Retroperitoneal fibrosis, either idiopathic or associated with aortic inflammatory aneurysm, is a chronic fibrotic disease that causes progressive obstruction of ureters and vessels around the lower abdominal aorta. Treatment is often difficult (surgery) or hazardous (steroids). We report a case of a woman with retroperitoneal fibrosis associated with aortic inflammatory ...

A two-layer proximal aortic anastomosis for juxtarenal abdominal aortic aneurysm resulting in satisfactory "match" between Dacron graft and aorta is obtained. With this technique we are able to avoid additional suture and carotid bleeding from the suture line. Follow-up aortograms and computerized tomography of the aorta have shown complete exclusion ...

Two cases of near-fatal aortic abdominal aneurysm (AAA) are described which were successfully stabilized by a new principle for exerting abdominal compression, the non-pneumatic medical antishock trousers (NP-MAST). Obviously, the compression obtained with the NP-MAST suffices for this dramatic emergency. Moreover, compared with pneumatic antishock garments (PASG), the NP-MAST has ...

OBJECTIVE: The differentiation of supra-, juxta- and high infrarenal abdominal aortic aneurysms (AAA), which is essential for good surgical management, remains problematic. This prospective study assessed the value of highly overlapping vs. contiguous axial spiral computed tomography (CT) reconstructions in the pre-operative assessment of AAA. PATIENTS AND METHODS: Thirty-five patients ...

The relative importance of hereditary and mechanical factors in the pathogenesis of aneurysms remains as controversial today as it was two decades ago. The cases of two patients with unilateral paresis resulting from poliomyelitis who presented with abdominal aortic aneurysms are reported. In addition, each patient had iliofemoral aneurysms contralateral ...

Adaptation of new clinical products should be based upon thorough scientific evaluation of properties and performance in vitro and in vivo. Developmental animal research experimentation is classically carried out by the manufacturer with eventual government approval. However, objective data needs to be recorded during clinical trials including handling characteristics, bleeding, ...

We have purified and partially sequenced a protein from the adventitia of the human aorta (aortic aneurysm antigenic protein 40 kDa; AAAP-40) that has homologies to bovine aortic microfibril-associated glycoprotein (MAGP-36). It is immunoreactive with immunoglobulin G (IgGs) purified from the serum and aortic wall of patients with abdominal aortic ...

Infected aortic aneurysms are a rare (1.3% of all abdominal aortic aneurysms) but life-threatening disease. At present controversy continues about the specific diagnosis and the best surgical management. We present one case of infected aortic aneurysm treated with in situ reconstruction with cryopreserved arterial homograft. He was a 50-year-old man ...

We describe the regression of a 6.5 cm diameter abdominal aortic aneurysm in a 71-year-old patient within 1 year of aortic endograft placement. The aneurysm decreased in size to 4 cm at 3 months and was 3.3 cm at 8 months on duplex examination. By 1 year a spiral computed ...
Falk V - - 1997
Coronary artery disease and poor left ventricular function are the most important risk factors for morbidity and mortality in patients undergoing abdominal aortic aneurysm repair. Effective screening programmes and prior revascularization procedures (percutaneous translumincal coronary angiography and coronary artery bypass graft surgery) have helped to decrease the risk of cardiac-related ...
Schneider J R - - 1997
Repair of abdominal aortic aneurysms may require aortic occlusion above the renal arteries. Despite fears of renal, hepatic and intestinal ischemia, recent publications have suggested that when repair would be difficult or impossible with infrarenal aortic clamping, supraceliac clamping may not be associated with significantly increased morbidity. Between February 1985 ...

An eight-month-old male child presented with a nonpulsatile abdominal mass, which was detected during a routine follow-up examination. After ultrasound examination a tentative diagnosis of pseudoaneurysm of the abdominal aorta was made. An umbilical artery catheterisation had been performed for procuring arterial blood gases after birth for treatment of birth ...

Pulsatile blood flow using incompressible newtonian fluid is investigated numerically in abdominal aortic aneurysm models with the aid of transient Navier-Stokes equations for axisymmetric geometry. The arterial wall is assumed to be rigid. The actual arterial pressure-velocity pulse at the abdominal aorta is used as the inlet boundary condition to ...

BACKGROUND: Information on the anatomy of the abdominal arterial system in Insectivora is scarce. We described the origin, distribution, and variations of the visceral abdominal arteries in some Soricidae in order to provide the first comprehensive data on this subject in Insectivora. Results were interpreted from a functional and phylogenetic ...

In a 35-year-old multiparous patient, an ultrasound scan performed at 32 weeks' gestational age for size less than dates revealed an appropriately grown fetus with a two-vessel umbilical cord. Also noted were dilated, tortuous abdominal and pelvic vessels. A scan at 33.5 weeks confirmed the two-vessel cord and noted a ...

Coagulopathy associated with aortic operation is generally described in patients undergoing supraceliac aortic clamping or ruptured abdominal aortic aneurysm repair. This intraoperative complication is managed with component blood replacement and occasional use of aminocaproic acid. The presence of intraoperative coagulopathy associated with aortic reconstruction for occlusive disease is not described. ...

A pathologic feature commonly associated with abdominal aortic aneurysms is the presence of variably sized and shaped intraluminal thrombus, which may be fundamental to the disease process. However, the precise role of the intraluminal thrombus in the formation, enlargement, and rupture of abdominal aortic aneurysms is unknown. The hypothesis tested ...

Pseudo-aneurysms after abdominal aortic replacement are rare, occurring in less than 1% of operated patients. Usually asymptomatic, they may present clinically as a pulsatile mass or less commonly complicated with rupture. Aortocaval fistulas are rare, usually related to ruptured aortic aneurysms or trauma. A case of aortocaval fistula secondary to ...

A case of cholesterol embolisation (CE) following instrumentation of an aneurysmal aorta is presented. The patient developed myalgias, livedo reticularis in the buttocks, suprapubic area and legs, that progressed to patchy gangrene and renal failure. Maximum conservative management including heparin, iloprost and haemodialysis was ineffective, in keeping with previous reports ...

Seroepidemiologic studies have indicated an association between chronic Chlamydia pneumoniae infection and coronary heart disease. The organism, which is a common respiratory pathogen, has been demonstrated in atherosclerotic lesions of the aorta and coronary arteries. Abdominal aortic aneurysms are frequently associated with atherosclerosis, and inflammation may actually be an important ...
Compagnoni G - - 1997
A rare case of retroperitoneal sarcoma arising from an aneurysm sac is diagnosed in a patient following tube graft repair of the abdominal aortic aneurysm. The radiographic studies illustrate the characteristics of malignancy which are distinguishable from more common vascular complications. Malignancy should be considered in the differential diagnosis of ...
Carrillo E H - - 1997
As the population ages, abdominal aneurysms are expected to increase in frequency, as well as in the number of elderly patients involved in automobile trauma. Therefore, the number of incidental abdominal aortic aneurysms found in elderly trauma patients should be expected to rise. The purpose of this paper is to ...

Acute ischemic colitis is noted as a rare but lethal complication of abdominal aortic aneurysm (AAA) surgery. Because of its high mortality a reliable method of monitoring colonic blood perfusion to predict the possible occurrence of ischemic colitis is highly desirable for AAA surgery. We have tested the use of ...

Inflammatory abdominal aortic aneurysms (IAAA) occur infrequently in clinical practice. The reported incidence varies from 2.5-15% of all abdominal aortic aneurysms (AAA). Four percent of all AAA rupture into the vena cava. IAAA rupturing into the vena cava is exceedingly rare. To date, four such cases have been reported. IAAA ...
