T e frst successful renal transplant was done by Dr Joseph Murray in 1954 with kidney donated by the twin brother to his sibling who was in renal failure. With the advent of newer and better drugs for immunosuppression, there has been no looking back. Declining renal function leads to chronic renal failure and a stage comes when renal replacement therapy becomes mandatory. At this stage, the renal function is generally less than 10–15% of the normal functioning kidneys. T e maintenance dialysis therapy is not only a cumbersome costly option for the patients but also has been found to have a lower survival beneft as compared to renal transplant. A signifcant reduction in mortality was shown in renal transplant recipients as compared to ones on waiting list and those on dialysis. In the deceased donor the organ are retrieved from brain dead patients with intact circulation. To increase the donor pool, there has been a shift in obtaining organs from non heart beating donor as well.
The posterior auricular artery arises from the back of the external carotid just above the level at which the latter is crossed by the posterior belly of the digastric muscle cheap ramipril 10mg line arrhythmia and murmur. The superficial temporal artery and the maxillary artery are terminal branches of the external carotid ar- tery discount ramipril online amex hypertension exercise. They begin behind the neck of the mandible purchase ramipril with amex hypertension icd 9, in the substance of the parotid gland buy 5mg ramipril otc arteria circumflexa femoris lateralis. The ascending pharyngeal artery runs upwards to the base of the skull, lying between the pharynx and the internal carotid artery. The superior thyroid artery runs downwards and medially to reach the upper pole of the thyroid gland. The terminal part of the anterior branch runs across the upper part of the isthmus of the gland to anastomose with the artery of the opposite side. The posterior branch runs downwards along the posterior border of the thyroid to anastomose with the inferior thyroid artery. The lingual artery arises from the external carotid artery opposite the tip of the greater cornu of the hyoid bone (42. The first part of the artery lies in the carotid triangle, superficial to the middle constrictor of the pharynx (42. The second part of the artery lies deep to the hyoglossus muscle that separates the artery from the hypoglossal nerve. The third or deep part of the artery runs upwards along the anterior margin of the hyoglossus; and then forwards to the tip of the tongue. The facial artery arises from the external carotid just above the greater cornu of the hyoid bone (42. The artery first runs upwards along the posterior border of the gland and then downwards and forwards between the gland (deep to it) and the medial pterygoid muscle (superficial to it) (42. It reaches the lower border of the mandible at the anterior edge of the masseter (42. Curving round this border the artery runs upwards and forwards across the superficial aspect of the body of the mandible, and across the buccinator muscle to reach the angle of the mouth. It then runs upwards along the side of the nose to reach the medial angle of the palpebral fissure. The tonsillar branch reaches the tonsil by piercing the superior constrictor muscle. The submental artery runs forwards along the lower border of the mandible (over the mylohyoid muscle). This artery arises from the posterior aspect of the external carotid opposite the origin of the facial artery. It runs backwards along the lower border of the posterior belly of the digastric muscle (42. Here, it lies deep to the sternocleidomastoid, the digastric and some other muscles. It then runs medially, and becoming superficial supplies the posterior part of the scalp. The stylomastoid branch enters the stylomastoid foramen to supply the middle ear and related structures. Meningeal branches enter the skull through the jugular foramen and the carotid canal. A deep branch which anastomoses with branches of the vertebral and deep cervical arteries. This artery arises from the external carotid just above the posterior belly of the digastric muscle (and stylohyoid muscle).

The images produced are degraded to some extent by blurring caused by interfering absorption on either side of the the basic design for a modern transaxial tomographic plane of interest order ramipril 2.5mg arrhythmia nodosum. The X-ray tube and detectors 510 mm % are fixed together as a single rotating unit discount 5 mg ramipril overnight delivery blood pressure sounds. The fan arrangement is projections completing a 360° sweep (360 projection rotated in a series of projections or angles covering 1° per projection; 720 projections 0 cheap generic ramipril uk heart attack party tribute to trey songz. The typical side patient slice during its 360° rotation; these are stored projection for a fan beam construction cheap 10mg ramipril with mastercard hypertension kidney, with anode in computer memory as a data matrix or attenuation alignment, collimators, and detector array is shown values. The transaxial image is formed by calculat- scan movement (translation) for their data acquisi- ing individual values within the matrix using tion, which was very slow: these were the first and image reconstruction techniques. Third generation complete digital matrix whose elements represent machines use fan beam rotate only designs and have the individual linear attenuation coefficients for the very fast data acquisition times; approximately 1 to 2 s section or slice in the plane of the X-ray beam. Image data is obtained by rotat- fundamental mathematics involved was first pre- ing the fan beam around the patient in a series of sented by J. Basic sequential scanner design 383 the major drawback of early fan beam designs was 0° that the X-ray tube had to return to its starting (home) position after each rotation; high voltage cable and sig- nal leads connected to the rotating mechanism make this essential. A total of 500 projections are sufficient for a Detector array 256 256 matrix with 1 mm resolution whereas (a) 1000 projections require a 512 512 matrix to see 0. The X-ray beam is highly filtered by both 1,3 2,3 3,3 4,3 5,3 beam 3 aluminum and copper to produce a high effective ?1,4 ?2,4 ?3,4 ?4,4 ?5,4 photon energy. The X-ray intensity or output must not vary over (b) Ray-sum 1 the image acquisition cycle as any variation would be treated as absorption differences in the image; gener- Figure 14. The linear showing construction of matrix cells during fan-beam attenuation coefficient is dependent on the kilo- rotation. In addi- tion it is necessary to maintain the X-ray spectrum to within very narrow limits so that does not alter. This small movement effectively halves the order to generate the necessary minimum number of detector width for a given number of fan beam projec- X-ray photons. As the focal spot increases the current and voltages controlled by a dedicated micro- point information is spread over a larger number of processor. This is at least 50% Modern machines using a continuously rotating higher than conventional radiography and extra beam fan beam design can also switch the position of the filtration (2. This has the effect of doubling the ensures that the effective energy is also high (70 to number of projections during a scan. This reduces the effect of ‘beam hardening’ the electron beam in the X-ray tube is magnetically by the tissues. Subject contrast of soft-tissue detail from this high effective energy does not depend on photoelectric X-ray tube absorption (in common with most conventional anode radiography) but the dominant interaction is due to Fs A Fs B inelastic or Compton scattering which removes X-ray photons from the main beam. Since the fan-beam system has a narrow, highly collimated X-ray source and the detector array is also carefully collimated, the amount of scattered radiation that reaches the detec- tors is minimized so the image information is carried by the emerging unscattered X-ray beam. Photoelectric absorption is dependent on atomic Detector array number Z and density but Compton scattering depends on tissue electron density (see Chapter 5). Although the electron density per gram of soft tissue is very Reading from Fs A consistent over a fixed volume of tissue the electrons per unit volume (electrons cm 3) does vary. This allows double sampling of the detector lower energy photons are preferentially removed; the which yields two offset readings A and B. The increase in effective energy causes tions work well for soft tissue (water equivalent) but beam hardening which is influenced by the patient problems can occur in images containing a large thickness and tissue material; it is worse for bone. In order to mini- Absorption of a monochromatic X-ray beam with mize beam hardening it is heavily filtered, using 0. A high resolution in the slice plane in out can only be achieved if it is matched by a thin slice, so resolution should be balanced between the slice plane and slice thickness. Owing to the finite length of the Polychromatic detector and the small dimensions of the focal spot, X-ray beam the X-ray beam diverges somewhat in the direction of the slice thickness, so that the latter acquires a slightly wedge shape.
