Ascending aorta to supraceliac abdominal aorta bypass for coarctation of the aorta in an adult.

We present herein a case of ascending aorta to supraceliac abdominal aorta bypass for coarctation of the aorta in a 46-year-old woman with a history of hypertension. Because of severe calcification of the coarctation segment, we performed an ascending aorta to supraceliac abdominal aorta bypass instead of a conventional resection and anastomosis of the coarctation segment. Following surgery, the patient's blood pressure normalized, and she was discharged on the 14th postoperative day without any complications. An ascending aorta to supraceliac abdominal aorta bypass for coarctation of the aorta in adults is thus considered to be safe and easy to perform.

Bifurcated abdominal aorta, with a coarctation over the right branch of the bifurcated abdominal aorta and aberrant renal arteries originating from the left branch of the bifurcated abdominal aorta.

This study describes an unusual case of secondary hypertension in a young female patient presenting with severe hypertension and abdominal bruits. Gadolinium-enhanced MRA revealed a clearly bifurcated abdominal aorta, with a coarctation over the right branch of the bifurcated abdominal aorta and aberrant renal arteries originated from the left branch of the bifurcated abdominal aorta. Of interest is conventional angiography had failed to reveal these vascular abnormalities. This study mentions both embryologic and clinical aspects of this developmentally abnormal bifurcated abdominal aorta, coarctation of abdominal aorta and aberrant renal arteries.

Traumatic fracture of the abdominal aorta. Rupture of a calcified abdominal aorta with minimal trauma.

We report the case of an elderly man whose infrarenal abdominal aorta ruptured when the patient fell getting out of bed. Unique features of this case are the lack of aneurysmal disease, the insignificant nature of the trauma, and the severe, rigid atherosclerotic plaque in the infrarenal aorta. Pathologic examination of the resected aorta demonstrated the point of rupture to be at the junction of atherosclerotic plaque and normal aorta, suggesting that atherosclerosis is a predisposing factor in traumatic rupture of the abdominal aorta.

[Obstructive calcification of the descending thoracic aorta and suprarenal abdominal aorta. 2 cases].

Two cases of obstructive calcification of the aorta treated by surgery are reported. The disease is extremely rare, notably in the aortic segments involved in these two cases. Its clinical features were similar to those of coarctation. Intraluminal proliferative calcifications were present in the descending thoracic aorta of the first patient who underwent aortic resection with Dacron replacement prosthesis and in the suprarenal segment of the abdominal aorta of the second patient for whom an extra-anatomical bypass between the ascending aorta and the upper abdominal aorta was performed. The first patients remains with moderate arterial hypertension after 4 years; arterial pressure returned to normal in the second patient and is still normal after 15 months.

[Dissecting aneurysm of the abdominal aorta simulating acute abdominal diseases].

The paper is concerned with analysis of 9 case histories of patients with dissection and rupture of the abdominal aorta, simulating the acute abdomen. Diagnosis of this complication was very difficult: it was established in one patient only, in another patient it was suspected. In the other cases, a diagnosis was made at autopsy only. Physicians and surgeons of emergency care, outpatient clinics and hospitals should keep this pathology in mind.

Renal revascularization in patients with severe atherosclerosis of the abdominal aorta or a previous operation on the abdominal aorta.

Renal revascularization has been performed in six patients in whom severe atherosclerosis or previous operative procedures on the abdominal aorta precluded the performance of a standard aortorenal bypass graft. Splenorenal anastomoses were performed in three patients, superior mesenterorenal anastomosis in one patient, long saphenous vein iliorenal anastomosis in one patient, and renal autotransplantation in one patient. Successful renal revascularization with preservation of renal function was accomplished in all patients. The natural history of severe atherosclerotic renovascular disease has demonstrated the relatively frequent occurrence of arterial thrombosis and renal failure in patients with solitary kidneys. Occasionally, the presence of severe aortic disease precludes the use of standard aortorenal bypass grafting. Fortunately, as reported herein, alternate methods of revascularization are available whereby renovascular hypertension can be corrected and renal function preserved, with minimal operative risk.

Hazards of straight catheter aortography in the tortuous abdominal aorta.

