女性生育力评估

随着人口老龄化和生育力的下降,我国放开了三孩政策,对有生育要求的夫妇进行生育力评估显得非常必要。女性生育力与年龄关系密切,还依赖于卵巢、输卵管、子宫等生殖器官。本文就影响女性生育力的因素进行介绍。     

不同介入方案治疗急性下肢静脉血栓的临床效果与安全性比较

目的 探讨不同介入方案治疗急性下肢静脉血栓(DVT)的临床效果与安全性。方法 选取我院2015年1月～2019年12月介入科收治的急性DVT患者54例作为研究对象,按照治疗方式的不同分为研究组27例和对照组27例。研究组采用血管腔内综合治疗,对照组采用导管介导溶栓治疗,比较两组患者疗效评价、治疗前后膝上、下15 cm与患肢周径差、治疗前后皮肤肿胀张力、静脉通畅率、住院时间和并发症发生情况。结果 经治疗后研究组患者膝上、下15 cm与患肢周径差均短于对照组(P0.05);经治疗后研究组患者皮肤肿胀张力恢复程度显著优于对照组(P0.05);经治疗后研究组患者静脉通畅率显著高于对照组(P0.05);研究组治疗有效率显著高于对照组(P0.05);研究组患者住院时间明显少于对照组,且其并发症发生率显著低于对照组(P0.05)。结论 血管腔内综合介入治疗能够有效改善患者下肢症状,提高DVT恢复情况,降低并发症的发生,从而有效提高患者生活质量,为临床治疗DVT提供重要参考。

Comparative outcomes of vascular access in patients older than 70 years with end-stage renal disease

Objective

The advantage of arteriovenous fistulas (AVFs) in older patients requiring dialysis is controversial. We reviewed our vascular access experience in patients ≥70 years of age (older group) compared with younger patients.

IN.PACT AV Access Trial: Economic Evaluation of Drug-Coated Balloon Treatment for Dysfunctional Arteriovenous Fistulae Based on 12-Month Clinical Outcomes

PurposeTo study, from a U.S. payer’s perspective, the economic consequences of drug-coated balloon (DCB) versus standard percutaneous transluminal angioplasty (PTA) use for the treatment of stenotic lesions in dysfunctional hemodialysis arteriovenous fistulae.Materials and MethodsCost differences between DCBs and PTA at year 1 and beyond were calculated via 2 methods. The first approach used the mean absolute number of trial-observed access circuit reinterventions through 12 months (0.65 ± 1.05 vs 1.05 ± 1.18 events per patient for DCBs and PTA, respectively) and projected treatment outcomes to 3 years. The second approach was based on the trial-observed access circuit primary patency rates at 12 months (53.8% vs 32.4%) and calculated the cost difference on the basis of previously published Medicare cost for patients who maintained or did not maintain primary patency. Assumptions regarding DCB device prices were tested in sensitivity analyses, and the numbers needed to treat were calculated.ResultsUsing the absolute number of access circuit reinterventions approach, the DCB strategy resulted in an estimated per-patient savings of $1,632 at 1 year and $4,263 at 3 years before considering the DCB device cost. The access circuit primary patency approach was associated with a per-patient cost savings of $2,152 at 1 year and $3,894 at 2.5 years of follow-up. At the theoretical DCB device reimbursement of $1,800, savings were $1,680 and $2,049 at 2.5 and 3 years, respectively. The one-year NNT of DCB compared to PTA was 2.48.ConclusionsEndovascular therapy for arteriovenous access stenosis with the IN.PACT AV DCB can be expected to be cost-saving if longer follow-up data confirm its clinical effectiveness.

三维超声自由解剖成像技术对早期宫角与间质部妊娠的诊断价值

【摘要】 目的 探讨三维经阴道超声自由解剖成像技术(3DTVUOT)对早期宫角妊娠(CP)与间质部妊娠(ITP)的定性诊断价值。 方法 回顾性分析35例CP和36例ITP患者的临床资料。均因临床疑诊早期CP或ITP被序贯予以二维经阴道超声(2DTVU)和3DTVUOT检查，对妊娠病灶与宫腔的相通情况、病灶周围肌层完整性和厚度情况等进行比较分析；以手术 病理结果作为诊断金标准，对两种检查方法应用于CP和ITP定性诊断中的敏感性、特异性及准确性进行比较。 结果 CP患者的妊娠病灶与宫腔相通率(9143％)高于ITP(833％),病灶周围包绕肌层的厚度(608±135） mm高于ITP (195±058）mm,完整性(100％)亦高于ITP的(7222％)，组间比较差异均有统计学意义（P＜005）。2DTVU定性诊断CP和ITP的敏感性(8611％)、特异性(7714％)及准确性(8168％)均明显低于3DTVUOT（分别9444％、8571％、9014％），组间差异具有统计学意义（P＜005）。 结论 3DTVUOT对CP和ITP的早期定性诊断，具有较高的可靠性，优于2DTVU，可在临床推广应用。     

