Coronary subclavian steal syndrome due to thrombosis of the left subclavian artery aneurysm: a case report.

Background: Coronary subclavian steal syndrome (CSSS) is an often easily overlooked cause of angina that may occur after a coronary artery bypass graft (CABG) procedure. The onset of CSSS several years after coronary revascularization has been described in case reports, and in the few retrospective reviews that compare the endovascular approach with surgical treatment. Subclavian stenosis can naturally coincide with coronary artery disease and may already be present during the initial CABG. Case summary: A 59-year-old male with a history of three-vessel disease who had a left internal mammary artery (LIMA) bypass graft, exhibited a gradual worsening of angina that coincided with numbness and impaired function of the left fingers, hand, and arm. Myocardial perfusion imaging showed reversible ischaemia, and coronary angiography suggested a thrombotic lesion proximal to the LIMA ostium. Calcified and partially thrombosed proximal left subclavian artery (LSA) aneurysm was visualized using computed tomography imaging, whereas Doppler ultrasound revealed a partially reversed vertebral flow. The lowest risk treatment was a bypass between the left common carotid artery and the LSA. The procedure was immediately successful, with cessation of symptoms and a favourable medium-term outcome. Discussion: As no guidelines exist for such cases, the importance of multidisciplinary co-operation in diagnostics and devising a treatment plan is underlined. Moreover, screening for subclavian artery stenosis in CABG candidates should be warranted as part of the initial preoperative assessment.

Compensated and non-compensated patient injury claims in internal carotid artery interventions in Finland, 2004-2017.

OBJECTIVES: Analysis of patient injuries offers possibilities for improving quality in patient care. The aim of this study was to identify errors and adverse events leading to patient injuries in the treatment of internal carotid artery stenosis (ICAS). METHODS: A retrospective analysis was performed on data from Finnish patient injury claims and patient insurance center decisions in the treatment of ICAS, 2004-2017. Contributing factors to injury were identified and evaluated. RESULTS: During the 14-year study period, 42 patient injury claims involving ICAS treatment were closed in Finland. One claim involved carotid artery stenting, and the other operations were carotid artery endarterectomies. Nine of the claims were compensated (seven for operations and two for evaluations). Fully trained vascular surgeons had carried out all the operations and evaluations. Stroke was the most common complaint in the claims (n = 12). Six of the compensated patients were symptomatic prior to the interventions. Injuries were related to errors in decision-making and patient selection in two cases. Four patients received compensation for nerve injury and three for stroke. No deaths were compensated as patient injuries. Most negative claim decisions were related to the injury having been unavoidable. CONCLUSION: Compensated patient injuries involving the treatment of ICAS are rare but often serious and mostly involve open surgery. Patient injury claims provide a valuable source of information for recognizing errors in care and offer possibilities to improve patient safety.

Major Lower Limb Amputations and Amputees in an Aging Population in Southwest Finland 2007-2017.

Purpose: The aim of the present study was to describe and analyze changes in the incidences of lower extremity amputations (LEAs), patient characteristics, vascular history of amputees and survival in Southwest Finland. Patients and Methods: This is a retrospective patient study in the Hospital District of Southwest Finland. All consecutive patients with atherosclerosis and diabetes-caused LEA, between 1st January 2007 and 31st December 2017, were included. The annual incidences of major LEA patients were statistically standardized. Patients' diagnoses, functional status, previous revascularizations and minor amputations were recorded, and survival was analyzed. Results: During the 11-year-period major LEAs were performed on 891 patients, 118 (13.2%) were urgent operations. The overall incidence of major LEA was 17.2/100 000 and was age-dependent (3.1 for ≤64 years, 34.3 for 65-74 years, 81.5 for 75-84 years, 216 for ≥85 years). A decrease in incidence was detected in the <65 year-age-group (incidence 4.98 in 2007 and 1.88 in 2017; p = 0.0018). Among older age groups, there was no significant change. Half (50.6%) of all amputees were diabetics. Altogether, 472 patients (53.0%) had a history of revascularization before LEA. 80.1% of index amputations were transfemoral and 19.9% transtibial. Re-surgery was performed on 94 (10.5%) patients. The 1-, 3- and 5-year overall survival were 56%, 30%, and 18%, respectively. Conclusion: Our results suggest that in an aging population, despite good availability of vascular services, a significant number of patients are not fit for active revascularization, and LEA is the only feasible treatment for critical limb ischemia.

