Cilioretinal Artery Branch Avulsion Secondary to Surgical Embolectomy: Management and Outcome.

ABSTRACT: We report the trans-operative approach and short-term outcome of a patient who suffered a traumatic avulsion of the cilioretinal artery branch during the surgical management of a cilioretinal arterial branch occlusion (CRABO) with intraocular embolectomy. A patient with acute CRABO underwent a pars plana vitrectomy with in situ embolectomy. The blocked artery was incised using 25 gauge vertical scissors, and embolus manipulation was done using microsurgical forceps. During embolus extraction, the occluded cilioretinal artery and its branch were inadvertently avulsed and torn with subsequent intense bleeding. Laser and endodiathermy were used for acute hemostasis. The maneuvers created an unintended retinochoroidal anastomosis. Visual field improvement was noted 3 months after the surgery. In the event of a complicated surgical embolectomy with the avulsion of the artery, the formation of a retinochoroidal anastomosis and reperfusion of the occluded may occur along with the improvement of visual fields in some cases.

Project description:BackgroundRectus femoris injuries are common among athletes, especially in kicking sports such as soccer; however, proximal rectus femoris avulsions in athletes are a relatively rare entity.Purpose/hypothesisThe purpose of this study was to describe and report the results of an original technique of surgical excision of the proximal tendon remnant followed by a muscular suture repair. Our hypothesis was that this technique limits the risk of recurrence in high-level athletes and allows for rapid recovery without loss of quadriceps strength.Study designCase series; Level of evidence, 4.MethodsOur retrospective series included 5 players aged 31.8 ± 3.9 years with acute proximal rectus femoris avulsion injuries who underwent a surgical resection of the proximal tendon between March 2012 and June 2014. Four of these players had recurrent rectus femoris injuries in the 9 months before surgery, while 1 player had surgery after a first injury. Mean follow-up was 18.2 ± 12.6 months, and minimum follow-up was 9 months. We analyzed the age, sex distribution, physical examination outcomes, type and mechanism of injury, diagnosis, treatment and complications during surgery, postoperative follow-up, and time to return to play. The Lower Extremity Functional Scale (LEFS) and Marx scores were obtained at 3-month follow-up, and isokinetic tests were performed before return to sports. A telephone interview was completed to determine the presence of recurrence at an average follow-up of 18.2 months.ResultsAt 3-month follow-up, all patients had Marx activity scores of 16 and LEFS scores of 80. Return to the previous level of play occurred at a mean of 15.8 ± 2.6 weeks after surgery, and none of the athletes suffered a recurrence. Isokinetic test results were comparable between both sides.ConclusionThe surgical treatment of proximal rectus femoris avulsions, consisting of resection of the tendinous part of the muscle, is a reliable and safe technique allowing a fast recovery in professional athletes.

