If the kidneys are to be separated, the left renal vein is transected flush at its entrance into the inferior vena cava Fig. A, Placement of kidneys in an ice basin. B, Division of kidneys using a posterior approach to split the aorta. For division of the kidneys for slush preservation, it is safest and most convenient Cadaverica Receptia (Basic Protocol And Procedure On Cadaver Reception With Organ Removal) - Infester (2) - The Autopsy Findings Archive (2007-2014) Vol.
1 (CDr) turn the specimen over Fig. With one blade of a scissors inserted into its lumen, the posterior wall of the aorta is incised. A perfect guide to the line of aortic incision is the row of ligated or clipped lumbar arteries Fib. Then, with a perfect internal view of the renal arterial branches passing laterally, the anterior wall of the aorta is incised longitudinally from the inside Fig. If a perfusion is planned, aortic flaps are fashioned during separation and used for closure so that cannulas need not be placed directly into the renal arteries.
If the left renal vein was detached from the vena cava as described earlier, it is perfectly safe to divide quickly the remaining structures connecting the right and left kidneys. After the kidneys or other organs, or both, have been cooled and excised, segments of the iliac arteries and veins are routinely removed Fig. The thoracic aorta and pulmonary artery may also be taken.
Such grafts can be life-saving in the event of unexpected technical problems in the recipient 7. Removal of segments of iliac arteries and veins and thoracic aorta. The vascular grafts are refrigerated and kept in case of an emergency.
Removal of the liver requires only minor modifications of the foregoing basic technique. As soon as the midline incision is made, the liver is inspected to be sure that its color and texture are normal.
Anomalies are looked for, of which arteries to the left lobe from the left gastric artery or to the right lobe from the superior mesenteric artery are the most frequent.
Ways of dealing with such anomalies have been described else-where 89 and will not be considered herein. If the anatomy is normal, the splenic and left gastric arteries are dissected, ligated and divided Fig. The aorta is encircled at one of the locations above the celiac axis as was described in the section on graft nephrectomy Fig. Hepatectomy hilar dissection and transection of the common bile duct as an initial step in multiple organ harvesting.
Note that the splenic vein or alternatively the superior mesenteric vein is cannulated for eventual delivery of preservation fluid. Turning more distally, the gastroduodenal artery and, when present, the right gastric artery are ligated and divided. Beneath the gastroduodenal artery is found the portal vein Fig. The common bile duct is mobilized to as low a level as possible and transected Fig.
At the same time, the gallbladder is incised and bile is washed out in order to prevent autolysis of the mucosa of the biliary tract. The portal vein is cleaned inferiorly to the junction of the splenic vein and the superior mesenteric vein. The superior mesenteric vein is encircled. If necessary for exposure, the neck of the pancreas should be divided. Next, the distal part of the abdominal aorta and inferior vena cava are freed and ligated as described in the section on graft nephrectomy Fig.
Aortic and vena caval cannulas are placed after systemic heparinization. In adults, the liver can be felt to cool after 1 or 2 liters of infusion at the same time as the body temperature falls. At this time, the previously encircled superior mesenteric artery Fig.
Over infusion is prevented by intermittent bleeding off through the inferior vena cava cannula. The circulation of the donor is still intact and the progressively cooling liver still has an hepatic arterial supply.
In situ infusion technique used when the kidneys and liver are removed from the same donor. Procurement is terminated as with graft nephrectomy by cross clamping the aorta near the diaphragm at one of the sites of its previous encirclement Fig. Cold solution through the aortic cannula is immediately infused as with graft nephrectomy, and blood from the inferior vena cava is drained onto the floor bag.
The right atrium is also opened as an extra precaution against overdistention of the liver. Anesthesiologic support is stopped. The celiac axis is detached from the aorta with an aortic patch or taken in continuity with the full aortic circumference. If further renal cooling is desired, the donor aorta can be clamped just below the celiac axis.
Until this time, dissection of the suprahepatic vena cava has been avoided. Now, the suprahepatic vena cava is dissected free along with the surrounding cuff of diaphragm. The liver is peeled inferiorly cutting posterior attachments, including the right adrenal veins Fig.
No unusual effort is made to tie individual tributaries to the vena cava at any level since this can be done later at leisure in an ice basin in the recipient operating room after the specimen has been returned to the parent hospital. Since the celiac axis has already been cut free in continuity with a circumferential piece of aorta or an aortic patch, the liver is ready for removal.
The freed liver is taken to a back table, given a final flush in adults with or milliliters of cold Collins type solution and placed in a bag which is filled with the same kind of solution. The bag is sealed and covered with crushed ice in a picnic cooler. The ten or 15 minutes required to remove the liver is not harmful to the kidneys which are not subjected to any warm ischemia whatsoever.
