Project description:An entrapment and breakage of coronary angioplasty catheter during coronary intervention is a rare but serious complication. Percutaneous transluminal coronary angioplasty (PTCA) catheter got entrapped and broken inside the left anterior descending artery (LAD) in a 58-year-old male patient. The whole length of the PTCA catheter was retrieved through an arteriotomy incision in LAD along with reversed saphenous vein graft to LAD, under cardiopulmonary bypass and cardioplegic arrest. We discuss here the various percutaneous retrieval techniques and surgical management of entrapped broken PTCA catheter and also the role of transesophageal echocardiography intraoperatively.

Project description:Thoracic aortic endovascular repair (TEVAR) is increasingly preferred as a treatment of choice in thoracic aortic diseases. Intravascular foreign body is one of the TEVAR-related complications similar to the other endovascular operations. Here, to the our best knowledge for the first time in the English literature, this report presents an extremely rare complication of a broken and stuck tip part of aortic stent-graft in the intravascular space and successful removal by using the coaxial technique. Thoracic aortic endovascular repair (TEVAR) has been increasingly preferred as the treatment of choice in thoracic aortic diseases (1). Endovascular treatment has been gaining popularity compared with open surgery due to its less invasive approach and rapid application, and allows the patient to easily return to daily life (2). However, TEVAR is associated with several specific complications including paraplegia, stroke, vascular injuries and local complications. These complications depend on vascular or nonvascular comorbidities, vascular anatomy, equipment, and experience of the provider (3-6). Intravascular foreign body could be among TEVAR-related complications similar to other endovascular operations (7). Several types of equipment, including guidewire, vascular sheath, or suboptimally uncoiled stents may get stuck in the intravascular space, causing complications (8). Herein, to the best of our knowledge, we present the first report in the English literature of broken and stuck tip part of an aortic stent-graft in the intravascular space and its successful removal using the coaxial technique.

Project description:Background: Little is known about the superiority of balloon angioplasty vs. stent implantation for femoropopliteal (FP) lesions according to subgroup. Methods and Results: This study involved 1,018 de novo (balloon angioplasty, n=462; stent implantation, n=556) and 114 in-stent restenosis (ISR) FP lesions (balloon angioplasty, n=69; stent implantation, n=45) treated with endovascular therapy. For de novo FP lesions, the 3-year primary patency rate was significantly better with stent implantation than with balloon angioplasty (61% vs. 69%, log-rank P=0.001), but it was similar for ISR FP lesions (40% vs. 43%, log-rank P=0.83). For de novo FP lesions, stent implantation was favorable in all subgroups except for female sex (hazard ratio [HR], 0.92; 95% CI: 0.65-1.31, P=0.66), critical limb ischemia (CLI; HR, 0.70; 95% CI: 0.46-1.06, P=0.10), calcified lesion (HR, 0.81; 95% CI: 0.46-1.39, P=0.44), and poor tibial run-off (HR, 0.86; 95% CI: 0.59-1.25, P=0.42) subgroups. No difference was found between the 2 treatment strategies for ISR FP lesions in the majority of subgroups. Stent implantation, however, was favorable in totally occluded ISR FP lesions (HR, 0.45; 95% CI: 0.21-1.01, P=0.05). Conclusions: The primary patency rate in de novo FP lesions for the 2 treatment strategies was similar in the female, calcified lesion, CLI, and poor tibial run-off subgroups. Stent implantation was superior to balloon angioplasty for totally occluded ISR FP lesions.

