* Authors’ results were presented at the 66th Congress of Polish Surgeons Society in Warsaw (2013) According to expert consensus, cases with distal metastases, radiographic evidence of superior mesenteric vein (SMV) and portal vein abutment, distortion, tumor thrombus or venous encasement or no clear fat plane around the celiac axis, hepatic artery and superior mesenteric artery (SMA) are not t...

the hypertension is divided into two types: primary and secondary. the secondary type, is particularly due to renal and arterial origin and is mostly seen. in children the secondary hypertension caused by malignancies is rare. this is a case of abdominal rhabdomyosarcoma with malignant hypertension.

The effects of exposed pipe encasements on the local variation of hydrodynamic and sediment conditions in a river channel are examined. Laboratory experiments are performed to assess the response of water level, flow regime and bed deformation to several representative types of concrete encasements. The experimental conditions considered are: three types of exposed pipe encasements exposed on t...

Objective: In this article, we outline the important features of pancreatic cancer surgery in cases with visceral artery encasement.

Purpose To evaluate preoperative magnetic resonance imaging (MRI) criteria for their ability to predict the complete removal of parasellar pituitary macroadenoma on the 3-month postoperative MRI. Methods Dedicated pre- and postoperative pituitary MRI studies were reviewed in 49 patients who had undergone transsphenoidal surgery for macroadenomas with potential unilateral parasellar involvement....

OBJECTIVE Cerebral vasospasm can occur after skull base tumor removal. Few studies concentrated on the posterior circulation vasospasm after tumor resection in the posterior fossa. We aimed to identify the risk factors associated with postoperative vertebrobasilar vasospasm after tumor resection in the foramen magnum. METHODS We retrospectively reviewed the data of 62 patients with tumors in ...

The physical properties and chemical composition of microsomal membranes were examined during a 7 day period of ice encasement in crown tissue of winter wheat (Triicum aestivum L. cv Norstar). Membrane damage, detected as an increase in microviscosity and electrolyte leakage, began between 1 and 3 days of icing, and was associated with a reduction in the recovery of microsomal membranes from st...

Anterior cerebral artery (ACA) encasement is often considered a contraindication for an endonasal endoscopic transsphenoidal approach. We report a patient with a tuberculum sella meningioma with ACA encasement, in whom a gross total excision was achieved through an endonasal endoscopic transsphenoidal transtuberculum, transplanum approach. The tumor was sharply dissected along the left ACA usin...
