A ruptured splenic artery aneurysm treated by transcatheter arterial embolization using n-butyl cyanoacrylate-Lipiodol-Iopamidol.

ABSTRACT: N-butyl cyanoacrylate, one of embolic materials, is usually used as a mixture with Lipiodol (N-butyl cyanoacrylate-Lipiodol mixture). N-butyl cyanoacrylate-Lipiodol-Iopamidol was developed by adding a nonionic iodine contrast agent (Iopamiron) to N-butyl cyanoacrylate-Lipiodol mixture. N-butyl cyanoacrylate-Lipiodol-Iopamidol has lower adhesiveness than N-butyl cyanoacrylate-Lipiodol mixture and the ability to form a single large droplet. We report the case of a 63-year-old man with a ruptured splenic artery aneurysm treated by transcatheter arterial embolization using N-butyl cyanoacrylate-Lipiodol-Iopamidol. He was referred to the emergency room because of sudden onset of upper abdominal pain. A diagnosis was established using contrast-enhanced computed tomography and angiography. Emergency transcatheter arterial embolization was performed, and the ruptured splenic artery aneurysm was successfully embolized using a combination of coil framing and N-butyl cyanoacrylate-Lipiodol-Iopamidol packing. This case demonstrates the usefulness of a combination of coil framing and N-butyl cyanoacrylate-Lipiodol-Iopamdol packing for the embolization of aneurysms.

Project description:Background Aneurysmal rupture in the aortoiliac segment is a severe, life-threatening condition. Nowadays, in addition to surgical treatment, the implantation of a covered stent graft constitutes a feasible, minimally invasive treatment option. A novel approach is the add-on of transarterial aneurysm sac embolization with N-butyl-cyanoacrylate (NBCA). Here, we report our experience of performing this add-on embolization procedure after endovascular aneurysm repair for complex ruptured aneurysms of the aortoiliac segment. Material and Methods We describe six patients (mean age of 75.2 years; all male) with ruptured aneurysms in the visceral aortic and aortoiliac segment in whom a high-volume transarterial aneurysm sac embolization was performed as an add-on therapy to the implantation of an aortic prosthesis. The aim of this add-on intervention was to achieve the definite embolization of the aneurysmal rupture site and to ensure the best possible aneurysmal sealing. We report the feasibility, technical success, and considerations of using NBCA as well as clinical and follow-up imaging results, given their availability. Results Technical success was achieved in all cases. Clinical success was achieved in four cases. No periprocedural complications or reinterventions were reported. The mean full procedure time was 107.8 min. The mean radiation dose was 12,966.1 cGy/cm2. A mean amount of 10.7 mL of NBCA mixed with lipiodol in a 1:3 to 1:5 ratio was used for all patients. Available follow-up imaging up to 36 months after the procedure showed no aneurysm progression or endoleaks. In two patients, the NBCA cast had almost fully dissolved over the course of follow-up. Conclusions Our study underscores the notion that aneurysm sac embolization using high volumes of NBCA with ethiodized oil as an embolic agent is a feasible and add-on treatment option for optimizing the exclusion of the aneurysm from patients with ruptured aneurysms in the aortoiliac segment.

Project description:ObjectiveComplications in neuroendovascular therapy for cerebral aneurysm (AN) affect the clinical course of patients. Patient conditions, operating procedures, and operator expertise were highlighted as risk factors for complications. These risk factors often combine and constitute particularly strong risks, resulting in a worsened clinical course. In this study, we performed a multifactorial assessment of complication risks in neuroendovascular therapy.MethodsWe analyzed patient data from the Japanese Registry of NeuroEndovascular Therapy 3, which is a nationwide retrospective cohort study of neuroendovascular procedures conducted between 2010 and 2014. Patients who underwent coil embolization for a ruptured anterior communicating artery (Acom) AN, an internal carotid artery-posterior communicating artery (IC-PC) AN, or basilar artery bifurcation (BA-bif) AN were included in this analysis. Information on 16 explanatory variables and 1 objective variable for each patient was obtained from the dataset as nominal variables. The explanatory variables consisted of patient factors, procedural factors, and an operator factor. The objective variable was whether the following complications occurred: intraprocedural bleeding, postprocedural bleeding, and procedure-related infarction. The specific situations involving multiple risk factors associated with high complication rates were identified using a programmed method. The impact of the absence of a supervising physician was also assessed.ResultsA total of 2971 patients were analyzed. The complication rates for patients with Acom ANs, IC-PC ANs, and BA-bif ANs were 12.9%, 10.2%, and 13.7%, respectively. A total of 15 specific situations were identified as follows: 3 related to an Acom AN, with complication rates ranging from 19.3% to 20.3%; 4 related to an IC-PC AN, with complication rates ranging from 15.6% to 17.9%; and 8 related to a BA-bif AN, with complication rates ranging from 20.6% to 33.3%. In 4 of these situations, the absence of a supervising physician significantly impacted complication rates. For instance, the complication rate for patients with IC-PC AN treated under local anesthesia was 16.0% overall, but it was 23.8% without supervising physicians.ConclusionMultifactorial assessment based on patient, procedural, and operator factors provides more reliable risk estimations and will help improve the clinical course.
