Endovascular treatment of calcific lesions of the common femoral artery using atherectomy device associated with scoring balloon angioplasty in diabetic patients with high "major amputation" risk.

OBJECTIVES: To investigate the outcomes of patients with calcific lesions in the common femoral artery undergoing endovascular procedures with atherectomy device and scoring balloon angioplasty combined with treatment of steno-occlusive disease of the remaining arterial districts of the lower limb. METHODS: Between January 2015 and December 2018, 11 diabetic patients at high risk for "major amputation", with calcific lesions of the common femoral artery and ischemic ulcers requiring endovascular treatment were retrospectively evaluated. Technical success was defined as revascularization of the common femoral artery with a residual stenosis lower than 30%. Primary endpoints were an immediate increase of perilesional transcutaneous oxygen pressure (TCPO2) > 40 mmHg, ulcerative lesions improvement up to healing or skin flaps re-epithelialization after minor amputation, limb rescue with rejected major amputation, and resolution of rest pain if present. RESULTS: The success rate of the revascularization procedures was 100%. No patient underwent surgical conversion. One case of peri-operative bleeding at the brachial access site was observed. There were no cases of arterial dissection or undesired distal embolization. The average baseline value of perilesional TCPO2 was 21.8 ± 9.2 mmHg. The mean TCPO2 value was 57.4 ± 7.2 mmHg three days after the procedure (P < 0.05), and 51.2 ± 9.8 mmHg 15 days after (P < 0.05). Minor amputations were performed in five patients with advanced ulcerative lesions. No major amputations were performed in the follow-up period. At 14 months follow-up, one patient developed new occlusion of the CFA for extension from the external iliac artery and underwent a new endovascular procedure. We observed an overall primary patency rate of 91% and a primary assisted patency rate of 100% in our 18-month follow-up. CONCLUSIONS: Endovascular approach for severely calcified atherosclerotic lesions of the common femoral artery seems to represent a valid therapeutic option associated with promising results in terms of clinical outcome and low complication rates.

Comparison between X-ray-hysterosalpingography and 3 Tesla magnetic resonance-hysterosalpingography in the assessment of the tubal patency in the cause of female infertility.

OBJECTIVES: XR-hysterosalpingography currently represents the gold standard for tubal pathology evaluation. Magnetic resonance-HSG is an innovative technique. With our study, we aim to comprehend if and how MR-HSG, compared to traditional XR-HSG, could give us this additional information in the diagnostic/therapeutic process. MATERIALS AND METHODS: This study included 19 patients between 30 and 42 years old (average age 37.7) affected by infertility. Patients underwent contextually both XR-HSG and MR-HSG, using a single catheterization. The dynamic MR-HSG exam consisted a MR sequence during contrast administration through the cervical catheter. RESULTS: Both XR-HSG and MR-HSG documented that 15 of the 19 patients had bilateral tubal patency, while four patients had monolateral tubal patency. However, MR-HSG allowed us to diagnose additional findings: Two active endometriosis foci in adnexal localization and a condition of adenomyosis A unicornuate uterus malformation A submucous uterine myoma near the tubal ostium A decrease of the ovarian reserve in a patient So MR-HSG could potentially detect in 10/19 (52%) women the cause of their infertility, compared to 4/19 (21%) detected with XR-HSG and about 30% of women would have resulted as false negatives if we only used XR-HSG. Finally, with a questionnaire, we demonstrated that MR-HSG is less painful than XR-HSG. CONCLUSIONS: These data thus confirm that XR-HSG and MR-HSG present the same diagnostic of assessing tubal patency. We also demonstrated that MR-HSG is able to detect further collateral findings that could likewise be a possible therapeutic target and it could possibly become the new gold standard in female infertility diagnostics.

Super selective arterial embolization to treat radiation-induced hemorrhagic gastritis: a case report and review of the literature.

