Noncontact diffuse optical assessment of blood flow changes in head and neck free tissue transfer flaps.
Knowledge of tissue blood flow (BF) changes after free tissue transfer may enable surgeons to predict the failure of flap thrombosis at an early stage. This study used our recently developed noncontact diffuse correlation spectroscopy to monitor dynamic BF changes in free flaps without getting in contact with the targeted tissue. Eight free flaps were elevated in patients with head and neck can...
متن کاملRelationship between flow and incidence of thrombosis in polytetrafluoroethylene vascular grafts in free microvascular flaps in lambs.
We have done an experimental study in lambs in which we investigated the influence of flow rate on free microvascular flaps using polytetrafluoroethylene (PTFE) vascular grafts. We set up five surgical groups in which blood flow was progressively increased through the PTFE vascular graft. In group I (venous autograft) we observed just one vascular thrombosis which was located at the site of the...
متن کاملSuperb Micro-Vascular Imaging (SMI) in the analysis of fetoplacental microvascular blood flow
F Introduction Ultrasound monitoring of pregnancy is based on standardised 2D examination of the fetus and associated structures in each trimester of pregnancy. A second-look ultrasound examination is undertaken for diagnostic or prognostic purposes in various circumstances: localisation of a suspected morphological or biometric abnormality found on the screening ultrasound and/or identificatio...
متن کاملPerforator Relocation in Free Style Local Perforator Flaps
Local perforator flaps have evolved over the time to provide complete and stable coverage of soft tissue defects. Technical advances and experience with the perforator flaps have allowed the harvest of local perforator flaps in a free style manner by offering greater freedom in flap selection. We have proposed a technical modification in the harvest of a perforator flap by relo-cating the perfo...
متن کاملBlood Flow and Vascular Inflammation
Atherosclerosis is characterized by an accumulation of smooth muscle cells and a buildup of lipid-rich foamy macrophages within the arterial wall, which can lead to lumen narrowing and reduced blood flow or to a complete arterial blockage after plaque rupture. Atherosclerosis development is influenced by several factors, including age, sex, cholesterol level, and obesity. Despite the systemic n...
