The aim of this study was to develop a short questionnaire measuring health-related quality of life (HRQoL) in chronic wounds. Three validated instruments assessing HRQoL in chronic wounds-the Freiburg Life Quality Assessment for wounds, the Cardiff Wound Impact Schedule, and the Würzburg Wound Score-were completed by 154 German leg ulcer patients in a longitudinal study. For implementation in the new, shorter questionnaire Wound-QoL, all of those 92 items that covered the core content of the three questionnaires and showed good psychometric properties were selected.

Managing graft infections is a challenge in vascular surgery. The incidence of vascular graft infections varies between 2% and 6%. The number of patients treated by means of implantation of artificial prostheses is constantly growing.

There are a lot of options, and the vascular therapist should be able to provide multiple alternatives. In this article we give on overview over the actual therapeutic options and present the data of a retrospective analysis of bypass occlusions.

Acute aortic syndromes (AAS) are life-threatening vascular conditions of the thoracic aorta presenting with acute pain as the leading symptom in most cases. The incidence is approximately 3-5/100,000 in western countries with increase during the past decades. Clinical suspicion for AAS requires immediate confirmation with advanced imaging modalities.

Endovascular treatment for initial damage control in arterial transection has evolved as a promising technique to improve outcome, but technical success can be limited in cases of complete transection as the lesion cannot be passed by a guidewire. This report describes an endovascular approach using a through-and-through brachial-femoral wire to control complete traumatic transection of the proximal axillary artery in a hemodynamically unstable patient.

We report the case of a 52-year-old HIV-positive patient who presented with a symptomatic, rapidly growing suprarenal abdominal aortic aneurysm. He had been diagnosed and treated for disseminated MAC infection 3 years earlier.

Technique: The "Knickerbocker technique" involves relining the true lumen in the descending aorta with an oversized thoracic tubular endograft, followed by controlled rupture of the dissection membrane using a large compliant balloon within the graft's midsection. This maneuver, which allows expansion of the stent-graft's midsection into the false lumen, was developed in order to occlude the large false lumen distally and thus prevent continued false lumen perfusion through distal abdominal entry tears.
Background: In the Gutenberg Health Study, a random sample of the population was scanned with vascular ultrasound for early atherosclerosis. A continuous classical risk marker model (waist circumference, HbA1c, LDL/HDL ratio, pack years and pulse pressure) was compared to a model of modern biomarkers (C-reactive protein, troponin I, N-terminal pro B-type natriuretic peptide, copeptin, mid-regional pro-adrenomedullin, and asymmetric dimethylarginine) with regard to the ability of ruling out abnormal intima-media thickness (IMT), respectively, carotid plaques.
Methods: Data of the first consecutive 5,000 participants (aged 35-74 years; 2,540 men, 2,460 women) were analyzed.
Carotid artery stenosis is a marker for generalized atherosclerosis with high cerebrovascular and cardiovascular morbidity and mortality rates. There is an estimated increase in prevalence of moderate stenosis for older age and male sex. Asymptomatic carotid artery stenosis is a risk factor for perioperative neurological events during general surgery.

She was treated successfully by plugging and coiling of the subclavian aneurysm and its side branches after combined cervical debranching using standard carotid-axillary bypass and Gore Hybrid Vascular Graft for vertebral revascularization. Follow-up control (4 weeks) documented patent debranching, and only minimal residual flow in the subclavian aneurysm.

Technique: The "candy-plug" technique is demonstrated in a 58-year-old multimorbid man with a history of complicated acute type B aortic dissection and a 9-cm chronic thoracic false lumen aneurysm. The patient underwent a staged repair with a cervical debranching procedure as a first step and a thoracic endovascular aortic repair from the innominate artery to the celiac artery as a second step.
Background: Endovascular treatment (ER) of renal artery aneurysms (RAA) has been widely used recently due to its assumed lower morbidity and mortality compared with open surgery (OS). The purpose of this study was to investigate the outcomes of OS and ER, and compare long-term renal function.
Study Design: Data from 2000 to 2012 were retrospectively collected to identify patients who were treated for RAA in a single institution.
Purpose: To report the use of antegrade in situ fenestration as a bailout technique to rescue a renal artery after inadvertent coverage during endovascular aneurysm repair (EVAR).
Technique: The technique is demonstrated in a patient with a 6-cm infrarenal abdominal aortic aneurysm (AAA) and a short, angulated proximal neck. A type I endoleak persisted on completion angiography after implantation of a bifurcated Zenith stent-graft despite dilation with a compliant balloon.
The treatment of abdominal aortic aneurysms (AAA) has changed significantly since the introduction of endovascular aortic repair (EVAR). In terms of perioperative morbidity and mortality, randomized multicenter trials revealed results in favour of EVAR compared to open reconstruction. However, EVAR is associated with possible late complications caused by endoleaks, stent migration, kinking and/or overstenting of side branches, making life-long follow-up necessary.

Methods: Six domestic pigs were operated with retrograde delivery of a single side branch arch endograft and antegrade introduction of a mating stent-graft using transseptal access (n=3) and transapical access (n=3). Technical feasibility, operating time, radiation parameters, and hemodynamic changes were studied.

Aim: The aim of this paper was to present a mathematical model to calculate the required main aortic graft-diameter for parallel chimney-grafts. Methods: Geometric approximation model, developed to allow for a standardized calculation of the main aortic graft-diameter determined by the aortic diameter and the diameter of the chimney-graft. Results: We propose a mathematical formula using circular segments of the aorta and the chimney-graft and provide a table with recommended main aortic graft-diameters for single chimney-grafts of 6 and 8 mm.

Unlabelled: Dabigatran, an oral, reversible direct factor IIa inhibitor, is approved in Europe for stroke prevention in atrial fibrillation and for the prevention of venous thromboembolism after elective hip and knee replacement. In contrast to vitamin K antagonists, a routine coagulation monitoring during the treatment with dabigatran etexilate is not necessary. However, in specific clinical situations such as invasive emergency procedures or serious haemorrhage, the actual anticoagulant status of dabigatran may be of importance for the treating clinician and can be assessed by clotting tests (aPTT, TT, ECT).
