1/57. Progressive pulmonary autograft root dilatation and failure after Ross procedure.We present a case of progressive pulmonary autograft root dilatation and subsequent failure after a Ross procedure. The explanted autograft vessel wall revealed striking histologic findings indicative of chronic media rupture. Examination of another explanted pulmonary autograft root showed similar histologic changes, suggesting a common phenomenon in pulmonary autograft roots. It may be the cause of progressive root dilatation as observed after Ross operations.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/57. Dieulafoy's lesion of the jejunum.Dieulafoy's lesion is a rare vascular anomaly but a potentially life-threatening disease. This lesion can also be found in the small intestine, which can be diagnosed only by angiography. However, the angiography may be normal when the bleeding is inactive. We report a case of jejunal Dieulafoy's lesion with a repeated attack of massive gastrointestinal bleeding with a normal initial angiography. The pathological examination found an unusual picture as a dilated submucosal vessel protruded like a submucosal tumor.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/57. Synchronous carcinoma of the gallbladder in a patient with intrahepatic bile duct carcinoma.An 83-year-old woman, diagnosed as having cholelithiasis, was admitted to the Department of Surgery, Nippon Medical School, with right hypochondrial pain. ultrasonography and computed tomography revealed a mass in the gallbladder fundus and a hypovascular tumor in the anterior segment of the liver. magnetic resonance imaging showed stenosis of the intrahepatic bile duct and dilatation of its proximal portion. She was diagnosed as having intrahepatic bile duct carcinoma combined with gallbladder carcinoma. At laparotomy, there was evidence of multiple peritoneal metastases and intraoperative histological examination of the gallbladder tumor revealed adenocarcinoma. Accordingly, only cholecystectomy and needle biopsy of the liver tumor was performed. Histological examination of the gallbladder revealed papillary adenocarcinoma invading the muscularis propria with medullary growth or intermediate stroma. There was no microvessel invasion, no perineural invasion and no lymph node involvement. On the other hand, the liver tumor was a cholangiocarcinoma with a well-differentiated tubular pattern. Therefore, this was a rare case of synchronous carcinoma of the gallbladder associated with intrahepatic bile duct carcinoma.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/57. Transluminal extraction catheter atherectomy for the treatment of acute occlusion of an ectatic coronary artery.Thrombotic occlusion of an ectatic coronary artery may not respond to thrombolytic therapy or balloon angioplasty, since the infarct-related vessel contains a significant amount of thrombus. A patient with acute myocardial infarction of an ectatic right coronary artery that was occluded by a heavy clot burden is described. The patient was treated successfully with transluminal extraction catheter atherectomy and results were confirmed by intravascular ultrasound.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/57. Clinical significance of coronary arterial ectasia.In a study group of 2,457 consecutive patients undergoing cardiac catheterization, 30 patients had coronary arterial ectasia, an irregular dilatation of major vessels up to seven times the diameter of branch vessels. The frequency of hypertension, abnormal electrocardiogram and history of myocardial infarction was greater than that in a control group with obstructive coronary artery disease. patients with ectasia did not differ from patients with obstructive disease in sex, age, prevalence of angina or presence of metabolic abnormalities. Six deaths occurred in the group with ectasia during a mean follow-up period of 24 months (annual rate of 15 percent). Extensive destruction of the musculoelastic elements was evident, resulting in marked attenuation of the vessel wall. The short-term prognosis in this group is the same as in medically treated patients with three vessel obstructive coronary artery disease.- - - - - - - - - - ranking = 4keywords = vessel (Clic here for more details about this article) |
6/57. Multiple coronary artery aneurysms combined with abdominal aortic aneurysm.Coronary artery aneurysm (CAA) is defined as coronary dilatation which exceeds the diameter of a normal adjacent segment or the diameter of the patients's largest coronary vessel by as much as 1.5 times. It is an uncommon pathology with a frequency of 1-4% in routine autopsies or coronary angiographies. atherosclerosis plays an important role in the development of CAA, and it may be a predominant cause in the majority of patients. However, the timing of surgical intervention and the treatment options for CAA are still controversial. In this report, we present a patient who had multiple CAAs of all main coronary arteries and abdominal aortic aneurysm. Different treatment modalities and indications are also discussed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/57. Familial multiple trichoepithelioma associated with subclavian-pulmonary collateral vessels and cerebral aneurysm--case report.A 63-year-old woman presented with cerebellar infarction caused by occlusion of the right posterior inferior cerebellar artery. She had papules on her face that were identified histologically as multiple trichoepithelioma. angiography revealed right subclavian-pulmonary collateral vessels and a cerebral aneurysm arising from the bifurcation of the right middle cerebral artery. Her grandmother, mother, and uncle had had similar papules, and the deaths of her mother and uncle were due to subarachnoid hemorrhage.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
8/57. wiskott-aldrich syndrome, vasculitis and critical aortic dilatation.wiskott-aldrich syndrome is a rare X-linked disorder, comprising the triad eczema, thrombocytopenia and progressive immunodeficiency. The prognosis has been poor in the past but is now improving with therapeutic options including splenectomy and bone marrow transplantation. We report the case of a 21-year-old male with an established diagnosis of wiskott-aldrich syndrome, who developed aortic root dilatation with severe aortic regurgitation requiring aortic valve and root replacement. histology confirmed a destructive, full-thickness, chronic aortitis. CONCLUSION: As treatment and prognosis improve, large vessel vasculitis may become an increasingly recognized late complication of this syndrome, which now extends into adult practice.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/57. Platelet glycoprotein IIb/IIIa receptor blockade with integrilin (eptifibatide) for early postinfarction angina in a patient with coronary arterial ectasia.A middle-aged male with multivessel proximal coronary ectasia presented with thrombosis-related acute myocardial infarction and early postinfarct angina, and was successfully treated with a combination of intravenous integrilin (eptifibatide) and unfractionated heparin. The possible aetiology, prognosis and available management strategies are discussed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/57. Severe coronary ectasia and tortuosity--an unpleasant finding during percutaneous revascularization in acute coronary syndrome.Percutaneous coronary revascularization plays an important role in the management of acute coronary syndrome. Unpredictable angiographic findings of severe coronary ectasia and tortuosity may, however, compromise the otherwise high and predictable success rates of this intervention. We report on two patients with acute coronary syndrome in whom difficult anatomy precluded successful percutaneous recanalization of the culprit vessel.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
