RESUMO
Coronary angioscopy was performed in two patients with restenosis after excimer laser coronary angioplasty to improve our knowledge of restenosis after excimer laser angioplasty. The characteristics of the angioscopic findings in restenosis after excimer laser angioplasty consisted of smooth white plaques, which were distinctly different from the yellow plaques commonly observed in primary lesions. These findings indicate that restenosis in these patients after excimer laser angioplasty may be associated with smooth muscle cell proliferation and fibrosis.

We report two cases of coronary artery aneurysmal formation as long term consequences of Ho:YAG and excimer laser coronary angioplasty. This case report suggests that pulsed laser angioplasty may result in severe vessel wall damage that may lead ultimately to aneurysmal formation.

Pneumoperitoneum following cardiopulmonary resuscitation (CPR) results from a thoracic air leak (pneumothorax, pneumomediastinum) with escape of the air through diaphragmatic apertures (mostly foramen of Winslow) or primary perforation of the gastrointestinal tract (stomach or esophagus). We report three cases of pneumoperitoneum complicating CPR. As there was no clinical evidence of peritonitis, and the patients remained stable, a conservative approach was followed without surgical exploration. All patients recovered completely.
