Feb 26, 2006 · Cope needle demonstrates a diagnostic sensitivity equal to that of Abrams needle, without increase in the incidence of pneumothorax. Needle biopsy of the parietal pleura is useful in determining the cause of pleural effusion.

Cope needle biopsy was classically the first choice method for diagnostic search. Needle pleural methods for obtaining pleural tissue were been used since the second half of nineteenth century and with around 50% accuracy could be achieved, mainly for malignancy.

Aug 24, 2016 · Cope and Abrams biopsy needles are often used in “blind” biopsy procedures without the use of imaging guidance. In the United States, blind biopsy procedures have primarily been replaced by image-guided biopsies using semiautomated cutting biopsy needles.

Introduction of the Cope needle: With the stylet in place, introduce the outer cannula into the selected site. Use a rotary motion to advance the needle into the chest.

The advantage of the Abrams needle represented by the size of the material obtained and by the greater pleura proportion should be compared with the advan-tages of Cope needle: lower price, easy operation, possibility of being used in case of lack of pleural liquid, in other serosa or even in peripheral lung masses.

Percutaneous needle biopsy of the parietal pleura was first described in 1955 and has been a useful tool in the diagnosis of pleural TB. 62, 63 Specimens of parietal pleura can be obtained by means of a Cope needle, an Abrams needle, 64, 65 or …

The Abrams needle consists of three parts: an outer 11-gauge cannula (3 mm in outer diameter); an inner 13-gauge stylet that facilitates transparietal insertion; and a 13-gauge hooked needle for taking the biopsy.

Cope Needle. There are four parts to the Cope needle. The first part is the outer cannula . It has a cutting edge that facilitates the biopsy of the pleura. The outer cannula is hollow and creates an entry poi The two thinner pieces are used to create a stylet.

The object of this study was to compare the diagnostic yield of Abrams and Cope needles. Pleural biopsies were performed in 24 patients with both needles. In two patients, the procedure was repeated within a few days.

Feb 27, 2025 · Cope needles and Abrams needles, as shown in the images below, are most commonly used for blind or closed needle biopsy. This procedure generally is performed in the setting of a large...
