Thrombosis-free surgical procedures in severe (Homozygote) factor XII deficiency: report of four additional cases and literature review.
The outcome of various surgical procedures carried out in patients with severe (homozygote) factor XII deficiency were investigated for the appearance of blood coagulation-related complications with particular emphasis on thrombotic complications. The surgical procedures were total mastectomy, tonsillectomy and adenoidectomy, placement of a hip prosthesis, and double hernia repair. None of the patients slowed any complication. Several other reported cases of surgical procedures carried out in several patients ware found in the literature. Bleeding or thrombotic complications were noted in none of these cases. The surgical procedures in some cases were minor such as adenoidectomy, tonsillectomy, or nasal polyp removal. However several major surgical procedures were carried out in some patients (cholecystectomy, gastrectomy, repair of atrial septal defect, coronary bypass). All patients remained asymptomatic. In some cases whole blood and/or plasma were used as requested by the caring surgeons. In a few patients, the plasma was given prophylactically because of the long partial thromboplastin time. Finally, three patients (two for cardiac surgery and one after hip replacement) received heparin prophylaxis as foreseen by accepted procedures without the undue sequels. These data supply further evidence that factor XII deficiency does not only show any bleeding tendency but also can withstand even major surgical procedures without thrombotic complications.
