The cardiovascular lesions in 34 cases of Marfan's syndrome which were studied post mortem are reviewed. Recent reports show that the most common and most important lesion is cystic necrosis of the media which results in aneurysmal formations of the ascending aorta. The aneurysm may be fusiform and the aortic ring dilated, producing a marked aortic insufficiency, or there may be a dissecting an...
Acute aortic dissection is a common disease caused by primary tear in the aortic intima or rupture of vasa vasorum. Every year 5-30 per million are affected by that. Untreated aortic dissection (dissecting aortic aneurysm) carries a high mortality rate. More than 90% of acute dissections present with acute pain in chest or back or both. Aortic dissection may mimic other more common conditions...
Methods Based on a computed tomography angiography of the aorta, we made a delrin ring, keeping the anatomical characteristics of the aortic annulus. A matrix one following we made from stainless steel with the shape of the three cusp aortic valve, followed by preparation of the injection of liquid polyurethane segmented (SPU), using a esterolitografia technique. In vitro tests: The materials u...
The presence of signet-ring cells in an endometrial adenocarcinoma is extremely uncommon and it is always necessary to rule out a metastatic neoplasm. We report a FIGO grade 2 endometrial carcinoma with a signet-ring cell component found in the curettage performed to a 53-year-old woman. The neoplastic proliferation was also found in the endometrium of the radical hysterectomy with bilateral sa...
Background: Balloon valvuloplasty is a relatively new technique for relief of obstruction of aortic valve. The primary results of this procedure are similar to surgical valvotomy with fewer complications and mortality. Materials and methods: One hundred fifty-five patients with congenital aortic stenosis were enrolled in this study over a period of 6 years (1991-1997). Participants were all un...
BACKGROUND Management of patients with acquired heart malformations, including aortic valve disease, is still challenging. Due to ageing of population, patients undergoing valve surgery are older than in the past. The 3F Therapeutics, conducting a programme of construction of heart valves for transarterial or transapical implatation, prepared the 'Enable' bioprosthetic valve for sutureless inse...
We report a case of a 64 year old woman with a calcified ring at the level of the sinotubular junction. Echocardiography and Computed Tomography showed a supravalvular aortic stenosis, without known associated lesions, except for the existence of an aberrant right subclavian artery. These combination of abnormalities makes it an unique case. Differential diagnosis of sinutubular calcification i...
Primary signet ring cell carcinoma of the cervix is extremely rare. A 47-year-old woman visited for postcoital vaginal bleeding during the last six months. Gynecologic examination revealed mild cervical erosion and touch bleeding. Colposcopic punch biopsy revealed a signet ring cell type of mucinous adenocarcinoma. The patient underwent radical hysterectomy with bilateral salpingooophorectomy, ...
Introduction: Abdominal aortic aneurysm is a multifactorial condition which associated with aging and atherosclerosis. During aneurysm surgery, hypotension after aortic clamp removing occure commonly that require specific treatments. This case report showes administration of blood and hemodynamic control methods after aortic unclumping during aortic aneurysm surgery. Patient: A 75–years-o...
