Exploring the Effects of Local Air Pollution on Popliteal Artery Aneurysms.

A growing body of evidence highlights the effects of air pollution on chronic and acute cardiovascular diseases, such as associations between PM and several cardiovascular events. However, evidence of the impact of fine air pollutants on the development and progression of peripheral arterial aneurysms is not available. Data were obtained from the multicenter PAA outcome registry POPART and the German Environment Agency.

Deciphering Popliteal Artery Aneurysm Patient Diversity: Insights From a Cluster Analysis of the POPART Registry.

Background: Popliteal artery aneurysms (PAAs) are the most common peripheral aneurysm. However, due to its rarity, the cumulative body of evidence regarding patient patterns, treatment strategies, and perioperative outcomes is limited. This analysis aims to investigate distinct phenotypical patient profiles and associated treatment and outcomes in patients with a PAA by performing an unsupervised clustering analysis of the POPART (Practice of Popliteal Artery Aneurysm Repair and Therapy) registry.

Allerdings fehlt bisher eine allgemein akzeptierte Legaldefinition von Fachkliniken.

Prospects of Endovenous Laser Ablation (EVLA) Standardization-Mid-Term Results of a Four-Zone Dosimetry Guiding Tool for 1940 nm Laser.

Background: Heterogeneity regarding dosimetry and reporting of endovenous laser ablation (EVLA) mandates the development of a standardized protocol. This study presents the mid-term results of EVLA with 1940 nm-laser and radial-fibre, supported by a four-zone dosimetry tool.

Materials And Methods: Four anatomical dosimetry zones for great saphenous veins (GSV) and two for small saphenous veins (SSV) were defined with set power levels.

The Treatment of Patients With an Unruptured Abdominal Aortic Aneurysm and a Concomitant Malignancy.

Background: Having cancer adversely effects the outcome of treatment for an unruptured abdominal aortic aneurysm (AAA).

Methods: A retrospective secondary analysis was performed on the basis of anonymized data from AOK, a German nationwide statutory healthinsurance carrier. Data were evaluated from all of the 20 683 patients who underwent either endovascular (EVAR, 15 792) or open surgical (OAR, 4891) treatment for an unruptured AAA in the years 2010-2016.

Long-Term Outcome of Intact Abdominal Aortic Aneurysm After Endovascular or Open Repair.

Objective: Endovascular aortic aneurysm repair (EVAR) has been established as a standard treatment option for intact abdominal aortic aneurysm (iAAA) and gained importance due to a lower perioperative mortality than open repair (OAR). However, whether this survival advantage can be maintained or if OAR is beneficial in terms of long-term complications and reinterventions remains questionable.

Design: In this retrospective cohort study data from patients undergoing elective EVAR or OAR for iAAAs in the years 2010-2016 was analyzed.

[Long-term Results after Endovascular and Open Repair of Ruptured Abdominal Aortic Aneurysm - a Propensity Score Matched Analysis].

Background: This retrospective propensity score matched study presents the perioperative mortality and long-term survival up to 9 years after endovascular (EVAR) and open (OAR) repair of patients with ruptured abdominal aortic aneurysm (rAAA) in Germany using health insurance data.

Materials And Methods: 2170 patients treated between January 1st, 2010 and December 31st, 2016, for rAAA within 24 hours of hospital admission and receiving blood transfusions were enrolled in the study and tracked until December 31st, 2018. For better comparability of EVAR and OAR, a 1:1 propensity score matching with 624 pairs according to patient age, sex and comorbidities was carried out using the R program (Foundation for Statistical Computing, Vienna, Austria).

Outcomes of endovascular repair of infrarenal penetrating aortic ulcers.

To report technical success as well as perioperative outcomes of patients who underwent endovascular aortic repair (EVAR) of penetrating abdominal aortic ulcers ≤35 mm in diameter (PAU). The abdominal aortic aneurysm (AAA) quality registry of the German institute for vascular research (DIGG) was used to identify patients with standard EVAR for infrarenal PAU ≤35 mm between 1/1/2019 and 12/31/2021. Infectious, traumatic, inflammatory PAUs, PAUs associated with connective tissue disease, PAUs following aortic dissection as well as true aneurysms were excluded.

Changes in Aortic Diameter and Wall Strain in Progressing Abdominal Aortic Aneurysms.

Objectives: The analysis of wall strain opens new perspectives in the prediction of abdominal aortic aneurysm (AAA) rupture. This study investigates the capability of four-dimensional ultrasound (4D US) to detect and characterize changes in wall strain in the same patients during follow-up observations.

Methods: Eighteen patients were examined by 64 4D US scans during a median follow-up period of 24.

Age and Oversizing Influence Iliac Dilatation after EVAR.

In the past two decades, endovascular aortic repair (EVAR) of abdominal aortic aneurysm (AAA) has become the first line treatment for infrarenal AAA repair in many countries. While short-term results are good, concerns have been raised about long-term durability. Changes in aortoiliac anatomy, especially at the landing zones, could play a role in EVAR failure over time.

Changes in miRNA expression in patients with peripheral arterial vascular disease during moderate- and vigorous-intensity physical activity.

Background: Walking is the preferred therapy for peripheral arterial disease in early stage. An effect of walking exercise is the increase of blood flow and fluid shear stress, leading, triggered by arteriogenesis, to the formation of collateral blood vessels. Circulating micro-RNA may act as an important information transmitter in this process.