Compensated Patient Injuries in the Treatment of Abdominal Aortic and Iliac Artery Aneurysms in Finland: A Nationwide Patient Insurance Registry Study.

OBJECTIVES: Patient injury claims data and insurance records provide detailed information on patient injuries. This study aimed to identify the errors and adverse events that led to patient injuries in vascular surgery for the treatments of abdominal aortic aneurysms (AAA) and iliac artery aneurysms (IAA) in Finland. The study also assessed the severity and preventability of the injuries. MATERIALS AND METHODS: A retrospective analysis of Finnish Patient Insurance Centre's insurance charts of compensated patient injuries in the treatment of AAA and IAA. Records of all compensated patient injury claims involving AAA and IAA between 2004 and 2017 inclusive were reviewed. Contributing factors to injury were identified and classified. The injuries were assessed for their preventability by using the WHO Surgical Safety Checklist correctly. The degree of harm was graded by Clavien-Dindo classification. RESULTS: Twenty-six patient injury incidents were identified in the treatment of 23 patients. Typical injuries involved delays in diagnosis or treatment, errors in surgical technique or injuries to adjacent anatomic organs. Three (13.0%) patients died due to patient injury. Two deaths were caused by delays in diagnosis of ruptured abdominal aortic aneurysm (RAAA) and the third death was due to missed diagnosis of post-operative myocardial infarction. Retained foreign material caused injuries to two (8.7%) patients. One (4.3%) patient had a severe postoperative infection. Three (13.0%) patients experienced an injury to an adjacent organ. One patient had a bilateral and another a unilateral above-the-knee amputation due to patient injury. Three injuries were considered preventable. Most harms were grade IIIb Clavien-Dindo classification in which injured patients required a surgical intervention under general anesthesia. CONCLUSIONS: Compensated patient injuries involving the treatment of AAA and IAA are rare, but are often serious. Injuries were identified during all stages of care. Most injuries involved open surgical procedures.

Patient injuries in the treatment of superficial venous insufficiency registered in Finland between 2004 and 2017.

OBJECTIVES: This study aimed to identify the unintended incidents that led to patient injuries (PIs) in the treatment of superficial venous insufficiency (SVI). METHODS: PI claims filed with the Finnish Patient Insurance Centre between 2004 and 2017 involving SVI were reviewed. Factors contributing to PI were identified and classified. RESULTS: Eighteen (13.2%) of 136 compensated PIs in the specialty of vascular surgery were related to SVI. Only 4.7% of 383 SVI claims were compensated. The incidence of PIs was 9.9 per 100 000 patients. Fifteen patients had open surgery (83.3%) and three (16.7%) endovenous treatment. Two (11.1%) patients had necrotising fasciitis, four (22.1%) had deep vein injuries and two (11.1%) had a permanent nerve injury. Two (11.1%) patients had retained endovenous material that required surgical removal. CONCLUSIONS: PIs were identifiable during all stages of care, perioperative injuries related to open surgery being the most common.

Vein Harvest Wound Healing after Bypass Surgery for Critical Limb Ischemia.

