Pseudo-Aneurysm Associated with Endovascular Re-Canalization for Internal Carotid Artery Occlusion
No full textInternal carotid artery occlusion (ICAO) is a relative uncommon but important cause of transient ischemic attack ( TIA) and cerebral infarction. The feasibility of endovascular re-canalization has been reported in a recent article. In the present report, we describe a 77-year -old man who received endovascular re-canalization of right ICAO. His clinical symptoms recurred 4 months after the procedure , and follow-up perfusion computed tomography (CT) revealed right hemisphere ischemia. Repeat carotid angiogram showed a large pseudo-aneurysm with narrowed true lumen in the distal cervical carotid artery, most likely resulted from previous re-canalization procedure. A coronary stent was deployed to re- establish patency of the vessel, covering and jailing the orifice of the pseudo-aneurysm. Late pseudo- aneurysm formation should be considered as a potential complication after endovascular re-canalization of ICAO
Long-Term Outcome of Percutaneous Coronary Intervention for Unprotected Left Main Coronary Artery Disease
No full textOBJECTIVES: The aim of this study is to evaluate the in- hospital, 30 day and long-term outcomes after percutaneous coronary intervention for unprotected left main coronary artery disease. BACKGROUNDS: Left main coronary artery (LMCA ) diseases stenosis is a strong indication for coronary artery bypass grafting (CABG). With improved device technology, percutaneous coronary intervention (PCI) with drug-eluting stent (DES) stents had been recently advocated as an alternative procedure for the unprotected LMCA disease . METHODS: Between January 2003 and February 2007 , all unprotected LMCA PCI procedures were retrospectively collected. Outcomes were obtained by chart record review and telephone interview. RESULTS: Fifty five consecutive patients with >50% diameter stenosis of LMCA undergoing PCI were analyzed. Indications for a percutaneous strategy were prohibitive surgical risks, or patient/physician preference. The procedural success rate was 98%. 41 patients (75%) received DES implantation. The majority of cases (n=33) were treated with a double- stent strategy. There were no in- hospital deaths. The clinical follow-up time was 867+/-410 days (range 20-1715). 18 (29%) patients experienced major adverse cardiac events, including 3 (5%) deaths, 4 (7%) myocardial infarctions, and 12 (21.8%) target lesion revascularizations (TLR) during follow-up. Multivariate analysis revealed hyperlipidemia (Hazard ratio, HR =6.2, p=0. 024) and bifurcation involvement (HR=4.4, p=0.008) were independent predictors for MACE. CONCLUSIONS: Our results showed that PCI with stenting was an acceptable treatment option for patients with LMCA stenosis. Involvement of the LMCA bifurcation remains a predictor for unfavorable outcome
The political role of the people's liberation army 1949-1973
Full text linkThis thesis is to study the political role of the People's Liberation Army from the approach of structure and function. The framework of the thesis consists of three major parts, first, the influence of Chinese traditional political culture on, and the formation of, the political role of the PL A; second, the influence of domestic political struggles and external military conflicts on the development of the political role of the PLA; and the third, the analysis of the transition of the PLA's political role from the structure and personnel arrangements of the CCPCC Within the above-mentioned three scopes, this thesis make a thorough discussion on the following: (1) The relationship between the structure of the PRC and the formation of the PLA's political role; (2) How has ideology influenced the army's political role; (3) What is Mao's viewpoint and his influence on the development of the army's political role; (4) What is the link between the army and the party, and how has this developed; (6) What accounts for the expansion of the PLA's political functions; (7) What is the influence of political factional struggles on the PLA's political role; (8) Is it political institution or military institution that controls the recruitment of the military elite; (9) What are the disparities between the military elite in handling international conflicts and what are their political considerations; (10) What is the Party's position in the army; (11) How have the Party’s important meetings and personnel arrangements influenced the rise and fall of the PLA's political role

Endovascular Management of Post-Traumatic Innominate Artery Transection with Pseudo-Aneurysm Formation
No full textAlthough catheter-based endovascular techniques have been used with increasing frequency for the management of vascular trauma, reports about innominate artery repair were limited. Here we describe a case of blunt traumatic injury with innominate artery transection. Endovascular stent- graft deployment through femoral artery was performed successfully without any neurologic deficit. (C) 2008 Wiley- Liss, Inc
