[Anticoagulation Therapy for Prevention of Acute Pulmonary Thromboembolism in Patients with Intracerebral Hemorrhage in Acute Phase].

Pulmonary thromboembolism(PTE)can be a lethal complication in patients with intracerebral hemorrhage(ICH), and the early detection of deep venous thrombosis(DVT)is important for prevention of PTE. Anticoagulation therapy is effective for prevention of PTE; however, in ICH patients, the safety of anticoagulants is not established because of concern about ICH expansion. We investigated the clinical data of patients who developed ICH and assessed risk factors for DVT and the safety of anticoagulation therapy. Our study included 250 patients between 2014 and 2016. We performed weekly screening of D-dimer and ultrasonography of lower limb veins was performed when levels gradually increased or reached 10 μg/mL. In patients with DVT, we started anticoagulation therapy after systolic blood pressures were controlled at ≤140 mmHg. DVT was detected in 35(14.0%)patients, and 29(11.6%)underwent anticoagulation therapy. A hemorrhagic complication was observed in 1 case as gastrointestinal bleeding. Expansion of ICH was not detected in any cases. Symptomatic PTE occurred in 1 case with DVT, just before initiation of anticoagulants. Univariate logistic regression analysis revealed hemorrhage volume ≥30 mL and modified Rankin Scale score ≥5 at discharge were associated with increased risk of DVT, with odds ratios of 2.69 and 2.51, respectively. Our study suggests that DVT tends to occur in patients with severe ICH and that periodic measurement of D-dimer is useful for early detection of DVT. Anticoagulation therapy can be safely started in ICH patients under strict control of blood pressure.
