BACKGROUND Vascular leiomyosarcoma are rare tumors typically originating from the inferior vena cava (IVC). Due to nonspecific clinical signs most tumors are diagnosed at advanced stages. Complete surgical resection remains the only potential curative therapeutic option. Surgical strategy is particularly influenced by the level of the IVC affected. Due to the topographic relation to the renal v...

We are developing three-dimensional imaging methods to portray vascular anatomy better, including noise-free display of vessels extracted from 3-D data sets, tree-based display, and reconstruction of angiographic data (preliminary work has resulted in the successful reconstruction of aneurysms from angiographic data). Fast, interactive display permits real-time manipulation of viewing orientation.

BACKGROUND The purpose of this study was to evaluate the results of hepatectomy with inferior vena cava or hepatic vein resection, followed by vessel reconstruction with an artificial vascular graft. METHODS From 2000 to 2011, 1,434 patients underwent several types of hepatectomy at our institution. Of these, we reviewed the cases of eight patients (0.56%) who underwent hepatectomy with infer...

BACKGROUND Trauma is the third leading cause of death. In this regard, vascular injury plays a leading role in of morbidity and mortality rates. OBJECTIVES The present study aimed to assess the prevalence of vascular injuries and results of vascular reconstruction at a referral hospital in northern Iran. PATIENTS AND METHODS A retrospective observational study assessed 88 consecutive patien...

Osteotomies are commonly carried out in orthopaedic surgery, particularly in limb reconstruction. Complications are uncommon provided that sufficient care is taken and a sound technique used. We describe three cases of formation of false aneurysm after osteotomy, with acute, delayed and asymptomatic onset. The diagnosis was supported by ultrasound investigation, and confirmed by angiography. Em...

Despite carefully performed surgery, vascular defects can remain undetected within an arterial reconstruction after blood flow is restored. Failure to recognize technical errors or abnormalities can lead to vessel thrombosis and embolization. For cardiac, carotid or visceral reconstructions these events can be catastrophic. Furthermore, corrections of lesions before graft thrombosis can have a ...
