Seventeen consecutive patients underwent partial hepatectomies, with total pedicular clamping of the afferent hepatic flow. Three of the resections were performed under emergency circumstances, due to hemiperitoneum as a result of ruptured hemangiomae, and the other excisions were carried out electively. The time during which the afferent hepatic blood flow was interrupted varied from a minimum of 20 minutes to maximum of 104 minutes, with an average of 48 minutes. One patient who had been submitted to emergency surgery died in the immediate postoperative period- a death rate of 5.8% - and general morbidity was 23.5% (4 cases). In the group show, no documentation demonstrated that complete interruption of afferent hepatic blood flow was responsable for postoperative morbidity or mortality. We believe that this technique is particularly useful in making the resection process easier.
Dezessete pacientes consecutivos foram submetidos a hepatectomias parciais com clampeamento pedicular total do fluxo aferente hepático. Três das ressecções foram efetuadas em caráter de emergência por hemoperitônio dependente de ruptura de hemangiomas, sendo as demais exéreses realizadas eletivamente. O tempo de impedimento do fluxo sangüíneo aferente hepát ico foi de um mínimo de 20 minutos até um máximo de 104 minutos com uma média de 48 minutos. Um paciente operado em caráter de emergência faleceu no pós-operatório imediato - mortalidade de 5,8% - e a morbidade geral foi de 23,5% (4 casos). No grupo apresentado não houve documentação que pudesse comprometer o impedimento total do fluxo sangüíneo aferente hepático como responsável por morbimortalidade pós-operatória. É nosso pensamento que a técnica facilita de modo conspícuo o processo de ressecção.
