BACKGROUND AND OBJECTIVES Excessive anticoagulation is a frequent complication of anticoagulant therapy. The risk of hemorrhage approximately doubles for each one point increase in the International Normalized Ratio (INR) above 3.0. Reducing a prolonged INR to within the desired therapeutic range requires that oral anticoagulants be withheld. In addition, vitamin K may be administered. Since th...

Symmetrical peripheral digital gangrene is a life-changing complication, caused by a pro-thrombotic life-threatening disease, such as disseminated intravascular coagulopathy (DIC) secondary to systemic infection. We describe the unusual case of a woman who developed symmetrical peripheral digital gangrene following DIC because of malaria. While initial treatment led to cure of the infection, in...

We report a fatality due to massive gastrointestinal haemorrhage in a patient receiving prophylactic dabigatran etexilate following a total hip replacement. A 79-year-old woman was commenced on dabigatran for venous thromboembolic prophylaxis following a total hip replacement. She presented again four days after surgery with haematemesis and hypotension but her coagulopathy could not be correct...

Spontaneous splenic rupture (SSR) in a patient undergoing hemodialysis has been described as an extremely rare and potentially fatal complication. We report here spontaneous splenic rupture in a 52-year-old woman undergoing regular hemodialysis for end-stage renal disease (ESRD). She complained of colicky abdominal pain in the left upper quadrant area and dizziness when she assumed an upright p...

We report a case of a 60 year-old woman with von Willebrand disease type I that was submitted to a mitral valve repair. The patient needed special care due coagulopathy and needed VIII factor (VIIIf) and von Willebrand factor (vWf), before, during and after surgery. There was no complication during or after surgery. Patient is asymptomatic nine months postoperatively. The correction of VIIIf an...

We describe a rare complication of myelography. A subarachnoid filling defect was apparent on the postmyelographic CT but not on conventional myelography. MR imaging performed later showed a spinal subarachnoid hematoma (SSAH), extending from L3 to L5. Lumbar puncture may rarely be a cause for SSAH and is more common in patients with coagulopathy. Significant back pain, paresis, radiculopathy, ...

Hemorrhage into the soft tissues of the airway represents a potentially life-threatening complication of long-term anticoagulation. We report the case of a chronically anticoagulated 37-year-old male who developed a spontaneous hematoma of the epiglottis secondary to a supra-therapeutic INR. Epiglottic hematoma should be considered in the differential of any anticoagulated patient presenting wi...

Envenomations by venomous lizards are rare. Monitor lizard bite-induced acute kidney injury (AKI) is a previously unreported complication in humans. A 55-year-old female was bitten on her right leg during farming activity by a monitor lizard (Varanus bengalensis). The patient experienced severe local pain and bleeding from the wound, coagulopathy, hemolysis, rhabdomyolysis, sepsis, and AKI. Pat...

The role of ascitic fluid collagen in the pathogenesis of the coagulopathy that follows peritoneovenous shunting was examined. Collagen was partially purified from ascitic fluid and infused into rabbits. All animals developed changes in their haemostatic profile consistent with intravascular coagulation. Aspirin therapy, for five days before the collagen infusion, prevented these changes. Seven...

Coagulopathy during intraoperative cell salvage in a patient with major obstetric haemorrhage Editor—Rudra and Basak are to be congratulated on their successful management of major obstetric haemorrhage in a patient with an atonic uterus. The latest CEMACH Report has highlighted atonic uterus as the commonest cause of fatal maternal haemorrhage. However, we would take issue with the suggestion ...
