20.500.12556/DiRROS-18158 Interventional radiological management of complications in renal transplantation Radiološka diagnostika in zdravljenje zapletov presajene ledvice Background. The most frequent radiologically evaluated and treated complications in renal transplantation are perirenal and renal fluid collection and abnormalities of the vasculature and collecting system. Renal and perirenal fluid collection is usually treated successfully with percutaneous drainage. Doppler US, MRA and digital subtraction angiography (DSA) are most important in the evaluation of vascular complications of renal transplantation and management of the endovaseular therapy. Conclusions. Stenosis, the most common vascular complication, occurs in 1% to 12% of transplanted renal arteries and represents a potentially curable cause of hypertension following transplantation and/or renal dysfunction. Treatment with percutaneous transluntinal renal angioplasty (PTRA) or PTRA with stent has been technically successful in 82 to 92% of the cases, and graft salvage rate has ranged from 80-100%. Complications such as arterial and vein thrombosis are uncommon. Intrarenal A/V fistulas and pseudoaneurysms are occasionally seen after biopsy, the treatment reguires superselective embolisation. Urologic complications are relatively uncommon; they consist predominantly of the urinary leaks and urethral obstruction. Interventional treatment consists of percutaneous nephrostomy, balloon dilation, insertion ofthe double J stents, metallic stent placement and external drainage of the extrarenal collections. The aim of the paper is to review the role of interventional radiology in the management of complications in renal transplantation. Izhodišča. Namen članka je podati pregled vloge intervencijske radiologije v diagnostiki in zdravljenju zapletov po presaditvi ledvic. Zapleti nastanejo nažilah, sečnih izvodilih ter v ledvici in njeni okolici v obliki patoloških tekočinskih formacij. Diagnostiko, načrtovanje in vodenje znotrajžilnega zdravljenja žilnih zapletov opravljamo z Dopplerskim ultrazvokom (UZ), magnetno resonanco (MR) in z digitalno subtrakcijsko angiografijo (DSA). Zaključki. Najpogostejši žilni zaplet presajene ledvice je zožitev ledvične arterije, ki se pojavi pri 1% -12% bolnikov. Nezdravljena zožitev je lahko razlog za arterijsko hipertenzijo in odpoved ledvice, čeprav je zaplet potencialno ozdravljiv. Zožitev zdravimo s perkutano transluminalno ledvično angioplastiko (PTRA) z uporabo žilne opornice ali brez nje, ki je za hipertenzijo uspešna v 82% - 92% primerov, ohranitev presajene ledvice pa je možna v 80% - 100%. Zapleti, kot sta arterijska in venska tromboza, so redki. Po biopsijah se občasno pojavijo znotraj ledvične arteriovenske fistule in psevdoanevrizme, ki jih zdravimo s superselektivno embolizacijo. Najpogostejšiurološki zapleti so zožitve, zapore in fistule sečevodov, ki jih zdravimo s perkutano nefrostomo, balonsko dilatacijo, vstavitvijo dvojne J kateterske opornice ali kovinske opornice. Tekočinske patološke kolekcije, kotso limfokele, abscesi, hematomi zdravimo s perkutano drenažo. true false true Association of Radiology and Oncology Ljubljana Angleški jezik Slovenski jezik by Authors Neznano 2024-02-13 10:08:30 2024-02-13 10:08:31 2024-02-14 03:49:57 0000-00-00 00:00:00 2004 0 0 BSDOCID112280; str. 309-321 št. 4 Letn. 38 2004 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2004-01-01 616-07 1318-2099 19026393 RAZ_Popovic_Peter_2004.pdf RAZ_Popovic_Peter_2004.pdf 1 C55EFA6EA04E1122D3BA2B30CC0597AD 52b02a03cc1a5b55a839528de8bec86b74a43f5c169965554898d0be8efccfbd 3d885d76-ca47-11ee-aa6e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24666 Onkološki inštitut Ljubljana 0 0 0
