The Influence of the Socioeconomic Status and the Density of the Population on the Outcome After Peripheral Artery Disease.

BACKGROUND: Low socioeconomic status (SES) and living in a rural environment are associated with poorer health and a higher number of amputations among the population at large. The purpose of this study is to determine the influence of low SES and of the degree of urbanization on the short-term and long-term results of patients after revascularization for peripheral artery disease. METHODS: An observational retrospective follow-up study of 770 patients operated on for peripheral artery disease at three university centers in north-western Spain from January 2015 to December 2016. The events studied were Rutherford classification of severity upon admission, direct amputation, amputations in the follow-up period, new revascularization procedures, major adverse cardiovascular events (MACE), and overall mortality. Mean personal income and income of the household associated with the street in which each patient lived and the degree of urbanization in three areas as per Eurostat criteria: densely populated areas, intermediate density areas, and thinly populated areas. Comorbidity, surgical, and follow-up variables were also collected. Descriptive analysis and Cox regression were used. Approval was obtained from the regional ethics committee. RESULTS: Median follow-up was 47.5 months. MACE occurred in 21.5% of the series and overall mortality was 47.0%. Living in a thinly populated area is associated with a lower risk of MACE (adjusted subhazard ratio = 0.60; 95% confidence interval [CI]: 0.39-0.91). Overall survival is lower in intermediate density area patients (adjusted Hazard Ratio = 1.46; 95% CI: 1.07-2.00). The third quartile of mean personal and household income is associated with a higher risk of major amputation at follow-up (adjusted Odds Ratio 1.92, 95% CI: 1.05-3.52 and adjusted Odds Ratio 1.93, 95% CI: 1.0.3-3.61, respectively). CONCLUSIONS: Patients who live in a densely populated area run a higher risk of MACE. SES is neither associated with worse outcomes after surgery nor with MACE in long-term follow-up.

Results of the Galician registry in the treatment of complex aortoiliac aneurysms with GORE® EXCLUDER® Iliac Branch Endoprosthesis (GALIBER).

OBJECTIVE: The objective of this study is to report the medium-term results of GORE® EXCLUDER® Iliac Branch Endoprosthesis (IBE, W. L. Gore & Associates, Flagstaff, Ariz) for the treatment of aortoiliac aneurysms by using the GALIBER registry. METHODS: Patients with aortoiliac or isolated common iliac/hypogastric aneurysms treated with Iliac Branch Endoprosthesis device between January 2014 and May 2019 were prospectively collected from 5 centers. Demographic, clinical, and radiologic data were extracted from electronic databases. Technical success was defined as successful implantation of the Iliac Branch Endoprosthesis device with exclusion of aortoiliac aneurysm, as well as patency of Iliac Branch Endoprosthesis in the follow-up. Iliac Branch Endoprosthesis patency was evaluated by Doppler ultrasound and/or computed tomography based on the protocol of each participant center. Follow-up was 731 days +/- 499. RESULTS: Between January 2014 and May 2019, 105 iliac arteries were treated with GORE® IBE device, in 81 patients (79 men, two women; mean age 71, range 52-91). Only seven patients (8.6%) were symptomatic. 60 patients (74%) had aortic and iliac enlargement. Thirty-three patients presented bilateral iliac aneurysms (40.7%): In twenty-four (29.6%) patients, an Iliac Branch Endoprosthesis device was implanted in both sides, and in nine patients (11.1%), one Iliac Branch Endoprosthesis was used with the embolization of the contralateral hypogastric artery. Technical success was achieved in the 99% (104/105 iliac branch device implanted). There were no procedural deaths or type I or III intraoperative endoleaks observed. During the follow-up (range 55-1789 days), 28 (34.5%) type II endoleaks were observed and one (1.2%) type Ia was observed. The patency of the hypogastric arteries treated with the iliac branch device was 98.1% during the follow-up (range 55-1789 days). In 30% of the patients with contralateral hypogastric embolization, some kind of complications was observed in the embolizated side: one developed ischemic colitis and two buttock claudication. CONCLUSIONS: Preservation of internal iliac artery with the Iliac Branch Endoprosthesis device can be performed safely with excellent technical success and good medium-term patency rates. These results support hypogastric preservation whenever possible to prevent ischemic complications.

Unusual Case of Superior Vena Cava Syndrome Caused by Intravascular Thyroid Metastasis.

Superior cava venous obstruction use to show a typical clinical presentation and a CT scan or even an ultrasonography can be sufficient to achieve an accurate diagnosis, but in this case, to obtain the final diagnosis, a multimodal assessment is needed. This case report shows a multidisciplinary approach which helped diagnose a complicated case, where conventional diagnostic methods were not enough.
