Treatment of extrahepatic portal hypertension in children by mesenteric-to-left portal vein bypass: a new physiological procedure.

OBJECTIVE: To achieve hepatic portal revascularisation and decompression of extrahepatic portal hypertension in children with cavernoma and obstruction caused by idiopathic portal vein thrombosis. DESIGN: Selected cases. SETTING: Teaching hospitals. Belgium and Italy. SUBJECTS: 11 children who weighed between 5.9 and 54 kg (2 emergencies) with symptomatic extrahepatic portal hypertension. INTERVENTION: Interposition of venous autograft between the superior mesenteric vein and the distal (umbilical) portion of the left portal vein. MAIN OUTCOME MEASURES: Improvements in symptoms and endoscopic appearance after operation. RESULTS: 2 bypasses had to be redone because they stenosed; all 11 were patent at the time of writing (median follow-up 6 months, range 1-32 months). CONCLUSION: The bypass effectively relieved symptoms of extrahepatic portal hypertension by restoring normal hepatic portal blood flow.

Clinical use of Levovist, an ultrasound contrast agent, in the imaging of liver transplantation: assessment of the pre- and post-transplant patient.

Colour Doppler US is well established for imaging of hepatic vessels in the assessment of pre- and post-liver transplant patients. Unfortunately, a full colour Doppler US examination of the portal or hepatic venous and hepatic arterial systems is frequently precluded by technical factors. Ultrasound contrast agents are useful in enhancing vascular Doppler signal and play an important role in liver transplantation assessment. A series of patients with vascular problems illustrates the role of US contrast in the pre-transplant candidate, where portal vein patency and direction of flow is assessed, presence of portal vein thrombus is confirmed and cavernous transformation demonstrated. Occlusion of hepatic veins in Budd-Chiari syndrome is confidently confirmed. Following liver transplantation, US contrast allows a comprehensive assessment of hepatic artery thrombosis, hepatic artery stenosis and pseudoaneurysm formation. The need for further imaging is reduced or confidently deferred in many instances. Ultrasound contrast agents play an important role in the liver transplant candidate.

Primary antiphospholipid syndrome presenting with abdominal angina and splenic infarction.

The antiphospholipid syndrome is an autoimmune hypercoagulability syndrome in which a wide variety of thromboembolic diseases may occur. Gastrointestinal manifestations associated with vascular occlusion include Budd-Chiari syndrome, hepatic and splenic infarction, pancreatitis, omental and intestinal infarction, and esophageal variceal bleeding due to portal vein thrombosis, but chronic mesenteric ischemia associated with mesenteric arterial thrombosis is very rare in this syndrome. We experienced a female patient with primary antiphospholipid syndrome with abdominal angina and splenic infarction associated with celiac trunk and mesenteric arterial thromboses. This is the first report describing chronic mesenteric ischemia and splenic infarction in a patient with primary antiphospholipid syndrome.

Risks and side effects of islet transplantation.

Islet transplantation can deliver stable glycemic control, relief from recurrent severe hypoglycemia, and insulin independence. Accessing the portal vein via the percutaneous hepatic approach carries the risk of bleeding, and the infusion of islets a risk of portal vein thrombosis. In the long term, common minor problems with immunosuppression are mouth ulcers, diarrhea, and acne. Longer-term risks include malignancy and serious infection, both rare to date in clinical islet transplantation. Sensitization to donor antigens may also occur. The long-term diabetes complications may stabilize, but of this aspect little is known to date. In the short term, there may be some elevation of serum cholesterol and blood pressure, in some patients there has been a decline in renal function, and in a few, acute retinal bleeds. For most, improvement in glucose control with resolution of glycemic lability and hypoglycemia has been a net benefit.

Case report: Hepatic involvement in antiphospholipid syndrome.

Three cases of hepatic involvement in antiphospholipid syndrome are described. One patient had catastrophic antiphospholipid syndrome with haemorrhages and necrosis in the liver parenchyma. The second patient had blood clots in the small hepatic vessels. The third patient had autoimmune hepatitis type I associated with antiphospholipid syndrome. Other possible hepatic manifestations of antiphospholipid syndrome are also discussed.

Pregnancy in patients with chronic liver disease.

