Directory of Open Access Journals Sweden. It is usually presented with ischemic complication and high risk of limb loss. For that reason, its elective treatment is indicated and currently carried through with satisfactory results using endovascular techniques. We describe our experience with the use of an ePTFE-covered nitinol self-expandable stent graft - Fluency Bard, Germany, reinforced internally with the nitinol self-expandable Zilver stent Cook, USA for the treatment of a popliteal artery aneurism.

El tratamiento endovascular no puede ser utilizado en todos los pacientes. Endovascular treatment of the abdominal aortic aneurysm is consider an alternative to open surgery for high risk patients. Its goal is to exclude the aneurysm from the circulation by using an endoprothesis introduced from a femoral approach. Patients must be strictly selected to avoid possible complications. The most frequent limitation is related to anatomic contraindications such as visceral arteries involved in the aneurysm.

Fenestrated endograft have been recently developed to allow endovascular treatment when anatomic features contraindicate classic endovascular procedures. Fenestrated endograft have holes that match with the origin of the visceral arteries maintaining its potency.

In this paper we report the endovascular treatment of an abdominal aortic aneurysm by using a fenestrated endoprothesis in a patient whose left renal artery is originated from the aneurysm.

Full Text Available We present the case of aorto-iliac aneurysm in a patient with chronic renal failure requiring dialysis who were treated with an endovascular stent graft and, later on, submitted to kidney transplantation. A year-old male with renal failure requiring dialysis presented with an asymptomatic abdominal aorto-iliac aneurysm measuring 5. After four months, he was successfully submitted to kidney transplantation dead donor, with anastomosis of the graft renal artery in the external iliac artery distal to the endoprosthesis.

The magnetic resonance imaging, carried out 30 days after the procedure, showed a good positioning of the endoprosthesis and adequate perfusion of the renal graft.

In the follow-up, the patient presented improvement of nitrogenous waste, good positioning of the endoprosthesis without migration or endoleak. The endovascular repair of aorto-iliac aneurysm in a patient with end-stage renal failure under hemodialysis treatment showed to be feasible, safe and efficient, as it did not prevent the success of the posterior kidney transplantation. Endovascular treatment of renal artery aneurysms has been described as an alternative to conventional surgery.

We report the case of a patient with complex renal artery aneurysm on the right kidney who had hard-to-control arterial hypertension.

Endovascular treatment was performed with the aneurysm neck remodeling technique Moret technique, or balloon-assisted coil embolization. The patient achieved blood pressure normalization after the procedure without recurrence of symptoms or need for antihypertensive drugs. It is performed a literature review of the pathology in question, possible complications and made reference to the various treatment options, with particular emphasis on the new endovascular techniques.

Behcet's disease, a systemic vasculitis of unknown etiology, may be the cause of aortic aneurysmal diseases in some patients.

We report our experience with two Behcet's disease patients who presented with aortic aneurysms and were submitted to endovascular therapy, and describe their respective follow-ups. Current pathophysiology, diagnosis, and treatment approaches were reviewed.

Our experience suggests that the endovascular approach, combined with adequate immunosuppressive treatment, is an excellent therapeutic option for some patients with Behcet's disease suffering from aneurysms. Migration of the endoprosthesis is defined as the misplacement of its initial fixation. To assess the migration, the position of the.

Thoracic aortic aneurysms are less common than abdominal aortic aneurysms and can be found in ascending aorta, aortic arch, descending aorta or in a combination of these segments. In thoracic aortic aneurysms there exists a structural wall weakness that leads to a progressive arterial dilation with eventual. Reporte de un caso. Five patients have been operated on of thoracoabdominal aortic aneurysms.

The mean age was 53 years range and three were women. All the patients were symptomatic, three of them had arteriosclerotic aneurysms, and the other two had dissecting aneurysms. Three patients had been operated on previously. The exposure of aneurysm was made through a thoracoabdominal incision, in four patients clamps were placed above and below the aneurysm and it was incised longitudinally. Bypass between left atrium and left femoral artery with hypothermia and circulatory arrest was used in the other patients, since the.

We describe the case of a year-old adolescent with Marfan syndrome and a history of three previous cardiovascular surgeries: aortic and mitral valve replacement at the age of 5 and aortic valve replacement and reconstruction of the thoracic aorta with a tube of bovine pericardium at the age of ten.

In the first surgical procedure the aortic valve was replaced by a mechanical valve, and mitral and tricuspid valvuloplasty was performed. In a second surgical procedure during the same hospitalization, endovascular exclusion of the asymptomatic descending aortic aneurysm was realized without complications. Before discharge, a type II endoleak was diagnosed and managed through clinical observation.

After a year of the procedure, clinical and tomographic controls are satisfactory. Endovascular treatment of renal artery aneurysmal disease has been increasingly accepted as an alternative to conventional surgery, especially in cases of renal artery bifurcation or complex intrarenal aneurysms. The authors report a case of endovascular treatment of a saccular aneurysm of the right renal artery bifurcation associated with poorly controlled renovascular hypertension. Selective catheterization of the renal artery was performed and microcoils were inserted into the aneurysmal sac.

