Total Laparoscopic Iliac Artery Aneurysm Repair Using Endoscopic Techniques and Endovascular Balloon Occlusion
Article Outline
We present a novel total laparoscopic technique to treat patients with iliac and aorto iliac aneurysms. The laparoscopic procedure does not require clamping of the iliac arteries because of a hybrid approach.
Report
Laparoscopic exposure of the aorta is performed using transperitoneal left retrorenal access. A transfemorally placed balloon catheter blocks the external iliac artery. Two haemostatic sheaths are inserted directly through the skin into the abdominal cavity. Balloons are passed through these sheaths to block the common iliac artery and the hypogastric artery, allowing bypass grafting to be performed with appropriate haemostatic control.
Discussion
The technique described preserves inflow into the hypogastric arteries . This is accomplished by a combination of laparoscopic and endovascular techniques reducing the problems that can be caused by clamping diseased arteries.

Introduction
Aorto iliac and large iliac artery aneurysms can present quite a technical challenge when trying to perform a total laparoscopic repair. A combination of laparoscopic and endovascular techniques can facilitate these complex operations. In the following report we describe a simple hybrid technique for total laparoscopic repair of iliac and aorto iliac aneurysms preserving inflow into at least one hypogastric artery.
Report and Technical Details
The technique described was used in patients with iliac or aorto iliac aneurysms.
Laparoscopic access was gained by a transperitoneal left retrorenal approach after mobilization of the left hemicolon in all cases.1 If necessary to obtain better exposure the left hemicolon was suspended with two stay sutures.2 This permitted rapid exchange of the instruments in the lower abdomen without the risk of bowel injury by scissors or laparoscopic dissectors and without small bowel obstructing the view.
The hybrid laparoscopic technique used depended mainly on the morphology and anatomic distribution of one or more iliac artery aneurysms:
Technique of balloon placement
The hybrid procedure includes percutaneous transfemoral balloon insertion over the wire in patients with right common iliac artery aneurysms. A 9 F haemostatic sheath is inserted into the right common iliac artery. Intraoperative fluoroscopy is only required in cases where the Terumo wire cannot be advanced expeditiously from the groin into the aorta. For occlusion of the right external iliac artery we prefer a 8 or 9
mm angioplasty balloon catheter. Alternatively a Fogarty embolectomy catheter with an extra lumen for the guide wire can be employed. The percutaneous access of the right common femoral artery is sealed postoperativey with an occlusion device.
For transabdominal balloon catheter insertion a 9 F haemostatic sheath is inserted over the wire directly through the abdominal wall. In patients with left sided common iliac artery aneurysms two balloons are required, one to block backflow from the left external iliac artery and the second one for the left hypogastric artery. We do not use a transfemorally placed balloon catheter on the left side (Fig. 1).

If possible at least one distal anastomosis is performed laparoscopically with the iliac bifurcation (Fig. 2). In cases with hypogastric artery aneurysms coil embolization is performed transfemorally first, followed by staple occlusion of the common iliac and the proximal external iliac artery and a distal anastomosis with the external iliac artery or with the femoral artery. In cases with severe calcifications it can be easier to staple or to oversaw the aortic bifurcation minimizing the risk of venous injury.3 In calcified vessels there can be severe suture hole bleeding from the staples which can be avoided when the line of staples is reinforced with a PTFE sleeve.

In patients with bilateral aorto iliac artery aneurysms after completion of the aortic anastomosis we first perform an anastomosis with the left common iliac artery or the left iliac bifurcation because access is easier and perfusion of the limb and the pelvic circulation can be restored more rapidly.
In obese patients exposure of the right common iliac artery and the iliac bifurcation requires an additional retractor in the right lower abdomen and a more neutral rotation of the operating table (30
°).
Discussion
In our experience the use of the hybrid balloon occlusion technique was associated with less incidence of iliac artery dissection and thrombosis compared to iliac artery clamping with laparoscopic instruments. Balloon occlusion and total laparoscopic resection of iliac artery aneurysms has been performed in 19 patients. In four patients either due to adhesions in the right lower abdomen or to acute small bowel distension we had to use a small extraperitoneal suprainguinal incision to perform the anastomosis with the right iliac bifurcation. In one case we converted to a retroperitoneal incision because of bleeding from the right common iliac vein. The operating time is longer compared to a total laparoscopic tube graft repair mainly due to the complexity of the laparoscopic anastomosis with the right iliac bifurcation.
The essential operative steps can be summarized as followed: Left iliac aneurysms require a laparoscopic anastomosis with the iliac bifurcation. Right common iliac aneurysms require transabdominal and transfemoral balloon occlusion before the anastomosis with the right iliac bifurcation can be performed. In cases where the ipsilateral hypogastric artery is occluded staple occlusion of the aneurismal segment and an anastomosis with the femoral artery facilitates the procedure.
The technique described permits a total laparoscopic operation in patients with aorto iliac artery aneurysms. An anastomosis with the iliac bifurcation reduces the incidence of gluteal ischemia and buttock claudication. Endovascular repair in these cases would have required covering the origin of at least one hypogastric artery increasing the risk of bowl ischemia.4
In conclusion combining endovascular and laparoscopic techniques permits total laparoscopic aorto iliac aneurysm resection in cases which are otherwise very difficult or impossible to treat laparoscopically.