Radiation-induced hemorrhagic gastritis (RIHG) is a rare but potentially fatal event following radiotherapy for locally advanced gastric cancer; the treatment of this condition is not standardized. Only few cases of RIHG have been reported, treated with different therapeutic approaches. Here we report the case of a 79-year-old patient who underwent subtotal gastrectomy for gastric cancer, followed by adjuvant chemo-radiotherapy. Approximately 3 months after the end of the treatment, she developed recurrent diffuse bleeding originating from the entire mucosa of the gastric pouch and from a marginal ulcer. As the bleeding was refractory to several endoscopic treatments and surgery was not indicated, the patient underwent two sessions of transcatheter selective arterial embolization, with resolution of bleeding. Arterial embolization has already been reported for the treatment of hemorrhagic cystitis, developing after irradiation of the pelvis for prostate, bladder, rectum, and cervix cancer. However, to our knowledge, it has never been reported as a treatment for hemorrhagic gastritis. Based on this case, we suggest arterial embolization as an option in the management of RIHG, when standard endoscopic treatment fails.

Polyethylene Glycol Epirubicin-Loaded Transcatheter Arterial Chemoembolization Procedures Utilizing a Combined Approach with 100 and 200 µm Microspheres: A Promising Alternative to Current Standards.

PURPOSE: To report clinical effectiveness, toxicity profile, and prognostic factors of combined 100 µm ± 25 and 200 µm ± 50 epirubicin-loaded polyethylene glycol (PEG) microsphere drug-eluting embolic transcatheter arterial chemoembolization protocol in patients with hepatocellular carcinoma. MATERIALS AND METHODS: In this prospective, single-center, single-arm study with 18 months of follow-up, 36 consecutive patients (mean age 69.9 y ± 10.8; 26 men, 10 women; 54 naïve lesions) were treated. Embolization was initiated with 100 µm ± 25 microspheres, and if stasis (10 heart beats) was not achieved, 200 µm ± 50 microspheres were administered. Each syringe (2 mL) of PEG microsphere was loaded with 50 mg of epirubicin. Results were evaluated using Modified Response Evaluation Criteria In Solid Tumors with multidetector computed tomography/magnetic resonance imaging at 1, 3-6, 9-12, and 15-18 months. Toxicity profile was assessed by laboratory testing before and after the procedure. Complications were recorded. Postembolization syndrome (PES) was defined as onset of fever/nausea/pain after the procedure. Patient/lesion characteristics and treatment results were correlated with predicted outcome using regression analysis. Child-Pugh score was A in 86.1% of patients (31/36) and B in 13.9% (5/36). RESULTS: In 10 of 21 lesions, < 2 cm in diameter (47.5%) stasis was achieved with 100 µm ± 25 microspheres only, whereas all other lesions required adjunctive treatment with 200 µm ± 50 microspheres. Reported adverse events were grade 1 acute liver bile duct injury (3/39 cases, 7.7%) and PES (grade 2; 3/39 cases, 7.7%). Complete response (CR) at 1, 3-6, 9-12, and 15-18 months was 61.1%, 65.5%, 63.63%, and 62.5%. Objective response (CR + partial response) at 1, 3-6, 9-12, and 15-18 months was 83.3%, 65.85%, 63.63%, and 62.5%. No single factor (laboratory testing, etiology, patient status, hepatic status, tumor characteristics, administration protocol) predicted outcomes except for albumin level at baseline for CR (P < .05, odds ratio = 1.09). CONCLUSIONS: The combined microsphere sizing strategy was technically feasible and yielded promising results in terms of effectiveness and toxicity.

A review discussing the use of polyethylene glycol microspheres in the treatment of hepatocellular carcinoma.

Transarterial chemoembolization (TACE) is indicated in unresectable hepatocellular carcinoma and allows the delivery of embolics inside tumor vascularization to reduce blood supply and release gradually the drug. This lowers the systemic exposure to chemotherapeutics, while increasing their local concentration and tissue necrosis that is higher than conventional TACE. The technology of TACE has seen the introduction of several types of embolics that are made of different materials. Available embolics for TACE include: drug-eluting beads (DC beads), acrylic copolymer, tris-acrylic microspheres and polyethylene glycol (PEG) microspheres. Few studies are available on PEG embolics and their use for TACE. This review focuses on the efficacy and safety of TACE performed with PEG microspheres for the treatment of hepatocellular carcinoma and discusses future therapeutic advantages.

