Exempel på stenoses

• 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.
