Objective: Thoracic aortic dissection (TAD) is associated with matrix changes, biochemical changes, and inflammatory markers like interleukin-1 beta (IL-1β). However, the exact mechanism remains unknown. This study aimed to investigate the role of IL-1β, matrix metalloproteinase (MMP)-2, MMP-9, smooth muscle cell apoptosis, and elastic fibre fracture in the development of TAD in a rat model.

Methods: Characteristics of abdominal aortic aneurysm patients who had challenging proximal aortic neck anatomy (short or angulated) and underwent FS sac filling to resolve TIAE after traditional EVAR in Changhai Hospital between December 2006 and July 2010 were collected and reviewed. Intrasac pressure was measured with a preloaded catheter before and after FS filling to observe the immediate curative effect.
Objectives: Our goal was to examine whether interleukin-1 beta (IL-1β) originates locally and its possible relationship with matrix metalloproteinases (MMPs), apoptosis, elastin fibres and biomechanics in aortic dissecting aneurysms (DAs).
Methods: Aortic DAs were induced in 24 rats with β-aminopropionitrile (BAPN); another 12 rats without BAPN were designated as controls. Then IL-1β levels were measured both in the circulation and in local aortic specimens.

To perform a meta-analysis and examine the use of D-dimer levels for diagnosing acute aortic dissection (AAD). Medline, Cochrane, EMBASE, and Google Scholar were searched until April 23, 2014, using the following search terms: biomarker, acute aortic dissection, diagnosis, and D-dimer. Inclusion criteria were diagnosis of acute aortic dissection, D-dimer levels obtained, 2-armed study.

Methods: From February 2011 to May 2012, 200 patients with great saphenous varicose veins were treated using combined EVLT and PHL. Sixty-eight of them had concurrent TriVex suction.
Background: Spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) is a rare condition often associated with a poor prognosis. The goal of this study is to assess the efficacy of endovascular treatment of SIDSMA with stenting and investigate the possible therapeutic mechanisms involved.
Methods: This is a retrospective review of all patients undergoing endovascular treatment of SIDSMA from January 2009 to December 2011.
Objective: This study aims at evaluating the safety and efficacy of a porous stent system consisting of multiple overlapping uncovered stents in the treatment of complex aortic aneurysms with vital branches.
Methods: Data of all patients with aortic aneurysms treated in our center with multiple overlapping uncovered stents between February 2010 and December 2011 were retrospectively reviewed. Preoperative characteristics, intraoperative details, and follow-up outcomes were documented.
Background: Most of endovascular stent-graft modifications to preserve side branch must be customized according to extensive pre-operative assessment, which may not be possible in many hospitals and emergency settings. The study was to develop a novel stent-grafts system that would allow in situ "fenestration", with less reliance on preoperative imaging.
Methods: The magnitude of pressure difference (PD) between left subclavian artery (LSA) and aortic arch were measured in 12 experimental pigs.
Background: Multilayer stent has become a new endovascular strategy for visceral artery aneurysm repair. However, its use was not allowed in some areas, such as China. This study evaluates an alternative method: multiple overlapping bare stents for repairing visceral artery aneurysms.

Objective: To review the recent progress of multilayer stents in treating arterial aneurysms and to draw an initial conclusion about its paradigm.
Data Sources: PubMed database and ELSEVIER database were searched with the keywords "cardiatis" or "multilayer stent" for relevant articles from January 2008 to September 2012. Relevant websites (provided by Cardiatis) were also involved in the review process.

Objective: To investigate thoracic aortic longitudinal elastic strength in β-aminopropionitrile (BAPN) treated rat model of aortic dissection (AD).
Methods: Twenty-nine young rats (Sprague-Dawley) were divided into tow groups, control group (n = 12) and BAPN group (n = 17). Seventeen rats were treated with 0.

Purpose: To describe a new technique that combines traditional stent graft and multiple overlapping uncovered stents to form a sandwich-like structure in the management of a wide-necked saccular suprarenal aneurysm.
Case Report: An 83-year-old woman was admitted to the hospital with a large symptomatic aortic aneurysm that involved celiac trunk. Traditional stent graft and coiling were precluded due to the anatomical complexity of the aneurysm.
Objective: To clarify the outcome of surgical reconstruction for renal artery in Takayasu arteritis-induced renal artery stenosis (TARAS).
Methods: A retrospective chart review was conducted on 33 consecutive patients with TARAS, who underwent aortorenal bypass (ARB) with autologous saphenous vein graft. There were 9 male and 24 female patients, with a mean age of (25 ± 11) years.
Objectives: To analyze the long-term results of fibrin glue embolization to eliminate type I endoleaks after endovascular aneurysm repair (EVAR), and to assess the feasibility and durability of this technique.
Methods: From August 2002 to June 2010, among the 953 EVAR patients, 51 (5.4%) patients underwent intraoperative transcatheter fibrin glue sac embolization to resolve type I endoleak persisting after initial intraoperative maneuvers to close the leak or in necks too short or angulated for cuff placement.
Background: Chronic venous disorder (CVD) of the lower extremities generally induces dermatologic complications in lower extremity skin, such as hyperpigmentation. If not treated effectively, the lesions may develop into severe outcomes, including dermal ulcer or necrosis.
Objective: To evaluate the clinical efficacy of Mailuo Shutong Granule, a compound traditional Chinese herbal medicine, and Hirudoid cream (heparinoid), in treatment of patients with dermal hyperpigmentation of skin caused by CVD.
Objective: To examine the expression of interleukin-1β and interferon-γ and their possible roles in aortic dissections and aneurysms.
Methods: Aortic specimens were obtained from patients with type I thoracic aortic dissection, ascending thoracic aortic aneurysms, and control organ donors. The expression of interleukin-1β, interferon-γ, matrix metalloproteinase-9, and signal transduction factors phospho-p38 and phosphorylated c-jun N-terminal kinase (phospho-JNK) were detected by real time reverse transcription-polymerase chain reaction (real time RT-PCR), Western blot, and immunohistochemistry, respectively.
Objective: Our previous proteomic research has indicated that some cytoskeleton proteins show differential expression between thoracic aortic dissection and normal control groups, which suggests a possible mechanism involved in the pathogenesis of the vascular remodeling of this disease. This study was to investigate the expression of these cytoskeleton proteins and their possible molecular pathway in the remodeling process of thoracic aortic dissection.
Methods: Ascending aortic segments were obtained from thoracic aortic dissection patients (Debakey type I, n = 13) and age-matched normal donors (n = 8).
Glucocorticoids (GCs) are routinely believed to take effect through genomic mechanisms, which are also largely responsible for GCs' side effects. Beneficial non-genomic effects of GCs have been reported as being independent of the genomic pathway. Here, we synthesized a new type of GCs, which took effect mainly via non-genomic mechanisms.
