Validity of Pelvic Autonomic Nerve Stimulation With Intraoperative Monitoring of Bladder Function Following Total Mesorectal Excision for Rectal Canc…
2005
This prospective study was designed to clarify whether the results of the intraoperative stimulation of parasympathetic pelvic nerves performed in 31 patients after mesorectal excision for rectal carcinoma allowed predictions in terms of the postoperative bladder function of the patients.After monopolar stimulation of the splanchnic pelvic nerves using a constant voltage stimulator (Screener 3625), intravesical pressure increase was measured manometrically. The results were related to the postoperative residual urine volume, requirement of recatheterization and long-term catheterization, just as to the results of the validated International Prostatic Symptom Scores and the Quality of Life I…
The value of intraoperative frozen section examination of sentinel lymph nodes in surgical management of breast carcinoma.
2009
PURPOSE: In breast cancer staging, the need for intraoperative sentinel lymph node (SLN) evaluation has still not been adequately established. This study investigates the impact of intraoperative frozen section (FS) evaluation of SLN to avoid subsequent axillary lymph node dissection (ALND) in patients with positive SLN. METHODS: A retrospective review of 364 breast cancer patients undergoing SLN biopsy with intraoperative FS evaluation of SLN was performed. RESULTS: Sensitivity and accuracy of FS examination of SLN were 76.4% and 94.2%, respectively. The sensitivity was significantly higher in larger tumors (p < 0.01). No significant correlation was found between FS and histologic type. A …
Thoracic Endovascular Aortic Repair (TEVAR) for the treatment of aortic diseases: a position statement from the European Association for Cardio-Thora…
2012
Thoracic endovascular aortic repair (TEVAR) is an emerging treatment modality, which has been rapidly embraced by clinicians treating thoracic aortic disease.1–4 Fundamentally, it is a far less invasive approach than open surgery and its availability and relative ease of application has changed and extended management options in thoracic aortic disease, including in those patients deemed unfit or unsuitable for open surgery. In the operating room, this requires considerable perceptual, cognitive and psychomotor demands on the operators. The dramatic expansion of TEVAR activity has necessarily prompted a requirement to systematically consider the indications, appropriateness, limitations and…
Current Role of Intraoperative Frozen Section Examination of Sentinel Lymph Node in Early Breast Cancer.
2020
Background/Aim: The aim of this study was to evaluate the current role of frozen section in identifying patients who could benefit from an immediate axillary lymph node dissection (ALND), following the criteria of the ASOCOG Z0011 and IBCSG 23-10 trials. Patients and Methods: A retrospective review was performed involving 2,079 patients with early breast cancer who underwent conservative surgery or total mastectomy with sentinel lymph node biopsy. Results: Sensitivity and diagnostic accuracy were 63.8% and 90.3%, respectively. Sensitivity was significantly higher (p<0.001) in finding macrometastases (81.8%) compared to micrometastases (11.9%). Frozen section was useful only in 7.7% of th…
Bispectral index changes in carotid surgery.
2010
Intraoperative monitoring of cerebral ischemia with shunting during carotid endarterectomy (CEA) remains controversial. Our objective was to evaluate the sensitivity and specificity of BIS changes during carotid clamping in relation to shunted patients in awake CEA.Eighty CEAs under cervical block were included. There were two patient groups: with clinical signs of cerebral ischemia (shunted patients) and without signs of cerebral ischemia (nonshunted patients). Data were based on bispectral index (BIS) values and neurological monitoring at different surgery time points, with special attention paid during carotid clamping. BIS values were compared between shunted and nonshunted patients. Se…
Intraoperative microvascular Doppler monitoring of blood flow within a spinal dural arteriovenous fistula: a precious surgical tool. Case report.
2001
The authors describe a case of spinal arteriovenous fistula (AVF) treated by a microvauscular Doppler–assisted surgical interruption of the arterialized vein. Microvascular Doppler monitoring represents a valid, widely available, non-invasive tool that enables identification, through flow spectrum analysis, of components of this type of vascular malformation. In this case because the location of the fistula was identified prior to opening the dura only minimally invasive surgery was required. Direct recordings of the arterialized draining vein and the nidus of the fistula demonstrated a pathological spectrum caused by the arterial supply and the disturbed venous outflow in which a high-resi…
A rare case of extra-intramedullary dorsal tanycitic ependymoma, radically removed with intraoperative neurophysiological monitoring
2015
Introduction: Tanycitic dorsal extra and intramedullary ependymoma is a rare form of tumor. From the histological point of view, these tumors show several aspects that make difficult the differential diagnosis from schwannomas and pilocytic astrocytomas. Tanycytic variant, often occurs in the thoracic tract of the spinal cord, and it is constituted by tanycites, that are typical elongated and bipolar cells that give to the tumor fibrillary aspects. Tanycitic variant has been recently characterized as a variant of ependymoma, since the 2000 World Health Organization (WHO) system. Case presentation: A 57 years old woman presented with intractable back pain often radiating to the left leg. Neu…
Prospective comparison of cardiopulmonary events during minilaparoscopy and colonoscopy under conscious sedation.
2005
BACKGROUND AND STUDY AIMS Cardiorespiratory parameters were examined throughout diagnostic minilaparoscopy procedures. The same parameters were analyzed during colonoscopy, and the data were compared. PATIENTS AND METHODS Sixty-five consecutive unselected patients undergoing minilaparoscopy (group 1: ASA I, n = 34; group 2: ASA II/III, n = 31) and 61 consecutive unselected patients undergoing colonoscopy (group 3: ASA I, n = 31; group 4: ASA II/III, n = 30) were included. Oxygen saturation (Sao (2)), heart rate (HR) and mean arterial pressure (RRm) were measured continuously, and 12-lead electrocardiography (ECG) recordings were made at specific times during each procedure. RESULTS Minor di…
Multimodal Intraoperative Neuromonitoring in Aneurysm Surgery
2017
Following aneurysmal subarachnoid hemorrhage, the primary goal of treatment is to exclude the vascular malformation from the intracranial circulation, while preserving the parent artery. In unruptured aneurysms, the decision whether to treat or observe the malformation is made on a case-by-case basis. In this regard, the ISUIA (International Study of Unruptured Intracranial Aneurysms) investigators suggested that aneurysm size and location were independent predictors for aneurysm rupture.1 ISUIA examined 1692 patients with cerebral aneurysms with a mean follow-up time of 4.1 years. Rupture rates differed depending on size and location, ranging from 0% in aneurysms <7 mm located in the in…
