Utility of the LigaSure vessel sealing system during major head and neck cancer surgery.
Summary of "Utility of the LigaSure vessel sealing system during major head and neck cancer surgery."
Objective:To evaluate the haemostatic efficacy and safety of the LigaSure vessel sealing system in major head and neck cancer surgery.Methods:This two-year, prospective study included 34 patients who underwent major head and neck cancer surgery at a university hospital. The LigaSure Precise handpiece and LigaSure 8 vessel sealing system were utilised as the primary means of haemostasis, except when sealing vessels larger than 7 mm in diameter. Surgical outcomes were evaluated. In addition, in each patient the diameter of the largest vein and artery sealed (all were >2 mm) was measured before sealing.Results:In all cases except one (33/34 patients), a sutureless technique was performed. Post-operative bleeding was observed in two cases. Thirty veins and 22 arteries were measured. The mean diameter of the largest sealed vein was 3.8 mm, while that of the largest sealed artery was 2.7 mm.Conclusion:Our experience indicates that the surgical technique described is safe and effective. The main advantages of the LigaSure system are that it simplifies the procedure and eliminates the need for clips and suture ligations.

Medical and Biotech [MESH] Definitions
Not an aneurysm but a well-defined collection of blood and CONNECTIVE TISSUE outside the wall of a blood vessel or the heart. It is the containment of a ruptured blood vessel or heart, such as sealing a rupture of the left ventricle. False aneurysm is formed by organized THROMBUS and HEMATOMA in surrounding tissue.
The neural systems which act on VASCULAR SMOOTH MUSCLE to control blood vessel diameter. The major neural control is through the sympathetic nervous system.
Enteric Nervous System
Two ganglionated neural plexuses in the gut wall which form one of the three major divisions of the autonomic nervous system. The enteric nervous system innervates the gastrointestinal tract, the pancreas, and the gallbladder. It contains sensory neurons, interneurons, and motor neurons. Thus the circuitry can autonomously sense the tension and the chemical environment in the gut and regulate blood vessel tone, motility, secretions, and fluid transport. The system is itself governed by the central nervous system and receives both parasympathetic and sympathetic innervation.

Femur Head Necrosis
Aseptic or avascular necrosis of the femoral head. The major types are idiopathic (primary), as a complication of fractures or dislocations, and LEGG-PERTHES DISEASE.
Vertebral Artery Dissection
Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.
