Background: Diabetic foot ulcers are chronic, difficult to heal, and potentially life-threatening. Few medical devices have been studied in diabetic ulcers penetrating to bone or tendon.
Methods: We conducted an international, open-label randomized controlled trial, randomly assigning patients with diabetic ulcers penetrating to bone, joint, or tendon 1:1 to intact fish skin graft or standard wound care, with assigned treatment applied through 14 weeks.
Background: Due to new legal requirements, a patient-relevant benefit for other wound treatment products (sPW) must be demonstrated through clinical studies if reimbursement at the expense of the statutory health insurance is sought in the non-inpatient sector.
Method: An interdisciplinary group with expertise in clinical wound care has developed general recommendations for the design of suitable studies. In addition to regulatory documents, previous studies that have already been recognized as proof of benefit in other areas served as a basis.
Background: The questionnaire for the quality of life with chronic wounds (Wound-QoL) is a valid and reliable instrument to determine the disease-specific health-related QoL of patients with chronic wounds. For the interpretation of HRQoL scores, it is additionally important to know which differences in scores are considered meaningful. The minimal important difference (MID) is defined as a change in HRQoL that a patient would consider meaningful, such that the patient would judge a treatment to be beneficial and worthy of repeating.

Methods: Endografts were flushed with 50 mL of RIF 600 mg, 70 mL of a silver-based aqueous solution (AG), or 50 mL of phosphate-buffered saline (PBS) over 15 minutes. Endografts were then retrieved from the sheath and cut in 1 × 1 cm sized graft units (n = 80 of each impregnation), which were then incubated for 1 hour separately with inoculates containing 10 or 10 bacteria per milliliter (bact/mL) of each of the following bacteria: multisensitive , and .

Objective/background: Debranching of the supra-aortic arteries is a common practice either as part of a hybrid treatment of aortic arch pathology or owing to arterial occlusive disease. Results of the debranching techniques have not been reported frequently.
Methods: This was a retrospective single centre study of all consecutive patients with cervical debranching procedures as part of hybrid aortic arch repair.

Background: The worldwide prevalence of peripheral artery disease (PAD) is increasing and endovascular revascularisation (ER) has become the primary invasive treatment option. This study aims to illuminate gender disparities in ER of PAD.
Methods: This is a retrospective, cross sectional study design.
Worldwide prevalence of peripheral artery disease (PAD) is increasing and peripheral vascular intervention (PVI) has become the primary invasive treatment. There is evidence that multidisciplinary team decision-making (MTD) has an impact on in-hospital outcomes. This study aims to depict practice patterns and time changes regarding MTD of different medical specialties.

Methods: A review of the Medline database was performed from 1997 to 2017 by a combined strategy of MeSh terms.
Results: The literature search identified 49 publications: 36 studies addressing prosthetic material infections and 13 studies addressing stent infections.
Purpose: To analyze the renal function and outcome after delayed (>6 hours) endovascular revascularization of acute renal artery occlusion (RAO) in patients with fenestrated-branched endovascular aneurysm repairs (EVARs) or open visceral debranching.
Methods: A single-center retrospective analysis was conducted involving 7 patients (mean age 61 years, range 49-72; 5 women) with 9 RAOs treated with endovascular revascularization between December 2014 and March 2017. Three patients had a solitary kidney with chronic renal insufficiency; 1 patient had bilateral occlusions as the acute event.
Incisional hernia is a frequent complication of midline laparotomy and enterostomal creation and is associated with high morbidity, decreased quality of life, and high costs. The International Symposium on Incisional Hernia Prevention was held October 19-20, 2017, at the InterContinental Hotel in San Francisco, CA, hosted by the Department of Surgery, University of California, San Francisco. One hundred and three attendees included general and plastic surgeons from 9 countries, including principal participants for several of the seminal studies in the field.

This systematic, multicentre, observational, cross-sectional study of adult patients with split-thickness skin graft (STSG) donor site wounds was conducted to evaluate quality of life (QoL) impairments caused by donor site wounds following split-thickness skin grafting. Therefore, 112 patients from 12 wound centres in Germany were examined based on patient and physician questionnaires as well as a physical examination of the donor site wound.

Patients experience substantial quality of life (QoL) impairments. The use of questionnaires for a continuous assessment of QoL and resulting interventions to improve the situation of the individual are an important cornerstone of a guideline-based wound care.

For infrarenal abdominal aortic aneurysm, the endovascular aortic repair has become a standard for elective and emergent cases. In complex abdominal or thoracoabdominal aortic pathologies, involving reno-visceral vessels, there are technical challenges for open and endovascular surgery.
View Article and Find Full Text PDFPurpose: To analyze the outcome of surgeon-modified fenestrated and branched stent-grafts (sm-FBSG) in high-risk patients with symptomatic complex aortic pathology or contained rupture.
Methods: A single-center retrospective analysis was conducted of 21 consecutive patients (mean age 70 years, range 58-87; 16 men) treated with a sm-FBSG from April 2014 to September 2016. The indications included 11 thoracoabdominal and 10 pararenal aortic pathologies, which presented as symptomatic in 8 and as contained rupture in 13 patients.
Purpose: To describe a hybrid technique of reversed frozen elephant trunk to treat thoracoabdominal aortic aneurysms (TAAA) through an abdominal only approach.
Technique: The technique is demonstrated in a 29-year-old Marfan patient with a chronic type B aortic dissection previously treated with a thoracic stent-graft who presented with a thoracoabdominal false lumen aneurysm. Through an open distal retroperitoneal approach to the abdominal aorta, a frozen elephant trunk graft was implanted over a super-stiff wire upside down with the stent-graft component in the thoracic aorta.
Purpose: To investigate the amount of gas released from Zenith thoracic stent-grafts using standard saline flushing vs the carbon dioxide flushing technique.
Methods: In an experimental bench setting, 20 thoracic stent-grafts were separated into 2 groups of 10 endografts. One group of grafts was flushed with 60 mL saline and the other group was flushed with carbon dioxide for 5 minutes followed by 60 mL saline.
Complex aortic aneurysms such as paravisceral aneurysm represent a challenging condition especially in the case of rupture. The presence of an aortoenteric fistula in this setting is associated with a very high mortality and morbidity. We report the case of a 72-year-old patient with contained ruptured paravisceral aortic aneurysm who underwent surgeon-modified fenestrated endovascular aneurysm repair (sm-fEVAR) with fenestrations for multiple renal arteries and the superior mesenteric artery.

Technique: The technique is described in a 55-year-old man with an enteric fistula involving an aortobi-iliac Y-prosthesis. After complete excision, the prosthesis was replaced by an allograft.
Background: Prolonged organ ischemia during complex aortic surgery is associated with increased morbidity and mortality. A novel hybrid graft (Gore Hybrid Vascular Graft) as composite of expanded polytetrafluorethylene vascular prosthesis that has a section reinforced with nitinol was investigated for feasibility and effectiveness during aortic repair.
Methods: Retrospective analysis of all consecutive patients treated with the hybrid vascular graft (HVG).
Purpose: To report a technique to create an extra-large vascular plug for occlusion of a large distal false lumen in chronic aortic dissection.
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.
