Bilateral occlusion of common iliac artery following anterior retroperitoneal approach for lumbar fracture instrumentation

There are only four reports on unilateral occlusion of the common iliac artery following ipsilateral anterior retroperitoneal approach to the lumbar spine. To the authors' knowledge, there are no previous reports on delayed bilateral iliac artery occlusion following retroperitoneal approach. We report on a rare case of a 37-year-old paraplegic man who sought this department with bilateral iliac artery occlusion and simultaneous unilateral thromboembolism to the left popliteal artery. The problem occurred following retroperitoneal approach for instrumentation of an L2 fracture performed 2 years ago. The left leg was amputated above the knee because of gangrene, while a left-sided abdominal-to-femoral artery bypass was performed to salvage the right leg. Six months later, the right leg was amputated below the knee because the patient was admitted again with gangrene of his right foot. Following that, the loosened anterior hardware was removed via a right retroperitoneal approach. Revision surgery revealed an apposition of the common iliac vessels from the loosened hardware, while the vertebral bodies at the affected area were severely osteoporotic. Spine surgeons should be aware for the appearance of this disastrous complication following anterior retroperitoneal surgery in patients with loss of sensation in the lower extremities who do not present subjective symptoms of ischemia. The presence of hardware loosening and migration, loss of correction and pseudarthrosis are the warning signs for diagnosis of such a complication.

     

The open anterior paramedian retroperitoneal approach for spine procedures

HYPOTHESIS: With the advent of anterior lumbar interbody fusion and artificial disk replacement as common procedures for the treatment of many spinal problems, anterior exposure has become an increasingly popular procedure for general, thoracic, urologic, and vascular surgeons. Despite this, the body of literature describing this procedure, especially the general and vascular surgery literature, is lacking. DESIGN: A retrospective review of medical records was performed for patients operated on from April 2002 to March 2004. SETTING: Tertiary care university hospital. PATIENTS: In total, 64 open retroperitoneal exposures for anterior spinal approaches were performed. Thirty-five (55%) were performed on men and 29 (45%) on women. INTERVENTIONS: Fifty patients (78%) required lumbosacral approaches, and 14 (22%) required access to purely lumbar disk spaces. Forty-three patients underwent single-disk approaches, and 21 required access to either 2 or 3 levels. Forty patients (63%) underwent anterior lumbar interbody fusion, and 22 (34%) had a Prodisc disk replacement. MAIN OUTCOME MEASURES: We analyzed intraoperative and early postoperative complications. RESULTS: The average age was 43 years (range, 25-89 years), 42 and 44 years for men and women, respectively. Ninety-seven percent of all attempted retroperitoneal exposures were successful. Intraoperative complications occurred in 5 patients (8%) and included inability to mobilize the iliac veins, injury to the iliac vein, and ureteral tear. The postoperative course was complicated in 8 patients (14%) and included fever, urinary retention, spinal headache, Clostridium difficile colitis, and ileus. CONCLUSION: Open retroperitoneal exposure to the lumbar and lumbosacral vertebral bodies can be performed safely with a multidisciplinary approach that maximizes the various surgical skills of the orthopedic and vascular or general surgeon, reducing complication rates in anterior spinal surgery.     

Posterior approach for retroperitoneal laparoscopic bilateral nephrectomy in a child

We report on a unique posterior approach for bilateral nephrectomy by retroperitoneoscopy that was conducted in a 13-year-old boy with end-stage renal disease managed by peritoneal dialysis. A posterior approach for bilateral nephrectomy by retroperitoneal laparoscopy provided adequate visualization and created enough working space for the manipulation. The procedure was performed during a short period, and the patient did not need to be repositioned. Retroperitoneal laparoscopic bilateral nephrectomy is a useful option in school-aged children with poorly functioning kidneys, particularly those children also undergoing peritoneal dialysis.     

Traumatic aneurysm of the abdominal aorta with acute thrombosis of bilateral iliac arteries

A traumatic aneurysm of the abdominal aorta resulting in acute peripheral thrombosis is rare. A 29-year-old man suffered a sudden occlusion of the terminal abdominal aorta and bilateral iliac arteries. An infrarenal abdominal aortic aneurysm was found, along with destruction of lumbar vertebrae and an aberrant renal artery. The pathogenesis of this false aneurysm was thought to be traumatic rather than inflammatory because the patient's history and laboratory findings showed no signs of inflammatory reactions. He had been in an automobile accident five years previously, resulting in lumbar vertebral injury. Arterial reconstruction and intraoperative perfusion of the aberrant renal artery were performed successfully. To our knowledge, our case is the seventh one reported in the English literature of a traumatic aneurysm of the abdominal aorta successfully repaired by surgery.     

