2/344. embolism in a single functioning kidney: report of two cases.2 cases of embolism in single functioning kidneys are reported. In the first case there was an occlusion of the main trunk of the renal artery; the patient was treated by embolectomy. In the second case the occlusion of a major arterial branch was demonstrated; because of the bad general conditions the patient was treated with medical therapy. The authors review the literature and the indications for embolectomy in embolism in a solitary kidney.- - - - - - - - - - ranking = 0.2keywords = artery (Clic here for more details about this article) |
3/344. Fatal late multiple emboli after endovascular treatment of abdominal aortic aneurysm. Case report.BACKGROUND: The short term experience of endovascular treatment of abdominal aortic aneurysms (AAA) seems promising but long term randomised data are lacking. Consequently, cases treated by endovascular procedures need to be closely followed for potential risks and benefits. CASE REPORT: A 70 year-old mildly hypertensive male without previous or present arteriosclerotic, pulmonary, or urological manifestations was subjected to endovascular treatment after his mass-screening diagnosed abdominal aortic aneurysm had expanded to above 5 cm in diameter, the aneurysm having been found by CT-scanning and arteriography to be endovascularly treatable. A Vanguard bifurcated aortic stent graft was implanted under epidural/spinal anaesthesia and covered by cephalosporine and heparin (8000 IE) protection. Apart from treatment of a groin haematoma and stenosis of the left superficial femoral artery, the postoperative period presented no problems. A few days before the monthly follow-up visit, the patient developed uraemia, gangrene of one foot and dyspnoea. blood glucose and LDH was elevated. Deterioration led to death a month and a half after stent implantation. autopsy showed extraordinary large, extensive soft, brown vegetations in the lower part of the thoracic aorta above the properly infrarenally-placed stent. Microscopic examination revealed multiple microemboli in the liver, spleen, pancreas, intestines, testes, and especially the kidneys. DISCUSSION: Early death from microemboli after aortic stent implantation has been reported. However, the present case developed fatal multiple microemboli so late that they could not have originated from the excluded mural thrombus. The sudden death of an otherwise healthy man of extensive microemboli is difficult to explain. The stent application may have altered the proximal flow and wall movements disposing to microemboli in the case of vegetations.- - - - - - - - - - ranking = 0.2keywords = artery (Clic here for more details about this article) |
4/344. Diagnostic and surgical approach of innominate artery saddle embolus.patients with an acute arterial occlusion of the right upper extremity and absent axillary pulse should have a Doppler scan examination before a balloon catheter embolectomy is performed. If there is no arterial pulse detectable, an angiography should be performed afterwards to localize the embolus. In the case of a proximal arterial occlusion of the right arm, the authors recommend this procedure to prevent an embolus dislocation by catheter embolectomy and subsequent cerebral embolization. For direct surgical embolectomy the authors recommend a supraclavicular incision.- - - - - - - - - - ranking = 0.8keywords = artery (Clic here for more details about this article) |
5/344. Ultrastructural changes in a case of mucoid degeneration of the brachial artery.An electron microscopic (EM) description of mucoid degeneration of the brachial artery in a 67 year old man is presented. In this case, the affected artery showed mucoid degeneration of the intima and media circumferentially, dissecting and destroying the muscle fibres. Ultrastructurally, mucoid degenerating muscle cells showed numerous large mucin-containing vesicles in the cytoplasm. Cells were widely separated by large accumulation of mucoid material, which appeared to penetrate the extracellular collagen fibre bundles. Most of the nuclei of the smooth muscle cells displayed typical necrotic changes undergoing dissolution or having already broken up into discrete fragments. This case of intimo-medial degeneration (IMMD) suggests that the condition could arise spontaneously anywhere in the inner coats of the arterial system away from the vessels that are close to synovial joints. This is a rare presentation of IMMD of arteries, which has been described mainly in the aorta and its major branches.- - - - - - - - - - ranking = 1.2keywords = artery (Clic here for more details about this article) |
6/344. hyperhomocysteinemia, aortic thrombus, and peripheral arterial emboli--a case report.A young Native American woman presented with ischemia of the left lower limb resulting from embolic occlusion of the left common iliac artery and left femoral artery. The source of her emboli was aortic thrombus. The only underlying abnormality responsible for her hypercoagulability appeared to be hyperhomocysteinemia.- - - - - - - - - - ranking = 0.4keywords = artery (Clic here for more details about this article) |
7/344. Transient ischaemic attacks related to carotid stenosis precipitated by straining, bending, and sneezing.Three patients are described in whom one or more carotid territory transient ischaemic attacks (TIAs) were preceded by sneezing, straining, or bending over. It is argued that the mechanism involved dislodgment of embolic material from the site of carotid atheroma. This mechanism should be considered as an alternative to paradoxical embolism when TIAs are precipitated by such physiological manoeuvres. Furthermore, TIAs should be added to the list of medical hazards associated with such events.- - - - - - - - - - ranking = 1.5493580439086keywords = carotid (Clic here for more details about this article) |
8/344. Sequential retroperitoneal venous hemorrhage and embolism of an angio-seal puncture closure device complicating iliac artery angioplasty.PURPOSE: To present a case of iatrogenic puncture closure device embolization complicating surgery for retroperitoneal hemorrhage (RPH) secondary to angioplasty-induced common iliac vein trauma. methods AND RESULTS: A 78-year-old woman with rest pain underwent successful kissing balloon dilation of her aortoiliac bifurcation for a calcified ostial stenosis of the left common iliac artery. Hemostatic puncture closure devices (Angio-Seal) were used to secure both femoral punctures. A right-sided retroperitoneal hematoma developed, and during surgical exploration of the right groin, the Angio-Seal device was removed. The only bleeding site found was the external iliac artery puncture and it was repaired. She again became hypovolemic 18 hours later and was returned to surgery, where bilateral groin explorations and laparotomy by the vascular surgical team found a tear in the left common iliac vein. After repair, the patient was stable for 48 hours when the left leg became critically ischemic. angiography detected a new high-grade stenosis in the left profunda femoris artery; embolectomy retrieved a footplate from the left puncture closure device. The patient died 11 days later from multiorgan failure. CONCLUSIONS: RPH should be considered early as an occult cause of hypovolemic shock developing soon after even technically straightforward iliac angioplasty. Interventionists should be aware that using the Angio-Seal device risks acute limb ischemia if footplate embolization occurs.- - - - - - - - - - ranking = 1.4keywords = artery (Clic here for more details about this article) |

10/344. Monitoring of the extracranial and intracranial course of single emboli of cardiac origin: a preliminary report.Simultaneous monitoring of emboli in extracranial and intracranial arteries recorded with identical probes, in a patient with an artificial cardiac valve, allowed the identification and characterization of pairs of signals, which most likely represent single emboli flowing through the common carotid artery into the middle cerebral artery. This technique offers new insight into emboligenesis with obvious therapeutic implications.- - - - - - - - - - ranking = 0.83201364538516keywords = carotid, artery, carotid artery (Clic here for more details about this article) |
