BACKGROUND: Biologic prosthesis (BP) has been reported as a safe alternative to polytetrafluoroethylene (PTFE) in vascular reconstruction. However, efficacy of BP remains controversial. We, therefore, conducted a systematic review to summarize previous available evidences comparing the BP and PTFE in terms of clinical outcomes. MATERIALS AND METHODS: A literature search of the MEDLINE and Scopus was performed to identify comparative studies reporting outcomes of BP, PTFE, and/or autologous veins graft (VG) in vascular access for hemodialysis or femoropopliteal bypass...

Lumbar total disc replacement (TDR) is an alternative to interbody fusion for the treatment of symptomatic degenerative disc disease. Traditionally, lumbar TDR is performed via an anterior retroperitoneal approach with regional risks of vascular and visceral injury. The direct lateral retroperitoneal, transpsoas approach avoids mobilisation of the great vessels and preserves the anterior longitudinal ligament, thereby maintaining physiological limits on motion. This study aimed to (i) report one site's early experience with lateral lumbar TDR and (ii) provide case examples illustrating the utility, complications and revision strategies of the XL-TDR device...

BACKGROUND: The postoperative occurrence of lymph fistulas in the groin is a complication that should be taken seriously. These fistulas cause an increase in morbidity and can support local and ascending infections. The treatment of this complication ranges from conservative procedures, such as compression dressings and bed rest to operative treatment with detection of the fistulas and ligation, negative pressure wound therapy (NPWT) or even muscle flaps. This review provides an overview of current therapeutic modalities...

Complex lesions of the thoracic aorta are traditionally treated in 2 surgical steps with the elephant trunk technique. A relatively new approach is the frozen elephant trunk (FET) technique, which potentially allows combined lesions of the thoracic aorta to be treated in a 1-stage procedure combining endovascular treatment with conventional surgery using a hybrid prosthesis. These are very complex and time-consuming operations, and good results can be obtained only if appropriate strategies for myocardial, cerebral, and visceral protection are adopted...

A 45-year-old man with Ebstein anomaly of the tricuspid valve, previously submitted for tricuspid valve replacement and plication of the atrialized part of the right ventricle, was referred because of signs of increased systemic venous pressure and low output symptoms. Clinical picture was due to severe prosthetic valve stenosis and significant paravalvular regurgitation across an aneurismal dilatation of the atrialized right ventricle. A combined transcatheter approach by Melody valve implantation and Amplatzer Vascular Plug occlusion of the paravalvular leak completely relieved the hemodynamic and clinical findings...

BACKGROUND: There are only a few options to replace infected infrainguinal synthetic vascular grafts in the absence of suitable autologous veins. To use a biosynthetic vascular graft (Omniflow(®)II) might be a valuable alternative. METHODS: We retrospectively analyzed the clinical course of 29 patients who underwent replacement of an infected infrainguinal vascular prosthesis (Szilagyi 3) by an Omniflow(®)II graft. RESULTS: Because of the lack of suitable autologous veins, 15 above-knee femoro-popliteal, 5 below-knee femoro-popliteal, and 9 femoro-tibial bypasses were replaced with biosynthetic grafts...

Three-dimensional (3D) printing is a rapidly advancing technology in the field of surgery. This article reviews its contemporary applications in 3 aspects of surgery, namely, surgical planning, implants and prostheses, and education and training. Three-dimensional printing technology can contribute to surgical planning by depicting precise personalized anatomy and thus a potential improvement in surgical outcome. For implants and prosthesis, the technology might overcome the limitations of conventional methods such as visual discrepancy from the recipient's body and unmatching anatomy...

We report a massive infected pseudoaneurysm of the right external iliac artery in the setting of Girdlestone pseudoarthroplasty (GSA) for chronic infection. Around the time of her GSA, the patient underwent cardiac catheterization with resultant pseudoaneurysm formation. Infection was likely due to spread from her previous chronic infection. Delay in presentation occurred due to attribution of her symptoms to her GSA. The patient underwent ligation of the right external iliac artery and hip disarticulation and was discharged on antibiotics...

Retroperitoneal sarcomas are rare malignant neoplasms that are often diagnosed late because of their typical nonspecific symptomatology. Radical surgical resection, if possible given the local anatomical conditions, is the most important treatment modality. However, even if the surgery is feasible and successful, the prognosis of retroperitoneal sarcoma is not good. The most frequent type of recurrence is local recurrence, and radical surgical resection remains the most important treatment modality even in such cases...

BACKGROUND: Patients with lower extremity amputation frequently suffer from socket-related problems. This seriously limits prosthesis use, level of activity and health-related quality of life (HRQoL). An additional problem in patients with lower extremity amputation are asymmetries in gait kinematics possibly accounting for back pain. Bone-anchored prostheses (BAPs) are a possible solution for socket-related problems. Knowledge concerning the level of function, activity and HRQoL after surgery is limited...
