Coital injury requiring internal iliac artery ligation.

Profuse bleeding after voluntary sexual intercourse is an uncommon reason for admission to the gynaecological wards. Out of 12 such patients admitted to the Ipoh Hospital over a three-year period, one patient had life-threatening upper vaginal injury after coitus. Blood replacement and conventional suturing failed to arrest the bleeding. Bilateral internal iliac artery ligation promptly arrested further haemorrhage. Vigorous intercourse increases intra-abdominal pressure in women causing tensing of the cul-de-sac, decreasing the elasticity of the posterior fornix, resulting in vaginal laceration. Bilateral internal iliac artery ligation produces a 'pelvic compartment hypotension' converting a high arterial flow system to that of a low one resembling venous flow. The useful role of this procedure to contain pelvic haemorrhage is discussed.