Diagnostic accuracy of 3T magnetic resonance imaging in the preoperative localisation of parathyroid adenomas: comparison with ultrasound and 99mTc-sestamibi scans.

OBJECTIVES: To evaluate the diagnostic performance of 3TMRI in comparison with ultrasound (US) and 99mTc-sestamibi scan for presurgical localisation of parathyroid adenomas (PTAs) in patients with primary hyperparathyroidism (PHPT). METHODS: Fifty-seven patients affected by PHPT were prospectively enrolled and underwent US, 99mTc-sestamibi and 3TMRI. T2-weighted and post-contrast T1-weighted Iterative decomposition of water and fat with Echo Asymmetry and Least squares estimation (IDEAL) sequences were acquired. Diagnostic performance of US, 99mTc-sestamibi and MRI in localising PTAs to correct quadrant were compared according to surgical and pathological findings. RESULTS: According to surgical findings, US correctly localised 41/46 PTAs (sensitivity of 89.1%; specificity 97.5%; PPV 93.1% and NPV 95.6%); 99mTc-sestamibi correctly localised 38/46 PTAs (sensitivity 83.6%, specificity 98.3%, PPV 95% and NPV 93.7%). US and 99mTc-sestamibi combined had a sensitivity of 93.4% (43/46 PTAs), specificity of 98.3%, PPV 95% and NPV 98.3%. MRI correctly localised 45/46 PTAs (sensitivity 97.8%; specificity 97.5%; PPV 93.7% and NPV 99.2%). MRI was able to detect six adenomas missed by 99mTc-sestamibi and two adenomas missed by US. MRI and US were able to detect all enlarged parathyroid glands in patients with multiglandular disease. MRI identified six of seven ectopic adenomas. CONCLUSIONS: Our study demonstrated high diagnostic performance of 3T MRI in the preoperative PTAs quadrant localisation, as well as in patients with multiglandular disease and ectopic PTAs. MRI may be preferred to adequately select patient candidates for minimally invasive parathyroidectomy (MIP). KEY POINTS: • PTA(s) quadrant localisation by 3TMRI was more accurate than US+99mTc-sestamibi. • MRI identified all enlarged glands in multiglandular disease similarly to US. • MRI identified 6/7 ectopic PTAs similarly to 99mTc-sestamibi. • Presurgical PTA(s) localisation by 3TMRI select the optimal candidates for MIP.

Comparison of Image Quality and Diagnostic Performance of Cone-Beam CT during Drug-Eluting Embolic Transarterial Chemoembolization and Multidetector CT in the Detection of Hepatocellular Carcinoma.

PURPOSE: To compare image quality and diagnostic performance of cone-beam computed tomography (CT) and multidetector CT in the detection of hypervascular hepatocellular carcinoma (HCC) in patients with cirrhosis undergoing transarterial chemoembolization with drug-eluting embolic agents. MATERIALS AND METHODS: Fifty-five consecutive patients referred for chemoembolization of hypervascular HCC were prospectively enrolled. Imaging included preprocedural multidetector CT within 1 month before planned treatment, intraprocedural cone-beam CT, and 1-month follow-up multidetector CT. Analysis of image quality was performed with calculations of lesion-to-liver contrast-to-noise ratio (LLCNR) and lesion-to-liver signal-to-noise-ratio (LLSNR). One-month follow-up multidetector CT was considered the reference standard for the detection of HCC nodules. RESULTS: Median LLCNR values were 3.94 (95% confidence interval [CI], 3.06-5.05) for preprocedural multidetector CT and 6.90 (95% CI, 5.17-7.77) for intraprocedural cone-beam CT (P < .0001). Median LLSNR values were 11.53 (95% CI, 9.51-12.44) for preprocedural multidetector CT and 9.36 (95% CI, 8.12-10.39) for intraprocedural cone-beam CT (P < .0104). Preprocedural multidetector CT detected 115 hypervascular nodules with typical HCC behavior, and cone-beam CT detected 15 additional hypervascular nodules that were also visible on 1-month follow-up multidetector CT. CONCLUSIONS: Cone-beam CT has a significantly higher diagnostic performance compared with preprocedural multidetector CT in the detection of HCCs and can influence management of patients with cirrhosis by identifying particularly aggressive tumors.

