thrombi

Removal of caval and right atrial thrombi and masses using the angiovac device: initial operative experience.

Intraoperatively, multiple calcified thrombi were seen adherent to the trabeculated portion of the right atrial wall (Figure 2).

Autopsy revealed the pulmonary emboli to be tumor emboli, not bland thrombi, a finding that helped to explain tPA failure (Figures 3-6).

We report a case of rapidly evolving, multichamber thrombi in a patient who was ultimately diagnosed with ATTRwt cardiac amyloidosis.

Mural thrombi within aortic aneurysms and ulcerated atherosclerotic plaques are the most frequent nonheart causes of embolization [1, 2].

APTT was measured twice a week and the values of around 40-80 seconds were maintained, but several thrombi appeared on the mechanical valve at 22 weeks of gestation.

Similar vena cava tumour thrombi, however, are found in less common retroperitoneal primary neoplasms such as Wilms' tumour and various adrenal, uterine, and urinary bladder tumours [2].

Nevertheless, tumor thrombi in the portal vein itself can rarely be detected in patients with gastric cancer [1].

Our case objectively highlights the rare occurrence of free floating right heart thrombi and their association with pulmonary embolism and also focuses on the options of management of such thrombi.

It was hypothesized that the main component in hyperacute thrombi might be oxyhemoglobin, instead of deoxyhemoglobin or hemosiderin, which made the clot invisible to the identification of negative susceptibility vessel sign (SVS).[58] On the contrary, it was found that the negative SVS remained invisible on follow-up SWI in all patients without recanalization, indicating that this sign may not be simply related to the component of oxyhemoglobin,[59] and other undetermined factors may also be involved.
