Clinical-surgical sign for testing the sufficiency of the collateral circulation in operations for aneurysmas.

Description

Clinical-surgical sign for testing the sufficiency of the collateral circulation in operations for aneurysmas. It gives information about the circulation in the peripheral vessels following the  ligature of an extremity artery.

Coenen in 1913 first published the sign. Henle in 1914 pointed out that the sign had been demonstrated by him in 1912 (Verhandlungen des chirurgischen Kongresses, 1912; 1: 134) and by Lexer in 1913 (Verhandlungen des chirurgischen Kongresses, 1913; 1: 113). However, Lexer had merely used the sign as indicated by Henle on a patient. It would thus be more correct to term this Henle-Coenen sign.
