Flow cytometric DNA analysis of hepatic tumours on ultrasound-guided fine-needle aspirates

1992

A study was performed on a nonconsecutive series of 51 patients in order to assess the feasibility, reliability, and usefulness of flow cytometric (FCM) DNA analysis of samples obtained from benign and malignant hepatic tumours by means of ultrasound-guided fine-needle aspiration (UG-FNA). Cytological and often histological confirmation of the nature of the lesion was obtained in all cases from an expert pathologist. For FCM DNA analysis in 32 cases, it was also possible to use samples obtained at surgery from the actual tumours. There were no post UG-FNA complications, either early or late. It was possible to perform FCM DNA analysis on 6/7 (85.7%) of the benign tumour aspirates and all 44…

Presurgical Ultrasound-Guided Anchor-Wire Marking of Soft Tissue Metastases in Stage III Melanoma Patients

2001

Background. Due to increased sensitivity of diagnostic procedures, soft tissue metastases in melanoma patients are frequently detected very early. However, small sizes, deep location, or position close to vulnerable structures could render subsequent surgery quite difficult. Objective. To test the feasibility and effectiveness of presurgical ultrasound-guided anchor-wire marking of melanoma metastases. Methods. We selected melanoma patients with cytologically proven metastases in clinical stage III which were either unfavorably located or which have failed removal by previous surgery. Anchor-wire marking was performed ultrasound guided and free-hand style without the use of local anesthesia…

Ultrasound-Guided Breast-Conservative Surgery Decreases the Rate of Reoperations for Palpable Breast Cancer

2018

The purpose of this study is to verify whether the performance of ultrasound-guided quadrantectomy (USGQ) versus palpation-guided quadrantectomy (PGQ) can reduce the incidence of positive margins and if it can change the attitude of the surgeon. A retrospective study was conducted on 842 patients underwent quadrantectomy for breast cancer, 332 of them underwent USGQ, whereas 550 underwent PGQ. The histological type of the tumors and the margin status obtained with the histological examination were compared. The histological examination of the surgical specimen showed involvement of the margins in 24/842 patients (2.85%), 22 (2.61%) of them belonged to the PGQ group, and two to the USGQ gro…

Accuracy and Safety of Ultrasound-Guided Core Needle Biopsy of Soft Tissue Tumors in an Outpatient Setting: A Sarcoma Center Analysis of 392 Consecut…

2021

Simple Summary In patients with unclear soft tissue lesions, treatment planning largely depends on histology. Core needle biopsy is the diagnostic standard in these cases. The aim of this retrospective study was to investigate accuracy and safety of ultrasound guided core needle biopsy at a tertiary referral center. We show that ultrasound guided biopsy was feasible as a one stop shop procedure in an outpatient setting in 87.6% of the cases. The rate of conclusive biopsies was 88.5%. After surgical resection, the dignity, tumor type and histopathological grading of the biopsy matched one of the resection specimens in 97.2%, 92.7% and 92.5% of the cases, respectively. Major complications occ…

Ultrasound-guided percutaneous treatment of a calcific acromioclavicular joint

2020

RATIONALE Calcific tendinopathy is one of the most frequent causes of nontraumatic shoulder pain. However, intra-articular calcifications appear to be an infrequent condition. We herein report a rare case study of an intra-articular calcification of the acromioclavicular joint. PATIENT CONCERNS A 46-year-old man presented with an acute pain in the anterior superior region of the left shoulder which also radiated to the left cervical region. The man during the physical evaluation also presented severe functional limitation of the shoulder movements in all planes of motion. DIAGNOSES The diagnosis was carried out through a radiographic and an echotomographic examination, highlighting the intr…

Trans-Abdominal Ultrasound Guided ERC in a Pregnant Woman With Bile Duct Stones

2014

Background: The change in lithogenicity of bile, increased stasis of bile and decreased gall bladder emptying are the possible reasons for an increased risk of gall stones during pregnancy. However, biliary interventions during pregnancy are associated with risks to both the pregnancy and developing fetus. ERC under fluoroscopic control as gold standard is associated with higher risk of premature labor and teratogenity. Methods and patient: We performed transabdominal ultra-sound guided ERC in one patient in the second trimenon with gall stones. While the hilus area is observed by ultrasound, the papilla is carefully cannulated with a guidewire. A contrast agent is applied in the common bil…

Sonografie-gesteuerte Freihand Stanzbiopsie mediastinaler Tumoren / Ultrasound-Guided Freehand Biopsy of Mediastinal Tumors

2001

Retrospektiv wurde die Wertigkeit der sonografiegesteuerten Freihand-Biopsie bei mediastinalen Tumoren untersucht. Unter transthorakaler real-time Sonografie wurden bei 53 Patienten Biopsate nach dem core-needle-Prinzip automatisch oder manuell in Lokalanasthesie und Freihand-Technik gewonnen. Bei 52 Patienten wurde die Diagnose gesichert, in einem Fall war die Histologie erst nach Mediastinoskopie eindeutig (nodular-sklerosierendes Hodgkin-Lymphom). Komplikationen traten nicht auf. Die Methode ist zuverlassig, komplikationsarm und leicht durchzufuhren. Sie ist insbesondere bei Verdacht auf solche Erkrankungen von grosem diagnostischen Wert, bei denen die konservative Behandlung im Vordergr…

Ultrasound-guided percutaneous treatment of calcific bursitis of the medial collateral ligament of the knee

2021

Calcific bursitis of the medial collateral ligament of the knee is an infrequent pathological condition. In 1988, Kerlan and Glousman identified the clinical features of medial collateral ligament bursitis. Pain and knee functions limitation are the clinical symptoms that are most frequently encountered during the reactive inflammatory process in the bursa, that characterizes the reabsorption phases of the calcific material. It is well documented in the literature that the maximum efficacy of ultrasound-guided percutaneous treatment, with significant reduction or disappearance of symptoms, occurs precisely in this phase. The case report presented in this study confirms the validity as a the…
