THROMBUS FORMATION ON DISRUPTED PLAQUES

2014-03

A. Yamashita and Y. Asada

Acute cardiovascular events that usually involve thrombus formation at sites of disrupted atherosclerotic plaques are currently described as atherothrombosis. Thrombosis is a major complication of atherosclerosis and also a rare but serious complication after stent implantation. However, it does not always result in complete thrombotic occlusion with subsequent acute symptomatic events (1). Therefore, thrombus growth is critical to the onset of clinical events. Thrombus formation is probably modulated by the thrombogenicity of exposed plaque constituents, local hemorheology, systemic thrombogenicity and fibrinolytic activity. Although the mechanisms of thrombus formation have been intensively investigated, little is known about either the mechanisms involved in thrombogenesis or thrombus growth after plaque disruption and stent implantation. This article examines the pathology of atherothrombosis, including late drug-eluting stent (DES) thrombosis, and recent advances in the understanding of thrombogenetic mechanisms and thrombus growth on atherosclerotic lesions, especially coronary atherothrombosis.

ENDOTHELIAL DYSFUNCTION AND INFLAMMATION

2014-03

M. Slevin and G. McDowell

Conventional based methods of catheter removal of arterial blockages formed during the process of atherosclerosis often result in production of a series of rapidly occurring events which follow the balloon catheter-induced tearing of the existing atherosclerotic plaques and concomitant arterial damage and luminal destruction and ending with significant lumen narrowing within a period of around 6 months (between 4-10% of cases following endarterectomy and approximately 33% of cases in coronary arteries for example; Fig. 1).

The more recent introduction of stents has helped to resolve/reduce some of the problems associated with balloon angioplasty, in that it provides a scaffold which can prevent constriction from the intima, and when coated with anti-proliferative or anti-inflammatory drugs, can significantly slow down the process of in-stent restenosis. However, angiographic restenosis (>50%) and clinical symptomatic restenosis still occurs in 20-30% and 10-15% of patients respectively in the first year after treatment (1), and evidence has shown that there is no significant difference in long-term (3-5 years) follow up regarding subsequent myocardial infarction and death (2).

The Use of Ultrasonic Aspirator in the Surgery of the Fibrous Dysplasia Involving the Skull Base

Craniofacial fibrous dysplasia is a non-malignant disease. It appears due to the mutations of the GNAS gene that results in inhibition of the differentiation and proliferation of bone-forming stromal cells and leads to the replacement of normal bone and marrow by fibrous tissue and woven bone. Sometimes it is isolated to a single or multiple skeletal sites and / or endocrine organ (1, 2, 3, 4).

The disease commonly progress as a slow developing mass. Distortion of optic nerve, eye ball, nasal airway, facial nerve, teeth and middle year ossicles can occur. In young patients, at prepubertal age, the growth is rapid and can cause aneurismal bone cysts or mucoceles (1, 3, 5). The malignant change to osteosarcoma or other form of sarcoma can appear in less than 1% of cases (1, 2).

The Inferior Gluteal Flap - Breast Reconstruction - Anatomic Dissection on a Cadaver

2014-03

S. Cortan, I. Lascar, I.P. Florescu, M. Valcu, Ioana Teona Sebe

The breast has been the expression of beauty and fertility since ancient times. The aesthetic reconstruction of the breast is and has been a challenge for plastic surgeons. Microsurgical techniques of dissection and free transfer are commonly used.

During the dissection of one fresh, female cadaver, age 67, a free inferior gluteal flap was taken from gluteal region, using loupe magnification. The dissection preparations were photographed with a high definition camera.

POSTERIOR PELVIC EXENTERATION FOR ADVANCED, UNRESPONSIVE TO RADIATION THERAPY CERVICAL CANCER - A CASE REPORT

2014-03

N. Bacalbașa, Irina Bălescu

Although pelvic exenterations represent aggressive surgical procedures which might associate physical and psychological problems and a worsened body image, they are the only potential solution with curative intent in centro-pelvic tumors originating from both digestive and gynecologic tract. (1,2,3) In selected cases preoperative oncologic treatment can offer a tumor down-staging or can diminish the tumoral invasion in adjacent organs providing this way the possibility of less aggressive surgical procedures. In other cases this desiderate cannot be obtained; the tumor proves to be unresponsive to neo-adjuvant treatment and multivisceral resections being needed in order to obtain a good control of the disease. Studies have shown that clinical features of the tumor and both molecular and non-molecular biomarkers can be responsible for the poor tumoral response at irradiation. (4) In these cases surgery remains the only treatment with curative intent. We present the case of a 62 year old patient diagnosed with a large cervical tumor in which neo-adjuvant treatment failed to obtain an acceptable control of the disease. She was addressed to our service after augmentation of the tumor under neo-adjuvant treatment; we performed a total hysterectomy en bloc with bilateral adnexectomy, total colpectomy, abdomino-perineal rectal resection and pelvic lymph node dissection with good results.
