Confounding effects of blood hemoglobin and hematocrit levels on flap perfusion measurement with the Oxygen-to-see (O2C) analysis system in microvascular head and neck reconstruction- a retrospective study.
[BACKGROUND] The Oxygen-2-see (O2C) analysis system can measure flap perfusion, which is a prerequisite for flap viability, and it is therefore commonly used in flap monitoring for microvascular head and neck reconstruction. However, in the…

Continuous Measurement of Radial Free Forearm Flap Tissue Perfusion for Flap Monitoring After Microvascular Head and Neck Reconstruction-Systemic Blood Pressure as a Potential Confounder in the Early Postoperative Period.
Continuous measurement of flap tissue perfusion in the context of postoperative flap monitoring after microvascular head and neck reconstruction may be confounded by alterations in systemic blood pressure, particularly when using predefined…
-
Blood pressure and microvascular free flap perfusion in head and neck reconstruction- a retrospective analysis.
[PURPOSE] The influence of blood pressure on microvascular free flap perfusion is not fully understood and remains an ongoing topic of debate, as flap perfusion is both a prerequisite for flap viability and a parameter frequently used for p…

Impact of Vasopressors on Microvascular Free Flap Perfusion in Head and Neck Reconstruction.
[INTRODUCTION] The use of vasopressors in microvascular head and neck reconstruction is still controversial in view of its potentially negative influence on microvascular flap perfusion, which is crucial for flap viability and commonly used…

Free Flap Perfusion in Microvascular Head and Neck Reconstruction: Influence of the Number of Ischemia Intervals and Ischemia Duration-A Retrospective Study.
[BACKGROUND] In microvascular head and neck reconstruction, ischemia of the free flap tissue is inevitable during microsurgical anastomosis and may affect microvascular free flap perfusion, which is a prerequisite for flap viability and a p…

Tensile strength of adhesives in peripheral nerve anastomoses: an in vitro biomechanical evaluation of four different neurorrhaphies.
[BACKGROUND] The fundamental prerequisite for prognostically favorable postoperative results of peripheral nerve repair is stable neurorrhaphy without interruption and gap formation. [METHODS] This study evaluates 60 neurorrhaphies on femo…

Does the Anastomosis Recipient Vessel Have an Influence on Free Flap Perfusion in Microvascular Head and Neck Reconstruction-A Retrospective Analysis of 338 Cases with Comparison of Flap Perfusion between Different Arterial and Venous Recipient Vessels in Radial Free Forearm Flaps, Anterolateral Thigh Flaps, and Fibula Free Flaps.
Flap perfusion is a prerequisite for microvascular free flap survival and a parameter routinely used for flap monitoring. The aim of this study was to investigate the influence of the anastomosis recipient vessel on flap perfusion. Flap pe…

Perfusion of microvascular free flaps in head and neck reconstruction after prior neck dissection and irradiation.
Microvascular free flaps are frequently used for head and neck reconstruction after prior neck dissection (ND) and neck irradiation (RTX). The aim of this study was to investigate the influence of ND and RTX on flap perfusion as a critical …
-
Impacts of vascular comorbidities on free flap perfusion in microvascular head and neck reconstruction.
[PURPOSE] Arterial hypertension (AHTN), type 2 diabetes mellitus (DM), and atherosclerotic vascular disease (ASVD) are common vascular comorbidities in patients undergoing reconstruction of the head and neck region with a microvascular free…

Flap perfusion monitoring with an attached surface probe in microvascular reconstruction of the oral cavity.
[OBJECTIVES] Postoperative flap monitoring is essential in oral microvascular reconstruction for timely detection of vascular compromise. This study investigated the use of attached surface probes for the oxygen-2-see (O2C) analysis system …
-
Influence of perioperative blood pressure regulation on postoperative delirium in patients undergoing head and neck free flap reconstruction.
[BACKGROUND] Postoperative delirium (POD) is a serious complication in patients undergoing microvascular head and neck reconstruction. Whether intraoperative and postoperative blood pressure regulation are risk factors for POD remains uncle…
-
Attached compared with unattached surface probes for monitoring flap perfusion in microvascular head and neck reconstruction: a feasibility study.
Unattached surface probes are commonly used with the O2C analysis system (LEA Medizintechnik, Germany) to monitor microvascular free flap perfusion. This study compared attached and unattached surface probes for extraoral free flaps. The st…

Biodegradation and Immunological Parameters of Polyurethane-Based Tissue Adhesive in Arterial Microvascular Anastomoses-A Long-Term In Vivo Study.
In microsurgical anastomosis, non-synthetic fibrin-based adhesives have predominantly shown superior properties to synthetic cyanoacrylates, but they have hardly any clinical application. This study aims to investigate the local and systemi…
