Rupture d’anévrisme géant de l’artère fémorale commune révélant une maladie de Behçet

Vascular involvement in Behçet's disease is rare. Aneurysmal arterial involvement is the severe form of the disease, it constitutes a therapeutic challenge given its severity, and frequent secondary complications, especially at anastomosis. The systematic immunosuppressive drug treatment and surgical technique thoroughness can reduce relapse rate. We report the case of a young man in whom a ruptured false aneurysm of the common femoral artery revealed Behçet's disease. He underwent an open repair, with prosthetic arterial reconstruction, and anastomosis reinforcement with teflon.     

Compression nerveuse et veineuse profonde par un faux anévrysme de l’artère fémorale superficielle au cours d’une exostose multiple

The multiple exostosis is a hereditary bone tumour. Generally, its complications are benign and are related to compressing surrounding structures such as nerves and vessels. This is the case of a 52-year-old woman with a family history of multiple exostosis, which was complicated by a pseudoaneurysm of the right superficial femoral artery. The delay in diagnosis was allowed to develop this pseudoaneurysm which caused nervous and deep venous compression.     

Anévrisme géant de l’artère pulmonaire : aspects étiologiques et évolutifs exceptionnels sur 17 ans

True pulmonary artery aneurysm (AAP) is rare and represent less than 1% of intra-thoracic aneurysms. We report a case of a AAP in a patient with a likely cor triatrium sinister, with an obstructive membrane responsible for pulmonary hypertension, explaining AAP. The long-term evolution of 17 years is made to an uncomplicated myocardial infarction. The patient died eight months later suddenly probably due to the rupture of the PAA.     

Une hématémèse révélant un faux anévrisme de l’artère hépatique

The false aneurysm of the hepatic artery (HA) is a rare and severe. A potentially fatal. It follows a non-specific clinical symptoms. The significance of this observation is to bring a unique mode of revelation of a false aneurysm by upper gastrointestinal bleeding due to a fistula communicating the false aneurysm and the duodenum.     

Facteurs prédictifs d’amputation après angioplastie de l’artère iliaque chez les patients avec artériopathie sévère

IntroductionDespite the success of angioplasty of the iliac artery, this technique remains associated with significant amputation rates. The purpose of this study was to identify predictive factors for lower limb amputation after iliac angioplasty in patients with critical ischemia.MethodsWe reported a retrospective study including patients who successfully underwent angioplasty of the iliac artery between 2014 and 2018. The primary endpoint was limb salvage at 1 month. The variables were studied in univariate and multivariate analysis.ResultsOur study included 86 patients. The median age was 57 ± 10 and the sex ratio was 4.7. Cardiovascular risk factors were represented by smoking in 14 cases (16.3%), diabetes in 25 cases (29.1%), arterial hypertension in 2 cases (2.3%) and dyslipidemia in 2 cases (2.3%). Seventy patients (81.3%) were classified as stage 4 according to the Leriche and Fontaine classification and 16 patients (18.7%) were classified as stage 3. The lesions were stenosing in 48 cases (55.8%) and occlusive in 38 cases (44.2%). These lesions were classified according to the TASC classification “Trans-Atlantic-Society-Consensus” in TASC A-B in 61 cases (70.9%) and TASC C-D in 35 cases (29.1%). Distal arteritis was found in 8 cases (9.3%). Balloon angioplasty was performed in 36 cases (41.8%) and angioplasty stenting in 50 cases (58.2%). At 1 month, the amputation rate was 9.3%. Univariate analysis showed that diabetes and smoking were the most important factors associated with amputation (respectively P = 0.007, OR = 9.31, 95% CI = [1.73–50.07] and P = 0.022; OR = 6.8; 95% CI = [1.46 to 31.61]). Multivariate analysis showed that diabetes and distal arteritis were the predictive factors for amputation (respectively P = 0.034, OR = 21.06, 95% CI = [1.25 to 354.46] and P = 0.008, OR = 11,61, 95% CI = [1.88 to 71.69]).ConclusionDiabetes and distal arteritis are the predictive factors for lower limb amputation after iliac angioplasty.     

