The dataset of duplex ultrasound assessment of the internal mammary artery in women with unilateral mastectomy followed by radiotherapy for breast cancer.

Adjuvant radiotherapy for breast cancer may involve some incidental exposure of the ipsilateral internal mammary artery to ionizing radiation. However, the relevant evidence is limited and inconsistent. The dataset presented in this article contains the information used to assess the effects of accidental radiation exposure on the internal mammary artery in patients with unilateral total mastectomy followed radiotherapy for breast cancer. The study population consists of two groups: the irradiated group and the control group. The left and right internal mammary arteries were assessed through the second intercostal spaces using a computed sonography system (Vivid S6; GE, Tirat Carmel, Israel) equipped with a 5.5 - 11 MHz transducer. The recorded parameters were the diameter, time-averaged maximum velocity, and blood flow of the internal mammary artery. The dataset contains two files of data: a raw and an analyzed data. The raw data file contains the individual information of each participant, including demographic characteristics and the parameters of the internal mammary artery duplex ultrasound imaging. The analyzed data file was made up of R Markdown, a markup language of R. The results of data analysis were presented in the related research article which has been accepted for publication in the Annals of Vascular Surgery. The dataset presented in this article may be reused for further studies in which the internal mammary artery is considered as potential donor or recipient vessels for a vascular bypass or free flap anastomosis.
