Z形皮瓣及推进皮瓣修复眼睑缺损的作用探讨

目的探讨眼睑恶性肿瘤切除术中应用Z形皮瓣及推进皮瓣I期修复眼睑缺损的临床效果。方法将50例眼睑恶性肿瘤切除术患者按不同缝合方法分为两组,即对照组25例,术中直接缝合;观察组25例,术中行Z形皮瓣及推进皮瓣I期修复;比较两组眼睑修复效果。结果观察组术后皮瓣成活率96.0%、切口Ⅰ期愈合率100%、修复满意率92.0%,均高于对照组的72.0%、68.0%、56.0%,差异有统计学意义(P<0.05)。观察组术后并发症发生率低于对照组,但差异无统计学意义(P>0.05)。结论眼睑恶性肿瘤切除术中眼睑缺损修复时,采用Z形皮瓣及推进皮瓣,眼睑修复良好,患者修复满意率高,值得推广应用。     

不同修复方法修复口腔颌面部肿瘤术后缺损的效果比较

目的探讨不同修复方法修复口腔颌面部肿瘤术后缺损的效果。方法选取口腔颌面部肿瘤根治术后缺损患者89例,根据最终选取的修复方案分为A组(n=49)和B组(n=40),A组给予股前外侧嵌合皮瓣修复,B组给予串联皮瓣修复。观察2组手术情况,采用华盛顿大学头颈肿瘤生活质量量表(UW-QOL)对患者术后生活质量进行评价,检测唾液中唾液酸(SA)及癌胚抗原(CEA)水平。结果A组手术时间、胃管拔除时间和经口进食时间分别为(6.30±1.19)h、(19.77±2.81)d和(20.32±2.19)d,明显少于B组(P<0.05);但A组皮瓣制作时间为(1.20±0.28)h,明显多于B组(P<0.05)。A组术后6个月UW-QOL量表中外观、吞咽、咀嚼、言语、肩功能、情绪评分分别为(63.29±4.54)分、(54.93±5.03)分、(47.12±6.02)分、(64.49±4.33)分、(82.20±5.43)分和(75.50±7.20)分,明显高于B组(P<0.05)。A组和B组术后6个月UW-QOL量表中疼痛、活动、娱乐、味觉、唾液及焦虑评分比较差异无统计学意义(P>0.05)。A组修复后1个月唾液中SA和CEA分别为(7.29±1.33)ng/dl和(50.04±16.62)ng/ml,明显低于B组(P<0.05)。A组血管危险发生率为2.04%,明显低于B组(P<0.05)。A组和B组感染、皮瓣坏死发生率差异比较无统计学意义(P>0.05)。结论相比较串联皮瓣修复,股前外侧嵌合皮瓣修复口腔颌面部肿瘤根治术后缺损有较好的效果,可以改善患者生活质量。     

Cardiac-type total anomalous pulmonary venous return is not benign

ObjectiveThe objective of this study was to investigate the association between morphological variation and postsurgical pulmonary vein (PV) stenosis (PPVS) in patients with cardiac total anomalous pulmonary venous connection (TAPVC).MethodsThis single-center, retrospective study included 168 pediatric patients who underwent surgical repair of cardiac TAPVC from 2013 to 2019 (connection to the coronary sinus [CS], n = 136; connection directly to the right atrium [RA], n = 32). Three-dimensional computed tomography modeling and geometric analysis were performed to investigate the morphological features; their relevance to the PPVS was examined.ResultsThe connection type had no association with PPVS (CS type: 18% vs right atrial type: 19%; P = .89) but there was a higher incidence of PPVS in patients with a single PV orifice than > 1 orifice (P < .001). Confluence-to-total PV area ratio (hazard ratio, 4.78, 95% CI, 1.86-12.32; P = .001) and length of drainage route (hazard ratio, 1.22; 95% CI, 1.14-1.31; P < .001) had a 4- and 1-fold increase in the risk for PPVS in the CS type after adjustment for age and preoperative pulmonary venous obstruction. In the right atrial type, those with anomalous PV return to the RA roof were more likely to develop PPVS than to the posterior wall of the RA (P < .001).ConclusionsThe number of inter-junction PV orifice correlated with PPVS development in cardiac TAPVC. The confluence-to-total PV ratio, length of drainage route, and anomalous PV return to the RA roof are important predictors for PPVS. Morphological subcategorization in this clinical setting can potentially assist in surgical decision-making.     

Ostium primum atrial septal defect with persistent left superior vena cava opening into unroofed coronary sinus—A rare entity

Raghib syndrome is a rare developmental complex consisting of termination of the left superior vena cava in the left atrium, absence of the coronary sinus, and an atrial septal defect commonly located at the posterior‐inferior angle of the atrial septum. This complex was considered unique to Raghib syndrome; however, cases with a normal atrial septum have been reported where the orifice of the unroofed coronary sinus functions as the inter‐atrial communication. Our patient demonstrated an isolated persistent left superior vena cava draining into the left atrium through unroofed coronary sinus and presence of ostium primum atrial septal defect.     

Electro‐vectorcardiographic demonstration of bifascicular block associated with ventricular preexcitation

Down syndrome occurs more frequently in the offsprings of older pregnant women and may be associated with atrioventricular septal defect. This refers to a broad spectrum of malformations characterized by a deficiency of the atrioventricular septum and abnormalities of the atrioventricular valves caused by an abnormal fusion of the superior and inferior endocardial cushions with the midportion of the atrial septum and the muscular portion of the ventricular septum.