Facteurs de risque de progression des calcifications des artères coronaires après 5 ans d’évolution en dialyse

BackgroundAlthough progression of coronary artery calcification (CAC) has been established as an important marker for cardiovascular morbidity, very few studies have studied it in end-stage renal disease patients. Thus we examined and evaluate risk factors of calcification changes in dialysis patients.MethodAmong 28 hemodialysis (HD) patients, CAC was measured in Agatston units at baseline and after five years using the 64 multi-slice ultra-fast CT. The HD patients were classified as progressors or no progressors according to the change in the CAC score across these 2 measurements.ResultsOver an average 63 months follow-up, participants without CAC at baseline had no incident CAC. The progression of CAC was slow and was found only in 6 patients (21.4%). It was significantly associated with several cardiovascular risk factors, namely, older age (P = 0.03), diabetes (P = 0.05), male sex (P = 0.02), hypercholesterolemia (P = 0.05), anemia (P = 0.017), inflammation (P = 0.05), and hyperphosphataemia (P = 0.012). However, calcemia, parathormone levels, dialysis duration, tobacco, high blood pressure and dialysis dose did not seem to influence the progression of CAC in our series. A strong association was found between basal calcification scores and Delta increment at 5 years.ConclusionsOur study suggests that CAC progression in dialysis is a complex phenomenon, associated with several risk factors with special regard to elevated basal scores. This progression can be avoided or slowed with appropriate management, which must begin in the early stages of chronic kidney disease.     

Rupture colmatée d'un anévrisme de valsalva d’évolution favorable après chirurgie

Aneurysm of the sinus of Valsalva is a rare cardiac condition, which could be either acquired or congenital. The most frequent complication is a rupture into right cavities or more rarely into left cavities or pericardium.Rupture could be either asymptomatic or poorly tolerated with hemodynamic instability, acute heart failure or sudden death.We report the case of a 24-year-old patient with no past medical history presenting with a partially ruptured sinus of Valsalva into the pericardium and in whom the initial diagnosis was idiopathic pericardial effusion; we describe diagnostic modalities and management     

Vascularite de l’artère hépatique : à propos d’un cas d’atteinte d’organe isolée

Introduction

Vasculitis usually have a systemic involvement. Rare cases of localized vasculitis have been described, but the exclusive involvement of the hepatic artery is exceptional. We report the case of a patient who developed a vasculitis of the right and left hepatic arteries.

Embolisation des anévrysmes de l’artère splénique : traitement de choix. À propos d’un cas et revue de la littérature

Splenic artery aneurysms constitute 60% of digestive artery aneurysms. They are often discovered incidentally and by imaging. Currently, endovascular treatment is considered the first-line treatment, as it is less invasive with less morbidity and mortality than surgery. An aggressive approach in their management is certainly justified because the overall mortality of ruptured splenic aneurysms is 25%. False splenic aneurysms have a greater potential for rupture than true aneurysms because they grow faster. Endovascular treatment is generally indicated for aneurysms larger than 2 cm or with an increase in size of more than 0.5 cm/year. Embolization is rarely associated with an infarction of the spleen due to the good supply of short gastric vessels. Embolization is performed using different materials including coils, which can be used alone or with other embolic agents. Post-embolization syndrome can be seen with persistent pain, fever and other systemic symptoms. Endovascular treatment compared to open surgery is associated with better quality of life and appears to be the most cost-effective strategy. Endovascular treatment and especially coil embolization are starting to be the standard treatment. Surgical and laparoscopic treatment are reserved for ruptured aneurysms which are burdened with significant mortality, especially in pregnant women. We report the case of a 66-year-old female patient in whom a splenic artery aneurysm was discovered incidentally during an ultrasound for an ovarian cyst.     

Sténose de l’artère rénale à distance d’une dénervation rénale pour HTA résistante

The onset of renal artery stenosis following a renal denervation is rare and occurs in the first few months after renal denervation. We report the onset of renal artery stenosis a long time after the renal denervation for resistant hypertension. This is a 74 year-old patient who stopped smoking in 1980 and who was treated for dyslipidemia with a revascularized coronary artery disease in 2011, a well-stabilized peripheral arterial disease since 2001, a stable asymptomatic carotid atheroma and a good kidney function. His hypertension known since 1995 became resistant. After the control of renal arteries by angio-CT scan, he had a renal denervation in October 2012. His blood pressure decreased 3 months later confirmed by self-blood pressure monitoring (SBPM) and ambulatory blood pressure monitoring (ABPM) with a CT scan with a non-significant renal artery stenosis in January 2014. He remained normotensive under treatment until July 2015 but his hypertension became uncontrolled at the end of 2015 then resistant and severe confirmed by SBPM in April 2017, despite a 5-drug antihypertensive treatment associated to atorvastatin and clopidogrel confirmed by SBPM in April 2017. A left post-ostial renal artery stenosis with decrease in size of left kidney and cortex as compared to 2011 was detected at CT and treated by angioplasty. It was associated with a rapid decrease in blood pressure but unfortunately a new increase related to a restenosis occurred at the end of 2017, which justified a new angioplasty. Discussion about the etiology and the management of this renal post-denervation late stenosis.