The aneurysm was completely obliterated with total preservation of renal blood flow. Clinical evolution was satisfactory with significant reduction in anti-hypertensive drugs.

Control tomographic angiography, after eight months, confirmed treatment success. Esses fatores melhorando a qualidade de vida justificam a aneurismectomia.

Since the first reports about left ventricular aneurysmectomy, many features have been established, but there are controversies concerning the ideal technique of left ventricular. The popliteal artery aneurysm is the most frequent of the peripheral aneurysms. Although asymptomatic, it can complicate with severe limb ischemia due to embolization or thrombosis.

The surgical correction presents well-established techniques and results, while the less invasive endovascular therapy is still evolving. The recurrence is very rare and can be related to collateral artery refilling. We report a recurrent popliteal artery aneurysm after two years of conventional ligation and bypass surgery, in which an alternative endovascular strategy was successfully applied.

Factor XI deficiency, also known as hemophilia C, is a rare hereditary blood disease that manifests with persistent bleeding after surgery, trauma, menorrhagia, and dental extractions. The procedure was successfully performed with management of the coagulation disorder by preoperative and postoperative infusion of plasma and laboratory control of the coagulation. Angiographic and autopsy studies suggest that between 0.

We report our experience in the surgical treatment of intracranial aneurysms in a six year period, in Belo Horizonte, Minas Gerais, Brazil. We reviewed the hospital files, surgical and out-patient notes of all patients operated on for the treatment of intracranial aneurysms from January to January Four hundred and seventy-seven patients were submitted to craniotomies for treatment of intracranial aneurysms. The majority of patients were female Anterior circulation aneurysms were more common The most common location for the aneurysm was the middle cerebral artery bifurcation.

The patients were followed by a period from 1 month to 5 years. At discharge, Endovascular treatment of aortic pathologies is actually an alternative to open surgery. It has proven to be safe, showing similar or better results to those achieved by surgery. In this article, treatment of aortic pathologies by means of endoprosthesis is presented, as well as its indications, contraindications and future treatment with this kind of devices.

Modelos animais de aneurisma de aorta Animal models of aortic aneurysm. Este artigo tem por objetivo revisar os modelos de aneurisma arterial descritos atualmente. Experimental animal models have been used in vascular surgery for decades. The development of new interventional techniques in the endovascular treatment of aneurysms requires the creation of good experimental models to test these devices and study their impact on disease progression.

The aim of this article was to review arterial aneurysm models currently available. Several distinct models have been described but none of them satisfies all the requirements of an ideal aneurysm model.

Large animal models are appropriate for training, study of alterations in physiological parameters during and after device delivery, and integration. Todos apresentaram melhora desse sintoma. Isolated internal iliac artery aneurysms are rare. They affect 0. Patients are mostly asymptomatic, yet they can have abdominal pain, pulsatile mass in the hypogastrium or iliac fossa, or urinary, gastrointestinal or neurological compressive symptoms.

Such aneurysms are likely to course with an acute abdomen, especially when ruptured. Early diagnosis of isolated internal iliac artery aneurysms is difficult, as they are more easily detected when larger or ruptured, which significantly raises their morbidity and mortality rate and determines a poor prognosis.

Therefore, they are a therapeutic challenge. Surgical ligation has been the most common treatment; however, the endovascular approach has presented good outcomes, even in the event of ruptured aneurysms.

A case of ruptured isolated iliac artery aneurysm diagnosed during a laparotomy acute abdomen approach is reported. Among these, 47 procedures involved the aortic arch. The authors proposition is to make an experimental study of two methods of cerebral protection to be used during aortic arch aneurysm resection. The methods to be evaluated were profound systemic hypothermia under 20oC with great vessels occlusion and profound systemic hypothermia with selective right carotid artery perfusion.

Serial jugular vein samples for pH and PaC02 were analyzed to evaluate ischemic cerebral metabolic derangements. Hystopathological studies were also made at 45, 90 and We report the case of a 60 years-old woman with autosomal dominant polycystic kidney disease ADPKD that presented with headache and right complete ophthalmoplegia.

The CT scan raised the possibility of a giant aneurysm of the right intracavernous internal carotid artery, confirmed by angiography. The patient underwent endovascular occlusion of parent vessel with detachable coils, then she presented interruption of headache and partial recovery of ptosis and ophthalmoplegia.

We also discuss the natural history and compare the therapeutic options for the management of giant aneurysms of the cavernous portion of the carotid artery. Como se puede ver a partir. Aortic aneurysm AA is a pathology with high morbidity and mortality. The management can be expectant, surgical, or through endovascular repair EVAR. In Latin America the incidence of AA has increased and the analysis of therapeutic options, especially if they are expensive, is fundamental.