Twenty abdominal aortograms utilizing a straight-tipped catheter were evaluated for catheter tip motion during the injection of contrast media. The catheter tips were stable in 15 patients but showed downward recoil in the remaining 5 patients. These 5 patients had marked tortuosity of their abdominal aortae which was felt to be the etiology of the catheter tip instability. Based on this finding, the use of a straight-tipped catheter is to be discouraged in patients with extreme tortuosity of the abdominal aorta.

[Aneurysms of the abdominal aorta in patients on a permanent hemodialysis program].

Surgical approach of an aneurysm at the infrarenal aorta abdominal, in six patients with terminal renal failure and chronic hemodialysis, is presented. They were all men, and the middle age was 62 years. There were two hospital deaths and a latter death. At the moment of this report, the three survival patients are well, after a follow-time of 34.6 months. Treatment of this group of patients, as well as the literature concerning to this subject are reviewed.

[Morphofunctional changes in the heart, liver and skeletal muscles during temporary occlusion of the abdominal aorta].

Experimental abdominal aorta ligation at the bifurcation site was performed in anesthetized mongrel dogs (body mass 12-17 kg) under controlled respiration. Aortic ligation produced a significant effect on the physiological indices of cardiac function, ultrastructure of the myocardium, liver and musculus quadriceps femoris, as well as on the content of macroergic compounds in these organs. One-hour aortic occlusion caused mainly reversible dystrophic changes in the tissues studied; 2-8-hour aortic ligation led to much more severe changes in the skeletal musculature, liver, and heart, while reperfusion, as a rule, impaired the cardiac and hepatic status. The latter may be attributed to the release of neuromediators and intermediate metabolism products from the ischemic skeletal muscles.

Extensive replacement of the aorta from the ascending aorta to the supraceliac abdominal aorta during a one-stage operation.

A successful replacement of the aorta from the ascending aorta to the supraceliac abdominal aorta in one operation is herein reported. The patient was 66-year-old woman who had DeBakey type I chronic aortic dissection with a pre-disseminated intravascular coagulation (DIC) condition. The image diagnosis revealed a markedly enlarged false lumen with a narrow true lumen in the ascending aorta extending to the diaphragm level while below the diaphragm level, the aortic dilatation was mild. The operation was performed through both a thoracoabdominal incision and a median sternotomy to expose the whole thoracic aorta, and the aorta was replaced from the ascending aorta to the supraceliac abdominal aorta. Selective cerebral perfusion was used for cerebral protection and this was a useful adjunct since no time limitations were thus required during repair of the aortic arch. Although the patient developed several complications postoperatively, she eventually recovered and was discharged from the hospital without any neurological disorders.

[Extra-anatomic bypass from the ascending aorta to the supraceliac abdominal aorta--surgical option applied to reoperation for aortic coarctation or interruption].

The optimal approach for reoperation following repair of aortic coarctation (CoA) or interruption (IAA) remains controversial. Four patients underwent extra-anatomic bypass for restenosis after repair of CoA or IAA. The age ranged from 4 to 12 years. The initial repairs for two CoA, one type A-IAA, and one type B-IAA consisted of two grafting, one subclavian arterial turning-down aortoplasty, and one subclavian flap aortoplasty. All of them underwent during infancy. Preoperative right arm systolic pressure ranged from 140 to 190 mmHg ar rest. Through a midline sternotomy and an upper laparotmy incision, an extra-anatomic bypass from the ascending aorta to the supraceliac abdominal aorta was employed using a 12 to 18 mm tube graft. All patients survived surgeries, and their hypertension markedly improved. Our experience confirms safety and effectiveness of this option in selected young patients with re-stenosis of following repair of CoA or IAA.

Hemophilia A, von Willebrand disease, and atherosclerosis of abdominal aorta and leg arteries: factor VIII and von Willebrand factor defects appear to protect abdominal aorta and leg arteries from atherosclerosis.

We hypothesized that patients with hemophilia or von Willebrand disease might be protected from atherosclerosis because of their coagulation defect. We studied 40 subjects affected by these two coagulation diseases using echocolor Doppler of the abdominal aorta and leg arteries, and compared the results with those obtained in 40 control patients who were homogenous with study patients in terms of sex, age, and risk factors for atherosclerosis. The probands presented a lower number of plaques than the 40 control subjects in the aorta and in the leg arteries. The most serious hemophilic patients had fewer plaques than controls or than patients with mild hemophilia. Both hemophilia and von Willebrand disease seem to protect against atherosclerosis.
