Iatrogenic vascular lesions. Pathogenesis and treatment: an 18 year review.

The records of 304 patients operated on for vascular injuries were reviewed; 76 (25%) of these presented an iatrogenic vascular injury: 13 involved the upper limbs, 49 the lower limbs and 14 the neck and trunk. The lesions were due to a vascular catheterism in 40 patients, to orthopaedic treatment in 27 patients, to general surgery procedure in 3 patients, to urologic surgery in 3 and to otorhinolaryngologic surgery in 3. In vascular catheterism the prevalent complications were thromboses and embolisms; 3 patients needed an amputation after the surgical repair. In orthopaedic surgery, vascular complications were linked prevalently to hip surgery, exchange arthroplasty and upper tibial osteotomy. In urologic, otorhinolaryngologic and general surgery, vascular lesions were prevalently related to haemorrhagic complications, followed by incorrect haemostatic manoeuvres. Retroperitoneal fibrosis or previous surgery increased the risk of vascular injuries. Delay in treatment was responsible for post-operative death or incomplete recovery.
