OBJECTIVE: Suture granuloma, the rare complication of thyroidectomy, results from the use of nonabsorbable suture materials. Despite its typical ultrasound images and benign course, it carries utmost importance in the diff erential diagnosis of lymph nodes, recurrent nodules, and recurrence in the case of thyroid cancers. Subject and Results. Fifty four years old female patient, who underwent bilateral thyroidectomy in July 2010, was diagnosed with multinodular goiter and incidentally discovered micropapillary carcinoma (2 mm)...

Pulmonary embolism (PE) is a life-threatening condition with varied presentation and, therefore, poses clinical challenge for early diagnosis and proper management without which it carries high mortality. Previous studies on the role of endobronchial ultrasound (EBUS) in diagnosis of PE were carried out after PE was already diagnosed by computed tomography pulmonary angiography. We report a case of massive PE with shock, promptly diagnosed with bed side EBUS - Doppler study, as patient's clinical condition did not allow conventionally proposed diagnostic algorithm...

The cerebrovascular time constant (τ) theoretically estimates how fast the cerebral arterial bed is filled by blood volume after a sudden change in arterial blood pressure during one cardiac cycle. The aim of this study was to assess the time constant of the cerebral arterial bed in patients with traumatic brain injury (TBI) with and without intracranial hematomas (IH). We examined 116 patients with severe TBI (mean 35 ± 15 years, 61 men, 55 women). The first group included 58 patients without IH and the second group included 58 patients with epidural (7), subdural (48), and multiple (3) hematomas...

Imaging of pulmonary embolism (PTE) remains a great challange. Mortatity is even high. Possibilities of lung ultrasound, echocardiography, and compression leg vein sonography are discussed. Hemodynamic instable patients should achieve echocardiography at bed side with an accuracy of 90% and immeadiatly treated. In case of a suspected PTE, compression sonography of the leg veins is recommended. It can be performed within 2 min but, on average, yields a positive result in only one-half of the cases of PTE. During the last years, pulmonary sonography took root as a complementary method to MSCT either when the latter is not available or when it is contraindicated because of contrast agent allergy, renal insufficiency, or pregnancy...

A vein of Galen arteriovenous malformation (VGAM) is a rare intracranial shunt lacking a capillary bed and resulting in subsequent aneurysmal enlargement. VGAM has been previously reported to present as cardiovascular abnormalities, including increased right-sided cardiac load and pressure, cardiac dilatation, pulmonary hypertension and retrograde flow into the aortic arch. We report the first case of VGAM presenting as a gross right-sided neck swelling in a 39-week-old immediately at birth. Transthoracic echocardiography detected dilatation of the superior vena cava and innominate vein, increased right ventricular and pulmonary arterial pressure, and retrograde flow into the aortic arch...

Purpose: Vascular ultrasound (US) allows the analysis of vascular strain by speckle-tracking. This study sought to assess the extent to which vas cular strain varies between different segments of the arterial tree. Furthermore, this study aimed to investigate the reproducibility of vascular strain determination as well as of the components that contribute to the variance of vascular strain measurements in different vascular beds. Materials and Methods: Speckle-tracking was used to determine the vascular strain of the abdominal aorta (AA), the common carotid artery (CCA), the common femoral (CFA) and the popliteal artery (PA) of healthy adults...

Bedside sonography by non-radiologists is rapidly expanding, presenting modern medicine with challenging professional, medico-legal, financial and logistic aspects. In the current article, we reviewed the relevant literature describing sonography application by internal medicine practitioners and the obstacles that may interfere with large-scale integration of point of care ultrasound imaging. In conclusion, we see a great potential for clinical benefit by internists who will use bedside sonography and we recommend establishing an official training program in the fiell of bedside ultrasonography by internists...

During 6 weeks, we had 4 incidents of echocardiography machine malfunction. There were 3 in the operating room, which were damaged due to intravenous (IV) fluid spillage over the keyboard of the machine leading to burning of the keyboard electric connection, and 1 in the cardiology department, which was damagaed due to spillage of coffee on it. The malfunction had an economic impact on the hospital (about $ 20,000) in addition to the nonavailability of the ultrasound (US) machine for the cardiac patient after the incident till the end of the case and for consequent cases till the fixation of the machine...

BACKGROUND: Laser lithotripsy of vesical calculi in tetraplegic subjects with long-term urinary catheters is fraught with complications because of bladder wall oedema, infection, fragile urothelium, bladder spasms, and autonomic dysreflexia. Severe haematuria should be anticipated; failure to institute measures to minimise bleeding and prevent clot retention can be catastrophic. We present an illustrative case. CASE PRESENTATION: A tetraplegic patient underwent laser lithotripsy of vesical stone under general anaesthesia...

Diagnosis of schistosomiasis is made by demonstration of the parasite ova in stools, urine,and biopsy specimens from affected organs, or presence of antibodies to the different stages of the parasite or antigens circulating in body fluids by serologic techniques. DNA of schistosomes can now also be detected in serum and stool specimens by molecular technique.However, these tests are unable to determine the severity of target organ pathology and resultant complications. Accurate assessment of schistosome-induced morbidities is now made with the use of imaging techniques like ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI)...

BACKGROUND: Mediastinoscopy is the gold standard for preoperative mediastinal staging of patients with suspected or proven lung cancer. Since the development of endoscopic ultrasound-guided biopsy via the trachea (EBUS-TBNA), this status has been challenged. The purpose of the study was to examine whether mediastinoscopy is necessary, when EBUS-TBNA is performed in a center with (1) a high level of expertise, (2) "bed side" microscopy by a pathologist, (3) general anesthesia, and (4) achievement of representative tissue from station 4R, 7 and 4L, that is, the same mediastinal stations that mediastinoscopy gives access to...
