The recently developed dynamic jaw technology of tomotherapy can reduce craniocaudal dose spread without much prolonging the treatment time. This study aimed to investigate the efficacy of the dynamic jaw mode for tomotherapy of breast cancer. Static tomotherapy plans of the whole breast and supraclavicular regional lymph nodes, and plans for the whole breast only were generated in 25 patients ...

Objectives: Ultrasound-guided supraclavicular and infraclavicular blocks are commonly used for upper extremity surgery. The primary aims of our study were to compare block success, block onset times and performance times; secondary aims were to compare the number of needle advancements, and incidence of adverse events of ultrasound-guided supraclavicular or infraclavicular blocks. Methods: 110 ...

BACKGROUND Surgery for clavicular shaft fractures is becoming more common but incisional and chest wall numbness reportedly occurs in 10% to 29% of patients. This may be the result of iatrogenic injury to the supraclavicular nerve branches. QUESTIONS/PURPOSES We determined if there was a predictable branching pattern of the supraclavicular nerve at the anterior clavicular border and determine...

BACKGROUND AND OBJECTIVES To assess frequency and significance of enlarged nonpalpable supraclavicular lymph nodes with routine ultrasound (US) evaluation and US-guided fineneedle aspiration biopsy (FNAB) for the diagnosis and staging of patients with lung cancer. MATERIALS AND METHODS 106 consecutive patients with lung cancer and nonpalpable supraclavicular lymph nodes were evaluated with ce...

Cervical regional nodal involvement, as the first manifestation of prostatic cancer, has been rarely reported. Prostate cancer metastasis to the supraclavicular lymph nodes with negative immunohistochemical stain of PSA is even rarer. We report a case of prostate cancer with negative immunohistochemical stain of prostate-specific antigen presenting with left supraclavicular node enlargement. A ...

The need of central vein cannulation has been increased since the case critical patients and underwent high-risk patients. Supraclavicular approach is an alternative to due fewer anatomical variance, good longitudinal view, better visualization needle during procedure, clear demarcation landmarks, larger target area, patient comfort, complications. This study presents ultrasound guided using su...

Objective To study the success rate and complication of brachial plexus block in Maharaj Nakorn Chiang Mai Hospital, Thailand. Methods The anesthetic data of brachial plexus block performed for operations on the upper extremity in the Department of Anesthesiology, Faculty of Medicine, Chiang Mai University, from January 2004 to December 2005, were reviewed and analyzed for success rate and comp...

Primary tumours of the brachial plexus are rare entities. They usually present as extrathoracic masses located in the supraclavicular region. This report describes two cases of benign schwannomas arising from the brachial plexus with an intrathoracic growth. In the first case the tumour was completely intrathoracic and it was hardly removed through a standard posterolateral thoracotomy. In the ...
