Outcomes of Omniflow® II prosthesis used for revascularization in the femoral tract both in infected and non-infected setting.

Background: Evidence regarding the outcomes of Omniflow II prosthesis in peripheral arterial revascularization at different anatomical sites and for different indications is scarce. Therefore, the aim of this study was to evaluate the outcomes of the Omniflow II used at various positions within the femoral tract both in infected and non-infected setting.

Methods: Patients who underwent reconstructive lower leg vascular surgery with implantation of an Omniflow II from 2014 until 2021 at five medical centers were retrospectively included (N.

Use of Omniflow® II Biosynthetic Graft for the Treatment of Vascular Graft and Endograft Infections.

Background: Vascular graft/endograft infection is a rare but life-threatening complication of cardiovascular surgery and remains a surgical challenge. Several different graft materials are available for the treatment of vascular graft/endograft infection, each having its own advantages and disadvantages. Biosynthetic vascular grafts have shown low reinfection rates and could be a potential second best after autologous veins in the treatment of vascular graft/endograft infection.

Lymphatic drainage patterns from melanomas on the shoulder or upper trunk to cervical lymph nodes and implications for the extent of neck dissection.

Purpose: To determine the incidence and pattern of cervical lymphatic drainage in patients with melanomas located on the upper limb or trunk, and to evaluate our current neck dissection protocol for those patients with a N+ neck.

Methods: Of 1192 melanoma patients who underwent sentinel node biopsy, 631 were selected with a primary tumor on the upper limb or trunk. All lymphoscintigrams, SPECT/CT images and operative reports were reviewed to determine the exact locations of sentinel nodes visualized preoperatively and dissected during operation.
