Transcatheter fenestration of hemi-Fontan baffles after completion of Fontan physiology using balloon dilatation and stent placement

De novo transcatheter fenestration of hemi-Fontan baffles has not been previously described. The purpose of this report is to present our experience in such de novo transcatheter fenestration in two consecutive patients with absent fenestration in whom the hemi-Fontan baffle was the only direct access to the pulmonary venous atrium.

A new Amplatzer device to maintain patency of Fontan fenestrations and atrial septal defects.

This study evaluated use of Amplatzer fenestrated device to maintain patency of the Fontan fenestration and atrial septal defect. Fenestrations are routinely created in patients with lateral tunnel or extracardiac Fontan. Spontaneous closure of the fenestration can lead to Fontan circulation failure. Other patients without single-ventricle physiology may benefit from a small communication between the left and right atria for decompression if closure of the atrial septal defect leads to failure of a dysfunctional ventricle. Amplatzer septal occluder device was modified to create a fenestration through the disks. Three patients with modified Fontan and one patient with a large atrial septal defect underwent placement of the device by transcatheter technique. The device deployment was guided by transesophageal echocardiography. The procedure was successful in all patients. Contrast injection after placement revealed patent fenestration with free flow. Follow-up ranged from 3 months to 1 year. All devices were patent by transthoracic echocardiography. These preliminary results suggest that the Amplatzer fenestrated device can serve as a valuable tool in failing Fontan circulation and may help to avoid surgical intervention. More studies are needed to assess long-term efficacy of the device.     

颌骨囊肿开窗减压术后戴塞治器疗效分析

目的：追踪下颌囊肿患者囊肿开窗术后应用塞治器,探讨塞治器每日冲洗次数与囊肿恢复快慢的关系。方法：通过对47例下颌囊肿患者开窗术后戴塞治器的复诊记录,根据冲洗次数分成两组：A组为≦2次/日,B组为≧3次/日。根据全景片中囊腔缩小的情况来判断疗效,术后疗效用以下形式记录 显效：囊腔最大径缩小 ≥50% ;好转：囊腔最大径缩小 <50% ;复发：囊腔无明显变化或者增大;愈合归于显效内,有效率以“显效”计算。结果：在A组好转10例,显效8例,复发4例;在B组好转5例,显效18例,复发2例.A组有效率为36.4％,B组为72％,两组有效率差异有统计学意义（χ2=6.01,P=0.02<0．05）。结论：每日冲洗次数与囊肿恢复情况有明显关系,冲洗次数≧3次/日,患者囊肿愈合情况有明显好转。     

Midterm results of laser generated in situ fenestration of the left subclavian artery during thoracic endovascular aneurysm repair

ObjectiveTo analyze the midterm result of in situ fenestration (ISF) of the left subclavian artery (LSA) during thoracic endovascular aneurysm repair (TEVAR).MethodsIn this clinical study, between 2014 and 2016, ISF for LSA revascularization was attempted during TEVAR in 10 patients (7 males; median age, 68 years). An excimer laser, placed from the left brachial artery, was used to create a fenestration and all fenestrations were stented with covered stent grafts. Follow-up included computed tomography scans 1 month postoperatively and annually thereafter. Survival was analyzed according to Kaplan-Meier.ResultsNine of the 10 laser-assisted ISF were successful. No 30-day mortality occurred. One patient had a transient ischemic attacked in the left carotid territory. After a median follow-up of 27 months, all fenestrations were patent. At 1 month, computed tomography follow-up showed nonspecific endoleaks of unknown origin in five of the nine patients. At 27 months follow-up, only two endoleaks remained. One reintervention was done after 24 months owing to a type Ic endoleak from the LSA. Overall TEVAR success, defined as survival with no aneurysm expansion, was eight of nine. One patient showed aneurysm expansion after 14 months. Two deaths occurred (at 33 and 31 months postoperative), one of unknown reason and one aneurysm related.ConclusionsLaser fenestration might be an option for LSA revascularization during emergent or semiurgent TEVAR and electively in patients with hostile neck anatomy (eg, previous neck radiation, short and adipose necks) that might make a carotid–subclavian bypass difficult. The LSA fenestration has excellent patency and TEVAR success was not affected by nonspecific endoleaks around the LSA.     

