Hemangiomas are frequent benign tumors of the liver. Symptoms (abdominal pain and fullness) are mostly seen in giant lesions. Rupture is the most severe complication, can occur spontaneously, with intraperitoneal bleeding, in 1-4% of hemangiomas and has been described in about 30 cases in the international literature with a high mortality (about 60%). This complication is the principal indication for surgery. Although spiral CAT scan and MR are actually the most efficacious imaging methods for study of liver hemangiomas, after Echography, emergency techniques that allows a simultaneous therapeutic approach--as is angiography--are preferable. Trans-arterial embolization (TAE) is in fact useful to stop bleeding and then to perform a safer surgery. A successful embolization can delay the surgical resection of the hemangioma for the time necessary to recover from the hemodynamic distress. Aside from the success of angiographic approach, surgery remains mandatory, effective in stopping the bleeding and in preventing re-bleeding or other complications of TAE such as abscess, fever, etc.. Intraoperative echography currently is the best method to identify vasculo- biliary anatomy and to perform a correct resection. The absence of risk factors for spontaneous rupture of liver hemangiomas, makes this event unpredictable. The best treatment for non-ruptured hemangiomas is still controversial but surgery is usually limited to symptomatic tumors larger than 10 cm.

Two cases of intraperitoneal hemorrhage, which is one of the major complications of percutaneous ethanol injection therapy for hepatocellular carcinoma, are reported. A 70-year-old man was hospitalized for treatment of a small recurrent hepatocellular carcinoma located on the surface of the left lobe of the liver. Acute hemoperitoneum developed after percutaneous ethanol injection therapy, but he was treated conservatively with blood transfusion, and recovered. The other patient was a 72-year-old man who was admitted for treatment of a solitary superficial hepatocellular carcinoma on the dome of the liver. Immediately after percutaneous ethanol injection, he suffered the sudden onset of severe abdominal pain with shock and massive hemoperitoneum. His bleeding was successfully controlled by emergency transcatheter arterial embolization. Our experience suggests that care must be taken when using percutaneous ethanol injection to treat patients with superficial hepatocellular carcinomas located on the surface of the liver. Moreover, transcatheter arterial embolization should be considered the treatment of choice for the management of uncontrollable intraperitoneal hemorrhage after percutaneous ethanol injection therapy.

We describe a rare case of spontaneous rupture of a hepatic metastasis from renal cell carcinoma that was treated successfully by hepatic arterial embolization. A 65-year-old woman, who had been undergoing immunotherapy for inoperably disseminated renal carcinoma and lung metastases, presented with severe abdominal pain in a state of hypovolemic shock. Computed tomography revealed a highly attenuated mass lesion in the right lobe of the liver and massive intraperitoneal hemorrhage. Subsequent hepatic angiography showed extravasation from the feeding right hepatic artery. Transcatheter embolization of the right hepatic artery was subsequently performed, and the patient made an uneventful recovery. Although hepatic rupture due to metastatic cancer is extremely rare, transcatheter arterial embolization (TAE) is an appropriate and useful treatment for massive hemorrhage caused by spontaneous rupture of liver metastasis.

Hemoperitoneum is a well-known form of hepatocellular carcinoma presentation and represents a frequent complication in countries with a high incidence of hepatocellular carcinoma, but it is rarely seen in Western countries. Our aim was to report the results and describe the arteriographic and CT-scan characteristics in a series of seven consecutive patients. They were admitted to our hospital because of hemoperitoneum due to ruptured tumor as a first manifestation of hepatocellular carcinoma, and the rupture was effectively controlled by transcatheter arterial embolization. From April 1989 to April 1998, 440 consecutive patients were admitted to our liver unit with the diagnosis of hepatocellular carcinoma and liver cirrhosis. Fourteen patients (3%) presented with acute hemoperitoneum due to tumor rupture as a first manifestation of hepatocellular carcinoma. We here report our experience in the group of patients treated by transcatheter arterial embolization. Mean age was 67.1+/-5 years (range, 61-73). All patients presented with sudden abdominal pain, abdominal distension, and four patients had symptoms of acute anemia. In all cases the ruptured tumor was subcapsular. The procedure was effective in the control of bleeding in all cases, without significant impairment in liver function or treatment-related deaths. In six of the seven patients, a self-limited postembolization syndrome was observed. Mean survival time was 273+/-488.7 days (range: 15-1290). Three patients survived more than six months but at the time of evaluation, only one patient was alive. In conclusion, the present results confirm that transcatheter arterial embolization is an effective and well-tolerated treatment in the management of hemoperitoneum due to ruptured hepatocellular carcinoma in patients with liver cirrhosis.

We report the case of a 51-year-old man with hepatic amebic abscess complicated by hepatic artery aneurysm. The patient first presented with peritonitis caused by perforating appendicitis. Surgical treatment resolved peritonitis but Entamoeba histolytica was detected in the colonic mucosa. Subsequently, liver abscess developed and the size of the abscess increased gradually after surgery in spite of continued treatment with metronidazole. Brown pus was drained from the abscess but 13 days after the drainage process the patient complained of right upper abdominal pain and the drained fluid became blood-colored and stool became tarry in color. Enhanced computed tomography showed a hepatic artery aneurysm that had ruptured into the liver abscess and duodenoscopy revealed bleeding from the ampulla of Vater. Transcatheter arterial embolization with several steel coils was successfully performed which resulted in cessation of bleeding from the ampulla of Vater. The patient was discharged without any complications five weeks after rupture of the aneurysm. Our case demonstrates rupture of the hepatic artery aneurysm as a rare complication of amebic liver abscess and the effectiveness of interventional embolotherapy in this condition.

