Fine-needle aspiration (FNA) of the liver is a procedure considered virtually risk-free. We report here a patient with carcinoma of the pancreas, who suffered a fatal hemoperitoneum (HP) subsequent to FNA of the liver under the guidance of ultrasound. The patient had presented with migratory deep vein thrombosis (DVT), and recurrent cerebral embolism. The prothrombin time (PT) and partial thromboplastin time (PTT) had been normal, and FNA demonstrated adenocarcinoma cells. Autopsy findings demonstrated carcinoma in the tail of the pancreas with liver and adrenal metastases, massive HP, and findings of chronic disseminated intravascular clotting (DIC). Since chronic DIC with enhanced fibrinolysis might have participated in the fatal bleeding, we recommend that FNA should be contraindicated in patients suspected of having malignancy with migratory DVT and recurrent arterial embolism, despite normal PT and PTT tests, unless the appropriate laboratory tests succeed in excluding DIC.

Pancreatic carcinoma is associated with a high frequency of thrombosis. Most patients with thrombotic disease have a defective fibrinolytic defense system caused either by plasminogen activator deficiency, excess of plasminogen activator inhibitor (PAI-1), or a combination of the two. In the current series of 27 patients with pancreatic carcinoma, 17 had had deep vein thrombosis (DVT) since the onset of their malignant disease, and most were found to have high plasma concentrations of PAI-1 antigen and PAI-1 activity. Analysis of singleton samples from each patient yielded no correlation between previous DVT and currently high plasma PAI-1 concentrations. However, serial samples from 14 patients (8 of whom had histories of thrombosis) showed individual values varied sharply with time, with intermittent peaks both in PAI-1 antigen and PAI-1 activity for 11 of the 14 patients. Such variability may contribute to intermittently excessive hypercoagulability because of a relative reduction in fibrinolytic potential. These changes may predispose the patient to have thrombotic events in association with pancreatic carcinoma.
