Two-stage endovascular repair for concurrent penetrating atherosclerotic ulcers of the thoracic and abdominal aorta.

We report a case of concurrent saccular aneurysms caused by a penetrating atherosclerotic ulcer of the thoracic and abdominal aorta that were successfully treated by staged endovascular repair. Even though surgical open repair or endovascular repair is the treatment option, use of endovascular repair is now accepted as an alternative treatment to surgery in selected patients. To prevent contrast medium-induced nephropathy and spinal cord ischemia caused by a simultaneous endovascular procedure, a saccular aneurysm of the descending thoracic aorta was excluded by stent graft, followed by the placement of a bifurcated stent graft in the infrarenal abdominal aorta one month later.

The results of aspiration thrombecomy in the endovascular treatment for iliofemoral deep vein thrombosis.

Purpose: The aim of this study is to evaluate the results of aspiration thrombectomy (AT) in the endovascular treatment for iliofemoral deep vein thrombosis (DVT) through the comparison of catheter directed thrombolysis (CDT) alone group and CDT with AT group.

Methods: From November 2001 to April 2011, 100 patients received endovascular treatment with CDT alone or CDT with AT for iliofemoral DVT at Yeungnam University Medical Center. We compared procedure, clinical outcomes and complications between the two groups.

Tacrolimus related neurologic complication after pediatric kidney transplantation.

Recently significant neurotoxicity has been reported with the use of carcineurin inhibitors. An 11-year-old-girl had undergone a transplantation of kidney from her mother. On post-operative day 12, hypertension, headache, and left motor weakness (grade I) suddenly occurred.

Adventitial cystic disease of common femoral vein.

Adventitial cystic disease (ACD) of venous system is an extremely rare condition. Very few reports of ACD in venous system have been described. In this report we discuss two cases of common femoral vein ACD that presented with a swollen leg by the obstruction of the vein.

The early and mid-term results of carotid artery stenting in high-risk patients.

Purpose: This study aimed to investigate early and mid-term outcomes of carotid artery stenting (CAS).

Methods: We retrospectively reviewed 111 patients who were treated for carotid stenosis between October 2004 and December 2009 (42 CASs and 69 carotid endarterectomies [CEAs]).

Results: CAS group was older than CEA group (70 years vs.

Cilostazol Inhibits Vascular Smooth Muscle Cell Proliferation and Reactive Oxygen Species Production through Activation of AMP-activated Protein Kinase Induced by Heme Oxygenase-1.

Cilostazol is a selective inhibitor of phosphodiesterase 3 that increases intracellular cAMP levels and activates protein kinase A, thereby inhibiting vascular smooth muscle cell (VSMC) proliferation. We investigated whether AMP-activated protein kinase (AMPK) activation induced by heme oxygenase-1 (HO-1) is a mediator of the beneficial effects of cilostazol and whether cilostazol may prevent cell proliferation and reactive oxygen species (ROS) production by activating AMPK in VSMC. In the present study, we investigated VSMC with various concentrations of cilostazol.

Carotid artery revascularization in patients with concomitant carotid artery stenosis and asymptomatic unruptured intracranial artery aneurysm.

Background: The incidence of concomitant carotid artery stenosis and unruptured intracranial aneurysm (UIA) has been reported to be between 3% and 5%. The rupture risk of UIA measuring <7 mm is very low according to International Study of Unruptured Intracranial Aneurysm data. However, there may be a potential risk of aneurysm rupture after carotid artery revascularization because of increased cerebral blood flow.

Changing pattern of surgical revascularization for critical limb ischemia over 12 years: endovascular vs. open bypass surgery.

Objective: This study is a review and evaluation of our 12-year experience of revascularization for critical limb ischemia (CLI) with angioplasty/stenting and bypass surgery to identify specific trends of procedure volume and outcomes in this particular group.

Methods: Endovascular and open bypass procedures done for CLI by a single surgeon between 1993 and 2004 were evaluated retrospectively. Thrombolysis and thrombectomy procedures done as the only revascularization procedure were excluded from analysis.

Association of anti-obesity activity of N-acetylcysteine with metallothionein-II down-regulation.

People with upper body or visceral obesity have a much higher risk of morbidity and mortality from obesity-related metabolic disorders than those with lower body obesity. In an attempt to develop therapeutic strategies targeting visceral obesity, depot- specific differences in the expression of genes in omental and subcutaneous adipose tissues were investigated by DNA array technology, and their roles in adipocyte differentiation were further examined. We found that levels of metallothionein-II (MT-II) mRNA and protein expression were higher in omental than in subcutaneous adipose tissues.
