As a blood flow control technique for embolization using glue (n-butyl cyanoacrylate; NBCA) for peripheral artery aneurysm/pseudoaneurysm, we placed a vascular plug or coils at the proximal inflow vessel before glue injection. We describe this maneuver, which we call the glue in lockdown technique. Four peripheral aneurysms-two pulmonary artery pseudoaneurysms, one pancreaticoduodenal arcade pseudoaneurysm, and one internal iliac artery aneurysm-deemed unsuitable for conventional embolization because of abnormal blood flow, coagulopathy, or anatomical complexity were embolized with our technique.

Objectives: We assessed the diagnostic advantage of dual-energy computed tomography (DECT) over single-energy computed tomography (SECT) to evaluate lipiodol accumulation in target lesions following transcatheter arterial chemoembolization (TACE).

Methods: TACE was performed in 10 rabbits in whom the VX2 tumor was implanted in their left liver lobes. The miriplatin-lipiodol mixture was injected into the common hepatic artery.

Background: Spontaneous isolated visceral artery dissection (SIVAD) is rare. Recently, appropriate treatment strategies for symptomatic SIVAD have been proposed. We aimed to determine the management of asymptomatic spontaneous isolated superior mesenteric artery dissection (ASISMAD), which is relatively frequently encountered in SIVAD.

Article Synopsis
  • - This study aimed to compare the safety and effectiveness of two embolization methods (nBCA-ethiodized oil [NE] and nBCA-ethiodized oil-ethanol [NEE]) for treating Type II endoleak (T2EL) after endovascular aortic repair, involving 24 patients across 49 procedures.
  • - Follow-up revealed that while both methods had no serious adverse events, the NEE group had better outcomes, showing 87.5% freedom from sac enlargement and 100% freedom from reintervention at 1 year, compared to 65.0% and 69.2% in the NE group, respectively.
  • - The findings suggest that the N

Article Synopsis
  • The study investigates whether preemptive embolization of side branch arteries from the abdominal aortic aneurysm sac can lead to early shrinkage of the aneurysm after endovascular repair.
  • Results showed that the embolization group had a significantly higher occlusion rate of side branch arteries and a lower frequency of type 2 endoleaks compared to the nonembolization group over a 24-month follow-up.
  • Additionally, patients in the embolization group were more likely to experience a reduction in aneurysm sac diameter of over 5 mm, suggesting that preemptive embolization may be beneficial for aneurysm treatment.
