Clinical profile and one-year outcomes of patients with mural infective endocarditis: – A tertiary care centre study based on data from a seven-year registry

BackgroundInfective endocarditis patients present very rarely with vegetations on the mural endocardium. Only very few studies are available comparing Mural infective endocarditis with commoner valvular or device related infective endocarditis.AimTo analyse the clinical features, microbiological profile and clinical course of mural endocarditis in comparison to valvular endocarditis.MethodsThis was a retrospective analysis of data from a registry of infective endocarditis. Patients enrolled between April 2012 and April 2019 were included. Patients who were reported to have vegetations on the mural endocardial surface were taken as a group and compared with rest of the patients. Clinical profile, laboratory parameters including culture and outcomes were compared between the two groups.ResultsOut of 278 patients in the study, 15 (5.38%) had vegetations on the mural endocardium. Of them, only 4 patients had structural heart diseases. All the patients with mural endocarditis were NYHA class II or below at presentation. Ventricles were the commonest sites of vegetations. Inflammatory markers like ESR and CRP were low in mural endocarditis compared to rest. Culture positivity was high in mural endocarditis and Staphylococcus Aureus was the commonest organism. Mural endocarditis patients had similar in hospital mortality to rest of the patients. Cardiac complications were not reported in mural endocarditis, but they had similar incidence of embolic complications including neurological events.ConclusionMural endocarditis is a rare clinical entity with similar morbidity and mortality to that of endocarditis with valvular vegetation.     

Intra-operative pulmonary embolism after intravesical instillation of formalin

Intra-operative pulmonary embolism is a rare and severe complication which is difficult to diagnose. A case is reported in which this condition occurred after intravesical instillation of formalin during radical cystectomy under general anaesthesia. Formalin may be related to formation of intravascular thrombi and result in pulmonary embolism.     

经支气管动脉灌注丹参联合动脉化学栓塞术治疗中晚期肺癌的疗效分析

目的：探讨经支气管动脉灌注丹参联合动脉化学栓塞术治疗中晚期肺癌的近期疗效。方法：对31例经病理学确诊的原发性中心型肺癌进行选择性支气管动脉造影，并将3F同轴微导管置于肿瘤的供血动脉内灌注复方丹参注射液16ml，随之在透视监视下注入适当剂量的碘化油一顺铂乳剂。结果：临床症状改善率为100％，且无严重并发症发生，1年生存率为90．32％(28／31)。结论：经支气管动脉灌注丹参联合化学栓塞术治疗中晚期肺癌具有较好的临床疗效。     

肺动脉栓塞32例的临床特征及诊断思路

目的　提高肺动脉栓塞的诊断意识和诊断技术。方法　回顾性分析 32例肺动脉栓塞患者的基础疾病、诱因、临床表现和辅助检查以及诊疗及预后情况。结果　 32例肺动脉栓塞中下肢深静脉血栓形成是主要病因 ,病死率 34 .4 % ;误诊率 75% ;误诊与肺动脉栓塞的临床表现特异性不高。结论　医生的诊断意识不强和诊断水平不高有关 ,提高对肺动脉栓塞的诊断意识和诊断水平是减少误诊的关键     

颅内后循环远端动脉瘤的介入治疗

目的回顾性分析20例以电熔断解脱弹簧圈栓塞的后循环远端动脉瘤的治疗结果,探讨颅内动脉后循环远端动脉瘤的介入治疗方法与安全性。方法20例患者(其中18例以自发性蛛网膜下腔出血起病,2例以头痛起病)经造影证实大脑后动脉、小脑上动脉、小脑前下动脉、小脑后下动脉之远端动脉瘤分别为2例、4例、4例、10例。其中小脑上动脉供血之动静脉畸形1例,伴有血流相关破裂动脉瘤。小脑后下动脉远端多发动脉瘤1例。所有动脉瘤均采用GDC、EDC或Matrix弹簧圈栓塞。其中单纯栓塞动脉瘤2例;栓塞动脉瘤同时栓塞载瘤动脉18例。结果所有病例栓塞操作均顺利完成,无手术相关的死亡,术后出现一过性功能障碍2例;载瘤动脉栓塞后多数可见侧支供血,未见叫显的小脑供血减少。结论后循环远端动脉瘤由于动脉瘤特性、载瘤动脉细小、动脉瘤与载瘤动脉比例等因素,多需要闭塞载瘤动脉。为避免可能造成的侧支血管的闭塞,建议用弹簧圈栓塞。     

三维数字减影血管造影在颅内动脉瘤诊疗中的应用价值

目的：探讨3D—DSA在颅内动脉瘤诊断和治疗中的应用价值。方法：对蛛网膜下腔出血患者常规行DSA检查，发现病变或可疑病变后行3D—DSA检查。结果：26例颅内动脉瘤中检出动脉瘤31枚，其中后交通9枚，C1段3枚，C2段5枚，C3段3枚，前交通6枚，大脑中3枚。椎动脉动2枚。3例2D—DSA未见病变3D—DSA确诊，5例因血管重叠3D—DSA排除了动脉瘤。6枚GDC栓塞，5枚手术夹闭，2枚颈内动脉可脱性球囊封阻术。结论：3D—DSA极大提高了脑血管造影检查的准确性和可靠性，为动脉瘤的介入治疗和手术夹闭提供了可靠保障，在临床诊疗中具有很高的应用价值。     

创伤性肾动静脉瘘的介入治疗

目的 评价用介入技术治疗创伤性肾动静脉瘘(RAVFs)的安全性和疗效。方法 对8例不适宜做外科治疗的RAVFs患者进行了介入治疗，其中外伤性损伤4例，医源性损伤4例。6例行经导管超选择性肾动脉内钢丝圈栓塞术，2例行被覆膜支架置入患侧肾动脉内封闭瘘口。结果 血管造影显示肾内型动静脉瘘4例，累及肾动脉段-亚段级分支；主干(肾外)型动静脉瘘4例。治疗均获成功，治疗结束时复查血管造影显示瘘口被封闭。轻微并发症1例。医源性RAVFs患者术后失血症状迅速改善，肉眼血尿消失；4例术前存在心脏负荷过度症状患者，闭塞动静脉瘘后症状迅速改善，血管杂音消失。术后肾功能测定均属正常范围，其中2例肾动脉被覆膜支架置入患者，同位素肾扫描显示患侧肾脏形态、功能正常。术后随访10～42个月，2例分别于术后10，18个月死于与RAVFs无关的疾病。6例仍然生存，一般情况良好，未再针对RAVFs进行外科或介入治疗。结论 介入技术，包括经导管超选择性肾动脉内栓塞术和被覆膜支架置入术，是治疗创伤性、复杂型RAVFs的安全、有效的方法。     

急性肠系膜上动脉栓塞的诊断与治疗

目的: 探讨急性肠系膜上动脉栓塞的诊断与治疗。方法:对近10年收治的急性肠系膜上动脉栓塞患者22例临床资料进行回顾分析。结果:术前确诊率为77.3%，2例非手术治疗者均死亡（病死率100.0%）。20例经手术治疗，其中5例行单纯坏死肠管切除，端端吻合术，3例死亡（病死率60.0%）；15例行肠系膜上动脉取栓加坏死肠管切除，5例死亡（病死率33.3%）。总病死率为45.5%。结论:对于有器质性心脏病的患者，突然出现腹部疼痛，应警惕肠系膜上动脉栓塞的可能。CTA是诊断急性肠系膜上动脉栓塞的有效手段。早诊断、早期行肠系膜上动脉取栓术是提高治愈率的关键。