BACKGROUND: Lower-limb revascularization surgery, especially when performed using the great saphenous vein, predisposes patients to major surgical trauma on initially ischemic tissue. Vein harvest wounds (VHWs) after infrainguinal revascularization heal slowly. This study's aim was to assess the factors associated with VHW healing after infrainquinal bypass surgery for critical limb ischemia (CLI). METHODS: A retrospective patient record study was conducted. All patients with CLI who underwent infrainguinal bypass surgery with autologous vein graft between January 1, 2015, and December 31, 2017, in the Turku University Hospital, were included. Follow-up data were collected until February 28, 2018. The following data was collected from the patient files; risk factors, ankle-brachial indices (ABIs), systolic toe pressures (STPs), the presence of an ischemic ulcer, VHW dehiscence, and the time when the VHW was completely healed. Procedures with outflow vessels at either popliteal or tibial artery were analyzed separately. Descriptive and univariate statistical analyses were performed. RESULTS: Altogether, 195 patients were operated on for CLI, of whom 133 (68.2%) patients had ischemic ulcers. The mean follow-up time was 535.0 days (range 3.0-1143.0 days). The mean ABI improvement was 0.49 (P = 0.00), and STP improvement, 39.9 mm Hg (P = 0.00). The median time taken when VHW was healed was 48.0 days (95% confidence interval [CI], 39.4-56.6) in patients without ischemic ulcers and 82.0 days (95% CI, 59.7-104.3) in patients with ischemic ulcers, P = 0.03. VHW in patients who underwent popliteal artery bypass (62 days, 95% CI, 12.9-93.0) healed faster than VHW in those who underwent tibial artery bypass (132 days, 95% CI, 48.0-93.0), P = 0.02. Risk factors and the preoperative or postoperative ABIs or STPs had no effect on VHW healing time. CONCLUSIONS: VHW healing was remarkably slower after revascularization surgery in patients with an ischemic foot ulcer than in those without ischemic ulcers.

Patient Injuries in Treatment of Peripheral Arterial Disease in Finland: Review of National Patient Insurance Charts.

BACKGROUND: Patient injury claim data and insurance records constitute detailed sources of information on patient injuries and their contributing or causal factors. This study aimed to identify the unintended incidents that lead to patient injuries in vascular surgery in the treatment of peripheral arterial disease (PAD) in Finland. METHODS: The records of all accepted patient injury claims involving PAD between 2004 and 2017 inclusive were obtained from the nationwide Finnish Patient Insurance Centre registry and were reviewed. Factors contributing to injury were classified by patient careflow. RESULTS: Sixty-nine patient injury incidents were identified in 60 treated patients with PAD. Sixteen injuries (23.2%) were related to outpatient or preoperative care. Twenty-seven injuries (39.1%) were caused by incidents in performing open or endovascular procedures, and 26 injuries (37.7%) were related to postoperative care. Delay in treatment affected 11 (18.3%) patients. Incidents involving surgical technique were identified in the treatment of 13 (21.7%) patients. Retained foreign material caused injuries to four (6.7%) patients. Five (8.3%) patients suffered from postoperative hemorrhage and eleven (18.3%) from infection damage. Delay in treatment resulted in two major amputations. Technical problems in bypass operations led to the loss of the bypass graft and to reoperation. Three nerve injuries led to permanent disability. One (1.7%) patient died because of fatal postoperative bleeding after being discharged from the hospital. CONCLUSIONS: Compensated patient injuries in the treatment of PAD are rare. Injuries occur during all stages of care and are caused by both surgical system procedural failures and common complications.

Changes in rates of vascular procedure types and lower extremity amputations in Finland for 2007-2017 inclusive, a population cohort study of 69,523 revascularizations.