Project description:BackgroundThe current guidelines recommend both repeat stenting and drug-coated balloons (DCB) for in-stent restenosis (ISR) lesions, if technically feasible. However, real-world clinical data on the interventional strategies in patients with left main bifurcation (LMB)-ISR have not been elucidated.MethodsSeventy-five patients with LMB-ISR, who underwent percutaneous coronary intervention (PCI) between January 2009 and July 2015, were retrospectively reviewed for the present study (repeat drug eluting stent [DES] implantation [n = 51], DCB angioplasty [n = 24]).ResultsAnalysis of the baseline characteristics showed that the patients in the DCB group had a lower incidence of non-ST segment elevation myocardial infarction/ST segment elevation myocardial infarction at the index PCI (8.3% vs. 25.5%; p = 0.12), higher low-density lipoprotein-cholesterol level (92.9 mg/dL vs. 81.7 mg/dL; p = 0.09), and more "stent-in-stent" lesions (25% vs. 7.8%; p = 0.07) than those in the DES group. A smaller post-procedural minimal target lesion lumen diameter was also noted in the DCB group than in the DES group (2.71 mm vs. 2.85 mm; p = 0.03). The cumulative incidence rates of major adverse cardiac events (MACEs) were similar between both groups (median follow-up duration, 868 days; MACE rate, 25% in the DCB group vs. 25.5% in the DES group; p = 0.96). The multivariate Cox regression analysis indicated that the true bifurcation of ISR was an independent risk predictor of MACEs (hazard ratio, 4.62; 95% confidence interval, 1.572-13.561; p < 0.01).ConclusionsDES and DCB showed comparable long-term clinical results in patients with LMB-ISR lesions.

Project description:Objective: Symptomatic in-stent restenosis (sISR) is the major cause of medium- or long-term cerebral infarctions in patients who underwent percutaneous transluminal angioplasty and stenting for severe intracranial atherosclerotic stenosis. This study aims to evaluate the feasibility and safety of paclitaxel-coated balloon (PCB) angioplasty for the treatment of intracranial sISR. Methods: We report 11 cases of PCB angioplasty for intracranial sISR. Lesion locations and number were as follows: intracranial internal carotid artery (n = 4), M1 segment of middle cerebral artery (MCA) (n = 1), V4 segment of vertebral artery (n = 6). The technical success rate, periprocedural complications, and short-term outcome were retrospectively analyzed. Results: All procedures were successfully performed without periprocedural complication. Asymptomatic vessel dissection after PCB inflation occurred in one case. Postprocedural diffusion-weighted imaging (DWI) showed new asymptomatic ipsilateral infarction in one case. All 11 cases did not experience ipsilateral stroke or death within 30 days or ischemic stroke in the territory of the target artery between 31 and 90 days after procedure. Conclusion: This preliminary study indicates that PCB angioplasty is feasible and safe for the treatment of intracranial sISR. Further studies are needed to clarify its efficiency and long-term outcome.

Project description:We present a rare and interesting case, of a retrieval of a broken surgical knife blade, from the retroperitoneal space, through laparoscopic approach by a gynecology endoscopist. A 40-year-oId man underwent open lumbar discectomy surgery, when the surgical knife blade inadvertently broke, and was retained in the disc space. The broken blade could not be removed during the initial surgery. A second attempt was made to retrieve it; however, it migrated further anteriorly into the retroperitoneal space. Subsequently, a gynecology endoscopist was called in, who successfully retrieved the broken blade from the retroperitoneal space through laparoscopic approach. A four-port laparoscopic transperitoneal approach was performed. The broken fragment of the knife was found just medial to the left common iliac artery in the retroperitoneal space, which was removed. Operation time was 40 minutes and the postoperative course was uneventful.

Project description:Drug-coated balloons (DCB) are effective in treating in-stent restenosis (ISR) with neointimal proliferation after bare-metal stent (BMS) implantation, but it is unclear whether DCB are effective in treating BMS-ISR accompanied by thrombosis. An 84-year-old man with previous inferior myocardial infarction and atrial fibrillation developed acute myocardial infarction (AMI) during hospitalization for intracerebral hemorrhage. Emergent coronary angiography (CAG) revealed severe stenosis of the distal left circumflex coronary artery. We implanted a BMS to avoid long-term triple antithrombotic therapy. He received aspirin, clopidogrel, and rivaroxaban for 1 month and then received clopidogrel and rivaroxaban. Seventy days after BMS implantation, he developed AMI, and emergent CAG revealed occlusion of the BMS due to late stent thrombosis. After thrombus aspiration, intravascular ultrasound showed incomplete neointimal healing in the proximal portion of the stent and excessive neointimal proliferation in the distal portion of the stent. DCB angioplasty of the entire BMS was performed after scoring balloon pre-dilation. Seven months after BMS implantation, follow-up CAG revealed binary ISR. DCB angioplasty of the entire BMS was performed again after scoring balloon pre-dilation. Thirteen months after BMS implantation, follow-up CAG did not reveal recurrence of ISR. <Learning objective: Drug-coated balloons (DCB) were ineffective when there was excessive neointimal proliferation accompanied by thrombosis, but effective in binary in-stent restenosis (ISR). DCB may be ineffective in early ISR after bare-metal stent implantations and when there is excessive neointimal proliferation accompanied by thrombosis. Since the safety and efficacy of DCB to treat excessive neointimal proliferation occurring with late stent thrombosis is unclear, further studies are needed.>.

