Acute limb ischemia caused by incorrect deployment of a clip-based arterial closure device.

Failure of a vascular closure device most commonly results in a hemorrhage or pseudoaneurysm formation. In this paper a rare case of severe acute limb ischemia following incorrect deployment of a clip-based closure device (Starclose SE, Abbott Vascular) in a 31-year-old woman is presented. Symptoms of acute limb ischemia occurred at the start of the ambulation, 6 h after completion of the procedure.

Heparins in cancer-associated venous thrombosis.

A close causal relationship between cancer and venous thrombosis gives rise to questions about the effect of treatment modalities, in particular of the administered drugs, in patients with cancer-related venous thrombosis. An increased risk of chemotherapy-associated venous thromboembolism (VTE) has been well documented, while the effect of heparins used in VTE treatment on the disease course and prognosis in cancer patients has not been fully elucidated. This paper discusses the outcomes of the studies conducted so far investigating the role of heparins, in particular, low-molecular-weight heparins (LMWHs), in the prevention of thrombosis in cancer patients.
