1/24. Multivessel spontaneous coronary artery dissection in a patient with severe systolic hypertension: a possible association. A case report.Spontaneous coronary artery dissection (SCAD) is an uncommon cause of myocardial ischemia and infarction. hypertension has not been associated with SCAD. The authors report multivessel SCAD in an elderly woman with severe systolic hypertension. They postulate that hypertension of this degree may play a pathophysiologic role in the causation of SCAD.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/24. Usefulness of coronary MR angiography prior to angioplasty.The range of indications for percutaneous transluminal coronary angioplasty (PTCA) has increased greatly since the procedure was initially introduced. The success rate depends on the anatomy and length of the occlusion and on the state of the distal vessel. We present a case where the use of magnetic resonance angiography (MRA) allowed to evaluate the length of a subtotal occlusion prior to PTCA, and thus could have had an impact on therapeutic decisions. Coronary MR angiography is one of the many applications of breathhold MRI, where breathholding and segmented k-space acquisition are combined to provide anatomical images of coronary vessels. Coronary MR angiography allows reproducible visualization of coronary vessels. Even under adverse circumstances (poor cardiac triggering) the images are sometimes of sufficient quality to help make a diagnosis. This capability may increase the as yet limited clinical use of MR technology in the practice of cardiology.- - - - - - - - - - ranking = 0.6keywords = vessel (Clic here for more details about this article) |
3/24. Bullosis diabeticorum in a newly discovered type 2 diabetes mellitus.Bullosis diabeticorum (BD), although a rare manifestation, is characteristic of diabetes mellitus. The exact origin of BD is unknown. We report another case of a 54-year-old man who developed a blistering lesion on his left leg. Histopathological examination revealed a microangiopathy with hyalinosis of the blood vessel walls.- - - - - - - - - - ranking = 1.0996300340983keywords = blood vessel, vessel (Clic here for more details about this article) |
4/24. Case 1. diabetes mellitus.A sedentary 60-year-old man newly diagnosed with diabetes insists on seeing a cardiologist because he has read that diabetes damages blood vessels. Several questions submitted by participants and the corresponding answers (based on group discussion and on the actions taken for the real patient) are presented.- - - - - - - - - - ranking = 1.0996300340983keywords = blood vessel, vessel (Clic here for more details about this article) |
5/24. Case report. Mycotic arteritis due to aspergillus fumigatus in a diabetic with retrobulbar aspergillosis and mycotic meningitis.A 74-year-old man with diabetes mellitus type II, retinopathy and polyneuropathy suffered from exophthalmus, ptosis and diplopia. magnetic resonance imaging and computer tomography showed a space-occupying process in the right orbital apex. An extranasal ethmoidectomy accompanied by an orbitotomia revealed the presence of septated hyphae. aspergillus fumigatus was grown from the tissue. After surgical removal of the fungal masses, therapy with amphotericin b (1 mg kg(-1) body weight) plus itraconazole (Sempera, 200 mg per day) over 6 weeks was initiated. Five months later the patient's condition deteriorated again, with vomiting, nausea and pain behind the right eye plus increasing exophthalmus. Antifungal therapy was started again with amphotericin b and 5-fluorocytosine. neutropenia did not occur. The patient became somnolent and deteriorated, a meningitis was suggested. Aspergillus antigen (titre 1:2, Pastorex) was detected in liquor. Anti-Aspergillus antibodies were not detectable. Both the right eye and retrobulbar fungal masses were eradicated by means of an exenteratio bulbi et orbitae. However, renal insufficiency and an apallic syndrome developed and the patient died. At autopsy, a mycotic aneurysm of the arteria carotis interna dextra was detected. The mycotic vasculitis of this aneurysm had caused a rupture of the blood vessel followed by a massive subarachnoidal haemorrhage. In addition, severe mycotic sphenoidal sinusitis and aspergillosis of the right orbit were seen, which had led to a bifrontal meningitis.- - - - - - - - - - ranking = 1.0996300340983keywords = blood vessel, vessel (Clic here for more details about this article) |
