[Hemangioendothelioma of the right supra-clavicular region. Clinicopathologic study and management. Report of a case (author's transl)]. / Hémangioendothéliome du creux sus-claviculaire. Aspect diagnostique et thérapeutique. A propos d'une observation.

The authors present a case of hemangioendothelioma of the right supra-clavicular region in a 14-year-old boy. Interest of scanner in extension bilan and supraselective arteriography with tumor embolisation are stressed. Complete excision was possible and no sign of recurrence is noted 18 months later. Essential characteristics of a such tumor are reviewed.

[Per-operative blood flow measurement, complement to arteriography. Control and prognostic appreciation method (author's transl)]. / Débitmétrie per-opératoire, complément a l'artériographie. Méthode de contrôle et d'appréciation pronostique.

Per-operative blood flow measurement is studied as hemodynamic control in complement of arteriography (anatomic control). Early (1 month) and late (2 years) results are so reviewed in 217 popliteal or distal revascularisation. The authors attach more importance to the late value of peripheral arterial resistance with appears in relationship with early prognostic and post-operative failure. The authors recommend a vascodilative test to define maximum flow and real value of peripheral arterial resistance. The study of intra-arterial vasodilator response appreciates better the value of distal run-off receptivity and was found to correlate well with clinical results. The present study demonstrates prognostic significance of per-operative flow data.
