Introduction to Clip Ligation

METHODS The authors queried their institution's aneurysm database for records of consecutive patients treated for ACoA aneurysms via microsurgical clip ligation.

Venous interruption through surgical clip ligation is the gold standard treatment for ethmoidal dural arteriovenous fistula (e-dAVF).

As clip ligation techniques were refi ned, the fi eld of angiography began to blossom with Moniz, who performed the fi rst angiogram in 1927 and then later, in 1933, reported angiographic localization of a ruptured aneurysm.

While prognosis of microsurgical clip ligation is excellent, iatrogenic afferent pupillary defect secondary to mechanical compression of the optic nerve by the clips is a known complication.

Rather than the traditional bicoronal craniotomy, an endoscope-assisted mini-pterional approach for clip ligation is demonstrated.

In the first surgical stage, we performed a mastoidectomy with the infralabyrinthine approach to perform a test clip ligation of the sigmoid sinus and to resect the tumor component that extended into the infralabyrinthine space.

BACKGROUND Endovascular treated cerebral aneurysms have a greater recurrence rate compared with microsurgical clip ligation.

He underwent a sitting supracerebellar approach with a torcular craniotomy for successful clip ligation of the dural arteriovenous fistula.

The patient underwent successful definitive clip ligation of the fistula, which was exposed through a lateral suboccipital craniotomy.

OBJECTIVEIncidence rates of de novo aneurysm formation and recurrence after clip ligation remain controversial.

They have a high mortality rate when ruptured, and though endovascular techniques have emerged to tackle this, surgical clip ligation remains the preferred modality for some aneurysms.

The aneurysm was treated utilizing a bifrontal craniotomy with interhemispheric microdissection, clip ligation and resection of the aneurysm dome for pathological analysis, which ruled out a mycotic etiology.

This study was aimed to compare our results of clip ligation and en-bloc stapling of the splenic hilum.

To assess the feasibility and safety and present a case series of transradial intraoperative angiography (IOA) during microsurgical clip ligation of intracranial aneurysms.

This chapter describes the surgical procedure for right/left/bilateral Type B postaxial polydactyly excision as performed by the following approaches: suture ligation, vascular clip ligation, and instrumented excision.

Following angiography with consideration for embolization, the patient was taken to the operating room for microsurgical clip ligation with the use of minimally invasive techniques.

Microsurgery and clip ligation can be challenging in CIAs because it is very difficult to have a panoramic view of the aneurysm, where sometimes the parent vessel is laid beneath the aneurysm, difficult to identify all branches and perforators, and also the surgical corridor could be very deep and narrow and surrounded by important neurovascular structures.

Materials and methods We obtained clinical records and billing information for 141 basilar tip aneurysms treated with clip ligation (n=48) or endovascular embolization (n=93).

Finally, this longest clinical and angiographic follow-up in the literature demonstrates that clip ligation has excellent durability in GIAs, also.

Using the zygomatic anterior temporal approach, it is possible to both acquire a wide retro-carotid space and perform safety clip ligation of high-position upper basilar aneurysms without orbiotomy.
