Endovascular stent graft for traumatic splenic vein aneurysm via percutaneous transsplenic access.

Traumatic splenic vein aneurysm (SVA) is an extremely rare entity. Traditionally, treatment varied from noninvasive followup to aneurysm excision with splenectomy. However, there has been no prior report of traumatic SVA treated with endovascular stent graft for SVA via percutaneous transsplenic access.

Percutaneous Aspiration Embolectomy Using Guiding Catheter for the Superior Mesenteric Artery Embolism.

Objective: To evaluate the technical feasibility and clinical outcome of percutaneous aspiration embolectomy for embolic occlusion of the superior mesenteric artery (SMA).

Materials And Methods: Between January 2010 and December 2013, 9 patients with embolic occlusion of the SMA were treated by percutaneous aspiration embolectomy in 2 academic teaching hospitals. The aspiration embolectomy procedure was performed with the 6-Fr and 7-Fr guiding catheter.

New predictive marker for hemodialysis vascular access dysfunction.

To examine the relationship between intra-access pressures and vascular stenosis, we measured the total (pT ) and static (pS ) pressures and the severity of stenosis before and after percutaneous transluminal angioplasty (PTA). The dynamic pressure (△p) and static intra-access pressure ratios (SIAPR) were calculated. We analyzed the clinical correlation of △p and SIAPR with the severity and location of stenosis, and searched potential predictive factors for the severity of stenosis using multivariate regression.

Endovascular revascularization for patients with critical limb ischemia: impact on wound healing and long term clinical results in 189 limbs.

Objective: To evaluate the impact on wound healing and long-term clinical outcomes of endovascular revascularization in patients with critical limb ischemia (CLI).

Materials And Methods: This is a retrospective study on 189 limbs with CLI treated with endovascular revascularization between 2008 and 2010 and followed for a mean 21 months. Angiographic outcome was graded to technical success (TS), partial failure (PF) and complete technical failure.

Percutaneous biliary drainage using open cell stents for malignant biliary hilar obstruction.

Objective: To evaluate the feasibility, safety and the effectiveness of the complex assembly of open cell nitinol stents for biliary hilar malignancy.

Materials And Methods: During the 10 month period between January and October 2007, 26 consecutive patients with malignant biliary hilar obstruction underwent percutaneous insertion of open cell design nitinol stents. Four types of stent placement methods were used according to the patients' ductal anatomy of the hilum.

Hepatocellular carcinomas smaller than 4 cm supplied by the intercostal artery: can we predict which intercostal artery supplies the tumor?

Objective: To predict which intercostal artery supplies a tumor by examining the spatial relationship between hepatocellular carcinoma (HCC) and the intercostal artery feeding the tumor on transverse computed tomography (CT) images.

Materials And Methods: Between January 2000 and September 2009, 46 intercostal arteries supplying HCCs smaller than 4 cm were noted in 44 patients, and CT scans and angiograms of these patients were retrospectively reviewed. The intercostal artery feeding the tumor was marked on the CT scan showing the center of the tumor.

Chemoembolization via branches from the splenic artery in patients with hepatocellular carcinoma.

Purpose: This study was designed to evaluate the radiologic findings and imaging response of chemoembolization via branches of the splenic artery in patients with hepatocellular carcinoma (HCC).

Methods: From January 2001 to July 2010, we observed tumor staining supplied by branches of the splenic artery in 34 (0.6%) of 5,413 patients with HCC.