INTRODUCTION: Since 2000 the numbers of both open and endovascular revascularization procedures have increased. Despite these increases, the number of major lower extremity amputations (LEAs) has remained relatively constant. The aim of the present study was to assess the number of vascular procedures in relation to the frequency of major LEAs in Finland. METHODS: The Finnish National Institute for Health and Welfare (THL) administers a national registry of all procedures conducted by official healthcare providers in Finland. Data regarding all revascularization procedures and major LEAs between 2007 and 2017 inclusive, were collected from the THL registry. The rates of both open and endovascular procedures were analyzed. RESULTS: A total of 69,523 revascularization procedures were registered over the 11-year period. Of all revascularizations, 22.6% were endovascular in 2007, which rose to 60.5% in 2017. The annual rates of vascular procedures per 100,000 inhabitants increased from 66 in 2007 to 172 in 2017 (increase 10 procedures per year, 95% CI 8.6-12.3, P < 0.01) There was a significant increase (by 141 per year, 95% CI 110-174, P < 0.01) for open revascularizations (2705 operations in 2007, 3992 operations in 2017) and (by 491 per year, 95% CI 433-550, P < 0.01) for endovascular revascularizations (791 in 2007-5514 in 2017). Open aorto-iliac segment revascularization decreased, whereas the numbers of procedures increased for all other arterial segments. The overall frequency of amputations was 18-20 per 100,000. The frequency of amputations in the subpopulation over 65 years old decreased from 93 in 2007 to 72 in 2017 (P < 0.01). CONCLUSION: The present study demonstrated increases in vascular surgery procedures over the 11-year study-period. The increase was greatest for endovascular procedures. During the same period, there was a significant decrease in the frequency of major LEAs in the >65-year-old subpopulation.

Endovascular treatment of extradural internal carotid artery aneurysm with a flow diverter stent.

Extradural internal carotid artery aneurysms are rare and the indications for treatment are not well defined. We report successful management of two high extradural internal carotid artery aneurysms treated with flow diverter stents. The endovascular repair of extradural internal carotid artery aneurysms is effective because with surgical treatment there is always the possibility of cranial nerve injury.

Patient injuries in pediatric otorhinolaryngology.

OBJECTIVES: Patient injuries in children can have lifelong effects on the patient and a marked impact on the whole family. The aim of this study was to identify the errors and incidents leading to patient injuries in pediatric otorhinolaryngology (ORL) by evaluating accepted patient injury claims. METHODS: The records of all accepted patient injury claims in ORL between 2001 and 2011 were searched from the nationwide Patient Insurance Centre registry. Pediatric injuries were reviewed and evaluated in detail, and factors contributing to injury were identified. RESULTS: In the 10-year study period, 17 (7.6%) of the 223 patient injuries occurred in children, and of these, 15 (88%) were considered operative care. The median age of the patients was 8 years (range 3-16 years). All operations were performed as daytime elective surgery and by a fully trained specialist in 93% of the cases. One-half of the cases were routine surgeries for common ORL diseases. The most common incidences were incomplete surgery, retained gauze or foreign body, injury to adjacent anatomic structure, and insufficient charts or instructions (each occurred in 3 cases). The most frequent consequence was burn (n = 4). One child died because of post-tonsillectomy hemorrhage. CONCLUSIONS: Patient injuries in pediatric ORL are strongly related to surgery. Most injuries occurred after routine operations by a fully trained specialist. Clinicians should be aware of the most likely scenarios resulting in claims.

Intra-Dermal Absorbable Suture in the Groin Incision Associated with Less Groin Surgical Site Infections than Trans-Dermal Sutures in Vascular Surgical Patients.

BACKGROUND: The groin surgical site is frequently infected in vascular surgical procedures. Our aim was to evaluate the relation of skin closure methods and groin incision infection after vascular operations involving femoral artery exposure. METHODS: In this retrospective patient record study, patient files of all consecutive patients admitted for a vascular procedure to the Turku University Hospital Department of Vascular Surgery during 2015-2016 were evaluated. Patients with an isolated groin surgical site because of femoral artery exposure (256) were included in the study. Patient demographics, details of the operations, and follow-up data were collected from the electronic patient data record. Statistical analyses were performed using a multi-variable model. RESULTS: Altogether, 330 groin incisions were performed for 256 patients. Of all incisions, 262 (79.4%) were closed using intra-dermal absorbable suture; trans-dermal sutures were used in 68 (20.6%) incisions. Groin infections occurred in 24 (9.2%) patients after skin closure with intra-dermal absorbable suture and in 17 (25.0%) cases after trans-dermal sutures. Incisions that were closed using trans-dermal sutures were 3.5 times as likely to have an infection as those closed using intra-dermal sutures (odds ratio 3.5, confidence interval 95% 1.6 to 7.6, p = 0.002). CONCLUSION: Present data suggest that groin incision closure with intra-dermal absorbable suture is associated with groin incision infections compared with those incisions closed with trans-dermal sutures.

