Surface landmarks of brachial plexus: ultrasound and magnetic resonance imaging for supraclavicular approach with anatomical correlation.
ABSTRACT The present study is able to describe a certain line, under which brachial plexus (BP) lies underneath in the supraclavicular region. A line drawn between midpoint of the sternocleidomastoid muscle to the midpoint of the clavicle was considered for BP. Surface landmarks were evaluated by applying ultrasound (US) on 30 volunteers (15 female, 15 male). Axial and sagittal views of BP were taken and distances between skin and BP were measured. Coronal magnetic resonance (MR) sections were taken from 7 volunteers according to the second line after applying two fat capsules on each line. The sonographic views were seen at the same line. Mean distances from skin were found as 16.5+/-0.7 mm for male and 14.5+/-0.5 mm for female volunteers. MR images were obtained bilaterally, which were parallel and posterior from sonographic lines. Surface landmarks, as presented in this study, are simple to accomplish and are not dependent on structural variations as external jugular vein.

ABSTRACT: MRI was performed on the spinal roots, brachial and lumbar plexuses of 14 patients with chronic inflammatory demyelinating polyneuropathy (CIDP). Hypertrophy of cervical roots and brachial plexus was demonstrated in eight cases, six of whom also had hypertrophy of the lumbar plexus. Of 11 patients who received gadolinium, five of six cases with hypertrophy and one of five without hypertrophy demonstrated enhancement. All patients with hypertrophy had a relapsing-remitting course and a significantly longer disease duration. Gross onion-bulb formations were seen in a biopsy of nerve from the brachial plexus in one case with clinically evident nodular hypertrophy. We conclude that spinal root and plexus hypertrophy may be seen on MRI, particularly in cases of CIDP of long duration, and gadolinium enhancement may be present in active disease.Brain 08/1999; 122 ( Pt 7):1383-90. · 9.92 Impact Factor

ABSTRACT: Anesthesia of the brachial plexus has been associated with injuries to adjacent structures (e.g., pneumothorax, vascular penetration). It is not uncommon to have only partial block of the upper extremity, hindering completion of the surgical procedure. The supraclavicular lateral paravascular approach to brachial plexus anesthesia has been proposed as an effective, safe alternative to the traditional approaches to brachial plexus anesthesia. This prospective, randomized study sought to determine if the supraclavicular lateral paravascular (SCLP) approach is as effective as the transarterial axillary approach, the most common brachial plexus block used at our institution. 16/20 (80%) of SCLP blocks were good. 13/20 axillary blocks were good. The success rate with the SCLP approach was 95%. The success rate with the axillary approach was 90%. The supraclavicular lateral paravascular approach is as effective as the axillary approach.Regional anesthesia 19(1):14-7.
