REVIEW
Jaber Mustafa, Ilan Asher, Zev Sthoeger
Upper extremity deep vein thrombosis (UEDVT) is defined as thrombosis of the deep venous system (subclavian, axillary, brachial, ulnar, and radial veins), which drains the upper extremities. It can be caused by thoracic outlet anatomic obstruction, such as Paget-Schroetter syndrome, (primary) or by central intravenous catheters (secondary). UEDVT may be asymptomatic or present with acute severe pain and arm swelling. Clinical suspicion should be confirmed by diagnostic imaging procedures such as duplex ultrasound, computed tomography scan, or magnetic resonance imaging...

In diagnosing peripheral pulmonary lesions (PPL), radial endobronchial ultrasound (R-EBUS) is emerging as a safer method in comparison to CT-guided biopsy. Despite the better safety profile, the yield of R-EBUS remains lower (73%) than CT-guided biopsy (90%) due to the smaller size of samples. We adopted a hybrid method by adding cryobiopsy via the R-EBUS Guide Sheath (GS) to produce larger, non-crushed samples to improve diagnostic capability and enhance molecular testing. We report six prospective patients who underwent this procedure in our institution...

BACKGROUND: Peripheral pulmonary lesions (PPLs) pose a diagnostic challenge, and the optimal investigation in many such cases remains unclear. Computed tomography (CT)-guided percutaneous needle biopsy (CT-PNB) has been the modality of choice for such lesions with a high diagnostic accuracy but with high rates of pneumothorax. Endobronchial ultrasound (EBUS) with a radial probe is an alternate diagnostic modality with increased diagnostic yield of bronchoscopy in the evaluation of PPL...

Fanconi anemia is a rare chromosome instability disorder with a highly variable phenotype. In the antenatal and neonatal periods, the diagnosis is usually suggested by the presence of typical congenital abnormalities such as intrauterine growth retardation, microcephaly and radial ray defects. We report a newborn female with a prenatal diagnosis of Fanconi anemia, complementation group O (FANCO). Antenatal ultrasounds identified symmetrical intrauterine growth retardation, complex heart defect as well as brain anomalies, overlapping fingers and cleft lip and palate...

A false aneurysm or pseudoaneurysm (PA) is the formation of a pulsatile and encapsulated hematoma in communication with the lumen of a perforated artery. Its origin is different but most cases are associated with a traumatic event. Currently, the referenced treatment is endovascular surgery but it is not feasible for the majority of vascular surgeons working in a tropical environment. The aim of this study was to describe the diagnostic and therapeutic aspects of arterial PA (APA) encountered in our institution and to evaluate the place of open surgical technique in their management...

Static apnea provides a unique model that combines transient hypertension, hypercapnia, and severe hypoxemia. With apnea durations exceeding 5 min, the purpose of the present study was to determine how that affects cerebral free-radical formation and the corresponding implications for brain structure and function. Measurements were obtained before and following a maximal apnea in 14 divers with transcerebral exchange kinetics, measured as the product of global cerebral blood flow (duplex ultrasound) and radial arterial to internal jugular venous concentration differences (a-vD)...

The work describes a method to quantitatively evaluate spatial resolution in B-mode quality control images as radial modulation transfer function (MTF). The method is easy to use in in-field quality assurance programs in clinical institutions, as it is fast and can be performed with the help of phantoms that are already used for routine quality control. It uses a round insert with different echogenic characteristics compared with the phantom background. The method was automated with a MATLAB® routine, which can be run in full automatic mode or with a grade of interaction by the user, as is sometimes necessary with low-quality images...
