Endovascular Aortic Repair Complications and the Power of Endovascular Solutions.

We report the case of a 75-year-old man submitted to traditional endovascular aortic repair (EVAR) for infrarenal abdominal aortic aneurysm. He presented a late type II endoleak 6 months after operation, initially without sac enlargement. One year later, a computed tomography scan control demonstrated a sac expansion >10 mm, also responsible for a secondary proximal type I endoleak. The patient was submitted to transarterial embolization of lumbar arteries through left internal iliac artery, followed by type I endoleak correction with a proximal cuff deployment. Intraoperative angiography revealed no signs of endoleak. Six months later, a sudden enlargement of the sac was detected, with evidence of type III endoleak, probably consequence of the lumbar arteries embolization, promptly corrected through an aortoaortic endograft. In conclusion, even if a conservative approach for type II endoleak without sac enlargement is proposed, sometimes a sudden sac enlargement could be responsible for catastrophic events in the absence of strict follow-up. The sac embolization during EVAR could reduce the incidence of type II endoleak during follow-up, with reoperation and hospital cost reduction.

Endovascular and open surgical treatment of complications after endovascular aortic aneurysm repair: A single-center experience.

While endovascular aortic aneurysm repair (EVAR) has proven to be a safer alternative to open surgical repair for infrarenal abdominal aortic aneurysms (AAA) repair, the development of stent-graft complications mandates follow-up computed tomography imaging to minimize AAA-related mortality. In this single-institution report, adverse EVAR events identified in 150 consecutive patients are detailed. Early morbidity was low (<3%), with only 1 patient death on post-procedure day 2. After discharge (mean follow-up of 24 months), 2 patients died from cancer and one AAA-related mortality occurred after open conversion for stent-graft migration. Although computed tomography imaging detected no EVAR endoleak at 30 days, 19 patients developed an endoleak, including three Type I and four Type III leaks. Our institutional series review confirmed that EVAR of infrarenal AAA is a safe and valid alternative to open surgical repair, but sac embolization at the primary procedure in patients judged to be at high risk for Type II endoleak should be considered.

Unstable atherosclerotic plaque in the common carotid artery: Diagnosis and treatment strategy.

The indication for carotid artery stenosis treatment is based primarily on the severity of internal carotid stenosis. There is increasing evidence that unstable plaques in the extracranial carotid artery can be responsible for ischemic stroke or transient ischemic attacks as the source of emboli, even if in the presence of a moderate stenosis. Physicians should be aware that morphological characteristics of the carotid plaques that indicate recent intra-plaque hemorrhage might require intervention in the absence of severe stenosis. This report details a patient with an unstable plaque in the common carotid artery who met clinical criteria for intervention because of the risk for future stroke.

Traumatic Anterior Knee Dislocation with Popliteal Artery Injury: The Importance of a Prompt Diagnosis and Treatment to Obtain Lower Limb Salvage.

We report a case of traumatic anterior dislocation of the left knee in association with disruption of the soft tissues including knee ligaments, popliteal artery, and common peroneal nerve, resulting in lower limb acute ischemia. All components of this complex trauma were recognized and treated promptly. First, he was submitted to closed reduction of the dislocated knee under general anesthesia; right after he underwent superficial femoro-tibioperoneal trunk bypass using a reversed saphenous contralateral vein recurring to a posterior approach through a popliteal S-shaped incision; rehabilitation program was initiated early; a second and final reconstructive orthopedic operation was carried out in a different center. The present case is important in 2 aspects. First, it reports a very rare occurrence of simultaneous anterior dislocation of the knee associated with vascular insult and common peroneal nerve injury, which was rarely reported in the current literature; second, it highlights that with timely intervention and a team approach, excellent results could be achieved.

A Combination of Thoracic and Abdominal Stent-Grafts to Treat An Abdominal Aortic Aneurysm with Hostile Proximal Neck.

Endovascular aneurysm repair (EVAR) actually represents the treatment of choice for most patients affected by abdominal aortic aneurysm (AAA). However, the feasibility of EVAR depends on anatomical characteristics of abdominal aorta and iliofemoral axis. We present the case of an 82-year-old man affected by severe left hydronephrosis, kidney tumor, and ureteral tumor requiring nephrectomy, who also presented a very voluminous AAA with a large diameter (96 mm), and a large proximal neck (39 mm) with severe angulation of the proximal neck (>60°). The patient was considered unfit for traditional EVAR and open surgery. Possible alternatives such as fenestrated endovascular abdominal aortic aneurysm repair and chimney technique were excluded; therefore he was treated combining Valiant Captivia endoprosthesis with the AFX unibody, with a good final result. However, this particular alternative adopted for hostile proximal neck needs long-term follow-up.

Infrarenal Abdominal Aortic Pseudoaneurysm: Is It a Real Emergency?

Abdominal aortic pseudoaneurysm is a rare but life-threatening condition that occurs due to penetrating or blunt trauma. Clinical manifestations are variable, and the time interval from the initial trauma to diagnosis is variable. A prompt diagnosis and an aggressive management approach are required to avoid catastrophic complications. Possible treatment options are open surgical repair, endovascular repair, pseudoanerysmal sac thrombosis induction through direct thrombin injection, and coil embolization. Here, we present the case of a 75-year-old man affected by an infrarenal abdominal aortic pseudoaneurysm presenting with abdominal and lumbar pain for 3 days, who was successfully treated with an endograft.
