Active intrahepatic gadolinium extravasation following TIPS

Intrahepatic hematoma secondary to transjugular intrahepatic portosystemic stent-shunt procedure: Case report and literature review

RATIONALE

Transjugular intrahepatic portosystemic stent-shunt (TIPSS) is a minimally invasive procedure used for the treatment of portal hypertension. Intrahepatic hematoma is the rare complication caused by hepatic arterial injuries from TIPSS procedure.

PATIENT CONCERNS

This case report illustrated a 77-year-old man with hepatitis B virus-induced cirrhosis who underwent TIPSS.

DIAGNOSES

The patient suffered from intrahepatic hematoma and hepatic pseudoaneurysm because of the hepatic artery injury after TIPSS.

INTERVENTIONS

The hepatic artery laceration began at the level of the branch of the left hepatic artery was embolized.

OUTCOMES

The acute intrahepatic hematoma and hepatic pseudoaneurysm of the patient were cured.

CONCLUSION

In this report, we describe a cirrhosis patient with a large intrahepatic hematoma secondary to TIPSS, and a literature review is also presented. The intrahepatic hematoma and hepatic pseudoaneurysm should be paid more attention after TIPSS while early-stage prevention should be carried out.

Active extravasation of gadolinium-based contrast agent into the subdural space following lumbar puncture

A 38year-old male presented with cauda equina syndrome following multiple lumbar puncture attempts. Lumbar spine magnetic resonance imaging (MRI) showed a subdural hematoma and an area of apparent contrast enhancement in the spinal canal on sagittal post-contrast images. Axial post-contrast images obtained seven minutes later demonstrated an increase in size and change in shape of the region of apparent contrast enhancement, indicating active extravasation of the contrast agent. This is the first reported case of active extravasation of gadolinium-based contrast agent in the spine.

Transjugular intrahepatic portosystemic shunt complications: prevention and management

Transjugular intrahepatic portosystemic shunt (TIPS) insertion has been well established as an effective treatment in the management of sequelae of portal hypertension. There are a wide variety of complications that can be encountered, such as hemorrhage, encephalopathy, TIPS dysfunction, and liver failure. This review article summarizes various approaches to preventing and managing these complications.

Transjugular intrahepatic portosystemic shunt in the treatment of Budd-Chiari syndrome: a critical review of literatures

An increasing number of patients with Budd-Chiari syndrome (BCS) have undergone transjugular intrahepatic portosystemic shunt (TIPS). However, the critical role of TIPS in the treatment of BCS has not been systematically reviewed. The authors identified all relevant literatures via the PubMed, EMBASE and Cochrane library databases. Overall, 160 papers from 29 countries reported the application of TIPS for BCS. The number of publications was increased over time, but the level of evidence in this field was low. Common indications for TIPS in BCS patients included refractory ascites, recurrent variceal bleeding, diffuse hepatic vein thrombosis and progressive liver failure. Successful TIPS insertion could improve the hemodynamic and clinical parameters. TIPS procedure-related complications were not infrequent (range: 0-56%), but procedure-related death was rare. Shunt dysfunction rate appeared to be higher (range: 18-100%). Compared with bare stents, covered stents could significantly decrease the rate of shunt dysfunction. Hepatic encephalopathy rate after TIPS was relatively low (range: 0-25%). Short- and long-term prognosis of BCS-TIPS patients was excellent with 1-year cumulative survival rate of 80-100% and 5-year cumulative survival rate of 74-78%. In conclusions, existing literatures supported the feasibility, safety and efficacy of TIPS in the treatment of BCS. Prospective cohort studies or randomized controlled trials were difficult due to the rarity of BCS, but might be very necessary to precisely identify the timing of transition from medical therapy and/or percutaneous recanalization to TIPS insertion and the real candidates in whom early TIPS should be promptly employed with no need of any prior therapy.

Delayed liver laceration following transjugular intrahepatic portosystemic shunt for portal hypertension

The transjugular intrahepatic portosystemic shunt (TIPS) is an acceptable procedure that has proven benefits in the treatment of patients who have complications from portal hypertension due to liver cirrhosis. Delayed liver laceration is a rare complication of the TIPS procedure. We describe a patient with portal hypertension due to liver cirrhosis, who suddenly presented with abdominal hemorrhage and liver laceration 8 d after TIPS. Few reports have described complications after TIPS placement. To the best of our knowledge, this is the first report describing delayed liver laceration. This potential and serious complication appears to be specific and fatal for TIPS in portal hypertension. We advocate careful attention to the technique to avoid this complication, and timely treatment is extremely important.

