Spinal cord ischemia after treatment of thoracic pathologies remains a devastating problem. A 74-year-old man with a history of infrarenal abdominal aortic aneurysm repair presented with bilateral common iliac and left femoral aneurysms as well as a thoracic aortic aneurysm. He underwent an open repair of the iliac and femoral aneurysms, followed by thoracic endovascular aneurysm repair in a staged manner without complications. Ten months later, he presented with hypotension, and permanent paraplegia developed.

We report a rare complication of acute onset paraplegia after repair of an abdominal aortic aneurysm in a patient with acute type B aortic dissection. A 53-year-old man, suffering from abdominal aortic aneurysm (AAA), was admitted to our hospital with type IIIB acute aortic dissection. Ten days after admission, emergency Y-grafting was performed for impending rupture of the AAA. Twenty hours after Y-grafting, weakness of his lower extremities developed and progressed to paraplegia. Enhanced computed tomography scan revealed expansion of a thrombosed false lumen at the thoracoabdominal aorta, resulting in complete obstruction of the true lumen below the infra-renal aorta. Immediate axillobifemoral bypass was performed to prevent lower limb ischemia. Voluntary movement recovered gradually in both legs and eventually the patient could walk independently.

This report presents an extremely rare case of paraplegia following emergency surgery for a nonruptured symptomatic abdominal aortic aneurysm. A 62-year-old man underwent an emergency surgical repair for a symptomatic nonruptured infrarenal abdominal aortic aneurysm. On postoperative day 2 paraplegia following spinal cord ischemia occurred at the T8 level. The site of the ischemia was situated too high for clamping to have caused this condition, unless the patient had a congenital anomaly in the blood supply to the spinal cord or it had been caused by the previously occluded great radicular artery, which was maintained by the collateral blood supply from the iliac circulation.

Spinal "stroke" is an uncommon cause of paraplegia. Spinal cord infarction from unruptured aortic aneurysm is rare. When encountered it poses diagnostic challenge to the clinician due to its rarity, which may lead to incorrect or delayed diagnosis. We report a case of 62-year-old man presenting to casualty as caudaequina syndrome due to spinal cord infarction secondary to emboli from an infra renal abdominal aortic aneurysm. To the authors knowledge this is first case of its kind and has not been reported in literature. Patient had improvement in proximal motor function following repair of the aneurysm, although he remained doubly incontinent in six months follow up.

Endografting, like open surgical repair of the thoracic aorta, can be complicated by paraplegia. We reviewed our thoracic endografting experience regarding the incidence and treatment of spinal cord neurologic events. Between February 2000 and July 2008, 346 patients underwent endoluminal grafting of the descending thoracic aorta. Indications for intervention included atherosclerotic aneurysms (45.9%), acute and chronic dissections (31.5%), miscellaneous lesions (13.6%), and penetrating aortic ulcers (8.9%). Ten women and 4 men (4.0%), with a mean age of 71.3 years, developed either paraparesis (1.7%) or paraplegia (2.3%). Nine (64.3%) of these patients had an aneurysm, 4 (28.6%) had acute or chronic type B aortic dissection, and 1 (7.1%) had a penetrating aortic ulcer; 3 (21.4%) of them had previously undergone open abdominal aortic aneurysm repair, and 13 (92.9%) required coverage of more than 20 cm of the aorta. Cerebrospinal fluid drainage was instituted in 7/8 paraplegic patients. Eight (57.1%) of the 14 patients recovered fully, 2 (14.3%) experienced partial recovery, and 4 (28.6%) had significant neurological deficits. Paraplegia following thoracic endografting appears to be associated with female sex, long-segment coverage of the thoracic aorta, and aneurysmal disease.

Spinal cord ischemia is a rare complication after abdominal aortic surgery and has been attributed to surgical devascularization of the spinal cord, atheroembolization of the cord circulation, or hypoperfusion of cord structures secondary to hypotension or cord edema. We present a diabetic, hypertensive 75-year-old male with endstage renal disease who presented with a 5.5 cm asymptomatic infrarenal abdominal aortic aneurysm, and concomitant 3.5 cm right common iliac artery aneurysm. After undergoing successful endovascular repair with an aorto-uni-iliac device, unilateral hypogastric artery embolization, and femoral-femoral bypass, he was discharged to a rehabilitation facility neurologically intact with a stage 2 decubitus ulcer. He returned on postoperative day 21 with a large stage 4 septic decubitus ulcer, fever, leukocytosis, hypotension, and paraplegia. We hypothesize that the compromised blood flow from the initial reconstruction, combined with the delayed hypotension imposed by sepsis, resulted in spinal cord infarction. He was eventually discharged to a nursing facility with no improvement in his neurologic status. We report the first case of significantly delayed permanent paraplegia after endovascular abdominal aortic aneurysmorrhaphy.

