Anatomopathological classification of congenital vascular defects.

1. The proposed classification of congenital vascular defects based on anatomic and pathological features has proved to be useful in clinical practice. It is valid for vascular defects in all locations (central, visceral and peripheral), includes all types and anatomic forms of vascular malformations, yet is quite simplified. 2. A uniform and universal classification system is necessary for clear communication between the many different specialists dealing with congenital vascular defects. 3. It offers a clear and precise descriptive system to serve as the basis for diagnosis of congenital vascular defects. 4. A unified classification system offers the possibility of uniform analysis and comparative reporting between scientific investigators working in this field around the world.

Correction of lower limbs length discrepancy in congenital vascular-bone diseases by vascular surgery performed during childhood.

The progress in the treatment of congenital vascular-bone diseases in lower extremities caused by vascular malformations has been reviewed, along with an analysis of our clinical material and methods of treatment, and the results of our attempts to correct lower limb length discrepancy by early and direct vascular surgery directed at the cause of the bony changes. This experience leads us to the following conclusions: 1. Congenital vascular-bone diseases in lower extremities have a hemodynamic pathogenesis. The resulting bone changes can be caused by each of the different types of congenital vascular defects, or by a combination of them, with the resultant bone elongation or shortening due to hemodynamic and metabolic effects on the bone growth areas. 2. The recommended approach demands early, active, and causal treatment. 3. Operative techniques must be individualized and often seem unconventional because of the polymorphism of congenital vascular defects and specific differences in their anatomic and hemodynamic features. In severe cases, vascular surgery must be combined with other non-hemodynamic operations and nonsurgical methods (eg, orthopedic surgery, embolotherapy). 4. Early and active vascular surgery in childhood allows the correction of congenital lower limb length discrepancy, as judged by late follow-up evaluation.

Classification of congenital vascular defects.

Regardless of the existence of a large number of classifications, we consider that there are no grounds for ignoring the classical examples. On the basis of data to be found in literature, as well as from the analysis of 766 patients with vascular malformations which we studied in the course of 28 years and from the discussions during the 7th Meeting of the International Workshop on Vascular Malformations in Hamburg in 1988, we proposed a classification of congenital vascular defects according to their species and anatomopathological forms. The experience of practical and scientific collaboration with colleagues in six countries showed the practical value of this classification. It makes possible the formulation of a clear and precise clinicoanatomical diagnosis, facilitates the choice of surgical tactics and operative techniques and makes possible the scientific studies of the problem.

Haemodynamic pathogenesis of vascular-bone syndromes in congenital vascular defects.

This work is devoted to the haemodynamic pathogenesis of congenital vascular-bone syndromes. It is based on our studies of 209 patients suffering from angio-osteohypertrophic and angio-osteohypotrophic syndromes as regards the species and anatomopathological forms of the vascular defects, the haemodynamics, tissue metabolism and changes in the tubular bones. Establishing the haemodynamic pathogenesis of congenital vascular-bone syndromes in vascular defects is very important in determining the principles of their surgical treatment. It offers the possibility of a correct choice of operative tactics and techniques in these severe vascular diseases, which in many cases lead to disability and cardiovascular insufficiency.

Surgical treatment of congenital vascular defects.

The special nature of the anatomopathological structure and of the haemodynamic disturbances in congenital vascular defects causes certain peculiarities in their operative treatment. In our experience therapeutical strategy should be based on the following basic principles: active causal therapy combating pathogenesis, individual treatment, early operation, functionally radical operation, operation by stages and combined treatment. The numerous operative techniques are subdivided as follows according to surgical tactics: reconstructive operations, operations to remove the vascular defect, operations to reduce haemodynamic activity of the vascular defect and other nonhaemodynamic operations. Good postoperative results obtained after the use of the principles indicated above in a large number of patients treated by vascular surgeons in six different countries proved the validity of active and causal treatment of these severe diseases.