When surgical treatment is being considered for focal nodular hyperplasia, the risk of liver surgery must be carefully balanced against the benefit of resection, especially in the case of a large or centrally located lesion. However, when resection is contraindicated or even impossible, transcatheter arterial embolization should be considered as a safe and less invasive alternative treatment. We describe two cases of young women who presented with abdominal pain and a hypervascular enhancing mass with the radiologic features of focal nodular hyperplasia. Arterial embolization was the therapy selected due to the risk of surgery. In both cases the procedure was successful, and the lesion showed shrinkage during follow-up.

Acute pancreatitis can complicate non-selective transcatheter arterial embolization of hepatocellular carcinoma with an incidence ranging from 1,7% (acute clinical pancreatitis) to 40% (biological pancreatitis). This complication is thought to be related to embolization of extrahepatic arterial collaterals. We report herein a case of acute clinical pancreatitis developing within 24 hours after a second course of selective transcatheter arterial chemo-embolization into the proper hepatic artery. Neither anatomical arterial variation nor particular risk factor for acute pancreatitis could be identified. This complication is unusual after selective arterial embolization. Because it may clinically mimick a postembolization syndrome, dosage of serum pancreatic enzymes should be performed systematically in case of abdominal pain following chemoembolization.

We report two cases of a nonparasitic solitary huge liver cyst. The first case, that of a 42-year-old woman, was admitted with a chief complaint of upper abdominal pain. Computed tomography (CT) scans revealed a huge cyst, 10 cm in diameter, in segments 4 and 5 of the liver, and spontaneous rupture of the cyst with intracystic hemorrhage. Her general condition was improved by transcatheter arterial embolization (TAE). Percutaneous cystic needle aspiration cytological examination revealed no malignant cells, so she was discharged. After 3 weeks, however, the cyst had increased in size, and simple cystectomy was performed. Histological examination proved the cyst to be benign. The patient in the second case, a 70-year-old man, was admitted with epigastric discomfort and obstructive jaundice. CT scans revealed a huge liver cyst, 18 x 15 cm, in the right lobe of the liver, with dilation of the bile duct in the lateral segment. Magnetic resonance cholangiopancreatography showed compression of the left hepatic duct by the cyst and dilation of the bile duct in the lateral segment. Endoscopic retrograde cholangiopancreatography disclosed no communication between the bile duct and the cyst. Percutaneous transhepatic cyst drainage was performed, and minocycline hydrochloride was infused. The cyst was reduced in size, and the reduction has been maintained for 20 months since treatment.

Tuberous sclerosis complex (TSC) is an autosomal-dominant neurocutaneous disorder involving the skin, brain, kidney, heart and other organs. Renal manifestations are mainly angiomyolipomas, renal cysts and cancer. We report three female patients, mean aged of 31 years (range: 22-37), with a family history of TSC in one case. Cutaneous and nervous symptoms were found in all patients. Clinical complaints were mainly abdominal pain (3 cases), hematuria (2 cases), right flank palpable mass (1 case). Angiomyolipomas (AML) were diagnosed by ultrasonography in all patients, associated to renal cysts in one case. A patient underwent total right nephrectomy without any event during the follow-up. In a second patient, a selective arterial embolization of AML was indicated. Total left nephrectomy was performed due to the persistence of hematuria and the increased flank mass. Pathological examination of the kidney revealed a clear cell carcinoma. The third patient with small AML, associated with renal cysts, required careful monitoring. Renal manifestations in TSC are frequent and serious, they are the second leading cause of death after nervous lesions. Clinical and morphological aspects are variable and different therapeutic indications must be discussed.

Hemosuccus pancreaticus is a rare complication of chronic pancreatitis. We report two cases of hemosuccus pancreaticus in which hemostasis was achieved by transcatheter arterial embolization (TAE). The first patient was a 47-year-old man with alcoholic chronic pancreatitis. He presented with upper abdominal pain and hematemesis. Upper GI endoscopy failed to detect the source of bleeding, but computed tomography (CT) showed a hypervascular area about 3 cm in diameter in a pseudocyst at the pancreatic tail. Angiography revealed a pseudoaneurysm in the caudal pancreatic artery. Hematemesis was considered to be due to rupture of the pseudoaneurysm. TAE of the splenic artery was performed selectively, and this successfully stopped the bleeding. The second patient was a 52-year-old man with alcoholic chronic pancreatitis. He presented with hematemesis. Upper GI endoscopy detected bleeding from the papilla of Vater. CT showed hemorrhage in a pseudocyst at the pancreatic body. Angiography revealed angiogenesis around the pseudocyst. Hematemesis was considered to result from rupture of the pseudoaneurysm. TAE of the dorsal pancreatic artery and posterior superior pancreaticoduodenal artery was performed and hemostasis was achieved. We conclude that TAE is a minimally invasive and highly effective treatment for hemosuccus pancreaticus.
