Learning experiences and environments greatly influence mastery of competencies during training and in future career. From its nature, cadaveric dissection early in the medical training has the potential to daunt the student's interest in the medical profession during training and in the future clinical practice. This study aimed at appraising the Tanzanian first year medical students at Muhimb...
Total mesorectal excision (TME) is a precise dissection of the rectum and all pararectal lymph nodes within an oncologic package: the mesorectal envelope. This article is a brief description of the technical aspects of the dissection, illustrated by cadaver dissection. Here the TME dissection is organized into 6 steps to facilitate learning: (1) left retroperitoneum; (2) superior rectal and inf...
BACKGROUND Fibromuscular dysplasia (FMD) is a noninflammatory arterial disease that predominantly affects women. The arterial manifestations may include beading, stenosis, aneurysm, dissection, or tortuosity. OBJECTIVES This study compared the frequency, location, and outcomes of FMD patients with aneurysm and/or dissection to those of patients without. METHODS The U.S. Registry for FMD inv...
We report a rare case of retrograde Stanford type A aortic dissection after endovascular repair for complicated Stanford type B aortic dissection. A 45-year-old man presented with a sudden onset of back pain and was transferred to our hospital. Computed tomography demonstrated acute Stanford type B aortic dissection with lower limb ischemia. Emergency endovascular surgery was planned for repair...
Internal carotid artery (ICA) dissection is responsible for 10-20% of strokes in young and middle-aged patients. Isolated ICA dissection involving the intrapetrous carotid canal is particularly rare, and no case has been reported to describe an association between intrapetrous ICA dissection and essential thrombocythemia. We report a case of ischemic stroke in the presence of intrapetrous right...
We report a case of a type A aortic dissection with extension into the main pulmonary artery through a sinus of Valsalva fistula. Echocardiography and computed tomographic angiography of the chest were performed and bicuspid aortic valve, hemopericardium, and dilatation of the aortic root were found. A Stanford type A dissection was seen, extending to the distal transverse thoracic aorta, and t...
Extracranial carotid artery dissection may manifest as arterial stenosis or occlusion, or as dissecting aneurysm formation. Anticoagulation and/or antiplatelet therapy is the first-line treatment, but because it is effective and less invasive than other procedures, endovascular treatment of carotid artery dissection has recently attracted interest. We encountered two consecutive cases of trauma...
OBJECTIVES This study was designed to define the frequency and explanation of false negative diagnosis of aortic dissection by aortography and transesophageal echocardiography. BACKGROUND Aortography and transesophageal echocardiography have been widely utilized to diagnose aortic dissection. Previous reports have not fully addressed the reasons why these studies yield false negative results ...
Hamlet: Has this fellow no feelings of his business, that he sings at grave-making? Horatio: Custom hath made it in him a property of easiness. (Hamlet Act V, scene i) Hamlet is appalled by the gravedigger's insensitivity towards death and corpses. Horatio explains that the gravedigger is so accustomed to such things that he no longer shares Hamlet's seriousness. We contend that human dissectio...
Vertebral artery dissection (VAD) is not uncommon in the young adult population. Owing to the various clinical manifestations; the diagnosis of VAD mainly depends on imaging examinations. Ultrasound has found an increasingly wide utilization in the diagnosis of VAD because of the continuous improvement in the resolution of ultrasonic instruments and accessibility.We retrospectively collected th...
