Jasdeep Giddie, Rachel Fisher, Andrew White
We describe a rare case of an anatomical variant of the supraclavicular nerve in the intra-operative setting of clavicle fixation for a fracture. Intra-operatively it was noted that one of the supraclavicular nerves was passing through a foramen in the clavicle shaft. A 60-year-old gentleman presented with a displaced multifragmentary fracture of the left clavicle after a fall. Plate fixation with a pre-contoured locking plate was performed under general anaesthesia. The clavicle was exposed through an infraclavicular transverse incision...

BACKGROUND: We investigated whether visual augmentation (3D, real-time, color visualization) of a procedural simulator improved performance during training in the supraclavicular approach to the subclavian vein, not as widely known or used as its infraclavicular counterpart. METHODS: To train anesthesiology residents to access a central vein, a mixed reality simulator with emulated ultrasound imaging was created using an anatomically authentic, 3D-printed, physical mannequin based on a computed tomographic scan of an actual human...

OBJECTIVE: Intraneural cysts are benign lesions located within the epineurium of some peripheral nerves and their aetiopathogenesis is controversial. Most are located at the level of the lower limbs. In the upper limbs, the most frequently affected nerve is the ulnar nerve. Suprascapular nerve entrapment syndrome due to the formation of an intraneural cyst is rare. In this article, we show a new case and perform a literature review of intraneural cysts located in the suprascapular nerve...

Blockades of the cervical plexus are established anesthesia procedures, not only in the context of operative carotid revascularizations. Recent investigations define inner sonoanatomic landmarks as well as the importance of brain nerves for innervation in the neck region. The present practice-oriented article discusses current study results, alternative techniques (ultrasound- versus landmark-guided) and fields of application (carotid desobliteration, surgery of the shoulder, ear and infraclavicular region)...

Cervical lymphadenopathy is a common indication for imaging evaluation of the neck. Besides metastatic squamous cell carcinoma of the head and neck, cervical lymphadenopathy can be due to many causes, with simple reactive lymphadenopathy on one end of the spectrum and malignant lymphadenopathy due to a distant infraclavicular primary, on the other end. A systematic approach to the cause of cervical lymphadenopathy, which includes pattern of lymph node enlargement, lymph node characteristics, systemic symptoms, and extranodal abnormalities, can be very useful in arriving at the correct diagnosis...

The axillary vein is a good site for ultrasound-guided central venous cannulation in terms of infection rate, patient comfort and its anatomical relationship with the clavicle and lungs. We compared real-time ultrasound-guided axillary vein cannulation with conventional infraclavicular landmark-guided subclavian vein cannulation in children. A total of 132 paediatric patients were randomly allocated to either ultrasound-guided axillary vein (axillary group) or landmark-guided subclavian vein (landmark group)...

Neurogenic thoracic outlet syndrome is caused by a neurologic compression of the brachial plexus before it reaches the arm. Three anatomic areas are common locations for such an entrapment because of their congenital and/or acquired tightness: the interscalene triangle, the costoclavicular space, and the retropectoralis minor space. Because the compression level usually remains unknown, the treatment is still controversial and most teams focus on only one potential site. We propose an all-endoscopic technique of complete brachial plexus neurolysis that can be divided into three parts, one for each entrapment area...

PURPOSE: Increased distal skin temperature can be used to predict the success of lateral infraclavicular (LIC) block. We hypothesized that an "eyeball test" of specific infrared thermographic patterns after LIC block could be used to determine block success. METHODS: In this observational study, five observers trained in four distinct thermographic patterns independently evaluated thermographic images of the hands of 40 patients at baseline and at one-minute intervals for 30 min after a LIC block...

Secondary neoplasia in the parotid gland is increasingly frequent. We examined outcomes from 40 years of parotid surgery to analyse patterns for metastasis, review the staging procedure and discuss management. We retrospectively examined 772 consecutive cases of parotid surgery in a university hospital between 1975 and 2015 and assessed changes in incidence and management over four decades. In all, 71% percent of patients were male and 29% were female, with a mean age of 68 years, aged between 23 and 93 years...

BACKGROUND: Deep brain stimulation is increasingly used to treat a variety of disorders. As the prevalence of this technology increases, greater demands are placed on neurosurgical practitioners to improve cosmetic results, maximize patient comfort, and minimize complication rates. We have increasingly employed subpectoral implantation of internal pulse generators (IPGs) to improve patient satisfaction. OBJECTIVE: To determine the complication rates of subpectorally placed IPGs as compared to those placed in a subcutaneous location...