Role of 3.0 Tesla magnetic resonance hysterosalpingography in the diagnostic work-up of female infertility.

BACKGROUND: Imaging evaluation plays a crucial role in the diagnostic work-up of female infertility. In recent years, the possibility to evaluate tubal patency using 1.5 Tesla magnetic resonance (1.5T MR) has been studied. PURPOSE: To assess the feasibility of 3.0 Tesla magnetic resonance (3.0T MR) hysterosalpingography and its role in the diagnostic work-up of female infertility and to evaluate if this fast "one-stop-shop" imaging approach should be proposed as a first-line examination. MATERIAL AND METHODS: A total of 116 infertile women were enrolled in this prospective study; all underwent 3.0T MR hysterosalpingography. After standard imaging of the pelvis, tubal patency was assessed by acquiring 3D dynamic time-resolved T1-weighted (T1W) sequences during manual injection of 4-5 mL of contrast solution consisting of gadolinium and normal sterile saline. Images were evaluated by two radiologists with different experience in MR imaging (MRI). RESULTS: The examination was successfully completed in 96.5% of cases, failure rate was 3.5%. Dynamic sequences showed bilateral tubal patency in 64.3%, unilateral tubal patency in 25.9%, and bilateral tubal occlusion in 9.8%. Extratubal abnormalities were found in 69.9% of patients. Comprehensive analysis of morphological and dynamic sequences showed extratubal abnormalities in 43.1% of patients with bilateral tubal patency. CONCLUSION: 3.0T MR hysterosalpingography is a feasible, simple, fast, safe, and well-tolerated examination, which allows evaluation of tubal patency and other pelvic causes of female infertility in a single session, and it may thus represent a "one-stop-shop" solution in female infertility diagnostic work-up.

Preliminary clinical experience with a dedicated interventional robotic system for CT-guided biopsies of lung lesions: a comparison with the conventional manual technique.

OBJECTIVE: Evaluate the performance of a robotic system for CT-guided lung biopsy in comparison to the conventional manual technique. MATERIALS AND METHODS: One hundred patients referred for CT-guided lung biopsy were randomly assigned to group A (robot-assisted procedure) or group B (conventional procedure). Size, distance from entry point and position in lung of target lesions were evaluated to assess homogeneity differences between the two groups. Procedure duration, dose length product (DLP), precision of needle positioning, diagnostic performance of the biopsy and rate of complications were evaluated to assess the clinical performance of the robotic system as compared to the conventional technique. RESULTS: All biopsies were successfully performed. The size (p = 0.41), distance from entry point (p = 0.86) and position in lung (p = 0.32) of target lesions were similar in both groups (p = 0.05). Procedure duration and radiation dose were significantly reduced in group A as compared to group B (p = 0.001). Precision of needle positioning, diagnostic performance of the biopsy and rate of complications were similar in both groups (p = 0.05). CONCLUSION: Robot-assisted CT-guided lung biopsy can be performed safely and with high diagnostic accuracy, reducing procedure duration and radiation dose in comparison to the conventional manual technique. KEY POINTS: • CT-guided biopsy is the main procedure to obtain diagnosis in lung tumours. • The robotic device facilitates percutaneous needle placement under CT guidance. • Robot-assisted CT-guided lung biopsy reduces procedure duration and radiation dose.

Aspiration thrombectomy of M2 segment in acute ischemic stroke: The clinical reality in a neurovascular reference center.

