Abstract
Hemorrhagic complications remain a challenge with surgical procedures in patients with bleeding disorders. Tonsillectomy and adenoidectomy are some of the most common surgical procedures performed in pediatric patients. Adequate hemostasis in patients with bleeding disorders is centered on comprehensive hemostatic support and dexterous surgical technique. To assess our institutional experience with children and young adults with bleeding disorders that underwent tonsillectomy and/or adenoidectomy we performed a retrospective chart review of all such patients (age< 25 years) over duration of 20 years from July 1992 to July 2012. Nineteen patients were identified. The mean age was 10.2 years (Range 2.5 – 23.2 years) with 13 females and 6 males. The cohort included 2 patients with platelet disorders, 5 patients with von Willebrand disease and 12 patients with factor deficiencies (see table 1). Sixteen patients (84%) underwent tonsillectomy and adenoidectomy, while 3 patients (16%) underwent tonsillectomy only. Pre-operative treatment in the form of coagulation factor infusion (with a goal of 100% factor levels prior to surgery) or DDAVP was given to 16 patients (84%). Nine patients (47%) received anti-fibrinolytic agent, aminocaproic acid, starting pre-operatively for an average of 15.5 days (Range 10 – 36 days) post-operatively. Six patients (32%) received aminocaproic acid only post-operatively for an average of 12 days (Range 7-14 days). One patient received Tranexamic acid for 19 days. Intraoperative hemostasis was achieved by electrocautery in 16 patients (84%) and coblation technique in 2 patients (10%). Surgical hemostasis technique for 1 patient was undocumented, however this patient did not have any bleeding complications subsequently. Ten patients (53%) experienced post-operative hemorrhage including 2 patients (10%) with early (<24 hours) bleeding and 8 patients (42%) with delayed (>24 hours) bleeding from surgical site. Bleeding resolved spontaneously in 2 patients while 8 patients (42%) required interventions such as cauterization (4 patients), extended aminocaproic acid dosing (4 patients), DDAVP (1 patient), DDAVP and tranexamic acid (1 patient), recombinant factor VII (1 patient), Humate-P® (1 patient), Factor VIII infusion (1 patient) and Factor IX infusion (1 patient). Three patients (30% of bleeding patients) required transfusions including 1 patient that received platelet transfusions, 1 patient received PRBCs and another patient received FFP. Recurrent bleeding was noted in 3 patients and the rate was significantly higher in older patients amongst those with bleeding complications (p=0.0189).Table 1Age (years, months)GenderDiagnosisSeverity of diseasePost-operative bleeding (Early ≤ 24 hours, Delayed >24 hours)Recurrent bleeding14,5MEssential ThrombocythemiaModerateEarlyYes13,6MFactor VII deficiencyMildDelayedNo6,7FFactor VII deficiencyMildDelayedNo7,6FFactor VII deficiencyMildNo-11,2FFactor XI deficiencyMildEarlyNo8,4MHemophilia ASevereDelayedNo9,4FHemophilia A carrierMildDelayedNo15,2FHemophilia A carrierMildNo-5,0MHemophilia BMildNo-23,2MHemophilia BMildDelayedYes6,1FHemophilia B carrierMildNo-6,8FHemophilia B carrierMildNo-15,2FHemophilia B carrierMildNo-11,4FMay-Hegglin anomalyModerateDelayedNo4,0FType 1 von WillebrandMildDelayedNo13,5FType 2A von WillebrandModerateDelayedYes2,5MType 2A von WillebrandModerateNo-9,9FType 2B von WillebrandModerateNo9,1FType III von WillebrandSevereNo-
The rate of bleeding complications in pediatric patients with mild bleeding disorders undergoing adenotonsillectomy has been reported to be similar to that of normal population. In our cohort, delayed bleeding was more common than early bleeding consistent with current literature. We observed a higher rate of bleeding complications (53%) than reported in literature despite aggressive hemostatic support and adequate surgical techniques; however, our sample size was limited. Although there was no association between delayed hemorrhage and age, recurrent bleeding was associated with older age. We conclude that patients with bleeding disorders undergoing adenotonsillectomy are at a higher risk of bleeding and require close monitoring with hemostatic support for a prolonged period of time in post-operative period.