Use of the Covera Stent Graft for the Treatment of Dysfunctional or Thrombosed Arteriovenous Grafts: A Retrospective Analysis of 64 Patients

PurposeTo retrospectively evaluate the safety and effectiveness of the Covera stent graft (SG) for the treatment of dysfunctional or thrombosed arteriovenous grafts (AVGs).Materials and MethodsWithin 29 months (February 2016–August 2018), 79 patients underwent Covera SG placement in the authors’ department for the treatment of dysfunctional AVGs. Data were available for 64 patients who underwent 64 procedures, using 64 devices. Minimum follow-up was 6 months, unless reintervention occurred. Mean follow-up was 277 days (6–923 days). Treatment characteristics were 51 cases with venous-graft anastomosis (VGA) stenosis (79.7%), 13 cases of puncture zone stenosis (20.3%), 14 cases of in SG stenosis (21.9%), 8 cases of pseudoaneurysm treatment (12.5%) (1 treatment area might have had more than 1 characteristic). Thirty-six patients presented with thrombosis (56.2%), and 31 of 64 case were de novo treatment areas (48.4%). Primary outcome measurements were technical success and post-intervention primary patency (PIPP) at 6 months, whereas secondary outcome measurements included factors influencing primary outcome.ResultsTechnical success was 100%. Median PIPP was 336 days, and 73.6% of treatment areas were patent at 6 months. There were no significant differences in terms of PIPP when de novo treatment areas were compared with restenotic areas (519 vs. 320 days, respectively; P = .1); patients who presented with versus those who presented without thrombosis (320 vs. 583 days, respectively; P = .07); puncture zone stenosis or elsewhere (329 vs. 686 days, respectively; P = .52); and VGA stenosis or elsewhere (336 vs. 335 days, respectively; P = .9).ConclusionsUse of the Covera SG for AVG treatment was safe and effective in every type of treatment area presented in this retrospective analysis.     

Paclitaxel drug-coated balloon angioplasty for the treatment of failing arteriovenous fistulas: a single-center experience

Abstract

Objectives: To report our experience of angioplasty with Lutonix (Bard Peripheral Vascular, Inc., Tempe, AZ) drug-coated balloon (DCB) for the treatment of failing arteriovenous fistulas (AVF).

Materials and methods: Retrospective, single-center analysis consisting of 14 patients treated with Lutonix paclitaxel DCBs in the period from July 2015 through April 2017. We analyzed technical success, clinical success, primary patency of the target lesion, primary patency of the dialysis circuit, and the rate of complications. Regular follow-up of AVF patency was realized by clinical examination and duplex ultrasonography. The Kaplan–Meier survival method was applied to determine the cumulative primary patency of the target lesion and the dialysis circuit.

Results: Technical success was 100% and clinical success 92.9%. There were no major or minor complications. Cumulative target lesion primary patency after DCB was 69.2% at 6 months and 31.6% at 12 months. Cumulative vascular circuit primary patency was 61.5% at 6 months and 31.6% at 12 months.

Conclusion: Compared to results reported in literature with plain old balloon angioplasty (POBA), Lutonix paclitaxel DCB angioplasty proved a short-term patency benefit in treatment of dialysis AVF stenosis.     

Ectopic pregnancy in the ampulla of the fallopian tube at 16 gestational weeks: lessons from a case report

BackgroundIt is uncommon to find ampullary tubal pregnancy in the second trimester.MethodsA 35-year-old G4P3 at 16 gestational weeks presented with a day history of sudden severe lower abdominal pain and no vaginal bleeding. The patient had a normal pulse of 82/minutes, haemoglobin concentration of 6.3 g/dl and ultrasonography showed an empty uterus with an alive fetus in the right adnexa. She was provisionally diagnosed to have an abdominal pregnancy.ResultsThe patient had an emergency laparotomy where 2.2 L of haemoperitoneum and a slow-leaking right ampullary tubal pregnancy were found. Right total salpingectomy was performed and she had an uncomplicated post-operative follow-up. Histology of the lesion confirmed tubal pregnancy.ConclusionThe growth of a pregnancy in the ampulla beyond the first trimester is possibly due to increased thickness and or distensibility of the fallopian tube. A tubal pregnancy may present with a normal pulse despite significant haemorrhage.
