Outcomes of periarterial sympathectomy in patients with digital ischemia.

INTRODUCTION: Digital ischemia with subsequent severe pain and tissue loss is often difficult to treat, with no obvious guidelines or strong evidence in the literature to support a specific treatment modality. Patients who fail medical treatment remain with very limited surgical options due to the difficulty of any intervention in this "no man's land" area of the hand, as described since 1918. Extended distal periarterial sympathectomy is reported as an effective treatment option since the eighties of last century. The procedure entails large incisions and major technical difficulties. In this study, we describe a less invasive approach with very promising results and equally high success rates. MATERIALS AND METHODS: This was a prospective study. All patients with severe digital ischemia manifesting with bluish discoloration, ulceration, and/or dry gangrene who failed medical treatment underwent distal periarterial sympathectomy for the radial and ulnar arteries, with added digital sympathectomy in very severe cases. Primary endpoints were ulcer healing and improvement in pain scores assessed by Visual Analog Scale pain scoring system. Secondary endpoints included complications and amputation rates. RESULTS: This study recruited 17 patients between January 2019 and January 2020. The mean follow-up was 14.6 months. The mean age was 33.71 (±SD 13.14) years. 41% were males. 59% suffered from vasculitis, 35% of patients had dry gangrene, and 71% had ulcers. Periarterial radial and ulnar sympathectomy was performed for all cases, with digital sympathectomy for 12 fingers. We had 50% complete ulcer healing within 1 month (p = 0.031), and 100% were completely healed at 6 months (p < 0.001). Pain scores showed significant reductions at 1 (p = 0.001) and 6 months (p < 0.001) of follow-up. CONCLUSION: Distal periarterial sympathectomy demonstrates high success rates in terms of pain relief and ulcer healing in severe digital ischemia.

Short-term outcome of primary stent graft for peripheral artery aneurysm in patients with Behçet disease.

OBJECTIVE: Endovascular treatment of peripheral artery aneurysms (PAAs) in patients with Behçet disease is controversial. We report a single-institution experience of primary stent graft repair of PAAs in Behçet patients. METHODS: Behçet patients who had endovascular stent graft repair of PAAs at a single center between January 2012 and December 2018 were identified. Demographics, past medical history, cardiovascular risk profile, and perioperative details were analyzed. RESULTS: Twenty-two patients (mean age, 38 ± 7 years; 100% male) were included. The distribution of PAAs was external iliac artery in 2 (9%) patients, common femoral artery in 4 (18%) patients, superficial femoral artery in 15 (68%) patients, and above-knee popliteal artery in 1 (5%) patient. Pseudoaneurysm was diagnosed in five (23%) patients. We used antegrade access in the majority of patients (16 [73%]). Technical success was achieved in 21 (95%) patients. The mean hospital stay was 3 ± 2 days. There were no deaths or serious complications, and five (23%) patients experienced access site complications. The mean follow-up was 23 ± 11 months. The early primary and assisted primary patency rate was 91%. However, follow-up computed tomography angiography detected stent graft occlusion in six patients (27%). CONCLUSIONS: Stent graft for PAA in patients with Behçet disease had a high early patency rate and minimal morbidity. However, the complication and reintervention rates were high during follow-up, with low surgical conversion.

Conversion of Arterio-Venous Access of Hemodialysis to Arterio-Arterial Access for Treatment of Venous hypertension with Central Venous Occlusion.

This report describes conversion of arterio-venous graft or fistula to arterio-arterial vascular access as a new surgical treatment option for central venous occlusion. It starts with control of the axillary vein and the synthetic graft or superficialized vein proximally, the suture line of venous anastomosis is closed and end-to-side anastomosis of the synthetic graft or vein to the brachial artery (BA) is done, then ligation of the BA distal to the anastomosis is done. Now the blood flow is directed through synthetic graft or vein from proximal to distal BA that can be used as arterio-arterial vascular access for hemodialysis.

Ovarian vein surgical ablation versus endovascular technique for treatment of pelvic vein incompetence.

