Mechanical thrombectomy using retrievable stents or stent retriever devices has become the mainstay of intra-arterial therapy for acute ischemic stroke. The recent publication of a series of positive trials supporting intra-arterial therapy as standard of care for the treatment of large vessel occlusion will likely further increase stent retriever use. Rarely, premature stent detachment during thrombectomy may be encountered. In our multicenter case series, we found a rate of detachment of less than 1% (n = 7/1,067), and all were first-generation Solitaire FR devices. A review of the US Food and Drug Administration database of device experience yielded 90 individual adverse reports of detachment. There were 82, 1 and 7 detachments of Solitaire FR (first generation), Solitaire FR2 (second generation) and Trevo devices, respectively. We conclude with a brief overview of the technical and procedural considerations which may be helpful in avoiding this rare complication.

Carotid artery free-floating thrombus (FFT) is a rare but clinically significant cause of embolic stroke. Treatment has historically been confined to carotid surgery or best medical therapy, with neither option proved to be superior. However, recent advancements in endovascular interventions have heralded a new age of innovative management strategies for vascular disease. We present three distinct cases of stroke secondary to carotid artery FFT, successfully treated with stent retriever endovascular thrombectomy.

Background Achieving adequate fixation and healing of small proximal pole acute scaphoid fractures can be surgically challenging due to both fragment size and tenuous vascularity. Purpose The purpose of this study was to demonstrate that this injury can be managed successfully with osteosynthesis using a “micro” small diameter compression screw with distal radius bone graft with leading and trailing screw threads less than 2.8 mm. Patients and Methods Patients with proximal pole scaphoid fragments comprising less than 20% of the entire scaphoid were included. Fixation was accomplished from a dorsal approach with a micro headless compression screw and distal radius bone graft. Six patients were included. Average follow-up was 44 months (range, 11–92). Results Mean proximal pole fragment size was 14% (range, 9–18%) of the entire scaphoid. The mean immobilization time was 6 weeks, time-to-union of 6 weeks, and final flexion/extension arc of 88°/87°. All patients had a successful union, and no patient had deterioration in range of motion, avascular necrosis, or fragmentation of the proximal pole. Conclusion Small diameter screws with a maximal thread diameter of ≤ 2.8 mm can be used to fix the union of proximal pole acute scaphoid fractures comprising less than 20% of the total area with good success. Level of Evidence Therapeutic case series, Level IV.

Marginal Bone Loss

To determine the marginal bone loss and the survival, success and failure rates of narrow dental implants, a systematic literature search was carried out in the MEDLINE (Pubmed), Cochrane, Scopus, and Scielo databases for articles published between 2010 and 2021. The exclusion criteria were: systematic reviews, case reports, expert opinions; animal studies; samples of less than 10 subjects; follow-up periods of less than 36 months; smokers of minimum 10 cigarettes/day; and articles about mini-implants for orthodontic anchorage. Meta-analyses were performed to assess marginal bone loss and implant survival, success, and failure rates. Fifteen studies were included: 7 clinical trials, 3 randomized clinical trials, 3 cohort studies, and 2 case series. The total number of subjects was 773, in whom 1245 implants were placed. The survival rate for the narrow diameter implants was 97%, the success rate 96.8%, and the failure rate 3%. Marginal bone loss was 0.821 mm. All these data were evaluated at 36 months. Based on the literature, it can be considered that there is sufficient evidence to consider small diameter implants a predictable treatment option. These show favorable survival and success rates and marginal bone loss. All of them are comparable to those of standard diameter dental implants.

Carotid Occlusive Disease

Background Emergent large vessel occlusive (ELVO) stroke secondary to underlying carotid occlusive disease is frequently encountered in endovascular ischemic stroke therapy and trials. Up to 29% of all cerebral vascular accidents are attributed to severe carotid occlusive disease, and recent interventional trials have demonstrated this occurrence in 18.6–32.2% of ELVO stroke. We present a novel technique using the stent retriever guide wire to expedite angioplasty and/or stent placement for associated carotid occlusive disease during mechanical thrombectomy of ELVO stroke. This technique utilizes the “waiting time” during stent retriever integration within the thrombus as an opportunity to initiate revascularization of the cervical carotid, using the deployed stent retriever guidewire as an ad hoc rapid exchange wire while the stentriever serves as a potential surrogate distal embolic protection device. We present 23 cases using this novel endovascular approach, which we have called the single-cross technique, as the cervical lesion is only traversed once during therapy. Methods A case series of 23 consecutive patients who underwent a novel endovascular technique for treating tandem ICA origin and intracranial occlusive lesions is presented. Endpoints measured were time to re-perfusion, rates of intracranial hemorrhage and clinical outcomes (mRS at 30 and 90 days). Results Average procedure time for revascularizing both the carotid and intracranial lesions was 52 min. A symptomatic ICH rate of 9% was observed. Seventy-four percent of patients had an mRS of 0–2 at follow-up. Conclusions The single-cross technique appears to be a safe and effective option for treating tandem occlusive lesions in the setting of ELVO.

Abstract Background and study aims Endoscopic ultrasound (EUS)-guided pancreaticogastrostomy (PG) has been used as an alternative to surgery to drain pancreatic ducts for treatment of disconnected pancreatic duct syndrome (DPDS). Previous techniques involved using needle-knife cautery, bougie dilation or a stent extraction screw to allow stent passage through the gastric wall and pancreatic parenchyma, with potential for severe complications including duct leak, especially if drainage fails. A novel technique employing EUS guided puncture of the main pancreatic duct (MPD) with a 19- or a 22-gauge needle, passage of an 0.018-guidewire, dilation of the tract with a small-diameter (4 F) angioplasty balloon and placement of 3F plastic stents with the pigtail curled inside the duct as an anchor. Methods This is a retrospective case series at a single tertiary center. EUS-guided PG was considered when conventional endoscopic pancreatic duct drainage failed. Main outcomes included technical and clinic success and complications. Results Eight patients underwent PG. Indications were DPDS (n = 4), stenotic pancreaticoenteral anastomosis after Whipple procedure (n = 3) and chronic pancreatitis with dilated MPD (n = 1). Median MPD diameter was 6.75 mm [IQR 2.8 – 7.6]. Technical success was achieved in seven of eight cases (88 %); angioplasty balloon passed into the pancreatic duct in all accessed ducts. There was one asymptomatic duct leak, and no major or delayed complications, with clinical improvement (complete or partial) in five of eight (71 %). Conclusions EUS-guided PG using a small-caliber guidewire, 4F angioplasty balloon, and reverse 3F single pigtail stents offers a safe and atraumatic alternative without use of cautery.
