Using a new device to prevent pulmonary embolisms during pharmacomechanical thrombectomy

We have used a new device to prevent pulmonary embolism during pharmacomechanical thrombectomy in a 25-year-old postpartum woman. The Angel® catheter (BiO2 Medical Inc., Golden, CO, USA) is a temporary device that combines the functions of a vena cava filter (VCF) with those of a triple-lumen central venous catheter. Normally, a VCF is implanted to prevent pulmonary embolism during pharmacomechanical thrombectomy. However, the complications associated with VCFs increase with time, not all of the filter can always be retrieved, and there can be iatrogenic effects both during implantation and retrieval. In our experience, this new device is much simpler to deploy and to retrieve. As is shown in this case, this temporary device can be an interesting alternative to a VCF for preventing pulmonary embolisms during pharmacomechanical thrombectomy.

[Isolated ventricular diverticulum in asymptomatic male]

Ventricular diverticulum are small outpouchings, in the cardiac wall, which are mostly described as a part of malformation syndromes. This finding is infrequent in asymptomatic patients with no pathology in the thoraco abdominal line. The case we present shows a diverticulum in the cardiac apex in a male patient with no cardiological clinic manifestations and with an abnormal electrocardiogram. At present, magnetic resonance is the best diagnostic test, for this kind of malformation, and is also the most reliable in the follow-up of these patients.

Pulmonary tuberculosis presenting with cutaneous leukocytoclastic vasculitis

This case report deals with a rare association: tuberculosis and cutaneous leukocytoclastic vasculitis. The patient was a 36-year-old man with no significant past medical problems. He presented with a palpable purpura on both legs, low-grade fever, cough and expectoration, progressive dyspnea due to a massive left pleural effusion and a symmetric swelling on his ankles and wrists. Skin biopsy yielded a histological diagnosis of leukocytoclastic vasculitis and the primary diagnosis was only achieved after performing a pleural biopsy, which unequivocally showed the presence of Mycobacterium tuberculosis. This case shares many features with the few cases already reported in the medical literature. Possible pathogenic mechanisms are reviewed and discussed in detail.