Project description:BackgroundRenovascular hypertension (RVH) associated with renal artery and abdominal aortic narrowings is the third most common cause of pediatric hypertension. Untreated children may experience major cardiopulmonary complications, stroke, renal failure, and death. The impetus of this study was to describe the increasingly complex surgical practice for such patients with an emphasis on anatomic phenotype and contemporary outcomes after surgical management as a means of identifying those factors responsible for persistent or recurrent hypertension necessitating reoperation.MethodsA retrospective analysis was performed of consecutive pediatric patients with RVH undergoing open surgical procedures at the University of Michigan from 1991 to 2017. Anatomic phenotype and patient risk factors were analyzed to predict outcomes of blood pressure control and the need for secondary operations using ordered and binomial logistic multinomial regression models, respectively.ResultsThere were 169 children (76 girls, 93 boys) who underwent primary index operations at a median age of 8.3 years; 31 children (18%) had neurofibromatosis type 1, 76 (45%) had abdominal aortic coarctations, and 28 (17%) had a single functioning kidney. Before treatment at the University of Michigan, 51 children experienced failed previous open operations (15) or endovascular interventions (36) for RVH at other institutions. Primary surgical interventions (342) included main renal artery (136) and segmental renal artery (10) aortic reimplantation, renal artery bypass (55), segmental renal artery embolization (10), renal artery patch angioplasty (8), resection with reanastomosis (4), and partial or total nephrectomy (25). Non-renal artery procedures included patch aortoplasty (32), aortoaortic bypass (32), and splanchnic arterial revascularization (30). Nine patients required reoperation in the early postoperative period. During a mean follow-up of 49 months, secondary interventions were required in 35 children (21%), including both open surgical (37) and endovascular (14) interventions. Remedial intervention to preserve primary renal artery patency or a nephrectomy if such was impossible was required in 22 children (13%). The remaining secondary procedures were performed to treat previously untreated disease that became clinically evident during follow-up. Age at operation and abdominal aortic coarctation were independent predictors for reoperation. The overall experience revealed hypertension to be cured in 74 children (44%), improved in 78 (46%), and unchanged in 17 (10%). Children undergoing remedial operations were less likely (33%) to be cured of hypertension. There was no perioperative death or renal insufficiency requiring dialysis after either primary or secondary interventions.ConclusionsContemporary surgical treatment of pediatric RVH provides a sustainable overall benefit to 90% of children. Interventions in the very young (<3 years) and concurrent abdominal aortic coarctation increase the likelihood of reoperation. Patients undergoing remedial surgery after earlier operative failures are less likely to be cured of hypertension. Judicious postoperative surveillance is imperative in children surgically treated for RVH.

Project description:ImportanceA hemodynamic role in the pathogenesis of age-related macular degeneration (AMD) has been proposed, but to our knowledge, an association between retinal vasculature and late AMD has not been investigated.ObjectiveTo determine whether the presence and location of a cilioretinal artery may be associated with the risk of late AMD in the Age-Related Eye Disease Study (AREDS).Design, setting, and participantsRetrospective analysis of prospective, randomized clinical trial data from 3647 AREDS participants. Fundus photographs of AREDS participants were reviewed by 2 masked graders for the presence or absence of a cilioretinal artery and whether any branch extended within 500 μm of the central macula. Multivariate regressions were used to determine the association of the cilioretinal artery and vessel location, adjusted for age, sex, and smoking status, with the prevalence of choroidal neovascularization (CNV) or central geographic atrophy (CGA) and AMD severity score for eyes at randomization and progression at 5 years.Main outcomes and measuresAssociation of cilioretinal artery with prevalence and 5-year incidence of CNV or CGA.ResultsAmong AREDS participants analyzed, mean (SD) age was 69.0 (5.0) years, with 56.3% female, 46.6% former smokers, and 6.9% current smokers. A total of 26.9% of patients had a cilioretinal artery in 1 eye, and 8.4% had the vessel bilaterally. At randomization, eyes with a cilioretinal artery had a lower prevalence of CNV (5.0% vs 7.6%; OR, 0.66; 95% CI, 0.51-0.85; P = .001) but no difference in CGA (1.1% vs 0.8%; OR, 1.33; 95% CI, 0.76-2.32; P = .31). In eyes without late AMD, those with a cilioretinal artery also had a lower mean (SD) AMD severity score (3.00 [2.35] vs 3.19 [2.40]; P = .02). At 5 years, eyes at risk with a cilioretinal artery had lower rates of progression to CNV (4.1% vs 5.5%; OR, 0.75; 95% CI, 0.56-1.00; P = .05) but no difference in developing CGA (2.2% vs 2.7%; OR, 0.83; 95% CI, 0.56-1.23; P = .35) or change in AMD severity score (0.65 [1.55] vs 0.73 [1.70]; P = .11). In patients with a unilateral cilioretinal artery, eyes with the vessel showed a lower prevalence of CNV than fellow eyes (4.7% vs 7.2%; P = .01).Conclusions and relevanceThe presence of a cilioretinal artery is associated with a lower risk of developing CNV, but not CGA, suggesting a possible retinal hemodynamic contribution to the pathogenesis of neovascular AMD.Trial registrationClinicalTrials.gov Identifier: NCT00000145.
