A multicentre retrospective study of lumbar sympathectomy for plantar hyperhidrosis: satisfaction and postoperative complications.

BACKGROUND: Primary plantar hyperhidrosis has a severe impact on quality of life and conservative treatments are only effective in the short term. Thoracic sympathectomy has proven its effectiveness in the treatment of palmar hyperhidrosis, but lumbar sympathectomy for plantar hyperhidrosis remains poorly described. OBJECTIVES: To report the satisfaction of patients with primary plantar hyperhidrosis treated with mechanical lumbar sympathectomy as well as their postoperative complications. METHODS: This was a multicentre retrospective observational study of 16 patients with primary plantar hyperhidrosis, treated with mechanical lumbar sympathectomy from December 2012 to October 2022. Patients' characteristics were collected from medical records. Quality of life, postoperative satisfaction and complications were evaluated using a standardized questionnaire. RESULTS: Lumbar sympathectomy was performed on 16 patients, 14 were women and 2 were men with a total of 31 procedures. Fourteen (88%) patients were satisfied and would recommend the surgery to other patients. Compensatory hyperhidrosis occurred in 75% of patients, recurrence of hyperhidrosis in 31% and sexual dysfunction in 19%. CONCLUSIONS: Lumbar sympathectomy provides satisfying results for plantar hyperhidrosis with acceptable postoperative complications, regardless of sex. Compensatory hyperhidrosis was the most frequent complication but had no impact on patient satisfaction. In the literature, data on the risk of sexual dysfunction are reassuring and in our study only one of two men experienced transient ejaculation disorder.

Evaluation of Quality of Life after Surgical Treatment of Thoracic Outlet Syndrome.

BACKGROUND: To evaluate the quality of life of surgically treated patients for TOS. METHODS: A prospective observational study, including patients treated surgically for TOS in 2018. Two standardized questionnaires: Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and the Short-Form 12 (SF-12) were used. The SF-12 consists of a physical and mental component (PCS-SF-12 and MCS-SF-12). The questionnaires were completed during the preoperative and postoperative consultations and at 3, 6, and 12 months. RESULTS: We performed 53 interventions. The population was mostly female (n = 35, 66.0%) of 40.1 ± 10.0 years. The preoperative DASH score was 46.3 ± 19.7. It was 40.9 ± 21.7 at 6 weeks, 33.5 ± 22.7 at 3 months, 28.9 ± 22.6 at 6 months, and 21.1 ± 20 at 9 to 12 months. The improvement of DASH becomes statistically significant at 3 months (P = 0.036), 6 months (P = 0.002), and 12 months (P = 0.001). The preoperative MCS-SF-12 was 36.6 ± 9.4. It was 41.6 ± 10.9 at 6 weeks, 43.8 ± 11.1 at 3 months, 46.2 ± 11.8 at 6 months, and 51.4 ± 8 at 8 to 12 months. The improvement of MCS-SF-12 became significant at 3 months (P = 0.009), 6 months (P = 0.001), and 12 months (P = 0.001). The preoperative PCS-SF-12 was 35.5 ± 6.4. It was 37.1 ± 8.7 at 6 weeks, 39.9 ± 8.7 at 3 months, 41.6 ± 8.4 at 6 months, and 46.1 ± 8.1 to 12 months. The improvement of PCS-SF-12 became significant at 6 months (P = 0.005) and 12 months (P = 0.001). CONCLUSIONS: The surgical management of TOS allows for an improvement in quality of life in the short and medium terms.

Thoracic Outlet Syndrome: Fingertip Cannot Replace Forearm Photoplethysmography in the Evaluation of Positional Venous Outflow Impairments.

Objective: Fingertip photoplethysmography (PPG) resulting from high-pass filtered raw PPG signal is often used to record arterial pulse changes in patients with suspected thoracic outlet syndrome (TOS). Results from venous (low-pass filtered raw signal) forearm PPG (V-PPG) during the Candlestick-Prayer (Ca + Pra) maneuver were recently classified into four different patterns in patients with suspected TOS, two of which are suggestive of the presence of outflow impairment. We aimed to test the effect of probe position (fingertip vs. forearm) and of red (R) vs. infrared (IR) light wavelength on V-PPG classification and compared pattern classifications with the results of ultrasound (US). Methods: In patients with suspected TOS, we routinely performed US imaging (US + being the presence of a positional compression) and Ca + Pra tests with forearm V-PPG IR . We recruited patients for a Ca + Pra maneuver with the simultaneous fingertip and forearm V-PPG R . The correlation of each V-PPG recording to each of the published pattern profiles was calculated. Each record was classified according to the patterns for which the coefficient of correlation was the highest. Cohen's kappa test was used to determine the reliability of classification among forearm V-PPG IR , fingertip V-PPG R , and forearm V-PPG R . Results: We obtained 40 measurements from 20 patients (40.2 ± 11.3 years old, 11 males). We found 13 limbs with US + results, while V-PPG suggested the presence of venous outflow impairment in 27 and 20 limbs with forearm V-PPG IR and forearm V-PPG R , respectively. Fingertip V-PPG R provided no patterns suggesting outflow impairment. Conclusion: We found more V-PPG patterns suggesting venous outflow impairment than US + results. Probe position is essential if aiming to perform upper-limb V-PPG during the Ca + Pra maneuver in patients with suspected TOS. V-PPG during the Ca + Pra maneuver is of low cost and easy and provides reliable, recordable, and objective evidence of forearm swelling. It should be performed on the forearm (close to the elbow) with either PPG R or PPG IR but not at the fingertip level.

