A 53 year old female who was maintained on long-term warfarin therapy due to history of pulmonary embolism, repeatedly presents with an abnormally prolonged Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT). After many asymptomatic episodes were corrected with Vitamin K therapy to temporarily reverse the effects of the warfarin, the cause of the apparent coagulopathy was further investigated. Factor Activity Assays of the common pathway factors II, IX, and X all revealed critically low values; below the threshold even a loading dose of warfarin is typically capable of eliciting. The patient tested strongly positive for Tissue Transglutaminase IgA, which is highly suggestive of a gluten-sensitive enteropathy. One effect of this condition is malabsorption due to flattened intestinal villi. The patient was determined to have an acquired vitamin K deficiency secondary to gluten-sensitive enteropathy. Her condition was exacerbated by the long-term warfarin therapy, resulting in the prolonged PT and PTT. The patient was treated with vitamin K therapy, which reversed the deficiency and corrected her abnormal coagulation results.

The aim of this study was to evaluate the correlation of clinical characteristics with serial imaging findings of symptomatic spontaneous celiac artery dissection treated by conservative management.. Eight consecutive, hemodynamically stable patients with symptomatic spontaneous celiac artery dissection without associated aortic dissection that received non-operative treatments were included in this study. Their clinical characteristics, treatment methods, serial imaging findings and outcomes were analyzed retrospectively.. Acute left flank pain related to splenic infarction was the most common clinical manifestation. Initial contrast-enhanced dynamic computed tomography scan showed celiac artery dissection with partial thrombosis in all eight patients and involvement of branch vessels in 7. Full anticoagulation was carried out immediately after the diagnosis in seven patients. All patients, except one with endovascular stent placement, were asymptomatic after successful conservative management and follow-up computed tomography scan showed preservation of distal perfusion with ongoing regression of false lumen in five patients. After a mean follow-up of 16 months, there was no mortality or morbidity related to the dissection.. Serial imaging findings showed that conservative management of celiac artery dissection can be performed successfully in selective patients with stable hemodynamics.
