Other factors that have been thought to make the basilic vein the superior choice for PICC lines are that it has the least number of valves, better hemodilution capabilities and has a shallower angle of insertion compared to other veins. Additionally, it has the straightest route to its destination, as it courses through the axillary vein, then through the subclavian, and finally, settles in the SVC. The right basilic vein is the vein of choice due to its larger size and superficial location. PICCs are placed through the basilic, brachial, cephalic, or medial cubital vein of the arm. They can be inserted centrally (centrally inserted venous catheter CICC) or peripherally (PICC). Anatomy and Physiologyīy definition, a central catheter is a venous access device that ultimately terminates in the superior vena cava (SVC) or right atrium (RA). They can be used for medium-term venous access, which is defined as anywhere between several weeks to 6 months. They are 50 cm to 60 cm long single, double or triple lumen catheters that are placed in a peripheral arm vein and terminate in the thorax. Peripherally inserted central catheters (PICCs) are a subset of central venous catheters. Venous access can be obtained through conventional peripheral intravenous (IV) lines, midline peripheral catheters, and central venous catheters (CVCs). It is especially vital for critically ill patients who often require frequent blood sampling, vasoactive medications, rapid fluid resuscitation, prolonged antibiotic administration and various other indications. The ability to obtain venous access in the inpatient and outpatient setting is one of the most fundamental, yet, crucial components for a large number of diagnostic and therapeutic interventions.
