改良双腔球囊导管在插管失败的输卵管阻塞介入再通术中的应用价值

目的探讨改良双腔球囊导管在插管失败的输卵管阻塞介入再通术中的应用价值。方法回顾45例输卵管阻塞性不孕患者,应用常规法行介入再通术,其中输卵管开口插管失败采用改良双腔球囊导管行介入再通,统计分析常规法组与联合改良双腔球囊导管法组(联合法组)的输卵管开口插管成功率、输卵管阻塞的开通率。结果输卵管阻塞性不孕患者45例,共阻塞输卵管90条,采用常规法输卵管开口插管成功32条,其中开通成功31条,插管成功率为35.56%,开通率96.88%。采用联合法输卵管开口插管成功90条,输卵管开通83条,插管成功率为100%,开通率92.22%,7条输卵管因阻塞病情严重无法开通,其中双侧均未能开通1例。所有患者术中均无严重并发症发生。随访12个月,妊娠率48.65%。常规法组与联合法组输卵管开口插管成功率差异具有统计学意义(χ^2=85.574,P=0.000),而输卵管开通率差异无统计学意义(χ^2=0.248,P=0.619)。结论对于常规法输卵管开口插管失败者,采用联合改良双腔球囊导管可提高输卵管开口插管成功率。采用改良双腔球囊导管介入再通与常规法开通效果相当,可作为常规介入再通输卵管开口插管失败的备选方案。

Concentrating stroke care provision in the Czech Republic: The establishment of Stroke Centres in 2011 has led to improved outcomes

This article describes policy processes that have led to the re-organisation of stroke care in the Czech Republic since 2011, which has been part of a broader process of care concentration in several medical fields. Currently, stroke care is provided by 13 Comprehensive and 32 Primary Stroke Centres. The paper explains factors that supported the reform implementation, reviews implications, and discusses future challenges.Mandatory reporting of quality indicators, the introduction of a benchmarking system, integration with pre-hospital emergency care, and the introduction of countrywide patient triage have supported more timely treatment for stroke patients and better quality of care. Data from the Stroke Care Quality Indicators of the Czech Stroke Society show positive trends in many areas: the number of patients treated with intravenous thrombolysis quadrupled in eight years, with 26.4 % of all acute stroke patients receiving thrombolysis in 2018. Czech Republic now ranks third in Europe in the number of thrombolysis per population and second in the number of mechanical thrombectomies per population. The Czech experience provides an example of positive outcomes of concentrated stroke care, while highlighting the importance of proper implementation processes. In particular, it is essential to involve stakeholders and to provide reputational incentives through continuous benchmarking.     

Application of retrievable Solitaire AB stents in the endovascular treatment of acute ischemic stroke

Purpose: Retrievable stents are widely used in acute ischemic stroke (AIS); however, the results remain unclear in Chinese patients. This study aimed to explore the usefulness of Solitaire AB stents in AIS.Materials and Methods: Seventy-three AIS patients treated with Solitaire AB stents for thrombectomy of large artery occlusion of anterior circulation in January 2014-June 2015 were retrospectively evaluated. Recanalization was assessed with the Thrombolysis In Cerebral Ischemia (TICI) scale. Clinical outcomes were assessed according to the National Institute of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS). Operation-related complications were recorded. The main factors affecting successful recanalization with Solitaire AB were analyzed.Results: The 73 patients enrolled included 39 males and 34 females (median age of 59 [31-78] years); 77 Solitaire AB stents were used. The initial recanalization rate with Solitaire AB as the first thrombectomy method was 53.42% (39/73; recanalization group). Among the 34 patients with failed stent retrieval, 32 underwent other treatments; the final arterial recanalization rate was 89.04% (65/73). Perioperative embolization events and symptomatic intracranial hemorrhage (sICH) occurred in 5 and 8 patients, respectively. The mean NIHSS score was 9.12±3.86 one week after thrombectomy, significantly lower compared with admission values. In 31 patients (42.47%), NIHSS score decreased by >8. Good functional independence (mRS score≤2) was achieved in 39 patients (53.42%) at 90 days; 12 patients (16.44%) died. Compared with the recanalization group, the remaining patients showed lower AF and higher LAA percentages.Conclusion: Solitaire AB stents are useful in the endovascular treatment of AIS.     

