Antiphospholipid syndrome-induced ischemic stroke following pembrolizumab: Case report and systematic review.

Immune checkpoint inhibitors (ICI) improve the prognosis of patients with advanced non-small cell lung cancer. However, clinicians should be aware of potentially life-threatening immune-related adverse events (irAEs). We report a case of a 67-year-old man with lung adenocarcinoma who developed an acute ischemic stroke after the second administration of pembrolizumab.

A rare vascular complication of Eagle syndrome highlight by CTA with neck flexion.

We report a case of a 53-year-old woman admitted to the emergency department with left hemiplegia, tinnitus and palpitations. A cerebral and cervical computed tomography angiography revealed an acute large ischemic stroke on the right Sylvian territory, which was related to a dissection of the right internal carotid. Moreover, a left internal carotid pseudo-aneurysm was observed.

[Iliac arteriovenous fistula as a complication of lumbar disc surgery].

A 56-year-old man suffering from moderate dyspnea was hospitalised in the unit of surgery. Fifteen days before, he was subjected to a discectomy at L4-L5. The clinical examination demonstrated sinus tachycardia and hepatomegalia.

[Doppler study of gluteal arteries. A useful tool for excluding gluteal arterial pathology snd an important adjunct to lower limb Doppler studies].

Purpose: 1) To determine the negative predictive value (VPN) of duplex scan in patients complaining of buttock or hip pain and thereby to distinguish vascular claudication from other musculoskeletal or neurological diseases. 2) To show its complementarity in doppler investigation of lower limb arteries.

Materials And Methods: Prospective study by duplex scan and arteriography of 60 gluteal arteries in 30 consecutive patients referred to check up for lower limb arteriopathy or sexual impotence.

Emergency endovascular treatment of an acute traumatic rupture of the thoracic aorta complicated by a distal low-flow syndrome.

We report the case of a patient who suffered major trauma following a motorcycle accident that resulted in multiple fractures, bilateral hemopneumothorax, pulmonary contusions, and an isthmic rupture of the aorta with a pseudoaneurysm compressing the descending aorta. This compression was responsible for distal hypotension and low flow, leading to acute renal insufficiency and massive rhabdomyolysis. Due to the critical clinical status of the patient, which prevented any type of open thoracic surgery, endovascular treatment was performed.

Transcatheter embolization of pseudoaneurysms complicating pancreatitis.

Purpose: To evaluate the therapeutic role of angiography in patients with pseudoaneurysms complicating pancreatitis.

Methods: Thirteen symptomatic pseudoaneurysms were treated in nine patients with pancreatitis. Eight patients had chronic pancreatitis and pseudocyst and one had acute pancreatitis.

Corporeal veno-occlusive dysfunction: predominantly intracavernous muscular pathology.

Purpose: We investigated whether a relationship exists between the flow to maintain an erection obtained at cavernosometry and the alteration of intracavernous structures in impotent patients with corporeal veno-occlusive dysfunction and normal arterial inflow.

Materials And Methods: Computerized histomorphometric analysis of smooth muscle and elastic fibers, and endothelial cells was compared to the flow necessary to maintain erection after intracavernous vasoactive drug injection in 18 patients with corporeal veno-occlusive dysfunction.

Results: A significant correlation between percentage of smooth muscle fibers and flow to maintain erection was observed, while no correlation was noted with elastic fibers and endothelial cells.

Endovascular aortic stent-grafts: transcatheter embolization of persistent perigraft leaks.

Purpose: To assess efficacy of transcatheter embolization of peri prosthetic leaks from aortic stent-grafts

Materials And Methods: Eight patients with a long-standing (3-13 months) perigraft leak after stent-graft implantation underwent transcatheter embolization. Leakage was demonstrated at helical computed tomography (CT). Angiography was performed for evaluation of outflow vessels and transcatheter embolization.

[Placing of a Nitiol Memotherm prosthesis: personal experience].

The authors report their experience in the placement of a new Nitinol stent. Thirty eight stents were placed in 28 iliac arteries, 3 superficial femoral arteries, 1 popliteal artery, 2 subclavian arteries, and 2 veins of hemodialysis fistulae. The primary success rate was 100%, but several angioplasty balloons have been ruptured due to the specific configuration of the stent.

[Imaging of acquired pathologies of the thoracic aorta].

For many years, imaging of thoracic aorta has been dominated by angiography. Development of new imaging modalities has modified the diagnostic approach to thoracic aortic pathology. The knowledge of the advantages and limitations of each technique enables a better choice for patient evaluation, in particular under emergency conditions.

Idiopathic non-familial rectal and colonic varices requiring sigmoidorectal resection and coloanal anastomosis.

A 32-year-old male patient presenting with huge varices involving the sigmoid colon and the entire rectum down to the dentate line is described. There was no familial history of gastrointestinal bleeding. No particular aetiology was identified.

Correlation of nocturnal penile tumescence monitoring duplex ultrasonography and infusion cavernosometry for the diagnosis of erectile dysfunction.

