“…In comparison, others have reported renal artery stenosis as the most common vascular complication (0.6%e10.5%). 10,13,20,22,33 Perirenal haematomas may not originate from vascular anastomosis but from bleeding in the renal hilar region caused by explantation. Therefore, only haematomas that were near the site of anastomosis were included as vascular complications and all other perirenal haematomas were excluded.…”

The surgeon's experience is an independent risk factor for vascular and haemorrhagic complications after KTx. Acceptable post-operative vascular and haemorrhagic complications are achieved after a minimum of 26 KTx. As a donor age of >60 years and recipient CVD are also independent risk factors for vascular and haemorrhagic complications, it is suggested that these patients should preferably be operated on by surgeons who have performed more than 26 KTx operations.

“…The risk factor of arterial thrombosis is the use of multiarterial kidney allograft. Some errors of surgical technique can lead to the thrombosis: unidentified intimal tear, technique defects of vascular stitch, artery's inflection (if the artery is longer than vein or if there is wrong localization of anastomosis formation) [1,3,[12][13][14][15][16]20]. The lack of arterial and vein blood flow in kidney allograft is determined in the process of Doppler study [15,18].…”

“…The lack of arterial and vein blood flow in kidney allograft is determined in the process of Doppler study [15,18]. Taking into account the lack of collateral vessels and low tolerance for warm ischemia such grafts are necessary to remove in the most cases [1,3,[12][13][14][15][16]20].…”

The adequacy of blood supply in the allograft is one of the main factors of kidney transplant vitality and function and the effectiveness of transplantation itself.The aim of the study was to investigate the effectiveness and variants of arterial reconstructions of kidney allograft. Material and Methods.The results of kidney transplantation were analyzed among 66 patients. During the period from 2012 to 2016, all of them were done kidney transplantation in the department of transplantology. There were 37 (56.1 %) men, 29 women (43.9 %), the average age at the time of surgery was 33.2 ± 12.0 years. According to the aim of the study all the patients were divided into two groups: the first group included 12 (18.2 %) recipients, who received an arterial reconstruction. The age of the patients was 30.8 ± 6.5 years, there were 6 (50 %) men, other -women. Another group involved 54 (81.8 %) patients without arterial reconstruction. The average age of recipients was 33.7 ± 12.9 years, there were 31 (57.4 %) men, 23 women (42.6 %). We analyzed duplex examination of kidney allograft on the 7.6 ± 1.9 day after kidney transplantation. Results.According to the analysis of duplex examination the features of blood disorder in kidney allografts were not determined. The differences between groups were non-significant (p > 0.05). There were not identified any stenosis, thrombosis or bleeding in any cases of arterial reconstructions of kidney allograft; function of kidney allograft has preserved for the period of 2.2 ± 1.4 years. Conclusions.Adequate arterial reconstruction of kidney allograft is effective and safe method of kidney preparation for transplantation. Одним із принципових факторів життєздатності та функції пересадженої нирки, а отже й ефективності трансплантації, є адекватність кровотоку в аллотрансплантаті.Мета роботи -вивчити ефективність і варіанти артеріальних реконструкцій ниркового аллотрансплантату.Матеріали та методи. Проаналізовані результати трансплантації нирки 66 хворим. З 2012 по 2016 р. їм виконана пересадка нирки у відділенні трансплантації. Чоловіків було 37 (56,1 %), жінок -29 (43,9 %), середній вік пацієнтів -33,2 ± 12,0 року. Згідно з метою роботи пацієнтів поділили на групи: першу становили 12 (18,2 %) реципієнтів, яким виконане хірургічне втручання на артеріях трансплантату. Середній вік пацієнтів -30,8 ± 6,5 року, чоловіків було 6 (50 %), інші -жінки; друга група -54 (81,8 %) пацієнти, в яких не було необхідності в артеріальних реконструкціях аллонирки. Середній вік реципієнтів -33,7 ± 12,9 року, чоловіків було 31 (57,4 %), жінок -23 (42,6 %). Аналізували дуплексне сканування ниркового аллотрансплантату в середньому на 7,6 ± 1,9 доби після пересадки нирки.Результати. Під час дуплексного ультразвукового сканування ознак порушення кровотоку в ниркових аллотрансплантатах не виявили. Відмінності між групами статистично невірогідні (p > 0,05). У жодному випадку не зареєстровано стенозів, тромбозів або кровотеч; за період спостереження 2,2 ± 1,4 року функція аллонирок збережена.Висновки. Адекватна артер...

“…[25][26][27] Early graft loss was mostly related to vascular thrombosis, which was considered to be related to technical problems. 28 Transplant physicians should have theoretical and practice expertise in Doppler ultrasonography for early detection of such complications. 29 It has been reported that prompt revascularization could allow for graft salvage.…”

Objectives: The aim of this study was to report the results of 30 years of experience at the first kidney transplant center in Tunisia. Materials and Methods: All kidney transplants performed at the center between June 1986 and June 2016 were included. The study period was divided into 3 decades. Recipient and donor data and follow-up information were obtained from a local database and patient medical records. Comparative analyses were performed using the t test for continuous variables and the χ 2 test for qualitative variables. Patient and graft survival rates were calculated according to the actuarial method, and comparison of survival curves was performed according to the logrank test. Results: The mean age of recipients was 32.7 ± 11.5 years (range, 6-65 y) with a gender ratio of 2.2. Duration of prekidney transplant dialysis varied from 2 months to 20 years (median, 27.5 mo); 1.7% of patients underwent transplant preemptively. Kidneys were recovered from deceased donors in 21.2% of cases and from living donors in 78.8%. The proportion of deceased donors dropped from 27.4% during the period 2006-2010 to 12.9% during the period 2011-2015 (P < 0.04). Patient survival rates at 1, 5, 10, 15, and 20 years were 96%, 89.3%, 79.5%, 71.1%, and 65.4%. Graft survival rates were 95%, 86.5%, 76.2%, 66.3%, and 57.2%. The annual graft loss was 2.9%, with a mortality rate of 2.4% and without significant differences between patients receiving deceaseddonor and living-donor organs. Conclusions: Kidney transplant activity remains suboptimal in our country. The reduction in deceaseddonor organs could be related to the political transformations facing our country with their resulting social and economic consequences. Efforts should be made to increase governmental resources and to improve both public awareness of organ donation and the motivation of transplant teams.
