Although local arterial embolism is rather infrequent, it may occur during routine intramuscular syphilitic therapy. The after-effects of embolism are mostly mild, but they may sometimes include constitutional symptoms or interference with the patient's locomotion.
Cases of external popliteal paralysis,1 sciatica,2 gangrenous changes and destruction of the anastomoses of the gluteal and internal pudendal arteries, with destruction and gangrene of the rectum, bladder, genitals and thigh3 are reported.
