Factors Affecting Recurrent Deep Vein Thrombosis after Pharmacomechanical Thrombolysis and Left Iliac Vein Stent Placement in Patients with Iliac Vein Compression Syndrome

PurposeThis study evaluated the factors affecting contralateral and ipsilateral recurrent deep vein thrombosis (DVT) after iliac vein stent placement in patients with iliac vein compression syndrome (IVCS).Materials and MethodsData from 130 patients (95 female patients) who underwent catheter-directed thrombolysis and stent placement for IVCS with left lower leg thrombosis at a single institution were retrospectively analyzed. Mean patient age was 69.0 ± 14.0 years old. Median follow-up was 14 months (range, 3–164 months). Anticoagulation therapy was prescribed for 6 months, followed by lifelong antiplatelet therapy. Multivariate logistic regression analysis was performed to evaluate the factors affecting the development of contralateral and ipsilateral recurrent DVT.ResultsSeven patients (5.4%) developed contralateral DVT (median, 26 months; range, 2–61 months), and 11 patients (8.5%) developed ipsilateral DVT (median, 1 month; range, 0–53 months). Stent location (odds ratio [OR], 11.564; 95% confidence interval [CI], 1.159–115.417) and in-stent thrombosis during follow-up (OR, 15.142; 95% CI, 1.406–163.119) were predictors of recurrent contralateral DVT. Thrombophilia (OR, 47.560; 95% CI, 2.369–954.711), remaining inferior vena cava filter (OR, 30.552; 95% CI, 3.495–267.122), and in-stent thrombosis during follow-up (OR, 82.057; 95% CI, 2.915–2309.848) were predictors of ipsilateral DVT.ConclusionsContralateral DVT occurs late and is associated with extension of the iliac vein stent to the inferior vena cava and in-stent thrombosis. Ipsilateral DVT occurs relatively early and is associated with thrombophilia, remaining inferior vena cava filter, and in-stent thrombosis.     

丽水市十三项呼吸道病原体感染情况及特点分析北大核心CSCD

目的了解丽水市呼吸道病原体感染情况及流行病学特征,为呼吸道传染病诊疗与防控提供科学依据。方法回顾性分析2020年3月至2021年12月丽水市人民医院收治的4035例呼吸道感染患者13项呼吸道病原体PCR毛细电泳核酸检测结果,并分析病原体感染分布特征。结果呼吸道病原体感染患者阳性检出率为32.24%(1301/4035),检出率前5位分别是HRV(16.60%)、HRSV(7.09%)、HPIV(2.87%)、HMPV(2.21%)、HADV(1.96%)。混合感染阳性占比为7.61%(99/1301),Boca病毒(76.0%)与Ch(46.15%)易与其它病原体形成混合感染。不同性别呼吸道病原体感染率差异无统计学意义(P>0.05)。虽然不同季节呼吸道病原体整体感染率差异无统计学意义(P>0.05),但HRV好发于春秋两季,而HPIV在春秋两季感染率较低,春季HRSV感染率较低,HADV在夏秋两季感染率较低,HMPV在冬季较为流行。未成年人呼吸道病原体感染率较高,HRSV、HRV、HPIV、HADV和Boca主要发生于未成年人组,InfB和HMPV在未成年和青年人群感染率都较高。结论未成年人群是呼吸道病原体易感人群,应加强未成年人呼吸道传染病防控。     

十二指肠镜治疗胆总管结石35例临床分析

目的探讨经十二指肠镜治疗胆总管结石的临床效果和价值。方法经十二指肠镜治疗胆总管结石共35例,其中行EST及取石术32例,行EPBD及取石术3例。EST胆总管取石时根据结石大小决定切开大小,不宜EST或结石较小者可选择EPBD后取石。结果35例均成功取出胆总管结石,取得较好的疗效。EST术中局部渗血4例,当时予电凝或喷洒止血药物即迅速止血,术后急性胰腺炎1例,经适当处理后1周痊愈,EPBD及取石术后未发现明显并发症。结论十二指肠镜治疗胆总管结石是一种微创、安全、有效的治疗方法。     

腹腔镜下胆总管探查术22例临床分析

目的探讨腹腔镜下胆总管探查术的方法及避免副损伤的措施.方法应用Olympus腹腔镜及操作器械一套.全麻下进行,体位及穿刺点均与腔镜胆囊切除相同.穿刺证实胆总管后,对胆总管直径＞1.5 cm者用针式电钩直接切开;胆总管直径＜1.2 cm者用剪刀切开,纵行切开1.0～1.5 cm,直视下用常规器械或胆管镜网篮取石,胆总管Ⅰ期缝合.结果本组22例中,21例成功,1例由于胆囊三角区粘连紧密,镜下缝合胆总管困难中转开腹手术.结论腹腔镜下胆囊切除,胆总管探查与传统开腹手术比较具有微创特点,胆总管Ⅰ期缝合更体现微创外科的优势.     

Neuropeptide levels in the basal ganglia of aged common marmosets following prolonged treatment with MPTP

Summary Aged common marmosets were treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP; 0.5–2.0 mg/kg/week i.p.) for 16 or 24 weeks, observed for a total of 30 weeks and then killed for measurement of biochemical pramaters in basal ganglia. The MPTP treatment induced a marked depletion in dopamine, 3,4-dihydroxyphenylacetic acid and homovanillic acid levels in the caudate nucleus and putamen. In contrast, the concentrations of five neuropeptides: [Met⁵]-enkephalin, [Leu⁵]-enkephalin, cholecystokinin, substance P and neurotensin as measured by a combined HPLC/RIA method, remained unaltered in all basal ganglia regions examined. Enkephalin precursor levels, as reflected by cryptic [Met⁵]-enkephalin content, were increased in the putamen, but not in the caudate nucleus, as a consequence of MPTP administration. Cryptic [Leu⁵]-enkephalin content remained unchanged in the striatum of MPTP treated marmosets. Overall, these results suggest an increase in striatal [Met⁵]-enkephalin release following chronic MPTP treatment of aged marmosets. However, the chronic treatment of aged marmosets with MPTP does not reproduce the neuropeptide alterations characteristic of Parkinson's disease.     

The case for laparoscopic common bile duct exploration

The modern surgeon's approach to choledocholithiasis depends his or her view of cholangiography. During the early 1990 there was a swing away from cholangiography, which had previously been common practice. This was because of perceptions of difficulty with the technique, the time it took, and perhaps an implied increase in costs because of the time factor. There was no evidence on which to base this decision. This led to a marked upswing in the use of endoscopic retrograde cholangiopancreatography (ERCP). There were a large number of ERCPs with normal results performed prior to laparoscopic cholecystectomy. This paper states the case for intraoperative cholangiography and common bile duct clearance at the time of cholecystectomy. It is hoped that this technique will be adopted so patients can undergo a single procedure to remove their gallstones and common bile duct stones if they exist and to decrease the incidence of normal preoperative ERCPs and the need for a second procedure postoperatively to clear stones if they are found.     

Thrombotic occlusion of the common carotid artery (CCA) in acute ischemic stroke treated with intravenous tissue plasminogen activator (TPA)

Although common carotid artery (CCA) occlusions are rare, acute clinical presentations vary from mild to devastating strokes primarily due to tandem occlusions in the intracranial arteries. Three patients with acute CCA occlusions were treated with systemic tissue plasminogen activator (TPA). Blood pressures were kept at the upper limits allowed with TPA therapy with fluid balance and the 'head-down' position. Recanalization occurred in intracranial vessels only. Marked early neurological improvement occurred in two of three patients. CCA occlusions should not be considered contra-indication to systemic thrombolysis.
