microvasular surgery

Head and neck carcinoma can prompt destroying cosmetic and functional deformities with resultant mental, physical and nourishing burden. Regardless of ongoing advances in medication and surgical procedure, the general endurance for patients with head and neck malignant growth has stayed still for as long as 35 years. This endurance rate has prompted the foundation of the standards of tumor extraction with most extreme tissue saving and more up to date endoscopic laser-helped methods for auto-digestive region malignant growths targeting diminishing operational morbidity without influencing the general endurance...

BACKGROUND: Intraoperative semiquantitative classification of different visible 5-aminolevulinic (5-ALA) fluorescence levels by the neurosurgeon is subjective. Recently, handheld spectroscopic probes were introduced enabling quantitative analysis of 5-ALA induced fluorescence intensity (FI). The aim of this ex-vivo study was to correlate the FI in gliomas of different grades with histopathology, proliferation and microvasular density (MVD). PATIENTS AND METHODS: Patients with suspected World Health Organization (WHO) grade II-IV gliomas were included and tissue samples from different visible fluorescence levels (strong, vague or none) were intraoperatively collected...

The perfection of micro-suture of small vessels has enabled trnasplantation of various large composite tissues by anastomosing their nutrient vessels directly to suitable vessels in the recipient site. Among them, the so-called free skin flap has many advantages over the conventional flap methods for covering the complicated defects of the skin and subcutaneous tissues. In this paper, the author introduces the representative free skin flaps on the basis of his 300 clinical free flap experiences.
