Abstract

BACKGROUND:Temporary placement of a retrievable neck bridging device, allowing parent vessel flow, is an attractive alternative to balloon remodeling for treatment of ruptured intracranial aneurysms. OBJECTIVE:To present, in a single-center study, our initial experience with Cascade (Perflow, Israel) in the treatment of ruptured intracranial aneurysms. METHODS:During a period of 1.5 months, 12 patients with aneurysmal subarachnoid hemorrhage underwent coil embolization in conjunction with Cascade in our center. Retrospective analysis of prospectively collected angiographic and clinical data was conducted to assess the safety and efficacy of the device. RESULTS:Among all treated patients, 41.7% (5/12) were female, the median age was 55 (47-77) years, the median aneurysm dome size was 5.75 mm (3-9.1), and the median neck size was 3.55 mm (2.3-7.9). Complete obliteration (Raymond 1) was achieved in 75% (9/12) of cases, and intentional residual neck (Raymond 2) was left in three cases (25%). None of the patients received any oral or intravenous antiplatelet therapy perioperatively. No thromboembolic complications, device-related spasm, vessel perforation, or coil entanglement were detected in any of the treated patients. CONCLUSIONS:In our initial experience, treatment of wide-neck ruptured intracranial aneurysms with Cascade is safe and effective, without the need for adjuvant antiplatelet therapy. Long-term follow-up data in larger cohorts are needed to confirm these preliminary findings.

摘要

背景: 临时放置可回收的颈部桥接装置,允许母体血管流动,是治疗破裂颅内动脉瘤的球囊重建的一个有吸引力的替代方案。 目的: 在一项单中心研究中,介绍我们使用Cascade (Perflow,以色列) 治疗破裂颅内动脉瘤的初步经验。 方法: 在1.5个月的时间里,12例动脉瘤性蛛网膜下腔出血患者在我们中心接受了弹簧圈栓塞联合级联治疗。对前瞻性收集的血管造影和临床数据进行回顾性分析,以评估该装置的安全性和有效性。 结果: 在所有接受治疗的患者中,41.7% (5/12) 为女性,中位年龄为55 (47-77) 岁,中位动脉瘤圆顶大小为5.75  mm (3-9.1),中位颈部大小为3.55  mm (2.3-7.9)。75% (9/12) 的病例达到完全闭塞 (Raymond 1),3例 (25%) 留下有意残留颈部 (Raymond 2)。所有患者围手术期均未接受任何口服或静脉抗血小板治疗。在任何治疗的患者中均未检测到血栓栓塞并发症、装置相关痉挛、血管穿孔或线圈缠绕。 结论: 根据我们的初步经验,采用级联疗法治疗颅内宽颈破裂动脉瘤是安全有效的,不需要辅助抗血小板治疗。需要更大队列的长期随访数据来证实这些初步发现。

METHODS:BACKGROUND:Due to recent advances in endograft design and percutaneous access, technical success could be increased during endovascular aneurysm repair (EVAR). Beside EVAR, endovascular aneurysm sealing (EVAS) provides an alternative procedure to treat aneurysms. To compare the two methods, additional benchmark criteria should be evaluated: Screening time, dose area product (DAP), procedure time and contrast use. In this study these technical variables are analyzed for EVAS vs. EVAR in comparable patient cohorts. METHODS:It is a retrospective, single-center study. Only elective cases of infrarenal aortic aneurysms were included, all treated by the same surgeon (D.B.). Procedures were performed within the instructions for use without additional procedures. All operations were undertaken in a hybrid operating theatre. For EVAR, only the Medtronic Endurant® and the Gore C3 Excluder® were included. For EVAS the Nellix® from Endologix was used. RESULTS:Between 2012 and 2016, 67 patients were treated with EVAS and 40 with EVAR; of these 20 and 16 could be introduced into the study respectively. Median age was 73 and 72 years respectively (only men). The two groups were comparable in terms of BMI, GFR and ASA-status. Screening time was reduced for EVAS (10.6 vs. 14.5 min., P<0.01), while the DAP was not significantly different. Procedural time and contrast use were increased for EVAS (120 vs. 96 min., 120 vs. 79 mL, P<0.01). CONCLUSIONS:Especially the younger EVAS-procedure requires ongoing review in order to further reduce contrast agent. Reduced screening time for EVAS does not have a significant impact on radiation dose.

