Risk factors for unsuccessful removal of central venous access ports implanted in the forearm of adult oncologic patients.

Purpose: To evaluate the risk factors for unsuccessful removal of a central venous access port (CV port) implanted in the forearm of adult oncologic patients.

Materials And Methods: This study included 97 adult oncologic patients (51 males, 46 females; age range, 30-88 years; mean age, 63.7 years) in whom removal of a CV port implanted in the forearm was attempted at our hospital between January 2015 and May 2021.

Ultraselective transcatheter arterial embolization with small-sized microcoils for acute lower gastrointestinal bleeding.

Purpose: To evaluate the clinical outcome of ultraselective transcatheter arterial embolization (TAE) with small-sized microcoils for acute lower gastrointestinal bleeding (LGIB).

Materials And Methods: The subjects were 17 consecutive patients (mean age, 69 years) with LGIB who were treated with ultraselective TAE using small-sized microcoils between December 2013 and December 2019. Ultraselective TAE was defined as embolization of one or both of the long or short branches of the vasa recta.
