Abstract Background Renal artery intramural haematoma (IMH) is a rare cause of renal artery obstruction after stenting. Diagnosis and treatment are difficult as there are only a few cases reported. Case summary We present the case of sudden-onset abdominal pain and non-functional kidney 3 days after renal artery stent implantation. Subacute luminal narrowing of the renal artery was initially diagnosed using computed tomography angiography and renal artery angiography, and a final diagnosis of subacute renal artery IMH was made using intravascular ultrasound (IVUS). Subsequently, the patient was treated with percutaneous transluminal angioplasty from far to near and another stent implantation. At the third month follow-up, blood pressure and renal function were normal. Discussion This case suggests that IVUS could be useful for qualifying and treating the subacute renal artery IMH.

Objective Pulmonary vein stenosis (PVS) is a serious complication in patients with atrial fibrillation (AF) receiving radiofrequency catheter ablation (RFCA). We therefore examined these patients’ clinical characteristics in relation to PVS occurrence. Method We retrospectively analyzed the clinical symptoms, diagnostic procedures, and treatment strategies in patients with AF who developed PVS after RFCA. Results Among 205 patients with AF who underwent RFCA, five (2.44%) developed PVS (all men; age 44–64 years; AF history 12–60 months; 2 paroxysmal AF, 3 persistent AF). One patient underwent two RFCA sessions and the others received one. The time to PVS diagnosed by pulmonary vein computed tomography angiography (CTA) was 3 to 21 months. PVS symptoms included dyspnea and hemoptysis. Nine pulmonary veins developed PVS. Single mild PVS occurred in two asymptomatic patients and multiple PVS or single severe PVS in three symptomatic patients who underwent pulmonary vein angiography and stent placement. Symptoms in the three patients significantly improved after stent implantation; however, stent restenosis occurred 1 year later in one case. Conclusion PVS is a rare complication of RFCA for AF that can be diagnosed by CTA. Pulmonary vein stent implantation can remarkably improve the symptoms, but stent restenosis may occur.

Recurrent urethral stricture is one of the biggest problems in urology. Urethral stents as an alternative treatment to traditional methods  has been used since  1985    in the treatment of urethral strictures. The stone formation in the Memotherm urethral stent implantation area is a rare complication. We report the case of a 67-year-old man who presented a stone in the Memotherm urethral stent implantation area after 6 years from the urethral stent surgery.

Abstract Aims The no reflow phenomenon is a not rare complication that occurs in up to 30% of patients with acute coronary syndrome undergoing myocardial reperfusion by percutaneous coronary intervention. The use of coronary artery thrombus aspiration or distal embolization protection systems has reduced the risk of distal embolization and no-reflow phenomenon. Methods and results We describe the case of a 77 year old female suffering from hypertension presented at our emergency department for inferior STEMI. An urgent coronary angiography was performed, showing a three-vessel coronary artery disease with right coronary artery sub-occluded in the middle segment (culprit lesion), with a voluminous endoluminal minus image, as intracoronary thrombosis. Before performing the coronary angioplasty, a Spider FX3 filter was placed on the distal segment of the right coronary artery; thrombus aspiration was performed, which was ineffective, then angioplasty and Zotarolimus eluting stent implantation in the mid segment of the right coronary artery. After stent implantation, an image of minus was highlighted inside the basket of the filter, as a migrated and incarcerated thrombotic formation; then, the filter was removed. During the removal of the filter, longitudinal crush of the distal portion of the stent is caused, with limitation of the downstream flow, in the absence of haemodynamic instability. The stent was recrossed with Fielder XT guidewire supported by Turnpike LP Microcatheter. Multiple dilations werenperformed with semi-compliant and non-compliant increasing-caliber balloons and then Zotarolimus eluting stent implantation, in partial overlap with the distal portion of the previously implanted stent, with TIMI flow 3. The echocardiogram showed a normal global systolic function, with alterations in regional kinetics. On the 6th day, angioplasty and Zotarolimus eluting stent implantation was performed on the mid-proximal segment of the left anterior descending artery. During the hospitalization the patient was stable and has been discharged in good condition on the ninth day. Conclusions The interest of this case is the evidence of a rare complication related to the use of distal embolization protection system, probably due to an incomplete closure of the filter before removal, due to the high amount of thrombotic material inside it. The rapid recrossing of the stent after the longitudinal crush, the angioplasty and the second stent implantation, led to a quick flow restoration, without haemodynamic and clinical consequences on the patient's outcome.

Tuberculosis Therapy

Abdominal tuberculosis is one of common forms of extra-pulmonary tuberculosis. However, portal vein involvement leading to portal venous stenosis and portal hypertension is a rare complication in abdominal tuberculosis. Because of the non-specific presentations and insensitive response to anti-tuberculosis therapy of the lesions involving portal vein, it continues to be both a diagnostic and treatment challenge. We have reported a 22-year-old woman presented with massive ascites and pleural effusion, which was proved to be TB infection by pleural biopsy. After standard anti-tuberculosis therapy, her systemic symptoms completely resolved while ascites worsened with serum-ascites albumin gradient >11 g/L. Contrast-enhanced computed tomography and portal venography showed severe main portal vein stenosis from compression by multiple calcified hilar lymph nodes. Finally, the patient was diagnosed with portal venous stenosis due to lymphadenopathy after abdominal tuberculosis infection. Portal venous angioplasty by balloon dilation with stent implantation was performed and continued anti-tuberculosis therapy were administrated after discharge. The ascites resolved promptly with no recurrence occurred during the six-month follow-up. Refractory ascites due to portal venous stenosis is an uncommon vascular complication of abdominal tuberculosis. Portal venous angioplasty with stent placement could be a safe and effective treatment for irreversible vascular lesions after anti-tuberculosis therapy.

AbstractObjective:To define optimal thromboprophylaxis strategy after stent implantation in superior or total cavopulmonary connections.Background:Stent thrombosis is a rare complication of intravascular stenting, with a perceived higher risk in single-ventricle patients.Methods:All patients who underwent stent implantation within superior or total cavopulmonary connections (caval vein, innominate vein, Fontan, or branch pulmonary arteries) were included. Cohort was divided into aspirin therapy alone versus advanced anticoagulation, including warfarin, enoxaparin, heparin, or clopidogrel. Primary endpoint was in-stent or downstream thrombus, and secondary endpoints included bleeding complications.Results:A total of 58 patients with single-ventricle circulation underwent 72 stent implantations. Of them 14 stents (19%) were implanted post-superior cavopulmonary connection and 58 (81%) post-total cavopulmonary connection. Indications for stenting included vessel/conduit stenosis (67%), external compression (18%), and thrombotic occlusion (15%). Advanced anticoagulation was prescribed for 32 (44%) patients and aspirin for 40 (56%) patients. Median follow up was 1.1 (25th–75th percentile, 0.5–2.6) years. Echocardiograms were available in 71 patients (99%), and advanced imaging in 44 patients (61%). Thrombosis was present in two patients on advanced anticoagulation (6.3%) and none noted in patients on aspirin (p = 0.187). Both patients with in-stent thrombus underwent initial stenting due to occlusive left pulmonary artery thrombus acutely post-superior cavopulmonary connection. There were seven (22%) significant bleeding complications for advanced anticoagulation and none for aspirin (p < 0.001).Conclusions:Antithrombotic strategy does not appear to affect rates of in-stent thrombus in single-ventricle circulations. Aspirin alone may be sufficient for most patients undergoing stent implantation, while pre-existing thrombus may warrant advanced anticoagulation.
