[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.

[Simultaneous coronary and carotid surgeries].

Two patients with severe coronary artery disease and significant stenosis of the left internal carotid artery were operated upon. A combined or simultaneous operation was performed in both, carotid endarterectomy plus coronary artery bypass surgery was performed. The patients are symptoms-free after the operation and with evidence of satisfactory reconstruction in the carotid and coronary arteries. A review of the topic simultaneous revascularization of the carotids and coronary arteries in presented.

[Splenorenal arterial shunt in the surgical treatment of renovascular hypertension. Lumbo-retroperitoneal approach].

Experience with the arterial shunt spleno-renal technics, made by lumbotomy and retroperitoneal approach into a group of 31 patients is reported. The medium age of patients was 44 years. Twenty patients were men and 11 women. All of them presented severe vasculo-renal hypertension and 13 had signs of renal failure. All patients underwent an arterial shunt spleno-renal, recording a case of postoperative death (rate of hospitalary mortality 3.2%). The 30 survivor patients underwent a follow-up as external patients during a medium period of 57.3 months. Renal failure improved after surgical procedure in 12 cases between the 13 patients with such disorder. Arterial pressure returned to normal levels in 24 cases, improved in 5 cases and failed in 1 case. This latter patient was re-operated, underwent a renal autograft with successful results. Historical evolution of such surgical procedure, as well as its indications and advantages, are commented. A bibliographic review about the subject is made.

[Secondary aorto-duodenal fistula and aneurysm of the abdominal aorta].

A case report of a man 58 years old with a history of surgical treatment for an aortic-abdominal aneurysm by an aortobifemoral bifurcated vascular graft is presented. The patient was admitted on Urgencies with digestive hemorrhage and he was submitted to an emergent surgical procedure. Surgical findings were a secondary aortoduodenal fistula and an aortic abdominal aneurysm located between renal arteries and the bifurcated prosthesis. Duodenal fistula was then closed and aortic aneurysm removed, interposing an straight Dacron prosthesis. Fifteen days after procedure, patient was discharged and a suitable duodenal and aortic restauration was demonstrated by duodenal transit and angiography. Two months latter, patient is asymptomatic. Relevant details in regard to diagnosis and treatment of such relatively rare affection are commented.

[Bronchoalveolar lavage in patients surgically treated with extracorporeal surgery].

Nineteen selected patients were operated of coronary artery bypass surgery or aortic valvular replacement. In this cohort a bronchoalveolar lavage was performed before and after cardiopulmonary bypass. A rise in the polimorphonuclear neutrophils count was found in the post-bypass lavage group. The increase on secuestration of neutrophils by the lung could be a manifestation of lung injury due to the cardiopulmonary bypass. A review of this topic is presented.

Splenorenal arterial shunt in the treatment of renovascular hypertension. Approach by a lumbar-retroperitoneal incision.

In a period of 16 years, 29 consecutive patients were operated on for a splenorenal arterial shunt through a lumbotomy incision and a retroperitoneal approach. There were 18 males and 11 females with a medium age of 42 years. All cases had uncontrollable and severe hypertension for an average medium time of 48 months, 11 patients had variable degrees of renal insufficiency. The diagnosis was made utilizing standard methods including in all cases angiography of the abdominal aorta, celiac axis and renal arteries. One patient died after the operation due to intestinal infarction, the remaining have been followed for a medium time of 50 months. All patients improved or cured their renal insufficiency. The hypertension was cured in 23, improved in 4 and failed in 1, this latter patient was successfully autotransplanted. A precise exposition of the surgical technique is presented with comments about their advantages and indications. A review of the literature in surgical experience with the technique of splenorenal arterial anastomosis has been done.

[Accidental opening of a Greenfield filter at the right atrium].

A case of patient with an accidental aperture of a Greenfield filter through the right auricula during the surgical procedure performed in order to insert the mentioned filter is presented. This filter had to be removed under extracorporeal circulation, and it was immediately followed by the placement of a clip in the inferior vena cava. Complications associated to the Greenfield filter and adequate approach to this rare event are commented.

Dysfunction of a Duromedics valve in the tricuspid position. Case report.

Tricuspid dysfunction appeared in a 47 year-old woman fifteen months after multiple valvular surgery, including aortic and tricuspid valvular replacement with Duromedics valves. At reoperation one of the leaflets of the tricuspid prosthesis was blocked with overgrown tissue from the native tricuspid annulus. The prosthesis was replaced with another Duromedics valve and the patient is doing well nineteen months later. This case, is the first report of dysfunction of a Duromedics mechanical cardiac valve inserted in the tricuspid position.

[Ascending thoracic aorta-supraceliac abdominal aorta by-pass in a patient with coarctation and partial hypoplasia of the arch and aortic isthmus].

A twenty years old patient, with arterial hypertension at the right arm and absent pulse in both lower extremities was studied by angiography, and a coarctation of aortic arch with partial hypoplasia of aortic arch and aortic isthmus was found. Patient underwent to a surgical operation and, by anterior approach, an ascending thoracic aorta-supraceliac abdominal aorta by-pass was made. In the present case report, advantages, indications and experience with such by-pass modality are review.

[Extracorporeal circulation and respiratory distress syndrome in adults].

Adult Respiratory Distress Syndrome account in about 2% of open heart operated patients. Pathophysiologic and pathologic concepts are commented and the three stages of the syndrome are exposed. Cardiopulmonary bypass induces a secuestration of polimorphonuclear granulocytes into the pulmonary capillary membrane, and this cells in special situations, can produce pulmonary edema. The study, in early stages of the cardiac operations, of certain granulocyte-produced mediators could be a predictor of postoperative pulmonary distress syndrome.

[Myocardial infarction in a young woman with left atrial myxoma].

A 38 year old female patient without coronary risk factors suffered an acute myocardial infarction. Echocardiographic and cardiac catheterization was undertaken and a left atrial mass with normal coronary arteries was assessed. The tumor mass was successfully resected and pathological examination of the specimen disclosed a myxoma. Three months after the operation the patient is symptom-free and an echocardiogram taken at this time showed no evidence of tumor. A bibliographic review of the association cardiac myxoma and coronary artery occlusion or myocardial infarction is done.
