Percutaneous biopsy

Bret Taback, Priya Jadeja, Richard Ha
BACKGROUND: Recently there are efforts to use sentinel lymph node biopsy (SLNB) techniques after neoadjuvant chemotherapy (NAC) to minimize axillary surgery. However, studies have shown higher false negative rates in this scenario, which might result in inaccurate assessment of treatment response and patient prognosis as well as leaving residual disease behind. In this study, we describe the use of reflector-guided excision of the percutaneously biopsied node (PBN) as an aid to conventional SLNB and its predictor of the axillary status after NAC...

A renal artery pseudoaneurysm is a rare but important complication that can occur after renal trauma, renal biopsy, percutaneous nephrostomy, percutaneous nephrolithotomy (PCNL), and partial nephrectomy. The incidence of this potentially life-threatening complication is less than 1%, but is likely to increase with the increasing popularity of endoscopic renal procedures. We present a case of a 30-year female who underwent right PCNL for a right renal pelvic stone. Two weeks later, she presented with massive hematuria...

BACKGROUND: Salmeterol (a long acting beta2-agonist) is a chiral molecule. (RR)-salmeterol is responsible for pharmacological effect, but basic knowledge of enantioselective pulmonary pharmacodynamics and pharmacokinetics of salmeterol remains unknown. There are safety concerns with (S)-enantiomers of beta2-agonists, with suggestions that these enantiomers may increase bronchial hyperresponsivneness in asthma patients. METHODOLOGY: Horses (n = 12) received racemic (rac-) salmeterol 250 μg via inhalation...

BACKGROUND: Complications associated with diagnostic native percutaneous renal biopsy (PRB) must be minimized. While life threatening major complications has been extensively investigated, there is little discussion regarding minor bleeding complications, such as a transient hypotension, which directly affect patients' quality of life. There is also little evidence supporting the need for conventional manual compression following PRB. Therefore, this study evaluated the relationship between minor and major complications incidence in patients following PRB with or without compression...

Transthoracic computed tomography-guided core needle biopsy (TTNB) is a well-established method for diagnosing focal pulmonary lesions. However, the dangers associated with this method as well as the significant number of complications caused by it cannot be ignored. Systemic air embolism is a rare but potentially fatal complication that can accompany transthoracic needle biopsies of pulmonary lesions. In this study, we report nonfatal systemic air embolism as a complication of a transthoracic needle core biopsy of a subpleural nodule in the right upper pulmonary lobe of a patient with hemoptysis...

A retrospective study was carried out to evaluate the diagnostic accuracy and the factors influencing the diagnostic accuracy of 648 procedures of ultrasound-guided percutaneous needle biopsy (PNB) for peripheral pulmonary lesions (PPLs). We reviewed the histopathology results, the clinical records and the procedure reports of these 648 biopsies and the final diagnoses of 637 PPLs to determine the diagnostic accuracy of ultrasound-guided PNB. Factors that influenced the diagnostic accuracy were assessed by analysis of the biopsy procedures, which were classified as diagnostic cases (true-positive and true-negative) and non-diagnostic cases (false-positive, false-negative and indeterminate)...

A 60-year-old man exhibited an abnormal shadow in the right upper lobe. He was diagnosed with lung cancer by percutaneous computed tomography-guided lung tumor biopsy. Preoperative blood test showed high serum alpha-fetoprotein(AFP) and carcinoembryonic antigen(CEA) values. Right upper lobectomy was performed and histlogical diagnosis was AFP producing hepatoid adenocarcinoma with immunohistochemically positive HEP-PAR1. After the surgery, AFP and CEA values decreased to normal range.

A 67-year-old woman was referred to our hospital because of gradually increasing dyspnoea on exertion for 6 months. Chest CT scan showed subpleural parenchymal fibrotic opacities with traction bronchiectasis in the bilateral upper lung fields. Serum rheumatoid factor and myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) were positive. There was no evident reason to suspect connective tissue disease such as ANCA-associated vasculitis or rheumatoid arthritis. We performed a CT-guided percutaneous needle biopsy of the subpleural lesion that showed slight uptake on the fluorodeoxyglucose-positron emission tomography (FDG-PET) CT scan...

BACKGROUND: Adult Wilms tumor (WT, nephroblastoma) is a rare, but well-described renal neoplasm. Although inferior vena cava tumor thrombosis is present in up to 10% of Wilms tumors in childhood, only few cases of this clinical manifestation in adults have been reported. To the best of our knowledge, this is the first case of adult WT infiltrating into inferior vena cava (IVC) with concomitant distal deep vein thrombosis. CASE PRESENTATION: A 28-year-old male patient with gross hematuria and right flank pain was diagnosed with right kidney tumor penetrating to IVC...

PURPOSE: The placement of localization clips following percutaneous biopsy is a standard practice for a variety of situations. Subsequent clip displacement creates challenges for imaging surveillance and surgical planning, and may cause confusion amongst radiologists and between surgeons and radiologists. Many causes have been attributed for this phenomenon including the commonly accepted "accordion effect." Herein, we investigate the performance of a low cost surgical clip system against 4 commercially available clips...

Coaxial technique is extensively applied to facilitate percutaneous lung lesion biopsy. However, the impact of coaxial technique on diagnostic accuracy remains undecided. We reviewed 485 patients who underwent percutaneous CT-guided needle biopsies of lung lesions in our hospital. All of these biopsies were performed using either a cutting needle alone (n = 268) or a cutting needle combined with a coaxial needle (n = 217). The diagnostic accuracy and complications resulting from the two techniques were then compared...
