Ultrasound evaluation of the uterus in the uncomplicated postpartum period: a systematic review

The aim of this systematic review and meta-analysis was to define the means and the upper limits of normal for endometrial thickness and uterine measurements in uncomplicated pregnancies at different postpartum periods

Significance and Risk Factors for Intraprosthetic Mural Thrombus in Abdominal Aortic Endografts: a Systematic Review and Meta-Analysis

The detection of intraprosthetic thrombus (IPT) deposits is a common finding during follow-up for endovascular abdominal aneurysm repair (EVAR); however, its clinical significance is still debated. The aim of this study was to determine if IPT represents a risk factor for thromboembolic events (TE; endograft or limb thrombosis, or distal embolization) after EVAR

Title: Systematic Review and Meta-Analysis of the Outcome of Different Treatments for Type 1a Endoleak Following EVAR

and key words BACKGROUND: Insufficient evidence is available to recommend a particular strategy for the treatment of type 1a endoleaks (T1aEL) following endovascular abdominal aneurysm repair (EVAR). The aim of this study was to report outcomes of the different treatment modalities proposed for persistent and late-occurring T1aEL after EVAR

The Utility of Intraoperative Contrast-enhanced Ultrasound for Immediate Treatment of Type Ia Endoleak during EVAR: Initial Experience

Objectives Type Ia endoleak (EL) after endovascular abdominal aortic repair (EVAR) may be misdiagnosed at completion angiography. Intraoperative contrast-enhanced ultrasound (CEUS) may play a role in early detection and immediate treatment of type Ia EL. Methods From January 2017 to April 2018, patients treated with EVAR underwent intraoperative CEUS. After endograft deployment and ballooning, digital subtraction angiography (DSA) and intraoperative CEUS were performed in a blinded fashion. All cases of type Ia EL at DSA or CEUS were considered. Results Type Ia EL detected at intraoperative CEUS and undetected at DSA was defined in 2 patients. The former was solved with intraoperative re-ballooning; in the latter case, a Palmaz stent deployment was required. The resolution of type Ia EL was detected at intraoperative CEUS control and post-operative computed tomography angiography (CTA). In another patient, the DSA detected a type Ia EL, but intraoperative CEUS reveal a type II EL from lumbar arteries. Post-operative CTA confirm the type II EL. Conclusions The reported cases prove the clinical utility of the intraoperative CEUS, permitting the early identification of 2 type Ia EL. In addition, the intraoperative CEUS is useful in case of dubious type Ia EL at DSA, avoiding unnecessary intraoperative adjunctive procedure or post-operative CTA

Prevalence, risk factors and clinical impact of intraprosthetic thrombus deposits after EVAR

The aim is to define the prevalence, the evolution and the clinical relevance of the intraprosthetic thrombus deposit (IPT) after endovascular abdominal aortic repair (EVAR)

Early and mid-term results in the endovascular treatment of popliteal aneurysms with the multilayer flow modulator

Background The endovascular approach became an alternative to open surgical treatment of popliteal artery aneurysm over the last few years. Heparin-bonded stent-grafts have been employed for endovascular popliteal artery aneurysm repair, showing good and stable results. Only few reports about the use of multilayer flow modulator are available in literature, providing small patient series and short follow-up. The aim of this study is to report the outcomes of patients with popliteal artery aneurysm treated with the multilayer flow modulator in three Italian centres. Methods We retrospectively analysed a series of both symptomatic and asymptomatic patients with popliteal artery aneurysm treated with the multilayer flow modulator from 2009 to 2015. Follow-up was undertaken with clinical and contrast-enhanced ultrasound examinations at 1, 6 and 12 months, and yearly thereafter. Computed tomography angiography was performed in selected cases. Primary endpoints were aneurysm sac thrombosis; freedom from sac enlargement and primary, primary-assisted and secondary patency during follow-up. Secondary endpoints were technical success, collateral vessels patency, limb salvage and aneurysm-related complications. Results Twenty-three consecutive patients (19 males, age 72 ± 11) with 25 popliteal artery aneurysms (mean diameter 23 mm ± 1, 3 symptomatic patients) were treated with 40 multilayer flow modulators during the period of the study. Median follow-up was 22.6 ± 16.7 months. Complete aneurysm thrombosis occurred in 92.9% of cases (23/25 cases) at 18 months. Freedom from sac enlargement was 100% (25/25 cases) with 17 cases of aneurysm sac shrinkage (68%). At 1, 6, 12 and 24 months, estimated primary patency was 95.7%, 87.3%, 77% and 70.1%, respectively. At the same intervals, primary-assisted patency was 95.7%, 91.3%, 86% and 86%, respectively, and secondary patency was 100%, 95.7%, 90.3% and 90.3%, respectively. Technical success was 100%. The collateral vessels patency was 72.4%. Limb salvage was 91.4% at 24-month follow-up. One multilayer flow modulator fracture was reported in an asymptomatic patient. Conclusions Multilayer flow modulator seems a feasible and safe solution for endovascular treatment of popliteal artery aneurysms in selected patients
