1/124. Mediastinal irradiation: A risk factor for atherosclerosis of the internal thoracic arteries.Previous radiotherapy to the thorax is a risk factor for coronary artery disease. patients with radiation-induced atherosclerosis tend to be young and frequently have lesions involving the coronary ostia and left anterior descending artery. Bypass is often the most suitable method of revascularization, and given the young age of the patient, arterial conduits would be considered superior to vein grafts. However, the internal thoracic arteries can lie within the radiation field and may not be free of atherosclerosis. A 40-year-old man who required coronary artery bypass grafting for multivessel coronary artery disease 11 years following radiotherapy for Hodgkin's lymphoma is reported. Preoperative angiography showed that the right internal thoracic artery had significant atherosclerosis and was unsuitable as a conduit.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/124. Minimally invasive approach for aortic arch branch vessel reconstruction.Minimally invasive aortic arch branch vessel reconstruction was successfully accomplished in four patients over the past 3 years. There were no operative complications. Three patients had an uneventful hospital course, ranging from 3 to 5 days. The fourth patient with multiple medical problems and severe peripheral vascular disease had a prolonged hospital course for reasons unrelated to the surgical procedure. This minimally invasive surgical exposure can be used to effectively and safely repair innominate and left common carotid artery lesions.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
3/124. Acute mesenteric infarction caused by small vessel disease.A case of acute mesenteric infarction caused by small vessel disease is reported. The patient recovered after 2 operations by which extensive bowel-resections were performed. The resected bowel showed intimal hyperplasia and atherosclerosis of the small mesenteric arteries. Since also thrombocytosis and increased platelet aggregation was demonstrated the main cause of thrombosis however is supposed to be hypercoagulability.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
4/124. Endovascular treatment of noncarotid extracranial cerebrovascular disease.The last two decades have witnessed a growing application of endovascular techniques for the treatment of atherosclerotic disease of the extracranial vertebral arteries, subclavian arteries, and brachiocephalic artery. Beginning with simple balloon angioplasty, these minimally invasive techniques have now progressed to the use of stent-supported angioplasty. Stent-supported angioplasty is currently providing a therapeutic alternative to traditional methods of open surgery for revascularization of these vessels and increasing the therapeutic options available for patients who have failed maximal medical therapy. Additionally, endovascular techniques are also being used successfully to treat a variety of nonatherosclerotic diseases affecting the noncarotid extacranial arteries, such as inflammatory, radiation, and anastomotic-graft strictures; acute intimal dissection; traumatic and spontaneous arteriovenous fistulas; and aneurysms or pseudoaneurysms. Continued innovation and refinement of endovascular devices and techniques will inevitably improve technical success rates, reduce procedure-related complications, and broaden the endovascular therapeutic spectrum for extracranial cerebrovascular disease.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/124. Geriatric ureteropelvic junction obstruction: the possible role of an arteriosclerotic lower pole branch of renal artery: report of two cases.An 83-year-old woman presented with left flank pain and high grade fever. After left ureteral catheterization and intensive chemotherapy with hemoperfusion, surgical exploration revealed the lower pole branches of the renal vessels were obstructing the ureteropelvic junction (UPJ), and dissection of the vessels released the obstruction. An 82-year-old man presented with right flank pain. Angiography demonstrated UPJ obstruction caused by the lower pole branch of the renal artery. Arterial dissection with dismembered pyeloplasty resulted in improvement of obstruction. In both cases, the patients had a long history of hypertension with mild to severe arteriosclerosis. arteriosclerosis associated with fixation of the UPJ, may be one of the important factors leading to progressive hydronephrosis in geriatric patients.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
6/124. Ocular massage in a case of central retinal artery occlusion the successful treatment of a hitherto undescribed type of embolism.BACKGROUND: The pathogenesis of central retinal artery occlusions (CRAO) varies, depending upon the underlying disease. An embolic origin of an occlusion often occurs. PATIENT AND methods: A 50-year-old man with an occlusion of the left internal carotid artery was examined because of a left central retinal artery occlusion. fluorescein angiography revealed that in no blood vessel could any circulation of blood be demonstrated. The slight vascular filling with dye mainly came from collateral circulation at the disc. RESULTS: Ocular massage was carried out. After a delay of several minutes, the vessels of the fundus became increasingly filled with blood. The patient noticed continuing recovery in the vision of his left eye. During fluorescein angiography, carried out one day later, white embolic clots appeared in the arteries of the papilla, some of them moving with the velocity of the blood flow through the retinal vessels and reaching the periphery of the retina and immediately disappearing. Others moved more slowly. This was seen repeatedly over several minutes. CONCLUSIONS: In this patient we have recorded in a fluorescein angiogram bright boluses visible in the blood of the retinal arteries. We suggest that conglomerations of blood cells can also cause an obstruction of blood flow. The observation of this kind of bright clots (boluses) visible in the blood of the retinal arteries we did not find described in the literature. In such a situation ocular massage is extremely helpful. Therefore, ocular massage should be carried out in every patient with CRAO.- - - - - - - - - - ranking = 3.7332281544695keywords = vessel, blood vessel (Clic here for more details about this article) |
7/124. Dystrophic calcification of the radial artery.The radial artery continues to enjoy resurgence in popularity as a conduit for coronary artery bypass grafting but few studies have examined the prevalence of preexisting disease in this vessel. We highlight a potential, avoidable pitfall when use of the radial artery for coronary artery bypass grafting is proposed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/124. Atherosclerotic disruption of the aortic arch during coronary artery bypass operation.A 70-year-old-man presented with a symptomatic three vessel coronary artery disease and was scheduled for myocardial revascularization. During extracorporeal circulation an intrathoracal bleeding occurred and aortic rupture was suspected. An iatrogenic plaque rupture in the concavity of the aortic arch was found due to cannulation attempts. The aortic arch was grafted in the so-called elephant trunk technique. Thereafter bypass grafts were anastomosed to the stenosed coronary arteries. The patient was discharged from hospital after 2 weeks in good condition.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/124. Axillocoronary bypass in a patient with a severely atherosclerotic aorta.We report an axillocoronary bypass in a 70-year-old man with a severely atherosclerotic, calcified aorta. The patient had insulin-dependent diabetes mellitus and had 2-vessel coronary artery disease with a lesion in the left main coronary artery. He underwent an axillary artery-circumflex artery bypass with a saphenous vein graft combined with a bypass of the left internal thoracic artery to the left anterior descending artery without aortic cross-clamping. An easy, safe procedure, axillocoronary bypass is a viable option in coronary artery bypass grafting for patients with severely atherosclerotic, calcified aortas.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
