Double lumen picc placed in left upper arm brachial vein without difficulty on 3/15- tip at CA junction(pt. getting TPN,lipids,PCA, and IVF). On 3/21 left elbow became swollen,warm, red. US done- shows large volume clot in lower left jugular vein. No clot extends around the picc. Subclavian,axillary,brachial patent with good flow. MD's discontinued picc line on 3/21. Left elbow symptoms more severe, diagnosed as cellulitis and started on abx. Was all of this caused by the picc line? Thanks.
