INTRODUCTION Thoracoscopic lobectomy for congenital pulmonary airway malformation has been indicated from the neonatal period to adolescence. However, it is difficult to approach the pulmonary artery for lobectomy in congenital lung malformations with incomplete or absent interlobar fissures. Multidetector computed tomographic images and computed tomography pulmonary angiography gave us helpful...

Background: The fissures in lung enhance uniform expansion. These fissures may be complete, incomplete or absent. A detailed knowledge of variations of classical and accessory fissures is necessary for proper radiological interpretation. It is a guide to cardiothoracic surgeons performing segmental lung resections, lobectomies to have an uncomplicated perioperative outcome. So, the cadaveric st...

In this series a pictorial quiz pertaining to identification of normal anatomical structures and landmarks at a given level on the computed tomography (CT) is presented. An image depicting normal anatomy is followed by a series of images showing different pathologies. Readers are expected to identify and appreciate variation and changes in the normal anatomy in presence of a given pathology. Th...

Pulmonary fissures are important landmarks for automated recognition of lung anatomy and need to be detected as a pre-processing step. We propose a derivative of stick (DoS) filter for pulmonary fissures detection in thoracic CT scans by considering their thin curvilinear shape across multiple transverse planes. Based on a stick decomposition of a local rectangular neighborhood, a nonlinear der...

OBJECTIVE To evaluate two different approaches used to perform fused fissures in lobectomies in terms of persistent air leak (PAL) and their impact on length of hospital stay. METHODS One hundred and nineteen patients underwent lobectomy or bilobectomy in our unit. We focused on patients with fused fissures (63 patients), all of whom were selected intraoperatively based on predefined criteria...

BACKGROUND Treatment with lung volume reduction coils (LVRC) may be effective in patients with severe heterogeneous emphysema and incomplete fissures. OBJECTIVE We hypothesized that LVRC placement improves pulmonary function, exercise tolerance and quality of life in these patients. METHODS Twenty-six patients with chronic obstructive pulmonary disease (COPD), 13 males and 13 females, aged ...

We describe a new approach to detect the ssures between the lobes of the lungs in computed tomography (CT) scans. We focus on the detection of the major ssures in diagnostic CT. Our approach is to rst nd a region containing the ssure and then extract the ssure within this region by analyzing local features. We developed a \marching-bar method" to segment the region containing the ssure. After t...
