  • Treatment of Visceral Aneurysm Using Multilayer Stent: Two-Year Follow-Up Results in Five Consecutive Patients
    CardioVascular and Interventional Radiology, 2013
    Co-Authors: Alberto Balderi, Alberto Antonietti, Fulvio Pedrazzini, Davide Sortino, Claudia Vinay, Maurizio Grosso
    Abstract:

    Purpose The present study was performed to analyze the midterm results (five consecutive patients, 2-year follow-up) of the endovascular management of Visceral artery Aneurysms using the Cardiatis Multilayer Flow Modulator (CMFM) (Cardiatis, Isnes, Belgium), a self-expandable stent. Materials and Methods From August 2009 to January 2011, we implanted five CMFMs in five patients (all men; mean age 73 years) to treat two common hepatic artery Aneurysms, one celiac trunk Aneurysm, one splenic artery Aneurysm, and one superior mesenteric artery Aneurysm (diameter 25–81 mm). The primary end point was technical success. The secondary end point was stent patency, absence of Aneurysm rupture or reperfusion, and shrinking of the sac at 6-, 12-, and 24-month follow-up using computed tomography angiography. Follow-up ranged from 24 to 48 months (mean 31.2). Results Technical success was achieved in all patients. Complete exclusion of the Aneurysm with sac shrinking was achieved in two patients. Two stents became occluded at 6- and 24-month follow-up, respectively; both patients were asymptomatic and were not retreated. One patient developed sac reperfusion due to incomplete Aneurysm exclusion. Conclusion Long-term results in a wider population are needed to validate the effectiveness of the CMFM.

  • Endovascular Treatment of Splenic Artery Aneurysm With a Stent-Graft: A Case Report.
    Medicine, 2015
    Co-Authors: Li-jun Guang, Qiang Huang, Jianfeng Wang, Renyou Zhai
    Abstract:

    Splenic artery Aneurysm, one of the most common Visceral Aneurysms, accounts for 60% of all Visceral Aneurysm cases. Open surgery is the traditional treatment for splenic artery Aneurysm but has the disadvantages of serious surgical injuries, a high risk of complications, and a high mortality rate.We report a case who was presented with splenic artery Aneurysm. A 54-year-old woman complained of upper left abdominal pain for 6 months. An enhanced computed tomography scan of the upper abdomen indicated the presence of splenic artery Aneurysm. The splenic artery Aneurysm was located under digital subtraction angiography and a 6/60 mm stent graft was delivered and released to cover the Aneurysm. An enhanced computed tomography scan showed that the splenic artery Aneurysm remained well separated, the stent graft shape was normal, and the blood flow was unobstructed after 1 year.This case indicates a satisfactory efficacy proving the minimal invasiveness of stent graft exclusion treatment for splenic artery Aneurysm.

  • stent graft repair of Visceral artery Aneurysms
    Journal of Vascular Surgery, 2002
    Co-Authors: Robert Larson, Jeffrey A Solomon, Jeffrey P Carpenter
    Abstract:

    Endovascular techniques with coil embolization have been used in certain Visceral Aneurysm cases, often resulting in sacrifice of the involved Visceral vessel and end-organ thrombosis. We describe two cases in which stent grafts were used to treat these Aneurysms, allowing preservation of Visceral artery and end-organ flow while completely excluding the Aneurysm. Case 1 was a 50-year-old morbidly obese woman with a history of multiple abdominal operations for renal cell carcinoma who was found to have a large splenic artery Aneurysm. A 12-mm x 50-mm Wallgraft endoprosthesis (Boston Scientific, Watertown, Mass) was placed across the Aneurysm from a femoral approach. The Aneurysm was completely excluded, and splenic artery flow was preserved. A subsequent computed tomographic scan showed complete Aneurysm exclusion and preserved flow to the spleen. Case 2 was a 73-year-old man with hypertension with back pain who was found with computed tomographic scan to have an 8-cm hepatic artery Aneurysm. Arteriography showed a large saccular Aneurysm arising from the mid portion of the common hepatic artery. Two 5-mm x 26-mm Jostent stent grafts (Jomed, Alpharetta, Ga) were placed across the Aneurysm neck, completely excluding the Aneurysm and preserving hepatic artery flow. The patient became pain free, and subsequent duplex ultrasound scan showed a thrombosed Aneurysm with normal hepatic artery flow. Stent graft techniques show early promise as a safe and effective treatment of Visceral artery Aneurysms in selected patients at high risk. Endografts, unlike coil embolization, exclude the Aneurysm and preserve end organ perfusion. Determining the durability of this type of therapy will require further study.

  • Hepatic artery Aneurysm.
    The British journal of radiology, 1999
    Co-Authors: D. O'driscoll, S. P. Olliff, J. F. C. Olliff
    Abstract:

    Hepatic artery Aneurysms (HAAs) are rare. A review of the English language literature from 1985 to 1995 for reports of Visceral artery Aneurysms showed HAA to be the most frequently reported Visceral Aneurysm during that decade. This increase in incidence relates to the increasing use of percutaneous diagnostic and therapeutic procedures. A second factor is the increased use of diagnostic CT scanning after blunt liver trauma. The purpose of this pictorial review is to illustrate the imaging presentation and radiological management of HAAs.
