Summary:Myocardial perforations with a central venous catheter are m in adults (67 cases published since 1968). These accidents are fatal in more than two-thirds of the cases owing to confusion caused by misleading symptoms which suggest pulmonary embolism. The perforation is generally localized in the right atrium (29 cases), less frequently in the right ventricle (1 8 cases). The superior vena cava is rarely affected (3 cases). The site of the perforation was not found in the other published cases. Clinical symptoms are signs of tamponade with disorders of cardiac hythm. An enlargement of the cardiac shadow and an abnormal position of the catheter, buckled or openly intrapericardial, make the diagnosis radiologically.Echocardiography provides some information, but this is often too late for practical application. The diagnosis is made with right catheterization when it shows an equalization of the diastolic pressures. This allows the patient to be watched closely following the pericardial tap, after which a surgical approach may be indicated and perfonned. Prevention of these iatrogenic accidents must be systematic and strictly controlled for.
Background: To ascertain the safety and mid-term outcomes of Rotarex ® S rotational atherectomy plus thrombectomy device (Straub Medical AG, Wangs, Switzerland) with or without adjunctive treatment (e.g., percutaneous transluminal angioplasty, PTA/drug-coated balloon, DCB/stenting) in patients with in-stent restenosis (ISR) or occlusion in the iliac and/or infrainguinal arteries.Methods: French multicenter retrospective study of all patients treated by in-stent percutaneous mechanical debulking (PMD) of the lower limbs with Rotarex ® S device between January 2013 and November 2018.
Results:The cohort consisted of 128 patients (88 men and 40 women), aged 39-94 years (mean, 66.7±12 years). All patients presented with cardio-vascular risk factors. Overall, 51.5% of patients had critical limb ischemia. The study demonstrated a technical success of 96.9% in the population with PMD and adjunctive PTA (95/128, 74.2%) or adjunctive DCB (16/128, 12.5%) or both (13/128, 10.2%). At 12-months follow-up, the primary clinical success/patency rate was 92.3% and the secondary clinical success/patency rate was 91.4%. Rate of limb salvage was 93.7%. Overall 32 (25%) reinterventions were reported with mean time from Rotarex ® S treatment to reintervention of 7.1±8.2 months. Target lesion revascularization (TLR) was 19.5% (25/128). Seven (5.5%) patients developed distal embolism that responded to endovascular treatment. At mean follow-up, major adverse events (MAE) observed were death (18/128, 14.1%), myocardial infarction (MI) (9/128, 7.0%), stroke (2/128, 1.6%) and renal failure (3/128, 2.3%).Conclusions: Recanalization with Rotarex ® S rotational atherectomy plus thrombectomy device is a practical choice for arterial ISR/occlusions of the iliac and/or infrainguinal arteries, regardless of the age of the thrombus, with satisfying TLR. Only adjunctive PTA is often necessary to further improve the recanalization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
