We present two cases of central venous catheterization (CVC) in which an ultrasound-guided in-plane approach was used. Case 1 was a 60-year-old man with acute myelogenous leukemia in whom a right supraclavicular CVC was performed. He had pancytopenia (leukocytes 2,000/μL; erythrocytes 350 × 10 4/μL; platelets 5.6 × 104/μL), and abnormal coagulability (prothrombin time-international normalized ratio 1.35). A linear array transducer was positioned cephalad to the right clavicle and rotated 30 clockwise. The 21-gauge needle was manipulated from outside of the transducer. A CV catheter (CV legaforce EX®; Terumo Co., Japan) was placed and stitched near the right clavicle. The patient felt no discomfort caused by the catheter. Case 2 was a 64-year-old women with malignant lymphoma whose right internal jugular vein was surrounded by abnormally enlarged lymph nodes. CVC was performed by the in-plane supraclavicular approach, avoiding puncture of the lymph node. This novel CVC technique is useful to minimize the risk of complications and patient discomfort by indwelling catheter.
