[Use of the Doppler effect in pathology and vascular surgery of the lower extremities].

A clinical, arteriographic and hemodynamic comparative study, using the Doppler effect in 100 cases, suggests: -- that a study of the Doppler effect is a very useful method of diagnosis to determine the site of obstruction and the state of the blood vessels beyond the obstruction, even in the absence of adequate radiological images; -- following operation, it permits one to assess a case of thrombosis, even when the latter is not obvious clinically. It makes unnecessary post-operative arteriographic controls in tired or high-risk patients.

[Bridges through the obturator foramen and suprapubic bridges].

Bridging through the obturator foramen and suprapubic cross-bridging are among the types of atypical bridging most frequently used in vascular reconstructive surgery. Suprapubic bridging, as with axillofemoral bridging, makes revascularization possible when there are contra-indications to a transperitoneal approach to the aortic bifurcation. Bridging through the obturator foramen makes it possible to avoid the edge of the scrapa, particularly when there is suppuration. These types of bridging, which are often the only way of avoiding amputation or of taking a grave risk, give results that are quite acceptable if not comparable to those obtained by the standard techniques.

[Compartment syndrome].

Partition syndrome constitutes a nosological entity which amalgamates various disorders whose common feature is hyperpressure in a muscular cavity of the limbs; one such case is Volkmann's Syndrome, another is Anterior Tibial Syndrome. This hyperpressure is caused by extrinsic compression or an increase in volume of the contents of the cavity (block of the venous return, or hyperhaemia). It brings on muscular and nervous ischemia. Sometimes a retrocession of the symptoms can be hoped for, by a halt in the causal factor (effort, plaster too tight) mostly a fasciotomy has to be performed to open the cavity and avoid the vicious circles which this process triggers off and maintains.
