RESUMEN

Acute mesenteric ischemia (AMI) is a severe medical condition defined by insufficient vascular supply to the small bowel through mesenteric vessels, resulting in necrosis and eventual gangrene of bowel walls. We present the case of a 64-year-old man with recrudescence of prolonged epigastric pain at rest of few hours duration, cold sweating and episodes of vomiting. A computed tomography scan of his abdomen revealed multiple filling defects in the mid-distal part of the superior mesenteric artery (SMA) and the proximal part of jejunal branches, associated with small intestine walls thickening, suggesting SMA thromboembolism and initial intestinal ischemia. Considering the absence of signs of peritonitis at the abdominal examination and the presence of multiple arterial emboli was decided to perform an endovascular treatment with ultrasound assisted catheter-directed thrombolysis with EkoSonic Endovascular System-EKOS, which resulted in complete dissolution of the multiple emboli and improved blood flow into the intestine wall. The day after the procedure the patient's pain improved significantly and 5 days after he was discharged home asymptomatic on warfarin anticoagulation. After 1 year of follow-up the patient is fine with no further episodes of mesenteric ischemia or other embolisms.

RESUMEN

OBJECTIVE: We report our experience with simultaneous localization and thoracoscopic removal for nonpalpable undiagnosed pulmonary nodules. METHODS: All patients with nonpalpable lesions requiring video-assisted thoracoscopic surgery (VATS) wedge resection underwent localization of the targets and surgical removal in a hybrid operating room. Lesions were considered nonpalpable if they were small (<1 cm), deep (>1 cm from the surface), subsolid, or located within a dystrophic area. In all cases, intraoperative cone-beam computed tomography was performed for nodule localization and targeting, metal hookwires, or coils were alternatively used for intraoperative marking. RESULTS: From April 2016 to November 2019, 39 image-guided VATS (iVATS) were performed. The mean lesion size was 12 ± 6 mm. The mean distance from the deep edge of the lesion to the pleural surface was 24 ± 9 mm. The localization was performed with 20 hookwires and 19 coils. iVATS localization was successful in 36 patients (92.3%). Thirty-seven wedge resections were completed by VATS, 2 (5%) required conversion to thoracotomy. In 9 patients with intraoperative diagnosis of lung cancer, a lobectomy was performed (7 VATS and 2 thoracotomies). Mean length of iVATS localization was 30 ± 13 minutes. Median postoperative length of stay was 4 days (IQR 3 to 5). CONCLUSIONS: iVATS seems to be a helpful tool for simultaneous localization and removal of nonpalpable nodules. A versatile approach using different devices seems advisable for the removal of targets in every clinical scenario reducing VATS conversion rate. Future research is required to compare iVATS with traditional preoperative localization techniques.

RESUMEN

Management of the symptomatic multiple stenosis of supra-aortic vessels (MSSVs) in a "bovine" aortic arch (BAA) configuration is infrequently reported. The optimal treatment choice remains debatable. A successful hybrid treatment for a proximal critical stenosis of the innominate and left common carotid artery was performed in a high-risk patient with a tandem symptomatic lesion in the right carotid bifurcation and a concentric vulnerable plaque in the bovine trunk. This case supports the feasibility, safety, and efficacy of a combined carotid bifurcation endarterectomy and retrograde kissing stenting of common carotid arteries with cerebral protection after evaluation of radiological, anatomical, and clinical parameters.

RESUMEN

AIM: The aim of the paper is to report the clinical outcome after prostatic artery embolisation (PAE) in 13 consecutive patients with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). MATERIALS AND METHODS: From May 2012 to October 2013, we performed PAE in 13 consecutive patients (mean age 75.9 years) with BPH and LUTS and refractory to medical therapy; seven patients had an indwelling bladder catheter. Clinical follow-up (mean follow-up time 244 days) was performed using the international prostate symptoms score (IPSS), quality of life (QoL), the international index of erectile function (IIEF), blood prostatic specific antigen (PSA) testing and transrectal prostatic ultrasound (US) scan with volume and weight calculation at 3, 6 and 12 months. Pre-procedural CT angiography (CTA) was done for vascular mapping. Embolisation was performed using Embosphere (300-500 micron). Technical success was defined when selective prostatic arterial embolisation was completed in at least one pelvic side. Clinical success was defined when symptoms and quality of life were improved. RESULTS: PAE was technically successful in 12/13 patients (92%). In one patient, PAE was not performed because of tortuosity and atherosclerosis of iliac arteries. PAE was completed bilaterally in 9/13 (75%) patients and unilaterally in three (27%). All patients removed the bladder catheter from 4 days to 4 weeks after PAE. We obtained a reduction in IPSS (mean, 17.1 points), an increase in IIEF (mean, 2.6 points), an improvement in Qol (mean, 2.6 points) and a volume reduction (mean, 28%) at 12 months. CONCLUSIONS: Consistent with the literature, our experience showed the feasibility, safety and efficacy of PAE in the management of patients with LUTS related to BPH. PAE may play an important role in patients in whom medical therapy has failed, who are not candidates for surgery or transurethral prostatic resection (TURP) or refuse any surgical treatment. Larger case series and comparative studies with standard TURP can confirm the validity of the technique.

RESUMEN

PURPOSE: The present study was performed to analyze the midterm results (five consecutive patients, 2-year follow-up) of the endovascular management of visceral artery aneurysms using the Cardiatis Multilayer Flow Modulator (CMFM) (Cardiatis, Isnes, Belgium), a self-expandable stent. MATERIALS AND METHODS: From August 2009 to January 2011, we implanted five CMFMs in five patients (all men; mean age 73 years) to treat two common hepatic artery aneurysms, one celiac trunk aneurysm, one splenic artery aneurysm, and one superior mesenteric artery aneurysm (diameter 25-81 mm). The primary end point was technical success. The secondary end point was stent patency, absence of aneurysm rupture or reperfusion, and shrinking of the sac at 6-, 12-, and 24-month follow-up using computed tomography angiography. Follow-up ranged from 24 to 48 months (mean 31.2). RESULTS: Technical success was achieved in all patients. Complete exclusion of the aneurysm with sac shrinking was achieved in two patients. Two stents became occluded at 6- and 24-month follow-up, respectively; both patients were asymptomatic and were not retreated. One patient developed sac reperfusion due to incomplete aneurysm exclusion. CONCLUSION: Long-term results in a wider population are needed to validate the effectiveness of the CMFM.
