Paraplegia following balloon assistance after cardiac surgery.

Contrapulsation by means of an intra-aortic balloon is an effective and well-known therapeutic measure in the postoperative period after cardiac surgery, mainly when interrupting cardiopulmonary bypass in left ventricular failure situation (3, 4). We present the case of a patient who developed paraplegia 38 hours after surgery, which was attributed to contrapulsation.

Iatrogenic myocardial dysfunction after formalization of the heart.

A 20-year-old patient with myoepicardial echinococcosis was referred to our hospital for surgical treatment. After polycystectomy had been performed, the surgical area was mistakenly washed with formaldehyde solution, and severe myocardial dysfunction ensued. Histological alterations were compatible with toxic cellular damage.

[Vascular approach for periodic hemodialysis. Clinical course of 100 internal arteriovenous fistulas (author's transl)].

The clinical course of 100 internal arteriovenous fistulas in patients observed over a period of more than 6 months was analyzed. Ninety-six were practiced in the upper extremities as side-to-side anastomoses in the forearm between the radial artery and the nearest vein; three were constructed in the lower limbs as anastomoses between the femoral artery and the internal saphenous vein; and one was an autograft of the saphenous vein in the forearm. The most important complications observed were thrombosis (arising chiefly from scant venous development, surgical procedures, and episodes of arterial hypotension), distal ischemia, distal venous flow, infection of the fistula, and insufficient flow. A blood flow over 350 ml/min was achieved in all except two patients. The actuarial survival of individuals with arteriovenous fistulas is high at the present time, with 86 percent of the fistulas functioning after 3 years. The longest period of satisfactory arteriovenous fistula function is 8 years and 3 months.

Treatment of acquired chronic esophagopleural fistula by endoscopic cauterization.

Successful treatment of an eight-year-old esophagopleural fistula by means of endoscopic cauterization with an alkaline solution is reported. Previous therapeutic attempts with other more conventional measures had failed. The technique of the successful treatment is described. No complications could be attributed to its use.

Coarctation of the aorta and severe aortic insufficiency: What to repair first?

A new surgical approach is proposed for patients with coarctation of the aorta associated with severe aortic valvular insufficiency. The valvular lesion should be repaired first and the coarctation corrected during a second operation; both interventions should be done during the same hospital stay. We base our approach on the belief that improved coronary perfusion can be achieved when the aortic insufficiency is corrected first. The disadvantages of the opposite surgical approach, such as anticoagulation problems, renal underperfusion, and hypertensive complications are easily avoided.

Reoperation for dysfunction of the Björk-Shiley mitral disc prosthesis: report of eight cases.

Of 193 patients with Björk-Shiley mitral valve prostheses, replacement was necessary in 8 (4.1%). The reasons for reoperation were: detachment (4), thrombosis (1), technical error (1), and late disc entrapment (2). Five of these patients died (62.5%), the death being directly related to the need for urgent operation because of low cardiac output. We recommend avoiding the use of the larger sized Björk-Shiley prostheses, since striking of the disc against the ventricle wall, probably consequent to postoperative decrease in heart size, may appear even 1 year after implantation of the prosthesis. An early diagnosis and early reoperation offer these patients a much more favorable prognosis.

Cardiac valve replacement with the Björk-Shiley prosthesis in young patients.

Between 1971 and 1974, 26 valve replacements with the Björk-Shiley tilting disc valve prosthesis were performed in 23 children between 4 and 16 years of age. Mitral valve replacement was carried out in 11 patients, aortic valve replacement in 9 and double replacement in the other 3 patients. Several of the patients presented associated lesions which were also corrected at the same intervention, One patient died during the postoperative period; the remaining 22 all showed significant clinical remission. No incidents of thromboembolism or complications of any other nature were observed during follow-up periods of 6 to 26 months. It is our belief that the Björk-Shiley valve represents an improvement over other prostheses currently used for the surgical correction of valve disease in children.

Mustard procedure after Baffes operation.

Patients in whom Baffes' procedure has been done for palliative treatment of transposition of the great arteries may develop symptom recurrence later in life that deserves further treatment. A modified Mustard procedure is suitable for this purpose; the main difficulty in performing a formal Mustard operation is the proximity of the superior vena cava and of the inferior vena caval graft openings that enable the left pulmonary veins to drain without obstruction into the new atrium. This report deals with a 15-year-old patient in whom a modified Mustard technique was employed as a palliative method.
