Leriche syndrome. Surgical procedures and early and late results

Sacral Pressure Ulcer in Leriche Syndrome: A Case Report

We experienced a case of a sacral pressure ulcer complicated with Leriche syndrome, an aortoiliac artery occlusion that has not been previously reported. In this case, the abdominal aorta below the bifurcation of the renal arteries into the bilateral common iliac arteries was occluded, and wound healing was delayed. Therefore, endovascular treatment was used for managing this condition, and wound healing was accelerated. Then, reconstructive surgery with a local flap was performed, and wound healing was achieved. In the case of delayed healing of buttock pressure ulcers, it is important to evaluate the blood flow in the iliac artery as well as the infection and nutritional status of the wound. In addition, after endovascular treatment, blood flow in the local flap is a matter of concern. If the wound healing is good, and imaging confirms that there is no restenosis at the endovascular treatment site and the perforator of the flap, reconstructive surgery can be performed safely.

Balloon occlusion of the contralateral iliac artery to assist recanalization of the ipsilateral iliac artery in total aortoiliac occlusion: a technical note

Endovascular recanalization of chronic total aortoiliac occlusion is technically challenging. Inability to reenter the true aortic lumen, following retrograde iliac recanalization, is one of the most common causes of failure. We describe a case of a total aortoiliac occlusion where balloon occlusion of the right common iliac artery, following its recanalization from a brachial approach, was used to facilitate antegrade recanalization of the occluded contralateral left common iliac artery.

Endovascular management of chronic infrarenal aortic occlusion

PURPOSE

To review our experience with the endovascular treatment of chronic infrarenal aortic occlusion with regard to technical success and midterm patency, as well as perioperative mortality and morbidity.

METHODS

A retrospective review was performed of patients who presented from January 1, 2000, to December 31, 2005, with a diagnosis of chronic infrarenal aortic occlusion (TASC D) treated with endovascular techniques. In this time period, 31 patients (22 women; mean age 63 years) underwent attempted recanalization of the occluded aorta and iliac arteries. Claudication was the most common presenting symptom (14, 45%). Patients were treated solely with angioplasty and stenting or thrombolysis followed by angioplasty/stenting based on surgeon preference.

RESULTS

Technical success was 93%. The 2 failures were individual cases of wire-induced iliac artery perforation and failed access; both patients were treated with bypass grafting. Nine (29%) patients had thrombolysis prior to angioplasty. There were no perioperative deaths. Postoperative ankle-brachial indexes increased significantly from preoperative values (p<0.0001). There were 3 technical complications: 1 (3%) iatrogenic iliac artery injury and 2 (6%) perioperative limb thromboses requiring intervention. Other complications included 6 (19%) access site events and 5 (16%) episodes of acute renal dysfunction, 2 requiring permanent dialysis. Over a mean follow-up of 12 months, there was no limb loss. At 1 and 3 years, the primary/secondary patency rates were 85%/100% and 66%/90%, respectively.

CONCLUSION

Endovascular therapy for chronic infrarenal aortic occlusion has a high technical success rate, with good midterm primary and secondary patency rates. However, renal dysfunction can occur; the etiology is likely multifactorial from contrast volumes, embolization, and/or renal arterial disease.

Hybrid treatment for juxtarenal aortic occlusion: Successful revascularization using iliofemoral semiclosed endarterectomy and kissing-stents technique

A 53-year-old man with a significant respiratory history waiting for lung transplantation presented with severe bilateral buttock and thigh claudication. Angiography revealed severe stenosis of the left renal artery and total occlusion of the infrarenal abdominal aorta and iliac vessels. Via a bilateral surgical femoral exposure, we performed semiclosed endarterectomy of the iliofemoral vessels and percutaneous transluminal angioplasty stenting of the infrarenal aorta with two Palmaz stents and percutaneous transluminal angioplasty "kissing stents" of the iliac arteries with three Luminexx stents bilaterally. Completion angiography showed successful complete recanalization of the aortoiliofemoral axis. Palpable distal pulses were restored. A combined surgical and endovascular approach should be considered a viable alternative to laparotomy in selected patients with total juxtarenal aortic occlusion.

Radical hysterectomy for IB cervical cancer in a patient with aorto-femoral transposition

We present a cervical cancer case in stage IB, according to FIGO classification, treated with radical hysterectomy and pelvic lymphadenectomy. The 48-year-old patient had 4 years previously undergone a Y aorto-bifemoral Dallon transposition as a result of Leriche's syndrome. During the routine investigation invasive cervical cancer was diagnosed. She had radical hysterectomy of Piver III type and partial pelvic lymphadectomy. Radical hysterectomy caused no technical trouble. Pelvic lymphadenectomy was only partially possible because of hard connective tissue around the artificial vessels. This scarred region made safe preparation of the total pelvic lymphatic system impossible.