Purpose: Nocturnal penile tumescence monitoring was compared to penile duplex ultrasonography and pharmaco-infusion cavernosometry in 50 cases of erectile dysfunction.

Materials And Methods: Nocturnal penile tumescence was evaluated in all patients as normal or abnormal according to standard general criteria. The results were compared to penile duplex ultrasonography parameters (peak systolic velocity, normal greater than 35 cm.

[Erectile dysfunction: the role of Rigiscan in the diagnosis].

Objective: Nocturnal penile tumescence (NPT) was performed in all patients and was evaluated as normal or abnormal according to standardized general criteria. The results of NPT were then compared to penile duplex ultrasonography parameters peak systolic velocity (normal > 35 cm/sec) and diastolic velocity (normal < 5 cm/sec), and to the flow rate needed to maintain erection (normal < 15 ml/min) with pharmaco-infusion cavernosometry.

Results: Of the 50 patients, 26 showed normal NPT where 25 patients (96%) had normal penile systolic velocity, 18 patients (69%) had normal penile diastolic velocity, and 22 patients (85%) showed normal flow to maintain erection.

Vertebral artery dissection. Case report.

Vertebral artery dissection is an uncommon but important cause of posterior stroke in young and middle aged adults. We report a case with a long term fluctuating ischemic symptoms due to bilateral spontaneous dissection. Etiology and treatment are discussed.

[Persistent left superior vena cava. Apropos of 2 cases].

Double superior vena cava with persistence of a left superior vena cava is rarely encountered. The prevalence in the general population is 0.3% but may reach 3 to 10% in patients with inborn heart diseases.

Treatment of glans hyperemia after penile revascularization by transcatheter embolization.

Glans hyperemia after penile revascularization is a well known complication normally treated by surgery. However, this reintervention is often difficult due to local fibrosis. We report a case of successful embolization after supra-selective catheterization of the deep dorsal vein through the surgical anastomosis.

[Radiologic diagnosis of renal cortical necrosis. Apropos of a case and review of the literature].

One case of renal cortical necrosis is reported. The results of ultrasound and angiographic imaging and the relevant literature are reviewed. The examinations, particularly selective angiography, are of great interest in the diagnostic and in the etiology of this disease.

[Iatrogenic femoral pseudo-aneurysm and arteriovenous fistula. Non-surgical treatment].

Pseudoaneurysm and arteriovenous fistulae are classical but unusual complications of femoral catheterism. The use of large diameter catheters, heparinotherapy and fibrinolysis constitute risk factors. These local complications are becoming more frequent resulting from an increase in interventional techniques.

[Computed tomography aspects of cerebral toxoplasmosis in AIDS].

We followed by CT 19 AIDS patients with cerebral toxoplasmosis. Diagnosis of cerebral toxoplasmosis was assessed on radiological and clinical basis, including the therapeutic response. CT allowed to confirm brain lesions (40 lesions in 19 patients) and to follow the evolution with treatment.

[Iatrogenic femoral pseudo-aneurysm. Analysis of the causes, diagnosis and treatment. Study of 12,248 arterial catheterizations].

Pseudoaneurysm is a classical but unusual complication of femoral catheterism. 22 cases are reviewed: 19 occurred after coronarography, 2 after peripheral percutaneous angioplasty and only one after a renal diagnostic arteriography. In all cases, the diagnosis of the pseudoaneurysm was established by I.

[Obstruction of the sigmoid colon due to an ovarian metastasis of colonic origin].

The authors present a case of left ovarian metastasis from colon carcinoma causing sigmoid obstruction. On US and CT the ovarian mass appears as a primary malignant lesion. The lesion caused a regular sigmoid stenosis which mimicked, on barium enema, a volvulus and screened the primary lesion.

[A case of multiple brain calcifications associated with hypoparathyroidism].

We report a case of extensive cerebral calcifications associated with hypoparathyroidism in a 82-year-old woman who has been thyroidectomized and received an antiepileptic treatment for 26 years after an episode of coma followed by confusion. We discuss the frequent confusion in terminology used for describing such cases, emphasizing the necessary distinction between Fahr's disease (extensive cerebral calcifications without abnormal phosphocalcium metabolism) and cerebral calcinosis associated with hypoparathyroidism.

[Laser assisted angioplasty].

Percutaneous laser thermal angioplasty with a hot tip fiber was used in 26 patients to recanalize 20 femoropopliteal occlusions, 5 iliac thromboses and one occlusion of the left subclavian artery. Initial angiographic success was achieved in 85% for the femoropopliteal lesions and in 60% for the iliac occlusions. Eight complications did occur, but none necessitated emergency bypass surgery.

Intravenous digital subtraction angiography. A criteria of brain death.

The absence of cerebral blood flow is the best criteria of cerebral death. Intravenous digital subtraction angiography (DSA) was performed in 110 patients with clinical signs of brain death. In 105 cases DSA, confirmed the stop of the intracranial circulation.
