Influence of earthquakes on the occurrence of aortic aneurysm ruptures.

BACKGROUND: Catastrophic events have been correlated to increased incidence of cardio-vascular events, but no correlation between RAA and seismic activities have ever been investigated. METHODS: Hospital admissions related to RAA between January 2014 and December 2016 were retrospectively assessed in nine vascular centers of central Italy and correlated with date-matched seismic events. Correlation between RAA presentation and seismic event was first evaluated by Linear Regression analysis. Incidence of RAA events, mortality rate, and type of intervention were analyzed during seismic days (SD) and compared to outcomes during non-seismic days (nSD). RESULTS: A total of 376 patients were admitted with a diagnosis of RAA, and a total of 783 seismic events were reviewed. Twenty patients died before intervention (untreated). Open surgery was performed in 72.8%, endovascular treatment in 27.2%. General mortality at 30 days was 26.6% (30.5% for open surgery; 21.6% for endovascular treatment; P=0.24). Linear regression analysis between RAA and seismic periods revealed a significant correlation (slope=0.11±0.04, equation: y = 0.1143 x + 3.034, P=0.02). Incidence of RAA was 0.34 event per day during the entire period, 0.32 during nSD and 0.44 during SD (P=0.006). During seismic days, patients with RAA were older (80.5 years during SD vs. 77 years during nSD, P=0.12), were in poorer general condition at admission and remained untreated more frequently (8% SD vs. 4.7% nSD, P=0.3), and had a higher mortality rate at 30 days (46.2% SD vs. 27.2% nSD, P=0.012). CONCLUSIONS: During seismic days, the incidence of RAA is higher in comparison to non-seismic days. Patients with rupture during seismic days have a higher risk of death.

Thirty-day results from prospective multi-specialty evaluation of carotid artery stenting using the CGuard MicroNet-covered Embolic Prevention System in real-world multicentre clinical practice: the IRON-Guard study.

AIMS: The aim of the present study was to evaluate periprocedural and 30-day outcomes in a prospective series of patients treated with the CGuard Embolic Prevention System (EPS). METHODS AND RESULTS: From April 2015 to June 2016, a physician-initiated prospective multicentre study was performed in 200 consecutive patients admitted for protected carotid artery stenting (CAS) and treated using the CGuard EPS in twelve vascular centres. Outcome measures were: technical success, periprocedural (0-24 hours) and post-procedural (24 hours-30 days) major and minor strokes, death, acute myocardial infarction (AMI), transient ischaemic attack (TIA), and external carotid occlusion. In three centres, consecutive diffusion-weighted magnetic resonance cerebral imaging (DW-MRI) was performed ≤72 hours prior to and within 72 hours after the intervention. A distal embolic protection device was employed in 182 patients (91%). Technical success was 100%. No death, AMI or major stroke occurred periprocedurally. There were two TIAs and five periprocedural minor strokes (2.5%), including one thrombosis solved by surgery. In the remaining patients (199/200; 99.5%) one-month follow-up duplex ultrasound revealed optimal technical results. Post-procedural clinical follow-up was uneventful. No external carotid artery occlusion occurred. New post-procedural DW-MRI lesions were detected in 12 patients out of 61 (19.6%), including bilateral in five (8.2%) and isolated ipsilateral in six (9.8%), whereas one patient (1.6%) had contralateral only lesions. CONCLUSIONS: Multicentre multi-specialty use of the CGuard EPS in routine clinical practice was associated with no major periprocedural neurologic complications and a total elimination of post-procedural neurologic complications by 30 days.

[Left paraduodenal hernia: a case report and review of the literature]. / Ernia paraduodenale sinistra: case report e review della letteratura.

Paraduodenal hernia is a rare internal congenital hernia due to an embryological abnormality. It is often associated with non-specific abdominal symptoms. In this report the authors describe the case of a woman who was referred to the emergency ward for intestinal obstruction. Preliminary examinations (x-ray and computed tomography scan) failed to yield a clear diagnosis. The patient underwent a surgical procedure and a left paraduodenal hernia was diagnosed. A sound knowledge of embryological anatomy is essential for safe, effective surgical treatment of such internal hernias. A review of the literature confirms that this congenital abnormality is rare and that its diagnosis is the most difficult step in its therapeutic management.