With the liver out, removal of the kidneys en bloc is carried out as described in the section on graft nephrectomy. The excision is greatly facilitated by the absence of the liver. Vascular grafts are removed as described previously. The simple preparatory steps described previously are completed.

1 (CDr). The principle that is followed is to disconnect the thoracic and abdominal aortic circulation by aortic cross clamping at one of the encirclement levels just above or below the diaphragm Fig.
The preparation for this technical step is the aortic dissection previously described in the section on graft nephrectomy Fig. Final steps if the heart is to be removed in combination with nephrectomies or hepatectomy, or both. See text for details. Before this final step is taken, the pericardium is incised, and the aortic root is separated from the main pulmonary artery.
The superior vena cava is stapled 2 centimeters proximal to its junction with the right atrium, the inferior vena cava is clamped or incised Fig. At the same time as the aorta is cross clamped at the diaphragm, the thoracic aortic arch is clamped at the origin of the innominate artery. Chilled electrolyte solution is infused into both the aortic root Fig. An improved embalming procedure for long-lasting preservation of the cadaver for anatomical study.

H Rodrigues Related Papers. The UNOS database does not provide information pertaining to the development of hepatitis in recipients in either group, but there are data on mortality in recipients of transplants from donors with positive HBV serology.
Because HBsAg-negative, anti-HBc-positive donors can transmit HBV to renal allograft recipients [ 10 ], perhaps the most appropriate use of kidneys obtained from cadaver donors whose serological results reveal isolated anti-HBc reactivity is transplantation to recipients who have been immunized to HBV or who have an extenuating need table 4. In the study by Satterthwaite et al. Antibody to hepatitis B core antigen anti-HBc status 1 year after transplantation, compared with donor anti-HBc status for heart and kidney transplant recipients who were anti-HBc-negative at the time of transplantation.
Suggested thoracic and renal candidates for a transplant from a donor with isolated antibody to hepatitis B core antigen anti-HB positivity. Prophylactic treatment with hepatitis Cadaverica Receptia (Basic Protocol And Procedure On Cadaver Reception With Organ Removal) - Infester (2) - The Autopsy Findings Archive (2007-2014) Vol. 1 (CDr) immune globulin would be a useful adjunct to prevent the development of hepatitis in allograft recipients who have not been immunized to HBV; lamivudine treatment should be reserved for those who develop hepatitis after transplantation [ 11 ].
The hazard of HCV transmission from Cadaverica Receptia (Basic Protocol And Procedure On Cadaver Reception With Organ Removal) - Infester (2) - The Autopsy Findings Archive (2007-2014) Vol. 1 (CDr) previously infected organ donor is a concern for all allograft recipients. IgG antibody to HCV does not protect against donor organ contamination; however, it is also important to emphasize that detection of antibody to HCV by serological screening of the donor is not predictive of HCV transmission [ 15 ].
Unfortunately, the use of PCR testing cannot be accomplished within the time constraint of the preservation period necessary for the release of the donor organs. Thus, exclusion of all organ donors positive for antibody to HCV would eliminate the possibility of HCV transmission; however, such an indiscriminate policy would unnecessarily discard some organs that are not infected with HCV.
The transmission of HCV through a kidney transplant may be affected by the method of preservation. Roth et al. The following data were derived from analyses of data on cadaver heart and kidney transplantations from the UNOS database that were performed from 1 April through 30 June ; the analyses assessed the outcome of HCV-negative recipients of transplants from donors positive for antibody to HCV table 5.
Antibody to hepatitis C virus anti-HCV status 1 year after transplantation, by donor anti-HCV status for heart and kidney transplant recipients who were anti-HCV-negative at the time of transplantation. However, notwithstanding the high risk of transmission of HCV to allograft recipients, a positive screening result does not necessarily rule out organ donation [ 16 ]. Fishman et al. However, transplantation of a liver from a donor positive for antibody to HCV to a recipient positive for antibody to HCV does not appear to cause increased morbidity or mortality [ 19 ].
Transplantation of an HCV-positive heart allograft when a HCV-negative recipient's life is in danger may be the only alternative to immediate death. The seminal work of Ho et al. More than 2 decades later, CMV disease remains a major complication of organ transplantation.
The development of CMV disease has been associated with increased morbidity and cost of transplantation, because of an increased risk of organ rejection, allograft loss, and death [ 22 Cadaverica Receptia (Basic Protocol And Procedure On Cadaver Reception With Organ Removal) - Infester (2) - The Autopsy Findings Archive (2007-2014) Vol. 1 (CDr). Thus, all prospective organ donors and recipients should be routinely tested for antibody to CMV.
