Hybrid open and endovascular treatment of an aortic arch pseudoaneurysm in a patient with human immunodeficiency virus infection.

We describe an hybrid approach for aortic pseudoaneurysm with open and endovascular treatment as an alternative treatment for a high-risk patient infected with human immunodeficiency virus. A 42-year-old man, serum positive for human immunodeficiency virus, presented, with a large pseudoaneurysm of the arch aorta measuring 61 × 70 mm. An aortic arch debranching was performed, completed by thoracic endovascular aneurysm repair. A control computed tomography scan performed 3 months later showed a complete thrombosis of the pseudoaneurysm. The outcome of this treatment, particularly regarding the rate of infection, is yet to be determined, Longer follow-up is needed with a greater of patients.

Pseudoaneurysm of the subclavian artery following clavicle fracture due to blunt traumatism: a case report.

The clavicle fractures are frequent, vascular injuries associated with closed fractures of clavicle are rare. The pseudoaneurysms of the subclavian artery constitute an exceptional complication. We report a case of a 40-year-old who presented an expanding hematoma of the right side of the neck after a road traffic accident. Radiography of the right shoulder showed a midclavicular fracture. An arterial doppler of vessels showed a circulating hematoma in the contact of the right subclavian artery with a correct distality flow. Computed tomographic angiogram of the chest confirmed the diagnosis of a false aneurysm in the postvertebral portion of the right subclavian artery. The treatment was surgical and consisted of excision of the false aneurysm and a repair of the arterial injury by an arterial patch, the clavicle was fixed with a reconstruction plate and screws. Early intervention appears to be indicated due to the risk of thrombo-embolic complications. Endovascular repair appears to be the preferred treatment modalities, due to a lower rate of cardiopulmonary complications, but it is reserved for much selected cases.

The persistent sciatic artery: Report of ten cases.

OBJECTIVE: The persistent sciatic artery (PSA) is a rare congenital anomaly with a high rate of aneurysm formation, occlusion and stenosis. It may lead to severe complications including thrombosis, distal embolisation, or aneurysm rupture. We reported herein our experience in the management of PSA and its complications, and discuss the therapeutic options. METHODS: Eight patients with 10 PSA were managed in our institutions between 1985 and 2017. An analysis was done for the clinical data, surgical technique, and results. RESULTS: The series included six women and two men. The median age of the patients was 66,5 years (37-80 years). Physical examination found a pulsatile gluteal mass in five patients, sciatic neuropathy in two cases. Four patients had an acute ischemia of the lower limb. Cowie's sign was described in only two patients (diminished or absent femoral pulse but presence of popliteal pulse). Digital subtraction angiography was performed in all patients, and was completed with a computed tomography angiography (CTA) with a diagnosis of PSA, associated with a symptomatic aneurysmal lesion in seven cases and with an occlusion in one case. The treatment was surgical in all cases: bipolar exclusion of the aneurysm and bypass between the iliac artery and the PSA distal to the aneurysm was performed in four cases, only proximal and distal ligation was done in 2 other cases. A Chopart amputation was necessary in 2 cases. CONCLUSION: We consider that the treatment of PSA is usually surgical in symptomatic cases. Surgical techniques depend on symptoms and classification describing anatomy of the PSA. However, future studies should compare the open versus the endovascular approach to optimize patient selection criteria and identify the most safe and effective strategy. In an asymptomatic patient, PSA does not require any intervention; continued follow-up is required because of the high incidence of aneurysmal formation and the risk of thromboembolic events.

Pseudoaneurysm of external iliac artery after extracorporeal shock wave lithotripsy revealing Behçet disease.

Extracorporeal shock wave lithotripsy (ESWL) can lead to rare but severe arterial complications. The causal relationship of ESWL with arterial pseudoaneurysm formation in a patient with Behçet disease is discussed. A 35-year-old man presented with acute recrudescence of right flank pain caused by ureteral lithiasis immediately after having undergone a last session of ESWL. Abdominal examination revealed a painful pulsatile mass in the right iliac region. Contrast-enhanced computed tomography identified a pseudoaneurysm of the right external iliac artery in a patient with a medical history of Behçet disease. The pseudoaneurysm was treated endovascularly, including the use of a covered stent with intensive immunosuppressive therapy. We obtained successful exclusion of the pseudoaneurysm. This case highlights that arterial pseudoaneurysm may occur after ESWL in patients with Behçet disease. Strict follow-up after ESWL sessions is necessary.

[Case study of ruptured gastroduodenal artery aneurysm revealed by hematemesis]. / Anévrisme rompu de l'artère gastroduodénale révélé par des hématémèses: à propos d'un cas.

Gastroduodenal artery aneurysm is a rare vascular lesion, asymptomatic in the majority of cases. However, ruptured aneurysm is associated with poor prognosis and mortality can achieve a 40% rate. We here report the case of an 83-year-old patient with abrupt onset of non-specific abdominal pain associated with hematemesis. Endoscopy showed beating formation compressing the duodenal bulb with active bleeding. Abdominal computed tomography (CT) scan was performed which objectified gastro duodenal artery aneurysms involving the artery ostium and making endovascular treatment impossible to perform. Thus, the patient underwent open surgery based on flattening associated with aneurysm exclusion and then complemented by bulb plasty. Post-operative CT scan confirmed total exclusion of the aneurysm with preservation of hepatic circulation.

Emergency stent graft implantation for ruptured visceral artery pseudoaneurysm.

BACKGROUND: Literature series that include visceral artery pseudoaneurysms rarely separate them from true aneurysms, although they address different issues. Guidelines for optimal management of these lesions are lacking. We report our experience of stent graft treatment of these lesions with midterm results. METHODS: We retrospectively reviewed all patients with a visceral pseudoaneurysm who were treated with a stent graft in our institution. Patient history, clinical characteristics, procedure details, and outcome were recorded and analyzed. RESULTS: From March 2004 to June 2009, 10 consecutive patients (9 men), who were a mean age of 59 years, were treated for symptomatic visceral artery pseudoaneurysm, with hemorrhagic shock in 8 patients (80%), after pancreaticoduodenectomy in 8, gastrectomy in 1, and abdominal trauma in 1. A mean of 24 days (range, 7-60 days) passed between the initial surgery or trauma and pseudoaneurysm diagnosis. Septic complications were associated in six patients (60%). The pseudoaneurysm was in the hepatic artery in 8 patients, the splenic artery in 1, and the superior mesenteric artery in 1. Technical and clinical success was achieved in 80% of patients. Two failures of catheterization were followed by redo surgery and death (20%). No patients died postoperatively, and no complications among the patients who were treated successfully. Mean follow-up was 37 months (range, 10-63 months). All stent grafts were patent, with no signs of infection. Two patients died secondary to neoplasm. No rebleeding or recurrent aneurysms were noted. CONCLUSION: Stent graft exclusion of visceral artery pseudoaneurysm seems to be a valid therapeutic approach regardless of the patient's septic or hemodynamic status.
