BACKGROUND AND PURPOSE The inferior petrosal sinus (IPS) is the main transvenous access route used to examine or treat lesions involving the cavernous sinus. To carry out these procedures successfully, one must have a detailed knowledge of the anatomy of the venous system around the junction of the IPS and the internal jugular vein (IJV). MATERIALS AND METHODS Eighty-three sides in 63 patient...

INTRODUCTION The prophylactic use of closed suction drains after retroperitoneal lymphadenectomy in the management of gynecologic tumors has been widely used to prevent collections of clots or lymph and to avoid infections and postoperative fistulas. The improvement of newer surgical techniques, the use of antibiotic prophylaxis, and the nonclosure of the peritoneum led to the need to reevaluat...

Abstract: In recent years deadly earthquakes in seismic areas have caused special concerns regarding liquefaction phenomenon by researchers and specialists. Excess pore water pressure in loose sediments may cause phenomena such as boiling, shearing strength and dynamic stiffness reduction and lateral movements cause difficulties. Many remedial methods such as soil replacement with proper materi...

* Department of Surgery, College of Medicine, Hawler Medical University, Erbil, Iraq. Introduction Traditionally many surgeons advocate draining the neck routinely after thyroid surgery. Although several prospective randomized reports regarding the function of the drains in thyroid surgery have not justified their use, most surgeons still employ routine drainage of the thyroidectomy bed. The ma...

mathematical simulation of flow toward drains is an important and indispensable stage in drainage design and management. many related models have been developed, but most of them simulate the saturated flow toward drains without a due consideration of the unsaturated zone. in this study, the two dimensional differential equation governing saturated and unsaturated flow in porous media is numeri...

INTRODUCTION Controversy still surrounds the use of drains after total knee replacement (TKR). We compared closed suction drains, reinfusion drains and no drains by studying haemoglobin (Hb) levels, blood transfusion requirements and functional knee outcome scores in a single surgeon series. METHODS A total of 102 consecutive primary TKRs were performed by the senior author between September ...

OBJECTIVE To determine whether bacterial colonization of drains can be reduced by local antiseptic interventions. BACKGROUND Drains are a potential source of bacterial entry into surgical wounds and may contribute to surgical site infection after breast surgery. METHODS After institutional review board approval, patients undergoing total mastectomy and/or axillary lymph node dissection were...

BACKGROUND AND AIMS There is no consensus among surgeons on the indication of putting drains for in groin hernias. In this study we aimed to investigate the factors that are associated with drain usage by comparing the clinical characteristics of patients who had drains with the patients without drains in the repair of groin hernias. MATERIAL AND METHODS The data of all groin hernia repairs f...
