BACKGROUND This study evaluated cervical lymph node metastases at level IIb in cases of hypopharyngeal cancer and analyzed the possibility of preservation of level IIb during neck dissection. METHODS In total, 34 patients (51 neck sides) with hypopharyngeal cancer that underwent neck dissection from April 2008 to April 2011 were retrospectively analyzed. We evaluated the distribution of metas...

BACKGROUND Conventional radical neck dissection often causes a variety of complications. Although the dissection method has been improved by retaining some tissues to reduce complications, the incomplete dissection may cause recurrence of disease. In the present study, we developed a novel radical neck dissection, which preserves the external jugular vein, the greater auricular nerve, and the d...

Iatrogenic acute dissection of the ascending aorta is a serious but rare complication of cardiac catheterization and percutaneous coronary intervention (PCI). Although treatment of ascending aortic dissection may require surgical repair, stenting at the origin of the dissection area may be sufficient in aortocoronary dissection (AD) following PCI. Described is the case of a 64-year-old female p...

AIM Aortic dissection is a life-threatening aortic catastrophe where layers of the aortic wall are separated allowing blood flow within the layers. Propagation of aortic dissection is strongly linked to the rate of rise of pressure (dp/dt) experienced by the aortic wall but the hemodynamics is poorly understood. The purpose of this study was to perform computational fluid dynamics (CFD) simulat...

This video is an interesting case detailing complex patient with superior mesenteric artery dissection causing chronic ischemia. The technical aspects of the as well presentation are showing in detailed operative video. eyJraWQiOiI4ZjUxYWNhY2IzYjhiNjNlNzFlYmIzYWFmYTU5NmZmYyIsImFsZyI6IlJTMjU2In0.eyJzdWIiOiIyOGFjNDIyNTJmYzBmZGRjMzUwYTA3MjE0ZjIxNWY5OSIsImtpZCI6IjhmNTFhY2FjYjNiOGI2M2U3MWViYjNhYWZhN...

The central role that human dissection has long held in clinical education is being reevaluated in many institutions. Despite the impression that many institutions are abandoning dissection, very few have and most of those have reinstated dissection within a few years. What are the inherent qualities that lead institutions back to dissection? In our efforts to redesign a shortened dissection co...

OBJECTIVES Intramural haematoma is defined pathologically as aortic dissection without an intimal tear. We therefore believe that this term is inappropriate as an acute clinical diagnosis, and instead, use the term 'thrombosed-type acute aortic dissection'. We compared the features of thrombosed-type acute aortic dissection with those of classic dissection. METHODS Thrombosed type was defined...

A cohort study was performed using the International Registry of Acute Aortic Dissection (IRAD) from February 1, 1998 to 28, 2018. Of 9707 patients enrolled in IRAD, 29 (0.3%) had experienced aortic dissection during pregnancy or <3 months postpartum. 105 women aged <35 years, related 20 (19%). Approximately one half type and half, B dissection. Aortopathy present (69%) their relatives (Marfan ...

We describe three cases of extracranial vertebral artery dissection that are unusual in both their modes of presentation and their associations with other pathologic conditions. The first patient had Marfan's syndrome and migraine; his dissection was asymptomatic and was diagnosed by chance at the time of repeat angiography following a previous internal carotid artery dissection. The second pat...
