[Case study of ruptured gastroduodenal artery aneurysm revealed by hematemesis]

L'anévrisme de l'artère gastroduodénale est une lésion vasculaire rare, asymptomatique dans la majorité des cas. Cependant, en cas de rupture de l’anévrisme, le pronostic est mauvais et la mortalité peut atteindre 40%. Nous rapportons le cas d’un patient âgé de 83 ans, qui a présenté brutalement des douleurs abdominales non spécifiques, associées à des hématémèses, et chez qui une fibroscopie a révélé une formation battante comprimant le bulbe duodénal avec un saignement actif, une tomodensitométrie abdominale a été réalisé et a mis en évidence un anévrisme de l’artère gastroduodénale englobant son ostium, et rendant une prise en charge endovasculaire impossible. Une chirurgie ouverte a donc été réalisée, et a consisté en une mise à plat associée à une exclusion de l’anévrisme, puis complétée par une plastie du bulbe. Une tomodensitométrie post-opératoire a confirmé l’exclusion totale de l’anévrisme avec la conservation de la circulation hépatique.

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.

[Acute post-trauma dissection of the descending thoracic aorta]

BACKGROUND

Traumatic injury to the descending thoracic aorta other than the isthmus is rare, and little known. Acute post-trauma rupture may occur in a context of multiple or rarely unique localizations.

CASE REPORT

We report the case of a young man who was the victim of multiple injuries with an isolated rupture of the descending thoracic aorta. Early diagnosis and adapted endovascular treatment led to favorable outcome.

CONCLUSION

In 90% of cases, acute post-trauma rupture of the aorta in a single localization involve the isthmus. Rupture of the descending aorta is more exceptional but must not be missed. The pathophysiological mechanism and appropriate management are discussed in light of a review of the literature.

[Emergency endovascular treatment for ruptured post-traumatic pseudoaneurysm of the superior gluteal artery]

Pseudoaneurysms of the gluteal arteries are rare, often secondary to blunt or penetrating pelvic trauma. These pseudoaneurysms are initially asymptomatic and manifest after a variable delay ranging from a few weeks to many years after the initial trauma. The spontaneous outcome can be fatal in case of rupture. Previously, treatment of gluteal pseudoaneurysms was exclusively surgical, but the advent of endovascular techniques revolutionized management practices by decreasing perioperative morbidity and offering results comparable to those of surgery. We report the case of a patient admitted for emergency management of a ruptured post-traumatic pseudoaneurysm of the superior gluteal artery that had occurred 20 days after penetrating buttock trauma. Selective embolization was successful.

[Spontaneous false aneurysm of the extracranial internal carotid artery - during pregnancy]

Extracranial carotid false aneurysms are rare but serious because of the high risk of rupture and thromboembolic ischemic strokes. Although hemodynamic and hormonal physiological changes in pregnant women may favor arterial rupture and the development of false aneurysms, only one case of extracranial carotid false aneurysm related to pregnancy has been reported in the literature. Surgical repair is still the treatment of choice of these lesions. We report a case of spontaneous false aneurysm of the extracranial internal carotid artery occurring at the end of pregnancy. The surgical procedure consisted in resection of the false aneurysm with interposition of a prosthetic graft. The follow-up was uneventful.

[An axillary-subclavian artery aneurysm in pre-rupture revealing Marfan syndrome]

Marfan syndrome is an autosomal dominant disorder of connective tissue which has many clinical symptoms and whose prognosis depends on associated cardiovascular complications, dominated by proximal aortic disorders. Peripheral arterial aneurysms are rare during Marfan syndrome and are exceptionally indicative of the disease. We report the case of a large aneurysm of the axillary-subclavian artery in pre-rupture revealing a new case of Marfan syndrome. Treatment consisted in surgical repair by resection of the aneurysm and performing a venous bypass graft; the postoperative course was uneventful.

[Traumatic dissection of the left renal pedicle in a young adult]

Blunt trauma rarely causes renal pedicle dissection. Clinical signs are minimal and inconsistently reported. The diagnosis is based on computed tomographic angiography; arteriography is still useful when revascularization is considered. We report here a case of traumatic dissection with thrombosis of a juxta-aortic renal pedicle monitored in the intensive care unit. An endovascular procedure could not be proposed because of the juxta-aortic localization.

[Claude Bernard-Horner syndrome revealing spontaneous aneurysm of the vertebral artery]

False aneurysms of the extracranial vertebral artery (FAVA) are rare because of the path of the artery at the level of the transverse holes. They can be secondary to penetrating cervical trauma, spontaneous in the course of an angiopathy such as Ehlers-Danlos syndrome, or iatrogenic. We report the case of a 31-year-old woman who presented a syndrome of Claude Bernard-Horner related to a spontaneous FAVA. The angioscanner confirmed the diagnosis and the patient underwent successful surgical treatment of the false aneurysm with ligature of the vertebral artery. Outcome was favorable.

