Background & Aims: The clinical value of T wave inversion (TWI) in the lead aVL in diagnosing coronary artery disease (CAD) remains unclear. Hence, we aim to evaluate the association between TWI in the aVL lead and the severity and location of coronary artery stenosis in elective coronary angiography. Material and Method: Electrocardiograms (ECGs) of 167 consecutive patients undergoing electiv...

Background: An imbalance of the cerebrovascular response during functional activation of the brain has been postulated as a factor in the pathophysiology of migraine. The purpose of this study was to determine the transcranial doppler sonography (TDS) diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine. Methods: This study was carried out on 46 pa...

BACKGROUND Reconstruction of upper extremity deformities continues to be a challenge to the reconstructive surgeon. Various loco regional, distant and free flaps are available for reconstruction. However, each has its own set of advantages and disadvantages. Of the commonly performed local flaps, radial artery forearm flap, and the posterior interosseus artery flap stand out prominently. Rec...

three major arteries normally originate from the aortic arch. variations of the aortic arch branches are observed in some cases. rare variation of the aortic arch branches is originated from the retroesophageal right subclavian (rrs) artery as the last branch of the aortic arch. variation of artery is possibly associated with the variation of the recurrent laryngeal nerve. this research provide...

One of the newest ways of surgery is known as Minimally Invasive Surgery (MIS), which in spite of its benefits, because of surgeon's tactile sensing omission, causes some problems with detection of arteries and their exact positions in tissue during a surgery. In this study, tactile detection of an artery in tissue has been modeled by finite element method. In this modeling, three 2D models of ...

introduction: we did this study because there were a few studies about aorto-branch junction. methods: four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. results: based on the results, there is only one cell type in the tunica intima of endothelium in both arteries. in ab...

coronary artery calcium scoring (cacs) is a reasonable test for patients with the possibility of atherosclerosis. it can also be used for reclassifying the coronary artery disease (cad) to the high-risk status by higher cacs and subsequently modifying the management of the patients.the purpose of this study was to investigate the association of cacs to the severity of coronary artery disease in...

spontaneous coronary artery dissection is a rare cause of acute coronary syndrome and sudden cardiac death. we report coronary artery dissection in a 36-year-old woman with retrosternal chest pain 2 weeks after abortion. electrocardiography showed st elevation in leads v2-v4 and st depression in the inferior leads. lab data were normal. cardiac catheterization showed a suspicious thrombotic les...

conclusion our study revealed that the hypoplastic umbilical artery group’s non-dominant cia had higher ri values than the contralateral dominant cia. results eleven of the 165 patients (6.7%) demonstrated a hypoplastic umbilical artery. second-trimester us showed median dominant and non-dominant cia pi values of 1.43 and 1.60 (p = 0.062), respectively, and median dominant and non-dominant cia ...

background one of the most important causes of mortality in developed and developing countries is coronary artery disease. coronary artery disease (cad) may develop by deposition of lipid, fibrous or calcified debris on the surface of the coronary artery lumen. fibrous plaque and calcified plaque may cause substantial stenosis of coronary arteries leading to ischemia of heart muscle while lipid...
