ABSTRACT

PURPOSE: This work aimed at introducing the transjugular liver biopsy technique oriented by radiologic methods in our hospitals. This technique is indicated for obtaining histopathologic diagnosis in patients clinically and laboratory suspected of having chronic liver disease with contraindications to percutaneous liver biopsy. METHODS: Liver biopsy was obtained with a modified Ross needle through the right jugular vein and right hepatic vein under fluoroscopic control. RESULTS: Transjugular liver biopsy was attempted for 39 patients, liver tissue obtained en 32 and histopathologic diagnosis in 25 (64.1%). In 11 patients (28.2%) there was agreement between the diagnoses established before and after biopsy, however, in 14 patients (35.9%), there was disagreement. The yield of diagnosis was low when patients were suspected for cirrhosis. The procedure was well tolerated by the majority of patients. Nonetheless, 1 presented intra-abdominal bleeding and required immediate surgery to control retroperitoneal hemorrhage. CONCLUSIONS: Transjugular liver biopsy is useful for the histopathologic diagnosis of patients with chronic liver diseases whenever the percutaneous route is contraindicated. In this series we obtained histopathologic diagnosis for 64.1% of the subjects studied. Patients suspected of having cirrhosis had a low yield of histopathologic diagnosis (50%) when compared to subjects without clinical evidence for cirrhosis (78.9%). The technique is rather complex, and can cause serious complications. This, it should be performed in reference centers in radiology and hepatology.

ABSTRACT

OBJETIVOS: O trabalho visou introduzir em nosso meio a técnica de biópsia hepática transjugular orientada por métodos radiológicos para a obtenção do diagnóstico histológico em pacientes clínica e laboratorialmente diagnosticados com hepatopatia crônica e com pelo menos uma das contra-indicações à biópsia hepática percutânea: coagulopatia, ascite maciça e anemia crônica acentuada com insuficiência renal crônica ou obesidade mórbida. MÉTODOS: Biópsia hepática aspirativa foi obtida com agulha de Ross modificada, através da punção da veia jugular interna com cateterização da veia hepática direita sob controle fluoroscópico. RESULTADOS: Trinta e nove pacientes foram estudados, obtendo-se tecido hepático em 32 (82 por cento ) sendo satisfatório para diagnóstico histológico em 25 (64,1 por cento ), com concordância entre o diagnóstico pré e pós-biópsia em 11 (28,2 por cento ) e discordância em 14 pacientes (35,9 por cento ). O procedimento foi bem tolerado pela maioria dos pacientes; contudo um paciente apresentou sangramento retroperitoneal, necessitando cirurgia imediata para controle da hemorragia. CONCLUSÕES: A biópsia hepática transjugular é um método diagnóstico útil para o estudo histopatológico na suspeita de hepatopatia crônica com contra-indicações a biópsia hepática percutânea. Em nossa série foi obtido diagnóstico histopatológico em 64,1 por cento dos indivíduos estudados. Pacientes com suspeita clínica de cirrose tiveram baixo diagnóstico histopatológico (50 por cento ) quando comparados com indivíduos sem essa suspeita (78,9 por cento ). O método é relativamente complexo, podendo apresentar complicações graves, e deve ser realizado em centros de excelência em radiologia e hepatologia.

ABSTRACT

Caliceal-cutaneous fistula is an uncommon complication of renal transplantation that frequently leads to graft resection. We report our experience with the successful conservative management of a case of caliceal-cutaneous fistula secondary to acute allograft rejection in a renal transplant recipient.