Multilayer Flow Modulator Treatment of Abdominal and Thoracoabdominal Aortic Aneurysms With Side Branch Coverage: Outcomes From a Prospective Single-Center Moroccan Registry

PURPOSE

To evaluate endovascular repair of thoracoabdominal aortic aneurysms (TAAA) and abdominal aortic aneurysms (AAA) using the Multilayer Flow Modulator (MFM) in high-surgical-risk patients with at least one covered branch vessel.

METHODS

In this prospective single-center nonrandomized trial, 18 patients (mean age 61.1 years; 16 men) with TAAA (n=10, mean diameter 74.4 mm) and AAA (n=8, mean diameter 67.8 mm) were treated with the MFM between June 2009 and September 2012. The primary safety endpoints were all-cause mortality at 30 days and 12 months and neurological complications. The primary efficacy endpoint was overall procedure success, defined as patency of covered branch vessels, reductions in aneurysm diameter, and sac thrombus formation.

RESULTS

The technical success rate was 100% (53 study devices implanted, mean stented length 273 mm). Through mean follow-up of 13.4 months, all 61 covered branch vessels remained patent; there were no neurologic complications, ruptures, or instances of device migration, kinking, or fracture. Three patients died, 2 of unrelated causes and one of an undetermined cause. Only one reintervention with an additional MFM implanted at 5 years was required for a type I endoleak in a young patient with natural growth. Carefully planned and executed diameter and volume measurements demonstrated aneurysm shrinkage and progressive sac thrombus formation for both patient groups.

CONCLUSION

Through midterm follow-up, treatment of high-surgical-risk TAAA and AAA patients with the MFM appears to be safe and effective, maintaining branch vessel patency and reducing rupture risk through reduction of aneurysm diameter and modulation of flow dynamics. Longer term follow-up is needed.

Multiple Visceral Artery Aneurysms: An Uncommon Manifestation of Antineutrophil Cytoplasmic Antibody Vasculitis

The antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis mainly affect small vessels. They are an exceptional etiology of visceral artery aneurysms, which are themselves unusual and potentially serious vascular disease. We report the case of a patient followed for vasculitis associated with ANCA with kidney disease who presented with symptomatic aneurysm of the inferior mesenteric artery and aneurysm of the superior mesenteric artery.

[Peripheral arterial pseudo-aneurysm in Behçet's disease: Report of two cases]

Behçet's disease is a systemic vasculitis of unknown etiopathogenesis. Arterial events such as pseudo-aneurysms are rare and may be the mode of occurrence of the disease. These pseudo-aneurysms tend, regardless of size, to progress rapidly to life-threatening rupture. We report two cases of arterial pseudo-aneurysms that ruptured. Treatment consisted of surgical repair in one case and arterial ligation in the other; the postoperative course was uneventful in both cases.

Drop-Attacks Revealing a Cervical Cystic Lymphangioma

We report the case of a 28-year-old man who presented in emergency for recurrent drop-attacks. Ultrasound imaging and angio computed tomography revealed a left cervical tumor, and the patient underwent surgery. The diagnosis of cystic lymphangioma was done on the anatomic characteristics of the surgical specimen and the results of the histological study. This is the first reported case of late diagnosis of a cervical cystic lymphangioma revealed by recurrent drops attack.

[Endovascular treatment of acute limb ischemia occurred after popliteal stent fracture]

Angioplasty stenting of popliteal artery lesions is a common procedure in endovascular surgery. Stent fractures in popliteal artery maybe asymptomatic or cause restenosis, false-aneurysm or acute thrombosis. We report one case of acute limb ischemia occurred after a popliteal stent fracture placed four months earlier. The patient underwent an angioplasty stenting, completed with thrombolysis and thrombectomy. This case-report aims to illustrate complications of stent fracture in popliteal artery and possibility's to manage it by endovascular approach.

[Endovascular treatment of intra-thoracic left subclavian artery aneurysm]

Aneurysms of the subclavian artery are rare, and remain asymptomatic until complications. We report one case of atherosclerotic aneurysm of the proximal portion of the left subclavian artery fortuitously discovered and successfully treated by endovascular stent graft. This case report aims to illustrate endovascular procedures in the management of difficult access lesions or in high-risk surgical patients.

