Transjugular intrahepatic portosystemic shunt (TIPS) in Spain. Clinical-epidemiological considerations in relation to a multicenter registry.

Objective: this study aimed to determine the epidemiological, technical and clinical data of transjugular intrahepatic portosystemic shunt (TIPS) performed by Interventional Radiology departments in Spain. Furthermore, the total number of TIPS carried out in Spain was determined and compared with other countries.

Material And Methods: a retrospective study was performed with the approval of the Ethical Committee of the Spanish Society of Interventional Radiology (SERVEI).

Safety and efficacy of expanded polytetrafluoroethylene-covered transjugular intrahepatic portosystemic shunts in children with acute or recurring upper gastrointestinal bleeding.

Background: The transjugular intrahepatic portosystemic shunt (TIPS) is effective for treating complications of portal hypertension in cirrhotic adults but the experience in children is limited.

Objective: To retrospectively review the safety and efficacy of expanded polytetrafluoroethylene (ePTFE)-covered TIPS in children with acute or recurrent gastrointestinal bleeding.

Materials And Methods: We reviewed the medical records of children who received implants of 10-mm-diameter PTFE-covered endoprostheses for acute or recurring upper gastrointestinal bleeding caused by medically or endoscopically uncontrollable varices.

Percutaneous radiofrequency ablation of renal tumors in solitary kidney patients.

Objectives: In solitary kidney patients with renal cell carcinoma (RCC), radiofrequency ablation (RFA) could be effective in achieving complete tumor necrosis without increasing the risk of complications or renal failure. To analyze the outcomes of a group of solitary kidney patients treated for RCC by RFA considering tumor size and location, renal function involvement and complications.

Methods: A transversal retrospective study was performed, in which we selected 11 solitary kidney patients with 19 tumors in total treated by RFA for one or more renal tumors.

Late hepatic artery pseudoaneurysm: a rare complication after resection of hilar cholangiocarcinoma.

We report an unusual pathological entity of a pseudoaneurysm of the right hepatic artery, which developed two years after the resection of a type II hilar cholangiocarcinoma and secondary to an excessive skeletonization for regional lymphadenectomy and neoadjuvant external-beam radiotherapy. After a sudden and massive hematemesis, a multidetector computed tomographic angiography (MDCTA) showed a hepatic artery pseudoaneurysm. Angiography with embolization of the pseudoaneurysm was attempted using microcoils with adequate patency of the hepatic artery and the occlusion of the pseudoaneurysm.

[An atypical case of massive gastrointestinal hemorrhage].

Gastrointestinal stromal tumors (GIST) are an infrequent cause (<1%) of severe gastrointestinal hemorrhage. Treatment is mainly surgical through complete tumoral resection. We report the case of a 29-year-old woman who presented to the emergency room with severe gastrointestinal bleeding manifested by melena.

Bronchial artery aneurysm treated with aortic stent graft and fibrin sealant.

Bronchial artery aneurysm occurs rarely but can cause a life-threatening hemorrhage when it ruptures. The traditional therapy has been aneurysm resection or transcatheter arterial embolization. We report a case of mediastinal bronchial artery aneurysm which could not be occluded with transcatheter arterial embolization and instead was treated with a thoracic aortic stent graft and embolization with fibrin sealant.

[Utility of arteriography with selective arterial calcium injection for the diagnosis of insulinoma].

Background: Common preoperative imaging techniques for the diagnosis of insulinomas do not lead to an effective localization in 40% cases. We present here our experience with arteriography followed by selective arterial calcium injection (AACI).

Method: Retrospective review of AACIs and other techniques performed in patients with endogenous hyperinsulinism.