下颌骨囊肿开窗减压术的回顾分析

目的:探讨保守治疗下颌骨囊肿的方法并评价其疗效。方法:对2000—2006年收治的22例接受保守治疗并随访的下颌骨囊肿病例资料进行综合分析。结果:22例下颌骨囊肿直径为3.5～8.5cm。一期开窗减压术后3～6个月颜面畸形基本消除;术后3、6、12个月X线片复查,囊腔大小分别平均缩小30%、50%、75%;且二期囊肿切除术后6～12个月下颌骨缺损区完全修复。结论:保守治疗较大下颌骨囊肿可以保存下颌骨的连续性及囊肿邻近的重要组织结构;能有效保存牙齿,改善咬合关系;促进新骨生成,减少对下颌骨发育的干扰和手术次数,较快地消除颜面畸形。     

Transcatheter interventions in the early postoperative period after the Fontan procedure

Objective : To analyze the safety and clinical impact of interventional cardiac catheter procedures in the management of early postoperative problems after completion of an extracardiac Fontan procedure. Background : The mortality after Fontan procedure has consistently decreased over the last decade. The role of interventional catheterization to address early postoperative problems in this setting has not been studied systematically. Methods : Over a 9.7‐year period, 289 patients underwent an extracardiac fenestrated Fontan procedure with two early deaths (0.7%) and takedown in four (1.4%). Twenty‐seven patients (9.3%) underwent 32 interventional cardiac catheter procedures at a median interval of 12.2 (1–30) days. The median weight was 14.5 (13.5–25) kg. The case notes and procedure records were reviewed retrospectively. Results : Fontan pathway obstructions were treated in 11 patients with stent implantation with good results and no complications. Stent fenestration of the Fontan circulation was performed in 16 patients with one episode of transient hemiparesis and one episode of pericardial effusion. Three patients underwent initial balloon dilatation of branch pulmonary arteries or fenestration with little effect and underwent stent treatment 6 (5–9) days later. One patient had device closure of a large atrial fenestration. In one patient, residual anterograde pulmonary blood flow was occluded using a device. There were no deaths and in‐hospital course was improved in all. Conclusion : Interventional cardiac catheter procedures can be performed safely and effectively in the early postoperative period after Fontan completion to address hemodynamic problems. These techniques contribute significantly to achieve a very low mortality and address morbidity after Fontan completion. © 2010 Wiley‐Liss, Inc.     

腹股沟斜疝较大疝囊远端囊壁的处置探讨

目的探讨进入阴囊的较大腹股沟斜疝远端囊壁不同的处置方式在术后阴囊并发症上的差异。方法选取240例疝囊进入阴囊的斜疝患者,随机分为两组:旷置组远端疝囊实施旷置+开窗术,剥离组远端疝囊实施完全剥离术。两组患者均采用Lichtenstein手术。比较两组患者在术后阴囊肿胀并发症方面是否存在差异。结果旷置组125例患者术后阴囊肿胀11例(8.80%),其中阴囊水肿8例(6.40%),阴囊积液3例(2.40%),无阴囊血肿和睾丸肿胀。剥离组115例术后阴囊肿胀8例(6.96%),其中阴囊水肿5例(4.35%),阴囊血肿1例(0.87%),阴囊积液1例(0.87%),睾丸肿胀1例(0.87%)。比较两组术后阴囊肿胀发生情况,(P0.05),两组之间差异没有明显统计学意义。结论远端疝囊旷置+开窗手术,术后阴囊肿胀发生率与剥离组相近,手术创伤小,损伤精索机会低,是一种更为合适的远端疝囊处置方法。
