Screening for Peripheral Vascular Stiffness in Lipedema Patients by Automatic Electrocardiogram-Based Oscillometric Detection.

Body mass index (BMI) is seen as a predictor of cardiovascular disease (CVD) in lipedema patients. A valid predictor of CVD is increased aortic stiffness (IAS), and previous research described IAS in lipedema. However, it is not known if this applies to all patients. In this cross-sectional single-center cohort study, peripheral pulse wave velocity (PWV) as a non-invasive indicator of aortic stiffness was measured in 41 patients with lipedema, irrespective of stage and without pre-existing cardiovascular conditions or a history of smoking and a maximum body mass index (BMI) of 35 kg/m2. Automatically electrocardiogram-triggered oscillometric sensor technology by the Gesenius-Keller method was used. Regardless of the stage of lipedema disease, there was no significant difference in PWV compared to published standard values adjusted to age and blood pressure. BMI alone is not a predictor of cardiovascular risk in lipedema patients. Measuring other anthropometric factors, such as the waist-hip ratio or waist-height ratio, should be included, and the existing cardiovascular risk factors, comorbidities, and adipose tissue distribution for accurate risk stratification should be taken into account. Automated sensor technology recording the PWV represents a valid and reliable method for health monitoring and early detection of cardiovascular risks.

Management of the left subclavian artery during TEVAR - complications and mid-term follow-up.

BACKGROUND: Numerous conditions that affect the boundary between the aortic arch and descending aorta are treated with thoracic endovascular aortic repair (TEVAR). In 40 % of cases, coverage of the left subclavian artery (LSA) cannot be prevented. Subsequently, neurological complications such as stroke or ischemia of the left upper extremity may develop. However, the actual risk of these complications is subject to considerable controversy. The optimal treatment approach, specifically the question whether primary revascularization of the LSA should be performed in all cases, is unclear. PATIENTS AND METHODS: The present retrospective study analyzed the short- and mid-term results of patients treated with TEVAR with complete coverage of the LSA. The postoperative protocol consisted of clinical and noninvasive examinations as well as morphological imaging. Survival, complication, and reintervention rates were recorded. RESULTS: A total of 40 patients, undergoing TEVAR with complete coverage of the LSA between January 2010 and December 2014 were analyzed retrospectively. The 30-day survival rate was 95 %, the survival one year after performed TEVAR was 67.5 %. The average follow-up was 1.5 years. After TEVAR procedure with complete coverage of the LSA, only one patient (2.5 %) developed critical ischemia of the left arm immediately after aortic stent implantation, requiring revascularization by transposition of the LSA. Anterior spinal artery syndrome occurred in another patient (2.5 %) immediately following TEVAR. During follow-up examinations, all patients showed a compensated arterial arm status. None of the patients developed new neurological deficits during the follow-up period. CONCLUSIONS: The study shows that performing TEVAR without primary revascularization of the LSA was justifiable in our cohort. An important risk factor of developing cerebral ischemia seems to be insufficient collateralization through the circle of Willis.
