WebA Doppler waveform was considered pulsatile when it had a cyclic retrograde component. A right atrium pressure of more than 8 mm Hg was considered elevated. Results: We found a statistically significant correlation between the presence of these abnormal waveforms and elevated right atrium pressure. WebDec 12, 2024 · Some estimates suggest that PICCs are responsible for over one-third of all upper extremity DVTs [ 4 ], suggesting that the arm veins are perhaps the most thrombotic sites in which a central venous catheter can be placed [ 5 ]. Upper extremity venous thrombosis related to PICCs is reviewed here.
