But de l'etude<space>: Cette etude retrospective avait pour but de rapporter une serie de neuf anevrysmes des arteres hepatiques reunissant des anevrysmes vrais (n<space>=<space>4), des pseudo-anevrysmes (n<space>=<space>3) et des faux anevrysmes (n<space>=<space>2) observes entre 1987 et 1999.Patients : Il s'agissait de sept hommes et deux femmes (age moyen<space>: 58 ans). Dans trois cas, l'anevrysme etait asymptomatique, decouvert fortuitement par echo-Doppler<space>; dans quatre cas, la rupture a ete revelatrice, entrainant une hemorragie grave<space>; dans deux cas, l'anevrysme a ete revele par une cholestase. L'anevrysme siegeait sur l'artere hepatique droite (n<space>=<space>3), commune et propre (n<space>=<space>3), propre (n<space>=<space>2), commune (n<space>=<space>1). L'anevrysme etait associe a un cancer de la tete du pancreas (n<space>=<space>1), un hepatocarcinome (n<space>=<space>1) et a des metastases hepatiques (n<space>=<space>1).Methode et resultats<space>: Huit patients ont ete operes dont un a trois reprises. Le foie a ete revascularise six fois : par suture directe (n<space>=<space>1), par greffon de Goretex(R) (n<space>=<space>1), par allogreffe (n<space>=<space>2), par greffon veineux autologue (n<space>=<space>1), avec un echec ayant conduit a une retransplantation hepatique. Sur trois tentatives d'embolisation, il y a eu un seul succes. Un patient qui ne pouvait pas etre opere est decede d'hemobilie apres echec de l'embolisation. Au cours du suivi, il y a eu une thrombose de l'artere hepatique commune apres exclusion. Deux patients sont decedes secondairement, l'un par rupture d'un faux anevrysme anastomotique apres pontage par allogreffe, l'autre au stade terminal du cancer metastase. Les six autres patients etaient vivants au moment de l'etude.Conclusion<space>: Les anevrysmes des arteres hepatiques realisent des tableaux cliniques varies. Les indications therapeutiques sont difficiles a poser. Le traitement est surtout chirurgical et l'embolisation reservee a des circonstances particulieres. La revascularisation du foie est necessaire dans les anevrysmes interessant l'artere hepatique propre.
Aim of the study: The aim of this retrospective study was to report a series of nine aneurysms of the hepatic arteries, including real aneurysms (n<space>=<space>4), pseudoaneurysms (n<space>=<space>3) and false aneurysms (n<space>=<space>2) observed from 1987 to 1999.Patients: There were 7 men and 2 women (mean age: 58 years). In 3 cases, the aneurysm was asymptomatic and detected by sonography; in 4 cases it was revealed by rupture with a severe hemorrhage and in 2 cases by cholestasis. The aneurysm was located on right (n<space>=<space>3), proper and common (n<space>=<space>3), proper (n<space>=<space>2), and common (n<space>=<space>1) hepatic arteries. The aneurysm was associated with hepatocellular carcinoma (n<space>=<space>1), carcinoma of the head of the pancreas (n<space>=<space>1) and liver metastases (n<space>=<space>1).Methods and results: Eight patients were operated and one of them was operated three times. Hepatic arterial blood supply was restored in 6 patients with simple suture (n<space>=<space>1), Goretex(R) graft (n<space>=<space>2), allograft (n<space>=<space>2) and autologous vein (n<space>=<space>1), with one failure which required liver retransplantation. Only one of the three attempts of embolization was successful. One patient with surgical contraindications died from hemobilia after embolization failure. During follow-up, there was one thrombosis of the common hepatic artery which had been excluded and two late deaths: one from rupture of a false aneurysm after bypass with an allograft and one by terminal progression of the cancer. The other 6 patients were alive at the time of this study.Conclusion: Clinical characteristics and therapeutic indications of hepatic arterial aneurysm are variable. Management is usually surgical, while embolization is reserved for special circumstances. Restoration of the hepatic arterial blood supply is necessary in aneurysms located on the proper hepatic artery.