6/24. Three-dimensional analysis of a calciphylaxis plaque: clues to pathogenesis.BACKGROUND: calciphylaxis is a rare, life-threatening disorder associated with chronic renal failure, presenting with ulcerating plaques leading to death by sepsis in 60% of patients. Calcification of subcutaneous arterioles, thromboses, and extravascular calcification have been demonstrated in incisional biopsy specimens. However, the sequence of these pathologic events is unknown. OBJECTIVE: We examined a calciphylaxis plaque to document the wave of pathologic change from its center to its periphery. methods: A calciphylaxis plaque was excised postmortem from a female patient. It was examined histologically along 12 radii from the center of the lesion to its periphery. RESULTS: Calcification of small subcutaneous vessels was present in all histologically abnormal sections and extended further peripherally than extravascular calcification by up to 3.0 cm and further than subcutaneous thrombosis by up to 1.5 cm. CONCLUSION: Vascular mural calcification is an early and essential process in the development of a calciphylaxis plaque.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
7/24. Mononeuritis multiplex in diabetes mellitus: evidence for underlying immune pathogenesis.Four patients with type 2 diabetes mellitus developed mononeuritis multiplex subacutely. sural nerve biopsies showed multifocal axonal loss in all patients, with epineurial perivascular inflammation affecting small calibre vessels in three. Three patients improved with immunotherapy. These observations suggest that mononeuritis multiplex in diabetes may be caused by an immune mediated vasculopathy and that it is pathogenetically akin to the more common and better recognised diabetic amyotrophy.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
8/24. Pseudodoubling of the optic disc: a colour Doppler imaging study.Pseudodoubling of the optic disc is a rare clinical presentation. In these cases it is necessary to exclude retinal coloboma or atrophy following vascular or infectious diseases. We present a case of pseudodoubling of the optic disc in a woman with type 2 diabetes and arterial hypertension. Ophthalmoscopic examination of the fundus showed a disc-like lesion in the right eye and a diabetic retinopathy in the left eye. The lesion was evaluated with fluorescein angiography, neuroradiological and colour Doppler imaging investigations. Colour Doppler imaging confirmed the angiographic findings of anomalous vascularisation of the pseudopapilla and provides an analysis of the choroidal vessel anastomosis between the optic disc and the retinal lesion, revealing that the pseudodoubling in this patient was the result of a chorioretinal coloboma.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
9/24. Delayed recovery of left ventricular function after recanalization of a chronic coronary occlusion.An unusually prolonged course of recovery of severely impaired left ventricular (LV) function (EF 32%) was observed in a patient after recanalization of a chronically occluded LAD. Despite persistent vessel patency, LV function remained depressed for almost 2 years after the percutaneous transluminal coronary angioplasty until complete recovery (EF 82%) could be observed. The possibility of a delayed recovery should be considered when assessing new therapeutic strategies to improve LV function of chronically ischemic myocardium.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
10/24. A male with angioimmunoblastic T-cell lymphoma and proliferative glomerulonephritis.In this article we present the case report of a 67-year-old male with a nephrotic syndrome due to a proliferative glomerulonephritis, associated with an angioimmunoblastic T-cell lymphoma. diagnosis was made on an axillary lymph node biopsy and showed expanded T-cell areas with multiple blood vessels, small mature lymphocytes, eosinophils, and plasma cells. A kidney biopsy was suggestive for a proliferative glomerulonephritis with intra- and extracapillary proliferation. Hypercellular glomeruli were seen, as well as multiple floride crescents. Interstitial edema and fibrosis were absent. Immunohistochemical reactions were negative; there was some mesangial reaction with IgM in the glomeruli. Treatment with high-dose corticosteroids was initiated, with clinical improvement, and was immediately followed by therapy with cyclophosphamide, hydroxydaunomycin, vincristine, and prednisone (CHOP), which induced complete remission with a follow-up of 1 year. To our knowledge, the association of angioimmunoblastic T-cell lymphoma and proliferative glomerulonephritis has only been described twice. It concerned elderly men who developed acute renal failure a couple of months after the diagnosis of an angioimmunoblastic T-cell lymphoma. In both, immunoglobulin-containing dense deposits within glomeruli were observed, which was not the case in our patient, where only some mesangial colorization of the IgM in the glomeruli was seen.- - - - - - - - - - ranking = 1.0996300340983keywords = blood vessel, vessel (Clic here for more details about this article) |