OBJECTIVE: Our study aimed to evaluate safety, efficacy and clinical outcomes in patients with acute ischemic stroke with occlusion of M2 segment treated with thromboaspiration. MATERIALS AND METHODS: A retrospective study was conducted in patients with ischemic stroke of M2 segment undergoing endovascular thromboaspiration. The time period analyzed was from October 2015 until February 2021. Thromboaspiration was performed with AXS Catalyst 5 (Stryker) or AXS Catalyst 6 (Stryker) catheters. The following parameters were assessed: risk factors for ischemic stroke, National Institutes of Health Stroke Scale (entry and discharge), pre-procedural fibrinolysis, pre-procedural and 24-h Alberta Stroke Program Early CT Score, recanalization time, number of passages for recanalization, Thrombolysis in cerebral infarction scale score, periprocedural complications, Modified Rankin Scale score at 90 days from procedure and mortality. RESULTS: 90 patients were included in the study. The mean age was 75 ± 11.1 with National Institutes of Health Stroke Scale at entry 13 ± 5 and 8 ± 4 at discharge. Pre-procedural fibrinolysis were performed in 40 patients. Pre-procedural Alberta Stroke Program Early CT Score were 8.8 ± 1.3 and 6.9 ± 2.4 after 24 h from the procedure. Time of recanalization from onset of symptoms was 300 ± 82 min. Number of passages for recanalization were 1.8 ± 1.1. Thrombolysis in cerebral infarction scale score ≥ 2b were obtained in 90 % of procedures. After 90 days 33 % of patient obtained an Modified Rankin Scale between 0 and 1 (between 0 and 2 was 40 %). We didn't detect any complication in 64 % of cases (subarachnoid haemorrhage in 2 %, HI1 and HI 2 in 15 %, PH1 in 9 % of patients, PH2 in 6 % of patients). CONCLUSIONS: This paper confirms the usefulness and safety of thrombospiration in patients with ischemic stroke in the M2 segment with low intra-operative risks, high technical success and positive impact on the outcome of the patients.

Endovascular treatment of acute arteriosclerotic vertebrobasilar occlusion: A single center experience.

OBJECTIVES: Few experiences on vertebrobasilar occlusion over underlying intracranial atherosclerotic disease have been reported in literature and the optimal strategy on how to perform a mechanical thrombectomy is unclear. The aim of this paper is to bring our experience based on patients admitted with acute vertebrobasilar occlusion with underlying atheromatous lesions. MATERIALS AND METHODS: Several data were collected from August 2009 to October 2022 including clinical history, pre- and post-treatment neurological objectivity, diagnostic images and angiographic procedural images, and clinical outcome at 6 months. We selected 13 patients from August 2009 to October 2022, 12 men and 1 woman, aged 40 to 82 years (mean age, 62.6 years). RESULTS: Mechanical thrombectomy with a thromboaspiration was performed in all patients as beginning of the procedure. In three patients, the procedures resulted in excellent angiographic result and clinical outcome, while in three patients, we observed a failure of the procedural and clinical outcome. For residual intracranial stenosis in three patients, an angioplasty was performed obtaining an ischemic area related to the posterior circulation. In four patients, a stent was placed, in three patients, we obtained a good clinical outcome with a mRS between 0 and 2, while one treatment resulted in death, probably due to a late endovascular treatment. CONCLUSIONS: Endovascular treatment with stent deployment appears to result in an excellent outcome in patients with occlusion of the vertebrobasilar circulation in cases of occlusion on atheromatic plaque. The degree of residual stenosis after thrombospiration can significantly affect subsequent type of treatment.

Overlapping features of hepatic complications after hematopoietic cell transplantation in a rare T-cell lymphoma: A clinical challenge.

We present the case of a young adult, who developed several hepatic post-HCT complications, which made differential diagnosis extremely difficult.

Combined treatments with microballoon catheters and multiple cryoablation probes for shoulder-subclavian soft tissue hemangiopericytoma: A case report.

We describe a case of a 65-year-old woman affected by hemangiopericytoma/solitary fibrous tumor of the right shoulder-subclavian region. Hemangiopericytoma/solitary fibrous tumor is a rare tumor of uncertain malignancy. She reports shoulder pain and inability to abduct the arm and elevate the shoulder. Imaging showed erosion of the scapula. The patient underwent 5 sessions of "on demand" embolization in the previous 2 years scheduled for recurrence of symptoms-swelling of tissues. Further 2 treatments were achieved through embolization via 2 different microballoon catheter combined with percutaneous cryoablation with 5 probes. Images after the treatment demonstrate a marked reduction in the hypervascularized area and an increase in the necrosis area. So, this combined treatment is safety and reproducible also in extrahepatic tissue.

