A classification of the island grafts.

The techniques for the use of island grafts in the closure of surgical wounds after the excision of cutaneous malignancies are quite simple and yield good cosmetic results. At present, the main configurations of island grafts are described with a diverse and confusing terminology. This article presents a logical classification of the island grafts based upon the shape of the primary defect, the shape of the partial closure, and whether the graft or grafts are distant or contiguous. By use of this classification, it is possible to develop a simplified approach to wound closure for almost all cutaneous surgical defects.

Echocardiographic assessment of right and left ventricular function after single-lung transplantation.

To evaluate the impact of single-lung transplantation on right and left ventricular performance and to identify potential preoperative characteristics that could predict postoperative outcome, a large group of patients were retrospectively evaluated by means of serial Doppler echocardiography. Twenty-six of 57 consecutive single-lung transplant patients had satisfactory Doppler echocardiographic studies before and after surgery. A significant reduction in right ventricular diastolic and systolic areas and an increase in right ventricular fractional area were noted after transplantation. The left ventricular contractility remained unchanged. In addition, significant reduction in right atrial area, right ventricular free wall thickness, and tricuspid regurgitation were also seen. Paradoxical septal motion present in eight patients before the procedure resolved in all of them after single-lung transplantation. Transthoracic echocardiography is a useful technique to document improvement in right ventricular function in 63% of patients following single-lung transplantation. Preoperative paradoxical septal motion identifies single-lung transplant recipients who have the largest postoperative right ventricular area reduction and fractional area increase. Alternative imaging modalities should be sought for single-lung transplant candidates in whom conventional transthoracic echocardiography is suboptimal.
