Does Conservative Surgery for Breast Carcinoma Still Require Axillary Lymph Node Evaluation? A Retrospective Analysis of 1156 Consecutive Women With …

2016

Abstract Background The role of axillary surgery for early breast carcinoma treated with conservative surgery and radiotherapy is currently the subject of considerable investigation. Recent studies have supported the noninferiority of avoiding axillary surgery in terms of overall survival when sentinel lymph node biopsy (SLNB) presents ≤ 2 positive lymph nodes, thus sparing the patients from complications. There are some ongoing studies investigating the possibility of omitting SLNB. Axillary study seems to be sufficiently replaced by SLNB for staging the disease. Axillary surgery maintains a therapeutic role in the presence of > 2 metastatic lymph nodes at SLNB. Patients and Methods We per…

Echocardiography in diagnosis of aortic dissection.

1989

In a multicentre study the accuracy of echocardiography was measured in 164 consecutive patients with suspected aortic dissection. The diagnosis was subsequently proven (82 patients) on the basis of transthoracic and transoesophageal echocardiography and additional diagnostic procedures, including computed tomography (CT), aortic angiography, and surgery and/or necropsy. The sensitivity and specificity of echocardiography were 99% and 98%, respectively, with positive and negative predictive values of 98% and 99%. For CT sensitivity was 83%, specificity 100%, and positive and negative predictive values 100% and 86%, respectively. For aortography sensitivity and specificity were 88% and 94%, …

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 …

Bilateral vertebral artery dissection, agenesis of both ICAs, and connective tissue aberrations

2013

A 35-year-old woman presented with acute signs of stroke (appendix e-1 on the Neurology® Web site at [www.neurology.org][1]). After initial CT with angiography, MRI with time-of-flight angiography confirmed agenesis of both internal carotid arteries (ICAs; figure 1A). It revealed bilateral vertebral artery (VA) dissections and ischemias in both middle artery territories (figure 1, A–E). Skin biopsy microscopy (figure 2) was consistent with ultrastructural connective tissue disease (uCTD), for which no further evidence was found apart from mild hypermobility of the finger joints. The underlying uCTD with structural instability of the arterial walls and the increased blood flow in the vertebr…

Is it really useful the Harmonic scalpel in axillary dissection for locally advanced breast cancer? A case series.

2017

Background. The seroma is one of the most common complications in the axillary lymph nodal dissection (different surgical approaches have been tried to reduce the seroma incidence). In our study we evaluate the outcome of patients using or not the ultrasonic scalpel (Harmonic scalpel) according to a standardized surgical technique. Patients and Methods. From January 2011 to December 2015 120 patients underwent axillary dissection for breast cancer. Patients were divided in two groups: patients belonging to the first group underwent Harmonic scalpel dissection and patients belonging to the second group underwent classical dissection. Each group consisted of 60 patients. Quadrantectomy (QUAD)…

The Smith-Robinson Approach to the Subaxial Cervical Spine: A Stepwise Microsurgical Technique Using Volumetric Models From Anatomic Dissections.

2020

BACKGROUND: The Smith-Robinson1 approach (SRA) is the most widely used route to access the anterior cervical spine. Although several authors have described this approach, there is a lack of the stepwise anatomic description of this operative technique. With the advent of new technologies in neuroanatomy education, such as volumetric models (VMs), the understanding of the spatial relation of the different neurovascular structures can be simplified. OBJECTIVE: To describe the anatomy of the SRA through the creation of VMs of anatomic dissections. METHODS: A total of 4 postmortem heads and a cervical replica were used to perform and record the SRA approach to the C4-C5 level. The most relevant…

COMPUTATIONAL FLUID DYNAMICS OF TYPE B AORTIC DISSECTION

2014

Type B aortic dissection (AoD) is a disease connected to high blood load on the aortic wall and to a reduced aortic wall resistance. Nowadays, prognosis on type B AoD results to be particularly difficult with an high incidence of patients treated with medical therapy which manifest complication connected with dissection and which should have been treated with surgical repair immediately. This work aims to study those haemodynamical and morphological proprieties of dissected aorta, which can influence the progression or stability of type B AoD. Computational fluid-dynamic analyses were performed on twenty-five patients with type B AoD, whose nine presented an aneurysm evolution and sixteen p…

RUPTURE OF AN AORTIC DISSECTION INTO THE RIGHT ATRIUM IN A PATIENT WITH PREVIOUS AORTIC VALVE REPLACEMENT: A CASE REPORT

2005

We report the case of a 73-year-old man with a history of previous aortic valve replacement in 1990 and rupture of an aortic dissection into the right atrium. The patient was admitted to the emergency room because of chest pain, stopped not long after. The electrocardiogram did not show any signs of ischemia and myocardial enzymes were not increased. Transthoracic echocardiography revealed aortic root dilation (maximum diameter 60 mm) extended to the aortic arch, and the presence of a flow from the ascending aorta to the right atrium (evocative of a fistula between the two chambers). The aortic valvular prosthesis function was good. Transesophageal echocardiography confirmed an aorta-right …