Iatrogenic patient injuries in otology during a 10-year period: review of national patient insurance charts.

OBJECTIVE: To assess patient injury characteristics and contributing factors in otology. METHODS: Data on the accepted patient-injury claims involving otorhinolaryngology (ORL), closed between 2001 and 2011, from the Finnish Patient Insurance Centre registry was retrieved. We included all injuries concerning otology, with evaluation and classification of their causes and types. RESULTS: During the 10-year study period, a total of 44 claims were accepted as compensated patient injuries in otology. From a total of 233 patient injuries in all ORL, this amounted to 19%. In outpatient care, occurred 12 (27%) injuries and in surgical procedures 32 (73%). Five (11%) patients were children. Errors in surgical technique were identified as the primary cause of the injury in 22 (69%) operation-related cases. Failure to remove all auricular tampons or packing in postoperative control was a contributing factor in 4 (13%) injuries, a facial nerve was damaged in 9 (28%) operations, and in 12 (38%) patients, the injury resulted in severe hearing loss or deafness. Six patients (21%) needed one or more re-operations related to the injury, of which two were due to an incomplete primary operation. CONCLUSION: Typical compensated patient injuries in operative otology resulted from common complications of common operations in high volume centres.

WHO Surgical Safety Checklist in otorhinolaryngology-head and neck surgery: specialty-related aspects of check items.

CONCLUSION: The WHO surgical checklist is well suited to otorhinolaryngology-head and neck surgery (ORL-HNS) and the users are satisfied with its content. OBJECTIVES: Use of the checklist will improve safety in operating rooms (ORs). The checklist has been taken into use in ORL-HNS, and preliminary experiences are promising. However, the checklist must be specific to the specialty in which it is used. The aim of this study was to evaluate the utility of the check items for ORL-HNS operations, with special reference to outpatient surgery. METHODS: The questionnaire study for the OR personnel was conducted at a tertiary academic hospital. Every item on the WHO checklist was evaluated and responders could provide freehand comments on the subject. RESULTS: In all, 101 responses were received from OR staff; the response rate was 95.3%. The users were mainly satisfied with the checklist's content for ORL-HNS operations. Mean scores of the importance of check items varied from 4.08 to 4.89 on a five-point scale. The item 'Allergy' had the highest score and 'Team members introduced' the lowest. A need to modify the checklist for in-hospital patients did not emerge. However, a more compact checklist for outpatient surgery carried out under local anaesthesia was suggested.

Clinical outcome of reconstruction of the lateral oropharyngeal wall with an anterolateral thigh free flap.

The anterolateral thigh (ALT) free flap is widely used for various reconstructions in the head and neck. However, its use in the oropharynx has not been widely evaluated, so we have reviewed our experience. We retrospectively reviewed the medical records of 28 patients with oropharyngeal cancer, who were treated with immediate reconstruction with an ALT free flap after excision. We recorded history, stage of tumour, course of operation, postoperative period, oncological treatment, clinical outcome, and follow-up. The mean age of the patients was 61 years (range 44-83). Ten of the patients had clinically relevant coexisting conditions. Most of the patients had T3-4 tumours and involved neck nodes. The operations included resection of the tumour, neck dissection, and reconstruction of the oropharynx with an ALT free flap. All donor sites were closed primarily. Eight patients (29%) developed early local complications that required reoperation. Ten patients (36%) had postoperative cardiopulmonary problems. Twenty-seven flaps succeeded; one was lost. There were no other complications or late problems of the donor site except one seroma. Twenty-one patients were given postoperative radiotherapy. After the mean follow-up period of 40 months (range 13-68) 20 patients (71%) were disease-free. Three patients required a permanent gastrostomy and one a permanent tracheostomy. We conclude that the ALT free flap can be used successfully for reconstruction of a lateral oropharyngeal defect with manageable postoperative morbidity.