Open surgical embolectomy for cardiogenic cerebral embolism: Technical note and its advantages

Background and importanceIn cardiogenic cerebral embolism, early recanalization is the most important factor for good prognosis. However, endovascular thrombectomy often fails to achieve recanalization. We present an open surgical embolectomy technique and discuss its advantages.Clinical presentationA 79-year-old woman developed right hemiparesis and severe aphasia. Magnetic resonance imaging revealed an acute cerebral infarction caused by left middle cerebral artery (MCA) occlusion. We attempted endovascular thrombectomy but failed because it was impossible to guide the catheter to the occlusion site. Hence, we converted to open surgical embolectomy. Sylvian fissure was widely opened. After confirming the range of thrombosis using indocyanine green videoangiography (ICGVAG), the proximal and distal arteries were secured, and a temporary clip was placed on the distal M2 to prevent distal thrombosis migration. MCA was cut approximately 3 mm from the bifurcation, and thrombosis was removed using micro-forceps. The proximal clip was simultaneously inserted but was not clamped because the thrombus was extruded by proximal vascular flow. Immediately after removing the thrombus, intense bleeding occurred from the proximal flow. An assistant clamped the proximal artery using the prepared clip, and the incised area of MCA was sutured using 9-0 threads. We finally confirmed blood flow after recanalization using ICGVAG. The time from skin incision to recanalization was 27 min. After the procedure, the patient developed slight aphasia but had no hemiparesis and was later transferred to a rehabilitation hospital.ConclusionOpen surgical embolectomy may be a secondary rescue treatment option in the case of endovascular thrombectomy failure.     

Outcome and recanalization rate of tandem basilar artery occlusion treated by mechanical thrombectomy

BackgroundTandem basilar artery occlusions (tBAO) are defined as concomitant basilar artery and extracranial dominant vertebral artery occlusions. The prognosis of such tBAO treated by mechanical thrombectomy (MT) has been scantly reported.The purpose of our study was to compare the safety and effectiveness of MT for patients with tBAO compared to those with non-tandem basilar artery occlusions (ntBAO).Patients and methodsRetrospective analysis of a database of patients who underwent MT at two academic centres. All patients treated for BAO were retrieved. Patients with tBAO, defined as a concomitant BAO and extracranial vertebral artery (VA) occlusion or severe stenosis ≥70% (V1 or proximal V2 segment) were compared with patients with ntBAO.ResultsA total of 15 patients with tBAO and 74 patients with ntBAO were enrolled. Successful reperfusion (modified thrombolysis in cerebral infarction score ≥2b) was obtained in 73.3% versus 90.5% (OR = 0.29, 95%CI: 0.07–1.15), good clinical outcome (3-months modified Rankin scale ≤2) was reached by 26.7% versus 32.4% (OR = 0.76; 95% CI: 0.24–2.63) and mortality at 3-months was 46.7% versus 31% (OR = 1.94; 95%CI: 0.63–6) of patients with tBAO versus ntBAO, respectively. Two patients (13.3%) with tBAO and three (4%) with ntBAO had symptomatic intracranial haemorrhage (OR = 3.64; 95% CI: 0.55–24).ConclusionMechanical thrombectomy for patients with tandem basilar artery occlusion tends to be associated with lower rates of successful reperfusion and good clinical outcome, and higher rate of mortality. Larger multicentre studies are warranted to better precise the proper selection and management of such patients.     

胆道引流管滑脱后窦道闭塞的再通

胆道镜已广泛应用于临床,经窦道胆道镜取石改变了胆道术后残余结石需要行多次手术的弊端,已经成为治疗术后残余结石的理想途径和首选方法[1-3].但是,如不慎致窦道内胆道引流管滑脱,可导致窦道闭塞[4].此时如不能及时再通窦道,则需要进一步行ERCP或手术治疗,很大程度增加了患者的痛苦及医疗费用.2001年7月至2012年5月我院对23例胆道引流管滑脱致窦道闭塞的患者进行了X线监控下导丝引导的气囊扩张窦道再通术,疗效满意.     

Nonsurgical treatment of childhood hypertension: Embolization of an intrarenal aneurysm

Renal artery aneurysms are an unusual cause of renovascular hypertension in children. When present in an intrarenal location, they pose a difficult surgical problem and transcatheter embolization may represent an effective alternative treatment.