Possible use of Digital Variance Angiography in Liver Transarterial Chemoembolization: A Retrospective Observational Study.

PURPOSE: Digital variance angiography (DVA), a recently developed image processing technology, provided higher contrast-to-noise ratio (CNR) and better image quality (IQ) during lower limb interventions than digital subtraction angiography (DSA). Our aim was to investigate whether this quality improvement can be observed also during liver transarterial chemoembolization (TACE). MATERIALS AND METHODS: We retrospectively compared the CNR and IQ parameters of DSA and DVA images from 25 patients (65% male, mean ± SD age: 67.5 ± 11.2 years) underwent TACE intervention at our institute. CNR was calculated on 50 images. IQ of every image set was evaluated by 5 experts using 4-grade Likert scales. Both single image evaluation and paired image comparison were performed in a blinded and randomized manner. The diagnostic value was evaluated based on the possibility to identify lesions and feeding arteries. RESULTS: DVA provided significantly higher CNR (mean CNRDVA/CNRDSA was 1.33). DVA images received significantly higher individual Likert score (mean ± SEM 3.34 ± 0,08 vs. 2.89 ± 0.11, Wilcoxon signed-rank p < 0.001) and proved to be superior also in paired comparisons (median comparison score 1.60 [IQR:2.40], one sample Wilcoxon p < 0.001 compared to equal quality level). DSA could not detect lesion and feeding artery in 28 and 36% of cases, and allowed clear detection only in 22% and 16%, respectively. In contrast, DVA failed only in 8 and 18% and clearly revealed lesions and feeding arteries in 32 and 26%, respectively. CONCLUSION: In our study, DVA provided higher quality images and better diagnostic insight than DSA; therefore, DVA could represent a useful tool in liver TACE interventions. LEVEL OF EVIDENCE: III Non-consecutive study.

Untailored vs. Gender- and Body-Mass-Index-Tailored Skeletal Muscle Mass Index (SMI) to Assess Sarcopenia in Advanced Head and Neck Squamous Cell Carcinoma (HNSCC).

(1) Background: Sarcopenia lasting >1 year might be considered a chronic condition in many HNSCC patients. CT-scan-derived Skeletal Muscle Mass Index (SMI) is an established surrogate of sarcopenia; yet, the cut-off reported in the literature (literature-based, lb-SMI < 43.2) is mainly based on the risk of chemoradiotherapy-induced toxicity, and the optimal value to discriminate OS is under-investigated. (2) Methods: The effect on OS of the lb-SMI cutoff was compared with an untailored OS-oriented SMI cutoff obtained in a cohort of consecutive advanced HNSCC patients treated with primary chemoradiotherapy, bio-chemotherapy or chemo-immunotherapy (cohort-specific, cs-SMI cutoff). Gender- and BMI-tailored (gt-SMI and bt-SMI) cut-offs were also evaluated. Cutoff values were identified by using the maximally selected rank statistics for OS. (3) Results: In 115 HNSCC patients, the cs-SMI cutoff was 31.50, which was lower compared to the lb-SMI reported cut-off. The optimal cut-off separately determined in females, males, overweight and non-overweight patients were 46.02, 34.37, 27.32 and 34.73, respectively. gt-SMI categorization had the highest effect on survival (p < 0.0001); its prognostic value was independent of the treatment setting or the primary location and was retained in a multivariate cox-regression analysis for OS including other HNSCC-specific prognostic factors (p = 0.0004). (4) Conclusions: A tailored SMI assessment would improve clinical management of sarcopenia in chemoradiotherapy-, bio-chemotherapy- or chemo-immunotherapy-treated HNSCC patients. Gender-based SMI could be used for prognostication in HNSCC patients.

