Asia-Pacific Consensus Statement on the Management of Peripheral Artery Disease: A Report from the Asian Pacific Society of Atherosclerosis and Vascular Disease Asia-Pacific Peripheral Artery Disease Consensus Statement Project Committee.

BACKGROUND: Peripheral artery disease (PAD) is the most underdiagnosed, underestimated and undertreated of the atherosclerotic vascular diseases despite its poor prognosis. There may be racial or contextual differences in the Asia-Pacific region as to epidemiology, availability of diagnostic and therapeutic modalities, and even patient treatment response. The Asian Pacific Society of Atherosclerosis and Vascular Diseases (APSAVD) thus coordinated the development of an Asia-Pacific Consensus Statement (APCS) on the Management of PAD. OBJECTIVES: The APSAVD aimed to accomplish the following: 1) determine the applicability of the 2016 AHA/ACC guidelines on the Management of Patients with Lower Extremity Peripheral Artery Disease to the Asia-Pacific region; 2) review Asia-Pacific literature; and 3) increase the awareness of PAD. METHODOLOGY: A Steering Committee was organized to oversee development of the APCS, appoint a Technical Working Group (TWG) and Consensus Panel (CP). The TWG appraised the relevance of the 2016 AHA/ACC PAD Guideline and proposed recommendations which were reviewed by the CP using a modified Delphi technique. RESULTS: A total of 91 recommendations were generated covering history and physical examination, diagnosis, and treatment of PAD-3 new recommendations, 31 adaptations and 57 adopted statements. This Asia-Pacific Consensus Statement on the Management of PAD constitutes the first for the Asia-Pacific Region. It is intended for use by health practitioners involved in preventing, diagnosing and treating patients with PAD and ultimately the patients and their families themselves.

Masson's Hemangioma of Proximal Radial Artery.

Tumour like vascular lesions are rare. Here we report a rare case of tumor like vascular lesion from the radial artery. A pulsatile swelling in the forearm is usually diagnosed as a case of Aneurysm, AV fistula or highly vascular tumor. A middle aged man came to us with a painless pulsatile swelling on the lateral aspect of proximal right forearm. The ultrasound scan reported it as case of vascular tumour. Angiogram showed abnormal vascular channels, connected to the aneurysmal dialation of the proximal radial artery. Histopthological examination confirmed it as Masson's hemangioma after excision. This is a benign condition and complete excision is curative.

Venous thromboembolism risk & prophylaxis in the acute hospital care setting (ENDORSE), a multinational cross-sectional study: results from the Indian subset data.

BACKGROUND & OBJECTIVES: Venous thromboembolism (VTE) is a major health problem with substantial morbidity and mortality. It is often underdiagnosed due to lack of information on VTE risk and prophylaxis. The ENDORSE (Epidemiologic International Day for the Evaluation of Patients at Risk for Venous Thromboembolism in the Acute Hospital Care Setting) study aimed to assess the prevalence of VTE risk in acute hospital care setting and proportion of at-risk patients receiving effective prophylaxis. We present here the risk factor profile and prophylaxis pattern of hospitalized patients who participated in ENDORSE study in India. METHODS: In this cross-sectional study in India, all patients (surgical >18 yr, medical >40 yr) from 10 hospitals were retrospectively studied. Demographics, VTE risk factors and prophylaxis patterns were assessed according to the 2004 American College of Chest Physicians (ACCP) evidence-based consensus guidelines. RESULTS: We recruited 2058 patients (1110 surgical, 948 medical) from 10 randomly selected hospitals in India between August 2006 and January 2007. According to the ACCP criteria, 1104 (53.6%) patients [surgical 680 (61.3%), medical 424 (44.7%)] were at-risk for VTE. Chronic pulmonary disease/heart failure and complete immobilization were the most common risk factors before and during hospitalization, respectively. In India, 16.3 per cent surgical and 19.1 per cent medical at-risk patients received ACCP-recommended thromboprophylaxis. INTERPRETATION & CONCLUSIONS: Despite a similar proportion of at-risk hospitalized patients in India and other participating countries, there was major underutilization of prophylaxis in India. It necessitates increasing awareness about VTE risk and ensuring appropriate thromboprophylaxis.

Retrospective evidence for clinical validity of expanded genetic model in warfarin dose optimization in a South Indian population.

AIM: To optimize warfarin dose in patients at risk for thrombotic events, we have recently developed a pharmacogenomic algorithm, which explained 44.9% of the variability in warfarin dose requirements using age, gender, BMI, vitamin K intake, CYP2C9 (*2 and *3) and VKORC1 (*3, *4 and -1639 G>A) as predictors. The aim of the current study is to develop an expanded genetic model that can explain greater percentage of warfarin variability and that has clinical validity. PATIENTS & METHODS: CYP2C9*8, CYP4F2 V433M, GGCX G8016A and thyroid status were added to an expanded genetic model (n = 243). RESULTS: The expanded genetic model explained 61% of the variability in warfarin dose requirements, has a prediction accuracy of ±11 mg/week and can differentiate warfarin sensitive and warfarin resistant groups efficiently (areas under receiver operating characteristic curves: 0.93 and 0.998, respectively; p < 0.0001). Higher percentage of International Normalized Ratios in therapeutic range (52.68 ± 4.21 vs 43.80 ± 2.27; p = 0.04) and prolonged time in therapeutic range (61.74 ± 3.18 vs 47.75 ± 5.77; p = 0.03) were observed in subjects with a prediction accuracy of <1 mg/day compared with subjects with prediction accuracy >1 mg/day. In the warfarin-resistant group, primary hypothyroidism was found to induce more resistance while in the warfarin-sensitive group, hyperthyroidism was found to increase sensitivity. CONCLUSION: The expanded genetic model explains greater variability in warfarin dose requirements and it prolongs time in therapeutic range and minimizes out-of-range International Normalized Ratios. Thyroid status also influences warfarin dose adjustments.

Deep vein thrombosis following laparoscopic hysterectomy in a nulliparous woman.

A nulliparous woman aged 45 years was referred to us with painful swelling in left lower limb. She underwent laparoscopic hysterectomy for menorrhagia 12 days prior to the admission. The laparoscopic surgery was completed in 90 min without blood loss and blood transfusion. The size of the uterus was approximately 12 weeks. Duplex scan of the left lower limb confirmed thrombosis of the left external iliac vein, femoral vein, popliteal vein and tibial veins. On examination the laparoscopic puncture wounds healed well. She was hospitalized for initial anticoagulation with low molecular weight heparin (Enoxapain 1 mg/kg body weight twice daily) and compression bandages. Histological examination of the hysterectomy specimen was noted to be benign (Adenomyosis and cervical Leiomyoma). She responded to anticoagulation therapy and was discharged with an advice to attend the follow up clinic for long term anticoagulation advice for the next 6 months to prevent recurrent thromboembolic episodes.