The pregnant patient with established chronic liver disease presents a unique situation in medicine. Although neither the pregnancy nor the liver disease is likely to specifically worsen the other, the combination can result in fatal complications for mother and infant. Fertility is decreased in patients with advanced liver disease and may provide a degree of protection for many patients who would be at increased risk should they become pregnant; however, pregnancy may occur even with advanced liver disease, and it is necessary to anticipate and plan for possible complications of the specific hepatic disease encountered. Counseling prior to pregnancy is the best policy, with consideration to transplantation prior to childbearing or to sterilization if it is more appropriate. Most problems associated with advanced liver disease are managed as in the nonpregnant patient; however, variceal bleeding may be a particularly difficult problem, and management here may necessitate portacaval shunt surgery.

Surgery of tumors of the subdiaphragmatic inferior vena cava. Report of two cases and review of the literature.

Two cases of obstruction of the hepatic inferior vena cava (IVC) are presented. In Case 1, the obstruction was due to a calcified thrombus which presumably developed after lower limb trauma 19 months previously. Complete surgical correction was achieved with the aid of deep hypothermia and circulatory arrest. In Case 2, a right atrial tumor was mimicked by a propagating malignant hepatoma. Palliative removal of the tumor cleared the IVC passage. The etiology of tumors of the IVC and their surgical management are discussed.

[Congenital and acquired anomalies of the inferior vena cava. Differential diagnosis using digital subtraction angiography and computed tomography].

Segmental aplasias of the inferior vena cava, thrombosis of the vena cava, tumour infiltration (e.g. renal neoplasms via the renal vein) and external compression (e.g. large hepatic metastases) may produce similar radiomorphologic changes in chest x-ray DSA and CT. These radiomorphological changes are described by case reports. DSA clearly demonstrates the course of the vessels and the collaterals involved. CT may elucidate the paracaval vascular changes. It is only a synopsis of cavography (DSA) and CT with reference to embryogenesis that will lead to a reliable diagnosis and enable a definite decision on therapy and prognosis.

Vascular and biliary complications after liver transplantation: interventional treatment.

OBJECTIVE: To evaluate the value of angiography and cholangiography on the diagnosis and interventional treatment of vascular and biliary complications after liver transplantation. METHODS: Sixteen of 46 patients (15 men and 1 woman, 17 - 60 years old) after orthotopic liver transplantation received angiography due to abnormal ultrasonography or edema of lower limbs, or cholangiography due to progressing jaundice. Percutaneous transluminal angioplasty or drainage was performed in some patients. RESULTS: Fifteen patients experienced vascular complications and 4 patients had biliary complications. Three of them appeared to have both vascular and biliary complications. Hepatic artery complications were the most common complications (9/16), including hepatic artery thrombosis or stenosis (6/9), bleeding (2/9) and hepatic artery-dissecting aneurysm (1/9). One patient with hepatic artery thrombosis received transcatheter thrombolysis and two patients with bleeding received coil embolization. Inferior vena cava and portal vein stenosis were observed in 6 and 2 patients, respectively. After balloon angioplasty or stent placement, clinical symptoms were alleviated. Biliary complications, including biliary stricture and anastomotic bile leak, occurred in 4 patients. Jaundice decreased after percutaneous transhepatic cholangiography and drainage. CONCLUSIONS: Besides diagnosis, interventional methods include mini-invasive treatment for patients with vascular and biliary complications after liver transplantation. Balloon angiography and stent placement for venous stenosis are useful procedure for the treatment of these problems.

Transcatheter arterial chemoembolization with anticancer drug in iodized oil for primary hepatic carcinoma.

Transcatheter arterial chemoembolization using a suspension of anticancer drug in iodized oil combined with Gelfoam embolization was performed in 85 patients with advanced primary hepatic carcinoma. Long-term retention of iodized oil in the tumor was observed in 90% of the cases, and changes in tumor size were observable by abdominal X-ray film on follow-up studies. There was a decrease of tumor size in all cases and the overall 1-year survival rate was 43%. In tumors whose diameter was less than 20 cm and in patients without portal vein thrombosis the survival rate was nearly 60%. Combined treatment with anticancer drug in iodized oil and Gelfoam embolization of the proper hepatic artery was superior to use of the suspension alone. There was also better detection of small cancer nodules by the suspension as compared to conventional angiography.