Acute systemic embolism due to an idiopathic floating thrombus of the thoracic aorta: success of medical management: a case report

Background

Idiopathic thoracic aortic mural thrombi are rare. They can be responsible for dramatic systemic embolization. Early treatment is imperative because of their high morbidity and mortality rate.

Case presentation

A 55-year-old previously healthy Moroccan male came in an array of acute right lower limbs pain and abdominal sensibility. Severe systemic embolism involving the lower extremities, spleen, kidney, and digestive tract, due to an idiopathic mural thrombus of the thoracic aorta was diagnosed. He received medical treatment leading to the complete disappearance of the thrombus and the effects caused by the latter.

Conclusions

When faced unexplained peripheral embolization, research for a thrombus of the thoracic aorta should be performed. Medical treatment should be considered for its management, especially in patients with high surgical risk.

[Exceptional association of bilateral popliteal aneurysm with an abdominal aortic aneurysm in Marfan syndrome]

Marfan syndrome is an autosomal dominant disorder with rheumatoid, ophthalmological, neurological, cutaneous and cardiovascular manifestations. Aneurysmal lesions affecting both the abdominal aorta and the peripheral arteries are not often described in the literature. We report a case associating a bilateral popliteal aneurysm and an aneurysm of the infra-renal abdominal aorta.

[The aneurysms of digestive system arteries: three cases]

The aneurysms of digestive arteries are a rare pathological entity, with a risk of rupture associated to a high mortality rate, often asymptomatic, then they are discovered incidentally during a exam for other diagnostic purposes. We report three cases of digestive aneurysms, one of celiac trunk, one of mesenteric artery on behçet disease, and one of splenic artery, which were treated surgically with success.

[Infected aneurysm of a branch of the superior mesenteric artery]

Aneurysm of the superior mesenteric artery is a rare finding. The risk of rupture is difficult to predict and manage. We report the case of a young woman who developed an aneurysm of the superior mesenteric artery in a context of bacterial endocarditis. Surgical resection without revascularization was successful.

[Middle aortic syndrome: a case report]

Middle aortic syndrome (MAS) results from a diffuse narrowing of the distal thoracic or abdominal aorta commonly involving both the visceral and renal arteries. Congenital, acquired, inflammatory, and infectious etiologies have been described. Symptoms typically occur within the first three decades of life and include hypertension, lower extremity claudication, and mesenteric ischemia. The condition is considered a life-threatening emergency as a result of the complications associated with severe hypertension. Diagnosis is made with magnetic resonance and computed tomography angiography. Surgical bypass grafting is the optimal method of treatment and must be tailored depending on the distribution of disease. We report one case of MAS treated with thoracic aorta to abdominal aorta bypass and reimplantation of the right renal artery.

[Aneurysm of the coeliac trunk. A case report]

Aneurysm of the coeliac artery is a rare vascular problem. The most serious clinical complication of coeliac artery aneurysm is rupture. Because of this, surgery is traditionally recommended. This paper presents a case of a coeliac artery aneurysm treated by open surgery.

[Abdominal aortic aneurysm and Behçet's disease: four cases]

Behçet's disease is an uncommon systemic process generally developing during the third or fourth decade of life. Recurrent inflammatory lesions are characteristic. Cardiovascular involvement, which may be arterial or venous, is rare but with particularly severe prognosis. Four cases of abdominal aortic aneurysm are reported. One patient underwent emergency surgery for acute rupture. All patients were male, age range 29-45 years, mean age 36.5 years. Three patients were followed for Behçet's disease. Surgical revascularization was performed in all four patients, mainly with prosthetic grafts, one with patch aortoplasty. The postoperative period was complicated by paraplegia and thrombosis of the prosthetic graft in the patient who underwent emergency surgery. On the basis of these cases and cases reported in the literature, it can be concluded that morbidity and mortality are high because of the etiology underlying vascular involvement in Behçet's disease.

[Aneurysm of a persistent sciatic artery: five case reports]

We report five cases of a persistent sciatic artery. The lesion was unilateral in all cases. Four patients were treated by exclusion of the aneurysm with ligature of the internal iliac artery with an associated femoropopliteal bypass in two. Surgical treatment was declined by one patient. We discuss the embryology, pathology, clinical aspects and surgical procedures involved.

[Paratesticular rhabdomyosarcomas. Apropos of a case]

A case of paratesticular rhabdomyosarcoma in a 23 year-old patient is reported. Clinical signs are like any intrascrotal tumor. Scrotal ultrasound, CT scan and immunohistochemical markers are necessary for the diagnosis and stadification of this cancer. Orchidectomy followed by radiotherapy and/or chemotherapy is the usual treatment. Prognosis depends on the tumoral stage.