Transplantation of an organ from a CMV-positive donor can result in subsequent reactivation of latent virus and replication in the immunosuppressed host. The specific CMV serological status of the donor and recipient has implications for prophylaxis, the highest risk group being CMV-seronegative recipients of CMV-seropositive donor organs i.
Nevertheless, transplantation of organs from CMV-seropositive donors has not been considered an absolute contraindication for transplantation [ 23 ], because the high seroprevalence of the virus among the general population Cadaverica Receptia (Basic Protocol And Procedure On Cadaver Reception With Organ Removal) - Infester (2) - The Autopsy Findings Archive (2007-2014) Vol.
1 (CDr) it impractical to rule out such donors. Furthermore, recent evidence suggests that even mismatches between CMV-positive donors and CMV-negative recipients can be successfully overcome by strategies aimed at prophylaxis for CMV infection. Treatment with valacyclovir after renal transplantation has reduced the incidence or delayed the onset of CMV disease in both seronegative and seropositive patients [ 24 ].
Treatment with valacyclovir has also decreased the rates of CMV viremia and viruria and herpes simplex virus disease [ 24 ]. From a practical standpoint, donor testing for CMV should always be performed before any blood or plasma product transfusion to an organ donor. Furthermore, testing after donor transfusion also introduces the possibility of a false-positive result of CMV for organ donors, because of antibody to CMV that is passively transmitted in the blood products.
HHV-8 has been detected in all forms of Kaposi's sarcoma, including transplantation-associated Kaposi's sarcoma. Regamey et al. Within the first year after transplantation, seroconversion was detected in 25 patients.
Kaposi's sarcoma developed in 2 of them within 26 months after transplantation. Of 8 controls who were seronegative at the time of transplantation and received allografts from HHVnegative donorsnone underwent seroconversion within 1 year after transplantation. Thus, HHV-8 has been transmitted through renal allografts, and it is a risk factor for transplantation-associated Kaposi's sarcoma.
Nevertheless, the unusual occurrence of Kaposi's sarcoma in the transplant recipient makes routine screening of all cadaver donors for HHV-8 impractical. Transmission of other neurotropic viruses, such as rabies virus and the agent of Creutzfeldt-Jacob disease, from tissue donors has been reported [ 26 ]. Donor deaths associated with these viruses exclude such a donor from consideration. Although successful transplantation of renal allografts from donors with Reye's syndrome encephalopathy and liver failure was reported several years ago [ 27 ], many transplant centers today may be reluctant to expose their recipient to an unknown presumed viral etiology of donor death.
However, primary EBV infection i. Therefore, recognition of this mismatch in a potential allograft recipient known to be EBV-negative may be important prognostic information. Currently, there is no effective means of preventing this complication.
The detection of antibody to treponemal antigen by the rapid plasma reagin test is not a contraindication to organ procurement [ 28 ], but it is a contraindication to tissue procurement.
Although syphilis can be transmitted by blood transfusion, we are unaware of previously described infection in a recipient of a transplant from a syphilitic donor.
Moreover, a standard course of penicillin therapy would provide sufficient antibiotic coverage to prevent syphilitic complications in an allograft recipient. The possible transmission of the protozoan Toxoplasma gondii is a concern especially for heart allograft recipients, because of the predilection of this parasite for muscle tissue. Organ procurement from seropositive donors is not contraindicated; however, the detection of seropositivity means that the recipient may be placed at high risk.
Fortunately, the use of trimethoprim-sulfamethoxazole as prophylaxis for Pneumocystis carinii infection prevents transmission of T. Google Scholar.

Cadaver policy October Page 4 of 43 1) Introduction There are approximately , deaths per year in the United Kingdom and about two-thirds occur in hospital and less than 1% are associated with a known or suspected infection. Final disposal of the body is usually days after death. Renal transplantation is the optimal treatment for many patients with end-stage renal disease, and for people with other end-stage organ diseases, transplantation may offer the only hope for survival. Unfortunately, the ability to deliver this medical miracle is limited by a severe shortage of human organs. As a result, many people with irreversible organ failure die while waiting for an organ Cited by: 8. See id. Those interests were: (1) the wishes of the deceased during his lifetime concerning the disposition of his body; (2) the desires of the surviving spouse or next of kin; (3) the interest of the state in determining by autopsy, the cause of death in cases involving crime or violence; (4) the need of autopsy to. Aug 06, · The need of Organ Donation in India Organ donation is fast developing into a major treatment protocol. However, it is yet to make a significant dent in India.
