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…

Flap size as a confounding variable in flap perfusion measurement with the Oxygen-to-see (O2C) analysis system in microvascular head and neck reconstruction - a retrospective analysis.
[OBJECTIVES] The Oxygen-to-see (O2C) analysis system is used for flap monitoring based on predefined threshold values for flap perfusion. However, flap size may be a confounding variable. The aim of this study was to investigate the relatio…

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…

Impact of age on microvascular free flap perfusion in head and neck reconstruction.
[OBJECTIVE] Aging is associated with structural and functional cardiovascular changes that may affect microvascular free flap perfusion, which is a prerequisite for flap viability and flap success. This study is aimed to investigate the imp…

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…
-
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…
-
Identification of risk factors for postoperative delirium in patients following intraoral reconstruction with microvascular free flaps: a matched-pair analysis.
Postoperative delirium (POD) following microvascular head and neck reconstruction negatively impacts patient outcomes, and only a few risk factors have been identified. The aim of this study was to identify additional risk factors for POD a…

Smoking and microvascular free flap perfusion in head and neck reconstruction: radial free forearm flaps and anterolateral thigh flaps.
Head and neck reconstruction with microvascular free flaps is frequently performed in smokers. Smoking causes various alterations in the cardiovascular system. The aim of this study was to investigate the effects of smoking on flap perfusio…