Liver-Specific Contrast-Enhanced Magnetic Resonance Cholangio-Pancreatography (Ce-MRCP) in Non-Invasive Diagnosis of Iatrogenic Biliary Leakage.

Current non-invasive diagnostic modalities of iatrogenic bile leak (BL) are not particularly sensitive and often fail to localise the BL origin. Percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiopancreatography (ERCP) are considered the gold standard, yet are invasive studies with potential complications. Ce-MRCP has been not comprehensively studied in this setting but may prove particularly helpful given its non-invasive nature and the anatomical dynamic detail. This paper reports a monocentric retrospective study of BL patients referred between January 2018 and November 2022 submitted to Ce-MRCP followed by PTC. The primary outcome was the accuracy of Ce-MRCP in detecting and localising BL compared to PTC and ERCP. Blood tests, coexisting cholangitis features and time for leak resolution were also investigated. Thirty-nine patients were included. Liver-specific contrast-enhanced MRCP detected BL in 69% of cases. The BL localisation was 100% accurate. Total bilirubin above 4 mg/dL was significantly associated with false negative results of Ce-MRCP. Ce-MRCP is highly accurate in detecting and localising BL, but sensitivity is significantly reduced by a high bilirubin level. Ce-MRCP may be very useful in early BL diagnosis and in accurate pre-treatment planning, but can only be reliably used in selected patients with TB < 4 mg/dL. Non-surgical techniques, both radiological and endoscopic, are proven to be effective in terms of leak resolution.

A Rare but Fatal Behçet Variant: The Hughes-Stovin Syndrome-Successful Case Report and New Evidence from Literature Review.

Hughes-Stovin syndrome (HSS) is a rare potentially fatal vasculitis supposedly belonging to the spectrum of Behçet disease without ocular involvement. HSS tends to play by a temporal pattern, starting with thrombosis and followed by formation of pulmonary aneurysms. Since its mortality can reach 25% of cases, early recognition and appropriate therapy represent the major clinical challenges. We describe a rare case of HSS successfully treated via multidisciplinary management by an endovascular approach and immunosuppressive therapy.

Carotid artery stenting during endovascular thrombectomy for acute ischemic stroke with tandem occlusion: the Italian Registry of Endovascular Treatment in Acute Stroke.

PURPOSE: The management of tandem extracranial internal carotid artery and intracranial large vessel occlusion during endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) has been under-investigated. We sought to investigate outcomes of AIS patients with tandem occlusion (TO) treated with carotid artery stenting (CAS) compared to those not treated with CAS (no-CAS) during EVT. METHODS: We performed a cohort study using data from AIS patients enrolled in the Italian Registry of Endovascular Treatment in Acute Stroke. Outcomes were 3 months' mortality, functional outcome, complete and successful recanalization, any intracranial hemorrhage, parenchymal hematoma and symptomatic intracerebral hemorrhage. RESULTS: Among 466 AIS patients with TO, CAS patients were 122 and no-CAS patients were 226 (118 excluded). After adjustment for unbalanced variables, CAS was associated with a lower rate of 3 months' mortality (OR 0.407, 95% CI 0.171-0.969, p = 0.042). After adjustment for pre-defined variables, CAS was associated with a lower rate of 3 months' mortality (aOR 0.430, 95% CI 0.187-0.989, p = 0.047) and a higher rate of complete recanalization (aOR 1.986, 95% CI 1.121-3.518, p = 0.019), successful recanalization (aOR 2.433, 95% CI 1.263-4.686, p = 0.008) and parenchymal hematoma (aOR 2.876, 95% CI 1.173-7.050, p = 0.021). CAS was associated with lower 3 months mortality (OR 0.373, 95% CI 0.141-0.982, p = 0.046) and higher rates of successful recanalization (OR 2.082, 95% CI 1.099-3.942, p = 0.024) after adjustment for variables associated with 3 months' mortality and successful recanalization, respectively. CONCLUSIONS: Among AIS patients with TO, CAS during EVT was associated with a higher rate of successful reperfusion and a lower rate of 3 months' mortality.