Project description:BackgroundThe role of atherectomy in treating femoropopliteal disease has been evolving rapidly. However, the clinical efficacy and safety of adjunctive atherectomy to percutaneous balloon angioplasty (BA) (plain balloon and drug-coated BA) remains controversial. We sought to perform a meta-analysis comparing atherectomy plus balloon angioplasty (ABA) versus BA alone in treating femoropopliteal disease.MethodsWe searched PubMed, Cochrane Central Register of Clinical Trials, EMBASE, and ClinicalTrials.gov (from inception through January 10, 2022) for studies comparing ABA versus BA for femoropopliteal disease. We used a random-effects model to calculate risk ratio (RR) with 95% CIs. Target lesion revascularization (TLR), primary patency, and bailout stenting were the primary outcomes.ResultsNine studies with 699 patients were included (4 randomized and 5 retrospective studies). Compared to BA alone, the ABA group showed a significant decrease in TLR driven by nonrandomized studies (RR 0.59; 95% CI, 0.40-0.85; P = .005) and bailout stenting (RR, 0.32; 95% CI, 0.21-0.48; P < .0001). There was no significant difference in TLR when the analysis was performed including only randomized trials. There was no significant difference in the primary patency between the 2 groups (RR, 1.04; 95% CI, 0.95-1.14; P = .37).ConclusionsData from randomized trials suggest that compared with BA alone, the combination of atherectomy and BA showed no difference in TLR or primary patency. In observational studies, TLR and bailout stenting were reduced in ABA group but there was no difference in primary patency. Further studies are needed to investigate the clinical outcomes of atherectomy combined with BA in femoropopliteal lesions compared with BA alone.

Project description:PurposeComplete removal of air bubbles from balloons for neurovascular angioplasty is cumbersome. We compared the preparation difficulty, air removal efficiency, and air collection pattern of six different balloon catheter preparation methods to propose a better preparation method for both initial and second balloon uses, especially for small-profile angioplasty balloon catheters.Materials and methodsA total of 18 neurovascular angioplasty balloon catheters with nominal diameters of 2 mm were prepared to test six different preparation methods: the instruction for use method (method A), simplified method using a syringe (method B) and four newly devised preparation methods using inflating devices (methods C-F). Serial radiographs were obtained while the balloons were gradually inflated. We measured the time for each preparation and the bubble number, analyzed their distribution in the balloon, and calculated the contrast filling ratio (contrast filling area/total balloon area) for initial and second ballooning. The whole process was repeated three times.ResultsThe preparation time varied widely (11.5 seconds [method D] to 73.3 seconds [method A]). On initial inflation, the contrast filling ratio at 8 atm was the highest (100%) with methods A and F. On second inflation, the ratio was again highest with method A (99.5%), followed by method F (99.2%). Initial ballooning tended to show a uniform pattern of single bubble in the distal segment of the balloon; in contrast, second ballooning showed varying patterns in which the bubbles were multiple and randomly distributed.ConclusionNone of the six methods were able to completely exclude air bubbles from the balloon catheters including the second ballooning; however, the method of repeating aspiration with high-volume inflating device (method F) could be a practical option considering the simplicity and efficiency of preparation.