METHODS:OBJECTIVE:To evaluate reasons to deviate from aneurysm diameter thresholds, and focus on the difference in how Dutch vascular surgical units (VSUs) perceive their deviation and their actual deviation. BACKGROUND:Guidelines recommend surgical treatment for asymptomatic abdominal aortic aneurysms (AAAs) with a diameter of at least 55 mm for men and 50 mm for women. We evaluate reasons to deviate from these guidelines, and focus on the difference in how Dutch vascular surgical units (VSUs) perceive their deviation and their actual deviation. METHODS:All patients undergoing elective AAA repair between 2013 and 2016 registered in the Dutch Surgical Aneurysm Audit (DSAA) were included. Surgery at diameters of <55 mm for men and <50 mm for women were considered guideline deviations. National deviation and hospital variation in deviation were evaluated over time. Questionnaires were distributed among all Dutch VSUs, inquiring for acceptable reasons for guideline deviation. VSUs were asked to estimate the guideline deviation percentage in their hospital which was then compared with their DSAA percentage. RESULTS:In all, 9039 patients were included. In 15%, we found guideline deviation, varying from 2% to 40% between VSUs. Over time, 21 VSUs were identified with a lower percentage of deviation than the national mean each year and 8 VSUs with a higher percentage. 44/60 VSUs completed the questionnaire. Most commonly reported reasons to deviate were concomitant large iliac diameter (91%) and saccular aneurysm (82%). The majority of the VSUs (77%) estimated their guideline deviation to be <5%. Eleven VSUs (25%) estimated their deviation concordant with their DSAA percentage, but 75% of VSUs underestimated their deviation. CONCLUSIONS:Dutch VSUs regularly deviate from the guidelines regarding aneurysm diameter, with variation between VSUs. Consensus exists amongst VSUs on acceptable reasons for guideline deviations; however, the majority underestimates their actual deviation percentage.

METHODS:BACKGROUND:Spinal cord ischemia (SCI) and paraplegia are complications of surgery for type A acute aortic dissection (TAAAD). Since the segmental arteries play a key role in SCI, this study evaluated the association between SCI and false lumen segmental arteries (FLSAs: segmental arteries originating from the false lumen). METHODS:The study included 101 consecutive TAAAD patients (mean age, 66±13; range, 34-89 years) who underwent surgery from January 2011 to April 2017. The diagnosis of TAAAD and the number of FSLAs were determined by preoperative computed tomography (CT). Patients were divided into two groups according to the number of FLSAs at the Th9-L2 level: Group A (N.=13), ≥8 FLSAs; and group B (N.=88), ≤7 FLSAs. Preoperative, perioperative, and postoperative findings were compared between the groups, and risk factors for SCI were evaluated. RESULTS:The frequency of preoperative paralysis was significantly higher in Group A than Group B (P=.0070). The overall incidence of postoperative SCI was 8% (8/101) and significantly higher in Group A than Group B (5/13 [45%] vs. 3/88 (4%), P<0.0001). Hospital mortality was 8% (8/101) and significantly higher in Group A than Group B (3/13 [23%] vs. 5/88 [6%], P=.0302). Multivariate analysis showed that the independent risk factors for SCI were ≥8 FLSAs at Th9-L2 (odds ratio [OR], 20.4; 95% confidence interval [95% CI], 3.34-124.9, P=0.0011) and diabetes mellitus (OR, 22.3; 95% CI, 1.69-294.5; P=0.0184). CONCLUSIONS:In patients who underwent surgery for TAAAD, ≥8 FLSAs at the Th9-L2 levels on preoperative CT was a risk factor for SCI.
