  • resection
  • The introduction of endscopic submucosal dissection (ESD) has enabled the en bloc resection of large lesions, lesions with scar formation, and lesions formed on intestinal folds, which could not be resected en bloc by the conventional endoscopic mucosal resection (EMR) technique [ 1 , 2 ].

  • 1997
  • Despite a number of lineup changes, Dissection released The Somberlain in 1993 and Storm of the Light's Bane in 1995, before splitting up in 1997 due to Nödtveidt's imprisonment for complicity in the murder of Josef Meddour. (wikipedia.org)
  • geometry
  • In geometry, a dissection problem is the problem of partitioning a geometric figure (such as a polytope or ball) into smaller pieces that may be rearranged into a new figure of equal content. (wikipedia.org)
  • Hilbert's
  • This proof holds even under the assumption that the pieces may not overlap while swinging, and can be generalised to any pair of three-dimensional figures which have a common dissection (see Hilbert's third problem). (wikipedia.org)

  • tear
  • In medical pathology, a dissection is a tear within the wall of a blood vessel, which allows blood to separate the wall layers. (wikipedia.org)
  • An aortic dissection -- also referred to as dissecting aorta or dissecting aneurysm -- occurs when the inner layer of the aorta tears and blood is channeled through the tear, causing the inner and middle layers to separate. (uchospitals.edu)
  • organs
  • This technique allows a body to be sent to a funeral director without waiting for the sometimes time-consuming dissection of individual organs. (wikipedia.org)
  • Dissections become threatening to the health of the organism when growth of the false lumen prevents perfusion of the true lumen and the end organs perfused by the true lumen. (wikipedia.org)
  • Similarly, vessels and organs perfused from the true lumen but distal to the dissection may be perfused to varying degrees. (wikipedia.org)
  • neck
  • However, neck dissection is rarely performed for such purposes. (wikipedia.org)
  • As such the neck dissection is the en-bloc resection of all soft tissue in the region including all the lymph nodes and structures passing through them. (wikipedia.org)
  • In the case of a neck dissection, this entails the resection of everything within the superficial layer of deep cervical fascia (also known as the investing layer of cervical fascia). (wikipedia.org)
  • 1906 - George W. Crile of the Cleveland Clinic describes the radical neck dissection. (wikipedia.org)
  • 1957 - Hayes Martin describes routine use of the radical neck dissection for control of neck metastases. (wikipedia.org)
  • To describe the lymph nodes of the neck for neck dissection, the neck is divided into 6 areas called Levels. (wikipedia.org)
  • Vertebral dissection may occur after physical trauma to the neck, such as a blunt injury (e.g. traffic collision), strangulation or manipulation, but may also happen spontaneously. (wikipedia.org)
  • geometric
  • A hinged dissection, also known as a swing-hinged dissection or Dudeney dissection, is a kind of geometric dissection in which all of the pieces are connected into a chain by "hinged" points, such that the rearrangement from one figure to another can be carried out by swinging the chain continuously, without severing any of the connections. (wikipedia.org)
  • A dissection puzzle, also called a transformation puzzle or Richter Puzzle, is a tiling puzzle where a set of pieces can be assembled in different ways to produce two or more distinct geometric shapes. (wikipedia.org)
  • Dissection puzzles are an early form of geometric puzzle. (wikipedia.org)
  • In the 10th century, Arabic mathematicians used geometric dissections in their commentaries on Euclid's Elements. (wikipedia.org)
  • Since then, dissection puzzles have been used for entertainment and maths education, and creation of complex dissection puzzles is considered an exercise of geometric principles by mathematicians and math students. (wikipedia.org)
  • The dissections of regular polygons and other simple geometric shapes into another such shape was the subject of Martin Gardner's November 1961 "Mathematical Games column" in Scientific American. (wikipedia.org)
  • Other dissections are intended to move between a pair of geometric shapes, such as a triangle to a square, or a square to a five-pointed star. (wikipedia.org)
  • intimal
  • An estimated 0.67% of patients admitted to the hospital after major motor vehicle accidents were found to have blunt carotid injury, including intimal dissections, pseudoaneurysms, thromboses, or fistulas. (wikipedia.org)
  • Tears in the intimal layer result in the propagation of dissection (proximally or distally) secondary to blood entering the intima-media space. (medscape.com)
  • arterial
  • The stenosis that occurs in the early stages of arterial dissection is a dynamic process and some occlusions can return to stenosis very quickly. (wikipedia.org)
  • 70% of patients with carotid arterial dissection are between the ages of 35 and 50, with a mean age of 47 years. (wikipedia.org)
  • FAD is thought to be passed down as an autosomal dominant disease and once inherited will result in dissection of the aorta, and dissecting aneurysm of the aorta, or rarely aortic or arterial dilation at a young age. (wikipedia.org)
  • stroke
  • Neurological complications of aortic dissection (i.e., stroke and paralysis) are due to the involvement of one or more arteries supplying portions of the central nervous system. (wikipedia.org)
  • practice
  • The practice of dissection flourished during the 7th and 8th century. (wikipedia.org)
  • Blunt dissection is contrasted to sharp dissection, the practice of slicing through tissues with scalpels, scissors, electrosurgery, or other advanced technologies usually employing heat. (wikipedia.org)
  • Sentinel lymph node biopsy for breast cancer: a suitable alternative to routine axillary dissection in multi-institutional practice when optimal technique is used. (springer.com)
  • internal
  • Following incision above the rib (to avoid the neurovascular bundle), blunt dissection of the subcutaneous tissue, external, internal and innermost intercostal muscles allows access to the pleura. (wikipedia.org)
  • hinge
  • A twist-hinge dissection is one which use a three-dimensional "hinge" which is placed on the edges of pieces rather than their vertices, allowing them to be "flipped" three-dimensionally. (wikipedia.org)
  • Creators of new dissection puzzles emphasize using a minimum number of pieces, or creating novel situations, such as ensuring that every piece connects to another with a hinge. (wikipedia.org)
  • chest
  • Indeed, blunt dissection is now considered the favoured approach for the insertion of large bore chest tubes since it results in fewer complications. (wikipedia.org)
  • Swedish
  • Dissection was a Swedish extreme metal band from Strömstad, formed in 1989 by guitarist, vocalist and main songwriter Jon Nödtveidt and bass guitarist Peter Palmdahl. (wikipedia.org)
  • signs
  • While the pain may be confused with the pain of a myocardial infarction (heart attack), aortic dissection is usually not associated with the other signs that suggest myocardial infarction, including heart failure and ECG changes. (wikipedia.org)
  • indicate
  • Unfortunately, there is little that remains from this time to indicate whether or not dissection occurred, the civilization was lost to the Aryan people invading. (wikipedia.org)
  • ischemic
  • Hospital-based series suggest that cervicocephalic dissections are responsible for 1-2.5% of ischemic strokes in the general population and for 5-20% of strokes in individuals younger than 45 years. (medscape.com)
  • surgery
  • Surgery is usually required for dissections that involve the first part of the aorta, while those that do not can typically be treated with blood pressure and heart-rate lowering unless complications result. (wikipedia.org)
  • Surgery for aortic dissection was introduced in the 1950s by Michael E. DeBakey. (wikipedia.org)
