| 释义 | stenoses plural ofstenosisspecialized Examples of stenosesstenoses Recurrences of stenoses in previously dilated pathways, and new stenoses in previously unobstructed pathways, are commonly seen at follow-up. We performed intraoperative stenting of congenital pulmonary venous stenoses in two infants with initial clinical and hemodynamic improvement. The acute and intermediate-term efficacy of balloon dilation of these stenoses has not previously been studied in a large group of patients. In individual cases, nonetheless, localized stenoses appeared to be effectively dilated as evidenced by the angiographic findings after balloon angioplasty. Echocardiography showed left ventricular hypertrophy and no residual stenoses. It has been found to be particularly valuable in the detection and follow up of pulmonary arterial stenoses following the arterial switch operation. Similar sequels have been reported following attempted surgical relief of congenital stenoses. Surgical reconstruction of such stenoses, carries the same risk of (re)stenosis. All the segmental stenoses appeared within 7 years of the onset of the disease. This stent procedure may be applicable to small infants with branch pulmonary artery stenoses, obviating the need for early surgical or balloon angioplasty techniques. One patient has discrete stenoses of the left anterior descending coronary artery and is scheduled for angioplasty. Of the patients, 13 had no significant stenosis, while 25 had significant stenoses and, therefore, underwent balloon angioplasty. There were stenoses at the origin of the brachiocephalic artery. There was no gradient within the aorta, nor any discrete coronary arterial stenoses. Attempts at further balloon dilation of the distal stenoses on the left were unsuccessful.
