Pneumothorax Induced by Computed Tomography Guided Transthoracic Needle Biopsy: A Review for the Clinician.

Percutaneous computed tomography (CT)-guided transthoracic needle biopsy (TTNB) is a valuable procedure for obtaining tissue or cells for diagnosis, which is especially indispensable in thoracic oncology. Pneumothorax and hemoptysis are the most common complications of percutaneous needle biopsy of the lung. According to reports published over the past decades, pneumothorax incidence in patients who underwent TTNB greatly varies. The morbidity of pneumothorax after CT-guided TTNB depends on several factors, including size and depth of lesions, emphysema, the number of pleural surfaces and fissure crossed, etc. Attention to biopsy planning and technique and post-biopsy precautions help to prevent or minimize potential complications. Many measures can be taken to help prevent the progression of a pneumothorax, which in turn might reduce the number of pneumothoraces requiring chest tube placement. A multitude of therapeutic options is available for the treatment of pneumothorax, varying from observation and oxygen treatment, simple manual aspiration, to chest tube placement. When a pneumothorax develops during the biopsy procedure, it can be manually aspirated after the needle is retracted back into the pleural space or by inserting a separate needle into the pleural space. Biopsy side down positioning of the patient after biopsy significantly reduces the incidence of pneumothorax and the requirement of chest tube placement. Aspiration in biopsy side down position is also recommended for treating pneumothorax when simple manual aspiration is unsuccessful or delayed pneumothorax occurred. Chest tube placement is an important treatment strategy for patients with a large or symptomatic pneumothorax. Clinicians are encouraged to understand the development, prevention, and treatment of pneumothorax. Efforts should be made to reduce the incidence of pneumothorax in biopsy planning and post-biopsy precautions. When pneumothorax occurs, appropriate treatment should be adopted to reduce the risk of worsening pneumothorax.

Identification of the biopsy track in musculoskeletal tumour surgery

Local recurrence along the biopsy track is a known complication of percutaneous needle biopsy of malignant musculoskeletal tumours. In order to completely excise the track with the tumour its identification is essential, but this becomes increasingly difficult over time. In an initial prospective study, 22 of 45 patients (48.8%) identified over a three-month period, treated by resection of a musculoskeletal tumour, had an unidentifiable biopsy site at operation, with identification statistically more difficult after 50 days. We therefore introduced the practice of marking the biopsy site with India ink. In all 55 patients undergoing this procedure, the biopsy track was identified pre-operatively (100%); this difference was statistically significant. We recommend this technique as a safe, easy and accurate means of ensuring adequate excision of the biopsy track.

Arterial Air Embolism: A Rare but Life-Threatening Complication of Percutaneous Needle Biopsy of the Lung

Arterial Air Embolism: A Rare but Life-Threatening Complication of Percutaneous Needle Biopsy of the Lung

Acute Renal Failure After Biopsy of a Transplant Kidney

AbstractPercutaneous biopsies of renal allografts are performed frequently, mostly for clinical indications and occasionally as protocol biopsies in some transplant centers. A rare complication of percutaneous needle biopsy is the development of a subcapsular hematoma, also known as Page kidney. The authors report such a case in a renal allograft following biopsy. What makes this case remarkable is the spontaneous resolution of the hematoma without surgical intervention, with reasonable recovery of allograft function, allowing cessation of dialysis.

Air Embolism Detected During Computed Tomography Fluoroscopically Guided Transthoracic Needle Biopsy

Air embolism is a rare but potentially fatal complication of percutaneous needle biopsy of the lung. We report a case of cerebral air embolism which occurred during computed tomography (CT)-guided needle biopsy. Air entering the aorta is depicted on CT-fluoroscopy images of the procedure.

Percutaneous needle biopsy of the lung and its impact on patient management.

Percutaneous needle biopsy (PNB) of the lung is a commonly performed procedure, mainly used for the investigation of solitary pulmonary nodules. Developments in imaging, particularly computed tomography (CT), have enable accurate preliminary assessment and targeting of lesions. Improvements in needle design ensure the provision of diagnostic samples for both cytologic and histologic assessment; and the development of immunocytochemistry and immunohistochemistry have allowed improved accuracy in diagnosis. A significant improvement in diagnostic accuracy for benign lesions has been associated with the use of cutting needles that provide cores for histologic diagnosis, in contrast to cytologic analysis from fine-needle aspiration. The complications of PNB are well recorded and have not changed significantly with the newer imaging techniques and needles. The preliminary assessment of solitary pulmonary nodules, and the pretest likelihood of malignancy, has improved using contrast-enhanced CT and positron emission tomography; the latter modality is increasingly having a major impact on the investigation of patients with suspected malignancy. The performance of PNB must always be determined on an individual case basis and when the result is likely to affect management. The complementary roles of PNB, bronchoscopic biopsy, and video-assisted thoracoscopic biopsy continue to evolve.

Case report: Cutaneous seeding following fine needle biopsy of colonic liver metastases

Needle track seeding is a rare complication of percutaneous needle biopsy which has become less frequent with the advent of the fine needle. We describe one case of malignant cutaneous seeding following fine needle aspiration of a peripherally based hepatic metastasis from colonic carcinoma. This report underlines the need to traverse normal adjacent liver parenchyma prior to entering a peripherally-based metastatic deposit to reduce the likelihood of malignant cutaneous seeding.

Angiographic changes due to needle biopsy of the liver.

Symptomatic complications of percutaneous needle biopsy of the liver are uncommon, however, they are occasionally demonstrated on postbiopsy angiograms. Angiographic findings include needle tracts, arteriovenous fistulas, hematoma, and aneurysms and pseudoaneurysms. These complications were not serious and except for hematoma required no further treatment.
