Right top pulmonary veins associated with lung incomplete fissure and displaced bronchus: a retrospective study using multidetector computed tomography

Objective Anatomical features associated with the right top pulmonary vein (RTPV) remain unclear. This study aimed to reveal the incidence, form and associated pulmonary anatomical features of RTPVs.

Description
Summary:Objective Anatomical features associated with the right top pulmonary vein (RTPV) remain unclear. This study aimed to reveal the incidence, form and associated pulmonary anatomical features of RTPVs. Methods Thoracic computed tomography images taken from 4673 patients at our hospital between 2016 and 2018 were analyzed retrospectively for frequency, bifurcation pattern, inflow site, vascular diameter, and associated pulmonary anatomical features of RTPV. Results RTPVs were observed in 154 (3.3%) patients; the mean diameter was 3.7 mm. The bifurcation patterns of without (V 2 type) and with branches of the right superior segmental vein (V 2+6 type) were present in 50 and 104 patients, respectively. The inflow sites were the superior pulmonary vein (SPV group) and other sites (non-SPV group) in 86 and 68 patients, respectively. The incidence of incomplete fissure (ICF) in patients with and without RTPV was 44.2% and 7.9% ( p
