This study was designed to describe the characteristics and clinical outcome of patients diagnosed with plantar vein thrombosis.
Patients presenting with sudden pain and/or swelling of the foot were evaluated by duplex scanning of the affected leg. All the main foot veins were imaged with high resolution multi-linear array transducers. The location and extent of thrombosis was recorded in detail. All patients were scheduled for clinical and ultrasound follow-up within a week from the diagnosis and at various intervals thereafter.
Acute thrombosis was found in the plantar veins in 11 patients of whom 7 were females. Pain was presented in all patients, swelling in 8 and the left foot was involved in 7. From the risk factors evaluated, the most common were recent surgery 4, use of contraceptive pills 3, followed by malignancy, airplane travel, HIV-AIDS infection, and past history of DVT in one each. Plantar veins were exclusively affected in 8, with lower segment of the posterior tibial veins in 2 and the great saphenous vein in 1. In the follow up, there was evidence of thrombosis extension in 3 patients. At six months partial recanalization was found in 9 and complete in 2.
Pain and swelling of the foot can be caused by plantar vein thrombosis. Complete or partial recanalization occurs in these patients by 6 months. Thrombi in the plantar veins can progress more proximally with the possibility of postthrombotic events.
本研究旨在描述诊断为足底静脉血栓形成患者的特征和临床转归。
通过对受影响腿部的双功能超声扫描评估出现足部突发疼痛和/或肿胀的患者。使用高分辨率多线性阵列换能器对所有主要足部静脉进行成像。详细记录血栓的位置和范围。所有患者均在诊断后一周内及以后的不同时间进行临床和超声随访。
11 名患者的足底静脉出现急性血栓形成，其中 7 名为女性。所有患者均出现疼痛，8 名患者出现肿胀，7 名患者为左脚受累。从评估的危险因素来看，最常见的是近期手术 4 例，使用避孕药 3 例，其次是恶性肿瘤、飞机旅行、HIV/AIDS 感染和过去深静脉血栓形成史各 1 例。8 例患者仅累及足底静脉，2 例患者后胫静脉下段受累，1 例患者大隐静脉受累。在随访中，3 例患者有血栓延伸的证据。6 个月时，9 例患者部分再通，2 例患者完全再通。
足部疼痛和肿胀可由足底静脉血栓形成引起。这些患者在 6 个月时会出现完全或部分再通。足底静脉内的血栓可能会向近端进展，并可能发生血栓后事件。
