Letter Case Reports
Azygos vein thrombosis secondary to a peripherally inserted central catheter (PICC).
This case illustrates a rare complication of a peripherally inserted central catheter (PICC). PICCs are associated with a significantly increased risk of upper extremity deep vein thrombosis; however, there are currently no case reports of isolated thrombosis of the azygos vein secondary to a PICC. ⋯ With the well-documented increase in the use of PICCs for venous access we remind clinicians to consider this rare complication.

To investigate the role of wall shear stress in aspects of the formation of fibrin sheath and intimal thickening in a dog model. ⋯ After catheter placement, fibrin sheath formation partially covered the catheter. Meanwhile, focal areas of intimal thickening were also seen in the venous wall adjacent to the sites of high wall shear stress. These findings indicate an important role of wall shear stress profiles in fibrin sheath formation and intimal thickening.

The purpose of this study is to evaluate the complications of peripherally inserted central catheters (PICCs) in orthopedic patients with chronic bone orthopedic infection. ⋯ Even in orthopedic patients with chronic orthopedic bone infection, PICCs have a low rate of complication. The increasing lumen number of the PICC is a potential risk factor in our series.

The objective of this study was to determine through a systematic review of the literature and meta-analysis whether success rates, time to cannulation, and number of punctures required for peripheral venous access are improved with ultrasound guidance compared with traditional techniques in patients with difficult peripheral venous access. ⋯ In patients with difficult peripheral venous access, ultrasound guidance increased success rates of peripheral venous placement when compared with traditional techniques. However, ultrasound guidance had no effect on time to successful cannulation or number of punctures required for successful cannulation.
