Long-term gender-specific survival and cancer incidence in patients with ruptured abdominal aortic aneurysm (rAAA) were investigated after endovascular (EVAR) and open repair (OAR). : Data from 2933 patients (EVAR n = 1187, OAR n = 1746) from a health insurance company in Germany (men n = 2391, women n = 542) were analyzed. All patients were cancer-free in their history.

Background: In Germany, there is no data available on the frequency of inpatient rehabilitation (IR) after elective endovascular (EVAR) and open (OAR) abdominal aortic aneurysm (AAA) repair.

Objective: To report for the first time on the outcome of patients 65 years and older and thus of retirement age with and without IR after AAA repair in a retrospective analysis of routine data from all eleven regional companies of the AOK health insurance fund (AOK-Gesundheit).

Methods: Anonymized data of 16,358 patients 65 years and older with intact abdominal aortic aneurysm treated with EVAR (n = 12,960) or OAR (n = 3,398) between 01/01/2010 and 12/31/2016 were analyzed.

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.

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.

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).

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.

Article Synopsis
  • The study looked at how male and female patients with abdominal aortic aneurysms (AAA) respond to treatment and found that women tend to have worse outcomes than men.
  • It analyzed data from thousands of patients to compare factors like aneurysm size and how they relate to the risk of dying after surgery.
  • The results showed that even though women had smaller aneurysms, they had higher death rates after 30 days of surgery compared to men.

Purpose: The influence of cancer development on long-term outcome after elective endovascular (EVAR) vs. open repair (OAR) of non-ruptured abdominal aortic aneurysms (AAA) was investigated.

Methods: Patient survival and cancer incidence were recorded for 18,802 patients registered with the AOK health insurance company in Germany who underwent EVAR (n = 14,218) and OAR (n = 4584) in the years 2010 to 2016 (men n = 16,086, women n = 2716).

Methods: Anonymised data of all patients with rAAA (n = 3,227) who were treated from 01/01/2010 to 12/31/2016 were analysed, using SPSS 27 (IBM Deutschland GmbH, Ehningen, Germany).

Results: 41.

The current study aimed to investigate whether the in vivo availability of central serotonin reuptake transporters (5-HTT) is associated with plasma levels of glycosylated hemoglobin (HbA1c) in non-diabetic humans with obesity. 5-HTT availability was measured by using positron emission tomography (PET) imaging with the 5-HTT selective radiotracer [C]DASB in 23 non-diabetic individuals with obesity and 14 healthy, non-obesity controls. Parametric images of binding potential BP were generated from the PET data and analyzed together with HbA1c levels by using volume of interest analysis for brain areas relevant to appetite control.

Background: The MTL30 (mortality, transfer, length of stay) was proposed as a surrogate parameter for evaluating the quality of large and potentially complication-prone visceral surgical interventions.

Objective: The aim of this study was to find out to what extent the MTL30 can be correlated with the results of the abdominal aortic aneurysm (AAA) registry of the German Institute for Vascular Health Research (DIGG) of the German Society for Vascular Surgery and Vascular Medicine (DGG) and with the case volume of the participating hospitals.

Material And Methods: Elective endovascular abdominal aortic aneurysm repair (EVAR) was performed in 14,282 patients and open repair (OAR) in 3923 patients.