Active gastrointestinal hemorrhage identification by blood pool contrast-enhanced magnetic resonance angiography

Localization of the source of gastrointestinal hemorrhage can be challenging. Currently, this is often accomplished with tagged red blood cell scintigraphy, with attendant ionizing radiation and relatively poor spatial resolution. We describe an analogous method of detecting acute gastrointestinal hemorrhage by enhanced MRI with blood pool contrast agent. Briefly, following precontrast fat-suppressed volumetric T1-weighted image acquisition, single-dose gadofosveset trisodium, a blood pool agent, is administered. Then serial post-T1-weighted images are obtained. This technique is a novel method for evaluating gastrointestinal hemorrhage.

Paroxysmal nocturnal hemoglobinuria in Budd-Chiari syndrome: findings from a cohort study

BACKGROUND/AIMS

A well recognized cause of Budd-Chiari syndrome (BCS) is paroxysmal nocturnal hemoglobinuria (PNH). PNH is an acquired disorder of hematopoietic stem cells, characterized by intravascular hemolysis and venous thrombosis. Testing for this hematological disorder should be considered in all BCS patients.

METHODS

Using data from the EN-Vie study, a multi-center study of 163 patients with BCS, we investigated the relationship between BCS and PNH in 15 patients with combined disease and compared the results to 62 BCS patients in whom PNH was excluded.

RESULTS

Median follow-up for the study group (n=77) was 20 months (range 0-44 months). BCS patients with PNH presented with a significantly higher percentage of additional splanchnic vein thrombosis (SVT) as compared to BCS patients without PNH (47% vs. 10%, p=0.002). During follow-up, type and frequency of interventions for BCS was similar between both groups. Six patients with BCS and PNH were successfully treated with a transjugular intrahepatic portosystemic shunt (TIPS). Of 15 patients with PNH, six underwent allogenic stem cell transplantation after diagnosis of BCS. PNH was successfully cured in five cases. There was no significant difference in survival between BCS patients with and without PNH.

CONCLUSIONS

This study shows that despite a higher frequency of additional SVT, short-term prognosis of BCS patients with PNH does not differ from BCS patients without PNH. Treatment with TIPS can be safely performed in patients with PNH. Stem cell transplantation appears to be a feasible treatment option for PNH in BCS patients.

Interventional radiology in the management of Budd Chiari syndrome

Budd Chiari syndrome is an uncommon condition in the Western world but interventional radiology can contribute significantly to the management of the majority of patients. This review examines the role and technique of interventions including hepatic vein dilatation and stent insertion as well as thrombolysis and TIPS. Liver transplantation and surgical shunt surgery are discussed in relation to radiological interventions. With appropriate selection and technique, surgery is only required in a minority of patients.

Late intrahepatic hematoma complicating transjugular intrahepatic portosystemic shunt for Budd-Chiari syndrome

Late intrahepatic hematoma is a rare complication of the transjugular intrahepatic portosystemic shunt (TIPS) procedure. We describe a patient with Budd-Chiari syndrome (BCS), who presented with a large inrahepatic hematoma 13 days after TIPS. Review of the literature reveals only two previous cases, both occurring in patients with BCS and presenting after a similar time interval. This potentially serious complication appears to be specific for TIPS in BCS.

TIPS for acute and chronic Budd-Chiari syndrome: a single-centre experience

BACKGROUND/AIMS

Transjugular intrahepatic portosystemic shunt (TIPS) is a technically challenging but feasible treatment for Budd-Chiari syndrome (BCS). However, information about the outcome, particularly in patients with liver failure, is scarce. We report our experience of TIPS for BCS.

METHODS

Fifteen patients with BCS underwent TIPS. Eight had hepatic failure and seven underwent TIPS for BCS uncontrolled by medical treatment.

RESULTS

Fourteen out of 15 had successful TIPS placement. Out of the eight hepatic failure patients, four died soon after TIPS: one liver rupture, one portal vein rupture, one liver failure and one pulmonary oedema. Another patient had a significant intrahepatic haematoma, which resolved with conservative management. TIPS was successfully placed in all of the seven patients with chronic BCS, in whom there was an average follow-up of 20 months. Ascites resolved and liver function improved in all. One patient died after 18 months from the original hepatic metastatic disease. Four patients have had evidence of TIPS dysfunction requiring three balloon dilatations and one restenting. No patient has required liver transplantation.

CONCLUSIONS

TIPS should be the first line treatment for BCS uncontrolled by medical therapy. However, mortality in BCS with hepatic failure is high and liver transplantation could be a better option.