OBJECTIVE: Chronic pelvic pain in women is a disorder brought on by pelvic vein incompetence (PVI). In this prospective, randomized study, the effects of percutaneous coil embolization and surgical ovarian vein ligation and division combined with retrograde sclerotherapy were compared with regard to ovarian vein occlusion, improvement of pelvic congestion symptoms, and their influence on estradiol level after intervention. METHODS: A total of 50 patients with PVI were enrolled, with a mean age of 31.9 ± 4.7 years and a pain score of 9 (range, 0-10; from 0 [no pain] to 10 [the highest level of pain]). Both percutaneous coil embolization of ovarian veins (endovascular group) and surgical ovarian vein ablation with retrograde sclerotherapy were offered to the patients at random. RESULTS: In the open group, the pain level decreased to 2, whereas in the endovascular group, it decreased to 1 (range, 0-10). Estradiol levels were 224 (range, 9-612) in the open group and 478 (range, 18-613) in the endovascular group before the intervention, with no significant change (P = .1120). After 1 week of intervention, estradiol levels in the open group were 89 (range, 18-243) and 124 (range, 22-298) in the endovascular group, respectively, with statistical insignificance (P = .225). After 1 month of intervention, the endovascular group's estradiol level was 101 (range, 20-196) and the open group's was 89 (range, 15-190) (P = .382). After 3 months of intervention, the open group's estradiol level was 78 (range, 12-132) and the endovascular group's was 65 (range, 18-110) (P = .045). CONCLUSIONS: In addressing PVI, both methods seemed to have promising results. Nevertheless, endovascular management was more effective at decreasing estrogen levels and relieving discomfort. Three months should be the time at which estradiol levels are measured, because this is when they are at their lowest. In both the open and endovascular groups as well as in the pooled data, there was a significant association between estradiol level from before the intervention and improvement in pain scores (P = .005). Because it was linked to a lower pain score, the high preoperative estradiol level can be used to predict postintervention improvement.

Surgical management of venous aneurysms.

BACKGROUND: Venous aneurysms (VA) are often underestimated as a dangerous vascular condition that can lead to fatal complications. We have adopted a more aggressive surgical approach to treatment of venous aneurysms that seems to be safe and effective, and report herein the results of this approach. METHODS: A retrospective analysis of patients presented with VA between January 2013, and January 2018. RESULTS: We identified 13 VA in 13 patients. The mean patient age was 21.6 years (range, 7-42 years). Six patients were male (46.2%) and seven were female (53.8%). All patients presented with swellings in different areas, mostly in the neck (nine patients [69.2%]). Two patients had a short saphenous vein aneurysm complicated with paresthesia (15.3%). All patients underwent surgical correction. Tangential excision was done for noncomplicated saccular aneurysms (six patients [46.2%]), whereas ligation and excision were done for fusiform aneurysms (five patients) and two saccular aneurysms presenting with thrombosis (53.8%). No signification complications were noted. CONCLUSIONS: Surgical treatment of venous aneurysms is safe and may help to avoid possible pulmonary embolism.

Comparison of Intrapleural with Paravertebral Levobupivacaine Analgesia for Thoracoscopic Sympathectomy: A Randomized Controlled Study.

BACKGROUND: Palmar hyperhidrosis is a benign disease of excessive sweating in the palm that exceeds the physiological state. Thoracoscopic sympathectomy is an effective surgical treatment for localized hyperhidrosis. AIMS: The aim of this study was to compare paravertebral block (PVB) with intrapleural analgesia in thoracoscopic sympathectomy. SETTINGS AND DESIGN: A total of 90 patients physical status American Society of Anesthesiologists Classes I or II scheduled for arthroscopic thoracoscopic sympathectomy were enrolled in this study. SUBJECTS AND METHODS: Patients were randomly allocated into three groups; in the controlled (C) group, no regional block was performed. In the intrapleural (I) group or paravertebral (P) group using a volume of 20 ml of levobupivacaine 0.5%. The first request for analgesia postoperatively was our primary concern. Secondary outcomes included pain scores, the cumulative consumption of fentanyl during the 1st postoperative day, pulmonary functions, blood gases, and complications. STATISTICAL ANALYSIS USED: Statistical analysis was done using Statistical Package for Social Sciences (SPSS 19.0, Chicago, IL, USA). RESULTS: First request of analgesia in paravertebral group was statistically significantly longer when compared with either control or intrapleural group. In addition, total fentanyl dose was significantly higher in control group when compared with the other groups. Groups I and P showed statistically significant less pain scores, better pulmonary function, and blood gases when compared with control group. CONCLUSION: We concluded that either intrapleural or paravertebral analgesia compared with control group in thoracoscopic sympathectomy resulted in later request of analgesia, improved pain control, reduced analgesic requirements postoperatively, preservation of lung function and acid-base balance. The PVB, compared to intrapleural, had an advantage of longer and effective analgesia.