Single osteotomized iliac crest free flap in anterior mandible reconstruction

While the iliac crest flap provides a natural contour for the lateral segment of the mandible, for the anterior segment en bloc, the use of the iliac graft, even harvested in a V shape, fails to yield a three-dimensional natural-shaped reconstruction. In this report, we present our experience with reconstruction of the anterior segment of the mandible using a single osteotomized free iliac crest flap in 5 patients. The study comprised 4 male patients and 1 female patient, their ages ranging between 34-82 years. In all patients, composite iliac osteomusculocutaneous flaps were harvested based on the deep circumflex iliac artery in the standard manner, and the bony segment of the flap was divided into two segments, performing a single osteotomy. The fixation of bone segments was performed in new positions, sliding the segments in different planes to provide the original shape of the resected mandible segment, and in a manner appropriate to the defect. The overall flap success rate was 100%. In no cases were wound infections or hematomas observed. X-rays showed bone healing without resorption. In conclusion, the use of a single osteotomy for an iliac crest flap in the reconstruction of the anterior segment of the mandible is a simple and safe procedure, and provides a natural and acceptable jaw appearance. The risk of devascularization is quite low when compared with the multiple osteotomy procedure, and it does not need to be fixed with complex devices such as reconstruction plates or external fixators.

Midline extraperitoneal approach for bilateral widespread retroperitoneal abscess originating from anorectal infection

IntroductionAnorectal abscess is one of the most common anorectal conditions encountered in practice. However, such abscesses may rarely extend upward and cause life-threatening medical conditions.Presentation of caseA 53-year-old woman presented with symptoms of anorectal abscess and evidence of severe inflammatory response and acute kidney injury. Computed tomography revealed a widespread abscess extending to the bilateral retroperitoneal spaces. Surgical drainage was performed via a totally extraperitoneal approach through a lower midline abdominal incision, and the patient had a rapid and uncomplicated recovery.DiscussionAlthough retroperitoneal abscesses originating from the anorectal region are rare, they are life-threating events that require immediate treatment. Percutaneous abscess drainage has been recently evolved; however, surgical drainage is required sometimes that may be challenging, particularly in the case of widespread abscesses, as in our case.ConclusionThe midline extraperitoneal approach reported here might be an effective surgical option for patients with bilateral widespread retroperitoneal abscesses.     

Using bilateral iliac branch devices for endovascular iliac aneurysm repair

Introduction: The endovascular repair of bilateral iliac aneurysms using bilateral Iliac Branch Devices (IBDs) has been infrequently performed and reported. We aim to describe this technique and report on the results of our case series. Methods: Three different device designs are available. The procedural options include a totally transfemoral approach, or a combined transfemoral and brachial approach. Clinical records for patients who have had this procedure were reviewed. Results: The indications for the technique include bilateral common iliac artery aneurysm repair, with or without concomitant abdominal aortic aneurysm repair. Considerations include the timing of main body endovascular aortic aneurysm repair (EVAR) device introduction, the use of a proximal access site and the type of IIA stent‐graft that is used. Between 2007 and 2010, six patients had bilateral IBD implantation. All patients required an EVAR main body device in addition to bilateral IBDs. Eighty‐three per cent were males, mean age was 73 years. Mean follow up was 15 months. Technical success was obtained in 100% of cases. There was one branch occlusion (8.3%). There were no type I endoleaks. One patient had a type II endoleak. Conclusions: Bilateral IBDs can be used safely and with excellent rates of technical success and branch patency in appropriately selected patients.     

Alternative management of iliac vein injury during anterior lumbar spine exposure

Vascular injuries are, unfortunately, common complications during anterior approach to lumbar spine, with venous injuries occurring most frequently. The L4-L5 level of exposure is associated most commonly with venous injuries because it requires significant mobilization of the vascular structures. We present two cases of left common iliac vein tears encountered during redo anterior exposure for spine revision. This was in the setting of an anterior lumbar interbody fusion at the L4-L5 level and for the repeat disc arthroplasty at the L5-S1 level. We describe the endovascular technique used to successfully repair venous tear with the deployment of a covered stent across the injury, preventing the ligation of the left common iliac vein.
