RESUMO
Background: Vertebral artery is the first branch of subclavian artery .It is an important source of blood supply to the brain. Accurate knowledge of normal and variant arterial anatomy of vertebral artery is important for clinical procedures and vascular radiology as its injury may occur at the time of cervical fracture or dislocation. The present study was done to study variant origins of vertebral artery. Aims & Objective: To study the variant origins of vertebral artery. Materials and Methods: The present study was done on thirty human cadavers to know the variant origin of vertebral arteries by Dissection method. Results: In the present study, variant origin of Left Vertebral Artery (LVA) was found in one male (3.33%) cadaver out of 30 cadavers. There was aortic origin of Left Vertebral Artery (LVA) instead of left subclavian artery. Conclusion: An understanding of anomalous origin of vertebral artery is very much important while performing diagnostic and interventional angiography & clinical improvements before vascular surgeries of supraaortic arteries.
RESUMO
Background: The brachial artery begins as the continuation of 3rd part of axillary artery at the distal border of teres major muscle. It terminates about a centimetre below the elbow joint at the level of neck of radius into radial and ulnar arteries. Context & purpose of study: The present study was done on 30 cadavers in department of anatomy to find out any variations in division pattern of the brachial artery. Results: Variations were found in two cadavers. An unusual short segment of the brachial artery which divide at middle of arm was found in right upper limb of one cadaver. There was a high origin of the radial artery from axillary artery found in right upper limb of one cadaver. The variations can be explained on the basis of embryological development. conclusions: The knowledge of branching pattern of brachial artery is useful for physicians, surgeons, nephrologists, radiologist and interventionist in various surgical procedures and also for diagnostic and therapeutic approaches.
RESUMO
Background: Metallo-β-lactamase (MBL) mediated resistance to carbapenem is an emerging threat in Pseudomonas isolates. The aim of this study is to detect metallo-β-lactamase producing isolates of Pseudomonas spp. from various clinical samples from indoor patients in a teaching hospital. Materials and Methods: Total 900 bacterial strains were isolated from different clinical samples from indoor patients. The bacterial strains were isolated and identified as per the standard guidelines. Amongst them 100 isolates of Pseudomonas were taken for the present study. All pseudomonas isolates were subjected to antimicrobial susceptibility testing by Kirby-Bauer disc diffusion method (CLSIs). In all imipenem resistant isolates of Pseudomonas spp., MBL detection was carried out by Imipenem-EDTA combined-disc synergy test (CDST). Results: Out of 100 isolates of Pseudomonas, 44 (44%) were imipenem resistant. Of these 44 isolates, 30 were producing MBL enzyme. 30 MBL positive isolate included 12 (40%) from surgical wards, 10 (33.33%) from tuberculosis ward, 4 (13%) from medicine ward, 2 (7%) from paediatric ward, 1 (3%) from urology ward and 1 (3%) from neonatal ICU. All MBL positive strains were resistant to β-lactams, aminoglycosides and fluoroquinolones. Conclusion: Prevalence of MBL producing Pseudomonas spp. is 30%. The MBL producing Pseudomonas spp. isolates were multidrug resistant. It is important to identify MBL producing pseudomonas isolates in laboratory as may cause serious infections and may cause a nosocomial outbreak.