STABILISE Technique via a Transapical Approach to Repair Residual Type A Aortic Dissection.

The stent-assisted balloon-induced intimal disruption and relamination in aortic dissection or STABILISE concept is a novel endovascular strategy in Type A and Type B dissections. We report a case of Type A aortic dissection repair combining, first, an open thoracic aortic surgery with an elephant trunk procedure and, second, an endovascular treatment using the STABILISE technique via a combined transapical approach commonly used for transcatheter aortic valve implantation and a femoral pathway.

Arterial Digital Pulse Photoplethysmography in Patients with Suspected Thoracic Outlet Syndrome: A Study of the "Ca+Pra" Maneuver.

The level of pulse amplitude (PA) change in arterial digital pulse plethysmography (A-PPG) that should be used to diagnose thoracic outlet syndrome (TOS) is debated. We hypothesized that a modification of the Roos test (by moving the arms forward, mimicking a prayer position ("Pra")) releasing an eventual compression that occurs in the surrender/candlestick position ("Ca") would facilitate interpretation of A-PPG results. In 52 subjects, we determined the optimal PA change from rest to predict compression at imaging (ultrasonography +/- angiography) with receiver operating characteristics (ROC). "Pra"-PA was set as 100%, and PA was expressed in normalized amplitude (NA) units. Imaging found arterial compression in 23 upper limbs. The area under ROC was 0.765 ± 0.065 (p < 0.0001), resulting in a 91.4% sensitivity and a 60.9% specificity for an increase of fewer than 3 NA from rest during "Ca", while results were 17.4% and 98.8%, respectively, for the 75% PA decrease previously proposed in the literature. A-PPG during a "Ca+Pra" test provides demonstrable proof of inflow impairment and increases the sensitivity of A-PPG for the detection of arterial compression as determined by imaging. The absence of an increase in PA during the "Ca" phase of the "Ca+Pra" maneuver should be considered indicative of arterial inflow impairment.

Surgery of Renal Artery Aneurysms: A Monocentric Retrospective Study.

BACKGROUND: The aim of the study was to report the results of conventional surgery for renal artery aneurysms (RAAs) in our center. MATERIAL AND METHODS: We retrospectively reviewed the files of all the patients operated for RAAs between 2009 and 2018 in our center. We collected demographic, biological (renal function), morphological (computed tomography [CT] scan), and functional (ultrasound examination and resistance index) preoperative and postoperative data. Clinical and paraclinical operative data were examined. Results were expressed as average ± standard deviation or median and extremes. RESULTS: A total of 26 aneurysms were operated in 20 kidneys (10 right kidneys) among 19 patients, including 13 (68%) women with an average age of 55 (±12) years. Three (16%) patients presented an aneurysm in a single kidney. The discovery of the aneurysm was fortuitous in 14 (74%) patients. One patient with Marfan syndrome was operated after a postpartum rupture. The median diameter of the operated aneurysms was 22 mm (7-48), and 23 (90%) were hilar aneurysms. Arterial repair was carried out in situ in 16 (80%) kidneys. The surgery consisted of a direct arterial repair in 21 cases (81%), including 4 resections and anastomoses, 12 aneurysmorrhaphies, and 5 complex reconstructions. Four arterial replacements were carried out (one prosthetic graft, 2 femoral grafts, and one internal iliac graft). The average duration of renal clamping was 30.5 (±17.3) min. Postoperative renal function was unchanged in all the patients except for one (5.2%) who required 2 days of postoperative dialysis. The resistance index of all the operated kidneys was normal (0.66 ± 0.08) at discharge. Sixteen (70%) of the 23 aneurysms were examined, and anatomopathology concluded them to be of dysplastic origin. At 3 months, a systematic CT scan objectified the patency of 95% of the arterial reconstructions, with 3 stenoses >50%. One stenosis >80% was treated at 7 months by balloon angioplasty. Only one operated kidney presented a loss of viability of its upper pole. The mean duration of follow-up was 54 ± 35 months. By the end of the follow-up, primary and secondary patency rates evaluated by Doppler ultrasound were 90% and 95%, respectively. CONCLUSIONS: Conventional surgery generally performed in situ remains a sure and effective treatment for RAAs. This challenging surgery for a rare disease should be performed in experimented centers.

