[Effectiveness of Mucosal Advancement Flaps in Surgery of Perianal Fistulas from Crohn´s Disease and Cryptoglandular Fistulas - a Long-term Follow-up Study].

Aim: Surgical treatment of perianal fistulae originating from Crohn's Disease (CD) or cryptoglandular abscess (CGA) remains a challenge. Data on long-term healing rates are scarce. We aimed to evaluate the long-term success rate of mucosal advancement flap (MAF) operations.

Outcomes of Candida and Non-Candida Aortic Graft Infection.

Objective: To evaluate and compare the outcomes of Candida- and non-Candida-associated aortic graft infections.

Methods: We retrospectively analyzed the data from patients treated for aortic graft infection from 2015 to 2021 in our hospital.

Results: A total of 66 patients (56 men; median age, 69 years; range, 50-87 years) were admitted with aortic graft infection, including 21 (32%) patients in the Candida group and 45 (68%) in the non-Candida group.

Neoaortoiliac system and cryopreserved human allograft for the treatment of aortic graft infections.

Objective: To report and compare neoaortoiliac system reconstruction and cryopreserved human allograft in treating aortic graft infections.

Methods: We retrospectively analysed the data of the patients treated for aorto graft infections between January 2015 and May 2021 in our hospital. The clinical data, diagnostic procedures, and surgical options were evaluated.

Outcomes of Endurant II Stent Graft According to Anatomic Severity Grade Score.

Objectives: This study's objective was to evaluate Endurant II (Medtronic Inc, Minneapolis, Minnesota) stent graft's early and midterm outcomes and compare the results according to the anatomic severity grade (ASG) scores.

Methods: This was a retrospective study of patients treated with the Endurant II stent graft between January 2013 and May 2021. The patients were divided into 2 independent groups, including those with a low ASG score (score <14) and a high ASG score (score >14).

Evaluation of Open Surgical and Endovascular Treatment Options for Visceral Artery Erosions after Pancreatitis and Pancreatic Surgery.

Purpose: To report and compare the results of endovascular and open surgical treatment for erosion bleeding of visceral arteries following pancreatitis and pancreatic surgery.

Materials And Methods: This retrospective study included 65 consecutive patients (46 males, mean age 63 ± 14 years) presenting with visceral artery erosions between January 2011 and December 2020. Endpoints were technical success, freedom from reintervention, stent-graft-related complications, and 30-day and one-year mortality.

Transcatheter Decellularized Tissue-Engineered Heart Valve (dTEHV) Grown on Polyglycolic Acid (PGA) Scaffold Coated with P4HB Shows Improved Functionality over 52 Weeks due to Polyether-Ether-Ketone (PEEK) Insert.

Many congenital heart defects and degenerative valve diseases require replacement of heart valves in children and young adults. Transcatheter xenografts degenerate over time. Tissue engineering might help to overcome this limitation by providing valves with ability for self-repair.

Computational modeling guides tissue-engineered heart valve design for long-term in vivo performance in a translational sheep model.

Valvular heart disease is a major cause of morbidity and mortality worldwide. Current heart valve prostheses have considerable clinical limitations due to their artificial, nonliving nature without regenerative capacity. To overcome these limitations, heart valve tissue engineering (TE) aiming to develop living, native-like heart valves with self-repair, remodeling, and regeneration capacity has been suggested as next-generation technology.
