1/68. Acute occlusion of the left main coronary artery following intracoronary ultrasound examination.Intracoronary ultrasound (ICUS) is generally considered as safe procedure, with a low complication rate. We describe a nearly fatal complication of a diagnostic ICUS study that was treated successfully with stent implantation in the left main coronary artery and discuss the indications and remaining risks of this procedure.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/68. Successful Wallstent implantation for extensive iatrogenic renal artery dissection in a patient with fibromuscular dysplasia.PURPOSE: To describe a case of renal artery stenosis with fibromuscular dysplasia (FMD) and extensive iatrogenic dissection treated with Wallstent implantation. methods AND RESULTS: An 83-year-old woman with a history of coronary artery disease and hypertension presented at another facility with exertional angina and poorly controlled hypertension. Renal arteriography uncovered a critical right renal artery stenosis with severe FMD. However, angioplasty resulted in extensive dissection of the renal artery, for which the patient was referred to our institution. The renal artery was recanalized via the left brachial approach with restoration of flow using a Wallstent and a Palmaz stent. The patient's blood pressure was controllable after this procedure, and follow-up duplex imaging with flow velocities at 6 months showed patent right renal artery stents. CONCLUSIONS: Owing to its length and flexibility, the Wallstent endoprosthesis was a useful treatment modality in this case of extensive renal artery dissection.- - - - - - - - - - ranking = 0.1keywords = coronary (Clic here for more details about this article) |
3/68. rupture of several parasagittal bridging veins without subdural bleeding.This case reports on a fatal craniocerebral trauma involving numerous ruptured cerebral bridging veins that did not bleed subdurally, despite approximately 15 hours of survival. A 15-year-old girl was severely injured as the passenger of a car that crashed sideways into a tree. She-suffered a cerebral trauma of the "diffuse injury" type and was unconscious after the accident. Her computed tomographic scan at admission showed massive brain edema, axial herniation, and marked hypodensity of the bilateral carotid flow area. Despite intensive care measures, the clinical course was characterized by central decompensation with therapy-resistant cardiocirculatory insufficiency. The autopsy revealed ruptures of numerous parasagittal bridging veins. The injured vessels were not thrombosed, and yet there was absolutely no subdural bleeding. This unusual combination of findings is assumed to be caused by an isolated collapse of cerebral circulation occurring shortly after the accident and primarily attributed to a rapid increase of intracranial pressure.- - - - - - - - - - ranking = 0.0020330187548071keywords = circulation (Clic here for more details about this article) |
4/68. Repair of left anterior descending coronary artery perforation by magic Wallstent implantation.Coronary rupture is a rare complication of percutaneous coronary intervention. However, it may be associated with serious hemodynamic consequences often leading to tamponade, myocardial infarction, emergency surgical intervention, or death. We report a successful percutaneous repair of a brisk left anterior descending coronary artery perforation by the implantation of a magic Wallstent.- - - - - - - - - - ranking = 0.6keywords = coronary (Clic here for more details about this article) |
5/68. Gelfoam embolization of a distal coronary artery guidewire perforation.A guidewire-induced distal coronary artery perforation presenting with cardiac tamponade was occluded by distal Gelfoam embolization via an infusion catheter.

6/68. Successful treatment of coronary artery perforation during angioplasty using a new membrane-coated stent.We report a case of successful treatment of coronary artery perforation and cardiac tamponade, which developed during percutaneous transluminal coronary angioplasty, with a PTFE-coated stent. Intravascular ultrasound was first used to overcome the shortcomings of conventional angiography and overlapping of a conventional stent was not as effective as coated-stent placement in sealing a further leakage. Thus, PTFE-coated stents may be an effective alternative to emergency surgery or autologous venous covered stenting and should be considered when coronary artery perforation occurs.- - - - - - - - - - ranking = 0.7keywords = coronary (Clic here for more details about this article) |
7/68. Sudden deterioration of aortic regurgitation due to rupture of a raphal cord on the conjoined cusp.A 57-year-old man was admitted to hospital for acute myocardial infarction associated with mild aortic regurgitation, which was successfully treated by intracoronary thrombolysis. Twenty-four days later, he suffered from another chest pain attack without any electrocardiographic ST-T changes. The coronary angiogram did not show any significant lesions, but the aortic root angiogram showed massive aortic regurgitation. Surgery revealed a bicuspid aortic valve with a conjoined cusp that had a fenestrated raphe torn away from the aortic wall and prolapsing into the left ventricle. The aortic valve was successfully replaced with a St Jude Medical mechanical valve prosthesis. The pathological significance of the intact raphal cord and the rupture remains an unsolved problem. This is the first reported case in which an increase of aortic regurgitation due to a ruptured raphal cord supporting the conjoined cusp was confirmed by a serial root angiogram.- - - - - - - - - - ranking = 0.2keywords = coronary (Clic here for more details about this article) |
8/68. Successful sealing of perforation of saphenous vein graft by coronary stent.Coronary artery perforation is a rare occurrence during angioplasty and could lead to major complications requiring emergency surgical intervention. We describe a case of perforation of a saphenous vein graft during stenting. The perforation was successfully sealed by a second coronary stent.- - - - - - - - - - ranking = 0.5keywords = coronary (Clic here for more details about this article) |

Successful treatment of coronary artery perforation in an abciximab-treated patient by microcoil embolization.We describe a case of type 2 coronary artery perforation in a 73-year-old man undergoing coronary artery rotablation and stenting with abciximab therapy. The coronary artery perforation was successfully treated by coil embolization with Trufill pushable coils made from platinum alloy and synthetic fibers to promote maximum thrombogenicity.- - - - - - - - - - ranking = 0.7keywords = coronary (Clic here for more details about this article) |
