Role of high-resolution ultrasound in guiding treatment of idiopathic plantar fasciitis with minimally invasive techiniques
2007
The aim of this study was to assess the reliability of peri-fascial oedema as a sonographic criterion for selecting the most appropriate treatment (ultrasound-guided corticosteroid injection or ultrasound-guided extracorporeal shock wave therapy) of idiopathic plantar fasciitis (IPF).Sixty-four patients with a clinical diagnosis of unilateral refractory IPF, treated conservatively for at least 8 weeks, were studied with high-resolution ultrasound (HRUS). Pain intensity was evaluated with a visual analogue scale (VAS). HRUS was used to confirm IPF and identify the presence of peri-fascial oedema. Patients with an HRUS diagnosis of IPF were grouped according to the presence (A) or absence (B)…
Assistance of intraoperative microvascular Doppler in the surgical obliteration of spinal dural arteriovenous fistula: cases description and technica…
2003
BACKGROUND: Intraoperative microvascular Doppler may be valuable in assisting in the surgical obliteration of dural arteriovenous fistula of the spinal cord. It enables identification, through flow spectrum analysis, of the anatomic components and haemodynamic features of this type of vascular malformation. METHODS: In two cases, intraoperative microvascular Doppler was used to assist in the surgical obliteration of dural arteriovenous fistula of the spinal cord. The fistulas were identified prior to the dura opening, and for this only minimally invasive surgery was required. Direct recordings of the arterialised draining vein and the nidus of the fistula demonstrated a pathological spectru…
Is Transcranial Magnetic Resonance Imaging-Guided Focused Ultrasound a Repeatable Treatment Option? Case Report of a Retreated Patient With Tremor Co…
2019
Introduction In recent years, transcranial Magnetic Resonance Imaging-guided Focused Ultrasound (tcMRgFUS) treatments for functional neurological disorders are giving a new thrust to the field of therapeutic brain lesioning. Objective To present the case of a patient affected by tremor combined with Parkinsonism who underwent a second tcMRgFUS thalamotomy because of relapsing tremor after a few months from the first tcMRgFUS treatment. Methods A 72-yr-old, right-handed man, came to our observation because of a disabling tremor affecting his upper limbs, refusing any invasive surgical procedure and already treated by tcMRgFUS left Vim thalamotomy. However, clinical benefit had brief duration…
Ultrasound-Assisted Catheter-Directed Thrombolysis in High-Risk and Intermediate-High-Risk Pulmonary Embolism: Results From a Single-Center Cohort
2016
We present our single-center results on ultrasound-assisted thrombolysis (USAT) in patients with pulmonary embolism (PE) at intermediate high risk (IHR) and high risk (HR). Our study consisted of 75 patients with PE who underwent USAT (60 at IHR and 15 at HR). The median time delay from symptoms to USAT was 5 days. Ultrasound-assisted thrombolysis resulted in improvements in tricuspid annular plane systolic excursion; pulmonary artery (PA) systolic and mean pressures; Qanadli score; right to left ventricle diameter ratio and right to left atrial diameter ratio; and diameters of main, right, and left PA regardless of the baseline risk status ( P < .0001 for all). Death was documented in …
Reproducible coronary plaque quantification by multislice computed tomography
2007
BACKGROUND: The aim of this study was to investigate reproducibility and accuracy of computer-assisted coronary plaque measurements by multislice computed tomography coronary angiography (QMSCT-CA). METHODS AND RESULTS: Forty-eight patients undergoing MSCT-CA and coronary arteriography for symptomatic coronary artery disease and quantitative intravascular ultrasound (IVUS, QCU) were examined. Two investigators performed the QMSCT-CA twice and a third investigator performed the QCU, all blinded for each other's results. There was no difference found for the matched region of interest (ROI) lengths (QCU 29.4 +/- 13 mm vs. QMSCT-CA 29.6 +/- 13 mm, P = 0.6; total length = 1,400 mm). The compari…
The prognostic role of CMR using global planimetric criteria in patients with excessive left ventricular trabeculation.
2021
Objectives: Although cardiovascular magnetic resonance (CMR) is widely used in the assessment of left ventricular non-compaction (LVNC), there are no universally accepted diagnostic criteria and limited data regarding their prognostic value. We assessed the long-term prognostic role of the planimetric global Grothoff’s criteria and of the CMR findings in predicting adverse cardiovascular events (CE). Methods: We prospectively enrolled 78 patients (46.7 ± 18.7 years, 33.3% females) with documented positive Jenni’s echocardiographic criteria for LVNC. Cine images were used to quantify function parameters and to assess for the presence of all four quantitative Grothoff’s criteria (global Groth…
Noninvasive Visualization of an Apparent Patent Intracoronary Stent by Transesophageal Echocardiography
1995
In the area of increasing interventional techniques there is a need for noninvasive imaging modalities to provide postinterventional follow-up. We were able to visualize the apparent patency and measure the dimensions of an intracoronary Palmaz-Schatz stent in the left circumflex coronary artery using transesophageal two-dimensional echocardiography. This report indicates the potential of echocardiography to directly assess coronary stents.
A clampless and sutureless aortic anastomosis technique using an endograft connector for aortoiliac occlusive disease in which the aorta cannot be cl…
2012
Bypass surgery in aortoiliac or aortofemoral occlusive disease can be technically demanding and hazardous due to huge calcifications and/or patient co-morbidities. We report about mid-term results of a telescoping sutureless aortic anastomosis technique using endografts as connectors to address such challenging situations. This is a single-center experience (2004–2011) in seven patients (63 ± 6 years) requiring aortoiliac (three) or aortofemoral (four) bypass surgery. In six cases, an aortic stent graft was telescoped into the infrarenal aorta and partly deployed within the aorta and partly outside the aorta. In the first case, a bifurcated stent graft was deployed and the iliac legs were …
Outpatient endovascular aortic aneurysm repair: Experience in 100 consecutive patients
2013
OBJECTIVES:: To present the safety, feasibility, costs, and patient satisfaction of outpatient endovascular aneurysm repair (EVAR). BACKGROUND:: Our experience in more than 1000 patients indicated that in technically uncomplicated EVAR procedures, the only need for hospitalization was for access vessel complications (bleeding or occlusion) requiring secondary procedures. These complications could always be identified within the first 3 hours after EVAR. METHODS:: Two-center retrospective analysis of prospectively gathered data on 100 consecutive elective outpatient EVAR cases (Outpt EVAR). Inclusion criteria for Outpt EVAR were as follows: asymptomatic clinical state, informed consent, trav…
Temporal retrogasserian resection of trigeminal root versus controlled elective percutaneous electrocoagulation of the ganglion of gasser in the trea…
1972
In his experience with 531 surgical procedures for the relief of trigeminal neuralgia between 1955 to 1970, the author developed a strong preference for the percutaneous electro-coagulation of the gasserian ganglion. Although the method was repeatedly modified in the early years, a standardized technique of controlled, selective and fractional coagulation in the semiawake state of neurolept-anaesthesia was used since 1963 in 183 of his 311 patients, treated in this manner. The advantages of the method, particularly in comparison to open intracranial root sections, are: Minimal operative risk, control of operative effect during the operation, small sensibility deficit, low rate of complicati…
