At the same time, during TUR-P, an entrance of liquid occurs into the system that is proportional to the liquid used, the hydrostatic pressure of the solution, the number of opened venous sinuses, the time of the irrigation, the absorption speed, and amount of irrigation liquid [ 8].
Depth of myometrial penetration - when tissue damage extends into the deeper myometrium, instilled fluid can be rapidly absorbed through opened myometrial venous sinuses.
Although laparoscopic cholecystectomy appears to be less traumatic to the patients than open surgery, decreased venous return from lower extremities and hypercoagulability occurring in patients undergoing elective laparoscopic cholecystectomy with CO2 pneumoperitoneum makes it a potent risk factor for deep venous thrombosis.
When satisfactory hypothermia is achieved (depending on the institution's guidelines), the arterial line is clamped to engage into circulatory arrest, the superior vena cava (SVC) is snared, and the shunt-line is opened to achieve venous cerebral perfusion, in a retrograde fashion.
d Cerebral angiography, selective injection of the right external carotid artery: dural AV fistula of the right tentorium, fed by the right middle meningeal artery (open arrow), with early venous drainage into the tentorial and temporal veins (arrows).
Within the red pulp, blood is received by the penicillar arterioles, which open directly into the venous sinuses and trabecular vein.
In the home-care setting, patients with open wounds or central venous catheters may undertake activities of daily living (e.g., bathing, exercising, gardening, and playing with pets) that may increase the risk of infections.
Arterial phase (c) demonstrates initial patchy enhancement (arrow) followed by progressive filling of the lesion in the venous phase (d) Open image in new window Fig. 7 60-year-old man with left orbital cavernous hemangioma.
The diagnosis should be considered especially in front of open head injuries extended to venous sinuses.