Treatment of Carotid Restenoses after Endarterectomy: A Retrospective Monocentric Study.

BACKGROUND: To compare the different techniques for the treatment of carotid restenosis after carotid artery endarterectomy (CAE). METHODS: Among 1,218 carotid surgeries carried out in our center between January 2010 and November 2017, 45 procedures were performed for carotid restenosis after CAE, including 11 by iterative conventional surgery and 34 with endovascular techniques (7 transluminal angioplasties alone [TLA], 9 carotid artery stenting [CAS], and 18 angioplasties with active balloons [drug-coated balloon {DCB}]). Perioperative data (cumulated rate of morbimortality [CRMM], duration of hospitalization) and postoperative results (survival, symptomatic restenoses > 50% or asymptomatic stenoses > 70% on ultrasound, reinterventions) were collected retrospectively and analyzed with Fisher's exact test. The long-term results were estimated according to the Kaplan-Meier estimator and were compared with the log rank test (P < 0.05 was regarded as significant). RESULTS: There was one secondary death due to a massive postoperative stroke in the endovascular (ENDO) group. No significant difference regarding CRMM (2.9%, P = 0.756) between the iterative conventional surgery (open surgery; OS) and the ENDO groups of was observed. Three hematomas were found in the OS group versus one in the ENDO group (P = 0.04). The length of hospital stay was shorter in the ENDO group (P < 0.001). No difference was found between the ENDO group and the OS group regarding the two-year survival or the survival without recurrent restenosis (86 vs. 100%, log rank = 0.804, and log rank = 0.114). There were 5 restenoses >70% and two reinterventions in the ENDO group (P > 0.05). The comparison of the different endovascular techniques did not show significant differences regarding the CRMM, the one-year overall survival, the survival without recurrent restenosis, or the survival without reintervention (89% in the DCB and CAS groups vs. 100% in the percutaneous transluminal angioplasty [PTA] group, log rank = 0.286; 87% in the DCB group vs. 100% in the PTA and CAS groups, log rank = 0.137; and 94% in the DCB group vs. 100% in the PTA and CAS groups, log rank = 0.585, respectively). CONCLUSIONS: In our experience, endovascular procedures are equivalent to iterative conventional surgery for the treatment of carotid restenoses in terms of major complications, news restenoses, or survival with less hematoma and a shorter duration of hospitalization. We however could not identify the best endovascular strategy in this indication, and a controlled study comparing the various endovascular strategies is proposed.

High prevalence of exercise-induced ischemia in the asymptomatic limb of patients with apparently strictly unilateral symptoms and unilateral peripheral artery disease.

BACKGROUND:: The prevalence of exercise-induced ischemia in the asymptomatic limb of patients with unilateral claudication based on history and treadmill evaluation, and with unilateral ipsilateral peripheral artery disease (i.e ankle-to-brachial systolic pressure index <0.90) is unknown. METHODS:: We detected exercise-induced ischemia in the asymptomatic limb of patients with apparently unilateral claudication. Among 6059 exercise-oximetry tests performed in 3407 nondiabetic and 961 diabetic patients. We estimated the intensity of ischemia in the both limb (buttocks and calves) using the lowest minimum value of the decrease from rest of oxygen pressure (DROP; limb changes minus chest changes from rest), with significant ischemia defined as DROP lower than -15 mmHg. RESULTS:: We found 152 tests performed in 142 nondiabetic patients and 40 tests performed in 38 diabetic patients. The asymptomatic limb showed significant ischemia in 46.7% and 37.5% of the tests. Strictly unilateral exercise-induced claudication with apparently unilateral peripheral artery disease was rare (<4% of all tests). However, among these highly selected tests, significant ischemia was found in the asymptomatic limb in more than one-third of cases. CONCLUSION:: The asymptomatic limb of patients with peripheral artery disease should not be considered a normal limb.

Frequency of the Pectoralis Minor Compression Syndrome in Patients Treated for Thoracic Outlet Syndrome.

