Successful resection of a tuberculous pseudoaneurysm of the descending thoracic aorta: case report and review of the literature.

An aneurysm of the descending thoracic aorta was found in a 55-year-old woman. She had hemoptysis, fever, and weight loss beginning 1 month before hospitalization. A miliary tuberculosis developed after angiography. The patient underwent surgical resection of the aneurysm, which proved to be tuberculous. The aortic wall was reconstructed with a Dacron patch. Antituberculosis pharmacotherapy, started before operation, was discontinued after 16 months of administration. The patient is doing well 19 months after operation. The English literature reports only 7 other cases of surgical treatment of tuberculous aneurysm of the thoracic aorta. According to previous reports, early surgical intervention, combined with preoperative and prolonged postoperative antituberculosis therapy and close postoperative follow-up, is mandatory in this group of patients.

Aneurysm of an aberrant right subclavian artery. Report of a surgically treated case.

A 53-year-old man was admitted for treatment of an aberrant right subclavian artery aneurysm that had been diagnosed 5 years earlier and had recently begun to enlarge. The aneurysm, which involved the right subclavian artery from its origin, measured 47 mm in diameter and about 10 cm in length. Because of the lesion's size and friability, a 2-stage operation was performed. In the 1st stage, the right subclavian and right vertebral arteries were revascularized with double bypass grafts via a right cervical approach. In the 2nd stage, the patient was repositioned and a left thoracotomy incision was made. With the aid of left-heart bypass, the aorta was cross-clamped proximal and distal to the lesion, and the aneurysmal orifice was closed with a Dacron patch. The patient was discharged from the hospital on the 17th postoperative day and remains asymptomatic 24 months later. We recommend the 2-stage technique for similar cases because it prevents limb ischemia and reduces the risk of hemorrhagic and embolic complications.

Usefulness of color Doppler in the diagnosis of ventricular septal rupture after myocardial infarction.

Ten consecutive patients with ventricular septal rupture complicating acute myocardial infarction were studied by means of Doppler echocardiography (including two-dimensional, conventional and color Doppler techniques) and bedside right heart catheterization using a Swan-Ganz catheter. One patient died before an operation could be performed. Seven critically ill patients underwent emergency cardiac surgery without preoperative cardiac catheterization, while in two patients it was also possible to undertake coronary angiography before surgery. Two-dimensional echocardiography diagnosed post-infarction ventricular septal rupture in 6 out of 10 patients. Color Doppler revealed the presence and the location of septal rupture in all 10 patients. The color Doppler diagnosis was confirmed either by surgery or necropsy. The estimates of pulmonary artery pressure, obtained by color Doppler-guided continuous wave Doppler beam, were very close to those measured by simultaneous right heart catheterization. In 3 patients, patch leakage occurred 3 days, 15 days and 1 year after the operation. Two-dimensional echocardiography revealed the patch leakage in only one of 3 patients while its location was visualized by color Doppler in all 3 patients. In one patient the color Doppler diagnosis was confirmed at necropsy. In the remaining 2 patients, a small left-to-right shunt was demonstrated by radionuclide studies. Color Doppler echocardiography is a highly sensitive and rapid technique in the diagnosis of postinfarction ventricular septal rupture. In critically ill patients it offers relevant information and may obviate the need for any invasive preoperate investigation.
