Risk Factor Analysis of Recanalization Timing in Coiled Aneurysms: Early versus Late Recanalization

BACKGROUND AND PURPOSE:Long-term documentation of anatomic and angiographic characteristics pertaining to the timing of recanalization in coiled aneurysms has been insufficient. Our intent was to analyze and compare early and late-phase recanalization after coiling, identifying respective risk factors.MATERIALS AND METHODS:A total of 870 coiled saccular aneurysms were monitored for extended periods (mean, 30.8 ± 8.3 months). Medical records and radiologic data were also reviewed, stratifying patients as either early (n = 128) or late (n = 52) recanalization or as complete occlusion (n = 690). Early recanalization was equated with confirmed recanalization within 6 months after the procedure, whereas late recanalization was defined as verifiable recanalization after imaging confirmation of complete occlusion at 6 months. A multinomial regression model served to assess potential risk factors, the reference point being early recanalization.RESULTS:Posterior circulation (P = .009), subarachnoid hemorrhage at presentation (P = .011), second attempt for recanalized aneurysm (P < .001), and aneurysm size >7 mm (P < .001) emerged as variables significantly linked with early recanalization (versus complete occlusion). Late (versus early) recanalization corresponded with aneurysms ≤7 mm (P = .013), and in a separate subanalysis of lesions ≤7 mm, aneurysms 4–7 mm showed a significant predilection for late recanalization (P = .008). However, the propensity for complete occlusion in smaller lesions (≤7 mm) increased as the size diminished.CONCLUSIONS:Although long-term complete occlusion after coiling was more likely in aneurysms ≤7 mm, such lesions were more prone to late (versus early) recanalization, particularly those of 4–7 mm in size. Long-term follow-up imaging is thus appropriate in aneurysms >4 mm to detect late recanalization of those formerly demonstrating complete occlusion.

Endovascular coiling is widely used in treating intracranial aneurysms. Despite continued improvement in related techniques and devices, the potential for recanalization remains. Risk factors linked to recanalization have been studied widely through comparative analysis, examining SAH at presentation, larger aneurysms, posterior locations, and other variables.^1,2 Coiled aneurysms showing major recanalization are subsequently in need of additional coiling, given the odds of rebleeding. Raymond et al³ found that 46.9% of all recanalizations occurred within 6 months of procedures, with nearly 40% showing major recanalization.⁴ As a function of the follow-up duration, aneurysm size and neck diameter and initial postembolization status were associated with the recanalization of coiled aneurysms monitored for 17 months.³ However, in coiled aneurysms followed for <17 months, the initial postembolization status emerged as the sole significant risk factor for recanalization. Such a discrepancy may imply that risk factors inherent in aneurysm configuration have a greater long-term impact on recanalization.^4,5 Therefore, an association between the timing of recanalization and related risk factors is feasible. Most previous studies in this setting have limited risk factor analysis to patients showing either recanalization or complete occlusion, without considering time to recanalization. In this study, coiled saccular aneurysms were monitored over a longer term to analyze and compare early and late-phase recanalization, thereby identifying respective risk factors.     

介入性输卵管再通术的护理

Recanalization after endovascular treatment of intracerebral aneurysms

Introduction The aim of this study was to evaluate the risks of endovascular therapy, aneurysm regrowth, recanalization and the need for reembolization. Method A prospective analysis was performed on 211 aneurysms treated endovascularly from February 2000 to December 2003. Of these 211 aneurysms, 81 were asymptomatic and 130 were ruptured. The risks of endovascular therapy, aneurysm regrowth, recanalization and the need for reembolization were evaluated. Results The mean observation time was 10 months (ranging from 178 to 830 days). Complete occlusion (100%) in the initial intervention was achieved in 171 of 201 aneurysms (85%), 80–95% occlusion in 24 aneurysms (12%), and <80% occlusion in 6 aneurysms (3%). Recanalization had occurred at the first follow-up in 34 of all 153 aneurysms reassessed (22.2%). Of 133 aneurysms with initial 100% occlusion, 107 (80.4%) remained completely occluded, 17 (12.7%) showed recanalization, and 9 (6.7%) showed neck regrowth. Among those with 80–95% occlusion, 20 were reassessed, and of these 2 showed spontaneous occlusion, 10 (50%) still showed the initial neck, and 8 (40%) showed increased recanalization. One aneurysm which initially showed <80% occlusion remained unchanged, and another showed showed recanalization. Of the 153 aneurysms, 12 (7.8%) were recoiled, 2 initially <80% occluded, 7 initially 80–95% occluded and 3 initially totally occluded. Conclusion In spite of low morbidity and mortality, one in four aneurysms will show recurrence. The initial degree of occlusion seems to have an influence on the likelihood of recanalization.     

Recanalization results after carotid stent placement

BACKGROUND AND PURPOSE: The details of stent reconstruction in the vascular lumen and of the adaptation of carotid stents, the vessel wall, and the vascular anatomy are only occasionally reported. The purpose of this study was to determine the immediate and longer-term anatomic results after implantation of self-expanding carotid stents. METHODS: In a retrospective study, pre- and postprocedural angiograms and duplex sonograms from 40 consecutive carotid stent procedures in 39 patients (22 men, 17 women; mean age, 67 years; age range, 53-84 years) with high-grade (> or =70 %) internal carotid artery (ICA) stenoses were evaluated to assess the expansion of the vascular lumen, apposition of the stent, and geometric changes in the ICA after the implantation of rolling-membrane and carotid Wallstents (n = 22) or Easy Wallstents (n = 18). RESULTS: Optimal widening of the lumen and apposition of the stent were achieved in 11 (28%) of 40 arteries. Residual stenoses (n = 16), free stent filaments not attached to the vessel wall (n = 21), and stent-induced kinking of the ICA (n = 6) were minor shortcomings of stent reconstruction. Because of one death, peri-interventional morbidity and mortality rates were 3%. During follow-up (median, 24 months), one high-grade restenosis, one ipsilateral stroke, and two ipsilateral transient ischemic attacks were observed. CONCLUSION: Suboptimal anatomic results frequently occur after endovascular treatment of atherosclerotic carotid artery stenosis with self-expanding Wallstents. With the exception of one symptomatic restenosis, no major complications or longer-term sequelae were clearly related to these findings, but further controlled follow-up studies of larger samples are required.     

Radiofrequency Wire Recanalization of Chronically Thrombosed TIPS

Radiofrequency (RF) guide wires have been applied to cardiac interventions, recanalization of central venous thromboses, and to cross biliary occlusions. Herein, the use of a RF wire technique to revise chronically occluded transjugular intrahepatic portosystemic shunts (TIPS) is described. In both cases, conventional TIPS revision techniques failed to revise the chronically thrombosed TIPS. RF wire recanalization was successfully performed through each of the chronically thrombosed TIPS, demonstrating initial safety and feasibility in this application.     

Radiological Recanalization of an Occluded Anterior Resection Anastomosis

We present a case of occluded colorectal anastomosis following surgery for rectal tumor. Contrast enema and antegrade ileography confirmed occlusion by a thin membrane. This was thought amenable to needle puncture and placement of a temporary stent under fluoroscopy guidance, avoiding surgery and its associated morbidity. This provides a minimally invasive alternative to surgery and has only been reported once before.
