1/25. Catheter-based techniques for closure of coronary fistulae.This study details different methodologies of percutaneous closure of arteriosystemic and arteriovenous coronary fistula. Seven patients underwent transcatheter intervention of 10 fistulas, with 7 fistulas successfully closed: 6 with embolic coil devices and 1 with a covered stent obstructing the fistula ostium. The major complication encountered was one death as a result of device recoil into a major epicardial vessel. Percutaneous transcatheter closure of coronary fistulas appears to be simple, facile, and effective. However, device recoil into an undesired arterial segment, while irritating in a noncoronary arterial tree, may be catastrophic when occurring in an epicardial coronary artery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/25. Histopathologic study of presumed parafoveal telangiectasis.PURPOSE: To report the postmortem histopathologic features that closely resemble the clinical features of parafoveal telangiectasis. methods: light and electron microscopy. RESULTS: Histopathologic features included macular edema; telangiectatic vessels; retinal, subretinal, and superficial retinal neovascularization; retinal pigment epithelial hyperplasia around neovascular aggregates; retinal-choroidal vascular anastomosis; and superficial pigmented cells with lipofuscin. CONCLUSION: The postmortem histopathologic findings in a 36-year-old woman with down syndrome and other systemic conditions correlate with features noted in previous reports of presumed parafoveal telangiectasis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/25. The anastomotic artery connecting the axillary or brachial artery to one of the forearm arteries.A vessel connecting the axillary or brachial artery to one of the forearm arteries was found in a 65 year old male cadaver, during the gross anatomy dissection of the upper extremity of 20 adult cadavers at the Department of Cellular biology and anatomy, louisiana State University Medical Center. The right radial artery originated from the brachial artery nearly at the usual level and was connected to the axillary or brachial artery by a long slender anastomotic artery (vasa aberrantia). The anastomotic artery coursed under the medial side of the biceps muscle between the median and musculocutaneous nerves, and gave off two muscular branches to the biceps muscle. The anastomotic artery coursed between the median and musculocutaneous nerves in the arm, it passed to the forearm under the bicipital aponeurosis and connected the main radial artery on the radial side of the forearm. The anastomotic artery can be explained on the basis of its embryologic development and also ought to be distinguished from the other common arterial variations in the upper extremity.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/25. Internal mammary to pulmonary artery fistula presenting as early recurrent angina after coronary bypass.A 50-year-old man developed recurrent angina 1 year after coronary artery bypass surgery. The patient was found to have a large fistula involving branches of the internal mammary artery graft and the left pulmonary artery. In the absence of another clear cause for the patient's symptoms, we speculated that our patient's angina and abnormal stress nuclear study were due to coronary steal. In patients with a history of coronary bypass grafting, fistula formation between graft and native vessels should be considered as a possible cause of early recurrent angina.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/25. 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 = 1keywords = vessel (Clic here for more details about this article) |
6/25. Localized bronchiectasis is a definite association of coronaro-bronchial artery fistula.An 81-year-old smoker presented with acute coronary syndrome. coronary angiography revealed severe double-vessel disease, as well as the incidental finding of a coronaro-bronchial artery fistula that arose from the left circumflex artery. percutaneous coronary intervention was performed on the culprit lesion in the left anterior descending artery. A subsequent high-resolution computed tomography of the thorax revealed mild bronchiectic change in the corresponding area supplied by the coronaro-bronchial artery fistula. The patient had a normal lung function test and never had any chest symptoms. From the literature, the association of the coronaro-bronchial artery fistula and localized bronchiectasis is very definite, but the pathophysiology is still controversial.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/25. Case report: MRI evaluation of congenital coronary artery fistulae.Congenital coronary artery fistula is a rare disease and MRI is a promising technique that may be useful to demonstrate the coronary artery tree. We report three patients who underwent cardiac MRI to investigate right coronary artery fistulae. On clinical examination, a continuous murmur was heard along the left sternal border, and chest X-ray showed moderate cardiomegaly with enlargement of right chambers in all patients. Transthoracic Doppler echocardiography showed fistulae in two cases; the third case was not demonstrated by transthoracic or transoesophageal echocardiography. MRI demonstrated the course of the fistulous vessels in all patients. All patients underwent surgical closure of their coronary artery fistulae. MRI may show detailed anatomy of congenital coronary artery fistulae and may be useful as an additional non-invasive method in their investigation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/25. Coronary-pulmonary artery fistula arising distal to obstructive coronary lesions.We report 2 cases of coronary-pulmonary artery fistulae (CPF) arising distal to obstructive coronary artery disease. The fistula in the first patient was in the form of a tortuous dilatation of the distal portion of the right coronary artery and opened into the right pulmonary artery. In the second case, the fistula, a plexus of vessels, arose from the left anterior descending artery and entered the left pulmonary artery. Both the fistulae were successfully ligated at the time of concurrent coronary artery bypass graft surgery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/25. Nontraumatic chest wall systemic-to-pulmonary artery fistula.A congenital chest wall systemic-to-left pulmonary artery fistula fed by the left internal mammary and left gastric arteries in a 31-year-old man is reported. Attempted sclerosis was complicated by rupture of the communicating vessel, hemothorax, and deep vein thrombosis of the legs. fistula resection and pulmonary decortication were successfully performed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/25. Retinal angiomatous proliferation with a cilioretinal artery anastomosis: an unusual presentation.PURPOSE: To report an unusual phenotype of retinal angiomatous proliferation (RAP) in age-related macular degeneration (AMD) and its short-term response to laser photocoagulation. methods: Case report. RESULTS: An 85-year-old woman was found to have an unusual RAP with a major feeder vessel originating from a cilioretinal artery and associated with a cilioretinal-retinal anastomosis (C-RRA). Diffuse cystoid macular edema (CME), intraretinal hard exudates in a circinate pattern, and a fibrovascular pigment epithelial detachment (PED) were present. Laser photocoagulation was performed and led to occlusion of the cilioretinal feeder vessel and angiomatous lesion, with less CME. The other (retinal) arm of the C-RRA became more engorged and a new cilioretinal feeder developed, and both were associated with intraretinal hemorrhages. visual acuity was stable and the PED persisted throughout follow-up. CONCLUSIONS: We report an unusual phenotype of RAP that is associated with a major cilioretinal feeder vessel and comment on the possible effect of such an association on the response to laser treatment.- - - - - - - - - - ranking = 3keywords = vessel (Clic here for more details about this article) |
