Successful microsurgery begins with a bloodless, well-organized field.

This chapter dives into the strategies behind operative hemostasis — from early tumor devascularization and careful use of surgical corridors to precision with bipolar coagulation, irrigation, and mechanical or chemical hemostatic tools. Protecting the brain, preserving vessels, and maintaining an uninterrupted workflow are critical to efficiency and patient safety.

Master the principles that keep your field clear and your microsurgery precise at The Neurosurgical Atlas.

In this operative video, Dr. Cohen demonstrates the suboccipital approach for clip ligation of a complex medial PICA aneurysm.

Intraoperative Doppler confirms patency of PICA, though fluorescein angiography initially demonstrates residual filling of the aneurysm. A longer straight fenestrated clip is advanced to better control the distal neck, followed by placement of a curved clip that preserves the origin of PICA through the fenestration. Subsequent ICG angiography confirms complete aneurysm exclusion with maintained PICA patency. Final inspection demonstrates a healthy cerebellum, and postoperative angiography confirms patency of the vertebral artery and PICA without residual aneurysm or ischemia.

Craniotomy isn’t just about making cuts — it’s about respecting anatomy and precision.

When elevating the bone flap, wide, controlled turns of the footplate reduce the risk of dural tears. Keep the drill tangential to the skull’s inner surface and perpendicular to the bone for smooth advancement. Pause and reassess if resistance is met — forcing the drill can transmit vibrations to the brain and compromise safety.

The operating room is more than a space — it’s a strategy.

From patient positioning and team coordination to microscope balance and instrument flow, OR setup defines efficiency, safety, and surgical performance. The pathology dictates the plan, and preparation determines the outcome.

In this operative video, Dr. Cohen demonstrates the retromastoid approach for resection of a middle cerebellar peduncle metastasis.

The tumor was initially debulked using pituitary rongeurs, though it was firm and moderately vascular. After partial debulking, the lesion was circumferentially disconnected from the surrounding white matter and mobilized anteriorly and laterally, with countertraction applied using suction. The tumor demonstrated good margins consistent with a metastatic lesion and was removed piecemeal, including extraction of a larger fragment. Hemostasis was achieved, and the resection cavity was inspected, demonstrating the pons, fifth cranial nerve, and seventh and eighth cranial nerve complex.

In this operative video, Dr. Cohen demonstrates the frontotemporal approach for resection of a cavernous sinus meningioma.

The tumor is entered along its inferior aspect at the floor of the middle fossa and aggressively debulked using a pituitary rongeur due to its fibrous consistency. Dissection proceeds circumferentially along the lateral wall of the cavernous sinus, identifying and preserving the trigeminal nerve branches. Additional incisions in the lateral wall are required to further expose and debulk the tumor, with resection continuing until venous bleeding from the cavernous sinus is encountered.

In this operative video, Dr. Cohen demonstrates the clipping of a small ophthalmic artery aneurysm following a left frontotemporal craniotomy with extradural clinoidectomy.

A Carla knife is used to open the falciform ligament, providing additional proximal exposure along the internal carotid artery. A temporary clip is tested to confirm adequate control. With the proximal and distal neck fully visualized, an angled clip is placed across the aneurysm neck, with the blades aligned parallel to the long axis of the ICA. The origin of the ophthalmic artery is carefully protected during clip closure. Fluorescein and ICG angiography confirm complete exclusion of the aneurysm and patency of the ophthalmic artery and surrounding vessels.
