Disseminated intravascular coagulation after craniotomy.
ABSTRACT Disseminated intravascular coagulation (DIC) is reported in neurosurgical patients; however, the incidence of DIC after craniotomy procedures is unknown. Using a surgical database, we identified 3164 patients who underwent primary craniotomy at Mayo Clinic Rochester between January 1, 2000 and December 31, 2004. Potential cases of DIC in this population were identified using 3 search triggers, patients: (1) in whom the diagnosis of DIC was noted on their hospital discharge summary, (2) who received red blood cell-free blood products, or (3) in whom a blood fibrinogen or d-dimer concentration was assessed. Using criteria based on laboratory values, we estimated the incidence of DIC developing within 72 hours of primary craniotomy to be between 13 and 44 per 10,000 patients. Despite a low incidence of DIC, the associated mortality rate was 43% to 75%. Traumatic head injury was a significant risk factor for the development of DIC [odds ratio of trauma was in the range of 16 (95% confidence interval (CI)=5.3-49) to 29 (CI=4.0-204)]. Autologous salvaged blood was administered intraoperatively to 44 patients, and 1 of these developed DIC. Although this small sample of patients receiving salvaged blood requires caution in interpreting the results, the risk of DIC seemed to be greater with salvaged blood than without [odds ratio 24 (CI=2.5-237)]. In children, 2 of 3 patients who developed DIC had congenital malformations of the brain. Findings from this study suggest that DIC is rare after craniotomy, but is often associated with mortality.

ABSTRACT: Acquired factor XIII (FXIII) deficiency is a common disease and seldom causes bleeding. However, severe FXIII deficiency may result in life-threatening bleeding. Although the inhibitor against FXIII has recently been focused as the cause of haemorrhagic acquired FXIII deficiency, the pathophysiology of inhibitor-negative cases could also be involved. We report a case of an 85-year-old Japanese man with serious subdural haemorrhage showing a remarkable decreased level of FXIII activity. He also manifested complications of compensated disseminated intravascular coagulation (DIC) with chronic renal failure, abdominal aortic aneurysm (AAA) and right renal carcinoma. Despite the successful evacuation of the haemorrhage, acute subdural haemorrhage subsequently developed that necessitated further craniotomies. Plasma cross-mixing studies and dot blot assay revealed no inhibitors against FXIII. We speculated that the decreased FXIII activity could be mainly due to hyperconsumption by DIC and surgery. Because plasma-derived FXIII concentrates are available to stop bleeding, clinicians should be aware of severe acquired inhibitor-negative FXIII deficiency in cases of unexplained excessive bleeding.Blood coagulation & fibrinolysis: an international journal in haemostasis and thrombosis 03/2013; · 1.25 Impact Factor

ABSTRACT: Disseminated intravascular coagulation (DIC) as a complication of surgery for ventriculoperitoneal (VP) shunts is extremely rare, and only one case has been documented in the literature. The authors present the case of a 9-year-old girl with shunted hydrocephalus who presented with a 3-day history of headaches and vomiting. A head CT showed enlarged ventricles compared with baseline. An emergent VP shunt revision was performed, during which an obstructed proximal catheter was found. Immediately after extubation, the patient became apneic and progressed to cardiopulmonary arrest. A breathing tube was reinserted followed by resuscitation attempts that led to extracorporeal membrane oxygenation. Soon after reintubation, bloody drainage was noted in the endotracheal tube, and subsequent laboratory studies were consistent with DIC. The patient died on postoperative Day 1, and autopsy findings confirmed DIC. Note that DIC is a recognized complication of trauma, particularly with brain injury, but it is rare with neurosurgical procedures. Disseminated intravascular coagulation should be considered if excessive bleeding occurs after any brain insult.Journal of Neurosurgery Pediatrics 03/2010; 5(3):306-9. · 1.63 Impact Factor
