ABSTRACT
Background: Iatrogenic vascular injuries are increasing and so severe that they can lead to prolonged hospitalization, high cost, loss of limb and even death of the patient with consequent lawsuit.
Objective: To review the incidence and pattern of iatrogenic vascular injuries, that have occurred during the last 32 years in several healthcare institutions of Mexico City.
Methods: It is a retrospective review of the records of 140 treated patients in five healthcare institutions from 1972 to 2004. There were 82 men and 58 women with age ranging from newborn to 82 years, with a mean age of 25 years. We recorded information on the original intervention, anatomic site of the injury, type of complication, outcome of the treatment and the incidence of lawsuits.
Results: There were 80 cases with arterial injury, 33 of venous ones and 27 injuries affecting both vessels. The injuries were located in the thorax of 11 patients, 30 in abdomen, 25 in upper limb, 69 in lower limb, and 19 had venous thromboembolic complications. The injuries happened as a surgical accident in 50 cases, during cardiac catheterization in 23, vein dissection in 15, arteriography in six and laparoscopy in five patients. There were 35 arterial thrombosis, seven arteriovenous fistulae, 5 pseudoaneurysms and 33 miscellaneous lesions. Microsurgical repair was successfully performed in five children with arterial thrombosis and post catheterization ischemia. Outcome: 99 patients (70%) recovered completely, 27 (19%) had amputations and 14 (10%) died. 18 patients (12%) brought lawsuits.
Conclusions: Every surgeon should keep in mind that an accident may occur at any time and aggravate the patient’s course. Hemorrhage, intimal tear, thromboembolism, pseudoaneurysms and arteriovenous fistulae were recorded in this review. Early recognition and correction of these injuries reduce the incidence and severity of the complications. Vascular access, minimally invasive surgery, orthopedic and general procedures were the main cause of severe iatrogenic lesions. The use of endovascular diagnostic and therapeutic procedures has motivated an increase in the number of iatrogenic injuries. Simple procedures such as sclerotherapy and vein stripping were not excluded. Particular attention must be paid to pediatric patients. Medical records must be complete if regarding any abnormal outcome; review by special committees must be done and iatrogenia analyzed to keep the staff informed and prevent the occurrence of similar injuries.
