highlighting the importance of long-term imaging surveillance and timely intervention.

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: The study suggests that a higher D-dimer level at 1 year may predict aneurysm enlargement within 5 years in patients with persistent type 2 endoleak. On the other hand, aneurysm expansion is unlikely if the D-dimer level is low enough.

Summary: This retrospective case-control study aimed to determine the effect of persisting type 2 endoleaks (pEL2) on the evolution of abdominal aortic aneurysm (AAA) diameter after endovascular abdominal aortic aneurysm repair (EVAR). The results showed that pEL2 were associated with AAA expansion.

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: Little evidence exists supporting the optimal treatment of type II endoleaks associated with aortic sac growth. This study compared the effectiveness of Onyx embolization and coil embolization for treating type II endoleaks. The results suggest that patients treated with Onyx were less likely to require further reinterventions compared to those treated with coil embolization.

Summary: This study aimed to evaluate the occurrence of Type III endoleaks (T3ELs) in complex endovascular aneurysm repair (c-EVAR) and determine their impact on clinical outcomes. The results showed that T3ELs are relatively rare in c-EVAR and are usually identified during the index hospitalization. The development of T3ELs is associated with higher device modularity and modification.

Summary: Fenestrated and branched stent grafts are commonly used for endovascular repair of complex aortic aneurysms. This case report describes a technique of partial graft explantation for treating a recalcitrant type II endoleak, which avoids the need for visceral branch reimplantation.

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: This study compared the efficacy and safety of direct sac puncture (DSP) and transarterial embolization for type 2 endoleaks (T2ELs). The results showed that DSP had a higher success rate and was more effective in achieving aneurysm sac stability and resolution of endoleak compared to transarterial embolization.

Summary: This study evaluated the efficacy of preemptive embolization of aneurysm side branches in preventing type 2 endoleak (T2EL). The results showed that preemptive embolization resulted in better anatomical changes in the aneurysm sac and a lower T2EL-related intervention rate up to 2 years after EVAR.