Open thoraco-abdominal aortic aneurysm repair is a demanding procedure with high impact on the patient and the operating team. Results from expert centres show mortality rates between 3-21%, with extensive morbidity including renal failure and paraplegia. Endovascular repair of abdominal aortic aneurysms initially required an undilated portion of the aorta below the renal arteries to safely fixate the stent-graft. More complex abdominal artic aneurysms (i.e., short-necked, juxta- and suprarenal aneurysms) were later successfully treated with fenestrated grafts. The development of branched grafts opened the way to treat thoraco-abdominal aneurysms endovascularly. In this review, a comprehensive overview of technical aspects and results of the available literature is given. Mortality rates are below 10%, with spinal cord ischemia reported between 2.7% and 20%. Target vessel branch patency invariably has been reported between 95% and 100%, with first mid-term results demonstrating evidence for durability. Most series included high-risk patients, who were denied open repair. Nevertheless, risks associated with endovascular repair of thoraco-abdominal aneurysm should be acknowledged. Technique-specific complications including perforation of small vessels due to multiple catheterization resulting in retroperitoneal hematoma, and compartment syndrome of the lower limbs should be mentioned. Technical evolution of branched grafts is ongoing. Tapering down the main graft to allow for room for the branches has resulted in easier catheterization of target vessels and insertion of bridging stent-grafts. For the same reason, the branches for celiac artery and superior mesenteric artery are deliberately off-set in position. To stabilise the usually long devices, additional spiral wires have been added, to facilitate deployment in the correct orientation. Endovascular repair of thoraco-abdominal aneurysms will continue to evolve and gradually take over from open repair, in view of the much lower physical impact on the patient.

Thrombosis of an abdominal aortic aneurysm is a rare devastating complication with an estimated mortality rate of 50%. Simultaneous acute pain, pallor and coldness of the lower limbs, mottling from the level of iliac crests or umbilicus, paraplegia and absence of femoral pulses are all manifestations of a sudden and acute interruption of blood flow through the aneurysmatic aorta. We report a case of an occlusion of an abdominal aortic aneurysm during hospitalization which was not manifested with symptoms of limb ischemia. In this case we feature the rare and unusually "silent" presentation of the event.

A 66-year-old man with multiple comorbidities presented with a juxtarenal perianastomotic aortic aneurysm 10 years after open abdominal aortic aneurysm repair. The aneurysmal disease also involved both iliac bifurcations, the right internal iliac artery, the left common femoral artery (CFA) up to its bifurcation, and the homolateral popliteal artery. We performed bilateral internal iliac artery coil embolization 1-month apart. Later, we performed aortouniiliac endografting extending to the right external iliac artery and placement of an endovascular plug in the left external iliac artery. A right CFA to left femoral bifurcation bypass graft was then constructed after ligation of the left CFA aneurysm. After recovering from anesthesia and despite sequential hypogastric embolization, the patient developed postoperative paraplegia, buttock ischemia, and ischemic colitis and died on postoperative day 5. The possible pathogenic mechanisms involved in the onset of these ischemic complications are discussed in this article.

In patients with previous infrarenal abdominal aortic aneurysm (AAA) repair, the risk of spinal cord ischemia increases after thoracic endovascular aortic repair (TEVAR) for a descending thoracic aortic aneurysm (DTAA). The case is a 67-year-old man with a 60 mm infrarenal AAA and a 73 mm DTAA. We performed the staged hybrid procedure for these aortic aneurysms. First of all we underwent a conventional AAA repair. The bilateral internal iliac arteries and a inferior mesenteric artery were preserved. In addition, the right leg of the tube graft was anastomosed to the right superficial femoral artery to facilitate access of TEVAR. Two months later we performed TEVAR for the DTAA. DTAA extended from the level of the 7th thoracic vertebra to that of the 11th thoracic vertebra. Although there was a certain risk of paraplegia, no complications occurred. The hybrid procedure for combined DTAA and AAA may be a valuable option.
