Background:In bypass surgery, a single-handed needle holder is usually used with other handed fine forceps. Recently, a needle holder with the function of fine forceps has been developed.

Methods:In this technical note, usefulness of newly developed needle holders in both hands is presented in bypass surgery.

Results:With this method, surgeons can make stitches and ties by both hands without exchanging instruments.

Conclusions:This method is effective and may result in faster anastomotic procedure comparing with the traditional one.


Extracranial-intracranial (EC-IC) bypass surgery such as superficial temporal artery-middle cerebral artery (STA-MCA) bypass has been widely performed for moyamoya disease, artery involved tumors, complex aneurysms, and selected ischemic stroke due to arteriosclerosis.[ 1 2 3 4 5 6 7 8 ] The success of bypass surgery depends upon meticulous technique and the use of appropriate instruments.[ 1 2 3 8 ] Usually, needle holder in dominant hand and fine forceps as holding tissue in nondominant hand have been widely used during making stitches between donor and recipient [ Figure 1a ]. Then, both-handed fine forcipes are commonly used when tying the suture. Because it is difficult to hold nylon threads using conventional needle holders [ Figure 1a ]. By contrast, fine forceps is not good for handling the needle. In this technical note, we propose the usage of both-handed needle holders with a function of fine forceps [ Figure 1b ] in EC-IC bypass.

(a) Traditional method using a needle holder in the dominant hand and a fine forceps in the nondominant hand. (b) The present method using both-handed newly developed needle holder. The present needle holder in the left hand can hold the adventitia of the vessel. (c) The tips of the present needle holder on the left are placed into the vessel lumen and the right needle holder thrusts the needle through the vessel wall between the left-sided tips which provide counter pressure. (d) Tying procedure the suture with both-handed needle holders



STA-MCA bypass is carried out in the standard manner[ 2 4 7 ] with newly developed needle holder [Figures 2 and 3 ] usage as described below. No surgical complications related to the needle holder have been observed in our experience.

A new type of needle holder having fine long jaws as acting fine forceps is recently released from Mizuho Co., Ltd., Tokyo, Japan and Muranaka Medical Instruments Co., Ltd., Osaka, Japan [Figures 2 and 3 ]. Although both needle holders have a function of fine forceps, there is a difference in the handles. A round handle is made by Mizuho and a flat handle by Muranaka [ Figure 2 ]. The present needle holders easily hold the 10-0 and 11-0 monofilament nylons [ Figure 1d ]. The tips of the present needle holder can be placed into the vessel lumen [ Figure 1c ]. If a surgeon has the present needle holders in both hands to perform bypass surgery, no exchanging of the instruments is necessary to make stitches and tie threads [ Figure 1d ]. A surgeon also makes stitches in nondominant hand.


Although several surgical techniques are available such as double insurance bypass,[ 5 ] the fingertip support technique,[ 3 ] and mattress anastomosis,[ 1 ] good micro-instruments are mandatory for accurately performing high quality bypass surgery. In this technical note, we present a new micro-needle holder in both hands that offers good handles of needle and threads.

The present needle holder allows a surgeon an excellent handling such as placing tips into the vessel lumen for counter-pressure [ Figure 1c ] when the needle is passed through the wall and lightly grasping the adventitia [ Figure 1b ] including making stitches. Since the novice neurosurgeons have difficulty to place tips into the vessel lumen and apply counter-pressure using fine forceps, they should practice to learn accurate skilled movements using fine forceps such as jeweler's forceps. In contrast to the process of learning to operate on with fine forceps, the newly developed needle holder usage can be easy to perform the appropriate bypass.

The fine forceps sometimes damage or snap monofilament nylons during tying threads because the tips of forceps are too sharp and hold nylons in a pin-point manner. By contrast, the present smooth needle folder jaw with rounded edges rarely damage monofilament sutures. This is also an advantage of a both-handed needle holder technique.

In our experience, only the present needle holder usage without fine forceps is difficult in very small recipient bypass (less than 0.7 mm in size) in some patients with moyamoya disease. Therefore, such extremely fragile vessel bypass still requires the ultra-fine forceps.


This technique can facilitate faster and more efficient microsurgical anastomosis, which the novice neurosurgeon may find useful. The present needle holder in both hands might reduce the occlusion time without exchanging the instruments.
