ABSTRACT
Abstract High-resolution ultrasound is the imaging method of choice for the evaluation of thyroid nodules. The method has recently come to be used widely and often, which has increased the rate of thyroid nodule detection. In 2017, the American College of Radiology (ACR) established a risk-stratification system designated the Thyroid Imaging Reporting and Data System (TI-RADS) to be a practical guide for widespread use, with a single lexicon and standardization of ultrasound reports of thyroid nodules. The objective of this study was to present a practical approach, using examples to illustrate the criteria evaluated by the 2017 ACR TI-RADS, in order to help minimize uncertainties regarding its application by sonographers.
RESUMO A ultrassonografia de alta resolução é a modalidade de escolha para avaliação de imagem dos nódulos tireoidianos, e sua recente aplicação ampla e difusa tornou a detecção de nódulos tireoidianos mais frequentes. O American College of Radiology (ACR) estabeleceu um sistema de estratificação de risco denominado Thyroid Imaging, Reporting and Data System (TI-RADS) para ser um guia prático para utilização ampla com um léxico único e padronização de relatórios ultrassonográficos de nódulos tireoidianos. O objetivo deste trabalho é fazer uma abordagem prática com base em exames para ilustrar e exemplificar os critérios avaliados pelo TI-RADS-ACR 2017, a fim de ajudar a reduzir os pontos de dúvidas de sua aplicação pelos profissionais ultrassonografistas.
ABSTRACT
A escleroterapia continua sendo um dos procedimentos mais executados pelos cirurgiões vasculares brasileiros. O conhecimento das suas complicações é imprescindível para que possamos evitá-las. Os efeitos colaterais graves desse método de tratamento para as telangiectasias dos membros inferiores são raros e frequentemente associados a um erro técnico ou à dosagem injetada. São predominantemente locais, apresentando-se, algumas vezes, como uma situação de difícil resolução. Relatamos um caso de formação de necrose cutânea após escleroterapia química com glicose hipertônica (75%) e sua cicatrização utilizando preparação tópica contendo vaselina e glicose 60%, cujo resultado estético foi satisfatório
Sclerotherapy remains one of the procedures most frequently performed by Brazilian vascular surgeons. Knowledge of its complications is indispensable to enable us to avoid them. The severe side effects of this method of treatment for telangiectasias of the lower limbs are rare and are often associated with technical errors or the dose injected. Complications are predominantly local, but are sometimes difficult to resolve. We report a case of formation of cutaneous necrosis after chemical sclerotherapy using hypertonic glucose (75%), which healed when treated with a topical preparation containing vaseline and 60% glucose, with satisfactory esthetic results

Due to advancement of non-surgical methods of coronary revascularization the patients referred for surgery have extensive and complex coronary anatomy. Patients with diffuse atheromatous coronary artery disease required coronary artery reconstruction or coronary endarterectomy [CE]. Coronary endarterectomy on beating heart needs skill and better surgical technique. Coronary endarterectomy along with coronary artery bypass grafting [CABG] done on beating heart is compared with coronary endarterectomy done by using conventional CABG technique. Seven hundred and ninety five consecutive patients underwent CABG from January 2006 to March 2007 in a prospective randomized trial at cardiac surgery department, Punjab Institute of Cardiology, Lahore; out of these 115 patients underwent coronary endarterectomy [CE] and were included in this study. Coronary artery bypass grafting was performed in 115 patients. Seventy two [62.6%] were in group A on-pump and 43 [37.39%] were in group B off-pump. Mean age in group A was 55.68 +/- 1.06 and 52.63 +/- 1.40 in group B. Sixty six male and 6 female were included in group A, 40 male and 3 female patients were in group B. In-hospital mortality among patients undergoing CABG was 5.6% in on-pump group and 2.3% in offpump group [p=0.649], the duration of post-operative mechanical ventilation in on-pump was 6.78 +/- 9.34 hours and 5 +/- 4.0 hours in off-pump group [p=0.060], 66.7% patients in on-pump and 58.1% patients in off-pump group required blood transfusions, Intra-aortic balloon pump [IABP] was required in 5.6% of the patients in on-pump group. Other factors included, smoking 26.4% in on-pump and 41.9% in offpump group [p=0.01], Intensive care unit [ICU] stay was statistically significant 4 +/- 3 in on-pump group and 4 +/- 2 in off-pump group [p=0.02], and drain in on-pump group was 455 +/- 208 ml and 540 +/- 370 ml in off-pump group [p=0.01]. Coronary endarterectomy [CE] has higher post-operative morbidity and mortality but the post-operative outcome after the procedure on either technique is comparable and CE is feasible on off-pump technique as well
