The Atraumatic Amniocentesis needle is manufactured by TSK Laboratory, Japan (Tochigi-Shi, Tochigi-Keri, 328 Japan). It is a 22 gauge, 90 mm needle. It has a pencil point tip with two circular holes at the tip. It is composed of a stainless steel AISI 304 with a polycarbonate hub. OD – 0.70±0.01 mm. ID – 0.40±0. 01 mm. Obturator length – 109.5±2 mm. OD of the obturator – 0.35±0.01 mm. Location ...
Abitract: Retrieval of a Thrombus Attached to a Cournand Needle • Upon completion of a carotid angiogram, a clot of platelets, leukocytes, erythrocytes and fibrin was found attached to a No. 18 gauge Cournand needle. The chance retrieval of this thrombus establishes the occurrence of thrombus formation on angiographic needles. Such thrombi could be the source of some post-angiographic infarctio...
PURPOSE To quantify needle placement accuracy of magnetic resonance image (MRI)-guided core needle biopsy of the prostate. MATERIALS AND METHODS A total of 10 biopsies were performed with 18-gauge (G) core biopsy needle via a percutaneous transperineal approach. Needle placement error was assessed by comparing the coordinates of preplanned targets with the needle tip measured from the intrapr...
S12 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 diagnostic value of specimens obtained with the new 20-gauge ProCore biopsy needle. Follow-up data are required to confirm the diagnostic accuracy of this agreement. DOI: 10.4103/2303-9027.212302
background: the purpose of this study was to evaluate the results of stereotactic breast core needle biopsy in a tertiary breast center of tehran university of medical sciences. methods: patients who were candidates for mammography-guided stereotactic breast core biopsy from march 2011 to december 2013 were included in this study. stereotactic biopsy was performed by a dedicated prone hologic m...
SUMMARY Sometimes, after local anesthetic injection for surgical procedures of the upper eyelid, it is possible to observe superficial preseptal hematomas or excessive lid swelling that may distort the tissues and obscure surgical landmarks. We present a technique to perform local anesthesia of the upper eyelids, using a 27-gauge needle and a 26-gauge filling cannula, that may decrease the inci...
Postmyelography headaches are produced mostly by CSF leakage at the dural puncture site and are therefore largely dependent on the size of the needle used. Our study of 300 consecutive outpatients who had lumbar myelograms performed with 25- and 26-gauge spinal needles shows that the procedure has become virtually innocuous. We recommend that 26-gauge spinal needles be widely adopted as the sta...
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is routinely performed for establishing tissue diagnosis in patients with gastrointestinal tumors. The concept of delivering chemotherapy based on molecular markers and the ability to establish a reliable diagnosis in lieu of an onsite cytopathologist has fuelled the recent trend in procuring core tissue by means of EUS-guided fine n...
Thyroid large needle aspiration biopsy is disregarded because it is thought to be associated with pain. This is in contrast with our 32 years long experience. We surveyed reports of pain in patients examined with fine needle aspiration biopsy (78, 87.2% women, mean age 59 years) or FNAB+large needle aspiration biopsy (48, 87.5% women, mean age 60 years). Each patient was questioned regarding a)...
proportionating system was dismantled and a gas leak found in the Cambridge Bourdon tube type dialysate temperature gauge which caused the needle pointer to register about 20'C too low. The fault had come on over a period of time and, unfortunately, it had been assumed that the Cambridge gauge was indicating the true dialysate temperature. Therefore the back-up temperature alarm system and the ...
