RESUMO
BACKGROUND: The aim of the present study was to evaluate the efficacy of preemptive embolization of aneurysm side branches that cause type 2 endoleak (T2EL). METHODS: We performed a retrospective review of consecutive patients who underwent endovascular aneurysm repair (EVAR) in our facility between April 2009 and April 2019. All the patients underwent the preemptive embolization for preventing T2EL since April 2014. The patients were divided into the nonembolization group (between April 2009 and May 2014) or the embolization group (between April 2014 and April 2019). We used a support wire to improve a success rate of the preemptive embolization. The aneurysm sac shrinkage (â§5 mm), freedom from all-cause death and aneurysm-related death, T2EL-related reinterventions, aneurysm sac enlargement (â§5 mm), and complications related to the endovascular procedure were compared between the 2 groups. RESULTS: Two-hundred patients with abdominal aortic aneurysm were included. They were divided into the nonembolization group (N = 103) and the embolization group (N = 97). We successfully embolized 89% of all the patent aneurysm side branches in the embolization group. The characteristics of the 2 groups were similar except for hypertension, patent lumbar arteries, and the use of Zenith, Excluder, and Endurant. The preemptive embolization group showed better aneurysm sac shrinkage (73% vs. 42%; P < 0.0001), no aneurysm sac enlargement (0% vs. 5%; P < 0.05), and lower T2EL-related reintervention rate (hazard ratio, 0.11; 95% confidence interval, 0.0061-0.60; P < 0.01) up to 2 years after EVAR. There were no significant differences in freedom from all-cause death, aneurysm-related death, and complications between the 2 groups. CONCLUSIONS: The present study showed the high success rate of preemptive embolization of aneurysm side branches resulting in better anatomical changes in the aneurysm sac and lower T2EL-related intervention rate in the embolization group up to 2 years after EVAR.

We report a case of an 84-year-old Japanese female patient with transcatheter valve embolization treated with thoracic endovascular stenting. She was diagnosed with severe aortic stenosis and referred to our hospital. Transapical transcatheter aortic valve implantation (TA-TAVI) was selected because she had multiple comorbidities and peripheral vascular disease. During TA-TAVI, the transcatheter valve (TV) came loose and lodged in the distal aortic arch. The TV was floating and unstable, thereby affecting her hemodynamics. After a second TV was placed in the appropriate position with no trouble, we tried fixing the TV using a thoracic endovascular stent-graft. The procedure was successful, and the patient recovered well. The cause of embolization seemed to be associated with a relatively mild calcification of the native aortic valve. Although this complication is rare, several recovery procedures should be prepared.

PURPOSE: Mortality in patients with ruptured abdominal aortic aneurysms (rAAAs) has remained high despite advances in interventions. Endovascular aneurysm repair (EVAR) was recently developed for treatment of rAAAs. In this study, we assessed our endovascular strategy including a double-balloon technique for rAAA. METHODS: We analyzed 12 consecutive patients with rAAAs who were treated by our double-balloon technique and endovascular strategy from March 2013 to July 2016. RESULTS: The 30-day and 1-year mortality rates were both 17%. The mean times from admission to arrival at the hybrid operating room, from admission to aortic occlusion, and from admission to completion of EVAR were 46.8, 63.5, and 110.0 minutes, respectively. CONCLUSION: This study indicates that the herein-described double-balloon endovascular technique is feasible for use in the management of rAAA.

We report a 59-year-old man with intravascular large B-cell lymphoma (IVLBCL) associated with hemophagocytic syndrome, disseminated intravascular coagulopathy, and lung involvement. G-banding analysis of the metaphase spreads obtained from the bone marrow showed that the lymphoma cells were near-tetraploid and included two homologues of the 14q+ chromosome. Spectral karyotyping revealed that complex translocations occurred among chromosomes 3, 12, 14, and 19, and additional materials of 14q+ were from chromosome 19 with the breakpoint at 14q32 and 19q13. To the best of our knowledge, this is the first report describing t(14;19)(q32;q13) in IVLBCL.
