1/94. Late in-stent restenosis of the abdominal aorta in a patient with Takayasu's arteritis and related pathology.This report describes an in-stent restenosis of the infrarenal aorta in a patient with Takayasu's arteritis in a nonactive state. A 10-mm-diameter Wallstent had been deployed 42 months previously. The stented restenosed segment was replaced by a surgical graft. Histopathological examination of the excised aortic segment showed a thin layer of fibrocellular neointima and massive organized and calcified thrombus. To our knowledge, this is the first histopathological report of a late in-stent restenosis of the abdominal aorta in Takayasu's arteritis.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
2/94. 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 = 1keywords = organ (Clic here for more details about this article) |
3/94. Unusual complications in an inflammatory abdominal aortic aneurysm.An unusual case of an inflammatory abdominal aortic aneurysm (IAAA) associated with coronary aneurysms and pathological fracture of the adjacent lumbar vertebrae. The associated coronary lesions in cases of IAAA are usually occlusions. In the present case, it was concluded that a possible cause of the coronary aneurysm was coronary arteritis and the etiology of the pathological fracture of the lumbar vertebrae was occlusion of the lumbar penetrating arteries due to vasculitis resulting in aseptic necrosis. Inflammatory AAA can be associated with aneurysms in addition to occlusive disease in systemic arteries. The preoperative evaluation of systemic arterial lesions and the function of systemic organs is essential.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
4/94. A subclavian artery aneurysm associated with aortitis syndrome.We performed surgery on a 61-year-old woman who had increasingly severe right shoulder pain and paresthesia in her right upper extremity as a result of a large right subclavian artery aneurysm. She had suffered from aortitis syndrome for 10 years for which she was treated with steroids and had multiple arterial lesions, including bilateral subclavian artery aneurysms, abdominal aortic aneurysm and obstruction of bilateral superficial femoral arteries. The right subclavian artery aneurysm measured 4 cm in diameter and rupture appeared imminent, prompting surgical therapy. Via the supraclavicular incision approach and additional partial sternotomy, the aneurysm was excluded and the brachiocephalic to right axillar arterial bypass was set up using an extended polytetrafluoroethylene graft. The patient recovered without complications and a subclavian artery aneurysm demonstrated by computed tomography was thrombosed 1 month after surgery. In conclusion, we recommend the exclusion technique to treat subclavian artery aneurysms in cases in which aneurysmectomy is likely to injure adjacent veins and nerves.- - - - - - - - - - ranking = 4.0587795210605keywords = nerve (Clic here for more details about this article) |
5/94. Chronic leg ulcers: types and treatment.Disorders of the arteries, veins, or nerves, alone or in combination, can result in leg ulcers. The presentation in these cases varies with the cause, which in turn guides management. A differential diagnosis is critical, because treatment that is essential for one type of ulcer may be contraindicated in another.- - - - - - - - - - ranking = 4.0587795210605keywords = nerve (Clic here for more details about this article) |
6/94. Bilateral glaucomatous optic neuropathy in Takayasu's disease without cervical arterial stenosis.PURPOSE: Although significant decrease in retinal perfusion is usually not observed before all of the cervical arteries became markedly narrowed in patients with Takayasu's disease (TD), we present bilateral glaucomatous optic neuropathy in a patient with TD without any cervical arterial stenosis. methods: Ophthalmoscopic examination disclosed glaucomatous optic neuropathy in both eyes with 7/10-cup/disc ratio in the right eye and 9/10 in the left eye. Left subclavian selective arteriographic examination demonstrated segmental high-grade stenosis, namely 90 percent stenosis in the mid portion of the left subclavian artery. Arteriography, digital subtraction angiography (DSA), magnetic resonance angiography (MRA) and color Doppler sonography revealed patent cervical, carotid interna, ophthalmic, retinal and posterior ciliary arteries. RESULTS: Patient was followed up for 48 months with frequent intervals and there was no deterioration of visual acuity, visual field and optic neuropathy without any antiglaucomatous treatment. CONCLUSIONS: Although it is a known fact that classical ophthalmic manifestations of the TD occur only when major cervical arteries are occluded, no occlusion was observed in this patient with bilateral optic atrophy. The optic nerve damage is caused by various factors, but these factors require much elucidation before the optic neuropathy can be understood.- - - - - - - - - - ranking = 4.0587795210605keywords = nerve (Clic here for more details about this article) |
7/94. Occlusion of the left common iliac artery and consecutive thromboembolism of the left popliteal artery following anterior lumbar interbody fusion.We report on a case of occlusion of the left common iliac artery due to arteriosclerosis and consecutive thrombotic occlusion of the left popliteal artery in a 52-year-old man following anterior retroperitoneal interbody fusion of L4--S1. Initial symptoms included leg pain and numbness of the lateral shank, which were thought to be a result of lumbar nerve root irritation from surgery. diagnosis was not made until 13 days after surgery, when motor deficits were observed. angiography showed occlusion of the left common iliac artery and thromboembolism of the left popliteal artery. After thromboendarterectomy of the common iliac artery and thrombectomy of the popliteal artery, motor deficits of the left foot were resolved whereas symptoms of pain and sensory deficits continued. spine surgeons should be aware of this rare complication in cases of postoperative leg pain or of neurologic deficits in the lower extremity after anterior lumbar interbody fusions.- - - - - - - - - - ranking = 4.0587795210605keywords = nerve (Clic here for more details about this article) |
8/94. Upside-down orbitopathy: unilateral orbital dependent-tissue oedema causing total visual loss.The case is reported of a 24-year-old man who was involved in a road traffic accident and became trapped upside down with the right side of his face being the most dependent part of his body. Marked hemifacial tissue oedema was associated with right acute compressive orbitopathy and vascular compromise. Acute dysfunction of al orbital nerves was found on examination. Such neuropathy is usually related to the consequences of direct trauma, fractures or haemorrhage; however, computed tomography scanning demonstrated no evidence of orbital fracture or haemorrhage. Immediate anterior surgical orbital decompression was performed in the emergency room in addition to high dose intravenous steroids. Dependent orbtal tissue oedema is proposed as a mechanism of compressive orbitopathy with consequent ischaemic damage to all orbital nerves, total visual loss and complete ophthalmoparesis. Good recovery of other orbital nerves has occurred and the globe has reperfused. Despite intervention, no visual function has returned.- - - - - - - - - - ranking = 12.176338563182keywords = nerve (Clic here for more details about this article) |

10/94. Surgical endarterectomy for suprarenal iliac artery stenosis in renal allograft recipient.Aortoiliac surgery performed in renal transplant recipients carries the risk of inducing a prolonged period of ischemia that can threaten organ survival. Recently, endovascular techniques have been increasingly applied but the rate of complications and recurrences remains significant. We report the case of a kidney heterotopic allotransplant recipient who presented with a history of new-onset arterial hypertension, right lower limb claudication, and allograft dysfunction related to a long, eccentric, and ulcerated plaque causing hemodynamic stenosis of suprarenal iliac artery that was successfully managed with surgical endarterectomy. Despite new advances in less invasive procedures such as transluminal angioplasty and stent implantation, surgical endarterectomy of suprarenal iliac artery may be safely performed in selected heterotopic kidney transplant recipients. It allows for complete removal of the plaque, with better long-term results, and does not preclude subsequent endovascular or surgical procedures; therefore it should be considered a therapeutic option in this clinical setting.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