BACKGROUND: Pectoralis minor compression syndrome (PMCS) is a compression of the neurovascular structures in the subpectoral tunnel and remains underestimated in the management of patients with thoracic outlet syndrome (TOS). Its underdiagnosis may be responsible for incomplete or failed treatment. The aim of the study was to evaluate the frequency of PMCS in our experience. METHODS: We retrospectively reviewed all patients treated for TOS in our department. We selected those in whom PMCS was diagnosed with a systematic dynamic arteriography. Surgery was performed using the Roos axillary approach when a first rib resection was associated or an elective approach when a first rib resection was not associated. RESULTS: From January 2004 to December 2014, 374 surgeries for TOS were performed in 279 patients, which included 90 men (sex ratio = 0.48) with a mean age of 40.1 ± 10 years old. Among these patients, 63 (22.5%) underwent 82 interventions (21.9%) for PMCS, including 26 men (sex ratio = 0.70, P < 0.05) with a mean age of 37.9 ± 9.4 years old. Tenotomy of the pectoralis minor muscle was performed using axillary approach if it was associated with a first rib resection in 74 cases (90.2%) or through an elective approach in 8 cases (9.8%) if it was isolated. Four (4.9%) postoperative complications were found (1 hematoma [1.2%], 1 hemothorax [1.2%], 1 scapula alata [1.2%], and 1 subclavian vein thrombosis [1.2%]), all after an axillary approach. In 63 cases (79.7%), preoperative symptoms were resolved. In 14 cases (17.7%), symptom resolution was incomplete, and 2 patients (2.6%) had recurrent symptoms. CONCLUSIONS: Evaluation of PMCS in TOS is justified by its frequency and the simplicity and low morbidity of the surgical procedure.

Evaluation of the Vascular Surgical Complications of Renal Transplantation.

BACKGROUND: Renal transplantation is the treatment of choice of end-stage renal failure. However, vascular surgical complications can compromise the functional prognosis of the transplant or even be life threatening in the short term. Since few data are available in the literature, the objective of this study was to evaluate the vascular surgical complications of renal transplantation. METHODS: In a retrospective and monocentric study, the records of all the patients receiving a kidney transplant between January 2008 and December 2014 were reviewed. The demographic data and the follow-up of the patients who presented a vascular surgical complication in relation to their transplant were collected. Minor, intermediate, or major vascular complications were defined according to the need for monitoring, reoperation, or the risk of transplant loss or a life-threatening situation. Predictive factors of vascular complications were also looked for. RESULTS: Mean age was 50.9 ± 15.0 years, and 312 kidney transplants were carried out (205 men). Fifty vascular surgical complications (16.0%) were found. Among them, 23 vascular complications (7.4%) were major, including 6 (1.9%) which required transplantectomy, after 4 arterial thromboses (1.3%), 1 early venous thrombosis (0.3%), and 1 injury of the inferior vena cava (0.3%). Twelve complications (3.8%) were minor. Surgical revision was necessary in 76% of the vascular complications (n = 38). The average follow-up of the transplanted population was 37.4 ± 24.0 month, 268 kidney transplants (85.8%) were functional and 21 patients (6.7%) returned to dialysis. Surgical complications were more frequent when the recipient had hypertension (P = 0.02, OR = 2.5; 95% CI [1.1-6.1]), in case of right kidney transplant (P = 0.0004, OR = 3.1; 95% CI [1.6-5.8]) and when the kidney hilum consisted of at least arteries (P = 0.02, OR = 10.0; 95% CI [1.3-34]). Male gender (P = 0.03, OR = 0.5; 95% CI [0.3-0.9]) as well as the choice of the common iliac arterial (P = 0.001, OR = 0.4; 95% IC [0.2-0.7]) and venous (P = 0.002, OR = 0.3; 95% IC [0.2-0.8]) axes to carry out the vascular anastomoses appeared as protective factors. CONCLUSIONS: The vascular surgical complications of kidney transplantation, especially thromboses, can be serious and lead to transplant loss. The expertise of vascular surgeons finds its place here and makes it possible to maintain low rates of vascular complications and loss of transplants.

Endovascular treatment of iatrogenic aortic graft injury after sternal puncture.

We report the case of a 71-year old woman who had previously undergone supra-aortic trunk transposition via a median sternotomy, along with endovascular thoracic aortic stent-graft repair. During the diagnostic sternal puncture for a recently discovered acute lymphoblastic leukaemia, an accidental graft injury occurred. For this patient, who was not a surgical candidate, endovascular treatment with a covered stent (endograft) was performed, with uneventful postoperative follow-up. This case report illustrates the limitations of sternal puncture in patients with a previous sternotomy, and discusses the possibility of endovascular treatment in the event of aortic graft injury, given easy accessibility and favourable aortic neck anatomy.

Total endovascular repair of an aortic arch aneurysm using an externalized transseptal guidewire technique.

Total endovascular treatment of complex ascending and arch disease remains extremely challenging with difficulties provided by the curvature of the arch, the variable anatomy of the great vessels, the proximity of the coronary ostia, potential damage to the aortic valve, and ventricle and instability during deployment. Given this background, reports of the total endovascular treatment of aortic arch are sparse. We describe one challenging case using an arch branched endograft that was safely advanced and precisely positioned into the ascending aorta using an externalized transseptal guide wire technique.
