Laparoscopic Anatomic S7+S8d Resection Preserving Inferior Right Hepatic Vein and S6 with Right Hepatic Vein Transection
0 Views •
2025
We present a laparoscopic technique for anatomic S7+S8d resection with right hepatic vein transection, preserving the inferior right hepatic vein and segment S6. Relying on meticulous anatomical landmarks without intraoperative ultrasound, this approach offers a precise and parenchyma-sparing option for dorsally located right-liver tumors, particularly in settings with limited advanced navigation resources.

Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Lateral canthotomy is a potentially eyesight-saving procedure when performed emergently for an orbital compartment syndrome. An orbital compartment syndrome results from a buildup of pressure behind the eye; as pressure mounts, both the optic nerve and its vascular supply are compressed, rapidly leading to nerve damage and blindness if the pressure is not quickly relieved. The medial and lateral...

The mouse complete stasis model of inferior vena cava thrombosis yields quantifiable amounts of vein wall tissue and thrombus. It has proven useful for evaluating interactions between the vein wall and the occlusive thrombus and in assessing the progression from acute to chronic inflammation.

The electrolytic induction of endothelial activation to the internal surface of the Inferior Vena Cava results in venous type thrombus formation due to endothelial activation and partial blood stasis, two components of Virchow's triad.
FAQs
The obstruction creates a pressure increase in veins below the affected segment, making it harder for blood to return to the heart. Blood may then be redirected through collateral veins, which are alternative venous pathways. This compensatory route can partially preserve circulation, but persistent pressure elevation may still produce swelling, abdominal venous congestion, or impaired drainage from affected organs.
Thrombosis, external compression, and an underlying disease represent important causal categories. Distinguishing among them matters because the blockage may arise from an intravascular process or from pressure applied outside the vessel. Identifying the cause helps clinicians interpret the overall clinical picture and select management directed at the obstruction or the disease responsible for it.
Leg swelling, abdominal venous congestion, and impaired organ drainage can signal that venous outflow has been disrupted. These findings reflect pressure accumulating below the obstruction or inadequate return through normal pathways. Their presence gives clinicians a reason to investigate venous circulation and compare the symptoms with relevant imaging findings rather than treating them as isolated abnormalities.
Recognition depends on relating clinical symptoms to imaging findings. Symptoms may indicate increased venous pressure or poor drainage, while imaging can help show the obstructed or severely narrowed venous pathway and possible collateral circulation. This combined assessment supports identification of the condition, evaluation of contributing causes, and selection of an appropriate treatment strategy.
Management may include anticoagulation, endovascular recanalization, or treatment of an underlying disease. Anticoagulation addresses a clot-related component when relevant, whereas recanalization aims to reopen the affected venous pathway. Addressing the underlying disease targets the cause itself. The choice depends on the clinical and imaging context rather than on the obstruction alone.
Managing the underlying disease can be essential because external compression or another disease process may continue to compromise venous flow even after immediate symptoms are addressed. Treatment directed only at circulation may therefore be incomplete. Considering the cause alongside venous findings helps clinicians develop a plan aimed at relieving obstruction and reducing ongoing impairment of drainage.
